Data from: Dark pigmentation limits thermal niche position in birds

Ismael Galván, Sol Rodríguez-Martínez & Luis M. Carrascal
1. Animal pigmentation has evolved because of several adaptive functions. In the case of pigmentation produced by melanins, the most common pigments in animals, the main function is protection against UV radiation. However, pigmentation also affects animal surface's ability to absorb solar radiation and gain heat, which may represent a thermal constraint for endotherms due to their relatively high and constant body temperatures. 2. As darker colours absorb more radiation than lighter colours, dark-pigmented endotherm...

Data from: Too hard to swallow: a secret secondary defence of an aposematic insect

Lu-Yi Wang, Wen-San Huang, Hsin-Chieh Tang, Lung-Chun Huang & Chung-Ping Lin
Anti-predator strategies are significant components of adaptation in prey species. Aposematic prey are expected to possess effective defences that have evolved simultaneously with their warning colours. This study tested the hypothesis of the defensive function and ecological significance of the hard body in aposematic Pachyrhynchus weevils pioneered by Alfred Russel Wallace nearly 150 years ago. We used predation trials with Japalura tree lizards to assess the survivorship of ‘hard’ (mature) vs. ‘soft’ (teneral) and ‘clawed’...
