An investigation of toe‐tapping behaviour in anurans by analysis of online video resources
Journal of Zoology, Volume 312, Issue 3, Page 158-162, November 2020., 2020 A database of online videos featuring feeding toads and frogs, particularly Dendrobatidae, was constructed in order to investigate factors affecting toe tapping, a behaviour which has been noted to accompany feeding across various taxa. The collected data revealed 19 species which have previously not been reported to exhibit the behaviour and a ...

Evolutionary integration of the frog cranium
Evolution, Volume 74, Issue 6, Page 1200-1215, June 2020., 2020 Abstract Evolutionary integration (covariation) of traits has long fascinated biologists because of its potential to elucidate factors that have shaped morphological evolution. Studies of tetrapod crania have identified patterns of evolutionary integration that reflect functional or developmental interactions among traits, but no studies to date have ...

New Piperidine alkaloids from fire ants are not sequestered by the green and black poison frog ( Dendrobates auratus ) [PDF]
, 2021 Neotropical poison frogs possess alkaloid-based antipredator defenses which they sequester from a diet of arthropods such as oribatid mites and myrmicine ants.

Ecology and Evolution, Volume 9, Issue 8, Page 4917-4930, April 2019., 2019 We conducted a survey testing for the fungal pathogen Batrachochytrium dendrobatidis (Bd) in four lowland sites in Costa Rica to identify local host‐pathogen dynamics and to describe the abiotic environment for this pathogen. We found evidence that lowland study sites exhibit enzootic dynamics with low infection intensity and moderate to high ...

Adult poison dart frogs avoid potential heterospecific competitors using their sense of smell
Ethology, Volume 130, Issue 8, August 2024.Little is known about the use of chemical senses in frogs. Using a two‐choice testing arena, we tested the reaction of adult poison dart frogs to different odours. We show first evidence of the avoidance of heterospecific odours and conclude that olfaction in these frogs plays a more prominent role than previously believed.

Tap dancing frogs: Posterior toe tapping and feeding in Dendrobates tinctorius
Ethology, Volume 130, Issue 7, July 2024.Various species of amphibians are known to tap their toes, but the precise function of this behavior remains mysterious. We demonstrated that Dendrobates tinctorius poison frogs tap more while feeding, especially in the presence of a conspecific. Tap rate was also higher when prey was accessible and when on pliable surfaces. We suggest tapping may stir
