This study synthesizes data from over 100 ectotherms to reveal that while heat tolerance (CTmax) generally correlates with thermal performance traits, the relationship varies by physiological process and timescale, suggesting that relying solely on CTmax may overestimate thermal safety margins for critical metabolic functions.
This study reveals that the brood cells of the solitary oil-collecting bee *Centris aethyctera* harbor highly structured and compartmentalized microbial communities, including diverse antibiotic-producing bacteria and potential pathogen-defending fungi, which collectively form a specialized antimicrobial microenvironment shaped by maternal provisioning and environmental acquisition.
By employing a global, species-resolved machine-learning approach, this study reveals that the widely studied *Gephyrocapsa huxleyi* contributes only about 7% of global coccolithophore calcium carbonate stocks, demonstrating that a diverse assemblage of other species, rather than this single species, underpins marine CaCO3 cycling.
This study analyzes the ecomorphological traits and foraging behaviors of Mediterranean passerines to demonstrate how specific adaptations, such as wider gapes and faster digestive transit rates, distinguish frugivorous and seed-dispersing species and shape plant-frugivore interaction networks in Iberian ecosystems.
This study challenges the assumption that lions uniformly utilize all waterholes based solely on prey abundance or catchability, revealing instead that visitation patterns are driven by a complex interplay of territorial waterhole density, habitat openness, social interactions, and an evolutionary "shell-game" strategy that prioritizes unpredictability over simple resource optimization.
This study reveals that three sympatric *Caenorhabditis* nematodes in southwestern Germany exhibit differential phoretic vector use, with the newly described *C. apta* showing a particularly strong and specific association with invasive nitidulid beetles, especially *Stelidota geminata*, thereby providing evidence for group dispersal and establishing a foundation for understanding nematode-vector interactions.
By integrating large-scale conventional tagging data with direct acoustic telemetry observations within a statistical framework, this study demonstrates that post-release survival of gag reef fish declines with capture depth due to barotrauma, providing refined annual and seasonal survival estimates to improve fisheries management.
Contrary to the prevailing assumption that zoonotic pathogens have minimal impact on their wildlife reservoirs, a three-year field experiment revealed that Puumala hantavirus infection significantly reduces the survival of young bank voles in natural settings.
This study demonstrates that in the Eastern Himalayas, dietary specialization drives elevational migration in mountain birds, with specialists tracking seasonal insect abundance downslope while generalists remain at high elevations by shifting to fruit and nectar during winter.
Although both the Gulf of Mexico and the eastern Indian Ocean feature warm, stratified waters dominated by cyanobacteria, the latter supports significantly higher tuna spawning productivity due to enhanced nutrient inputs and a more efficient food web structure that shortens energy pathways to larval tuna through distinct zooplankton grazing dynamics.
This study reveals that while shallow *Porites astreoides* corals can acclimate to deeper conditions through plasticity, mesophotic corals fail to survive upward transplantation, thereby challenging the notion that deep reefs serve as universal climate refugia for shallow populations.
This study evaluates the reliability of acoustic indices for biodiversity monitoring across a subtropical region, revealing that while these indices correlate better with animal abundance and community diversity than species richness, their significant spatiotemporal autocorrelation necessitates adjusted sampling designs and statistical approaches for effective application.
This study demonstrates that despite distinct regional evolutionary histories in the Amazonian Andes and Guiana Shield, Ithomiini butterfly communities exhibit consistent elevational diversity patterns driven by local habitat filtering and biotic interactions acting upon regionally distinct species pools.
This study reveals that the maintenance cost of photosynthesis, driven by accelerated PSII turnover at high irradiance, imposes a key energetic constraint that defines an optimal depth range for zooxanthellate corals by balancing photosynthetic capacity against repair costs, thereby providing a mechanistic framework to predict their depth distributions under environmental change.
This study reveals that despite global conservation targets like 30x30, marine protected areas within national waters provide critically insufficient no-take coverage for threatened sharks and rays, with 79% of threatened species having less than 1% of their range protected and significant data gaps further obscuring the true extent of meaningful protection.
This study demonstrates that uncontrolled goat overgrazing in Ecuador's Tumbesian dry forest drives a directional loss of ant taxonomic and functional diversity, causing community homogenization through habitat filtering that disproportionately eliminates specialist and soil-dwelling guilds while favoring opportunistic species.
A two-phase transplant experiment reveals that the northward expansion of invasive *Reynoutria japonica* in Europe is limited not by adaptive differentiation or transgenerational effects, but by low temperatures and short growing seasons that reduce essential below-ground biomass accumulation required for overwintering.
This study demonstrates that while glyphosate-tolerant Roundup Ready soybeans appear metabolically indistinguishable from non-GM counterparts under simplified conditions, their unique metabolic reprogramming and negative impacts on the virus vector *Epilachna varivestis* only become apparent when exposed to complex, realistic multi-species stress involving rhizobacteria and viral infection.
This study reveals that leopards on Namibian farmlands select resting and kill sites primarily based on rugged terrain and concealment rather than avoiding human infrastructure, highlighting their ability to coexist with people by remaining hidden.
This study demonstrates that high-intensity sheep grazing significantly impoverishes soil seed bank density and diversity in sand grasslands compared to cattle grazing, indicating that livestock type is a critical factor in conservation management.
