          Abstract

          Biodiversity corridors comprise a mosaic of land uses connecting fragments of natural forest across a landscape. Two such corridors have been established along the eastern coast of Brazil: the Serra do Mar and the Central da Mata Atlântica corridors, along which most of the coastal plains are restinga areas. In this study, we analyze the present status of the endemic and endangered terrestrial vertebrates of both corridors. We sampled 10 restingas in both corridors, recording species of amphibians, reptiles, birds, and mammals. Some restingas harbor a relatively large number of endemic species, and two main regions of endemism can be identified along the restingas of both corridors: the coastal restingas from northern Espírito Santo State to southern Bahia State (between Linhares, ES, and Trancoso, BA), and the coastal region between the restingas of Maricá and Jurubatiba, Rio de Janeiro State. Six species of terrestrial vertebrates considered threatened with extinction are found in the restingas of Serra do Mar and Central da Mata Atlântica biodiversity corridors (Liolaemus lutzae, Formicivora littoralis, Mimus gilvus, Schistochlamys melanopis, and Trinomys eliasi). The region located between the restinga of Maricá and that of Jurubatiba is of special relevance for the conservation of vertebrate species of the restingas of the corridors because a considerable number of threatened species of terrestrial vertebrates are found there. We strongly recommend efforts to develop checklists of threatened faunas for the States of Espírito Santo and Bahia.

          Corredores de biodiversidade compreendem um mosaico de usos do solo conectando fragmentos de vegetação natural ao longo da paisagem. Ao longo da costa leste do Brasil, dois corredores de biodiversidade foram estabelecidos: o da Serra do Mar e o Central da Mata Atlântica. A maioria das planícies costeiras ao longo desses dois corredores é constituída por restingas. Neste estudo analisamos o status atual das espécies de vertebrados terrestres endêmicas e ameaçadas nos dois corredores. Amostramos dez restingas nos dois corredores, registrando a ocorrência de espécies de anfíbios, répteis, aves e mamíferos. Algumas restingas apresentam número relativamente alto de espécies endêmicas e duas regiões principais de endemismos podem ser reconhecidas nas restingas ao longo dos corredores: as restingas costeiras do norte do Espírito Santo até o sul da Bahia (entre Linhares, ES, e Trancoso, BA) e a região costeira entre as restingas de Maricá e Jurubatiba, Estado do Rio de Janeiro. Seis espécies de vertebrados terrestres consideradas ameaçadas de extinção foram encontradas nas restingas dos corredores da Serra do Mar e Central da Mata Atlântica (Liolaemus lutzae, Formicivora littoralis, Mimus gilvus, Schistochlamys melanopis e Trinomys eliasi). A região localizada entre as restingas de Maricá e Jurubatiba é de especial relevância para a conservação de espécies de vertebrados das restingas nos corredores, pois nela foi encontrado elevado número de espécies ameaçadas. Recomendamos esforços para a elaboração de listas de fauna ameaçada para os Estados do Espírito Santo e Bahia.

              Molecular phylogeny of the genus Oryzomys (Rodentia: Sigmodontinae) based on cytochrome b DNA sequences.

              The genus Oryzomys comprises 40 species arranged in several species groups. To test the monophyly of three Oryzomys species groups ("capito," nitidus, and subflavus), we analyzed, by distance, parsimony, and maximum-likelihood (ML), 801 bp of the mitochondrial gene cytochrome b. Our results did not sustain the monophyly of Oryzomys nor of the nitidus and subflavus species groups. Within the "capito" species group, O. perenensis appeared as a valid species, as a sister branch of the clade formed by O. megacephalus and O. laticeps. Within the nitidius species group, only the association between O. nitidus and O. lamia was well supported. The subflavus species group split into two clades: one with O. subflavus karyomorphotypes and another grouping O. angouya with species of different genera in the parsimony, distance, and ML trees.
