Oviposition and father presence reduce clutch cannibalism by female poison frogs

open access: yesFrontiers 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 ...

The Constructive Neutral Evolution of Behaviour

open access: yesEcology 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 ...

Diet of Ameerega braccata (Steindachner, 1864) (Anura: Dendrobatidae) from Chapada dos Guimarães and Cuiabá, Mato Grosso State, Brazil

open access: yesBrazilian Journal of Biology
The 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 ...

Hide and Seek: Species Detectability in a Biodiversity Hotspot Increased by Environmental DNA

open access: yesEnvironmental DNA, Volume 7, Issue 4, July–August 2025.
We demonstrated through Bayesian modeling that eDNA metabarcoding offers equivalent or higher detectability than traditional field inventory techniques for anuran species in a biodiversity hotspot. The number of recorded species was also higher in seven out of ten sampled streams.

Generation length of the world's amphibians and reptiles

open access: yesEcography, Volume 2025, Issue 7, July 2025.
Variation in life histories influences demographic processes, from adaptive changes to population declines leading to extinction. Among life history traits, generation length offers a critical feature to forecast species' demographic trajectories such as population declines (widely used by the IUCN Red List) and adaptability to environmental change ...

Potential effects of climate change on the threatened Malagasy poison frogs: A multispecies approach

open access: yesEcosphere, Volume 16, Issue 6, June 2025.
Abstract Climate change is exposing ecosystems to novel conditions, and understanding its potential effects on species distributions is crucial. Those effects can significantly affect species with narrow environmental requirements inhabiting closed systems where dispersal is limited.
