Don't You Know That I'm Toxic? Wild Birds Learn to Avoid a Novel Aposematic Warning Signal
The foraging behaviours of predators towards aposematic prey have been studied extensively and there is much empirical evidence to support this theory. Often, studies involving wild species are relatively short‐term and so there is a possibility that any aversive behaviours exhibited by predators are merely neophobic. In this study, we ensure predators

This study examines the global distribution of marine reptiles and mammals, revealing contrasting biogeographic patterns shaped by their distinct evolutionary histories. Marine mammals exhibit non‐random distributions with elevated taxonomic distinctness in the Arctic and North Pacific, whereas marine reptiles show phylogenetic clustering in tropical ...

Snake head shape is weakly constrained by phylogeny but strongly influenced by ecology. Significant convergence was detected in fossorial and aquatic snakes, while diet mainly drove morphological variation without convergence. ABSTRACT Morphological convergence—where distantly related species evolve similar traits in response to shared ecological ...

New reports on parasitism by Haplometroides buccicola (Digenea, Plagiorchiidae) in Brazilian snakes
The occurrence of Haplometroides buccicola (Digenea, Plagiorchiidae) in the esophagus of two Brazilian snakes is reported in the present study. The trematodes were collected from one Micrurus corallinus (Elapidae) and one Phalotris lativittatus ...

Grandmothers and deadly snakes: an unusual project in “citizen science”
We describe initial results of an innovative citizen science project that is unusual in its taxonomic focus (deadly sea snakes), its location (the Indo‐Pacific), and its primary contributors (grandmothers from the city of Noumea, New Caledonia).
