Escalas en ecología: su importancia para el estudio de la selección de hábitat en aves

El Hornero, 2006
En este trabajo discuto sobre qué entendemos por escala en ecología y cómo las dimensiones espaciales de nuestro estudio pueden influir en los patrones que observamos y en nuestras conclusiones sobre los procesos que los producen. Analizo la importancia

The collective application of shorebird tracking data to conservation

Conservation Biology, EarlyView.
Abstract Addressing urgent conservation issues, such as the drastic declines of North American migratory birds, requires creative, evidence‐based, efficient, and collaborative approaches. The abundance of over 50% of monitored North American shorebird populations has declined by over 50% since 1980. To address these declines, we developed a partnership

Subspecies taxonomy reflects social and geographic patterns of taxonomic effort in tetrapods

Conservation Biology, EarlyView.
Abstract Subspecies have been used in conservation biology to account for intraspecific patterns in genetic diversity, which is crucial to long‐term population viability. Although over 3200 subspecies are currently assessed by the International Union for Conservation of Nature Red List, their biological relevance remains controversial.

Ecology and morphology as drivers of passerine song differentiation across an island archipelago

Ibis, EarlyView.
We conducted an integrative analysis to explore possible explanations for the song differentiation in bird populations from the mainland and the Tres Marías Archipelago (TMA) on the central‐western Pacific coast of Mexico. We first analysed the effect of isolation on cultural transmission by comparing repertoire size and genetic fixation in four ...

Phylogenomics of the American robin (Turdus migratorius) reveals hidden lineages and introgression

Journal of Systematics and Evolution, EarlyView.
Phylogenomic analyses of Turdus migratorius uncover four previously unrecognized lineages, including a divergent Baja California lineage (T. m. confinis). The results reveal complex evolutionary relationships that depart from simple models of continuous divergence, supported by evidence of introgression between the Mexican lineage and its previously ...

Plant–hummingbird interactions, floral abundance, and floral traits for three altitudinal gradients in the Americas

Ecology, Volume 107, Issue 11, November 2026.
Abstract Plant–animal interactions result in many ecosystem services, such as pollination. In the western hemisphere, and especially the Neotropics, hummingbirds are important pollinators for thousands of plant species, yet there is much to be learned about the spatial and temporal variation in mechanisms influencing these interactions. We collected an
