“…(2003) and Anonymous (2008a). We collected data from the following museums and scientific collections: Museum of Zoology of University of São Paulo (MZUSP; also visited by one of the authors), National Museum of Rio de Janeiro (MNRJ; including personal communication from Sérgio Maia Vaz), American Museum of Natural History (AMNH; online access at http://entheros.amnh.org/db/emuwebamnh/index.php), The Museum of Vertebrate Zoology at Berkeley (MVZB; online access at http://mvz.berkeley.edu/Collections.html) and species, localities, specimens and catalogue numbers listed by da Cunha Vieira (1955), Cabrera (1957, 1961), Wetzel and Ávila‐Pires (1980), Wetzel (1985), Anderson and Handley Jr (2001), Vaz (2001, 2003a, b, 2005a, b) and Lorenzutti and Almeida (2006). Field notes and other unpublished data collected by the authors were compiled from 1994 onwards.…”

ABSTRACTm am_188 35..54 1. The endemic maned sloth Bradypus torquatus is globally threatened due to deforestation, habitat fragmentation and isolation of populations. Despite increased interest in the species in recent years, information on its geographic distribution is limited and is derived mainly from a few museum species and from a survey based mostly on interviews carried out more than 20 years ago. Information on its habitat and altitudinal preferences is lacking. We therefore compile, update and review all occurrence records of this species using geographical information system (GIS) tools and produce a distribution map for the species. 2. Our compilation totalled 188 occurrence records, of which 130 (69%) were considered confirmed (museum specimens or individuals captured or seen in the field), most of which (62%) were restricted to the states of Bahia and central-south Espírito Santo (29%). The species occurs predominantly in ombrophilous forest (80%), from sea level to 1290m, but mainly (79%) below 200m altitude. 3. We used GIS techniques and the alpha shape algorithm to calculate the extent of occurrence of the species and compared the resulting map with distribution maps available in the literature. We found a great deal of variation in distribution area shape and an almost two-fold variation in distribution area size among sources. 4. We confirmed the existence of a main distribution gap between southern Bahia and northern Espírito Santo and discovered a second smaller gap between southern Espírito Santo and northern Rio de Janeiro. 5. We also confirmed that B. torquatus is sympatric with the common three-toed sloth Bradypus variegatus in a large part of the Atlantic forest and that the two species are syntopic in at least 11 locations.

“…Ten faunal lists were used for comparison, including five Quaternary fossils sites and five extant ecosystems. The latter include three areas of ombrophilous dense forest (Vaz, 2005), two of which are near Abismo Iguatemi (Pianca, 2001;Instituto Ambiental do Paraná , 2002, p. VI 22-27), as well as two savannah areas, one in the state of Sã o Paulo (Lyra-Jorge and Pivello, 2005;Talamoni, 1996) and another in Central Brazil (Passamani, 2004). Out of the fossil assemblages used for comparison, three are located in the municipality of Iporanga, near Abismo Iguatemi (Ameghino, 1907;Paula-Couto, 1973;Lino et al, 1979;Barros Barreto et al, 1982), and two in areas presently covered by savannah in Central Brazil (SouzaCunha and Guimarã es, 1982; Salles et al, 1999).…”

The Quaternary vertebrate fauna record of South America is characterized by the predominance of mammals, and the study of cave deposits can provide important information on their diversity and distribution. In Brazil, cave deposits have preserved remarkable fossil remains, including both large and small vertebrates, although the former have been the focus of most paleontological works. The fossils studied here came from Abismo Iguatemi, a karstic fissure located in the municipality of Apiaí, upper Ribeira River valley, Sã o Paulo, Brazil. Blocks of sediment collected from its floor yielded a large sample of micro-remains, mainly composed of fragmentary small vertebrate specimens. Taphonomic parameters suggest that the fossil elements entered the cave either by entrapment or transported by rain runoff, as partially decayed carcasses or isolated elements. A total of 35 taxa were recorded in Abismo Iguatemi, four of which are extinct. The number of identified specimens per taxon (NISP index) is the best estimator of number of individuals at the burial site. The comparison of this fauna to that of other Quaternary deposits and to the present biodiversity of different areas reveals low similarity. The identification of fossil organisms with different ecological requirements (extinct savannah organisms and extant dense-forest organisms) suggests the existence of time averaging and may reflect environmental changes in the vicinity of the cave during the late Pleistocene and Holocene.

“…Gracilinanus microtarsus is solitary, nocturnal, and inhabits the Atlantic rain forests and semideciduous forests interspersed in the highly seasonal cerrado in southeastern and southern Brazil (Cherem et al 2004;Gargaglioni et al 1998;Kasper et al 2007;Lyra-Jorge and Pivello 2001;Martins et al 2006a;Pardini et al 2005;Pardini and Umetsu 2006;Passamani 2000;Vaz 2005). G. microtarsus was shown to be associated with locations with reduced canopy cover, being captured in 2nd-growth forests and disturbed fragments of habitat (Piittker et al 2008b).…”

Gracilinanus microtarsus (J. A. Wagner, 1842), called the Brazilian gracile opossum, is a small didelphid that is 1 of 6 species in the genus Gracilinanus. It is a sexually dimorphic, solitary marsupial that has a highly seasonal reproductive pattern. It inhabits Atlantic rain forests and semideciduous forests interspersed in the highly seasonal cerrado (savanna-like vegetation) in southeastern and southern Brazil. It prefers locations associated with low canopy cover and it also occurs in habitats altered by anthropogenic events. The species is classified as Least Concern by the International Union for Conservation of Nature and Natural Resources.
