Profile of cortisol, glycaemia, and blood parameters of American Bullfrog tadpoles Lithobates catesbeianus exposed to density and hypoxia stressors

Pesquisa 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.

Life history linked to immune investment in developing amphibians [PDF]

, 2013
The broad diversity of amphibian developmental strategies has been shaped, in part, by pathogen pressure, yet trade-offs between the rate of larval development and immune investment remain poorly understood. The expression of antimicrobial peptides (AMPs)

Differential Uptake of Gold Nanoparticles by 2 Species of Tadpole, the Wood Frog (Lithobates Sylvaticus) and the Bullfrog (Lithobates Catesbeianus)

, 2017
Engineered nanoparticles are aquatic contaminants of emerging concern that exert ecotoxicological effects on a wide variety of organisms. We exposed cetyltrimethylammonium bromide–capped spherical gold nanoparticles to wood frog and bullfrog tadpoles ...

Do Lithobates catesbeianus tadpoles acclimatise to sub-lethal copper?

International Journal of Environment and Health, 2010
The aim of this work was to study the acute effects of short-term exposure (96 hours) to sub-lethal concentrations of copper (2 and 3 mg L−1) on ecotoxicological stress biomarkers in the aquatic stages of Lithobates catesbeianus (syn. Rana catesbeiana) larvae. To this end, the effects of copper on brain acetylcholinesterase, liver and gill catalase and

Toxicity of Four Common Environmental Chemicals Across Caenorhabditis elegans Life Stages Supporting the One Health Concept

Environmental Toxicology, EarlyView.
ABSTRACT Pesticides and pharmaceuticals are among the most common chemical groups in waterbodies and soils, and their universal distribution raises concerns about potential adverse effects on nontarget organisms and humans. Reproductive output disruption is of particular concern, as it transposes effects from the individual to the next generations at ...

‘Using anuran community diversity and Pseudacris crucifer to predict landscape quality across a land use gradient'

Wildlife Biology, EarlyView.
As human‐modified landscape and climate changes proliferate, maintaining biodiversity and understanding the function and quality of available habitat is imperative. As anurans (frogs/toads) such as Pseudacris crucifer, can be an indicator species of habitat quality and ecosystem productivity, studying the anuran community in a mixed‐land use region ...

Histopathological alterations in bullfrog juveniles fed commercial rations of different crude protein levels Alterações histopatológicas em imagos de rã-touro alimentados com diferentes rações comerciais

Revista Brasileira de Zootecnia, 2009
The relationship between the quality of dietary crude protein and health of bullfrog juveniles (Lithobates catesbeianus) was evaluated by necropsy and histopathological examination of animals.
