Abstract Seasonal migration is intrinsically connected to the balance of survival and reproduction, but whether migratory behavior influences species’ position on slow-fast continuum life history poorly understood. We found that boreal-breeding birds migrate long distances exhibit higher annual adult lower reproductive investment relative co-distributed boreal species shorter winter closer their breeding grounds. Our study uses “vital rates” data output survivorship compiled from literature for a assemblage 45 mostly passerine birds. These breed sympatrically in North American forests diversity environments northern winter. After controlling body size phylogeny, distance apparent are positively related across species. Both correlated with wintering warmer, wetter, greener. At same time, longer migrations associated reduced time spent grounds, clutch sizes, fecundity (clutch × maximum number broods per year). Although seasonal often high mortality, our results suggest long-distance imposes selection pressures both confer demand rates. That is, owing cost migration, this strategy can only persist if balanced by survival. supports idea evolves promote environments. In birds, evolution longest yields highest survival, at an inherent fecundity. therefore reveal as fundamental axis predicts, inextricable from, reproduction.

As human density increases, biodiversity must increasingly co-exist with urbanization or face local extinction. Tolerance of urban areas has been linked to numerous functional traits, yet few globally consistent patterns have emerged explain variation in tolerance, which stymies attempts at a generalizable predictive framework. Here, we calculate an Urban Association Index (UAI) for 3,768 bird species 137 cities across all permanently inhabited continents. We then assess how this UAI varies as function ten species-specific traits and further test whether the strength trait relationships vary three city-specific variables. Of nine were significantly associated tolerance. Urban-associated tend be smaller, less territorial, greater dispersal ability, broader dietary habitat niches, larger clutch sizes, longevity, lower elevational limits. Only bill shape showed no global association Additionally, several varied latitude and/or population density. For example, associations body mass diet breadth more pronounced higher latitudes, while territoriality longevity reduced Thus, importance filters birds predictably cities, indicating biogeographic selection tolerance that could prior challenges search patterns. A informed framework predicts will integral conservation increasing proportions world's are impacted by urbanization.

Abstract Organismal functional strategies form a continuum from slow- to fast-growing organisms, in response common drivers such as resource availability and disturbance. However, whether there is synchronisation of these at the entire community level unclear. Here, we combine trait data for >2800 above- belowground taxa 14 trophic guilds spanning disturbance gradient German grasslands. The results indicate that most consistently respond through both direct trophically mediated effects, resulting ‘slow-fast’ axis community. Using 15 indicators carbon nutrient fluxes, biomass production decomposition, also show fast communities are associated with faster rates ecosystem functioning. These findings demonstrate ‘slow’ ‘fast’ can be manifested whole communities, opening new avenues ecosystem-level classification.

The effectiveness of poultry vaccination in preventing the transmission highly pathogenic avian influenza viruses (AIVs) has been debated, and its impact on wild birds remains uncertain. Here, we reconstruct movements H5 subtype AIV lineages among vaccinated poultry, unvaccinated birds, worldwide, from 1996 to 2023. We find that there is a time lag viral different host populations were more frequent than those poultry. Furthermore, our findings suggest HA (hemagglutinin) gene lineage circulated predominately Chinese experienced greater nonsynonymous divergence adaptive fixation other lineages. Our results indicate epidemiological, ecological, evolutionary consequences widespread may be linked complex ways much work needed better understand how such interventions affect to, within, birds.

On average, shifted their ranges by 2.4 km/year. These shifts, were significantly different from expectations due cover.
