Anuran males and females adopt different reproductive and behavioral strategies in different contexts. We investigated the reproductive ecology and territorial behavior of the treefrog Boana goiana (B. Lutz, 1968) from the Brazilian Cerrado. We hypothesized that competitor density/proximity would increase the behavioral responses of B. goiana males...

Neighbour-stranger discrimination is an important mechanism in social behaviour, as it allows the individual to avoid the high energetic costs of repeated agonistic interactions with neighbours. In some anuran species, the owners of territories respond more aggressively towards strangers than neighbours. Here, we investigated whether gladiator frog...

We report, for the first time, a case of nocturnal foraging behavior under artificial light by the Giant Ameiva (Ameiva ameiva) – a known diurnal teiid lizard. We also update the list of diurnal lizard species known to respond to artificial light provided by Perry et al. (2008).

Male anurans emit different call types in specific social contexts. Such calls represent a communication pathway for species recognition, mate choice, and male-male competition mediation. The acoustic parameters of these calls can be under directional and/or stabilizing selection due to female choice, which influences intra-and inter-individual cal...

A release call is a type of vocalisation emitted by anurans mainly to avoid either intra- or interspecific mating, during the breeding season. Due to the importance of these calls in the social context of anuran behaviour, we hypothesised that the release call parameters of Rhinella species should be associated with body size. We found a negative r...

Aim: Species distributions are one of the most important ways to understand how communities interact through macroecological relationships. The functional abilities of a species, such as its plasticity in various environments, can determine its distribution, species richness and beta diversity patterns. In this study, we evaluate how functional tra...

Amphibians are constantly exposed to pollutants and the stress of agricultural activities. We selected three anuran amphibian species Dendropsophus minutus, Boana albopunctata, and Physalaemus cuvieri, totaling 309 individuals. We collected tadpoles in 15 permanent ponds: 5 soybean crops, 3 corn crops, and 7 nonagricultural lands. Our study provide...

Our study evaluated 163 individuals, being 74 soybean farmers, occupationally exposed to pesticides, and 89 individuals from Goias municipalities, Central Brazil, with similar conditions to the exposed group, comprising the control group. Of the 74 soybean farmers, 43 exposed directly to pesticides and 31 exposed indirectly. The exposed group consi...

The anuran skin characteristically has different types of glands, most of which are microscopic and are spread throughout the skin. Some species have specialized regions where glands agglomerate, forming macroglands. The description of the external morphology of Ololygoncentralis (Pombal & Bastos, 1996) revealed the presence of an inguinal gland. O...

Reptiles are highly susceptible to climate change, responding negatively to thermal and rainfall alterations mainly in relation to their reproductive processes. Based on that, we evaluated the effects of climate change on climatically suitable areas for the occurrence of snakes in the Atlantic Forest hotspot, considering the responses of distinct r...

Climate refuges have been used by several species over historical climate change. Ectothermic species often display good models for climate change studies because they are highly sensitive to temperature. Analysis of species loss with ecosystem and evolutionary values helps to understand environmental processes and climate change consequences. We d...

Acoustic signals are used in diverse social contexts by frogs and serve as relevant tools for studies on evolution, description and identification of species. Here, we described the advertisement, aggressive and release calls of Rhinella sebbeni, a poorly known toad from the Rhinella margaritifera species group. The description of the vocal reperto...

The herbicide glyphosate is widely used on Brazilian crops and commonly found in water bodies. Despite its usefulness in controlling pests and increasing agricultural production, improper use of this environmental contaminant might accelerate the decline of species, especially frogs. The aim of this study was to evaluate the genotoxic and mutagenic...

Cytogenetic data can be useful for taxonomic and phylogenetic studies, as well as to provide information about chromosome evolution. Therefore, it may help design conservation priorities for some threatened species, such as anurans. Herein, we describe the karyotypes of Scinax constrictus and Ololygon centralis, native endemic species from the Braz...

Nestedness among species assemblages implies that sites of lower species richness are subsets of richer sites in a regional species pool. This nestedness is a reflection of a non-random process of species loss as a consequence of factors that promote the disaggregation of assemblages. The impoverishment of assemblage diversity is more often observe...

The number of species of frogs in the South American genus Adelophryne has increased in recent years, and it has become apparent that this group contains a substantial amount of undescribed diversity. Currently the genus contains nine described species and five candidate species. Here we describe the tenth species of the genus Adelophryne from the...

Beginning in November 2018, Brazilian legislation regulating access to genetic heritage and associated traditional knowledge will cause a bureaucratic collapse of Biodiversity research in Brazil. Law number 13.123/2015 and Decree 8772/2016 impose severe barriers to basic and applied research, and to international cooperation by introducing mandator...

Advertisement calls are often used as essential basic information in studies of animal behaviour, ecology, evolution, conservation, taxonomy or biodiversity inventories. Yet the description of this type of acoustic signals is far to be completed, especially in tropical regions, and is frequently non-standardized or limited in information, restricti...

Amphibians inhabiting agricultural areas are constantly exposed to large amounts of chemicals, which reach the aquatic environment during the rainy season through runoff, drainage, and leaching. We performed a comet assay on the erythrocytes of tadpoles found in the surroundings of agricultural fields (soybean and corn crops), where there is an int...

We described the release and distress calls of Rhinella abei (Baldissera, Caramaschi & Haddad, 2004) (Rhinella crucifer group) and Rhinella icterica (SPix, 1824) (Rhinella marina group).

In anurans, vocalization is the primary communication form and acoustic parameters are influenced by climatic conditions, but also by social contexts. We investigated calling site use and within-individual variation of acoustic parameters throughout the night in the gladiator-frog Hypsiboas goianus. We expected that large males would call closer to...

The potential mutagenic and genotoxic effects of the herbicide atrazine were investigated in different developmental stages of Dendropsophus minutus tadpoles. These animals were exposed to 4 nominal concentrations of atrazine (2.25, 4.5, 9, and 18 mg/L) and 40 mg/L of Cyclophosphamide as a positive control, for 96 h. Negative controls were also add...

Acoustic signals are the main communication mechanisms in anuran amphibians. Herein is described the vocal repertoire, call variation, and calling site of Boana jaguariaivensis from a population of the Tibagi, Paraná State, southern Brazil. Seventeen males were recorded in December 2012 and February 2013. Males of B. jaguariaivensis used shrubs, he...

Acoustic signals are employed to support the correct designation of species and enables the discrimination between individuals. We analyzed both intra and interindividual variability of the advertisement call of Physalaemus centralis on the basis of specimens recorded in eight localities of the Cerrado in central Brazil. Within-individual variation...

In face of the accelerated degradation of streams located within the Brazilian Cerrado, the knowledge of distribution patterns is very important to aid conservation strategies. The aim of this work is to increase the knowledge of the stream's fish fauna in the State of Goiás, Brazil. 12 streams from the municipalities of Barro Alto and Niquelândia...
