The Individual and Combined Effects of Warming and Atrazine on Lithobates pipiens Phenotypes: Implications for Frog Declines. [PDF]
J Exp Zool A Ecol Integr PhysiolABSTRACT Amphibians are the most threatened vertebrate class globally. Climate change, agrochemicals, and/or pathogens and parasites are implicated in contributing to amphibian declines, either singly or in combination. We investigated individual and combined effects of elevated temperatures and atrazine (2.0 μg/L) on Lithobates [formerly Rana] pipiens

Tadpole Skin Secretions, Not Food or Temperature, Mediate Costly Cannibal-Induced Plasticity in Invasive Cane Toad Hatchlings. [PDF]
Ecol EvolHatchlings of invasive cane toads respond to the risk of cannibalism by accelerating development but experience significant negative carry‐over effects on fitness in the tadpole stage. Our experiments demonstrate that this hatchling response is induced by chemicals located in the skin of older cannibalistic tadpoles. This response is unique to cannibal

Characterization of StAR protein of Rhinella arenarum (Amphibia, Anura)
General and Comparative Endocrinology, 2020 The steroidogenic acute regulatory (StAR) protein performs the delivery of cholesterol from the outer to inner mitochondrial membrane. This is considered the rate-limiting step of acute steroid production, widely studied in mammals. However, there are only few reports regarding the characterization and expression of StAR protein in non-mammalian ...

Environmental Toxicology and Chemistry, Volume 42, Issue 3, Page 566-580, March 2023., 2023 Abstract Bioavailability has been taken into account in the regulation of nickel in freshwater ecosystems in Europe for over a decade; during that time a significant amount of new information has become available covering both the sensitivity of aquatic organisms to nickel toxicity and bioavailability normalization. The ecotoxicity database for chronic

Frontiers in quantifying wildlife behavioural responses to chemical pollution
Biological Reviews, Volume 97, Issue 4, Page 1346-1364, August 2022., 2022 ABSTRACT Animal behaviour is remarkably sensitive to disruption by chemical pollution, with widespread implications for ecological and evolutionary processes in contaminated wildlife populations. However, conventional approaches applied to study the impacts of chemical pollutants on wildlife behaviour seldom address the complexity of natural ...

Hydroperiod Influences Tadpole Growth and Development in the Endangered Littlejohn's Tree Frog (Litoria littlejohni). [PDF]
Ecol EvolAmphibians globally face significant threats, prompting the need for effective conservation strategies across various life stages. Investigating hydroperiod effects on Litoria littlejohni tadpoles, we exposed them to different water levels over 28 weeks.
