An especially interesting question is “How many species of bats can be found simultaneously in the same cave?” This information is surprisingly rare in the literature, mainly in the Neotropics. The aim of this study was to sample bats in Gruta do Limoeiro cave, Municipality of Castelo, State of Espírito Santo, Brazil after a 53-year interval of the first survey, by the naturalist Augusto Ruschi. Four surveys were conducted in 2005 and 2006, capturing bats with mist-nets and actively exploring the cave. We recorded eleven species of three families, Phyllostomidae, Vespertilionidae and Molossidae, making Gruta do Limoeiro cave one of the most diverse caves in the World for bats. Of the 14 species found by Ruschi, seven were still present, and four species were added. The seven species lost from Ruschi’s list are mainly Emballonuridae and some Phyllostomidae, probably due to landscape changes. We recommend the long-term monitoring of the Gruta do Limoeiro cave to understand the loss in diversity, and consequently in ecosystem services.

Chiropterofauna (Mammalia: Chiroptera) from the Altamiro de Moura Pacheco State Park, Goiás, Brazil

The Brazilian Cerrado is undergoing important changes. It is estimated that 70% of its natural area has converted to human use. The loss and fragmentation of natural habitats is considered the main cause of species loss in ecosystems. However, the lack of knowledge of biodiversity makes it difficult to design effective conservation measures. This article presents a list and an estimate of the richness of bats in the Parque Estadual Altamiro de Moura Pacheco (PEAMP) in Goiás. All collected bats belong to the Phyllostomidae family, with Carollia perspicillata (67%) and Artibeus planirostris (18%) representing 86% of the captured individuals.

The effect of urbanization on species composition and trophic guilds of bats (Mammalia, Chiroptera) in the Brazilian Savanna

Urban environments present less environmental heterogeneity in relation to the natural ones, affecting the biodiversity of bats and the ecological processes in which they participate. In this way, we will identify how urbanization influences the structure of bat communities in the municipality of Goiânia, Goiás, Brazil. We compared species composition, guilds and bat richness in a gradient that crossed urban, semi-urban and natural areas in the municipality of Goiânia, contained in the Cerrado biome. We captured a total of 775 bats of 16 species distributed in three families. Urban areas had a higher species abundance, while semi-urban areas had a higher species richness. The three types of environments have different compositions, the urban one being more homogeneous, the fauna in these areas is composed of generalist species, which benefit from this process. The diversity present in semi-urban areas is a consequence of the intersection between urban and natural fauna, which is why urban expansion needs to occur in a planned manner to minimize the impacts of this process and ensure the maintenance of biodiversity.
