Repeated trends in altitudinal gradients of diversity: How habitat filtering and biotic interactions structure ecological communities

Journal of Animal Ecology, Volume 95, Issue 9, Page 1672-1685, September 2026.
This study reveals that tropical butterfly communities show remarkably consistent elevational patterns of diversity and phylogenetic structure across regions with contrasting evolutionary histories, demonstrating how regional species pools and local ecological factors jointly shape biodiversity along altitudinal gradients.

Biogeographic Disconnect and Biotic Homogenization in the Heart of the Amazon: Dominance of Exotic Species in Urban Trees

Biotropica, Volume 58, Issue 5, September 2026.
Exotic taxa dominate the urban woody flora, with potentially invasive species posing a direct risk to adjacent primary forest remnants. Historical management has favored a simplified, cosmopolitan species pool over regional biodiversity. There is failure to implement local native‐priority mandates, offering concrete ecological targets for urban ...
