Critical tipping points in dung beetle communities: Implications for conservation in the Atlantic Forest biome

open access: yesInsect Conservation and Diversity, EarlyView.
Minor land‐use changes consistently lead to abrupt biodiversity shifts across all diversity dimensions, favoring generalist dung beetle species while excluding sensitive specialists. These shifts are observed at lower environmental change rates than previously considered, with significant changes apparent after just 25% habitat loss.

Coyote Range Expansion in the Human‐Modified Tropics of Mesoamerica

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
Coyotes have expanded their range into southeastern Mexico, Guatemala, and Belize, increasingly occupying human‐modified landscapes. This expansion is ongoing, with rising detection rates over time and records in both disturbed and forested environments, highlighting a paradox where anthropogenic change enables native carnivore expansion.

Predation on Northern Silky Anteater (Cyclopes dorsalis) by Tiger Rat Snake (Spilotes pullatus) in a Rainforest Fragment in Costa Rica

open access: yesBiotropica, Volume 58, Issue 2, March 2026.
We report the first predation event of a northern silky anteater by a tiger rat snake. This predation underscores how little is known about the nocturnal anteater and its predators. As the snake is commensal with humans, anthropogenic habitat alterations might have exposed the anteater to a novel predation pressure.
