Abstract Sexual selection, one of the central pillars evolutionary theory, has powerful effects on organismal morphology, behaviour and population dynamics. However, current knowledge about geographical variation in this mechanism its underlying drivers remains highly incomplete, part because standardized data strength sexual selection is sparse even for well-studied organisms. Here we use information mating systems – including incidence polygamy extra-pair paternity to quantify intensity 10671 (>99.9%) bird species distributed worldwide. We show that avian varies latitudinally, peaking at higher latitudes, although gradient reversed world’s most sexually selected birds specialist frugivores which are strongly associated with tropical forests. Phylogenetic models further reveal explained by temperature seasonality coupled a suite climate-associated factors, migration, diet, territoriality. Overall, these analyses suggest climatic conditions leading short, intense breeding seasons, or abundant patchy food resources, increase potential birds, driving latitudinal gradients selection. Our findings help resolve longstanding debates spatial mechanisms linked reproductive biology, provide comprehensive species-level dataset studies phenotypic evolution context global change.

Biodiversity can increase in both high‐ and low‐connected landscapes. However, we lack predictions related to biodiversity dynamics when accounting for the temporal heterogeneity connections among habitats of a landscape. Here, study relationship between fluctuations landscape connectivity at local regional scales. We contrast about species richness landscapes with without connectivity.

Interpreting sound gives powerful insight into the health of ecosystems. Beyond detecting presence wildlife, bioacoustic signals can reveal their behavior. However, behavioral information is underused because identifying function and context animals' sounds remains challenging. A growing acoustic toolbox allowing researchers to begin decoding by linking individual population-level sensing. Yet, studies integrating tools for across levels biological organization remain scarce. We aim catalyze emerging field bioacoustics synthesizing recent successes rising analytical, logistical, ethical challenges. Because behavior typically represents first response environmental change, we posit that will provide theoretical applied insights adaptations global change.

Species distributions are frequently modeled using predictors that exceed the spatial scale experienced by focal species. Incorporating fine-scale environmental conditions is therefore expected to lead more realistic model predictions. However, importance of existing local heterogeneity on species distribution remains poorly assessed although can effectively utilize multiple microhabitats for behavioral adaptation withstand climate change impacts. Here, we developed a fine-resolution based ambient air northern pika ( Ochotona hyperborea ), small lagomorph found in rocky landforms, Hokkaido, Japan, first understand improvement performance from conventional coarse-resolution model. We then how predictions alter incorporating rock-interstice microclimates their habitats baseline (1981–2010) and future periods (2041–2100). The performed better overall predicted lower habitat suitability across study area than Incorporation microclimate increased markedly relative thermal conditions, which resulted predicting suitable areas (hotter) elevations remaining into future. This result suggests may negative impacts rising temperatures utilizing rock interstices via adaptation.

Abstract Understanding how human-mediated environmental change affects biodiversity is key for conserving evolvability. Because the most severe impacts are ongoing, such an understanding proving exceptionally difficult to attain. Islands natural, replicated experiments that serve as proxies habitat fragmentation and, therefore, allow us use historical changes in under Island Biogeography Theory (IBT) predict consequences of immediate anthropogenic on functional trait evolution. Rattlesnake venoms molecular phenotypes mediate interactions with prey, and diet venom complexity positively correlated. Consequently, rattlesnake investigate traits co-vary according IBT. We collected from 83 rattlesnakes across multiple species 11 islands Gulf California estimated using Shannon Diversity Index. Using a mixed effects modeling approach, we found number congenerics, island isolation, area best predicted variability. All variables exhibited negative relationship complexity, contrary predictions Larger more congenerics reduced perhaps reflecting niche partitioning specialization.
