A curious case of herbivory in the common toad Rhinella arenarum arenarum during hibernation in captivity conditions
(Asociación Herpetológica Argentina, 2013-09)
Shape variation in lentic and lotic tadpoles of Melanophryniscus (Anura: Bufonidae)
(Taylor & Francis Ltd, 2011-08)
The bufonid genus Melanophryniscus includes 26 species that are divided into three phenetic groups based on adult morphology. Larvae develop in environments such as temporary ponds, streams or phytotelms. We studied variation ...
Molecular phylogeny and morphometric analyses reveal deep divergence between Amazonia and Atlantic Forest species of Dendrophryniscus
(ACADEMIC PRESS INC ELSEVIER SCIENCESAN DIEGO, 2012-03)
Dendrophryniscus is an early diverging clade of bufonids represented by few small-bodied species distributed in Amazonia and the Atlantic Forest. We used mitochondrial (414 bp of 12S, 575 bp of 16S genes) and nuclear DNA ...
Morphological Changes in Skin Glands During Development in Rhinella Arenarum (Anura: Bufonidae)
(Wiley-liss, Div John Wiley & Sons Inc, 2016-01)
Avoiding predation is critical to survival of animals; chemical defenses represent a common strategy among amphibians. In this study, we examined histologically the morphology of skin glands and types of secretions related ...
The use of ephemeral reproductive sites by the explosive breeding toad Melanophryniscus rubriventris (Anura: Bufonidae): is it a predator cue mediated behavior?
(Taylor & Francis, 2015-10)
Amphibians detect quality signals when selecting reproduction sites. We hypothesize that Melanophryniscus rubriventris, an explosive breeding toad that reproduces in small, ephemeral water bodies, is able to select sites ...
Cutaneous Resistance to Evaporative Water Loss in Brazilian Rhinella (Anura: Bufonidae) from Contrasting Environments
(AMER SOC ICHTHYOLOGISTS HERPETOLOGISTS, 2009)
Influenced by taxonomic position. For example, bufonids are regarded as exhibiting a permeable skin that seems typical for terrestrial anurans. However, this assumption is supported by information on only four bufonid ...
Niche overlap and resource partitioning among five sympatric bufonids (Anura, Bufonidae) from northeastern ArgentinaSobreposição de nicho e partilha de recursos entre cinco espécies simpátricas de bufonídeos (Anura, Bufonidae) do nordeste da Argentina
(Melopsittacus Publicações Científicas, 2009-07)
The niche overlap and resource partitioning were analyzed for five sympatric bufonids from Northeastern Argentina: Rhinella schneideri, R. bergi, R. fernandezae, R. granulosa, and Melanophryniscus cupreuscapularis. The ...
Helminth community structure in the Argentinean bufonid melanophryniscus klappenbachi: importance of habitat use and season
(Springer, 2014-07)
The goal of this study was to evaluate the relative influence of terrestrial habits, season, and host body size on the species richness and abundance of helminth parasites in the toad Melanophryniscus klappenbachi, for ...
Morphological and Molecular Variation in the Pumpkin Toadlet, Brachycephalus ephippium (Anura: Brachycephalidae)
(Soc Study Amphibians ReptilesSt LouisEUA, 2011)
Living in fast-water: morphology of the gastromyzophorous tadpole of the bufonid Rhinella quechua (R. veraguensis group).
(Wiley-liss, Div John Wiley & Sons Inc, 2009-06)
We describe the bufonid gastromyzophorous tadpoles of Rhinella quechua from montane forest streams in Bolivia. Specimens were cleared and stained, and the external morphology, buccopharyngeal structures, and the ...
