Competent Non‐Native Alternative Host Reduces Infection Success in a Generalist Parasite

Ecology and Evolution, Volume 16, Issue 6, June 2026.
In this study, we experimentally assessed how the addition of a non‐native alternative host affects the infection success of the larval generalist trematode, Diplostomum pseudospathaceum, in fish intermediate hosts. Our results demonstrate that the presence of alternative hosts, especially the non‐native ones, can reduce parasite transmission through ...

Environmental DNA Reveals Major Shifts in Fish and Amphibian Diversity and Distribution in Alpine Lentic Ecosystems of Southwest China, Supporting Improved Conservation and Management

Diversity and Distributions, Volume 32, Issue 6, June 2026.
ABSTRACT Aim Alpine lentic ecosystems are naturally fish‐poor or fish‐free, yet they have received numerous non‐native fish introductions globally. Studies have demonstrated that alien fish have negative impacts on aquatic organisms, particularly amphibians, which are highly susceptible to habitat alterations.

Alterações histopatológicas em girinos de rã-touro alimentados com rações comerciais de diferentes níveis protéicos Histopathological alterations in bullfrog tadpoles fed commercial diets with three levels of crude protein

Revista Brasileira de Zootecnia, 2008
Realizaram-se necropsia e exame histopatológico de girinos de rã-touro (Rana catesbeiana) alimentados com rações comerciais formuladas com 32, 36, 45 ou 55% de proteína bruta (PB) visando estabelecer a relação entre o nível de proteína bruta da ração e a

Prevalence and Mechanisms of Sustained Force Production in the Musculature of the Southern Alligator Lizard (Elgaria multicarinata)

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 345, Issue 3, Page 272-281, April 2026.
ABSTRACT The southern alligator lizard (Elgaria multicarinata) exhibits prolonged mate‐holding behavior. This behavior maybe be underpinned by a phenomenon known as sustained force, observed in the jaw muscles of this species, in which the muscle fails to relax between subsequent contractions.

Characterization of NLRP3 isoforms in bullfrog Aquarana catesbeiana and their role in antibacterial immunity

Journal of the World Aquaculture Society, Volume 57, Issue 2, April 2026.
Abstract The NLRP3 inflammasome is essential for innate immunity against pathogens, yet its function in amphibians remains poorly understood. Here, we identified and cloned two novel isoforms of NLRP3 from the American bullfrog (Aquarana catesbeiana), designated AcNLRP3 X1 and AcNLRP3 X2, with open reading frames of 2397 bp (798 aa) and 2874 bp (957 aa)

Host Genus and Habitat Use Shape the Distribution of Batrachochytrium dendrobatidis Lineages in a Hyper‐Diverse Tropical Amphibian Community

Ecology and Evolution, Volume 16, Issue 3, March 2026.
Anthropogenic change has facilitated the spread of the amphibian chytrid fungus Batrachochytrium dendrobatidis (Bd) in Brazil's Atlantic Forest, where two Bd lineages (Bd‐GPL and Bd‐Brazil) co‐occur. We successfully genotyped 252 Bd‐positive samples from a diverse amphibian assemblage spanning aquatic and terrestrial habitats and found that Bd lineage ...
