“…Breeding site configuration, such as pond descriptors, for example, would play a bigger role than land use over tadpole species diversity (Dalmolin et al 2020). Although we have no detailed data to support this hypothesis, several studies have shown that microhabitat characteristics affect amphibian richness (D’Anunciação et al 2013; Knauth et al 2018; Figueiredo et al 2019). Forest heterogeneity, leaf litter depth, canopy cover and presence of clearings are examples of local descriptors that are not detected at a landscape level but affect anuran species composition (Ferrante et al 2017; Howell et al 2019).…”

“…At the same time, these habitat changes favor the colonization by species such as Boana faber and Dendropsophus minutus (Aquino et al 2004, 2010; Scott et al 2004; Lavilla et al 2010; Silvano et al 2010). These species are often found in fragmented landscapes and expanding open areas (Preuss 2018; Figueiredo et al 2019; Menin et al 2019). We also recorded the exotic bullfrog ( Lithobates catesbeianus ) in four of the seven remnants.…”

“…In the southern Atlantic Forest, most of the original forest areas were replaced by agriculture, pasture, silviculture and urban areas (Ribeiro et al 2011). Studies on amphibians in this region have associated species diversity with characteristics of habitat heterogeneity (Gonçalves et al 2015; Knauth et al 2018; Figueiredo et al 2019), but few have analyzed wider scales that considered the effects of the landscape on species composition. Landscape analyses allow the detection of changes regarding land use and occupation in scales that are compatible with the species or groups in question (Hamer and Parris 2011), helping define local and regional conservation strategies.…”

We evaluated the influence of landscape configuration on the diversity of anurans in Atlantic Forest remnants in southern Brazil. As natural habits provide better conditions for the survival of amphibians, we expected to find more diverse communities in areas with more forest cover. We sampled tadpoles in 28 breeding sites distributed in seven forest remnants. We recorded 22 anuran species and richness varied from 6 to 12 species between sites. Most of the recorded species were not forest specialists, except for Boana curupi and Crossodactylus schmidti. There was a significant overlap in the species composition between all remnants, and the Generalized Linear Mixed Model indicated that landscape use did not affect species richness. The PERMANOVA showed that forest and livestock farming explained the dissimilarity in the composition of the communities. One possible explanation for this is that the remnants are surrounded by a relatively well-preserved landscape, which offers favorable conditions for the maintenance of local populations and homogenizes species composition across the sampling sites. The lack of any strong association between tadpole species richness and land use suggests that anurans are primally affected by habitat characteristics that are detected only on a fine-scale analysis.

“…In the last decades many studies were developed on anuran amphibian communities from different physiognomies of the Atlantic Rainforest biome (e.g, Heyer et al 1990, Canelas & Bertoluci 2007, Araújo et al 2010, Brassaloti et al 2010, Forlani et al 2010, Vilela et al 2011, Figueiredo et al 2019. Population declines and even local extinctions were detected in some localities, such as Santa Tereza, in Espírito Santo state (Weygoldt 1989), and Serra do Japi (Haddad & Sazima 1992), Estação Biológica de Boracéia (Heyer et al 1988, 1990, Bertoluci & Heyer 1995, Verdade et al 2011 and Estação Biológica do Alto da Serra de Paranapiacaba (Verdade et al 2009), in São Paulo state, which show the importance of ecological studies, even in wellstudied regions, such as southeastern Brazil (Haddad & Prado 2005, Brito 2008, Verdade et al 2012.…”

Anuran fauna of the Parque Estadual Carlos Botelho - Núcleo Sete Barras, southeastern Brazil: species composition, use of breeding sites, and seasonal patterns of breeding activity

et al. 2021

The goal of this work was to study the species composition, the use of breeding sites, and the seasonal patterns of breeding activity of the anuran fauna from Parque Estadual Carlos Botelho - Núcleo Sete Barras, state of São Paulo, southeastern Brazil. Fieldwork was carried out from September 2005 to October 2007 through two main methods: active visual search inside a 10 ha- permanent plot and aural and visual search in seven previously selected aquatic breeding habitats. Species richness was related to the sampling effort by means of species accumulation curve and through non-parametric estimators. Thirty-three species distributed in 12 families were recorded, from which 69% are endemic to the Atlantic Forest. Trachycephalus mesophaeus represents a new record for the park. Cycloramphus lutzorum is included as Data Deficient in the IUCN list. The species accumulation curve did not stabilize, showing some tendency to rise. The use of breeding sites by 20 species was compared using cluster analysis, which revealed two major groups: the first with five species (two habitat generalists and three stream specialists) and the second composed by the other species (with different reproductive modes associated with flooded environments). The breeding period of most species was associated to the rainy season (October to February), and only Scinax hayii showed continuous breeding activity during the entire period of study.

“…On the other hand, habitat characteristics influence the spatial and temporal distributions of species (Campos, Trindade-Filho, Brito, Llorente, & Solé, 2014;Ferreira, Beard, & Crump, 2016;Figueiredo, Storti, Lourenço-de-Moraes, Shibatta, & Anjos, 2019;Hawkins, 2001). Thus, historical dispersal can be understood using environmental data of the localities at which species have been recorded and the geographical boundaries that restrict them (Gaston, 1991).…”

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 traits influence the distribution of amphibians, and hypothesize which functional traits explain the current pattern of amphibian species composition.Location: Atlantic Forest, Brazil. Taxon: Amphibia (Anura and Gymnophiona)Methods: Using potential distributions of Brazilian amphibians from Atlantic Forest based on their functional traits, we analysed the influence of biotic and abiotic factors on species richness, endemism (with permutation multivariate analysis) and beta diversity components (i.e. total, turnover and nestedness dissimilarities).Results: Environmental variables explained 59.5% of species richness, whereas functional traits explained 15.8% of species distribution (geographical species range) for Anuran and 88.8% for Gymnophiona. Body size had the strongest correlation with species distribution. Results showed that species with medium to large body size, and species that are adapted to living in open areas tended to disperse from west to east direction. Current forest changes directly affected beta diversity patterns (i.e. most species adapted to novel environments increase their ranges).Beta diversity partitioning between humid and dry forests showed decreased nestedness and increased turnover by increasing altitude in the south-eastern region of the Atlantic Forest.Main Conclusions: Our study shows that functional traits directly influence the ability of the species to disperse. With the alterations of the natural environment, species more apt to these alterations have dispersed or increased their distribution, which consequently changes community structure. As a result, there are nested species distribution patterns and homogenization of amphibian species composition throughout the Brazilian Atlantic Forest.
