Integrating refugia modeling and decision science to support climate‐adaptive conservation in the Sierra Nevada

open access: yesConservation Science and Practice, Volume 8, Issue 1, January 2026.
Abstract To reduce detrimental impacts of anthropogenic change, natural resource managers often look for place‐based solutions to minimize biodiversity loss. Climate‐change refugia, areas buffered from contemporary climate change, can enable the persistence of valued natural resources and prolong the benefits of conservation action.

Tracking viral particles in the intestinal contents of the American bullfrog, Lithobates catesbeianus, by Transmission Electron Microscopy

open access: yesArquivo Brasileiro de Medicina Veterinária e Zootecnia, 2014
Feces are an important viral agent elimination route for infected carrier animals and in aquatic organisms these pathogenic agents can very rapidly propagate due to the habitation environment. The objective of this work is to track viral particles in the

Stress Nutrition in Aquatic Animals: From Definition to Practice

open access: yesReviews in Aquaculture, Volume 18, Issue 1, January 2026.
ABSTRACT Aquaculture faces numerous challenges, with stress being one of the major issues that lead to growth loss, metabolic disorders, weakened immunity, redox imbalance, and organ damage in aquatic animals. Nutritional intervention is one of the effective strategies to address these problems. Traditional research has primarily focused on the impacts

Effects of Predator Species and Size on Prey Escape Success Through the Digestive Tract

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
Adults of the aquatic beetle Regimbartia attenuata can survive passage through the digestive tracts of six predator (frog) species, including a non‐native bullfrog. Their active movement through the gut likely facilitates their escape through the cloaca, irrespective of predator species or size.

Changes in morphology over time due to denaturing agents in an ethanol and camphor solution [PDF]

open access: yesNatural History Collections and Museomics
The ethanol collections of the Africamuseum require an approved denaturing agent, that can be used to top-up containers in which, historically, camphor-denatured ethanol has been used.

Carcass yield and proximate composition of bullfrog (Lithobates catesbeianus)

open access: yesActa Scientiarum: Animal Sciences, 2015
This work evaluated five classes of weight of bullfrog (Lithobates catesbeianus) seeking to define the ideal slaughter weight for the species. We used 79 bullfrogs, distributed in a completely randomized design (class 1 < 100 g (n = 10); class 2 from 101 to 150 g (n = 17); class 3 from 151 to 200 g (n = 24); class 4 from 201 to 250 g (n = 14); and ...
