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

Restoration Ecology, EarlyView.
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

Biological 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

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

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

Journal 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.

Gene expression differs in susceptible and resistant amphibians exposed to Batrachochytrium dendrobatidis. [PDF]

, 2018
Chytridiomycosis, the disease caused by the fungal pathogen Batrachochytrium dendrobatidis (Bd), has devastated global amphibian biodiversity. Nevertheless, some hosts avoid disease after Bd exposure even as others experience near-complete extirpation ...

Size‐Dependent Habitat Selection in a Tropical Freshwater Crayfish: Preference for Vegetated Refugia

Ecology and Evolution, Volume 16, Issue 5, May 2026.
Young freshwater crayfish need shelter to survive, but it is often unclear whether they actively choose safe habitats or simply remain where they are found. We show that craylings and juvenile red claw crayfish prefer vegetated habitats over bare sand or gravel, and that this preference becomes stronger as crayfish grow.

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

Brazilian 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.

Differential Susceptibility May Not Drive Chytridiomycosis Related Declines in Multi‐Host Amphibian Communities

Ecology and Evolution, Volume 16, Issue 3, March 2026.
We investigated how Batrachochytrium dendrobatidis (Bd) affects multi‐host amphibian communities in Tasmania, Australia. Despite differential susceptibility, we found no evidence of population declines in susceptible species, suggesting that current environmental conditions may buffer communities against Bd impacts.

Non-native Amphibian Pet Trade via Internet in Poland [PDF]

, 2018
Overharvesting and trade in amphibian populations is one of the causes of their global decline. Online trade not only encourages the exploitation of an increasing number of rare and endangered amphibian species from all over the world but also ...
