Abstract The distribution of amphibians is conditioned by historical factors and ecological drivers. Thus, Ecological Niche Models are important tools to provide information on the potential distribution of the species and determine where they will be requirements in future. Mainly, rare species or with restricted areas of occurrence, because this information are essential to understanding of their living area, microhabitat use, or natural history, serving as a basis for preservation actions. Xenohyla eugenioi is a poorly known species, restricted to transition areas of Caatinga and Atlantic Forest from Minas Gerais to Sergipe. This species exhibits little biological information available and few specimens housed in museums, which difficulty to plan conservation strategies. Here our aim was modeling the current and future distribution and discussing about conservation of Xenohyla eugenioi. We searched for occurrence records through literature and scientific collections data. For the future (2071-2100), we used ensemble models from three algorithms (CTA, GLM and ANN) to two shared socioeconomic pathways (SSP370 and SSP585 scenarios). This species has approximately 650 km in straight line between the extreme localities, occurring mainly in bromeliads near to water bodies. The Ensemble method indicates the most suitable areas of occurrence were over ecotonal range between Caatinga and Atlantic Forest and our projections have showed suitable conditions to highlands (up to 1.000 m). However, in the future, is expected total erosion of the X. eugenioi populations, due climatic changes, which reinforce the caution to conservation of this poorly known species and necessity of studies about its ecology, natural history and distribution. Moreover, we hope that this work can contribute to the discovery of new records, characterizing the narrower niche space than this species may actually inhabit. drivers Thus Mainly area use actions Sergipe museums strategies data 20712100, 20712100 2071 2100 , (2071-2100) CTA, CTA (CTA ANN SSP370 SSP (SSP37 SSP58 scenarios. scenarios . scenarios) 65 localities bodies up 1000 1 000 1.00 m. m m) However X populations changes ecology Moreover inhabit 2071210 207 210 (2071-2100 SSP37 (SSP3 SSP5 6 100 00 1.0 207121 20 21 (2071-210 SSP3 (SSP 10 0 1. 20712 2 (2071-21 (2071-2 (2071- (2071 (207 (20 (2 (

Abstract Faunal inventories contribute to our understanding of regional diversity, and are fundamental for policy and decision-making regarding the management and conservation of large natural areas. This study aimed to inventory and compile information on amphibian species occurring in the North Pantanal region, in the municipal limits of Cáceres, Mato Grosso, Brazil. We used three methods to inventory amphibian species: (1) fieldwork, (2) analysis of specimens deposited in scientific collections, and (3) literature reviews. We registered 49 amphibian species in Cáceres. Of them, 48 species belonged to the Anura order and were distributed across eight families and 20 genera, and one species belonged to the Gymnophiona order (Siphonops paulensis). The families Leptodactylidae (20 spp.) and Hylidae (17 spp.) were dominant in terms of richness, accounting for 75.5% of all species found in Cáceres. The remaining families had between four and one species each. The municipality is strongly influenced by non-forested formations (e.g., the Cerrado and Pantanal) and presents a high species richness for a non-forested location in Brazil. Our findings highlight Cáceres as one of the richest areas in amphibian species in the North Pantanal region, expanding our knowledge regarding frog diversity. This study provides a foundation for future conservation strategies and additional assessments of amphibian species in light of potential population declines and other emerging threats. diversity decisionmaking decision making region Grosso Brazil 1 (1 fieldwork 2 (2 collections 3 (3 reviews 4 them genera Siphonops paulensis. paulensis . paulensis) spp. spp 17 755 75 5 75.5 each nonforested non forested e.g., eg e g (e.g. threats ( 7 75. e.g. (e.g e.g

Resumo: O domínio ecológico da Mata Atlântica possui uma notável diversidade de anuros com grande grau de endemismo, a maioria distribuídos em áreas de alta altitude, representadas principalmente pelas montanhas ao longo da Serra da Mantiqueira e Serra do Mar. Apesar de sua importância biológica, a região ainda mostra uma lacuna de amostragem em relação aos anfíbios. Assim, apresentamos o primeiro levantamento sistemático da anurofauna da Área de Proteção Ambiental Boqueirão da Mira (APABM), na região da Zona da Mata, Minas Gerais, Brasil. Foram realizadas duas expedições de campo, onde quinze pontos amostrais foram inventariados por meio de procura ativa noturna e diurna audiovisual em locais de reprodução e forrageio. A anurofauna da APABM apresentou 43 espécies distribuídas em 12 famílias, sendo a família Hylidae a mais rica (17 espécies). Além disso, quatro espécies tiveram sua distribuição ampliada devido aos nossos achados (Hylodes perere, Physalaemus rupestris, Bokermannohyla ibitipoca e Ololygon cosenzai), todas elas sendo endêmicas do Complexo da Mantiqueira. Este estudo revelou que a APABM possui uma grande diversidade de espécies de anuros, mais representativas do que regiões adjacentes como o Parque Estadual do Ibitipoca e próximas à riqueza apresentada pelo Parque Estadual da Serra Negra da Mantiqueira. Este trabalho demonstra a grande importância da APABM para a conservação, destacando-a como uma área de alta diversidade de espécies de anuros regionais.

Abstract: The ecological domain of the Atlantic Forest holds a remarkable diversity of anurans with a great degree of endemism, most of which are distributed in high altitude areas, mostly represented by the mountains along the Mantiqueira Complex and Serra do Mar. Despite its biological importance, the region still shows a gap of sampling concerning the amphibians. Thus, we present the first systematic survey of the anuran fauna from Área de Proteção Ambiental Boqueirão da Mira (APABM), in the region of Zona da Mata, Minas Gerais state, Brazil. Two fieldwork expeditions were performed where fifteen sample points were inventoried through active night search and day audiovisual survey in breeding and foraging sites. The anuran fauna of the APABM presented 43 species distributed in 12 families, with the Hylidae family being the richest (17 species). Besides, four species had their distribution increased due to our findings (Hylodes perere, Physalaemus rupestris, Bokermannohyla ibitipoca and Ololygon cosenzai), all of them as endemic to the Mantiqueira Complex. This study revealed that the APABM has a great diversity of anuran species, more representative than adjacent regions such as the Parque Estadual Ibitipoca and close to the richness presented for the Parque Estadual Serra Negra da Mantiqueira. This work demonstrates the great importance of the APABM for conservation, highlighting it as an area of high diversity of the regional anuran species.
