Oviposition and father presence reduce clutch cannibalism by female poison frogs
Frontiers in Zoology, 2019 Background The consumption of conspecific young by adult individuals is a common phenomenon across various animal taxa. Possible adaptive benefits of such behaviour include the acquisition of nutrients, decreased competition for one’s own offspring, and ...

Quantifying exposure of amphibian species to heat waves, cold spells, and droughts
Conservation Biology, Volume 39, Issue 5, October 2025.Abstract Globally, amphibians face severe threats, such as climate change and associated extreme events. Our goal was to quantify global amphibian exposure to 3 classes of extreme events: heat waves, cold spells, and droughts. We used the MERRA‐2 extreme climate events data and the standardized precipitation–evapotranspiration index database to ...

Molecular Ecology, Volume 34, Issue 15, August 2025.Abstract Colour signals play pivotal roles in different communication systems, and the evolution of these characters has been associated with behavioural ecology, integumentary production processes and perceptual mechanisms of the species involved. Here, we present the first insight into the molecular and histological basis of skin colour polymorphism ...

Brazilian Journal of BiologyThe understanding of feeding habits is important for anurans in general, both from an ecological and a phylogenetic perspective. For diurnal poison frogs belonging to the Dendrobatidae family, diet aspects play a crucial role in their defense and ...

The Constructive Neutral Evolution of Behaviour
Ecology and Evolution, Volume 15, Issue 7, July 2025.We explain how constructive neutral evolution (CNE) can lead to the evolution of nonfunctional behavioural complexity, highlighting a mechanism that is unknown to behavioural ecologists despite being frequently considered by molecular biologists. We summarise indirect evidence that suggests behavioural CNE has occurred and outline how the hypothesis ...
