Effects of Harmful Algal Blooms on Amphibians and Reptiles are Under‐Reported and Under‐Represented
Environmental Toxicology and Chemistry, Volume 43, Issue 9, Page 1936-1949, September 2024.Abstract Harmful algal blooms (HABs) are a persistent and increasing problem globally, yet we still have limited knowledge about how they affect wildlife. Although semi‐aquatic and aquatic amphibians and reptiles have experienced large declines and occupy environments where HABs are increasingly problematic, their vulnerability to HABs remains unclear.

Effect of different types of sesquiterpene lactones on the maturation of Rhinella arenarum oocytes
Zygote, 2014 SummaryThe sesquiterpene lactones (STLs) are a large class of plant secondary metabolites that are generally found in the Asteraceae family and that have high diversity with respect to chemical structure as well as biological activity. STLs have been classified into different groups, such as guaianolides, germacranolides, and melampolides etc., based ...

Herpetological Journal, 2020 Chemical cues associated with predation attempts allow prey to trigger defensive behaviours. Accordingly, tadpoles of several species of anurans display strong behavioural responses to chemical cues of injured conspecifics. As part of the antipredator response, tadpoles show rapid and sustained inhibition of activity when exposed to chemical cues of ...

Austral Ecology, Volume 49, Issue 1, January 2024.We performed a systematic review on the available literature on in situ studies of neotropical tadpole diets focusing on diet composition and its sources of variation. Such studies approached in just a few instances the effects of seasonality, developmental stage and food selectivity on diet composition, but the available data indicate none of these ...

Polyaniline nanofibers: Acute toxicity and teratogenic effect on Rhinella arenarum embryos
Chemosphere, 2012 The fate and effect of nanomaterials in the environment is of paramount importance towards the technological application of the materials. This work shows the ecotoxicological potential of polyaniline (PANI) nanofibers in the larvae Rhinella arenarum by means of AMPHITOX test.

Duration of extinction trials as a determinant of instrumental extinction in terrestrial toads (Rhinella arenarum) [PDF]
Animal Cognition, 2017 Instrumental learning guides behavior toward resources. When such resources are no longer available, approach to previously reinforced locations is reduced, a process called extinction. The present experiments are concerned with factors affecting the extinction of acquired behaviors in toads.

Austral Ecology, Volume 49, Issue 1, January 2024.Resumo Os girinos são componentes importantes de muitas teias alimentares aquáticas, pois influenciam as populações em outros níveis tróficos e, consequentemente, a transferência de energia entre os ecossistemas aquáticos e terrestres. O que os girinos consomem é um fator chave para suas funções ecológicas. As assembleias de anuros neotropicais incluem

Journal of Experimental Zoology Part A: Ecological Genetics and Physiology, 2012 AbstractSeveral studies indicate that wild free‐living vertebrates seasonally regulate plasma glucocorticoids. However, not only glucocorticoids but also the amount of receptors is important in determining biological responses. In this context, seasonal regulation of glucocorticoid receptor (GR) is crucial to modulate the response to glucocorticoids ...
