Make like a glass frog: In support of increased transparency in herpetology

open access: yesHerpetological Journal, 2021
Across many scientific disciplines, direct replication efforts and meta-analyses have fuelled concerns on the replicability of findings. Ecology and evolution are similarly affected. Investigations into the causes of this lack of replicability have implicated a suite of research practices linked to incentives in the current publishing system.

A polymorphism in oocyte pigmentation in natural populations of the glass frog Espadarana prosoblepon (Centrolenidae)

open access: yesThe International Journal of Developmental Biology, 2021
The adaptive role of amphibian oocyte melanic pigmentation and its molecular control are still elusive. Here we present evidence of a polymorphism in egg pigmentation in the emerald glass frog Espadarana prosoblepon. In Ecuadorian natural populations of this species, females can lay dark brown or pale eggs that develop into normal pigmented tadpoles ...

Frog foams and natural protein surfactants [PDF]

open access: yes, 2017
Foams and surfactants are relatively rare in biology because of their potential to harm cell membranes and other delicate tissues. However, in recent work we have identified and characterized a number of natural surfactant proteins found in the foam ...

The Individual and Combined Effects of Warming and Atrazine on Lithobates pipiens Phenotypes: Implications for Frog Declines. [PDF]

open access: yesJ Exp Zool A Ecol Integr Physiol
ABSTRACT Amphibians are the most threatened vertebrate class globally. Climate change, agrochemicals, and/or pathogens and parasites are implicated in contributing to amphibian declines, either singly or in combination. We investigated individual and combined effects of elevated temperatures and atrazine (2.0 μg/L) on Lithobates [formerly Rana] pipiens
