“…The complementary use of species range maps with occurrence data is a promising route for advancing efforts to local-scale conservation decisions, supporting our species distribution data (Maréchaux et al 2017). Such approaches for improving decision-making effectiveness are even more urgent in species-rich regions, where conservation strategies should ensure the lack of biodiversity data (Maréchaux et al 2017;Lourenço-de-Moraes et al 2019). In this context, we suggest that the forest fragments located in the coastal parts of the southern Bahia region and the Espírito Santo state deserve special attention in conservation plans because they hold the highest proportion of ecological connectivity along the Central Corridor of the Brazilian Atlantic Forest.…”

“…Areas with high turnover rates can be associated to areas with low species richness under the current climate (Duan et al 2016), which in the case of the Atlantic Forest may be represented by higher altitude areas. Moreover, low turnover rates in high altitude areas can strengthen mountainous regions as potential climatic refuges (Carnaval et al 2009;Randin et al 2009;Araújo et al 2011;Lourenço-de-Moraes et al 2019).…”

“…Species with access to mountainous regions may migrate to higher altitude areas with lower temperatures (Colwell et al 2008), which in the case of the Atlantic Forest, should retain greater humidity due to better-preserved forest cover (Ribeiro et al 2009). However, the survival of threatened amphibians in fragmented tropical landscapes is dependent on the integrity and persistence of their PAs (Urbina-Cardona 2008;Ochoa-Ochoa et al 2009;Lourenço-de-Moraes et al 2019).…”

“…In an attempt to understand these effects, modelling species responses to different climatic scenarios of environmental conditions has proven to be an effective tool (Carnaval and Moritz 2008;Diniz-Filho et al 2009;Austin and Van Niel 2011;Araújo and Peterson 2012). Researchers are combining environmental spatial data with ecological and evolutionary processes to predict how species will shift their ranges in the future (Elith et al 2010;Kearney et al 2010;Martensen et al 2017;Triviño et al 2018;Lourenço-de-Moraes et al 2019). Ecological niche models (ENMs), also referred to as species distribution models (SDMs) (Peterson et al 2011;Rangel and Loyola 2012), have been increasingly used to estimate the spatial ranges of species for future scenarios of climate change (Peterson et al 2011).…”

Ecological connectivity depends on key elements within the landscape, which can support ecological fluxes, species richness and long-term viability of a biological community. Landscape planning requires clear aims and quantitative approaches to identify which key elements can reinforce the spatial coherence of protected areas design. We aim to explore the probability of the ecological connectivity of forest remnants and amphibian species distributions for current and future climate scenarios across the Central Corridor of the Brazilian Atlantic Forest. Integrating amphibian conservation, climate change and ecological corridors, we design a landscape ranking based on graph and circuit theories. To identify the sensitivity of connected areas to climate-dependent changes, we use the Model for Interdisciplinary Research on Climate by means of simulations for 2080-2100, representing a moderated emission scenario within an optimistic context. Our findings indicate that more than 70% of forest connectivity loss by climate change may drastically reduce amphibian dispersal in this region. We show that high amphibian turnover rates tend to be greater in the northeastern edges of the corridor across ensembles of forecasts. Our spatial analysis reveals a general pattern of low-conductance areas in landscape surface, yet with some well-3 connected patches suggesting potential ecological corridors. Atlantic Forest reserves are expected to be less effective in a near future. For improved conservation outcomes, we recommend some landscape paths with low resistance values across space and time. We highlight the importance of maintaining forest remnants in the southern Bahia region by drafting a blueprint for functional biodiversity corridors.

“…The state of Espírito Santo, southeastern Brazil harbors 136 (22%) species listed for Atlantic Forest. The state’s most sampled area is the municipality of Santa Teresa, which comprises high functional and phylogenetic diversity of amphibians (Almeida et al 2011, Campos et al 2017, Lourenço-de-Moraes et al 2019). There are conflicting reports regarding the species composition and richness in this area.…”

A checklist of the amphibians of Santa Teresa municipality, in southeastern Brazil is presented based on fieldwork, examination of specimens in collections, and a literature review. This new amphibian list of Santa Teresa includes 108 species, of which 106 (~98%) belong to Anura and two (~2%) to Gymnophiona. Hylidae was the most represented family with 47 species (43%). Compared to the previous amphibian lists for Santa Teresa, 14 species were added, 17 previously reported species were removed, and 13 species were re-identified based on recent taxonomic rearrangements. Of the 14 species added, 11 (79%) were first recorded during our fieldwork and specimen examination. It is also the first list of caecilians for Santa Teresa. This list suggests that Santa Teresa has 0.16 species per km2 (i.e., 108 species/683 km2), one of the highest densities of amphibian species in the world at a regional scale. This richness represents 78% of the 136 anurans from Espírito Santo state and 10% of the 1,080 amphibians from Brazil. We highlight the need for long-term monitoring to understand population trends and develop effective conservation plans to safeguard this remarkable amphibian richness.

Amphibians are undergoing global-scale declines due to the increased incidence of anthropogenic stressors. The loss of species with unique evolutionary histories and functional traits poses a serious risk to the maintenance of ecosystem functions in aquatic environments, already directly affected by several anthropogenic land-use changes. Here, we investigated the influence of anthropogenic stressors (roads and Pinus monocultures) on functional, phylogenetic and taxonomic composition and functional dispersion of an anuran metacommunity of 33 ponds in southern Brazil. We expected for the relative influence of anthropogenic stressors to vary according to the compositional facet, with a greater influence of these stressors on the functional and phylogenetic than on the taxonomic facet. We also expected traits related to habitat exploration (head shape and eye size and position) to be more influenced by Pinus monocultures, while the traits related to the dispersion and the physiological control of individuals (limb length and body mass) to be similarly influenced by roads and Pinus.To evaluate this, we used PERMANOVA analyses for each of the compositional facets and anthropogenic stressor, and path models to verify all possible relationships between patterns of functional dispersion and anthropogenic stressors. We found that, while the distance from ponds to Pinus monocultures influences the phylogenetic composition, distance to roads influences the functional composition; distance to roads affects mostly the functional dispersion of the communities. These anthropogenic stressors affect the structure of anuran communities, even those formed by generalist species in terms of habitat use. There is a decline in diversity in communities located close to Pinus and roads, leading to losses in the evolutionary history accumulated in these communities.The control of vehicle traffic during reproduction periods and the maintenance of areas .
