Resumo: | Among all the mammal species that occur along every montane altitudinal gradient in southeastern Brazil (i.e. Atlantic Forest), bats are an excellent model for analysis, because they are abundant, and all trophic guilds are represented within the taxon. In mountain chains around the world, bat communities may present two patterns of species richness and diversity: 1) progressive decline in species richness and diversity as the altitude increase or 2) a peak of richness and diversity in intermediate altitudinal level. In this context, we aimed to survey the bat species occurring in the Atlantic Forest remnants located in the Itabapoana drainage basin (IDB) and to verify how altitude affects bat capture rates. We used mist-nets to capture bats, which were set up at ground level, totaling 1,500 m2/ha of sampling effort for each location. The IDB has a diverse assemblage of species (26 species), representing 44% of the bat species of Espírito Santo. Our study showed that there is variation in bat capture rates and species richness, with a turnover of some species along the altitudinal gradient in the IDB. Changes in habitat heterogeneity along the elevation gradient are probably one of the strong ecological factors affecting these assemblage parameters. Furthermore, the data from this study allows the expansion of knowledge of the bat species occurring in the region of the IDB. The diversity of species found, together with the occurrence of rare, threatened, and data deficient species highlights the importance of the region for conservation to understand the species distribution patterns. |

Bat diversity along an altitudinal gradient in the Itabapoana drainage basin, Espírito Santo state, BrazilDiversidade de morcegos ao longo do gradiente altitudinal na bacia do rio Itabapoana, Espírito Santo, BrasilAmong all the mammal species that occur along every montane altitudinal gradient in southeastern Brazil (i.e. Atlantic Forest), bats are an excellent model for analysis, because they are abundant, and all trophic guilds are represented within the taxon. In mountain chains around the world, bat communities may present two patterns of species richness and diversity: 1) progressive decline in species richness and diversity as the altitude increase or 2) a peak of richness and diversity in intermediate altitudinal level.

Entre os mamíferos que ocorrem ao longo de todo gradiente altitudinal em montanhas no sudeste do Brasil (i.e. Mata Atlântica), os morcegos podem ser um excelente modelo de análise, porque são abundantes e apresentam todas as guildas. Nas cadeias de montanhas ao redor do mundo, a comunidade de morcegos pode apresentar dois padrões de riqueza e diversidade de espécies: 1) declínio progressivo na riqueza e diversidade de espécies à medida que a altitude aumenta; ou 2) um pico de riqueza e diversidade no nível altitudinal intermediário. Nesse contexto, o presente estudo teve como objetivo realizar um levantamento das espécies de morcegos ocorrentes nos fragmentos localizados na bacia do rio Itabapoana verificando a influência do gradiente altitudinal nas taxas de capturas dos morcegos. Para a captura dos morcegos, utilizamos redes de neblina, armadas no nível do solo, totalizando um esforço amostral de 1.500 m2/ha para cada localidade. A região do rio Itabapoana apresentou uma elevada riqueza de espécies de morcegos (26 espécies), abrigando 44% das espécies já registradas no Espírito Santo. Nosso estudo mostrou que existe uma variação nas taxas de captura de morcegos e riqueza de espécies, com uma reposição de algumas espécies, ao longo do gradiente altitudinal na região do rio Itabapoana. As mudanças na heterogeneidade do habitat ao longo desse gradiente são provavelmente um dos fatores ecológicos fortes que afetam esses parâmetros. Além disso, os dados desse estudo permitem a expansão do conhecimento das espécies de morcegos que ocorrem na região do Itabapoana. A diversidade de espécies encontrada, juntamente com a ocorrência de espécies raras, destaca a importância da região para a conservação ajudando a entender os padrões de distribuição das espécies.Universidade Federal de Santa Catarina2017-12-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2017v30n4p5910.5007/2175-7925.2017v30n4p59Biotemas; v. 30 n. 4 (2017); 59-712175-79250103-1643reponame:Biotemas (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCenghttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2017v30n4p59/36077Copyright (c) 2017 Rodrigo Cipriano, Sergio Barbiero, Atilla Ferreguetti, Vinicius Lopes, Rodrigo Lemes, Kauê de Paulainfo:eu-repo/semantics/openAccessLopes, Vinicius ChagasLemes, Rodrigo MartinsFerreguetti, Atilla ColomboLage, Sergio BarbieroCipriano, Rodrigo da Silvade Paula, Kauê Freire2019-03-01T17:08:30Zoai:periodicos.ufsc.br:article/51311Revistahttp://www.biotemas.ufsc.br/index.htmPUBhttps://periodicos.ufsc.br/index.php/biotemas/oai||carlospinto@ccb.ufsc.br2175-79250103-1643opendoar:2019-03-01T17:08:30Biotemas (Online) - Universidade Federal de Santa Catarina (UFSC)false |

Among all the mammal species that occur along every montane altitudinal gradient in southeastern Brazil (i.e. Atlantic Forest), bats are an excellent model for analysis, because they are abundant, and all trophic guilds are represented within the taxon. In mountain chains around the world, bat communities may present two patterns of species richness and diversity: 1) progressive decline in species richness and diversity as the altitude increase or 2) a peak of richness and diversity in intermediate altitudinal level. In this context, we aimed to survey the bat species occurring in the Atlantic Forest remnants located in the Itabapoana drainage basin (IDB) and to verify how altitude affects bat capture rates. We used mist-nets to capture bats, which were set up at ground level, totaling 1,500 m2/ha of sampling effort for each location. The IDB has a diverse assemblage of species (26 species), representing 44% of the bat species of Espírito Santo. Our study showed that there is variation in bat capture rates and species richness, with a turnover of some species along the altitudinal gradient in the IDB. Changes in habitat heterogeneity along the elevation gradient are probably one of the strong ecological factors affecting these assemblage parameters. Furthermore, the data from this study allows the expansion of knowledge of the bat species occurring in the region of the IDB. The diversity of species found, together with the occurrence of rare, threatened, and data deficient species highlights the importance of the region for conservation to understand the species distribution patterns. |
