Ethology, Volume 132, Issue 3, Page 204-215, March 2026.This study examined how background colour influences behaviour and development in golden mantella (Mantella aurantiaca) tadpoles across ontogeny. Tadpoles preferred darker backgrounds, and this preference got less strong with increasing age. Individuals reared in darker conditions were less active but did not differ in growth rate and shelter use when ...

Characterization of a bacteriocin produced by enterococcus gallinarum CRL 1826 Isolated from captive bullfrog: evaluation of its mode of action against Listeria monocytogenes and gram-negatives [PDF]
, 2015 Enterococcus gallinarum CRL 1826 isolated from an American bullfrog (Lithobates catesbeianus) skin inhibits the growth of Citrobacter freundii, Pseudomonas aeruginosa (bullfrog pathogens) and Listeria monocytogenes by a synergistic effect between organic

American bullfrog management on Vancouver Island
, 2013 The American bullfrog (Lithobates catesbeianus) is an invasive amphibian native to the eastern region of North America that is now located throughout the south west coast of British Columbia due to ill-fated frog’s legs operations. Brought to Vancouver Island in the 1930’s, the American bullfrog has spread throughout the south island and threatens to ...

Methods in Ecology and Evolution, Volume 17, Issue 2, Page 322-338, February 2026.Abstract The biodiversity crisis necessitates spatially extensive methods to monitor multiple taxonomic groups for evidence of change in response to evolving environmental conditions. Programs that combine passive acoustic monitoring and machine learning are increasingly used to meet this need. These methods require large, annotated datasets, which are

Evolution of research on global amphibian declines
Conservation Biology, Volume 40, Issue 1, February 2026.Abstract In the late 1980s, the scientific community became aware of severe, enigmatic amphibian population declines. These declines triggered a wave of research focused on quantifying their extent and identifying key drivers. We used text‐analysis techniques, including topic modeling and geoparsing, to examine the evolution of research focused on ...

American bullfrog invasion in Argentina: where should we take urgent measures?
Biodiversity and Conservation, 2011 Argentina is the country with the most geographically extended biological invasion of the American bullfrog (Lithobates catesbeianus) in South America after Brazil. Here, we used a maximum entropy ecological niche modeling algorithm (using records of the native range of American bullfrog) to project the model onto the whole of Argentina.

Global Trends in Drought Impacts on Wildlife—A Review
Global Change Biology, Volume 32, Issue 2, February 2026.We reviewed peer reviewed literature pertaining to instances of anomalous drought (any drought event that deviates from standard conditions (e.g., dry season) when compared to a long term average) and its impacts on wildlife. We summarize the directional effects of drought on wildlife, as well as how drought is quantified across the literature ...

Detection and succession properties of forested vernal pools with eDNA metabarcoding
Ecological Solutions and Evidence, Volume 7, Issue 1, January–March 2026.We examined the capacity of environmental DNA metabarcoding for studying biodiversity of forested vernal pools, using multiple assays to investigate different eukaryotic communities over space and time. Our results suggest that metabarcoding can serve as a complementary tool for ‘scaling up’ vernal pool biodiversity monitoring, illuminating ecological ...
