Carrion ecology: concepts, interdisciplinary synthesis, and perspectives
Biological Reviews, EarlyView.ABSTRACT Carrion is a ubiquitous resource in both terrestrial and aquatic ecosystems, yet it has long been overlooked in ecological research. Over the past two decades, studies on carrion and the many organisms that exploit it have flourished, revealing not only wide‐ranging ecological functions but also significance far beyond ecology.

Eye Darkening Under Dehydration Stress in the Neotropical Frog Boana punctata (Schneider, 1799)
Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.Dehydration induces a strong and partially reversible increase in iris pigmentation in the Neotropical frog Boana punctata. The tight relationship between iris darkening and hydration state identifies ocular pigmentation as a simple, non‐invasive physiological biomarker with broad potential for assessing hydric stress in amphibian populations ...

Journal of Animal Ecology, EarlyView.We show that ant‐mediated seed dispersal components respond differently to local soil conditions and landscape structure in Caatinga agricultural mosaics. Low‐intensity rainfed croplands maintained or enhanced seed removal compared to natural remnants, highlighting how small‐scale agriculture can sustain key ecological processes in human‐modified dry ...
