ABSTRACT. Here we present an extensive survey for non-volant mammals along the margins of the Jequitinhonha River, which represents a contact area between the Cerrado and Atlantic Forest biomes. Our data were ob- tained after 13 trapping expeditions (from 2005 to 2012) on both banks of the river, from its sourcetoits mouth, enriched by data obtained from a literature review and voucher specimens deposited in six mammal collections. All collected specimens were identified through their karyotypes and/or morphology. We obtained data for 75 localities (34 at the rigth margin, 42 at the left margin; 30 in the Cerrado and 45 in the Atlantic Forest). We obtained voucher records for 91 species, ca. 17% of all known Brazilian terrestrial non-volant mam- mals. Our results include range extensions for six species (Monodelphis scalops, Thylamys velutinus, Calomys mattevii, Wiedomys pyrrhorhinos, Galea spixii, Kerodon rupestris), and karyotype information for 26 species (11 marsupials and 15 rodents), with four new karyotypes. While most species have wide geographical range in both biomes, 26 were recorded only in the Cerrado and 19 were recorded only in the Atlantic Forest. Recorded species represent 28.7% (6.3% endemic) of the species known from the Cerrado and 21.5% (22.2% endemic) of those from the Atlantic Forest. The richness of the fauna recorded in this region supports its importance for the understanding of mammal biogeography, diversity and evolution.

RESUMO. Mamíferos terrestres da bacia do Rio Jequitinhonha, Brasil: uma área de transição entre a Flo- resta Atlântica e o Cerrado. Aqui apresentamos uma extensa pesquisa de mamíferos não-voadores ao longo das margens do Rio Jequitinhonha, região biogeográfica interessante que representa uma área de contato entre dois biomas brasileiros (Cerrado e Mata Atlântica), ainda pouco conhecidos para a fauna de mamíferos. Nossos dados foram obtidos após 13 expedições de captura (de 2005 a 2012), em ambas as margens do rio, da nascente até à foz, enriquecida por dados obtidos a partir de amostras de material depositado em seis coleções de mamíferos. Todos os espécimes coletados foram identificados através de seus cariótipos ou morfologia. Foram obtidos dados

Enquanto a maioria das espécies têm ampla distribuição geográfica, 26 ocorreram apenas no Cerrado e 19 apenas na Mata Atlântica.

INTRODUCTION The Jequitinhonha River Basin appears to be a particularly interesting region because it Brazil is the largest country in the Neotropics runs into both Atlantic Forest and Cerrado. and it has the largest mammal diversity in The vegetation along the Jequitinhonha River the world, with over 700 known species, a Basin changes along the river path. The region number that has been steadily increasing in is formed by a mosaic of vegetal physiognomies the past decades (Costa et al., 2005; Paglia et presented in two biomes (Cerrado and Atlantic al., 2012).

Thus, such of Brazilian mammal species, given the exten- an environmental heterogeneity is likely to reveal sion of the country, was by far underestimated a peculiar mammalian fauna composition, as it is (Vivo, 1997). These facts only strengthen the surrounded by regions that harbor each a distinct importance of comprehensive and exhaustive mammal composition (Lessa and Paula, 2014). surveys, particularly in those regions that have Additionally, this sequence of vegetation also been poorly sampled, in order to accurately includes contact zones, where several mammal evaluate their species composition (Patterson, species from more than one of these biomes can 2002; Costa et al., 2005; Lessa et al., 2008). be found in sympatry (Geise and Astúa, 2009).

Levels of endemism in Brazil are for non-volant mammals in both riverbanks high, with ca. 30% of the recorded mammal of the Jequitinhonha River Basin, representing species being endemic (Paglia et al., 2012).

Terrestrial mam- mal species richness recorded in Jequitinhonha River Basin represents 17% of all known ter- restrial species in Brazil, not considering Calassomys apicalis, described after Paglia et al. (2012). Most recorded species (91) have a wide geographical distribution range and

APPENDIX I Gazetteer with geographical and vegetation information for localities from Jequitinhonha River Basin with mammal registers, arranged from the source to the mouth region of the river. Under- lined names = municipalities. Number before locality name corresponds to localities plotted in Fig. 1. Localities with our collecting effort are in bold. nln = no locality name. When coordinates of a locality were not found we used coordinates of the municipality. After coordinates, vegetation type (IBGE 2012): Agrarian Activities (originally Savanna, Steppic Savanna/Seasonal Forest or Savanna/ Broadleaf Forest) = AA; Arboreous Savanna = AS; Arboreous Steppic Savanna = ASS; Grassy-Woody Savanna = GWS; Mangroves = MA; Moist Broadleaf Forest of Lowlands = MBFL; Savanna/ Broadleaf Forest = S/BF; Savanna/Seasonal Forest = S/SF; Seasonal Decidual Submontante Forest = SDSF; Secondary Vegetation and Agrarian Activities (originally Seasonal Decidual, Semi- deciduous or Moist Broadleaf Forests) = SV/AA; Upper Montane Vegetational Refuges = UMVR.
