Anura, one of the most studied taxa regarding intersexual selection, has been considered a model for experiments on female preferences for decades. Despite this, there is still much to learn about most species and different topics. We describe the current state of knowledge on anuran intersexual selection (e.g., most studied taxa, themes, types of...

Despite acoustic signals playing a fundamental role on animal behavior and reproduction, our understanding of the mechanisms driving their evolution is still scarce. Due to the high cost of signaling, several adaptive bioacoustics hypotheses have been proposed to explain call design. While Acoustic Adaptation Hypothesis (AAH) postulates the habitat...

Extinction risk assessments are valuable conservation tools, especially for sensitive groups like amphibians, which are facing escalating threats from habitat loss and degradation. In this scenario, Brazil stands out as a pivotal player in amphibian conservation due to its exceptional amphibian diversity. Between 2010 and 2014, 973 amphibian specie...

Phoresy is likely a commensal interaction, in which a phoront attaches itself to the body of a host for dispersal. Host traits and environmental characteristics may determine phoresy patterns. We examined whether the density of microscopic phoronts on frogs living in the water between the leaves of bromeliads (phytotelma) was determined by the spec...

The Brazilian Cerrado is undergoing important changes. It is estimated that 70% of its natural area has converted to human use. The loss and fragmentation of natural habitats is considered the main cause of species loss in ecosystems. However, the lack of knowledge of biodiversity makes it difficult to design effective conservation measures. This a...

Ambotuy Favoring males’ specific sexual signals, female preferences play a major role in frogs’ evolutionary process by selecting traits linked to those signals. However, the factors constraining and determining those preferences are scarcely explored in an evolutionary background. Here, through a phylogenetic comparative approach we check whether...

The data on the reptilian fauna of the state of Goiás are one-off and reveal a lack of information about this group. The aim of the research was to know the composition of the reptile fauna within the area of the Anglo American mining company, evaluating the relationship of the species with the years, the types of environments and the presence of i...

Global change is predicted to induce shifts in anuran acoustic behavior, which can be studied through passive acoustic monitoring (PAM). Understanding changes in calling behavior requires automatic identification of anuran species, which is challenging due to the particular characteristics of neotropical soundscapes. In this paper, we introduce a l...

Changes in the natural landscape and the indiscriminate use of pesticides can have a major impact on aquatic environments and have contributed to the worldwide decline of amphibian populations. In the present study, we sampled tadpoles of three anuran amphibians (Boana albopunctata, Physalaemus cuvieri, and Dendropsophus minutus) from ponds in six...

Global change is predicted to induce shifts in anuran acoustic behavior, which can be studied through passive acoustic monitoring (PAM). Understanding changes in calling behavior requires the identification of anuran species, which is challenging due to the particular characteristics of neotropical soundscapes. In this paper, we introduce a large-s...

During the breeding season, hundreds of anurans agglomerate at spawning sites, where a diversity of social contexts arise. In this scenario, anurans may alter their vocal repertoire according to the immediate social context, to overcome intraspecific competition. To evaluate the acoustic response of Boana goiana to successive interactions with a co...

Despite the great diversity of Brazilian anuran species, there are still many knowledge gaps about the acoustic communication of these animals. Among the species, those classified as ‘Data Deficient’ have the greatest gaps in knowledge on their behavior. This is the case of Boana ericae, a species belonging to the Boana pulchella group, endemic to...

The development of new acoustic technologies has promoted remarkable advances in biodiversity monitoring. Passive acoustics is increasingly being used in ecological research to remotely assess animal communities. This recent revolution opens new questions about the precision and efficiency of these emerging methods in tracking biodiversity. However...

Quantitative analysis of the acoustic communication system in anurans is a relevant step toward understanding how acoustic traits variation is related to conspecific recognition and discrimination. Here, we report on the advertisement call variation of male Scinax fuscomarginatus at three levels: within-individual, between-individual, among-populat...

Herbicides improve the productivity of a monoculture by eliminating weeds, although they may also be toxic and have negative effects on non-target organisms, such as amphibians. The present study evaluated the genotoxic, mutagenic, and histopathological hepatic responses of Dendropsophus minutus tadpoles to acute exposure (96 h) to the herbicide gl...

Introdução: Atualmente, conhecemos 209 espécies de anuros para o Cerrado. Devido às características fisiológicas e baixa capacidade de dispersão, este grupo possui um importante papel como bioindicadores. Ao longo dos anos o Cerrado vem sofrendo impactos negativos por ações antrópicas, como a agricultura e a pecuária. Diante dos avanços da degradaç...

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...

Brazil’s network of public Protected Areas (PAs) occupy 28.9% of its territory, and large remnants of native vegetation are also found on private lands, therefore landowners play central roles in any conservation debate: they are required to protect native vegetation on their lands and are neighbours of PAs. In this study, we tested the hypothesis...

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...

The increasing destruction of natural environments worldwide favored more and more alien species' dispersal, distancing people from nature and consequently from native species. We investigated undergrad students' perception about alien and native Brazilian species evaluating classes of the first (freshmen) and last semesters (seniors) of four cours...

Research on environmental perception is essential for the understanding of individuals’ relations and expectations towards natural environments. Here, we evaluated the perception of high school students on exotic and native species in Brazil. We interviewed 371 students from two high schools located in the state of Goiás, one with and one without a...

Bioacoustics is an effective way of recording detailed data during population surveys and monitoring. In the present study, we used an automated digital recorder (ADR) to describe the temporal variation in the calling activity of Scinax fuscomarginatus (Lutz, 1925) in central Brazil. We also evaluated the role of climatic variables (air temperature...

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).

This study aims to identify species richness and composition patterns of the ichthyofauna in different landscape matrices (forest, pasture and eucalypt crops) and to evaluate the variation of species composition in different matrices, identifying possible indicator species. We selected 21 streams; 7 were surrounded by native vegetation, 9 surrounde...

Given the increasing use of sympatric species to investigate niche differentiation and resource partition in biological communities, our study analyzes diet composition differences and trophic niche overlap between the sympatric species Physalaemus cuvieri and P. atim in the municipalities of Silvnia and Leopoldo Bulhes, Brazil. We used stomach flu...

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...

Understanding landowners’ intention to voluntarily engage in conservation initiatives is essential to designing more realistic projects and interventions. In this study, we used the Theory of Planned Behavior to identify the psychological constructs underlying landowners’ intention to restore areas with native vegetation on their properties over th...

Overcoming the Linnaean and Wallacean shortfalls is an urgent task for biologists. It has been estimated that only a small fraction of the biodiversity on Earth is known, while geographic ranges of already described species are poorly documented. We performed a systematic review and modeling on species descriptions of Brazilian amphibians to evalua...

Guia dos anfíbios do estado de Goiás e do Distrito Federal, Brasil. Field Guide for Amphibians from the state of Goiás and the Federal District, Central Brazil

Anurans living in species-rich assemblages may experience acoustic niche overlap. To deal with potential masking interference during reproductive activity, species can present acoustic partitioning based on differences in calling period. Studies addressing this question in tropical assemblages have mainly focused on the seasonal scale, and little i...

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...

This study aims to identify species richness and composition patterns of the ichthyofauna in different landscape matrices (forest, pasture and eucalypt crops) and to evaluate the variation of species composition in different matrices, identifying possible indicator species. We selected 21 streams; 7 were surrounded by native vegetation, 9 surrounde...

Landowners' decisions reshape landscapes, affecting the distribution and maintenance of ecosystem services (ESs). In Brazil, 53% of all remaining native vegetation is on private farms, reinforcing the importance of these stakeholders. The aim of this study was to identify landowners’ perceptions of the native areas on their properties as sources of...

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 use of biodiversity surrogates is often suggested to increase the cost-effectiveness of biomonitoring programs, as this demands less time and taxonomic expertise. In addition, the detection of multi-taxon associations is a first step toward a better understanding of how organisms interact with each other. Such a multi-taxon association is terme...

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...
