be phytosanitary threats on a wide diversity of plants and can have important economic and ecological impacts in their native area. This is the case of some species within the jewel beetle subfamily Agrilinae (Coleoptera: Buprestidae), which are associated with broadleaf forest declines and diebacks (Jendek &amp; Poláková, 2014). These thermophilous borers are expected to be favoured by climate change and the global deterioration of forest health, and ultimately expand their range and damage. &nbsp;</p> <p>Active flight plays a crucial role in the life strategies of most insects, facilitating essential activities such as mate searching, locating trophic resources, finding favorable environmental conditions, and dispersing to or colonizing new geographic areas (Dudley, 2002). Studying flight capacities provides valuable insights into the ecology of these species and helps estimate their ability to spread within new environments. Assessing the flight capacities of pest and alien species is therefore critical for evaluating their dispersal potential and for designing effective monitoring and control strategies.&nbsp;</p> <p>The study by Le Souchu et al. (2024) aimed to assess intra- and interspecific variability in active flight of several Agrilinae species and to evaluate the effects of sex and mass on this variability. Using computerised flight mills, they assessed the flight performance of twelve species, most of them associated with oaks. A key feature of the study is the extensive dataset used, which reveals significant variability in flight distance and capacity among species and individuals. Body mass positively influenced flight capacity in some species, while no sexual dimorphism was observed. The findings suggest a generally low average dispersal propensity within these species and highlight the critical role of rare, exceptional individuals in driving colonization and spread patterns at both population and species levels.</p> <p>Overall, the study provides a valuable comparative analysis of flight behavior and performance in several Agrilinae species associated with oak forests. Because flight behaviour and performance of these insects are poorly known despite their critical role in dispersal inside and outside native ranges and their relevance for management purposes, this study contributes to filling this gap. From a broader perspective, the findings revealed several common traits among the studied species and provide insights into the influence of different factors on flight activity.</p> <p><strong>References</strong></p> <p>Dudley, R.

Environmental variations challenge organisms' ability to maintain homeostasis leading to divergent adaptations between habitat specialists and generalists (Kawecki and Ebert, 2004). The article by (Keilani et al.) (2024) presents an original contribution to this field by focusing on the response to dry conditions in two rodent species from semi-arid regions of South Africa. The two species, <em>Rhabdomys bechuanae</em> and <em>R.dilectus dilectus</em>, have different environmental niches : <em>R.dilectus dilectus</em> occurring in mesic habitats while <em>R. bechuanae</em> is found in semi-arid and arid habitats. Previous studies highlighted morphological and behavioral adaptations to arid conditions in <em>R. bechuanae</em> (Dufour et al., 2019), the current study focuses on the physiological responses of the two species to seasonal dry conditions. By analyzing body condition, markers of kidney and liver functions, and habitat characteristics the authors aim to understand how aridity impacts parapatric populations of the two species. They hypothesize that i) the aridity of the habitat tend to increase during the dry season, ii) both species can adjust their physiology to dry conditions thanks to phenotypic plasticity, and iii) &nbsp;<em>R. bechuanae</em>, having evolved in arid environments, will cope better with dry conditions than <em>R. d. dilectus</em>.<br>Consistent with their prediction, Keilani et al (2024) found physiological divergence between the two species. They also observed six blood markers (out of 12 tested) showing significant temporal changes, indicating resource depletion as the dry season progressed, even though the year of study was influenced by a relatively mild La Niña event (i.e. wet year). Both species displayed similar physiological responses to the dry conditions, such as reduced blood albumin level by the end of the dry season, confirming albumin as a reliable indicator of malnutrition and nutrient deficiency (AL Eissa et al., 2012). In terms of interspecific differences, <em>R. bechuanae</em> exhibited better water regulation, with lower sodium, potassium, and total bilirubin levels, which may indicate adaptation to drier environments. The study concludes that <em>R. bechuanae</em> appears better adapted to cope with arid conditions, highlighting the importance of physiological studies in understanding species' responses to climate change, and suggests that harsher dry seasons could further challenge <em>R. d. dilectus</em>, particularly in semi-arid zones. This study underscores the value of studying species in their natural environments to fully understand the scope and limitations of their responses to environmental changes.</p> <p><strong>References</strong></p> <p>Dufour, C.M.S., Pillay, N., Avenant, N., Watson, J., Loire, E., and Ganem, G.

Yet, the efficiency of pathogenic fungi is dependent upon many factors that need to be evaluated to improve biological control potential in the fields (Lacey, 2001). The article by Chailleux et al. (2024) presents an exciting contribution to the field of biological pest control, specifically focusing on using entomopathogenic fungi to manage the oriental fruit fly, <em>Bactrocera dorsalis</em>. This fly, a member of the Tephritidae family, is a major threat to orchards in Asia, the Pacific and Africa, as it attacks fruit and causes considerable damage, in addition to having a relatively rapid biological invasion dynamic (Clarke et al. 2005).&nbsp;</p> <p>The objective of the Chailleux et al. (2024) study was to evaluate the virulence of <em>Metarhizium anisopliae</em>&nbsp;spores (strain Met69) on&nbsp;<em>B. dorsalis</em> adult flies according to various conditions: the inoculation dose and spore load, the formulation (adjuvant) and temperature conditions. The focus on host specificity and on-target applications was conducted to ensure minimal impact on non-target organisms, which is crucial for sustainable agriculture. The main challenge in this system was to achieve high strain virulence to kill wild individuals with a low number of spores—therefore limiting impact on non-target species such as natural enemies—but with a sufficient incubation period to allow transmission from mass-reared insects to wild conspecifics (Leite et al. 2022). A comparison of different inoculation methods is also provided and is interesting from a methodological point of view for future studies or even large-scale applications.</p> <p>Using a well-designed experimental setup, the authors show that high pathogenicity (measured by LD50) is achievable even at low spore doses and independently of the fly's sex. Lethal action speed was, however, dependent on the dose. Regarding temperature, the authors demonstrated that mycelium growth was affected by the mean temperature but, most importantly, by daily fluctuation regimes; night and day temperature alternation allowed faster growth than constant temperature. These notions of thermal fluctuations are still under-researched in terms of their modulating role in biological control yet seem central to understanding them, as the authors demonstrate here. The correlation between increased virulence and specific abiotic factors, such as temperature, offers valuable additional insights into the bioecology of the insect host and the fungal pathogen. Chailleux et al. finally point out the need for careful selection of adjuvants in formulations and pay attention to interactions with the abiotic environment to avoid compromising the effectiveness of biological control agents. Indeed, the survival rate of inoculated flies increased in the presence of the corn starch adjuvant, but this effect decreased with temperature. As corn starch unexpectedly delayed mortality, the authors suggest a potential for enhancing conspecific transmission</p> <p>From a broader perspective, the study emphasizes the importance of standardizing virulence evaluation to optimize biological control strategies like auto-dissemination or vectoring with sterile males, particularly in field conditions. The study contributions are timely and essential for advancing sustainable pest management strategies and improving inoculation methods. The findings underscore the need for field trials to refine these strategies, particularly in Africa, where climatic factors may affect pathogen efficacy and fly behavior.

Understanding parasite exposure and how resistance is maintained over time are therefore of key importance for defining efficient management strategies. To date, the role wildlife play in these dynamics has been poorly studied. The work of Beaumelle et al. examine this essential question by studying the transmission dynamics of nematodes at the environmental interface between transhumant sheep and wild ungulates, more specifically with ibex (Capra ibex) that allochronically share alpine pastures when sheep are brought to graze in summer. By collecting fresh fecal material from both species and using a metabarcoding approach based on ITS-2 sequences, the authors characterise the nemabiome in each ungulate species and demonstrate that the two host species share a large portion of their parasite diversity. More importantly, by focusing on a gene (β-tubulin isotype 1) associated with resistance to a commonly used anthelmintic drug (benzimidazole), they demonstrate that both species carry resistant nematode strains, but that the diversity of strains, and particularly susceptible strains, is much higher in ibex. A key feature of the sampling design is that fecal material from both species was collected before seasonal transmission between the ungulate species could occur. Therefore, their results demonstrate that ibex are able to maintain resistant strains over long periods of time and therefore may be major nematode reservoirs for sheep infection. This important conclusion raises a series of key questions. How are resistant genotypes maintained in untreated ibex hosts? Is the cost of resistance so weak that they can coexist with susceptible strains in the absence of drug treatment or does anthelminthic contamination of the pastures maintain resistant genotypes directly in wild hosts? This work also opens several interesting perspectives: For example, what additional resistant parasites may be maintained by these wildlife hosts? What role do other wild ungulate species play in the evolution of nematode communities in transhumant sheep? An expansion of this work to the larger community of wild ungulates using alpine pastures, and an evaluation of the degree to which wild species are exposed to anthelminthic drugs released by grazing livestock into the environment is now required to understand the deeper consequences of drug treatment for shaping parasite communities and their cascading impacts for wildlife conservation, and the development of efficient and sustainable management strategies for pastoral livestock.&nbsp;</p> <p style="text-align: justify;"><strong>References</strong></p> <p>Beaumelle et al.

With more than 380 million entomological specimens already preserved in museums (Johnson and Owens 2023), there is much work left to document what we already have. Fortunately, new advances in DNA sequencing have given us the opportunity to get enormous amounts of information from dried specimens on pins.<br>&nbsp;<br>One such advance is HyRAD-X, which uses RAD-derived probes originally developed using RNA extracted from a selection of specimens with high RNA-integrity (Schmid et al. 2017). These exome-limited probes can then be used to capture low-integrity DNA extracted from a single leg from museum specimens, followed by Illumina sequencing of the enriched libraries.<br>&nbsp;<br>Ground beetles allow an excellent demonstration of this approach, as their diversity, large size, and charismatic appearance has led to them being well represented in museums. Using a HyRAD-X probe set previously developed for a higher phylogeny within the subfamily Carabinae (Toussaint et al. 2021), the authors have now applied the same probe set to produce a comprehensive phylogeny for Arcifera, a clade of four subgenera and ten species within the genus Carabus (Pauli et al. 2024).<br>&nbsp;<br>Of the 96 specimens that they started out with, 90% were from natural history collections and 40% dropped out immediately due to poor DNA extraction yield. After filtering the resulting sequence reads for minimum coverage and minimum number of samples per locus, they ended up with 35 museum specimens with an average of 793 loci. Phylogenetic analysis of this data supported the current classification of these beetles.<br>&nbsp;<br>Pauli et al’s. (2024) study has effectively shown the power of HyRAD-X methods for applications at the species level.

However, such large and extravagant morphological structures are expected to come at a cost, potentially imposing trade-offs with life history traits, physiological functions, or certain behaviors (Emlen, 2001; Emlen, 2008). These costs should be manageable only by males in the best condition. The present study by Blackwell et al. (2024) examines this assumption through a comprehensive study on the European earwig, where males possess forceps-like cerci that vary widely in size within populations.</p> <p style="text-align: justify;">In the European earwig (<em>Forficula auricularia</em>), male forceps are used in male-male contests as weapons to deter competitors prior to mating (Styrsky &amp; Rhein, 1999) or to interrupt mating pairs by non-copulating males (Forslund, 2000; Walker &amp; Fell, 2001). Despite providing benefits in terms of mating success (Eberhard &amp; Gutierrez, 1991; Tomkins &amp; Brown, 2004), it remains unknown whether long or short forceps are associated with other important life-history traits.</p> <p style="text-align: justify;">In this laboratory study, Blackwell et al. (2024) investigated two European earwig populations, each divided into two subpopulations: one with the shortest forceps and one with the longest forceps. They examined the potential costs of long forceps on six different traits: one reproductive trait (sperm storage); three non-reproductive behavioral traits such as locomotor performance (involved in search for resources), fleeing reaction face to a risk (long forceps are supposed to be correlated with boldness), and aggregation behavior (European earwigs are facultative group-living organisms); and survival (when deprived of food and subsequently when exposed to an entomopathogenic fungus).</p> <p style="text-align: justify;">As males in the best condition are supposed to be those that can afford to develop large forceps, Blackwell et al. (2024) predicted that males with long forceps would perform better than those with short forceps across the investigated traits. However, their predictions were not validated, as no correlation between weapon size and male quality was detected in either population. Although the sample size is sometimes limited, the consistency of these results across different populations adds robustness to their conclusions.</p> <p style="text-align: justify;">By demonstrating that forceps length in the European earwig does not reliably indicate male quality, this paper challenges existing theories and highlights the complexity of evolutionary processes shaping morphological traits. Furthermore, the study raises important questions about the evolutionary mechanisms maintaining weapon size diversity, providing a fresh perspective that could stimulate further research and debate in the field, notably the search for other traits where costs might be incurred.</p> <p style="text-align: justify;"><strong>References</strong></p> <p style="text-align: justify;">Blackwell, S.E.M., Pasquier, L., Dupont, S., Devers, S., Lécureuil, C. &amp; Meunier, J.

In this sense, this study presented a valuable contrast that shows interesting results about the higher richness and lower abundance of the biota of the American tropics, even with a small sample, in comparison with the biota of the African tropics. The results are supported mainly by the rarefaction curves shown. This pattern of higher species richness and lower specimen abundance, observed in other American tropical taxa such as trees, birds, or butterflies, is observed too in these parasitoid wasps, increasing the body of information that could support the extension of the pattern to the entire biota of the American tropics. The authors recognize the study's limitations, which include strong differences in the size of the forest coverture between places.

Assessing the vulnerability of species and predicting their response to future changes has become a priority for environmental biology (Williams <em>et al. </em>2020).</p> <p style="text-align: justify;">Over the last few decades, oxygen concentrations in both the open ocean and coastal waters have been declining steadily as the result of multiple anthropogenic activities. This global trends towards hypoxia is expected to continue in the future, causing a host of negative effects on marine ecosystems. Oxygen is indeed crucial to many biological processes in the ocean, and its decrease could have strong impacts on biogeochemical cycles, and therefore on marine productivity and biodiversity (Breitburg <em>et al. </em>2018).</p> <p style="text-align: justify;">Whenever facing such drastic environmental changes, all organisms are expected to have some intrinsic ability to adapt. At shorter than evolutionary timescales, ecological plasticity and the eco-physiological processes that sustain it could constitute important adaptive mechanisms (Williams <em>et al.</em> 2020)</p> <p style="text-align: justify;">Marine sponges seem particularly well-adapted to oxygen deficiency, as some species can survive seasonal anoxia for several months. This paper by Strehlow <em>et al. </em>(2023) examines the mechanisms allowing this exceptional tolerance. Focusing on two species of sponges, they used transcriptomics to assess how gene expression by sponges, by their mitochondria, or by their unique and species-specific microbiome could facilitate this trait. Their results suggest that sponge holobionts maintain metabolic activity under anoxic conditions while displaying shock response, therefore not supporting the hypothesis of sponge dormancy. Furthermore, hypoxia and anoxia seemed to influence gene expression in different ways, highlighting the complexity of sponge response to deoxygenation. As often, their exciting results raise as many questions as they provide answers and pave the way for more research regarding how anoxia tolerance in marine sponges could give them an advantage in future oceanic environmental conditions.</p> <p style="text-align: justify;"><strong>References</strong></p> <p style="text-align: justify;">Breitburg <em>et al. </em>(2018): Declining oxygen in the global ocean and coastal waters. <em>Science </em>359, eaam7240. <a href="https://doi.org/10.1126/science.aam7240&nbsp;" target="_blank" rel="noopener">https://doi.org/10.1126/science.aam7240&nbsp;</a></p> <p style="text-align: justify;">Strehlow <em>et al.</em> (2023): Transcriptomic responses of sponge holobionts to in situ, seasonal anoxia and hypoxia. bioRxiv, 2023.02.27.530229, ver. 4 peer-reviewed and recommended by Peer Community in Zoology. &nbsp;<a href="https://doi.org/10.1101/2023.02.27.530229&nbsp;" target="_blank" rel="noopener">https://doi.org/10.1101/2023.02.27.530229&nbsp;</a></p> <p style="text-align: justify;">Williams <em>et al.</em> (2008) Towards an Integrated Framework for Assessing the Vulnerability of Species to Climate Change. <em>PLOS Biology</em> 6(12): e325. <a href="https://doi.org/10.1371/journal.pbio.0060325" target="_blank" rel="noopener">https://doi.org/10.1371/journal.pbio.0060325</a>&nbsp;</p> <p style="text-align: justify;">Williams <em>et al.</em> (2020): &nbsp;Research priorities for natural ecosystems in a changing global climate. <em>Global Change Biology</em> 26: 410–416. <a href="https://doi.org/10.1111/gcb.14856&nbsp;" target="_blank" rel="noopener">https://doi.org/10.1111/gcb.14856&nbsp;</a></p> </div> </span> <div> <a href="/articles/rec?id=211" class="btn btn-success pci-public pci-smallBtn" > More </a> </div> </div> </div> </div> </td><td>Transcriptomic responses of sponge holobionts to in situ, seasonal anoxia and hypoxia</td><td>Brian W Strehlow, Astrid Schuster, Warren R Francis, Lisa Eckford-Soper, Beate Kraft, Rob McAllen, Ronni Nielsen, Susanne Mandrup, Donald E Canfield</td><td>&lt;p&gt;Deoxygenation can be fatal for many marine animals; however, some sponge species are tolerant of hypoxia and anoxia.

Host manipulation is increasingly acknowledged as a pervasive adaptive transmission strategy employed by parasites, and as such is one of the most remarkable manifestations of the extended phenotype (Dawkins, 1982).</p> <p style="text-align: justify;">In this laboratory study, Rigaud et al. (2023) delved into the time course of antipredator behavioral modifications induced by the acanthocephalan P<em>omphorhynchus laevis</em> in its amphipod intermediate host <em>Gammarus pulex</em>. This system has a good foundation of prior knowledge (Bakker et al., 2017; Fayard et al., 2020; Perrot-Minnot et al., 2023), nicely drawn upon for the present work. This parasite orchestrates a switch from predation suppression, during the noninfective phase, to predation enhancement upon maturation. Specifically, <em>G. pulex</em> infected with the non-infective acanthella stage of the parasite can exhibit increased refuge use and reduced activity compared to uninfected individuals (Dianne et al., 2011, 2014), leading to decreased predation by trout (Dianne et al., 2011). In contrast, upon reaching the infective cystacanth stage, the parasite can enhance the susceptibility of its host to trout predation (Dianne et al., 2011).</p> <p style="text-align: justify;">The present work aimed to understand the temporal sequence of these behavioral changes across the entire ontogeny of the parasite. The results confirmed the protective role of <em>P. laevis </em>during the acanthella stage, wherein infected amphipods exhibited heightened refuge use. This protective manipulation, however, became significant only later in the parasite's ontogeny, suggesting a delayed investment strategy, possibly influenced by the extended developmental time of <em>P. laevis</em>. The protective component wanes upon reaching the cystacanth stage, transitioning into an exposure strategy, aligning with theoretical predictions and previous empirical work (Dianne et al., 2011; Parker et al., 2009). The switch was behavior-specific. Unlike the protective behavior, a decline in the amphipod activity rate manifested early in the acanthella stage and persisted throughout development, suggesting potential benefits of reduced activity for the parasite across multiple stages. Furthermore, the findings challenge previous assumptions regarding the condition-dependency of manipulation, revealing that the parasite-induced behavioral changes predominantly occurred in the presence of cues signaling potential predators. Finally, while amphipods infected with acanthella stages displayed survival rates comparable to their uninfected counterparts, increased mortality was observed in those infected with cystacanth stages.</p> <p style="text-align: justify;">Understanding the temporal sequence of host behavioral changes is crucial for deciphering whether it is adaptive to the parasite or not. This study stands out for its meticulous examination of multiple behaviors over the entire ontogeny of the parasite highlighting the complexity and condition-dependent nature of manipulation. The protective-then-expose strategy emerges as a dynamic process, finely tuned to the developmental stages of the parasite and the ecological challenges faced by the host. The delayed emergence of protective behaviors suggests a strategic investment by the parasite, with implications for the host's survival and the parasite's transmission success. The differential impact of infection on refuge use and activity rate further emphasizes the need for a multidimensional approach in studying parasitic manipulation (Fayard et al., 2020). This complexity demands further exploration, particularly in deciphering how trophically-transmitted parasites shape the behavioral landscape of their intermediate hosts and its temporal dynamic (Herbison, 2017; Perrot-Minnot &amp; Cézilly, 2013). &nbsp;As we discover the many subtleties of these parasitic manipulations, new avenues of research are unfolding, promising a deeper understanding of the ecology and evolution of host-parasite interactions.</p> <p style="text-align: justify;"><strong>References</strong></p> <p>Bakker, T.

This axis represents the variation in a continuum of life-history strategies, from fast-reproducing short-lived species to slow-reproducing long-lived species. The pace-of-life axis has been the focus of much research largely in mammals, birds, reptiles and plants but less so in invertebrates (Salguero-Gómez et al. 2016; Araya-Ajoy et al. 2018; Healy et al. 2019; Bakewell et al. 2020). Outcomes from this research have highlighted variation across taxa on this axis and mixed support for, and against, patterns expected of the pace-of-life continuum. Given this, a greater understanding of the variation of the pace-of-life across-, and within, taxa are needed. Indeed, Guicharnard et al. (2023) highlight several points regarding our broader understanding of pace-of-life. In general, invertebrates are poorly represented, the variation of pace-of-life across taxonomic scales is less well understood and the relationship between pace-of-life and dispersal, a key life history, requires more attention. Here, Guicharnard et al. (2023) provide a first attempt at addressing the relationship between dispersal and pace-of-life at different scales.</p> <p style="text-align: justify;">The authors, under controlled conditions, investigated how life-history traits and effective dispersal covary for 28 lines from five species of endoparasitoid wasps from the genus Trichogramma. At the species level negative correlations were found between development time and fecundity, matching pace-of-life axis predictions. Although this correlation was not found to be significant among lines, within species, a similar pattern of a negative correlation was observed. This outcome matches previous findings that consistent pace-of-life axes become more difficult to find at lower taxonomic levels. Unlike the other life-history traits measured, effective dispersal showed no evidence of differences between species or between lines. The authors also found no correlation between effective dispersal and other-life history traits which suggests no dispersal/life-history syndromes in the species investigated. One aspect that was not assessed was the impact of density dependence on pace-of-life and effective dispersal, largely as this was a first step in assessing relationship of dispersal with pace-of-life at different scales. However, the authors do acknowledge the importance of future studies incorporating density dependence and that such studies could potentially lead to more generalizable understanding of pace-of-life and dispersal within Trichogramma.</p> <p style="text-align: justify;">A pleasant addition was the link to potential implications for biocontrol. This addition showed an awareness by the authors of how insights into pace-of-life can have an applied component. The results of the study highlighted that selecting for specific lines of a species, to maximise a trait of interest at the cost of another, may not be as effective as selecting different species when implementing biocontrol. This is especially important as often single, established species used in biocontrol are favoured without consideration of the potential of other species which can lead to more efficient biocontrol. &nbsp; &nbsp;</p> <p><strong>REFERENCES</strong></p> <p>Araya-Ajoy, Y.G., Bolstad, G.H., Brommer, J., Careau, V., Dingemanse, N.J. &amp; Wright, J.
