The impact of urbanization on amphibians has received some attention in the conservation literature. Despite the various impacts on animal life, some species can persist along the cities structures by adjusting their natural histories. Leptodactylusfuscus is a common anuran species occurring in South America, which can commonly be found in urban environments. Herein, we compare the diet of L.fuscus between an urban and a wild environment. We collected 57 individuals of L.fuscus and analysed their diet, which differed significantly between the two sites. In the urban environment, Coleoptera were the prevalent prey items, whereas specimens from the wild site had a more diverse diet.
Biogeographic tools support spatial distribution pattern hypotheses and help to determine priority areas for conservation. Our aim was to verify biogeographic patterns for anurans in three mountain complexes in southeastern Brazil, as well as to discuss the status of species conservation recorded and the biogeographical units evaluated. We selected 16 areas distributed in the Serra da Mantiqueira complex, south of Serra do Espinhaço and Serra da Canastra. We used the occurrence (geographic coordinates) of each species in the localities to determine areas of endemism applying the Endemicity Analysis method. We also tested whether similarity between areas was explained by geographic distance (Multiple Regression on distance Matrices-MRM). The Serra do Itatiaia, Serra da Canastra, Plateau of Poços de Caldas and Serra do Cipó were the areas that presented the highest number of species restricted to them. Through the Endemicity Analysis, we identified four areas of endemism with higher scores. The MRM revealed that the geographic distance explained 41% of species dissimilarity between areas. Most of the endemic species from these areas have inaccurate conservation statuses (data deficient or unevaluated). These results highlight the need for greater research efforts towards understanding species restricted by distribution, as well as the priority in conserving these endemic areas.
We present a list of the anuran amphibians from municipality of Barão de Monte Alto, state of Minas Gerais, southeastern Brazil. This region is part of the remaining Atlantic Forest and the studied environments are represented by forest patches and open habitats. We recorded 29 anuran species, many of these typical and/or endemic to the Atlantic Forest. None of the species registered was considered under threat of extinction in state, national or international red-lists. It is worth noting, however, the presence of the tree frogs Dendropsophus pseudomeridianus, the first record of this species in the state of Minas Gerais, and D. bipunctatus, marking its expanded distribution in various locations of Minas Gerais. The present list examines zoogeography and conservation of anurans in the Brazilian southeast and broadens the knowledge of the anuran fauna in this region.
Acidentes ofídicos são considerados um problema de saúde pública. O Brasil é 3º país com mais casos de acidentes. O Ministério da Saúde do Brasil criou o Sistema de Informações de Agravos e Notificações (SINAN), possibilitando o acompanhamento dos casos para cada estado. Minas Gerais apresenta altos índices de acidentes ofídicos, o que pode estar relacionado a proporção de trabalhadores rurais e à considerável contribuição agropecuária ao PIB estadual. Assim, nosso objetivo foi avaliar o perfil epidemiológico dos acidentes ofídicos no estado de Minas Gerais para servir como base para estratégias eficientes de diminuição de acidentes e no socorro às vítimas. Obtivemos dados de acidentes do SINAN ocorridos entre 2007 e 2019. Encontramos diferenças significativas entre os números de casos por ano, com aumento gradual dos registros, como também maiores registros de ocorrência nos meses chuvosos (janeiro a abril). As vítimas acometidas são, principalmente, homens, de 20 a 60 anos, perfil da maioria dos trabalhadores rurais. A alta porcentagem de cura das vítimas pode estar relacionada à agilidade do atendimento, como, também, ao fato da maior proporção de casos leves e moderados no estado. O gênero Bothrops apresentou maiores índices de acidentes seguido por Crotalus, Micrurus e Lachesis, respectivamente. As regiões com maiores índices de acidentes ofídicos estão associadas à maior população rural e à agropecuária, sendo o Triângulo Mineiro/Alto Paranaíba e Norte de Minas com as maiores taxas de acidentes per capita e Zona da Mata e Oeste de Minas com menores taxas.
There are many gaps in our biodiversity knowledge, especially in highly diverse regions such as the Neotropics. Basic information on species occurrence and traits are scattered throughout different literature sources, which makes it difficult to access data and ultimately delays advances in ecology, evolution, and conservation biology. We provide species occurrence and trait data for amphibian species in the Upper Paraguay River Basin, central South America. The compiled information is made available through two different datasets that hold (i) 17K species occurrence records and (ii) 30 species-level traits for 113 amphibian species. The first dataset includes the species occurrence records and informs specimen id, collection of housing, locality, geographical coordinates, geographic accuracy, collection date, and collector name. The second dataset covers species-level attributes on morphometry, diet, activity, habitat, and breeding strategy. These datasets improve accessibility to spatial and trait data for amphibian species in the Pantanal ecoregion, one of the largest wetlands on Earth.
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.
In this study, we evaluated the reproductive activity and the temporal and spatial distributions of anuran assemblages in three environments within a semideciduous forest in Southeast Brazil, located at Municipality of Barão de Monte Alto, State of Minas Gerais, Brazil. The fi eld activities were carried out during three consecutive days, monthly throughout the rainy seasons of 2013-2014 and 2014-2015. We recorded 28 anurans species, distributed in eight families. We observed the spatial-temporal distribution of some species, and their associated reproductive behaviors through exploration of vocalizations at different sites. The spatial and temporal distribution of the species seems to adapt to abiotic and biotic factors of their environment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
