a range of approaches for encouraging their visitors and communities to not only learn about climate solutions, but to discover their own pathways to sustained, meaningful participation in action. These place-based institutions have unique opportunities to cultivate a culture of hope and action thanks to their local expertise, diverse programming (e.g., field trips, special events, and community science projects), and wide reach (including both in-person and online interactions). These assets enable science centers and museums to communicate about climate solutions in ways that are visible, relatable, and accessible, all attributes that make them more likely to be taken up. One approach that several museums and other groups have piloted is the use of a GIS-based tool to invite members of their community to share the climate actions they’re undertaking and explore those of others. The tool produces open-access climate action maps that showcase real actions taking place in a particular community and provide an opportunity to leverage several evidence-based practices for communicating about climate solutions. By featuring everyday people who live in one’s community, doing actions that are broadly accessible, the maps build a sense of agency, provide inspiration, convey action-oriented norms, and build a sense of belonging in climate solutions. We will describe the ways that this flexible tool and resulting map can be embedded in a range of museum contexts and will discuss the ways that contributing to and exploring the map benefits museums, their visitors, and communities. We will also discuss opportunities for increasing impact through connections with local media, decision-makers, and K-12 school systems. This work demonstrates the role that science museums can play as hubs for collecting and coordinating climate stories and actionable resource centers for increasing community-led participation in climate action. </div> </a> </div> </div> </div> <div class="blog-card"> <a href="/doi/full/10.22541/essoar.173203125.57913538/v1"> <div class="blog-card__image-container"> <img

extreme wildfires in the Arctic tundra. Large fires burned in the carbon-rich permafrost landscape, releasing vast amounts of carbon, and changing land surface processes by burning vegetation and organic soils. However, little is known about the mosaics of burned and unburned patches formed by tundra fires and the underlying processes that generate them. In this study, we investigated six fire scars in the northeastern Siberian tundra using high-resolution PlanetScope imagery (3 m) to map burned fraction within the scars. We then used Bayesian mixed models to identify which biotic and abiotic predictors influenced the burned fraction. We observed high spatial variation in burned fraction across all tundra landforms common to the region. Current medium-resolution fire products could not capture this heterogeneity, thereby underestimating the burned area of fire scars by a factor of 1.1 to 4.4. The heterogeneity of the burn mosaic indicates a mix of burned and unburned patches, with median unburned patch sizes being smaller than 180 to 324 m². Pre-fire land surface temperature, vegetation heterogeneity and topography predicted burn fraction in our analysis, matching factors previously shown to influence large-scale fire occurrence in the Arctic. Future studies need to consider the fine-scale heterogeneity within tundra landscapes to improve our understanding and predictions of fire spread, carbon emissions, post-fire recovery and ecosystem functioning. </div> </a> </div> </div> </div> <div class="blog-card"> <a href="/doi/full/10.22541/essoar.173193420.03623709/v1"> <div class="blog-card__image-container"> <img

Radiometer Experiment on Space Station (ECOSTRESS) collects thermal observations from the International Space Station to support evapotranspiration (ET) research at fine spatial resolutions (70 m x 70 m). Initial ET estimates from ECOSTRESS Collection 1 have been used in a wide range of scientific studies and applications, though subsequent analyses identified areas for improvement. This study provides an overview of updates to ECOSTRESS Collection 2 ET and presents an accuracy assessment of ET and auxiliary variables against in situ data from AmeriFlux. Key updates in Collection 2 include: four independent model estimates of ET and improved auxiliary forcing data. We find the multi-model ensemble ET estimate achieves a root mean square error (RMSE) of 109 Wm-2 for instantaneous observations and 1.5 mm/day for daily retrievals. When considering uncertainty in energy balance closure approaches for site-level data, the RMSE improves to 48 Wm-2 for instantaneous ET. We observe variable performance based on time of day of ECOSTRESS image acquisition, climate and vegetation type. Evaluation of auxiliary data highlight limitations in down-scaled net radiation and relative humidity, contributing to a diurnal hysteresis in ET estimates. We provide accuracy metrics and model sensitivity to auxiliary data to facilitate user confidence, data adoption, interpretation, and applications. ECOSTRESS is the only instrument capable of providing ET at different times of day at high spatial scales; thus, this work is an important step toward enhancing the capabilities of satellite-driven ET models in resolving diurnal ET variations and guiding directions for future improvements. </div> </a> </div> </div> </div> <div class="blog-card"> <div class="blog-card__container"> <div

reactions, including aerobic respiration and contaminant transformation. Quantifying the relative contribution of the biolayer to whole-stream mass transformation remains challenging because it requires that hyporheic zone solute transport and reaction heterogeneity are explicitly captured within a single upscaled modeling framework. Here, we use field experiments and modeling to quantify mass transformation in the biolayer relative to other stream compartments. We co-injected and monitored several fluorescent tracers, including the reactive tracer resazurin, into a controlled experimental stream whose 8.5 cm hyporheic zone is isolated from groundwater. We characterized reactive transport in the water column and at multiple hyporheic zone depths by simultaneously fitting concentration time series measured at these locations to a new mobile-immobile model, using resazurin-to-resorufin transformation as an indicator of aerobic bioreactivity. Results show that the biolayer transformed 2× more resazurin to resorufin than all other stream compartments combined, and over half of all reactions occurred within 2 advective travel times through the reach. This hotspot and hot moment behavior is attributed to the biolayer’s propensity to rapidly acquire, transiently retain, and rapidly degrade stream-borne solutes. Model analysis shows that mass transformation is highest in the biolayer across a wide range of biolayer structural properties, including scenarios when the biolayer is less reactive than deeper regions of the hyporheic zone. Together, our results point to the biolayer as a common feature of streams and rivers that should be considered in network-scale models of river corridor biogeochemistry. </div> </a> </div> </div> </div> <div class="blog-card"> <div class="blog-card__container"> <div class='blog-card__top-row'> </div> <div class='blog-card__heading-container '> <a href="/doi/full/10.22541/essoar.173046855.50289201/v1"> <div class="blog-card__title"> Size fractionated suspended organic carbon and nitrogen from the offshore Eastern Tro... </div> </a> </div> <div class="blog-card__author-container"> <div class="blog-card__author-information"> <div class="blog-card__images-container"> <div class="blog-card__first-avatar"> <img alt="Clara Fuchsman" width="24" height="24" class="user-profile-pic" src="data:image/jpg;base64,iVBORw0KGgoAAAANSUhEUgAAACAAAAAgCAMAAABEpIrGAAAABGdBTUEAALGP C/xhBQAAACBjSFJNAAB6JgAAgIQAAPoAAACA6AAAdTAAAOpgAAA6mAAAF3Cc ulE8AAABU1BMVEW7Zcq7ZMq6ZMm8Z8q8acu8aMu2WsaxUMK0VsS7Zsq5YMiy UMOyUcOxT8K1WcW6ZMq6Y8nCd9DWot/XpeDKh9WzVMS3Xse5Yci+bczYpuDU nt3Und3TnN3XpuDKiNa2W8bjwen////05/a5YsmzU8PHgdPr0++xTsLarOLn yuzq0e+rQb3FfdK8Z8vDedDGf9LBcs64X8i5Ysi3Xce0VcStRb/8+PzBc87k wemsRL63XMfEe9Hpze2wTcK9a8zCdc/LidbCdtDhu+elNLmyUsOwTMG1WMXE etHkw+qwTcG3XMbFfNL37fnmyOzr0e/s1PDq0O64YMi4X8f+/v779/z9+/38 +fzFe9G9asu/bs3HgNPDd9CmNrqvS8GtRr/68/vAcs7lxevft+bjwOnWo9/t 2PGrQr7u2fH58frGf9Poy+3Ig9TMjde0V8WzVcS7Z8oAAABsc1SwAAAAAWJL R0Rw2ABsdAAAAAd0SU1FB+gLFRAXGCwdGkMAAAFcSURBVDgR3cHpWtNAGAbQ d96ZMZ3S0LpgBMH4EbQUq4gBlEIBWUJrVUAFcRfEXeD+/xH7EPYr4BxcOErh P9WGM9imwAxOIrUxFiRMyhpNnEDoS56Xg0O+o5DyOx2LOEKUvMtXrl7ruh7c 6O652dPbdyt0REYR8G5Lqj8auCNtd8uGCgdIWx6Uii0NytC9qlTuVx8MPxwB kSEexSIdo/HYuASP5clEUAtjEIeoOydlqj6tg5nZ+KnMzS8segSJDHWyJI2m JeJnoy15/uLl8gojEBnqZFIaTUusvspV5fWbNVlHACJDnbyVSnnDRe/e1z7I 3MeFeiECiQxdkJe1T+Hq5y+Cr7LpbzgH4ghpm1vyLUy25fuPljTqhqDCMUSU /JTUL1P4LX/qhlQ4TtHl/b993f+6aiXTOxw74jQ6t+P7u3QIBkLHIs4gtDEW JOwecR62FcEUzqeUQkrh4tkHSTIplXEmicIAAAAldEVYdGRhdGU6Y3JlYXRl ADIwMjQtMTEtMjFUMTY6MjM6MjQrMDA6MDCgN1C9AAAAJXRFWHRkYXRlOm1v ZGlmeQAyMDI0LTExLTIxVDE2OjIzOjI0KzAwOjAw0WroAQAAACB0RVh0c29m dHdhcmUAaHR0cHM6Ly9pbWFnZW1hZ2ljay5vcme8zx2dAAAAGHRFWHRUaHVt Yjo6RG9jdW1lbnQ6OlBhZ2VzADGn/7svAAAAGHRFWHRUaHVtYjo6SW1hZ2U6 OkhlaWdodAA2MDB63r21AAAAF3RFWHRUaHVtYjo6SW1hZ2U6OldpZHRoADYw MOkv7egAAAAZdEVYdFRodW1iOjpNaW1ldHlwZQBpbWFnZS9wbmc/slZOAAAA F3RFWHRUaHVtYjo6TVRpbWUAMTczMjIwNjIwNGAuk0oAAAATdEVYdFRodW1i OjpTaXplADE1MDI0QkLo1JUPAAAAPXRFWHRUaHVtYjo6VVJJAGZpbGU6Ly90 bXAvbGV0dGVyX2F2YXRhcnMvMi9DRi8xODdfMTAxXzIwMi82MDAucG5nVkaf 0AAAAABJRU5ErkJggg== " /> </div> <div class="blog-card__second-avatar"> <img alt="Jacob Cram" width="24" height="24" class="user-profile-pic" src="https://d197for5662m48.cloudfront.net/images/user/531468/profile_image/thumbnail-8d0bf947aec9fd27d14bcb34e30040cd.jpeg" /> </div> </div> <div> <div class="blog-card__authors-text"> <div class="blog-card-author-list" style="width: 100%;"> <a href="/users/561608"><p class="blog-card__owner">Clara A Fuchsman</p></a> <p class='blog-card__remaining-text'>and 1 more</p> </div> </div> <time datetime="2024-11-01" class="blog-card__date">November 01, 2024</time> </div> </div> </div> <div class='blog-card__preview-content-container'> <a href="/doi/full/10.22541/essoar.173046855.50289201/v1"> <div class='blog-card__preview-content'> Oxygen Deficient Zones (ODZs) are key areas of N loss, a process dependent on organic matter. Understanding the sources of organic matter to the ODZ is necessary to predict how biogeochemical cycles will respond to ocean changes. Size fractionated (5-20, 20-53, 53-180, 180-500, >500 µm) particulate organic C and N (POM) concentration and isotopic composition depth profiles from three stations in the offshore Eastern Tropical North Pacific (ETNP) ODZ were used to create previously missing ETNP specific particle size to carbon and nitrogen relationships for models, while gaining insights into the origins of POM in the ODZ. Since the within-ODZ Prochlorococcus assimilate nitrite, we used the resulting highly depleted d15N signal to trace organic matter of cyanobacterial origin to medium sized particles at the secondary chlorophyll maximum (SCM), and to >500 µm particles directly below the SCM. This organic nitrogen was consumed in the upper ODZ. Other POM maxima were seen at the zooplankton vertical migration maxima with the increase in POM marked in the 5-20 µm fraction. In the deep ODZ, below the zooplankton migration depth, POM concentrations in the 5-20 µm fraction were unusually small, the C:N ratios were extremely high (>20), and d15N was enriched (8-12‰), indicating degraded material. In deep samples, d13C was more depleted in larger particle size and correlated with enriched d15N, indicating increased degradation in 53-500 µm particles. This trend suggests an additional source of small particles, such as from in situ production, rather than just the fragmentation of large particles. </div> </a> </div> </div> </div> <div class="blog-card"> <div class="blog-card__container"> <div class='blog-card__top-row'> </div> <div class='blog-card__heading-container '> <a href="/doi/full/10.22541/essoar.172978609.92915710/v1"> <div class="blog-card__title"> Scaling Forest Ecophysiology from the Leaf to the Globe </div> </a> </div> <div class="blog-card__author-container"> <div class="blog-card__author-information"> <div class="blog-card__images-container"> <div class="blog-card__first-avatar"> <img alt="Troy Magney" width="24" height="24" class="user-profile-pic" src="data:image/jpg;base64,iVBORw0KGgoAAAANSUhEUgAAACAAAAAgCAAAAABWESUoAAAABGdBTUEAALGP C/xhBQAAACBjSFJNAAB6JgAAgIQAAPoAAACA6AAAdTAAAOpgAAA6mAAAF3Cc ulE8AAAAAmJLR0QAAKqNIzIAAAAHdElNRQfoCxUQFxVSrGb+AAABd0lEQVQ4 EYXBMW/TUBiG0ef9fB07KRDRwlLRDYGEqERnJtj5lVnY+RcgVMQCRIIBBUoq QVGTWCGu74cdZykD9xxN+D8jwUgwEowEI8FICLScawROS7QCHRNbHk0eaZnc XUAAR6tGtDwvVj7IXa7Nxkq5IOCiflheCXzwa3Y/nC9y12Z8t/6GXARa9dPA 1uzzcy5eDtCfZ/tMYgYEWsWr/PL4+O10vBjC7YNluT7YB6djyD27OJ9XLOfz RcaSR2tbP2CD0zGQvBiNcvLhcBBZzB9ndfbk7CdOx+jEGB2P7qBTjn4f8l70 jJbYEq1yyvHlCdMRPeMacbP+enTn3qwK9Ix/ZMN3vOC0YMfYcXpNebY6rH6U DT1jJ5ABIgv1Rz5cZTmiE9iKwy/V9zKK1w03ptmnUXxTio4mtBzVmyK4fKWR mmqUUcU9uSDQEZ4X0eW6RfRsHJ09RRcQ2PEGkDcgb5BHEK1AT2yJlgCxYyQY CUaCkWAkGAl/AYOijygcGIgdAAAAJXRFWHRkYXRlOmNyZWF0ZQAyMDI0LTEx LTIxVDE2OjIzOjIxKzAwOjAw8g9/GgAAACV0RVh0ZGF0ZTptb2RpZnkAMjAy NC0xMS0yMVQxNjoyMzoyMSswMDowMINSx6YAAAAgdEVYdHNvZnR3YXJlAGh0 dHBzOi8vaW1hZ2VtYWdpY2sub3JnvM8dnQAAABh0RVh0VGh1bWI6OkRvY3Vt ZW50OjpQYWdlcwAxp/+7LwAAABh0RVh0VGh1bWI6OkltYWdlOjpIZWlnaHQA NjAwet69tQAAABd0RVh0VGh1bWI6OkltYWdlOjpXaWR0aAA2MDDpL+3oAAAA GXRFWHRUaHVtYjo6TWltZXR5cGUAaW1hZ2UvcG5nP7JWTgAAABd0RVh0VGh1 bWI6Ok1UaW1lADE3MzIyMDYyMDEQRGfFAAAAEnRFWHRUaHVtYjo6U2l6ZQA2 NzMyQkJvPl5lAAAAPXRFWHRUaHVtYjo6VVJJAGZpbGU6Ly90bXAvbGV0dGVy X2F2YXRhcnMvMi9UTS8xNjNfMTYzXzE2My82MDAucG5ntbip+gAAAABJRU5E rkJggg== " /> </div> <div class="blog-card__second-avatar"> <img alt="ZOE PIERRAT" width="24" height="24" class="user-profile-pic" src="data:image/jpg;base64,iVBORw0KGgoAAAANSUhEUgAAACAAAAAgCAMAAABEpIrGAAAABGdBTUEAALGP C/xhBQAAACBjSFJNAAB6JgAAgIQAAPoAAACA6AAAdTAAAOpgAAA6mAAAF3Cc ulE8AAABOFBMVEWt1n2t1nys1Xyu1n+v14Ct1n6s1nym0nKh0Gui0Gyj0W2r 1Xql0nGm0nGp1Heo03XA35vP57TK5KvL5a3M5a/M5a6q1Hm+3pm73ZO63JO6 3JKh0Grn89n///+n03O53JDX68Cj0W6q1Hi02Yi3246s1XvW6r/e7suczWK5 3JHj8dSv14G83ZXy+OvH46eu1oCp1Hafz2f6/Pel0nCk0W+424/d7sqazF+d zmS12orp9Nyu1n6k0W70+e+32424246bzWGgz2mx2IPs9eGfz2bT6bmw14Pi 8NKy2Ibl8te324zo89qm0nO12omw14Hr9eDE4aLO5rLL5ay22oudzmXc7ciY y12n03Tb7ceUyVbA35zz+ey22ozf782i0W3m8tiz2Ybj8dLQ57XQ57bW6r6i 0Gur1XkAAADXM9c9AAAAAWJLR0RnW9PpswAAAAd0SU1FB+gLFRAXEszI810A AAE9SURBVDgR3cEHVsJQFAXAy/0/JCEoahQLPrBhV1SIDRV77w17x/0vQSVH IpYNOIP/JVSGv/AHVKPSPkB9MEh8EaZhWvaHCJ3ou5paBSJAI1ZX3+C6bmNT 3GhuaWltUwmC+BSiTrSLL5mSso5OgPhEdHW39rSle6Wvf0AGh1LDIzIayRAV xFg0Nh6XiWzOk8kpZ3pGZi1FooKGys/Ny0I0VpC+RS4ty4qtSASoV9ekd3zd 9GTD6dncknpLEwFmctsyH0krc0DKdnbTICoIJzshe8n9oV1PDg6Pjk/sOIgK Up2eiXs+Zhaznlxc5uxkHkSAKnol15mCVxgu3sjt3XImDyIQpk7ci2/7QR6X NEl8RSN29dT0zn3W6qWuaBDVwoRp2aVSybZenYRpMIzvqLQP0Ir4iVXwm5AP COEfegPkoiY4+uk2hgAAACV0RVh0ZGF0ZTpjcmVhdGUAMjAyNC0xMS0yMVQx NjoyMzoxOCswMDowMOkYPSoAAAAldEVYdGRhdGU6bW9kaWZ5ADIwMjQtMTEt MjFUMTY6MjM6MTgrMDA6MDCYRYWWAAAAIHRFWHRzb2Z0d2FyZQBodHRwczov L2ltYWdlbWFnaWNrLm9yZ7zPHZ0AAAAYdEVYdFRodW1iOjpEb2N1bWVudDo6 UGFnZXMAMaf/uy8AAAAYdEVYdFRodW1iOjpJbWFnZTo6SGVpZ2h0ADYwMHre vbUAAAAXdEVYdFRodW1iOjpJbWFnZTo6V2lkdGgANjAw6S/t6AAAABl0RVh0 VGh1bWI6Ok1pbWV0eXBlAGltYWdlL3BuZz+yVk4AAAAXdEVYdFRodW1iOjpN VGltZQAxNzMyMjA2MTk4uhzacQAAABN0RVh0VGh1bWI6OlNpemUAMTQzODhC QgKPJXoAAAA9dEVYdFRodW1iOjpVUkkAZmlsZTovL3RtcC9sZXR0ZXJfYXZh dGFycy8yL1pQLzE3M18yMTRfMTI1LzYwMC5wbmcBX+A1AAAAAElFTkSuQmCC " /> </div> </div> <div> <div class="blog-card__authors-text"> <div class="blog-card-author-list" style="width: 100%;"> <a href="/users/534071"><p class="blog-card__owner">Troy S Magney</p></a> <p class='blog-card__remaining-text'>and 2 more</p> </div> </div> <time datetime="2024-10-24" class="blog-card__date">October 24, 2024</time> </div> </div> </div> <div class='blog-card__preview-content-container'> <a href="/doi/full/10.22541/essoar.172978609.92915710/v1"> <div class='blog-card__preview-content'> The ability to optically detect reflected and emitted photons from vegetation has transformed our understanding of forest ecophysiology, enabling detailed assessments of photosynthesis and evapotranspiration across scales. This chapter explores the links between physiological processes, remote sensing signals and broader ecosystem fluxes. By integrating remote sensing data across scales (leaf, tower, aircraft, and satellite), we capture the interactions between forest structure, function, and environmental conditions. We address scaling challenges and consider the convergence and divergence of remote sensing signals and forest ecophysiological processes. Convergence in plant traits creates predictable relationships between canopy structure and function, facilitating estimates of forest processes at large scales, while divergence arises from stressors and nuanced interactions at finer scales. Ultimately, we aim to clarify when and why these phenomena emerge and their significance for characterizing forest functional dynamics. </div> </a> </div> </div> </div> <div class="blog-card"> <a href="/doi/full/10.22541/essoar.172970220.06666803/v1"> <div class="blog-card__image-container"> <img onerror="$(this).closest('a').remove()" height="200" class="blog-card__image-tag" loading="lazy" src="https://d197for5662m48.cloudfront.net/images/tagdashboard/banner/large-0f57237e39dd0c54df15afa034038147.jpg" /> </div> </a> <div class="blog-card__container"> <div class='blog-card__top-row'> </div> <div class='blog-card__heading-container '> <a href="/doi/full/10.22541/essoar.172970220.06666803/v1"> <div class="blog-card__title"> Revisiting k: Time-varying stream litter breakdown rates </div> </a> </div> <div class="blog-card__author-container"> <div class="blog-card__author-information"> <div class="blog-card__images-container"> <div class="blog-card__first-avatar"> <img alt="Caleb J Robbins" width="24" height="24" class="user-profile-pic" src="data:image/jpg;base64,iVBORw0KGgoAAAANSUhEUgAAACAAAAAgCAMAAABEpIrGAAAABGdBTUEAALGP C/xhBQAAACBjSFJNAAB6JgAAgIQAAPoAAACA6AAAdTAAAOpgAAA6mAAAF3Cc ulE8AAABX1BMVEW7Zcq7ZMq6ZMm8aMu8acu7Zsq8Z8q8Z8u5YsmzU8SxT8Ky UsO4X8e0VsSyUcOxUMK2Wsa0VcTPk9nYp+DSmty3XMfPlNrYpuDUnt3Vot/O ktnCdc+3XsezVMTFfdL////RmNuzU8P16Pfy4vW4Xse5YMi4X8jMi9fEe9H9 +v3Bc8+tR7/x3/TLidbAcs7lxevjwenaq+LRl9urQL2sQ77OkNioO7vz5PW/ bs20V8WzVcT37vnt2PG/b823Xce5YsjJhdXEedGvS8Hx4PS+bc316ff27Pi2 Wca4YMjMjNfAcc7v3PO5YcjWpN+yUMO+bs3FfNGwTMHNjti6Y8nr0u/DeNC6 ZMqxTsLcseTOkdmsRL6tRr/lxOv47/m+bMzDd9D48PmtRb/mxuvMjdewTcLL itbVn9706PfEetG2W8bXpuDVod6+bcy7Z8rareK9asy1WMXds+XBc860VsUA AAAgGysGAAAAAWJLR0R0322obQAAAAd0SU1FB+gLFRAXC6ijW50AAAFzSURB VDgR3cGHVhNBAAXQN29mFrMhAxGDqOAzmo0ag6IoxBbRKFIiYsWOvXf//xyz ZzdK+QPuxU5jjEHK9GA7ZsCcwRaEddYTtM45G4HYjAO7CnFx0BKlOAwVhuGJ jRiVh3eP7EEYqIzuHdu3/0Bh3NOgj7QTB5U6VC0fVupILfFEH32d0tH6seNq nGhq8mTjlKZiSyJHF5/WmWmcPaepmVm1wvkLulj1IDJkNHRJl9sOV+auXuvo eght3Sh6EBnCh3nVEoA3F0JTi0tzyxoJlgYZwod51RKA7W7oKHVrgiByZLSy rNvjFt3Vxp2O7t67rwdFx4fIGbq1R3r8xD2d1LOZWbWml/S8ChB99JUX0nqp 9VKrr5paT+LXevPWkciRtvhOqfeh/EEfP7Vbkk888Q+jqh/7/OVr+FYZ/f5j Ifq5+Ot3zRP/0Q6GeKUSEaW4C/o/a3VPgw3onXOeoHUgaB2ITZgBewD2YCtj DFIGKYOd5C8KIyy42yolnwAAACV0RVh0ZGF0ZTpjcmVhdGUAMjAyNC0xMS0y MVQxNjoyMzoxMSswMDowMHyAePkAAAAldEVYdGRhdGU6bW9kaWZ5ADIwMjQt MTEtMjFUMTY6MjM6MTErMDA6MDAN3cBFAAAAIHRFWHRzb2Z0d2FyZQBodHRw czovL2ltYWdlbWFnaWNrLm9yZ7zPHZ0AAAAYdEVYdFRodW1iOjpEb2N1bWVu dDo6UGFnZXMAMaf/uy8AAAAYdEVYdFRodW1iOjpJbWFnZTo6SGVpZ2h0ADYw MHrevbUAAAAXdEVYdFRodW1iOjpJbWFnZTo6V2lkdGgANjAw6S/t6AAAABl0 RVh0VGh1bWI6Ok1pbWV0eXBlAGltYWdlL3BuZz+yVk4AAAAXdEVYdFRodW1i OjpNVGltZQAxNzMyMjA2MTkxw8Bi1QAAABN0RVh0VGh1bWI6OlNpemUAMjA3 MzZCQoDpcToAAAA9dEVYdFRodW1iOjpVUkkAZmlsZTovL3RtcC9sZXR0ZXJf YXZhdGFycy8yL0NSLzE4N18xMDFfMjAyLzYwMC5wbmcPW4mHAAAAAElFTkSu QmCC " /> </div> <div class="blog-card__second-avatar"> </div> </div> <div> <div class="blog-card__authors-text"> <div class="blog-card-author-list" style="width: 100%;"> <a href="/users/846615"><p class="blog-card__owner">Caleb J Robbins</p></a> <p class='blog-card__remaining-text'>and 8 more</p> </div> </div> <time datetime="2024-10-23" class="blog-card__date">October 23, 2024</time> </div> </div> </div> <div class='blog-card__preview-content-container'> <a href="/doi/full/10.22541/essoar.172970220.06666803/v1"> <div class='blog-card__preview-content'> A document by Caleb J Robbins.

This study focuses on the role of leaf stomatal conductance, which is central to photosynthesis and transpiration. Previous research showed that existing stomatal conductance schemes yield divergent results within a land surface model (LSM), implying a knowledge gap. We further the investigation on the performance of five representative stomatal conductance schemes using a full-fledged LSM, VIC+, and conduct a comparison study over a period of one to two years at two U.S. sites, Blodgett and Duke. Our results reveal substantial differences in modeling outcomes for stomatal conductance, leaf water potential, and leaf CO2 concentration. To gain a better understanding of the divergence among the modeling results, we examine the reasonableness of hourly output variables. Boundaries for unreasonable results are first established using published data for similar conditions, combined with physical reasoning, and judgements thus circumventing limitations of the lack of observational data. Based on them, large portions of the output from these schemes are deemed unreasonable. Treating these schemes as equally plausible or of the same level of credence, we present a new approach in which the stomatal conductance is estimated by simultaneously using multiple plausible expressions derived from two different schemes. This results in the introduction of an additional variable that binds two schemes into a robust one. This new scheme gives a significantly lower percentage of unreasonable variable combinations in its outputs, demonstrating its effectiveness. </div> </a> </div> </div> </div> <div class="blog-card">

class='blog-card__preview-content'> Root zone water storage capacity (SR) plays a fundamental role in determining the magnitude of evapotranspiration (ET) during both average and extreme climatic conditions. While methods exist to estimate SR globally at relatively fine spatial scales, the effects of uncertainty in these broad-scale estimates on evapotranspiration are largely unknown. We present a new method to efficiently describe the relationships between SR and evapotranspiration across all possible values of SR, for a given climate. This approach replaces computationally expensive model sensitivity analyses and provides a means for characterizing the importance of uncertainty and spatial variability in SR across various climates and timescales. To demonstrate the utility of our framework, we apply our approach to nine sites across the United States that vary in their seasonal climatology. In doing so, we show that evapotranspiration can be dramatically different between sites even with the same SR. For example, a very shallow SR (15 mm) would limit evapotranspiration to 27% of its maximum value (given no storage limitation) in some sites but to only 68% in others. Furthermore, if SR was estimated to be 250 mm with an uncertainty of +- 20%, the effect on estimated evapotranspiration in Eel (a site in Northern California) would be significant (+- 10%) but negligible in Boulder (a site in the Colorado Rockies). Furthermore, we find distinct site-specific SR–ET relationships that substantially impact how uncertainty and spatial variability in landscape distributions of SRaffect evapotranspiration patterns. </div> </a> </div> </div> </div> <div class="blog-card"> <div class="blog-card__container"> <div class='blog-card__top-row'> </div> <div class='blog-card__heading-container '> <a href="/doi/full/10.22541/essoar.172910265.55068919/v1"> <div class="blog-card__title"> The Role of Land Surface Phenology in Understanding Climate Change: A Systematic Revi... </div> </a> </div> <div class="blog-card__author-container"> <div class="blog-card__author-information"> <div class="blog-card__images-container"> <div class="blog-card__first-avatar"> <img alt="Dhruvi Sedha" width="24" height="24" class="user-profile-pic" src="https://d197for5662m48.cloudfront.net/images/user/843270/profile_image/thumbnail-fd6b59ad8dde2bfb007620cbe520a69d.jpeg" /> </div> <div class="blog-card__second-avatar"> </div> </div> <div> <div class="blog-card__authors-text"> <div class="blog-card-author-list" style="width: 100%;"> <a href="/users/843270"><p class="blog-card__owner">Dhruvi Sedha</p></a> <p class='blog-card__remaining-text'>and 3 more</p> </div> </div> <time datetime="2024-10-16" class="blog-card__date">October 16, 2024</time> </div> </div> </div> <div class='blog-card__preview-content-container'> <a href="/doi/full/10.22541/essoar.172910265.55068919/v1"> <div class='blog-card__preview-content'> Land surface phenology (LSP) has emerged as a crucial indicator of ecosystem responses to climate change, offering insights into the complex interactions between terrestrial vegetation and environmental variables. This study provides a comprehensive review of LSP research in Gujarat, India, synthesizing advances in satellite-based phenological monitoring and identifying key knowledge gaps. We examine the utility of various remote sensing platforms, vegetation indices, and analytical approaches for characterizing phenological patterns across Gujarat's diverse landscapes. Our findings highlight the need for improved integration of fine-scale observations, standardization of phenological metrics, and mechanistic studies linking phenology to ecophysiological processes. We also emphasize critical research needs, including assessments of urbanization and climate change impacts on phenology, and the role of anthropogenic influences in shaping forest phenological patterns. This review provides a roadmap for future LSP research in Gujarat and similar regions globally. </div> </a> </div> </div> </div> <div class="blog-card"> <div class="blog-card__container"> <div class='blog-card__top-row'> </div> <div class='blog-card__heading-container '> <a href="/doi/full/10.22541/essoar.172926686.63091440/v1"> <div class="blog-card__title"> Ice and winter dissolved oxygen modelling in Lake Winnipeg </div> </a> </div> <div class="blog-card__author-container"> <div class="blog-card__author-information"> <div class="blog-card__images-container"> <div class="blog-card__first-avatar"> <img alt="Shuqi Lin" width="24" height="24" class="user-profile-pic" src="data:image/jpg;base64,iVBORw0KGgoAAAANSUhEUgAAACAAAAAgCAMAAABEpIrGAAAABGdBTUEAALGP C/xhBQAAACBjSFJNAAB6JgAAgIQAAPoAAACA6AAAdTAAAOpgAAA6mAAAF3Cc ulE8AAABOFBMVEWiiH6ih32hh32jioCki4GiiX+kioGjiX+afnOVd2yZfHGe g3iWeW6hh36ih36fhHqwmpLIubPJurS1oZmXem+eg3mqk4rFta6iiH+ghnzm 39z////t6eeTdWnHuLLGt7GWeG3Mvrjc0s6ghXudgXfPwbzo4d+JaFzFta/D s6yUdmvd1NCObmKafXL18vHw7OqQcWXDs63Es62iiH3Mvrnp5OGWeW2hhnyY fHHn4N7w7OvEtK6cgHWdgni2oZnj29j7+vqpkIeQcWaVeG2ZfHKbf3TNwLrs 5+XFtK6mjYOjiYCghnv29POVeGyMbF+RcmbCsqu/rqfMvbibgHWZfXK8qqLy 7u2Kal3LvLeljIKumI+xnJOdgnft6Oa0n5eOb2LJu7XBsKqvmZDKu7WnjoWf hHmfhXsAAAAbZdXYAAAAAWJLR0RnW9PpswAAAAd0SU1FB+gLFRAXE7vPw8sA AAE8SURBVDgR3cHpOgJhGAbg53vmm5oxUVLCaxkmZGdskT1rdrInu/M/BPKD GVwOwH3j31EKf2EAfkEYWhsgzYhJ/ERELduugwkn5oD1CGsg4naiMdmUSseb M81OCxFGtFpt8q7d6eiULldTIUgx4nZLj5ftlb7+nAy4mgpBinpwSLzh9Mjo 2PiE+K6mQtAkI+6UTBuuPZO1ffFdTYUQYjY/JzJfWFhMTYjvaiqEkPBiS8si K6trGfGLmiQCSLau5/ODG5uy1Z+T7dROyQDxhdj19rb2vZEDkcMjOR7OWpYH 4hNZKs7JyWn5TM4vCnJ5lbi+ie6C+EQzXbmVmurdvXyoWgbxhdFKrJpMPlTK zuNJIZfZfnp+ARHAKMq2HXstIWsX3+3HQYUgwtA6AtLUH0CEKX6Dn5RCjaqZ xL/yBu2oJd+Sz/1PAAAAJXRFWHRkYXRlOmNyZWF0ZQAyMDI0LTExLTIxVDE2 OjIzOjE4KzAwOjAw6Rg9KgAAACV0RVh0ZGF0ZTptb2RpZnkAMjAyNC0xMS0y MVQxNjoyMzoxOCswMDowMJhFhZYAAAAgdEVYdHNvZnR3YXJlAGh0dHBzOi8v aW1hZ2VtYWdpY2sub3JnvM8dnQAAABh0RVh0VGh1bWI6OkRvY3VtZW50OjpQ YWdlcwAxp/+7LwAAABh0RVh0VGh1bWI6OkltYWdlOjpIZWlnaHQANjAwet69 tQAAABd0RVh0VGh1bWI6OkltYWdlOjpXaWR0aAA2MDDpL+3oAAAAGXRFWHRU aHVtYjo6TWltZXR5cGUAaW1hZ2UvcG5nP7JWTgAAABd0RVh0VGh1bWI6Ok1U aW1lADE3MzIyMDYxOTi6HNpxAAAAE3RFWHRUaHVtYjo6U2l6ZQAxNzQ2M0JC 2rETFgAAAD10RVh0VGh1bWI6OlVSSQBmaWxlOi8vdG1wL2xldHRlcl9hdmF0 YXJzLzIvU0wvMTYyXzEzNl8xMjYvNjAwLnBuZxLt5ywAAAAASUVORK5CYII= " /> </div> <div class="blog-card__second-avatar"> <img alt="Jun Zhao" width="24" height="24" class="user-profile-pic" src="data:image/jpg;base64,iVBORw0KGgoAAAANSUhEUgAAACAAAAAgCAMAAABEpIrGAAAABGdBTUEAALGP C/xhBQAAACBjSFJNAAB6JgAAgIQAAPoAAACA6AAAdTAAAOpgAAA6mAAAF3Cc ulE8AAABUFBMVEVSvIlRvIlRvIhRu4hVvYtTvIpWvYxWvYtPuodCtn5JuINT vIlAtXw6snk7s3k9tHtQu4dSvIhPuoZUvIp4y6NjwpVDtn+J0a6X17iQ1LOS 1LST1bWV1rZEtn9txpz////H6dkmq2v8/f1OuoZUvYtpxZm95dIyr3Nsxptt xptoxJhux5y/5tOh2r43sXdLuYRIuIIxr3NcwJDm9e44snc3sXZYvo1Dtn73 /Pk0sHWU1bY2sXZXvoxUvYpqxZlbv488s3p5y6TZ8OVKuYQ5sndFt4BXvo1G t4BpxZi85dE5snhQu4hGt4FKuYNEtoB2yqH0+veR1LQ9tHpmw5bJ6tp4yqMr rG7w+fXE6NeW1rcqrG6O07LY8ORsxppvx506sniv4MhCtX4+tHvz+vd0yaA9 s3qa2Lqb2Lt+zac/tHxNuoWK0a+c2LtMuYU6s3kAAAAf1f/bAAAAAWJLR0Rv VQhhgQAAAAd0SU1FB+gLFRAXDDbHzj4AAAE/SURBVDgR3cF3P0JhGAbg+z33 q6IkIuN4PUbn2FtGJHvvvbM33/9P1A8nfALXhf9JWVkKf6EXfiN0AbUvyw/i JyJQWBQMFYc/lETAUuQhyqLlFbHKquqaGrvWjkRAeClqUyf1DY2S09QEwksx bhxxm1ta29oDHdIZ1iS8FLVxxO3qLuzp7ZP+AYLwIqmNI25i0M+hYekzmvDi u7hxxE349YgrydExIg+hC1JmXNxEemJSprqCIDxITM/Mzs0vyOLS8oqIXh1L gfjG1Nr6xubA1rZ0FCd2ZHevKBYrA/GF0ZVt2Y9MHMjh0bGcLJ86zlk0AOIT qTPn8m7q4vJKcq6NpsIngjdnt3f3D4/dT7fJpG3bz+mXIPGNiJpMJoQgQpnw h9dH0IIHEff5NEjtywGRj1mKX/CLZSkAyspS+FfeAN5iKW5Urf8hAAAAJXRF WHRkYXRlOmNyZWF0ZQAyMDI0LTExLTIxVDE2OjIzOjEyKzAwOjAwTWhiZAAA ACV0RVh0ZGF0ZTptb2RpZnkAMjAyNC0xMS0yMVQxNjoyMzoxMiswMDowMDw1 2tgAAAAgdEVYdHNvZnR3YXJlAGh0dHBzOi8vaW1hZ2VtYWdpY2sub3JnvM8d nQAAABh0RVh0VGh1bWI6OkRvY3VtZW50OjpQYWdlcwAxp/+7LwAAABh0RVh0 VGh1bWI6OkltYWdlOjpIZWlnaHQANjAwet69tQAAABd0RVh0VGh1bWI6Oklt YWdlOjpXaWR0aAA2MDDpL+3oAAAAGXRFWHRUaHVtYjo6TWltZXR5cGUAaW1h Z2UvcG5nP7JWTgAAABd0RVh0VGh1bWI6Ok1UaW1lADE3MzIyMDYxOTJayTNv AAAAE3RFWHRUaHVtYjo6U2l6ZQAxMzgyNkJCDXnpvQAAADx0RVh0VGh1bWI6 OlVSSQBmaWxlOi8vdG1wL2xldHRlcl9hdmF0YXJzLzIvSlovODJfMTg4XzEz Ny82MDAucG5nWDaF3QAAAABJRU5ErkJggg== " /> </div> </div> <div> <div class="blog-card__authors-text"> <div class="blog-card-author-list" style="width: 100%;"> <a href="/users/566491"><p class="blog-card__owner">Shuqi Lin</p></a> <p class='blog-card__remaining-text'>and 3 more</p> </div> </div> <time datetime="2024-10-18" class="blog-card__date">October 18, 2024</time> </div> </div> </div> <div class='blog-card__preview-content-container'> <a href="/doi/full/10.22541/essoar.172926686.63091440/v1"> <div class='blog-card__preview-content'> For lakes experiencing extended ice-cover seasons, ice phenology has a substantive impact on thermal structure and dissolved oxygen (DO) dynamics during winters. This study applied a three-dimensional lake model (AEM3D) in Lake Winnipeg over 2016-2018, spanning two full winter seasons. Sensitivity analysis showed that the modeled ice cover thickness, formation, and duration were most sensitive to snow depth and snow/ice albedo. The model well simulated the ice freeze-up timing with less than 5 days discrepancy, but it underestimated the ice cover thickness and overestimated the ice cover duration in the unusual warm winter (2016-2017). Inverse stratification was developed under the ice, but the model could not fully reproduce it due to a lack of a sediment heat flux component. DO decreased with the formation of ice cover, leading to bottom hypoxia over the lake. The model indicates that ice phenology (i.e., ice cover duration, and blue/white ice thickness) affects the extent of winter hypoxia. We observed the DO decreased to < 2 mg L-1 (i.e., anoxia) in the North Basin, along with inverse stratification forming near lakebed, and an oxygen depletion rate reached 0.14 mg L-1 d-1 in the winter of 2016-17. The model captured but underestimated DO decline near the lakebed and simulated around 8% and 70% of lake area reached anoxia in winters of 2016-17 and 2017-18, respectively. This work provides insight into ice formation, under-ice thermal structure, and winter oxygen concentrations in a large prairie lake, and the role of changing ice phenology on northern lake ecology.

Carbonyl sulfide (COS), an atmospheric gas used as a tracer in carbon cycle studies, has an inferred missing sink in high Northern latitudes. Boreal COS budgets typically account for the contribution by forests and ignore any uptake that wetland ecosystems, widespread in Northern latitudes, may contribute. The first direct measurements of the ecosystem-atmosphere COS exchange of a boreal wetland, presented here, demonstrate their likely importance in that Northern latitude COS budgets. The investigated wetland (Siikaneva, Finland) took up on average 11 pmol m−2s−1 COS, which was ~72 % of the nearby boreal forest COS uptake. During nighttime, the COS uptake rates were similar at both sites. Upscaling our measurements to the boreal region using the ORCHIDEE model revealed in a Northern wetland sink of ~13 Gg S/y, changing the budget model output from a small source to a COS sink impacting Northern latitudes carbon uptake estimates based on COS. </div> </a> </div> </div> </div> <div class="blog-card"> <div class="blog-card__container"> <div class='blog-card__top-row'> </div> <div class='blog-card__heading-container '> <a href="/doi/full/10.22541/essoar.172856814.48261656/v1"> <div class="blog-card__title"> Importance of considering memory effect and soil organic carbon for terrestrial carbo... </div> </a> </div> <div class="blog-card__author-container"> <div class="blog-card__author-information"> <div class="blog-card__images-container"> <div class="blog-card__first-avatar"> <img alt="Mengyao Zhao" width="24" height="24" class="user-profile-pic" src="data:image/jpg;base64,iVBORw0KGgoAAAANSUhEUgAAACAAAAAgCAMAAABEpIrGAAAABGdBTUEAALGP C/xhBQAAACBjSFJNAAB6JgAAgIQAAPoAAACA6AAAdTAAAOpgAAA6mAAAF3Cc ulE8AAABXFBMVEX+2hD+2g/+2Q/92Q/+2hT+2hX+2hL+2xb+2hb92Q791gD9 1QD92AT92hD91AD92AP+2hH92Q3+5FH+5l/+3Sb91wL+3Sj+5l7+5FT91wH+ 3i/+6nj+52b+52j+52f+52r+6nf+3zH92An////+983+2hP++Nb+6XT92Qv+ 3CH91wD92AX+4Dv+3zX+2xz+4kj+++b92Qz92Qr+++j+64L+7ZD+++n90QD+ 98/92Af+9cD+9sX+9b7+9L3+2xv+64P+7Yr90wD92Ab+403+4Db+4T7+4T3+ 9cL92Aj+2xf+3zP++uD++dn+87P9zQD+87T90gD++dz+/fL+3ST9zwD+8qv+ 75j+6nn+++X+4UD+9Lv+3i7+4UH++d7+++r++t/+/fj+4Dz+3B/+4Dj+3SX+ /Oz+63/+6XL+9Lr+6Xb+5mH+7IT+2xn+6HD+3jD+6nv+6Gr+6Gz92QkAAAA2 0XewAAAAAWJLR0RzQQk9zgAAAAd0SU1FB+gLFRAXKArEKu8AAAGgSURBVDgR 3cF3Q9NAHAbg371pLmkuHBcVtcVazWulpDKsowYRrLM4ceLee6Lf/w97xPUZ eB7ZTpSSilIiqiL/gSdKsCWoQMkfkFqoISLQYQ06ir1IQyoKUk9MqiHQqUkm Ums8O+kA8SBZtmPnrkkd6Knde/Y2mtP7WvvbrQMHUw3x4PKAPGQ7E9ocJs0M K20TBkrG4PIuydkiLmZJ9sIjzbn5BS4WRx3Eg8v7PMbjdt6e4El2G0VRDE6x aUIo8eDykkunaeqGy2dY9sMVu8qzwyiQClx+jkvneWF4kZcusxytJVd41dQF UoHLS14b8vqNm1y/xbKfJbd5J6kBUoHLSy7eXabhvXVypIb3uWFXOhpSgctL Phg85CM+NiTsEy4PiiJJHWQLXF7yqUme8bkZkVO9F3z5aq75+s3IQTy4vM+3 iX3HjWGHtO9Z+WDjQMkYJOt+/NQbrX3+kmZfZ4pv3zd/tDdb0wsNDfEUJDOJ uJ82d5kxQWqNZwsHJRVIHAIucpAwho5iL+pA/sKYAqDgBRVA/lFKRJSIKCWi fpPt4xdmgjWNcxoqvgAAACV0RVh0ZGF0ZTpjcmVhdGUAMjAyNC0xMS0yMVQx NjoyMzoyMyswMDowMGWQbjMAAAAldEVYdGRhdGU6bW9kaWZ5ADIwMjQtMTEt MjFUMTY6MjM6MjMrMDA6MDAUzdaPAAAAIHRFWHRzb2Z0d2FyZQBodHRwczov L2ltYWdlbWFnaWNrLm9yZ7zPHZ0AAAAYdEVYdFRodW1iOjpEb2N1bWVudDo6 UGFnZXMAMaf/uy8AAAAYdEVYdFRodW1iOjpJbWFnZTo6SGVpZ2h0ADYwMHre vbUAAAAXdEVYdFRodW1iOjpJbWFnZTo6V2lkdGgANjAw6S/t6AAAABl0RVh0 VGh1bWI6Ok1pbWV0eXBlAGltYWdlL3BuZz+yVk4AAAAXdEVYdFRodW1iOjpN VGltZQAxNzMyMjA2MjAz/koG6QAAABN0RVh0VGh1bWI6OlNpemUAMTY5MjhC QmpKfLQAAAA8dEVYdFRodW1iOjpVUkkAZmlsZTovL3RtcC9sZXR0ZXJfYXZh dGFycy8yL01aLzI1NF8yMThfMTYvNjAwLnBuZ9dVbVkAAAAASUVORK5CYII= " /> </div> <div class="blog-card__second-avatar"> <img alt="Wei He" width="24" height="24" class="user-profile-pic" src="data:image/jpg;base64,iVBORw0KGgoAAAANSUhEUgAAACAAAAAgCAAAAABWESUoAAAABGdBTUEAALGP C/xhBQAAACBjSFJNAAB6JgAAgIQAAPoAAACA6AAAdTAAAOpgAAA6mAAAF3Cc ulE8AAAAAmJLR0QAAKqNIzIAAAAHdElNRQfoCxUQGBHSWb4oAAABhElEQVQ4 EYXBwU4TURiG4ff7z+kUKEXQhhg0sjAokrj2ErxvbsKNysKFhqQFbIrOdOZ8 zpS98zy65v+CEcGIYEQwIhgRjMiAAWFAZkdgQECmJ9lINhJGtixR6GWw2rYK XKdsGldtmYTlWpURgdXN3+Riv5q3Kqdn3cnrVGTOFp1kArR99v6s6Q4/XGwd H989Xl7udSq6utrSC3C+5Yh2wWzazPjZdhhkWgYBpD8+Dj8nH9VzHhK4uBgx CHB09yml+Q9ebBesE7h0XeFJRkark5n5frzQcdlk84lBYZDp5eXb2YT16vww liVg2YY5FYMMOG042fvru/OX3An4cjdt02cxyPSifjxNX6vfvmCVO9jfTtvg SYAsbhPLqr6v2k2yKS6lYAbBIB4om+x7NtsgI0AkBpmeJ+ubNap+xSqTb2ZN cvhbk+npGoxKnSqra/LEarppWK41NSIDwnFAkdOBLU+xZe1TBGQGsgHZ9AoI 2exkdsRA9MSOeBKMCEYEI4IRwYhgxD/9aLT1xA/3lwAAACV0RVh0ZGF0ZTpj cmVhdGUAMjAyNC0xMS0yMVQxNjoyNDoxNyswMDowMP2MVroAAAAldEVYdGRh dGU6bW9kaWZ5ADIwMjQtMTEtMjFUMTY6MjQ6MTcrMDA6MDCM0e4GAAAAIHRF WHRzb2Z0d2FyZQBodHRwczovL2ltYWdlbWFnaWNrLm9yZ7zPHZ0AAAAYdEVY dFRodW1iOjpEb2N1bWVudDo6UGFnZXMAMaf/uy8AAAAYdEVYdFRodW1iOjpJ bWFnZTo6SGVpZ2h0ADYwMHrevbUAAAAXdEVYdFRodW1iOjpJbWFnZTo6V2lk dGgANjAw6S/t6AAAABl0RVh0VGh1bWI6Ok1pbWV0eXBlAGltYWdlL3BuZz+y Vk4AAAAXdEVYdFRodW1iOjpNVGltZQAxNzMyMjA2MjU3hFA2tQAAABJ0RVh0 VGh1bWI6OlNpemUAODQwMkJCACHqKwAAAD10RVh0VGh1bWI6OlVSSQBmaWxl Oi8vdG1wL2xldHRlcl9hdmF0YXJzLzIvV0gvMTk0XzE5NF8xOTQvNjAwLnBu Z2mD31YAAAAASUVORK5CYII= " /> </div> </div> <div> <div class="blog-card__authors-text"> <div class="blog-card-author-list" style="width: 100%;"> <a href="/users/699320"><p class="blog-card__owner">Mengyao Zhao</p></a> <p class='blog-card__remaining-text'>and 9 more</p> </div> </div> <time datetime="2024-10-10" class="blog-card__date">October 10, 2024</time> </div> </div> </div> <div class='blog-card__preview-content-container'> <a href="/doi/full/10.22541/essoar.172856814.48261656/v1"> <div class='blog-card__preview-content'> The terrestrial ecosystems of Qinghai-Tibet Plateau (QTP) are highly sensitive to climate change, yet the magnitude and distribution of the carbon budget for QTP remain quite uncertain. Here, utilizing long short-term memory networks (LSTM), in conjunction with available eddy covariance flux data from recent extensive observation campaigns, multiple satellite land surface data, and observation-based environmental data (e.g., soil organic carbon, SOC), we revisit the regional carbon budget estimation over the QTP with a special focus on investigating the impacts of considering memory effect and incorporating SOC. Our estimate points the QTP region to a mean carbon sink of 20.89 Tg C yr-1 during 2003–2018. Spatially, the major sinks distribute in the western and northern QTP dominated by alpine steppes, while major sources in the eastern QTP dominated by alpine meadows. During the study period, the regional sink declines at the rate of 0.0003 Tg C yr-2, which is primarily contributed by the reduced carbon sink of alpine steppes and the increased carbon source of alpine meadows. We found that considering memory effect and incorporating SOC are critical for estimating the regional carbon budget for QTP. Without considering memory effect leads to a huge carbon source of 161.10 Tg C yr-1, with unreasonable seasonal and interannual variation of carbon budgets. Without incorporating SOC leads to a larger estimated carbon sink (61.94 Tg C yr-1), with clearly overestimated sink in steppes ecosystems and underestimated source in meadows ecosystems. Our study provides new insights into the carbon budget estimation for the QTP region. </div> </a> </div> </div> </div> <div class="blog-card"> <div class="blog-card__container"> <div class='blog-card__top-row'> </div> <div class='blog-card__heading-container '> <a href="/doi/full/10.22541/essoar.172788193.38912352/v1"> <div class="blog-card__title"> Dynamic Bio-regionalisation of the Southern South China Sea: A Synthesis from Satelli... </div> </a> </div> <div class="blog-card__author-container"> <div class="blog-card__author-information"> <div class="blog-card__images-container"> <div class="blog-card__first-avatar"> <img alt="Mohd Ikmal Shafiq Rosli" width="24" height="24" class="user-profile-pic" src="data:image/jpg;base64,iVBORw0KGgoAAAANSUhEUgAAACAAAAAgCAMAAABEpIrGAAAABGdBTUEAALGP C/xhBQAAACBjSFJNAAB6JgAAgIQAAPoAAACA6AAAdTAAAOpgAAA6mAAAF3Cc ulE8AAABXFBMVEX+2hD+2g/+2Q/92Q/+2hX+2hH+2hP+2hT+2hb+2hL92Qv9 1gD91QD92Aj91wD92Q392AX92Qr+5Vf+5Vz+2xv92Ab91wL+4Dn+5mD+4kf9 2AP92Q7+6G7+52n+6Gz+4kb+3zL////+75v91AD92Qz+/vv+++f+7IX+3ir+ /vr++dr++uD+3iz+4Dv+/fL+4Dz+++r+5FT+2xr+9Lv92An++d790gD92Qn9 0QD+7pb+3Sf+7pX+/O3++NL+8KH+/PH+++j++d392Af+52T+7IT+3Sb+63/+ 6Xb90wD+6XL+3ST++uX+3B3+3i/+7pL+6nf9zwD+++n+/fP++uP+3i7+9b/+ +dz++uL+++b+2xf+4Db+/Ov+3Sj++NP90AD+6nb+9Lz+6nv+2xb+9sj+87f+ +t/92AT++Nf+87L+403+/O7+/Oz+2xj+6XT+8q7+3i3+637+5mH+6XMAAAA8 lNTOAAAAAWJLR0RzQQk9zgAAAAd0SU1FB+gLFRAXHCtw3loAAAG3SURBVDgR 3cHnVhNRGAXQ850pmTDXmQxNCIgeb0QUxRaKWBA1ECso2CtRsWHB9//hBHCx fAX2xkFihh1mBlgX/sOSAeCuIAhIYh8RhhEBMA4rRJgkSaVKYo8RPak7FBGM Mpcid6W0VgGxi1GR9Pb1D0SMBg8PDddHRkePjB1NXACiyxhnx6TjPkEjO6Fx D+046aogSsY4m5BO1YskHZZO+0KT/WfOTulcWqEBMMbZhM7rgrvoL0mTvqnp mdm5Pl32SWAAjHE2rytXr/mepq4v3PBNLc7cnLul2y4JDIAxzlpaWlbcvqO7 GveF7t1/MCT1D1ZpAIxx1tLDQa2sPnrsteZzdS2spzGJkjHO5vVkderpgMba euYLPX/xUq/aOYguY5y91pu37/ReI6nWfFOL7ZkNbfhOQJSMcdbSh3ZV+thu 6JOf1XSa16TaZpUGwBhn6/qc+i/66qlvvqHvbsv/0E9XIVFi1Nxa6q3Vf/1u zjaWt7PG8nY96ilW/hQjIErGqPApok2XR7lLo9ylIBrOETTsYNSpkNUOiCQk kpAgOqEZ/mHJSIJ7YCxhnxkAA2AGmKFkhoPjL0bNNfEbzztNAAAAJXRFWHRk YXRlOmNyZWF0ZQAyMDI0LTExLTIxVDE2OjIzOjEyKzAwOjAwTWhiZAAAACV0 RVh0ZGF0ZTptb2RpZnkAMjAyNC0xMS0yMVQxNjoyMzoxMiswMDowMDw12tgA AAAgdEVYdHNvZnR3YXJlAGh0dHBzOi8vaW1hZ2VtYWdpY2sub3JnvM8dnQAA ABh0RVh0VGh1bWI6OkRvY3VtZW50OjpQYWdlcwAxp/+7LwAAABh0RVh0VGh1 bWI6OkltYWdlOjpIZWlnaHQANjAwet69tQAAABd0RVh0VGh1bWI6OkltYWdl OjpXaWR0aAA2MDDpL+3oAAAAGXRFWHRUaHVtYjo6TWltZXR5cGUAaW1hZ2Uv cG5nP7JWTgAAABd0RVh0VGh1bWI6Ok1UaW1lADE3MzIyMDYxOTJayTNvAAAA E3RFWHRUaHVtYjo6U2l6ZQAxNzkxMUJCvHI7cAAAADx0RVh0VGh1bWI6OlVS SQBmaWxlOi8vdG1wL2xldHRlcl9hdmF0YXJzLzIvTVIvMjU0XzIxOF8xNi82 MDAucG5nSo676wAAAABJRU5ErkJggg== " /> </div> <div class="blog-card__second-avatar"> <img alt="Wee Cheah" width="24" height="24" class="user-profile-pic" src="data:image/jpg;base64,iVBORw0KGgoAAAANSUhEUgAAACAAAAAgCAAAAABWESUoAAAABGdBTUEAALGP C/xhBQAAACBjSFJNAAB6JgAAgIQAAPoAAACA6AAAdTAAAOpgAAA6mAAAF3Cc ulE8AAAAAmJLR0QAAKqNIzIAAAAHdElNRQfoCxUQFxFVwaLnAAABpUlEQVQ4 EYXBsU8TcRzG4c/7vd+1PcS2ogZEiDEsGoOLgyb+7S5MJsbEOJG4GCFApKWV IpRr716vuDh5z6MD/i9oEbQIWgQtghZBi0TDgAzIgDArYiUBlqhBMkg2EtgW jQSWbyO3FnUHVYs8g3mtlNsCEpZ5ejtJy2H3PKt625N5XT1er8aznixINOqX /pCq/fzjvHyx9WV6730HODrsySKB42Y67JZFzvAoBkz1pvPtJN/f/XXWMwQC TRjOh/Bw2Sl+X20Wp4eafWXPxiQa2fj5YPGk/LlDwUW1wbjI1haf6SATgNMV fW1MT+gVTKPLddTOLi/DFkEjyvL+OqNLBn1mmbkjISBAls+zXaZlvT2srlNJ UUt1sVYjCFayC/YW8+xsqz+u04QHc8/j7esSTNBwNiMbVWkMF8pHy51nZecV 35FFYiW7WaaR8glMk/j0bh84/VEY0AEYLR71j6tYbuXHQZTa7Hoy6ckCHdCw yqob1q27wlGVJuVYQGJF7mLLPWypjgKMRSPxVw2CGgTYNMRK4o5YEXfEP4IW QYugRdAiaBG0+AO85be79JsA6gAAACV0RVh0ZGF0ZTpjcmVhdGUAMjAyNC0x MS0yMVQxNjoyMzoxNyswMDowMB9QTcMAAAAldEVYdGRhdGU6bW9kaWZ5ADIw MjQtMTEtMjFUMTY6MjM6MTcrMDA6MDBuDfV/AAAAIHRFWHRzb2Z0d2FyZQBo dHRwczovL2ltYWdlbWFnaWNrLm9yZ7zPHZ0AAAAYdEVYdFRodW1iOjpEb2N1 bWVudDo6UGFnZXMAMaf/uy8AAAAYdEVYdFRodW1iOjpJbWFnZTo6SGVpZ2h0 ADYwMHrevbUAAAAXdEVYdFRodW1iOjpJbWFnZTo6V2lkdGgANjAw6S/t6AAA ABl0RVh0VGh1bWI6Ok1pbWV0eXBlAGltYWdlL3BuZz+yVk4AAAAXdEVYdFRo dW1iOjpNVGltZQAxNzMyMjA2MTk3KqPH4AAAABN0RVh0VGh1bWI6OlNpemUA MTI4MzRCQn0diRMAAAA9dEVYdFRodW1iOjpVUkkAZmlsZTovL3RtcC9sZXR0 ZXJfYXZhdGFycy8yL1dDLzE5NF8xOTRfMTk0LzYwMC5wbmc3b1TDAAAAAElF TkSuQmCC " /> </div> </div> <div> <div class="blog-card__authors-text"> <div class="blog-card-author-list" style="width: 100%;"> <a href="/users/838240"><p class="blog-card__owner">Mohd Ikmal Shafiq Rosli</p></a> <p class='blog-card__remaining-text'>and 4 more</p> </div> </div> <time datetime="2024-10-02" class="blog-card__date">October 02, 2024</time> </div> </div> </div> <div class='blog-card__preview-content-container'> <a href="/doi/full/10.22541/essoar.172788193.38912352/v1"> <div class='blog-card__preview-content'> The South China Sea (SCS) is one of the world’s most productive fishing zones. Regionalising the SCS, particularly the understudied southern sector (SSCS), is crucial for improving resource management in the SCS. In this study, we analysed 24 years of satellite-derived chlorophyll-a concentration (CHL) using a combination of empirical orthogonal function and Fuzzy C-mean clustering techniques. Our results reveal that the seasonal variability of CHL can be divided into three distinct regions. Broadly, these regions separate into the eastern and western basins. The first region encompasses the eastern boundary of the SSCS, the second region includes the area off the coast of Vietnam, and the central SSCS, while the third region extends from Karimata Straits to the Mekong River mouth. Each region exhibits unique seasonal CHL patterns: the first region shows a unimodal seasonality, while the second and third regions display bimodal seasonality. Beyond the climatological occupancy of these regions, we also demonstrate that their spatial extent is temporally dynamic. Regions can expand, contract, or shift entirely on an interannual scale. For instance, during the 1998 El Niño event, CHL variability in the deep basin experienced a marked changed due to intense warming. In contrast, during the 2015 El Niño event, despite similarly intense warming, CHL variability was statistically consistent with climatological norms. While the modulation of monsoonal winds by El Niño Southern Oscillation partially explains the interannual variability in the region. Our findings suggest that this variability is highly complex, likely due to the dynamic nature of the basin. </div> </a> </div> </div> </div> <div class="blog-card"> <a

Here, the effects of Russian olive on soil chemical properties and invertebrate communities in riparian zones of the southwestern U.S. were investigated. Russian olive stands were compared to native cottonwood stands and restoration sites by analyzing soil nitrogen (N), phosphorus (P) and moisture levels, and arthropod diversity and abundance. Sites where Russian olive is present led to a net increase in soil nitrogen, a decrease in soil phosphorus, and greater soil moisture compared to both native cottonwood stands and restoration sites. Native cottonwood stands showed lower soil N and higher P levels, as well as higher arthropod diversity. This increased diversity could be linked to the soil’s nutrient stoichiometry, as there is a negative correlation between taxonomic diversity and the soil N:P ratio. Moreover, there was a greater abundance of detritivorous arthropods in Russian olive stands compared to native vegetation. Soil nitrate (NO3-) levels showed a strong positive correlation with detritivorous arthropod abundance, but only a moderate correlation with herbivores, and NO3- was unrelated to predator abundance. These results suggest that Russian olive stands can alter soil chemistry in ways that disproportionately benefit detritivores, potentially disrupting the balance of arthropod communities and reducing overall biodiversity in riparian ecosystems. The study underscores the need for careful management of invasive, symbiotic N2-fixing plant species to preserve the ecological integrity of riparian habitats.Keywords: nitrate, phosphate, Rio Grande, Russian olive, soilINTRODUCTIONA persistent question in invasive species ecology is what are the functional roles of the invaders and their effect in the biodiversity and functional structure and composition of the recipient community (Renault et al., 2022; Galán Díaz et al., 2023). Invasive species can have cascading effects through different trophic levels and alter ecosystem functions, processes and services (McCary et al., 2016; Castro Díez and Alonso Fernández, 2017). One of the main effects of invasive plant species is the disruption of nutrient cycling and availability (Weidenhamer and Callaway, 2010; Afzal et al., 2023) which is especially relevant in invasions produced by woody and N2-fixing plants (Liao et al. 2008).Trees in symbiotic relationships with N2-fixing actinobacteria are globally reliable as invasive species and known to induce substantial effects on the N cycle relative to native vegetation (Vitousek et al. 1987, Nsikani et al. 2018, Collette and Pither 2015). These trees typically increase soil mineral N pools relative to native vegetation, and should be considered part of the ongoing anthropogenic global disruption of the nitrogen (N) cycle (Galloway, 1998; Galloway et al., 2008). Given that increased N is occurring with relatively less change to phosphorus (P) cycling, ecosystem responses are best understood in the context of increased N:P of major biotic and abiotic components (Penuelas et al., 2020).The ratio of N to P in leaves has long been understood to impact decomposition processes and nutrient cycling (Koerselman and Meuleman, 1996; Güsewell and Freeman, 2005). As part of the initial decomposition processes, soil and surface-active arthropods physically and chemically alter litter, and multiple experiments have demonstrated food preferences for litter based on a variety of chemical and structural properties (David, 2014). The direct mechanisms by which microbial use of arthropod frass contributes to soil organic material cycling are not fully clear, but there is evidence that microbial litter colonization directly increases litter palatability to arthropods when microbes increase litter nutritive value (Gerlach et al., 2012), or indirectly when microbes detoxify plant secondary compounds that hinder arthropod consumption and digestion of said litter (David 2014). Another established link between arthropods and soil microbes is that N mineralization is consistently increased following arthropod litter processing (David, 2014). Therefore, it is reasonable to assume that altered litter and soil N:P are filters on arthropod communities, which is plausible given that arthropods are likely phylogenetically constrained in their stoichiometry and feeding guilds (Martinson et al., 2008; Ross et al., 2022), and different community assemblages and functional groups are expected to inhabit this chemically shifted environment (Tie et al., 2021; Deng et al., 2022; Nessel et al., 2023). If detritivores, and to some extent herbivores, increase in abundance from higher N litter, feedbacks to the soil system may promote further increases in N:P via decomposed frass and dung inputs (Wolters, 2000), and increased N mineralization rates (David 2014). Changes in litter input can also change soil moisture quantity and dynamics, which would feedback to the above scenarios (Wang et al., 2020; Liu et al., 2021). Thus, an invader with impacts on soil N dynamics may be expected to also alter arthropod communities in ways that further change soil N pools and transformations.Invasive N2-symbiont trees therefore provide a natural experiment to evaluate the effect of N:P shifts on surface-active arthropod diversity and potential feedbacks to soil. Arid riparian zones in the southwestern USA have been significantly altered by the establishment of non-native vegetation (Dukes and Mooney, 2004; Harms and Hiebert, 2006), including by a tree with N2-fixing actinobacterial symbionts, Russian olive (Elaeagnus angustifolia ; Bertrand and Lalonde 1985). This species was introduced to riparian woodlands along the Rio Grande of New Mexico, USA, between 1900 and 1915 (Hink and Ohmart 1984). A major ecological disruption in the form ofreduced disturbance was a consequence of dams, levees and diversions that altered dynamic flood regimes of the river, and the relatively static channels of the Rio Grande are less suitable habitat for vegetation communities evolved to frequent overbank flooding and sedimentation (Rood and Mahoney, 1990; Shah and Dahm, 2008). The tree rapidly spread throughout the Rio Grande and became a dominant component of riparian vegetation by 1960 (Campbell and Dick-Peddie 1964). Native N2-fixing symbiotic trees are known in the region (Shepherdia argentea ; silver buffaloberry) but are locally rare and exhibit much lower fixation rates than Russian olive (Petrides 1998, Follstad Shah et al. 2010).Several reports document N cycling alterations following Russian olive invasion, including increased N loss from litter mass decomposed compared to cottonwood (Simons and Seastedt 1999). De Cant (2008) isotopically demonstrated N2-fixation from Russian olive in a Rio Grande bosque, and ~5-fold increase in foliar N compared to adjacent cottonwoods (Populus deltoides var.wislizenii ), but the native trees did not utilize increased soil N from fixation inputs. Decomposing Russian olive litter (C:N = 13) was observed to produce spikes in N2O not observed from cottonwood litter (C:N = 22) under laboratory conditions (Duval et al. 2020). That study also reports increased N-processing enzyme (leucine amino peptidase, LAP) activity from cottonwood soils, suggesting potential microbial N limitation not found with Russian olive soils. However, Russian olive soils exhibited slightly higher acid phosphatase activity compared to cottonwood (Duval et al. 2020), suggesting P limitation.Russian olive introductions clearly have impacts on soil N inputs and cycling, and recent evidence suggests the presence or removal of the tree alters riparian tree-dwelling arthropod communities (West et al., 2023). Ground-dwelling arthropods are excellent taxa to explore invasive tree effects on ecosystem processes, because they are sensitive to fine-scale environmental conditions, and these conditions themselves are vital contributors to decomposition and nutrient cycling in riparian areas (Perry and Herms 2017). Indeed, detritivorous arthropods generally respond well with increased nitrogen and phosphorus levels, with isopods increasing in abundance (Coccia and Fariña 2022). Ellis et al. (1999) found the species composition and richness of middle Rio Grande bosque ground-dwelling arthropods to be similar between native cottonwood and saltcedar habitats, but cottonwood habitats supported greater densities of non-native isopods. However, it is generally unknown what the arthropod community looks like in areas dominated by Russian olive and areas where it has been removed. To improve our knowledge of the ecosystem-level impacts of Russian olive, we designed a study to compare ground dwelling arthropod relative abundance and diversity (taxonomic and functional) in Russian olive dominated stands versus native cottonwood woodlands, and the effect of restoration efforts by comparing Russian olive stands with plots where the tree had been mechanically removed. This allows us to evaluate longer-term (decadal) influence of an invasive tree compared to historic vegetation, as well as short-term impacts on the arthropod community driven by physical removal of plants (and associated ecosystem effects) where the soil chemistry has perhaps not yet appreciably changed.Because we are centering our work on shifting stoichiometry due to a plant invasion, we quantify functional (feeding) diversity of surface-active arthropods as well as taxonomic diversity. We hypothesize that cottonwood stands will have significantly different arthropod communities (beta diversity; taxonomic and functional diversity) than Russian olive stands, and those will be related to soil chemical changes induced by the invasive tree, such as greater N pools and increased N:P (DeCant 2008; Peñuelas et al. 2020). Stands where Russian olive has been removed are predicted to be chemically similar to extant Russian olive stands, but arthropod communities will differ between these areas due to physical character alterations from plant removal (moisture retention, soil temperature). Addressing these questions will provide additional insight into the ecosystem effects of altered N:P on biogeochemically relevant biota, and feedbacks related to invasive, symbiotic N2-fixing vegetation in an arid riparian zone.MATERIALS & METHODS </div> </a> </div> </div> </div> <div class="blog-card"> <a href="/doi/full/10.22541/essoar.172711591.14380930/v1"> <div
