“…Medium and large mammals were identified in the field using Emmons & Feer (1997), Eisenberg & Redford (1999) and Reis et al (2006). Taxonomic nomenclature follows Wilson & Reeder (2005), as well as Bonvicino & Moreira (2001), Bonvicino et al (2002), Costa et al (2003), Weksler et al (2006), Reis et al (2006) and Bonvicino et al (2008). Conservation status follows Machado et al (2008) Voucher specimens (skull, skin and partial skeleton) were deposited at Museu Nacional do Rio de Janeiro (MN) and Museu de Zoologia da Universidade de São Paulo (MZUSP) (see Appendix).…”

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...

“…Recently, different species were described among specimens previously identified as O. subflavus, through morphologic analysis, studies with DNA sequences and chromosomal data (Andrades-Miranda et al, 2002;Bonvicino et al, 1999;Bonvicino and Moreira, 2001;Langguth and Bonvicino, 2002). All these species present different karyotypes, which may be derived from one another by a small number of chromosome arrangements (Bonvicino et al, 1999).…”

The Chapada Diamantina (CD) is located in Bahia State, between 11-14° S and 41-43° W, being part of the Serra do Espinhaço. The occurrence of different habitats and transition areas permits an interesting mammal fauna composition, with species from different biomes living in sympatry. Species of Didelphimorphia and Rodentia are important members of mammal communities in almost all different habitats, and morphological and cytogenetic characters are important for a correct identification of most of these species. In this work 258 specimens of small mammals from the orders Didelphimorphia (six genera and six species) and Rodentia (two families, five Sigmodontinae tribes, nine genera and 11 species) were collected during the whole field work (44 nights

“…Several reports on the systematic of this tribe, with emphasis on the traditional conception of the polyphyletic genus Oryzomys (Musser and Carleton, 2005), resulted in more accurate definitions of genera, species group, and species in the past decade (Weksler, 1996;Musser et al, 1998;Percequillo, 1998Percequillo, , 2003Bonvicino and Moreira, 2001;Langguth and Bonvicino, 2002;Musser and Carleton, 2005;Weksler, 2003Weksler, , 2006. These studies led to the recent division of Oryzomys species groups in 10 new oryzomyine genera: Aegialomys, Cerradomys, Eremoryzomys, Euryoryzomys, Hylaeamys, Mindomys, Nephelomys, Oreoryzomys, Sooretamys and Transandinomys .…”

Cerradomys is a monophyletic genus that includes four known species, Cerradomys subflavus, C. maracajuensis, C. marinhus, and C. scotti, distributed throughout the open vegetation belt across South America, from northeastern Brazil to southeastern Bolivia, and from eastern to northwestern Paraguay. We revised the status of the species currently assigned to this genus by analyzing skins, skulls, karyotypes, and cytochrome b DNA sequences. We also described two novel species, one distributed in the Brazilian states of Minas Gerais, Bahia, and Sergipe, and the other in the states of Paraíba,
