Genomic Correlates of Disease Recovery in Natural Populations of the Sierra Nevada Yellow-Legged Frog (Rana sierrae). [PDF]

Mol Ecol
ABSTRACT In our rapidly changing world, evolution is likely to play an important role in facilitating the resilience of wildlife populations. The Sierra Nevada yellow‐legged frog (Rana sierrae) provides a rare example of recovery following severe declines caused by the amphibian chytrid fungus (Batrachochytrium dendrobatidis).

Evaluating the Use of Environmental DNA as a Method to Determine Occupancy and Distribution of Coeur d'Alene Salamanders in Montana. [PDF]

Ecol Evol
The purpose of this project was to evaluate the efficacy of eDNA sampling to determine occupancy of Coeur d'Alene salamanders, an “imperiled” species in Montana. Previous methods used to identify occupied sites were haphazard with no measure of detection probability. Due to the unique habitat used by these salamanders (seeps and waterfall spray zones),

Mutagenic effect of a commercial fungicide on Rana catesbeiana and Leptodactylus latrans tadpoles

Anais da Academia Brasileira de Ciências, 2022
We have examined the mutagenic effects of the fungicide Elatus® on tadpoles of Rana catesbeiana and Leptodactylus latrans. Sixty-four tadpoles of each species have been exposed to three concentrations of Elatus® (10, 20, and 50 µg/L-1) during 96 hours ...

Oxidative phosphorylation efficiency, proton conductance and reactive oxygen species production of liver mitochondria correlates with body mass in frogs [PDF]

, 2015
ody size is a central biological parameter affecting most biological processes (especially energetics) and mitochondria is a key organelle controlling metabolism and is also the cell's main source of chemical energy.

Acute and chronic effects of perfluoroalkyl substance mixtures on larval American bullfrogs (Rana catesbeiana).

Chemosphere, 2019
Discovery of elevated concentrations of perfluoroalkyl substances (PFAS) in ground and surface waters globally has heightened concern over their potential adverse health effects. The effects of PFAS are known largely from acute toxicity studies of single
