Occurrence of a Cavity‐Nesting Tropical Swallow Is Associated to Riverbed Lithology

Austral Ecology, Volume 51, Issue 6, June 2026.
ABSTRACT Understanding the factors shaping species distribution is a key challenge in ecology and biogeography. While dispersal limitations, environmental features, and biotic interactions are commonly recognized as key determinants of species abundance and distribution, some species exhibit patchy distributions that remain hard to explain.

Projected Impacts of Climate Change on Interactions Between Plants and Avian Frugivores Across the Americas

Global Ecology and Biogeography, Volume 35, Issue 6, June 2026.
ABSTRACT Aim Frugivorous birds provide crucial seed‐dispersal functions in terrestrial ecosystems. However, the impact of climate change on plant–avian frugivore interactions remains unclear due to past methodological limitations. In this study, we address this by mapping these interactions across the Americas and projecting shifts in interaction ...
