VenomsBase will unify venom datasets, standardize terminology, and enable comparative analyses across species, facilitating novel toxin discovery and functional annotation. Key features of VenomsBase include user-friendly data submission modules with built-in validation, advanced cross-species analysis tools, and integration of multidisciplinary datasets spanning genomics, transcriptomics, proteomics, functional assays, and ecological metadata. A modular, cloud-based design will ensure scalability, while heuristic scoring systems will guide users toward high-confidence data entries. To promote accessibility, the envisioned VenomsBase will provide tutorials, regular training sessions, case studies, and feedback loops, supporting researchers at all levels. By harmonizing venom research and addressing the limitations of outdated or nonstandardized methods, VenomsBase aims to revolutionize the field, while being continuously improved and refined by venom experts. This initiative will unlock venoms' potential to make groundbreaking discoveries, address global health challenges, and foster collaboration and innovation across the scientific community.</p>","PeriodicalId":13666,"journal":{"name":"Integrative Organismal Biology","volume":"7 1","pages":"obaf026"},"PeriodicalIF":2.2,"publicationDate":"2025-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12259279/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144636948","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Zoea 1, the first planktonic stage, showed higher metabolic rates than zoea 2, likely due to a greater proportion of metabolically inactive tissue and differing energy sources (egg reserves vs. exogenous feeding). From megalopa to benthic juvenile stages, metabolic rates increased exponentially, probably reflecting increased organ complexity and activity. However, rates declined significantly from 7-month-old juveniles to adults, potentially due to reduced growth, longer intermolt periods, and behavioral adaptations. Among adults, males exhibited metabolic rates twice as high as females, likely linked to greater territorial and reproductive activity.

Many tropical anurans lay terrestrial eggs that are particularly vulnerable to drying and warming. In some such species, embryos hatch prematurely to escape from drying eggs. In red-eyed treefrogs, <i>Agalychnis callidryas</i>, embryos hatch early to escape both drying and excessive warming, expressing a behavioral thermal tolerance (i.e., VT<sub>Max</sub>). Prior research suggested that drying reduces the VT<sub>Max</sub> of embryos. However, because hydrated clutches warmed more slowly, the effect of drying on VT<sub>Max</sub> was confounded with that of faster warming. To disentangle these dynamics, we designed a novel apparatus to warm terrestrial frog egg-clutches at controlled rates and minimize evaporative cooling. We independently manipulated clutch hydration and heat input to assess their individual and combined effects on embryo VT<sub>Max</sub>. Proportional egg-volume loss was similar across hydration × heat input categories. High heat input resulted in higher clutch warming rates and shorter trial durations, across hydration levels. Within clutches, warming rates differed between back and surface thermocouple positions, generating thermal gradients as warming progressed. Clutch dehydration reduced embryo VT<sub>Max</sub>, with no main or interacting effect of heat input. This evidence that egg drying reduces thermal tolerance across testing conditions supports a direct role for hydration in the behavioral decisions of warming embryos, rather than an indirect effect mediated by changes in evaporative cooling. It suggests that embryos assessing risk integrate information about hydration, and perhaps changes in hydration, with information about current and changing temperature. These findings highlight the value of methods to independently manipulate hydration and heating rate, showing the complexity of thermal ecology in embryonic ectotherms. We encourage further research on temperature and hydration effects on embryo hatching to better understand tropical anurans' adaptive strategies under climate change.</p>","PeriodicalId":13666,"journal":{"name":"Integrative Organismal Biology","volume":"7 1","pages":"obaf023"},"PeriodicalIF":2.2,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12257936/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144636949","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Much of the previous literature on this topic focuses on whole-animal metabolic rates and corresponding cellular and molecular mechanisms that enable these birds to withstand the demands of changing environmental conditions. Basal and maximal shivering metabolic rates, as well as daily energy expenditure, typically increase in winter for small birds overwintering in cold climates, which might increase the production of reactive oxygen species (ROS) within mitochondria as a natural byproduct of aerobic metabolism. In this study, we measured summer to winter differences in oxidative balance in four species of resident passerine birds. Blood samples were taken from field-collected American goldfinch (<i>Spinus tristis)</i>, black-capped chickadee (<i>Poecile atricapillus</i>), house finch (<i>Haemorhous mexicanus</i>), and house sparrow (<i>Passer domesticus</i>) during the summer and winter of 2023-2024 in South Dakota, USA. We determined plasma total antioxidant capacity and lipid oxidative damage, and red blood cell activities of three antioxidant enzymes: catalase (CAT), glutathione peroxidase (GPx), and superoxide dismutase (SOD). Lipid oxidative damage was significantly lower in winter for three of four species, and total antioxidant capacity for all species was significantly lower in winter compared with summer. Across all species, CAT activity was significantly higher in summer than in winter. In contrast, SOD activity was significantly higher in winter than in summer for all species. We also found species-level differences across the two seasons. These data suggest that the higher thermoregulatory costs in winter do not result in consistently elevated oxidative damage or antioxidant capacities relative to summer in small resident birds in cold climates, despite previously demonstrated winter increases in metabolic rates and energy expenditure. Such a result might occur as a function of either a reduction in dietary antioxidants and/or uncoupling of ROS production and metabolism in winter relative to summer or may be related to oxidative costs associated with reproduction.</p>","PeriodicalId":13666,"journal":{"name":"Integrative Organismal Biology","volume":"7 1","pages":"obaf024"},"PeriodicalIF":2.2,"publicationDate":"2025-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12138340/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144234004","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One key function of latex is to seal, but the most crucial necessities for wound sealing differ by the environment. For species growing in arid climates, for example, minimizing water loss is crucial whereas in tropical ecosystems a strong (chemical) defense against herbivores, parasites, and germs is of more imminent importance.

Animals that use this strategy have diverse methods of finding each other, organizing behaviors, and capturing prey. There is wide variation in the extent to which these behaviors are coordinated and in the stability of individual roles. This study characterizes social predation by the nudibranch mollusc, <i>Berghia stephanieae</i>, which is a specialist predator that eats only the sea anemone, <i>Exaiptasia diaphana</i>. A combination of experimental and modeling approaches established that <i>Berghia</i> consistently preys upon <i>E. diaphana</i> in groups, even when resources are abundant. However, this preference for social foraging does not appear to be a fixed personality trait, as individuals did not exhibit stable roles such as leader or follower. Instead, the population exhibited fission-fusion dynamics with temporary roles during predation. The extent of this social feeding was not altered by length of food deprivation, suggesting that animals are not shifting strategies based on hunger state. Furthermore, classic gastropod cues-such as slime trails, attraction to injured anemones, or preference for conspecifics feeding-did not facilitate group formation. Thus, <i>Berghia</i> provides an example of a specialist predator of dangerous prey that loosely organizes social feeding, independent of hunger state and fixed individual roles, while the mechanism of aggregation remains unknown.</p><p><strong>Significance statement: </strong>Social predation is an adaptive strategy that enables predators to subdue dangerous prey while minimizing injury. Many nudibranchs specialize to predate upon cnidarians, which pose unique challenges due to their potent defenses. Although nudibranchs are often characterized as solitary hunters, our study reveals that <i>Berghia stephanieae</i> exhibits social predation behaviors, forming temporary, fluid groups to feed on sea anemones. These groups lack stable social structures, with individuals adopting temporary roles such as joining or initiating feeding. Interestingly, we found no evidence that aggregation is driven by simple cues such as slime trails, conspecific activity, or prey injury, suggesting that group formation may depend on more complex or context-specific mechanisms.
