A link between increased temperature and avian body condition in a logged tropical forest

Conservation Biology, Volume 40, Issue 3, June 2026.
Abstract The combined effects of anthropogenic disturbances, such as logging and climate change, remain poorly understood; yet, they are the main threats to tropical biodiversity. Most tropical African countries lack long‐term climate data, so climate impacts on biodiversity cannot be assessed.

Distribution, scale, and drivers of mass mortality events in Europe's freshwater bivalves

Conservation Biology, Volume 40, Issue 2, April 2026.
Abstract Mass mortality events (MMEs) are decimating populations and compromising key ecosystem functions around the globe. One taxon particularly vulnerable to MMEs is freshwater bivalve mollusks. This group has important ecosystem engineering capacities and includes highly threatened and highly invasive taxa.

Canalized to heat, plastic to cold: adaptive coordination of leaf and seed strategies in populations spanning an elevational gradient

New Phytologist, Volume 250, Issue 2, Page 873-884, April 2026.
Summary In tropical mountains, surviving temperature extremes demands finely tuned strategies. We investigated how populations of the bromeliad Pitcairnia flammea across a 2200 m elevational gradient balance genetic canalization and plasticity, and whether thermal strategies are coordinated between seeds and leaves.

Do Energetic Challenges Mimicking Missed Foraging Encourage Torpor Use by a Neotropical Bat?

Biotropica, Volume 58, Issue 2, March 2026.
We experimentally tested whether Merriam's long‐tongued bat (Glossophaga mutica), a Neotropical nectarivorous species, uses heterothermy in response to reduced energy intake. We found that energetically challenged bats maintained subcutaneous temperatures significantly closer to roost temperature during the daytime inactive period.
