Primeiro registro do morcego Mimon crenulatum (Phyllostomidae) no Pantanal, sudoeste do Brasil

Abstract

Species of Mimon Gray, 1847, are known to occur from Mexico to central Bolivia and southeastern Brazil, ranging from 22 o N to 25 o S of latitude. In latitudes between 14 and 25 o S, approximately, the known occurrence of Mimon is restricted to east Brazil, in the Atlantic rainforest. Only in latitudes lower than 14 o S the species of Mimon additionally occurs in central and western South America, in the Amazon, Cerrado and Caatinga. Mimon crenulatum (E. Geoffroy, 1810) is locally uncommon but widespread over the range of the genus distribution. We report here the occurrence of M. crenulatum at ca. 20 o S of latitude in the Pantanal wetlands, western Brazil. It is probably the first record of the genus Mimon in this ecosystem, and it increases the geographic range of M. crenulatum distribution to western Brazil in latitudes greater than 14 o S.

Bat-species richness in the Pantanal floodplain and its surrounding uplands

“…Recent literature has synthesised the number of species and distribution in Brazil (Reis et al, 2007), as well as a bat community in a savanna habitat in Bolivia, near the Pantanal Aguirre, 2002). Available data on bats of the Pantanal floodplain and its neighbouring uplands, particularly from Mato Grosso do Sul state, are reported in Leite et al (1998Leite et al ( , 2000, Taddei et al (2000Taddei et al ( , 2001Taddei et al ( , 2003, Camargo and Fischer (2005), Gonçalves et al (2007), Longo et al (2007), Camargo et al (2009), and Teixeira et al (2009.…”

Terrestrial and aquatic mammals of the Pantanal

“…Here we update this number to 170 mammal species in the Brazilian Pantanal, and to 174 species including the Pantanal floodplain in Northeastern Paraguay (Willig et al, 2000). The increased number of species reviewed here is partially related to constant progress in taxonomic revisions, especially with the support of cytogenetics to identify new species of small mammals (wild rodents and marsupials), and to the recently increase of surveys on bats -by far the richer order of mammals in the Pantanal (Figure 1) (Camargo and Fischer, 2005;Longo et al, 2007;Santos et al, 2010). Despite several mammal species being conspicuous in the Pantanal, like capybara -a symbol of the Pantanal -most of the mammal species are not easily recorded, as they present nocturnal and twilight habits.…”

“…Joining the available information, we approach comprehensive patterns of mammalian ecology, combining habitat features and species interactions in search of unifying trends for the species, populations and communities to the drastically seasonal habitats. The relevant literature on species occurrence, community composition, population densities, habitat preference, and interspecific relations of mammals in the Pantanal was surveyed.The reviewing of records of Pantanal mammals was based on previous revisions and additional scientific literature and technical reports (Marinho-Filho and Sazima, 1998; Wilig et al, 2000;Oliveira et al, 2002;Rodrigues et al, 2002;Camargo and Fischer, 2005;Longo et al, 2007;Marinho-Filho, 2007;Carmignotto, 2004;Cáceres et al, 2008;Aragona and Marinho-Filho, 2009;Tomás et al, 2010). Species names follow Wilson and Reeder (2005) and Reis et al (2006); classes of extinction threats follow the International Union for Conservation of Nature (IUCN) and the Livro Vermelho da Fauna Brasileira Ameaçada de Extinção (IBAMA) of the Ministério do Meio Ambiente (Brazilian Ministry of the Environment).…”

Ocorrência de Vampyressa pusilla (Chiroptera, Phyllostomidae) no Pantanal sul

“…Paraguai em oposição à idéia atual de que representa região de disjunção (Pedro et al 1997, Lim et al 2003. Adicionalmente, os registros de V. pusilla no Pantanal ampliam para 62 o número de espécies de morcegos listadas para este ecossistema (Marinho-Filho & Sazima 1998, Camargo & Fischer 2005.…”

“…Espécies de Vampyressa são localmente raras e amplamente distribuídas, ocorrendo desde o sul do México até o sul do Peru, assim como na bacia Amazônica, sudeste da América do Sul e sul do Paraguai (Lewis & Wilson 1987, Miretzki 2003. As espécies de Vampyressa e de alguns outros gêneros de morcegos neotropicais apresentam distribuição geográfica disjunta devido à provável não ocorrência em formações áridas na região central da América do Sul (Lewis & Wilson 1987, Camargo & Fischer 2005. A ausência de registros no Pantanal determina a separação das distribuições de V. pusilla (Wagner, 1843) e V. thyone Thomas, 1909 -anteriormente consideradas uma mesma espécie (Koopman 1993, Nogueira et al 1999, Lim et al 2003.…”
