Anthropogenic climate change is projected to become a major driver of biodiversity loss, destabilizing the ecosystems on which human society depends. As planet rapidly warms, disruption ecological interactions among populations, species and their environment, will likely drive positive feedback loops, accelerating pace magnitude losses. We propose that, even without invoking such amplifying feedback, loss should increase nonlinearly with warming because non-uniform distribution biodiversity. Whether these non-uniformities are uneven populations across species’ thermal niche, or niche limits within an community, we show that in both cases, resulting clustering population tolerances drives nonlinear increases risk discuss how fundamental constraints physiologies geographical distributions give rise clustered tolerances, responses changing climates could variously temper, delay intensify dynamics. argue risks be null expectation under warming, highlight empirical research needed understand causes, commonness consequences better predict where, when why losses occur.

La Graciosa, a Natura 2000 site in the Canary Islands, faces substantial conservation challenges, including large free-roaming cat population that threatens island’s native biodiversity. In July 2024, Trap–Neuter–Return (TNR) campaign achieved an 81.4% sterilization rate within urban areas, highlighting TNR’s short-term effectiveness reducing reproductive potential and, consequently, mitigating predation pressures primarily through prevention of new litters and reduced activity cats. The campaign’s success relied heavily on active involvement local community, who assisted with identifying, trapping, monitoring cats, thereby facilitating high rate. However, administrative restrictions hindered access to peri-urban zones, leaving essential clusters unsterilized limiting overall scope. Additionally, strong opposition from groups, amplified by extensive media coverage, halted project prematurely, effective 69.3% three months. Population Viability Analysis (PVA) suggests achieving rates could lead reduction over time; however, inability all segments reach ideal 93–95% threshold limits as long-term standalone solution. Our findings underscore need for adaptive, context-specific management frameworks ecologically sensitive areas integrate TNR complementary measures, consider regulatory barriers, value community involvement. This case study provides crucial insights policymakers conservationists seeking balance biodiversity humane practices protected areas.

Real-time biodiversity monitoring should provide more resolved data to quantify shifts in ecological communities progressively altered by anthropogenic disturbances. Identifying trends requires a rapid and efficient inventory method that enables the collection delivery of high-resolution within short intervals. Using aquatic environmental DNA (eDNA), we investigated spatiotemporal changes fish mammal along Maroni River French Guiana. We compared spatial between two years, separated four-year interval, during which an increase disturbances was observed. To evaluate changes, examined impact these on both taxonomic functional diversity. Our findings revealed that, while did not result major decline, it continued drive alterations community richness.

Given that many species are threatened by human activities, understanding wildlife responses to land use changes is crucial for effective biodiversity conservation. Quantifying diversity from multiple dimensions provides a more comprehensive of community dynamics, such as insights into functional and phylogenetic diversity, which capturing the full complexity bird communities. In this study, we surveyed communities in Southern Anhui Mountainous Area across four seasons, including two human-dominated types (farmland village) one natural landscape (forest). Variations taxonomic, functional, uses seasons were analyzed, with focus on assembly processes. Our results showed that, during spring summer, supported higher richness all (taxonomic, phylogenetic) compared landscapes (H2,168 > 25, p < 0.001). However, due influence migratory birds, villages exhibited lowest taxonomic evenness = 8.31, 0.016), while had lower 31.27, autumn winter, no significant differences or observed between (H2,42 5.72, 0.05).

Biodiversity is experiencing an unprecedented crisis, with intensifying global aridity representing a critical driver of species extinction. However, the extent to which species' preferences for specific conditions and their tolerance range influence vulnerability remains poorly understood. Using data from 5558 passerine bird species, we examined how niche affects current projected extinction risks whether these relationships are influenced by other ecological life-history traits altering persistence. Bayesian models revealed significant impacts position breadth on both risks, effects varying according traits. Overall, interacted wider risk than risk, indicating broader array requiring conservation attention in future. Our results identified three key groups: (1) preferring humid conditions, (2) confined arid zones small clutch sizes, (3) narrow low habitat breadth, short generation length, omnivorous diet, full migrant strategy. By identifying birds most at our study offers insights prioritizing actions, guiding geographic focus identification more under ongoing climate change.
