A new record for American Bullfrog (Lithobates catesbeianus) in San Juan, Argentina Nuevo registro de rana toro americana (Lithobates catesbeianus) en San Juan, Argentina

open access: yesRevista Mexicana de Biodiversidad, 2011
We report a new record of Lithobates catesbeianus (American bullfrog) from Argentina. L. catesbeianus was first introduced to San Juan Province 11 years ago in Calingasta Department, where the habitat is pre-cordilleran.

American bullfrog (Lithobates catesbeianus) invasion in California

open access: yes, 2020
Invasive species have far-reaching ecological and economic impacts. The American bullfrog (Lithobates catesbeianus) has spread globally through anthropogenic activity and has been named one of the world's worst invasive species. Bullfrogs have especially impacted native amphibians in California through predation, competition, and disease. Bullfrogs are

Dimensions of dace dynamics: temporal variation in abundance and survival of an imperiled desert fish guide habitat restoration

open access: yesRestoration Ecology, Volume 34, Issue 5, July 2026.
Abstract Introduction Desert fishes are vulnerable to anthropogenic environmental alterations that degrade habitat and reduce water availability, but these same fishes benefit from restoration actions that reverse the causes of decline. Ash Meadows speckled dace (Rhinichthys osculus nevadensis) is a federally endangered minnow endemic to the Mojave ...

The impacts of biological invasions

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1255-1310, June 2026.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

Effect of Sciatic Nerve Transection on acetylcholinesterase activity in spinal cord and skeletal muscles of the bullfrog Lithobates catesbeianus

open access: yesBrazilian Journal of Biology, 2017
Sciatic nerve transection (SNT), a model for studying neuropathic pain, mimics the clinical symptoms of “phantom limb”, a pain condition that arises in humans after amputation or transverse spinal lesions.

Oases of endemism: Regional aquifer desert springs serve as biodiversity hotspots preserving vulnerable endemic taxa in the Great Basin and Mojave Desert regions

open access: yesLimnology and Oceanography, Volume 71, Issue 6, June 2026.
Abstract Spring ecosystems in arid regions often serve as crucial biodiversity hotspots by providing some of the only reliable sources of surface water. However, anthropogenic activities and climate change have severely degraded spring ecosystems worldwide, emphasizing the need for large‐scale multidisciplinary studies informing conservation efforts ...

Implementing real‐time acoustic monitoring for conservation: A case study using edge computing and satellite transmission

open access: yesConservation Science and Practice, Volume 8, Issue 6, June 2026.
We evaluated a prototype acoustic monitoring device that performs onboard species classification and transmits detection summaries via satellite, enabling near real‐time data access from remote field sites. Deployed alongside conventional autonomous recording units at eight Northern Spotted Owl territories, the system demonstrated successful ...

Urbanisation Restructures but Does Not Reduce Freshwater Pond Biodiversity

open access: yesDiversity and Distributions, Volume 32, Issue 6, June 2026.
ABSTRACT Aim Urbanisation is a dominant driver of landscape change leading to widespread displacement, degradation and fragmentation of habitat for native species and numerous studies have documented loss of biodiversity in response. However, most studies focus on a small range of taxa (e.g., vertebrates, plants), leaving many other groups poorly ...

Transcriptomic analysis reveals the hepatic response mechanisms of the Chinese spiny frog (Quasipaa spinosa) to Citrobacter freundii infection

open access: yesJournal of the World Aquaculture Society, Volume 57, Issue 3, June 2026.
Abstract To elucidate the pathogen and host response mechanisms underlying mass mortality in Quasipaa spinosa, dominant bacteria were isolated from diseased individuals and identified as Citrobacter freundii by morphological, physiological, and biochemical characterization, 16S rRNA sequencing, and phylogenetic analysis.

Profile of cortisol, glycaemia, and blood parameters of American Bullfrog tadpoles Lithobates catesbeianus exposed to density and hypoxia stressors Perfil de cortisol, glicemia, e parâmetros sanguineos de girinos de rã-touro Lithobates catesbeianus expostos a diferentes densidades e hipóxia

open access: yesPesquisa Veterinária Brasileira, 2012
The aim of this study was to evaluate alterations to the physiological profile (cortisol, glycaemia, and blood parameters) of Lithobates catesbeianus caused by the stressors density and hypoxia.
