“…In regard to frequencies of mammals in natural habitats and roads, some species typical of the savannas were most common in the Cerrado ecoregion, as expected from other regional (SANTOS-FILHO & DA SILVA 2002, ROCHA & DALPONTE 2006, CÁCERES et al 2007) and large-scale studies (FONSECA et al 1996, EMMONS & FEER 1997, EISENBERG & REDFORD 1999. A main example of typical savannah species in the Cerrado ecoregion is the giant anteater M. tridactyla, besides some rare species such as the maned wolf C. brachyurus, and two armadillo species -Cabassous unicinctus (Linnaeus, 1758) and P. maximus.…”

“…We adopted this threshold in order to avoid bias, since not all sites had trails or soil characteristics that allowed us to find animals through their footprints, since tracking was the main sampling method used here (see CÁCERES et al 2007). Each site was surveyed either once or twice (each time in a different season).…”

“…The main systematic surveys were as follows: Small mammal species such as those in Didelphis Linnaeus, 1758 (± 1 kg in body mass) were included in the habitat analyses because they are easy to identify in the field based on footprints (BORGES & TOMÁS 2004). The species of Didelphis most commonly found in the study region is D. albiventris Lund, 1840(CÁCERES et al 2007. Primates were also included because they are easy to record in transect lines and the different species can be identified through their vocalization patterns (EMMONS & FEER 1997).…”

This paper examines the frequencies of mammal roadkill in two adjacent biogeographic ecoregions (Atlantic Forest and Cerrado) of Brazil. Mammals were recorded during a seven-year period and over 3,900 km of roads, in order to obtain data for frequencies of species in habitats (sites) and frequencies of species killed by cars on roads. Sites (n = 80) within ecoregions (Cerrado, n = 57; Atlantic Forest, n = 23) were searched for records of mammals. Species surveyed in the entire region totaled 33, belonging to nine orders and 16 families. In the Cerrado, 31 species were recorded in habitats; of these, 25 were found dead on roads. In the Atlantic Forest ecoregions, however, we found 21 species in habitats, 16 of which were also found dead on roads. There was no overall significant difference between ecoregions for frequencies of occurrence in habitats or for roadkills, but there were differences between individual species. Hence, anteaters were mostly recorded in the Cerrado ecoregion, whereas caviomorph rodents tended to be more frequent in the Atlantic Forest ecoregion (seen mainly by roadkills). The greater number of species (overall and threatened) and the greater abundance of species records in the Cerrado suggest that this ecoregion has a greater biodiversity and is better conserved than the Atlantic Forest ecoregion, in the state of Mato Grosso do Sul, south-western Brazil

“…Um maior número de espécies pertencentes à ordem Carnivora é frequente em estudos no Cerrado, revelando a ocorrência entre 30 a 57% do total amostrado; porém com registros pouco frequentes (Schneider et al 2000, Santos-Filho & Silva 2002, Cáceres et al 2007, Oliveira et al 2009, Rocha & Silva 2009). Essa ordem é representada por 20 espécies, correspondendo a 42,5% da mastofauna de médio e grande porte no bioma (Marinho-Filho et al 2002), sendo a mais representativa também na área de estudo.…”

Composition and diversity of medium and large size mammals in the Cerrado of central Brazil. Studies about medium-and large sized mammals (≥ 1.0 kg) in disturbed areas in the Cerrado showed that many species are adapted to anthropogenic environments. We investigated the structure of mammals assemblages in an area of 92,000 ha located in southwest of Bahia and covered by plantations of Pinus spp., soybeans and conserved strips of cerrado sensu stricto. The mammals were recorded in nine sampling campaigns of 12 days between January/2008 and May/2009 in diurnal and nocturnal transects that varied 5-15 km in length per campaigns totaling 3,600 km traveled/period. In this area 29 species were recorded, 23 through the line transect and others outside transect by indirect observation, capture and previous records. The mammal community consists mostly of representatives of the Carnivora (41.4%) and omnivore species (36.7%). The only endemic species of Cerrado recorded in the area was hoary fox, Lycalopex vetulus. Only 13.6% of species were present in all sampling (Ozotoceros bezoarticus, Pecari tajacu and Tolypeutes tricinctus) and seven of which correspond to 91.73% of the records made. The species that had largest number of records (23.76%) is three-banded armadillo (T. tricinctus), probably this area holds the largest population of this endangered species in biome, highlighting the importance of avoiding areas of native vegetation are replaced by monocultures and reforestation. Many of the species recorded are generalists in habitat use and widely distributed throughout the biome, occurring even in disturbed habitats. The maintaining of observed diversity in this area is due to its large size and the mosaic of environments that provide a greater variety and diversity of resources such as shelter and food, allowing also the presence of species with low densities and specialists in the diet and habitat. Keywords: altered landscape, community structure, feeding guilds, linear transect, richness. Resumo: Composição e diversidade de mamíferos de médio e grande porte no Cerrado do Brasil central. Estudos com mamíferos de médio e grande porte (≥1,0 kg) em áreas alteradas no Cerrado revelam que muitas espécies se adaptam aos ambientes antropizados. Foi investigada a estrutura da comunidade de mamíferos em uma área de 92.000 ha localizada no sudoeste baiano e constituída por plantios de Pinus spp., soja e faixas de cerrado sentido restrito. Os mamíferos foram registrados ao longo de nove campanhas de 12 dias, entre janeiro/2008 e maio/2009, no período diurno e noturno através de transectos lineares variando entre 5-15 km de extensão e que totalizaram 3.600 km percorridos/ período. Foram registradas 29 espécies, sendo 23 através dos transectos lineares e as demais por observação indireta, captura e registros pretéritos. A comunidade é constituída em sua maioria por representantes da ordem Carnivora (41,4%) e espécies onívoras (36,7%), sendo Lycalopex vetulus a única espécie endêmica do Cerrado registrada na área.
