“…Recently, Oliveira & Pêssoa (2005) published a study about the mammal fauna of the Chapada Diamantina, and before that, Gregorin & Mendes (1999) listed 11 species of bats. Bat fossils from the Pleistocene were also registered by Cartelle & Abuhid (1994) and Czaplewski & Cartelle (1998).…”

Chapada Diamantina is located in central Bahia state, and has a large diversity of habitats, including important transitional areas, but has remained largely unstudied until now. In the present study we list the nonflying mammals of Chapada Diamantina National Park and surroundings. We captured only small non-volant mammals, medium and large mammals were assessed through indirect evidences (tracks and marks) and interviews. We recorded 58 species and 47 genera from seven Mammalian orders. Seven species are included in the list of endangered Brazilian species by IBAMA and IUCN; and other seven are classified as data-deficient. Species richness of small mammals was equivalent among sampled habitats, but species composition varied among habitats (10 in semi-deciduous forest, 9 in rocky savanna and 8 in cerrado sensu stricto), as some species are restricted by humidity to forest habitats. During four different samplings, eight species were collected only in open vegetation, four only in forests, and six in both habitats. Oligoryzomys rupestris and Gracilinanus microtarsus had its geographic range expanded. Faunal composition is similar to the one observed in the Atlantic Forest, including species from Cerrado and Caatinga. Besides, some species occupy different habitats from those previously ascribed to them. Keywords: mammal diversity, zoogeography, Cerrado, Caatinga, Atlantic Forest.PEREIRA, L.P. & GEISE, L.

Biota Neotrop., 9(3): http://www.biotaneotropica.org.br/v9n3/en/abstract?article+bn03709032009.Resumo: A Chapada Diamantina está localizada na parte central do Estado da Bahia, apresentando grande diversidade de habitats, assim como áreas de transição. Seu isolamento da Mata Atlântica costeira por extensa área de vegetação aberta fazem com que seja uma região de particular interesse na compreensão dos padrões de ocorrência e evolução da mastofauna neotropical. Uma lista de mamíferos não voadores do Parque Nacional da Chapada Diamantina e arredores foi elaborada. O esforço de captura foi realizado apenas para pequenos mamíferos, assim, a sua composição e riqueza de espécies entre habitats (floresta decidual, cerrado sensu stricto e campo rupestre) foram calculadas. Visitas às coleções científicas permitiram, junto com os dados de coletas, a compilação de 58 espécies e 47 gêneros de sete ordens de mamíferos. Sete espécies estão incluídas nas listas de espécies brasileiras ameaçadas de extinção do IBAMA e do IUCN; e outras sete estão classificadas como espécies com pouco conhecimento. A riqueza de espécies de pequenos mamíferos foi equivalente entre os habitats sem relação com o esforço amostral e número de espécies coletadas (10 na floresta decidual, nove em campo rupestre e oito no cerrado sentido restrito). A composição de espécies de pequenos mamíferos variou entre habitats, já que algumas espécies são restritas a ambientes úmidos e com fitosionomia florestal. Durante os quatro períodos de captura foi observada uma maior afinidade de algu...

Resumo: Eumops perotis apresenta poucos registros confirmados para a América do Sul, distribuídos de forma desigual por quase todos os países do continente. Nesta comunicação, nós relatamos a primeira ocorrência deste molossídeo no Estado do Paraná, Sul do Brasil e sumarizamos as demais localidades conhecidas para o país. Palavras-chave: Chiroptera, Molossidae, distribuição, novos registros, América do Sul.

“…Palaeoenvironmental interpretation of an AMS radiocarbon age of fossil bat bone belonging to a living species that nowadays selects moister habitats suggests a wetter period around 24 000 cal. yr BP (Czaplewski and Cartelle, 1998). For the period 35 000-10 000 cal.…”

2004. Quaternary ecological and geomorphic changes associated with rainfall events in presently semi-arid northeastern Brazil.ABSTRACT: Several geomorphic features and palaeobiotic remains in now semi-arid northeastern Brazil indicate major palaeoenvironmental changes during past periods of increased rainfall. 230 Th mass spectrometric ages of speleothems and travertines have allowed the determination of the timing and duration of wetter than present conditions. The data demonstrate that wet events have occurred throughout much of the Pleistocene, present dry conditions having been established at the end of the Younger Dryas. A markedly different fauna comprising megafaunal elements not adapted to the present low arboreal scrubland caatinga vegetation existed in the area. Palaeobotanical remains embedded in travertine indicate forested vegetation at these wetter intervals, suggesting that the caatinga was then replaced or mixed with a semi-deciduous forest. Due to the abundance of travertine sites containing fossil botanical remains in northeastern Brazil, it is believed that forest expansion occurred over large areas of the now semi-arid zone, showing that the long hypothesised forested links between biodiversity-rich Amazon and Atlantic rainforests may indeed have existed during these moister phases.
