Analysis of 105 scats the maned wolf ( Chrysocyon brachyurus ) collected in central Brazil yielded 304 occurrences food items which fruits Solanum lycocarpum , rodents, and birds accounted for 61.5%. By analysis minimum number individual animals, rodents were 75% a total 156 prey. On other hand, S. armadillos Dasypus spp.) bulk estimated biomass consumption, yielding 63.7% 73.5 kg. Rodents mostly captured during dry season, while miscellaneous consumed wet season. The consumption was...
Transmission of disease between wildlife, domestic animals, and humans is great concern to conservation issues public health. Here we report on the prevalence anti-Leishmania sp. antibodies in 21 wild canids (7 Chrysocyon brachyurus, 12 Cerdocyon thous, 2 Lycalopex vetulus) 74 free dogs (Canis familiaris) sampled around Serra do Cipó National Park. In dogs, apparent was 8.1% it 19% (2 crab-eating foxes, C. maned wolves, brachyurus). Management dog population with evaluation incidence changes...
Individual movements of bats are triggered by their life requirements, limited recognition the environment and risks moving, mediated habitat selection. Mining adds fragmentation heterogeneity to landscapes, with poorly understood consequences activities bats. Cave dwelling spend most cycles within caves, as they constantly forage in external contribution input organic matter caves is paramount importance subterranean biodiversity. We investigated selection cave a mosaic Amazonian forests,...
Trypanosomatids are obligate flagellated parasites, with the genera Leishmania and Trypanosoma acting as etiological agents of significant diseases such leishmaniasis Chagas disease. Although ecological studies have increasingly highlighted role bats potential reservoirs these diversity trypanosomatids in urban bat populations remains poorly understood. This study investigates occurrence Trypanosomatidae from Mangabeiras Municipal Park (MMP), an park Belo Horizonte, Minas Gerais, Brazil, a...
Une communaute de petits mammiferes a ete etudiee dans le sud-est du Bresil septembre 1992 aout 1993. La composition specifique et quelques parametres concernant les especes plus frequentes ont obtenus la foret semidecidue, galerie savane herbeuse. Quatre marsupiaux dix rongeurs captures. sont propres aux deux forets (Caluromys lanatus, Micoureus cinereus, Oecomys concolor Oryzomys capito); cinq especes, (Pseudoryzomys simplex, Oxymycterus roberti, Bolomys lasiurus, subflavus Cavia aperea),...
Tapirs are considered generalist herbivores and the differences in proportions of dietary items often attributed to habitats where individuals live. This study characterized feeding habit Tapirus terrestris (Linnaeus, 1758) a nature reserve south-eastern Brazil, located region transition zone between Cerrado (Brazilian savanna) Atlantic Forest biomes. Fecal samples from T. were collected monthly at six sampling areas that encompassed total 242.22 ha. There 147 fresh found (77 during dry...
From the analysis of 230 scats, diet maned wolves, Chrysocyon brachyurus (Illiger, 1815), was determined in a private natural reserve southeastern Brazil which ecotourism activities are developed and animals deliberately fed bovine meat. A total 569 occurrences food items were recorded, 56.8% animal origin 29.1% vegetal origin. Rodents, insects birds added up to 35.8% occurrences, yet accounted for 68.5% number preys (277). Insects, however, had practically no importance (0.1%) estimated...
A population of the Neotropical marsupial Didelphis albiventris (Lund, 1840) living in an urban forest fragment was studied. Population structure and influence sex age on two variables related to habitat use (Daily home range - MCP Habitat intensity UI) obtained by spool-and-line technique were analysed. There 20 males 29 females studied (N = 49). No sexual dimorphism apparent adult individuals. 16 24 tracked using device. significant differences found mean size daily range, which greater...
Abstract The occurrence of anomalous coloration (albinism, leucism and melanism) in mammals is a rare phenomenon nature, but this has been reported for several species mammals. In study, we report on the Eira barbara by examining three road-killed individuals two sightings live animals Reserva Particular do Patrimônio Natural Santuário Caraça, southeastern Brazil. addition, examined tayra specimens housed mammal collections from Brazil USA. found dead those sighted had whitish yellow fur...
The Serra do Caraça Reserve is situated in the southern portion of Espinhaço Mountain Range, and contains areas "campos de altitude", "cerrado" atlantic forest. This study had as its objective registering bats species that occur reserve. data collection was carried out one year through monthly samplings, using mist nets set on trails, also hand capture. A total 246 individuals were collected (0.72 bats/net-hour), distributed across 15 species, belonging to families Phyllostomidae (83.0%;...
Species richness and abundance of bats were studied in four nature reserves, including a karst area which has many potential rocky shelters for bats, such as caves rock crevices. The reserves located the greater Belo Horizonte metropolitan area, one most populated regions Brazil, within Atlantic Forest, Cerrado (Brazilian savanna) ecological domains. Bats sampled using mist-nets and, also by active searches shelters. A total 1,599 captured representing 30 species belonging to families. There...
With a nearly global distribution the vespertilionid bat Myotis represents one of most exceptional examples adaptive radiation among mammals. We investigated reproductive activity yellowish myotis, levis, from highland area in Southeastern Brazil. The data were obtained through histological analyses male and female genital systems February 2010 to May 2011. testes adult myotis showed seasonal morphological characteristics which categorized following stages: rest, maturing, mature, mating....
Since bats shelter in roosts during their period of diurnal inactivity, the quality and availability are important aspects ecology. Karst areas have great potential for day roosts, since they form caves, which serve as bat shelters. Here we characterize caves used by a preserved karst area Southeastern Brazil. Using logistic regression analysis identified cave characteristics that influence occupation. Sixty-six were characterized based on measurements internal height width, width...
Yellowish myotis, Myotis levis, is a seasonal, epididymal sperm-storing Neotropical vespertilionid. In the dry season, males show simultaneous testis regression and sperm storage in cauda epididymis, enabling them to mate during this season. study, we investigated seasonal variations body mass, diameter height of seminiferous tubules nuclei Leydig cells population southeastern Brazil. We also determined frequencies stages epithelium cycle (SEC) mature individuals population. Body mass cell...
The large fruit-eating phyllostomid bat, Artibeus lituratus (Olfers, 1818), forearm 69-75 mm, body mass 66-82 g, has a diversified geographic distribution in the Neotropical region. Therefore it is subjected to different climatic conditions that affect its reproduction, leading reproductive strategies such as continuous seasonal monoestry or bimodal polyestry. In this study we used morphometric and histological methods analyze annual activity of A. males population living Atlantic Forest,...
We present here a compilation of the mammal species associated with Reserva Particular do Patrimônio Natural (RPPN) Santuário Caraça. From records confirmed by captures, visual observations, and indirect evidence we list 70 mammals, including Alouatta guariba, Chrysocyon brachyurus, Leopardus pardalis, wiedii, Pecari tajacu, Puma concolor, Tapirus terrestris Trinomys moojeni that are considered to be threatened according Red Lists (Minas Gerais, Brazil, IUCN) nine endemic Atlantic Forest....
Abstract The reproductive activity of two species wild rodents was studied in the Serra do Rola‐Moça State Park (PERM), state Minas Gerais, Brazil. From October 1998 to 1999 specimens Akodon montensis (Thomas 1913) were captured an area seasonal semi‐deciduous forest, while Bolomys lasiurus (Lund 1840) a cerrado (a savannah‐like grassland). determination condition based on histological and histometric analyses testes external characteristics gonads. volume testes, diameter seminiferous...
