Speciation history shapes patterns of assemblage species richness in birds

This study shows that speciation history influences sympatric species richness in birds, with older clades having higher richness due to longer time for species to accumulate in sympatry.

Trait misalignment risk in North American forests under climate change

The paper quantifies the risk of functional misalignment in North American forests under future climate conditions using trait-based analysis of forest inventory data.

Temperature and Ultraviolet Radiation Drive Divergent Visible and Near-Infrared Reflectance Patterns in Butterflies

This study shows that butterfly visible and near-infrared reflectance respond differently to temperature and UV radiation, with phylogeny influencing trait-environment relationships.

Land-use change undermines the stability of avian functional diversity

Across 1281 bird assemblages and 3696 species, land-use change lowers functional redundancy and resistance to simulated extinctions despite lower vulnerability, hitting frugivores and invertivores hardest.

Projected impacts of climate change on plant-frugivore interactions across the Americas

This study projects declines in plant-frugivore interaction diversity under climate change, with potential mitigation through bird dispersal and dietary flexibility.
