Using life history to predict outcomes of conservation translocations of herpetofauna

open access: yesAnimal Conservation, Volume 28, Issue 4, Page 592-606, August 2025.
We collected data on key life history traits for all herpetofauna profiled in the IUCN Global Conservation Translocation Perspectives series to examine how life history can predict outcomes and difficulties of conservation translocations. The relationships we found provide important insights for conservation practitioners that can be used in the ...

Successful Transmission and Isolation of a Fungal Pathogen From Wild Frogs to a Captive Amphibian Model Species: Fine Scale Pathogen Genetic Diversity and Infection‐Induced Changes in Skin Bacteria

open access: yesEnvironmental Microbiology, Volume 27, Issue 7, July 2025.
The isolation of Batrachochytrium dendrobatidis (Bd) from low‐load wild amphibians revealed multiple genotypes, including a potential hybrid, highlighting ongoing pathogen genetic mixing in natural environments. Additionally, Bd infection induced skin microbiome shifts in Hymenochirus boettgeri, demonstrating its utility as a model for studying ...

Environmental DNA (eDNA) Quantitative Polymerase Chain Reaction‐Based Assays for Surveying 125 Taxa of Importance to North America

open access: yesEnvironmental DNA, Volume 7, Issue 3, May–June 2025.
We present 125 eDNA quantitative real‐time polymerase chain reaction (qPCR) assays against animal species of importance to North America. We show how these assays were designed and validated to comply with the Canadian national eDNA standards to allow confident eDNA detection for coastal and inland ecological surveys and biosurveillance.

Ultrasound-evoked immediate early gene expression in the brainstem of the Chinese torrent frog, Odorrana tormota [PDF]

open access: yes, 2011
The concave-eared torrent frog, Odorrana tormota, has evolved the extraordinary ability to communicate ultrasonically (i.e., using frequencies>20kHz), and electrophysiological experiments have demonstrated that neurons in the frog’s midbrain (torus ...
