This study measures peak load-lifting performance in ruby-throated hummingbirds, finding large individual differences and showing that single-trial protocols best capture repeatability.

The paper assesses mercury biomagnification in an Amazonian river system by analyzing multiple energy pathways across different trophic levels and species.

This paper develops a deep learning framework for Neotropical birdsong classification and analyzes factors affecting classification performance using phylogenetic models.

This study examines elevational variation in hummingbird flight muscle microanatomy across three sites in the Colombian Andes, finding differences in collagen fraction and fiber geometry.

The paper assesses how habitat transformation affects amphibian and reptile diversity and community structure in the Eastern Andes, finding reduced richness and simplified assemblages in disturbed habitats.

This study examines humeral shape evolution in hummingbirds, finding that biomechanical scaling and internal integration are primary drivers, with foraging ecology introducing secondary modifications.

This paper describes a new frog species, Epipedobates currulao, named after a Colombian musical genre, and provides morphological, acoustic, and genetic distinctions from related species.

The paper examines age-related differences in activity patterns of Brown Pelicans, testing competitive exclusion and experience-based adaptation hypotheses, and assesses human fishing impacts on their behavior.
