sea urchin. You’re a marine animal that attaches to hard surfaces for stability. You are covered in spikes to protect you from predators. You eat giant kelp – a type of seaweed. You prefer <strong>temperate</strong> water, typically between 5 to 16°C. But you’ve noticed that some days the ocean around you feels too hot. </p> <p>These periods of unusual warming in the ocean are called <strong>marine heatwaves</strong>. During marine heatwaves, water gets 2-3 degrees hotter than normal. That might not sound like much, but for an urchin, it is a lot. The ocean’s temperature is normally very consistent, so urchins are used to a small range of temperatures. Urchins are <strong>cold-blooded</strong>. This means they can’t control their own body temperature and rely on the water around them. Whatever temperature the ocean water is, they are too!</p> <p>Erin is a scientist who studies how environmental changes, like temperature, affect organisms. Erin first got excited about urchins when she interned with a research lab. When she started graduate school, she learned more about their biology and started to ask questions about how urchins would react to marine heatwaves. Hot water can speed up animals’ metabolisms, making them move and eat more. However, warmer temperatures can also cause stress, potentially causing urchins to be clumsier and confused.</p> <div class="wp-block-image"> <figure class="alignleft size-large is-resized"><a href="https://datanuggets.org/wp-content/uploads/2024/08/Erin-de-Leon-Sanchez-2-copy.jpeg"><img decoding="async" loading="lazy" src="https://datanuggets.org/wp-content/uploads/2024/08/Erin-de-Leon-Sanchez-2-copy-1024x823.jpeg" alt="" class="wp-image-9187" width="290" height="233" srcset="https://datanuggets.org/wp-content/uploads/2024/08/Erin-de-Leon-Sanchez-2-copy-1024x823.jpeg 1024w, https://datanuggets.org/wp-content/uploads/2024/08/Erin-de-Leon-Sanchez-2-copy-300x241.jpeg 300w, https://datanuggets.org/wp-content/uploads/2024/08/Erin-de-Leon-Sanchez-2-copy-768x618.jpeg 768w, https://datanuggets.org/wp-content/uploads/2024/08/Erin-de-Leon-Sanchez-2-copy.jpeg 1169w" sizes="(max-width: 290px) 100vw, 290px" /></a><figcaption class="wp-element-caption">Erin getting ready to scuba dive to look for urchins off the California coast.</figcaption></figure></div> <p>One summer, two science teachers, Emily and Traci, came to California to work in the same lab as Erin. Emily and Traci wanted to do science research so they can share their experience with their students.  As a team, they decided to test whether marine heat waves could be stressing urchins by looking at a simple behavior that they could easily measure. Healthy urchins have a <strong>righting</strong> instinct to flip over to orient themselves “the right way” using their sticky tube feet.</p> <p>The research team predicted that urchins would be slower to right themselves in warmer temperatures. However, they also thought the response could depend on the temperature the urchins were used to living in. If the urchins had been <strong>acclimated</strong> to higher temperatures, they might not be as strongly affected by the heatwaves.</p> <p>Together, Erin, Emily, and Traci took 20 urchins into her lab and split them into 2 groups. Ten were kept at 15°C, the ocean’s normal temperature in summer. The other ten were kept at 18°C, a marine heatwave temperature. They let the urchins acclimate to these temperatures for 2 weeks. They tested how long it took each urchin to right itself after being flipped over. They did this at three temperatures for each urchin: 15°C (normal ocean), 18°C (heatwave), and 21°C (extreme heatwave). They worked together to test the urchins three times at each temperature to get three replicates. Then they calculated the average of each urchin’s responses.</p> <p class="has-text-align-center"><em>Featured scientists: Erin de Leon Sanchez (she/her) from University of California – Santa Barbara, Emily Chittick (she/her), and Traci Kennedy (she/her) from Milwaukee Public Schools.</em></p> <p class="has-text-align-center"><em><a href="https://en.wikipedia.org/wiki/Flesch%E2%80%93Kincaid_readability_tests" target="_blank" rel="noreferrer noopener">Flesch–Kincaid Reading Grade Level</a> = The Content Level 3 activity has a score of 7.9 ; the Level 1 has a score of 5.9</em></p> <p><strong>Additional teacher resources related to this Data Nugget include:</strong></p> <ul> <li><a href="https://www.youtube.com/watch?v=OpDAwMHnFOU" title="">Here is a video</a> of a parrotfish finding and eating an urchin.

They grow in the salty waters along coastal areas. Seagrasses are important because they provide a lot of benefits for other species. Like land plants, seagrasses use sunlight and carbon dioxide to grow and produce oxygen in a process called photosynthesis. The oxygen is then used by other organisms, such as animals, for respiration. Other organisms use seagrasses for food and habitat. Seagrass roots hold sediments in place, creating a more stable ocean bottom. In addition, the presence of seagrasses in coastal areas slows down waves and absorbs some of the energy, protecting shorelines.</p> <p>Unfortunately, seagrasses are disappearing worldwide. Some reasons include damage from boats, disease, environmental changes, and storms. Seagrasses are sensitive to changes in their environment because they have particular conditions that they prefer. Temperature and light levels control how fast the plants can grow while salinity levels can limit their growth. Therefore, it is important to understand how these conditions are changing so that we can predict how seagrass communities might change as well.</p> <p>Ken is a plant ecologist who has been monitoring seagrasses in southern Texas for over 30 years! Because of his long-term monitoring of the seagrasses in this area, Ken noticed that some seagrass species seemed to be in decline. Kyle started working with Ken during graduate school and wanted to understand more about what environmental conditions might have caused these changes. </p> <div class="wp-block-image"> <figure class="alignleft size-full is-resized"><a href="https://datanuggets.org/wp-content/uploads/2024/06/Picture2.jpg"><img decoding="async" loading="lazy" src="https://datanuggets.org/wp-content/uploads/2024/06/Picture2.jpg" alt="" class="wp-image-9023" width="313" height="222" srcset="https://datanuggets.org/wp-content/uploads/2024/06/Picture2.jpg 831w, https://datanuggets.org/wp-content/uploads/2024/06/Picture2-300x214.jpg 300w, https://datanuggets.org/wp-content/uploads/2024/06/Picture2-768x547.jpg 768w" sizes="(max-width: 313px) 100vw, 313px" /></a><figcaption class="wp-element-caption">Manatee grass (<em>Syringodium filiforme</em>) located within the Upper Laguna Madre.</figcaption></figure></div> <p>Texas has more seagrasses than almost any other state, and most of these plants are found in a place called Laguna Madre. During his yearly seagrass monitoring, Ken noticed that from 2012 – 2014 one of the common seagrasses, called <strong>manatee grass</strong>, died at many locations across Laguna Madre. Since then, the seagrass has grown back in some places, but not others. Kyle thought this would be an opportunity to look back at the long-term dataset that Ken has been collecting to see if there are any trends in environmental conditions in years with seagrass declines.</p> <p>Each year, Ken, Kyle, and other scientists follow the same research protocols to collect data to monitor Laguna Madre meadows. Seagrass sampling takes place 2 – 4 times a year, even in winter! To find the manatee grass density, scientists dig out a 78.5 cm<sup>2</sup> circular section (10 cm diameter) of the seagrass bed while snorkeling. They then bring samples back to the lab and count the number of seagrasses. While they are in the field, they also measure environmental conditions, like water temperature and salinity. A sensor is left in the meadow that continuously measures the amount of light that reaches the depth of the seagrass.</p> <p>Kyle used data from this long-term monitoring to investigate his question about how environmental conditions may have impacted manatee grass. For each variable, he calculated the average across the sampling dates to obtain one value for that year. He wanted to compare manatee grass density with salinity, water temperature, and light levels that reach manatee grass. He thought there could be trends in environmental conditions in the years that manatee grass had low or high densities.</p> <p class="has-text-align-center"><em>Featured scientists: </em>Kyle Capistrant-Fossa (he/him) & Ken Dunton (he/him) from the U-Texas at Austin</p> <p class="has-text-align-center"><em><a href="https://en.wikipedia.org/wiki/Flesch%E2%80%93Kincaid_readability_tests" target="_blank" rel="noreferrer noopener">Flesch–Kincaid Reading Grade Level</a></em> <em>9.8</em></p> <p><strong>Additional teacher resources related to this Data Nugget:</strong></p> <p>There is <a href="https://datanuggets.org/2023/09/the-sound-of-seagrass/" title="">another Data Nugget that looks at these seagrass meadows</a>!

During some events, like high tides, the ocean water meets back up with the lagoon. Coastal lagoons are found all over the world – even in the most northern region of Alaska, called the <strong>High Arctic</strong>!</p> <p>These High Arctic lagoons go through many extreme changes each season. In April, ice completely covers the surface. The mud at the bottom of the shorelines is frozen solid. In June, the ice begins to break up and the muddy bottoms of the lagoons begin to thaw. The melting ice adds freshwater to the lagoons and lowers the salt levels. In August, lagoon temperatures continue to rise until there is only open water and soft mushy sediment.</p> <p>You would think these harsh conditions would make High Arctic lagoons not suitable to live in. However, these lagoons support a surprisingly wide range of marine organisms! Marine worms, snails, and clams live in the muddy sediment of these lagoons. This habitat is also called the bottom, or <strong>benthic</strong>, environment. Having a rich variety of benthic animals in these habitats supports fish, which migrate along the shoreline and eat these animals once the ice has left. And people who live in the Arctic depend on fishing for their food.</p> <p>Ken, Danny, and Kaylie are a team of scientists from Texas interested in learning more about how the extreme seasons of the High Arctic affect the marine life that lives there. They want to know whether the total number of benthic species changes with the seasons. Or does the benthic community of worms, snails, and clams stay constant throughout the year regardless of ice, freezing temperatures, and large changes in salt levels? The science team thought that the extreme winter conditions in the Arctic lagoons cause a die-off each year, so there would be fewer species found at that time. Once the ice melts each year, benthic animals likely migrate back into the lagoons from deeper waters and the number of species would increase again.</p> <p>Ken, Danny, and Kaylie had many discussions about how they could answer their questions. They decided the best approach would be to travel to Alaska to take samples of the benthic animals. To capture the changes in lagoon living conditions, they would need to collect samples during the three distinct seasons.</p> <div class="wp-block-image"> <figure class="alignleft size-full is-resized"><a href="https://datanuggets.org/wp-content/uploads/2023/03/benthic3.jpg"><img decoding="async" loading="lazy" src="https://datanuggets.org/wp-content/uploads/2023/03/benthic3.jpg" alt="" class="wp-image-8280" width="219" height="238" srcset="https://datanuggets.org/wp-content/uploads/2023/03/benthic3.jpg 448w, https://datanuggets.org/wp-content/uploads/2023/03/benthic3-275x300.jpg 275w" sizes="(max-width: 219px) 100vw, 219px" /></a><figcaption class="wp-element-caption">Benthic organisms from a sample</figcaption></figure></div> <p>The science team chose to sample Elson Lagoon because it is in the village of Utqiaġvik, Alaska and much easier to reach than other Arctic lagoons. They visited three times. First, in April, during the ice-covered time, again in June when the ice was breaking up, and a final time in summer when the water was warmer. In April, they used a hollow ice drill to collect a core sample of the frozen sediment beneath the ice. In June and August, they deployed a Ponar instrument into the water, which snaps shut when it reaches the lagoon bottom to grab a sample.

Carleigh and Chelsea, biology teachers in New Jersey, were at the beach one day when they saw a couple of stripers in the Barnegat Bay Inlet. Both teachers have always been interested in research and even met while participating in a summer research program as undergraduate students. Since then, both have gone on to complete more research projects in biology and education. Their curiosity about striper populations led them to work together yet again! </p> <p>They headed to Monmouth University in New Jersey, where they began working with two scientists, Megan and John. They learned that locations where fish reproduce are called <strong>spawning grounds</strong>. Young stripers spend 2-3 years developing in the spawning ground before moving downstream. When stripers become adults, they return to the same location to breed. </p> <p>There are four main spawning grounds for stripers on the East coast: the Hudson River, the Chesapeake Bay, Delaware River, and the Albermarle Sound. Stripers from these areas are considered to be different <strong>stocks</strong>. Stripers are migratory fish, and generally move north in the spring and south in the fall. Because they all migrate to New Jersey, fish from different stocks combine, which results in a <strong>mixed stock</strong>. When there is a population that has a mixed stock, we don’t know which spawning ground the fish originally came from. Conservation and management of New Jersey’s striper fishery requires knowing where the fish come from. Understanding which spawning grounds stripers are using helps managers make sure we are not overfishing or damaging these important environments. So, Carleigh and Chelsea joined a project that is working to find out how we can identify where mixed stock stripers come from. </p> <p>For their study, the scientists caught stripers in three different locations off the New Jersey coast in 2017. The fish were sampled by clipping off a small portion of the right pelvic fin. The scientists then extracted the DNA from each sample in the lab. They used polymerase chain reaction (PCR) to then copy regions of the DNA, called microsatellites. <strong>Microsatellites</strong> are small, repeating sections of DNA that can be variable enough to distinguish even close relatives. These data were then used to compare DNA samples from the unknown mixed stocks to the known spawning ground stocks. The scientists also recorded whether each fish was young or mature. The scientists then used the age data to tell whether the spawning grounds might be changing over time. </p> <figure class="wp-block-image"><img decoding="async" loading="lazy" width="1024" height="589" src="http://datanuggets.org/wp-content/uploads/2019/12/fishy-origins-map-1024x589.png" alt="" class="wp-image-6698" srcset="https://datanuggets.org/wp-content/uploads/2019/12/fishy-origins-map-1024x589.png 1024w, https://datanuggets.org/wp-content/uploads/2019/12/fishy-origins-map-300x173.png 300w, https://datanuggets.org/wp-content/uploads/2019/12/fishy-origins-map-768x442.png 768w" sizes="(max-width: 1024px) 100vw, 1024px" /></figure> <p class="has-text-align-center"><em>Featured scientists: Carleigh Engstrom, Chelsea Barreto, <a href="http://phiferrixeylab.com">Megan Phifer-Rixey</a>, and John Tiedemann from Monmouth University </em></p> <p class="has-text-align-center"><em><a rel="noreferrer noopener" href="https://en.wikipedia.org/wiki/Flesch%E2%80%93Kincaid_readability_tests" target="_blank">Flesch–Kincaid Reading Grade Level</a> = 9.2</em></p> </div><div class="post-meta"></div></div><div class="post-info"><span class="date published time" title="2019-11-04T14:28:24-05:00">11.4.19</span> </div><div class="post-6526 post type-post status-publish format-standard has-post-thumbnail hentry category-data-nugget tag-algae tag-animals tag-el-nino tag-marine entry"><h2 class="entry-title"><a class="entry-title-link" rel="bookmark" href="https://datanuggets.org/2019/11/crunchy-or-squishy/">Crunchy or squishy?

This allows warm surface waters that typically pile up on the western side of the Pacific Ocean to flow to the east. In South America, El Niño brings heavy rains and floods because the warm water moves toward that continent. On the other hand, the warm water moves away from the continent of Australia, causing drought. In the U.S., warm waters travel up to California during El Niño years, causing the ocean to be much warmer than usual. El Niño’s effects are so strong that it even changes the marine animals that live off the California coast in those years! </p> <p>Laura’s first experience with El Niño came when she was growing up in California. A strong El Niño event hit in 1997-98, and many cities in California flooded because of heavy rainstorms. The event even made the national news on TV! Laura’s second El Niño experience came in 2015, the year she started training to become a scientist. These events had such a big impact on her that she decided to study how zooplankton in the ocean are affected by El Niño. <strong>Zooplankton</strong> are tiny drifting ocean animals (“zoo” = animal + “plankton” = drifter) that eat <strong>phytoplankton </strong>(“plant drifters”). Zooplankton are important for the ocean’s food web because they are food for fish, whales, and seabirds. </p> <div class="wp-block-image"> <figure class="alignleft is-resized"><img decoding="async" loading="lazy" src="http://datanuggets.org/wp-content/uploads/2019/11/GelatinousZooplankton.jpg" alt="" class="wp-image-6533" width="261" height="211" srcset="https://datanuggets.org/wp-content/uploads/2019/11/GelatinousZooplankton.jpg 720w, https://datanuggets.org/wp-content/uploads/2019/11/GelatinousZooplankton-300x243.jpg 300w" sizes="(max-width: 261px) 100vw, 261px" /><figcaption class="wp-element-caption">Doliolids are a type of gelatinous zooplankton, meaning they have soft, watery bodies and not a lot of nutrition for other animals to eat. They can form large groups in the ocean called ‘blooms’.</figcaption></figure></div> <p>Zooplankton come in many shapes, sizes, and species. The two main groups are <strong>crustaceans</strong> and <strong>gelatinous animals</strong>. Crustaceans look like small shrimp and crabs, with hard, crunchy shells and segmented legs like insects. In contrast, gelatinous animals are watery and squishy, like jellyfish. Laura wanted to know how El Niño events might affect which group of zooplankton are found off the coast of California. </p> <p>Warm ocean waters during El Niño events have lower nutrient levels, so fewer phytoplankton grow leading to less food available for zooplankton. Gelatinous animals can survive in areas of the ocean where there is less food available. They are also able to live in warmer water than crustaceans. For these two reasons, Laura though that gelatinous animals may be able to live in the warmer water off California during El Niño events. Laura predicted that during the El Niño events of 1992-93, 1997-98, and 2015-16, the balance would shift in favor of gelatinous animals over crustaceans</p> <p>To test her idea, Laura used a long-term dataset that documents zooplankton collected offshore of southern California since 1951. Every spring, a ship goes out on the ocean and tows plankton nets for 30 minutes at 40 different locations. The ship brings back jars full of zooplankton. Scientists look at samples from those jars and identify the species and measure the lengths of each individual zooplankton in the sample. They then add up all the lengths of individual plankton to get the total biomass of each group. <strong>Biomass</strong> is similar to weight and shows us how big each animal is and how much space their group takes up. Scientists also measure water temperature and how much phytoplankton is found. The amount of phytoplankton is measured by detecting <strong>chlorophyll </strong>in the water. Chlorophyll from phytoplankton is a measure of how much food is available to zooplankton.</p> <div class="wp-block-image"> <figure class="aligncenter"><img decoding="async" loading="lazy" width="553" height="154" src="http://datanuggets.org/wp-content/uploads/2019/11/CrustaceanZooplankton.jpg" alt="" class="wp-image-6532" srcset="https://datanuggets.org/wp-content/uploads/2019/11/CrustaceanZooplankton.jpg 553w, https://datanuggets.org/wp-content/uploads/2019/11/CrustaceanZooplankton-300x84.jpg 300w" sizes="(max-width: 553px) 100vw, 553px" /><figcaption class="wp-element-caption">A euphausiid, or “krill”, is a type of crustacean zooplankton, meaning that it is related to shrimp and crabs.

In the 19<sup>th</sup> and 20<sup>th</sup> centuries, pressures on whales got even more intense as technology improved and the demand for whale products increased. This <strong>commercial whaling</strong> used to be very common in several countries, including the United States. Humpback whales were easy to hunt because they swim slowly, spend time in bays near the shore, and float when killed. Before commercial whaling, humpback whales were one of the most visible animals in the ocean, but by the end of the 20<sup>th</sup> century whaling had killed more than 200,000 individuals.</p> <p>Today, as populations are struggling to recover from whaling, humpback whales are faced with additional challenges due to <strong>climate change</strong>. Their main food source is krill, which are small crustaceans that live under sea ice. As sea ice disappears, the number of krill is getting lower and lower. Humpback whale population recovery may be limited because their main food source is threatened by ongoing ocean warming.</p> <p><img decoding="async" loading="lazy" class="alignleft wp-image-5355" src="http://datanuggets.org/wp-content/uploads/2017/11/WAPstudyarea-300x240.png" alt="" width="204" height="163" srcset="https://datanuggets.org/wp-content/uploads/2017/11/WAPstudyarea-300x240.png 300w, https://datanuggets.org/wp-content/uploads/2017/11/WAPstudyarea-768x613.png 768w, https://datanuggets.org/wp-content/uploads/2017/11/WAPstudyarea-1024x818.png 1024w, https://datanuggets.org/wp-content/uploads/2017/11/WAPstudyarea.png 1133w" sizes="(max-width: 204px) 100vw, 204px" />One geographic area that was over-exploited during times of high whaling was the South Shetland Islands along the Western Antarctic Peninsula (WAP). The WAP is in the southern hemisphere in Antarctica. Humpback whales migrate every year from the equator towards the south pole. In summer they travel 25,000 km (16,000 miles) south to WAP’s nutrient-rich polar waters to feed, before traveling back to the equator in the winter to breed or give birth. Today the WAP is experiencing one of the fastest rates of regional climate change with an increase in average temperatures of 6<sup>°</sup> C (10.8<sup>°</sup> F) since 1950. Loss of sea ice has been documented in recent years, along with reduced numbers of krill along the WAP.</p> <p>Logan is a scientist who is studying how humpback whales are recovering after commercial whaling. Logan’s work helps keep track of the number of whales that visit the WAP in the summer. He also determines the <strong>sex ratio</strong>, or ratio of males to females, which is important for reproduction. The more females in a population compared to males, the greater the potential for having more baby whales born into the next generation. Logan predicts there may be a general trend of more females than males along the WAP as the season progresses from summer to fall. Logan thinks that female humpback whales stay longer in the WAP because they need to feed more than males in order to have extra nutrients and energy before they birth their babies later in the year. This extra energy will be needed for their milk supply to feed their babies.</p> <p><div id="attachment_5382" style="width: 310px" class="wp-caption alignright"><img aria-describedby="caption-attachment-5382" decoding="async" loading="lazy" class="size-medium wp-image-5382" src="http://datanuggets.org/wp-content/uploads/2017/11/Palmer-Station-LTER-300x200.jpg" alt="" width="300" height="200" srcset="https://datanuggets.org/wp-content/uploads/2017/11/Palmer-Station-LTER-300x200.jpg 300w, https://datanuggets.org/wp-content/uploads/2017/11/Palmer-Station-LTER-768x512.jpg 768w, https://datanuggets.org/wp-content/uploads/2017/11/Palmer-Station-LTER-1024x683.jpg 1024w" sizes="(max-width: 300px) 100vw, 300px" /><p id="caption-attachment-5382" class="wp-caption-text">The Palmer LTER station when Logan and others scientists live while they conduct research on whales.</p></div></p> <p>Humpback whales only surface for air for a short period of time, making it difficult to determine their sex. In order to identify surfacing whales as female or male, scientists need to collect a <strong>biopsy</strong>, or a sample of living tissue, in order to examine the whale’s DNA. Logan worked with a team of scientists at Oregon State University and Duke University to engineer a modified crossbow that could be used to collect samples. Logan uses this crossbow to collect a biopsy sample each time they spot a whale. To collect a sample, Logan aims the crossbow at the whale’s back, taking care to avoid the dorsal fin, head, and fluke (tail). He mounts each arrow with a 40mm surgical stainless steel tip and a flotation device so the samples will bounce off the whale and float for collection. The samples are then frozen so they can be stored and brought back to the lab for analysis. Logan also takes pictures of each whale’s fluke because each has a pattern unique to that individual, just like the human fingerprint. Additionally, at the time of biopsy, Logan records the pod size (number of whales in the area) and GPS location.</p> <p>Logan’s data are added to the long-term datasets collected at the WAP. To address his question he used data from 2010-2016 along the WAP and other feeding grounds. Logan’s data ranges from January to April because those are the months he is able to spend at the research station in the WAP before it gets too cold. Logan has added to the scientific knowledge we have about whales by building off of and using data collected by other scientists.</p> <p style="text-align: center;"><em>Featured scientist: <a href="https://mmi.oregonstate.edu/people/logan-pallin">Logan J.

Logan first got interested in working with marine mammals when he was an undergraduate student at Duke University and had the opportunity to work as a field technician on a project with some scientists at Duke. He quickly realized this was what he wanted to do and that studying </span><span class="">humpbac whales was particularly interesting as they appear to have all rebounded quite heavily in the Southern Hemisphere</span><span class="">. Assessing why this recovery was happening so fast and why now, was something Logan really wanted to look at. After graduating from college, he continued to work with marine mammologists as a graduate student to receive his Masters in Science from Oregon State University. In the fall of 2017, he started his work on a PhD from University of California, Santa Cruz continuing asking questions and learning more about whales around Antarctica.</span><br /> <span style="border-top-left-radius: 2px;

They act as homes to large number of species, protect the coast from erosion during storms, and act as a filter for nutrients and pollution. Many species are unique to these habitats and provide crucial support to the marsh. For example, native <strong>eelgrass</strong>, a type of plant, minimizes erosion by holding sediments in place with their roots.</p> <p>In an effort to help protect and restore marshes, we must understand current-day issues that are affecting their health. The introduction of non-native species, species that are not originally from this ecosystem, into a marsh may disrupt the marsh ecosystem and threaten the survival of native species. One species that has recently caused a lot of trouble is the European<strong> green crab</strong>. This crab species was accidentally carried to the Atlantic coast back in the early 1800s from Europe. Since then, they have become extremely invasive and their numbers have exploded! Compared to native crabs, the green crab digs a lot when it searches for food and shelter. This digging uproots eelgrass and causes its population numbers to fall. In many spots where green crabs have been introduced, marshes are now bare and no more grass can grow.</p> <p><div id="attachment_1548" style="width: 310px" class="wp-caption alignleft"><a href="http://datanuggets.org/wp-content/uploads/2015/10/DSCF5225.jpg"><img aria-describedby="caption-attachment-1548" decoding="async" loading="lazy" class="size-medium wp-image-1548" src="http://datanuggets.org/wp-content/uploads/2015/10/DSCF5225-300x225.jpg" alt="Non-native green crabs caught in trap that has been underwater for 25 hours" width="300" height="225" srcset="https://datanuggets.org/wp-content/uploads/2015/10/DSCF5225-300x225.jpg 300w, https://datanuggets.org/wp-content/uploads/2015/10/DSCF5225-1024x768.jpg 1024w" sizes="(max-width: 300px) 100vw, 300px" /></a><p id="caption-attachment-1548" class="wp-caption-text">Non-native green crabs caught in trap that has been underwater for 25 hours</p></div></p> <p>The Great Marsh is one of the coastal habitats affected by invasive green crabs. Located on the North Shore of Massachusetts, the Great Marsh is known for being the longest continuous stretch of salt marsh in all of New England. Alyssa is a restoration ecologist who is very concerned with the conservation of the Great Marsh and other important coastal ecosystems. She and other scientists are trying to maintain native species while also reducing the effects of non-native species.</p> <p>A major goal for Alyssa is to restore populations of a native eelgrass. Eelgrass does more than just prevent erosion. It also improves water quality, provides food and habitat for native animal species, and acts as an indicator of marsh health. If green crabs are responsible for the loss of eelgrass from the marsh, then restorations where eelgrass is planted back into the marsh should be more successful where green crab numbers are low. Alyssa has been measuring green crab populations in different areas by laying out green crab traps for 24 hours. Alyssa has set these traps around Essex Bay, an area within the Great Marsh. She recorded the total number of green crabs caught at each location (as well as their body size and sex).</p> <p><div id="attachment_1549" style="width: 493px" class="wp-caption aligncenter"><a href="http://datanuggets.org/wp-content/uploads/2015/10/DSCF6375.jpg"><img aria-describedby="caption-attachment-1549" decoding="async" loading="lazy" class=" wp-image-1549" src="http://datanuggets.org/wp-content/uploads/2015/10/DSCF6375-1024x768.jpg" alt="Native eelgrass growing in Essex Bay, an area within the Great Marsh" width="483" height="362" srcset="https://datanuggets.org/wp-content/uploads/2015/10/DSCF6375-1024x768.jpg 1024w, https://datanuggets.org/wp-content/uploads/2015/10/DSCF6375-300x225.jpg 300w" sizes="(max-width: 483px) 100vw, 483px" /></a><p id="caption-attachment-1549" class="wp-caption-text">Native eelgrass growing in Essex Bay, an area within the Great Marsh</p></div></p> <p style="text-align: center;"><em>Featured scientist: <a href="http://sites.bu.edu/novak/" target="_blank" rel="noopener">Alyssa Novak</a>, Center for Coastal Studies/Boston University.

Many estuaries can be found along the Atlantic coast of North America. Reeds and grasses are the dominant type of plant in estuaries because they are able to tolerate and grow in the salty water. Where these reeds and grasses grow they form a special habitat called a <strong>salt marsh</strong>. Salt marshes are important because they filter polluted water and buffer the land from storms. Salt marshes are the habitat for many different kinds of plants, fish, shellfish, and birds.</p> <p><div id="attachment_1418" style="width: 322px" class="wp-caption alignleft"><a href="http://datanuggets.org/wp-content/uploads/2015/08/Senior-RA-Hap-Garritt-removing-YSI-logger-pipe-from-Middle-Road-bridge-in-winter.jpg"><img aria-describedby="caption-attachment-1418" decoding="async" loading="lazy" class="wp-image-1418" src="http://datanuggets.org/wp-content/uploads/2015/08/Senior-RA-Hap-Garritt-removing-YSI-logger-pipe-from-Middle-Road-bridge-in-winter.jpg" alt="Hap Garritt removing an oxygen logger from Middle Road Bridge in winter." width="312" height="416" srcset="https://datanuggets.org/wp-content/uploads/2015/08/Senior-RA-Hap-Garritt-removing-YSI-logger-pipe-from-Middle-Road-bridge-in-winter.jpg 400w, https://datanuggets.org/wp-content/uploads/2015/08/Senior-RA-Hap-Garritt-removing-YSI-logger-pipe-from-Middle-Road-bridge-in-winter-225x300.jpg 225w" sizes="(max-width: 312px) 100vw, 312px" /></a><p id="caption-attachment-1418" class="wp-caption-text">Hap Garritt removing an oxygen logger from Middle Road Bridge in winter.</p></div></p> <p>Scientists are worried because some salt marshes are in trouble! Runoff from rain washes nutrients, usually from lawn fertilizers and agriculture, from land and carries them to estuaries. When excess nutrients<strong>, </strong>such as <strong>nitrogen</strong> or <strong>phosphorus</strong>, enter an ecosystem the natural balance is disrupted. The ecosystem becomes more productive, called <strong>eutrophication</strong>. Eutrophication can cause major problems for estuaries and other habitats.</p> <p>With more nutrients in the ecosystem, the growth of plants and algae explodes. During the day, algae photosynthesize and release O<sub>2</sub> as a byproduct. However, excess nutrients cause these same algae grow densely near the surface of the water, decreasing the light available to plants growing below the water on the soil surface. Without light, the plants die and are broken down by decomposers. Decomposers, such as bacteria, use a lot of O<sub>2 </sub>because they respire as they break down plant material. Because there is so much dead plant material for decomposers, they use up most of the O<sub>2</sub> dissolved in the water. Eventually there is not enough O<sub>2 </sub>for aquatic animals, such as fish and shellfish, and they begin to die-off as well.</p> <p><em>Two features can be used to identify whether eutrophication is occurring. The first feature is low levels of dissolved O<sub>2</sub> in the water. The second feature is when there are large changes in the amount of dissolved O<sub>2</sub> from dawn to dusk.</em> Remember, during the day when it’s sunny, photosynthesis converts CO<sub>2</sub>, water, and light into glucose and O<sub>2</sub>. Decomposition reverses the process, using glucose and O<sub>2</sub> and producing CO<sub>2</sub> and water. This means that when the sun is down at night, O<sub>2</sub> is not being added to the water from photosynthesis. However, O<sub>2</sub> is still being used for decomposition and respiration by animals and plants at night.</p> <p>The scientists focused on two locations in the Plum Island Estuary and measured <strong>dissolved O<sub>2</sub></strong> <strong>levels</strong>, or the amount of O<sub>2 </sub>in the water. They looked at how the levels of O<sub>2</sub> changed throughout the day and night. They predicted that the <strong>upper</strong> part of the estuary would show the two features of eutrophication because it is located near an urban area. They also predicted the <strong>lower</strong> part of the estuary would not be affected by eutrophication because it was farther from urban areas.</p> <p><div id="attachment_1289" style="width: 606px" class="wp-caption aligncenter"><a href="http://datanuggets.org/wp-content/uploads/2013/12/salt-marsh-1.jpg"><img aria-describedby="caption-attachment-1289" decoding="async" loading="lazy" class=" wp-image-1289" src="http://datanuggets.org/wp-content/uploads/2013/12/salt-marsh-1.jpg" alt="A view of the Plum Island estuary" width="596" height="298" srcset="https://datanuggets.org/wp-content/uploads/2013/12/salt-marsh-1.jpg 690w, https://datanuggets.org/wp-content/uploads/2013/12/salt-marsh-1-300x150.jpg 300w" sizes="(max-width: 596px) 100vw, 596px" /></a><p id="caption-attachment-1289" class="wp-caption-text">A view of the Plum Island estuary</p></div></p> <p style="text-align: center;"><em>Featured scientists: <a href="https://www.marsci.uga.edu/directory/people/charles-hopkinson" target="_blank" rel="noopener">Charles Hopkinson</a> from University of Georgia and Hap Garritt from the <a href="http://www.mbl.edu/ecosystems/" target="_blank" rel="noopener">Marine Biological Laboratory Ecosystems Center</a></em></p> <p style="text-align: center;"><em><span id="Flesch.E2.80.93Kincaid_grade_level" class="mw-headline"><a href="https://en.wikipedia.org/wiki/Flesch%E2%80%93Kincaid_readability_tests" target="_blank" rel="noopener">Flesch–Kincaid Reading Grade Level</a> = 9.6</span></em></p> </div><div class="post-meta"></div></div><div class="post-info"><span class="date published time" title="2015-07-08T16:16:28-04:00">7.8.15</span> </div><div class="post-1290 post type-post status-publish format-standard has-post-thumbnail hentry category-uncategorized tag-animals tag-biodiversity tag-disturbance tag-fertilization tag-fish tag-marine tag-water tag-wetland entry"><h2 class="entry-title"><a class="entry-title-link" rel="bookmark" href="https://datanuggets.org/2015/07/can-mudsnails-disrupt-a-salt-marsh-foodweb/">The mystery of Plum Island Marsh</a></h2> <div class="entry-content"><p><div id="attachment_1291" style="width: 283px" class="wp-caption alignright"><a href="http://datanuggets.org/wp-content/uploads/2015/07/Harriet-Booth.jpg"><img aria-describedby="caption-attachment-1291" decoding="async" loading="lazy" class=" wp-image-1291" src="http://datanuggets.org/wp-content/uploads/2015/07/Harriet-Booth-1024x768.jpg" alt="Scientist, Harriet Booth, counting and collecting mudsnails from a mudflat at low tide." width="273" height="205" srcset="https://datanuggets.org/wp-content/uploads/2015/07/Harriet-Booth.jpg 1024w, https://datanuggets.org/wp-content/uploads/2015/07/Harriet-Booth-300x225.jpg 300w" sizes="(max-width: 273px) 100vw, 273px" /></a><p id="caption-attachment-1291" class="wp-caption-text">Scientist, Harriet Booth, counting and collecting mudsnails from a mudflat at low tide.</p></div></p> <p>The activities are as follows:</p> <ul> <li><a href="http://datanuggets.org/requesting-teacher-guides/">Teacher Guide</a></li> <li><a href="http://datanuggets.org/wp-content/uploads/2015/07/Mudsnails_StudentA.pdf">Student activity, Graph Type A, Level 3</a></li> <li><a href="http://datanuggets.org/wp-content/uploads/2015/07/Mudsnails_StudentB.pdf">Student activity, Graph Type B, Level 3</a></li> <li><a href="http://datanuggets.org/wp-content/uploads/2015/07/Mudsnails_StudentC.pdf">Student activity, Graph Type C, Level 3</a></li> <li><a href="http://datanuggets.org/wp-content/uploads/2016/09/Grading-Rubric-2016.pdf" rel="">Grading Rubric</a></li> <li>Optional classroom reading: <a href="http://datanuggets.org/wp-content/uploads/2015/07/Harriet-Booth.pdf">Harriet Booth: Unraveling the mysteries of Plum Island’s marshes</a></li> </ul> <p>Salt marshes are among the most productive coastal ecosystems. They support a diversity of plants and animals. Algae and marsh plants use the sun’s energy to make sugars and grow. They also feed many invertebrates, such as snails and crabs, which are then eaten by fish and birds. This flow of energy through the food web is important for the functioning of the marsh. Also important for the food web is the cycle of matter and nutrients. The waste from these animals, and eventually their decaying bodies, recycle matter and nutrients, which can be used by the next generation of plants and algae. Changes in any links in the food chain can have cascading effects throughout the ecosystem.</p> <p>Today, we are adding large amounts of fertilizers to our lawns and agricultural areas. When it rains, these nutrients run off into our waterways, ponds, and lakes. If the added nutrients end up in marshes, marsh plants and algae can then use these extra nutrients to grow and reproduce faster. Scientists working at Plum Island Marsh wanted to understand how these added nutrients affect the marsh food web, so they experimentally fertilized several salt marsh creeks for many years. In 2009, they noticed that fish populations were declining in the fertilized creeks.</p> <p><div id="attachment_1289" style="width: 574px" class="wp-caption aligncenter"><a href="http://datanuggets.org/wp-content/uploads/2013/12/salt-marsh-1.jpg"><img aria-describedby="caption-attachment-1289" decoding="async" loading="lazy" class=" wp-image-1289" src="http://datanuggets.org/wp-content/uploads/2013/12/salt-marsh-1.jpg" alt="View of a Plum Island salt marsh." width="564" height="282" srcset="https://datanuggets.org/wp-content/uploads/2013/12/salt-marsh-1.jpg 690w, https://datanuggets.org/wp-content/uploads/2013/12/salt-marsh-1-300x150.jpg 300w" sizes="(max-width: 564px) 100vw, 564px" /></a><p id="caption-attachment-1289" class="wp-caption-text">View of a Plum Island salt marsh.</p></div></p> <p>Fertilizer does not have any direct effect on fish, so the scientists wondered what the fertilizer could be changing in the system that could affect the fish. That same year they also noticed that the mudflats in the fertilized creeks were covered in mudsnails, far more so than in previous years. These mudsnails eat the same algae that the fish eat, and they compete for space on the mudflats with the small invertebrates that the fish also eat. The scientists thought that the large populations of mudsnails were causing the mysterious disappearance of fish in fertilized creeks by decreasing the number of algae and invertebrates in fertilized creeks.</p> <p>A few years later, Harriet began working as one of the scientists at Plum Island Marsh. She was interested in the mudsnail hypothesis, but there was yet no evidence to show the mudsnails were causing the decline in fish populations. She decided to collect some data. If mudsnails were competing with the invertebrates that fish eat, she expected to find high densities of mudsnails and low densities of invertebrates in the fertilized creeks. In the summer of 2012, Harriet counted and collected mudsnails using a quadrat (shown in the photo) and took cores down into the mud to measure the other invertebrates in the mudflats of the creeks. She randomly sampled 20 locations along a 200-meter stretch of creek at low tide. The data she collected are found below and can help determine whether mudsnails are responsible for the disappearance of fish in fertilized creeks.</p> <p><div id="attachment_1301" style="width: 573px" class="wp-caption aligncenter"><a href="http://datanuggets.org/wp-content/uploads/2015/07/mudsnails.jpg"><img aria-describedby="caption-attachment-1301" decoding="async" loading="lazy" class=" wp-image-1301" src="http://datanuggets.org/wp-content/uploads/2015/07/mudsnails-1024x531.jpg" alt="Mudsnails on a mudflat, and the quadrat used to study their population size." width="563" height="292" srcset="https://datanuggets.org/wp-content/uploads/2015/07/mudsnails.jpg 1024w, https://datanuggets.org/wp-content/uploads/2015/07/mudsnails-300x156.jpg 300w" sizes="(max-width: 563px) 100vw, 563px" /></a><p id="caption-attachment-1301" class="wp-caption-text">Mudsnails on a mudflat, and the quadrat used to study their population size.</p></div></p> <p style="text-align: center;"><em>Featured scientist: Harriet Booth from Northeastern University</em></p> <p style="text-align: center;"><em><span id="Flesch.E2.80.93Kincaid_grade_level" class="mw-headline"><a href="https://en.wikipedia.org/wiki/Flesch%E2%80%93Kincaid_readability_tests" target="_blank" rel="noopener">Flesch–Kincaid Reading Grade Level</a> = 10.2</span></em></p> <p style="text-align: left;"><strong><a href="http://datanuggets.org/wp-content/uploads/2015/07/Harriet-Booth.pdf" target="_blank" rel="noopener">Click here</a> for a great blog post by Harriet detailing her time spent in the salt marsh: <a title="Permanent Link: Harriet Booth: Unraveling the mysteries of Plum Island’s marshes" href="http://datanuggets.org/wp-content/uploads/2015/07/Harriet-Booth.pdf" rel="bookmark">Harriet Booth: Unraveling the mysteries of Plum Island’s marshes</a></strong></p> <p><strong>If your students are looking for more information on trophic cascades in salt marsh ecosystems, check out the video below!</strong></p> <ul> <li>A video in BioInteractive’s “Scientists at Work” series showing researchers working on the same questions in a different river system: <a href="http://www.hhmi.org/biointeractive/trophic-cascades-salt-marsh-ecosystems">Trophic Cascades in Salt Marsh Ecosystems</a></li> </ul> <p><iframe loading="lazy" id="_ytid_93792" width="480" height="270" data-origwidth="480" data-origheight="270" src="https://www.youtube.com/embed/b9xVEeYAs3w?enablejsapi=1&autoplay=0&cc_load_policy=0&cc_lang_pref=&iv_load_policy=1&loop=0&modestbranding=0&rel=1&fs=1&playsinline=0&autohide=2&theme=dark&color=red&controls=1&" class="__youtube_prefs__ epyt-is-override no-lazyload" title="YouTube player" allow="accelerometer;

While organisms can safely eat most phytoplankton, some produce toxins. When these toxic algae reach high population levels it is known as a <strong>toxic algal bloom</strong>. These blooms are occurring more and more often across the globe – a worrisome trend! Toxic algae poison animals that eat them, and in turn, humans that eat these animals. For example, clams and other shellfish filter out large quantities of the toxic algae, and the toxic cells accumulate in their tissues. If humans then eat these contaminated shellfish they can become very sick, and even die.</p> <p>One reason the algae produce toxins is to reduce predation. However, if predators feed on toxic prey for many generations, the predator population may evolve resistance, by natural selection, to the toxic prey. In other words, the predators may adapt and would be able to eat lots of toxic prey without being poisoned. Copepods, small crustaceans and the most abundant animals in the world, are main consumers of toxic algae. Along the northeast coast of the US, there is a toxic phytoplankton species, <em>Alexandrium fundyense</em>, which produces very toxic blooms. Blooms of <em>Alexandrium</em> occur often in Maine, but are never found in New Jersey. Scientists wondered if populations of copepods that live Maine were better at coping with this toxic prey compared to copepods from New Jersey.</p> <p><div id="attachment_767" style="width: 310px" class="wp-caption alignleft"><a href="http://datanuggets.org/wp-content/uploads/2014/08/copepod-and-toxic-Alexandriium-sp.png"><img aria-describedby="caption-attachment-767" decoding="async" loading="lazy" class="size-medium wp-image-767" src="http://datanuggets.org/wp-content/uploads/2014/08/copepod-and-toxic-Alexandriium-sp-300x188.png" alt="Figure 2: A photograph of a copepod (left) and the toxic alga Alexandrium sp.

To do this, they raised copepods from Maine (long history of exposure to toxic <em>Alexandrium</em>) and New Jersey (no exposure to toxic <em>Alexandrium</em>) in the laboratory. They raised all the copepods under the same conditions. The copepods reproduced and several generations were born in the lab (a copepod generation is only about a month). This experimental design eliminated differences in environmental influences (temperature, salinity, etc.) from where the populations were originally from.</p> <p>The scientists then measured how fast the copepods were able to produce eggs, also called their egg production rate. Egg production rate is an estimate of growth and indicates how well the copepods can perform in their environment. The copepods were given either a diet of toxic <em>Alexandrium</em> or another diet that was non-toxic. If the copepods from Maine produced more eggs while eating <em>Alexandrium, </em>this would be evidence that copepods have adapted to eating the toxic algae. The non-toxic diet was a control to make sure the copepods from Maine and New Jersey produced similar amounts of eggs while eating a good food source. For example, if the copepods from New Jersey always lay fewer eggs, regardless of good or bad food, then the control would show that. Without the control, it would be impossible to tell if a difference in egg production between copepod populations was due to the toxic food or something else.</p> <p style="text-align: center;"><em>Featured scientists: <a href="https://finiguerra.eeb.uconn.edu/me/" target="_blank" rel="noopener">Michael Finiguerra</a> and Hans Dam from University of Connecticut-Avery Point, and David Avery from the Maine Maritime Academy</em></p> <p style="text-align: center;"><em><span id="Flesch.E2.80.93Kincaid_grade_level" class="mw-headline"><a href="https://en.wikipedia.org/wiki/Flesch%E2%80%93Kincaid_readability_tests" target="_blank" rel="noopener">Flesch–Kincaid Reading Grade Level</a> = 10.6</span></em></p> <p style="color: #434345; text-align: left;"><strong>There are three scientific papers associated with the data in this Data Nugget.
