The effect of trait choice on hybrid species distribution model projections under climate change
Ecography, Volume 2026, Issue 6, June 2026.Species distribution models (SDMs) have been increasingly combined with thermal performance data to enhance their transferability and to provide a physiological explanation for the predicted geographic patterns. Yet, while it is widely acknowledged that thermal sensitivities may vary among biological traits, it remains largely unexplored to what extent

Road mortality alters the body size and age structure of amphibians
Oikos, Volume 2026, Issue 6, June 2026.Road mortality affects a wide range of animal species, including amphibians. Worldwide, many amphibian species, including the Asiatic toad Bufo gargarizans, are impacted by road mortality, but the ecological consequences remain poorly understood. This study aimed to evaluate how road mortality influences population traits by comparing body sizes and ...
