Asymmetric Male Mating Success in Lek-Breeding Rhinella arenarum [PDF]

open access: yesAnimals, 2022
Mate choice is the attempt of an individual to gain higher reproductive fitness by preferring to mate with some individuals and not with others. We studied the role of mate choice in the mating system of the neotropical toad Rhinella arenarum by ...

Demographic and Life-History Responses of Rhinella arenarum to Road-Associated Environments [PDF]

open access: yesAnimals
The global decline of amphibians is linked to habitat loss, with urbanization and roads as major threats. Roads fragment habitats and introduce stressors like pollution, temperature changes, and non-native predators. Despite growing awareness, studies in

First evaluation of novel potential synergistic effects of glyphosate and arsenic mixture on Rhinella arenarum (Anura: Bufonidae) tadpoles [PDF]

open access: yesHeliyon, 2019
The toxicity of glyphosate-based herbicide (GBH) and arsenite (As(III)) as individual toxicants and in mixture (50:50 v/v, GBH-As(III)) was determined in Rhinella arenarum tadpoles during acute (48 h) and chronic assays (22 days). In both types of assays,

Hypothesis-driven dragging of transcriptomic data to analyze proven targeted pathways in Rhinella arenarum larvae exposed to organophosphorus pesticides [PDF]

open access: yesScientific Reports, 2022
Transcriptional analysis of the network of transcription regulators and target pathways in exposed organisms may be a hard task when their genome remains unknown.

The Rhinella arenarum transcriptome: de novo assembly, annotation and gene prediction. [PDF]

open access: yesSci Rep, 2020
AbstractThe common toad Rhinella arenarum is widely distributed in Argentina, where it is utilised as an autochthonous model in ecotoxicological research and environmental toxicology. However, the lack of a reference genome makes molecular assays and gene expression studies difficult to carry out on this non-model species.

Testing the Novel Weapons Hypothesis of the Argentine Ant Venom on Amphibians [PDF]

open access: yesToxins, 2023
The globally invasive Argentine ant (Linepithema humile) possesses a venom lethal to some amphibian species in the invaded range. To test the novel weapons hypothesis (NWH), the effects of the toxin on the cohabiting amphibian species in the ant’s native

Ecotoxicological Characterization of Lithium as a “Timebomb” in Aquatic Systems: Tadpoles of the South American Toad Rhinella arenarum (Hensel, 1867) as Model Organisms [PDF]

open access: yesToxics
The aim of this study was to evaluate the acute lethality and chronic sublethal effects of lithium (Li) on Rhinella arenarum tadpoles as model organisms.

Effect of diet on carboxylesterase activity of tadpoles ( Rhinella arenarum ) exposed to chlorpyrifos

open access: yesEcotoxicology and Environmental Safety, 2017
An outdoor microcosm was performed with tadpoles (Rhinella arenarum) exposed to 125μgL-1 chlorpyrifos and fed two types of food, i.e., lettuce (Lactuca sativa) and a formulated commercial pellet. Acetylcholinesterase (AChE) and carboxylesterase (CbE) activities were measured in liver and intestine after 10 days of pesticide exposure.

Thermal parameters changes in males of Rhinella arenarum (Anura:Bufonidae) related to reproductive periods

open access: yesRevista de Biología Tropical, 2011
The regulation of body temperature in ectotherms has a major impact in their physiological and behavioral processes. Observing changes in thermal parameters related with reproduction allows us to better understand how Rhinella arenarum optimizes a ...

Sublethal effects of atrazine on embryo-larval development of Rhinella arenarum (Anura: Bufonidae)

open access: yesEcotoxicology, 2012
Atrazine (ATR), one of the most widely used herbicides in the world, affects not only target organisms but also the biota in general. Here, the teratogenic and neurotoxic effects of ATR on Rhinella arenarum (South American toad) embryos, and larvae were evaluated by means of standardized bioassays during acute and chronic exposures. The herbicide had a
