Automated detection of frog calls and choruses by pulse repetition rate. [PDF]

open access: yesConserv Biol, 2021
Abstract Anurans (frogs and toads) are among the most globally threatened taxonomic groups. Successful conservation of anurans will rely on improved data on the status and changes in local populations, particularly for rare and threatened species.

Egg burying behaviour in Pristimantis highlights the link between direct development and specialised parental care. [PDF]

open access: yesEcol Evol, 2023
We report the first case of egg‐burying behaviour in a neotropical direct‐developing frog. Both parents remained near the nest during the following day. This rare observation sheds light over the intricate reproductive behaviours of terrestrial amphibians and suggests that the evolution of direct development has selected for highly specialized forms of

Reproductive colonization of land by frogs: Embryos and larvae excrete urea to avoid ammonia toxicity. [PDF]

open access: yesEcol Evol, 2022
Frogs have evolved terrestrial eggs many times, offering an excellent opportunity to assess traits that may facilitate aquatic‐to‐terrestrial transitions. Our results suggest the importance of physiological adaptations and physiological plasticity during early life stages, specifically the early onset of urea excretion, its upregulation under dry ...
