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 to different reproductive strategies such as continuous reproduction, seasonal monoestry or seasonal bimodal polyestry. In this study we used morphometric and histological methods to analyze the annual reproductive activity of A. lituratus males in a population living in the Atlantic Forest, Southeastern Brazil. Testis mass, epididymis mass, gonadosomatic index, seminiferous tubule diameter, and Leydig cell nucleus diameter showed no significant differences (p > 0.05) in the two...

Tapirs are considered generalist herbivores and the differences in the proportions of dietary items are often attributed to differences in the habitats where individuals live. This study characterized the feeding habit of Tapirus terrestris (Linnaeus, 1758) in a nature reserve in south-eastern Brazil, located in a region considered a transition zone between the Cerrado (Brazilian savanna) and the Atlantic Forest biomes. Fecal samples from T. terrestris individuals were collected monthly at six sampling areas that encompassed a total of 242.22 ha. There were 147 fresh samples found (77 during the dry season and 70 during the wet season). The diet of the tapirs in this reserve was characterized by the prevalent browsing on leaves and stems. There was a low...

The objective of this study was to investigate some parameters of the space use by individuals in a population of the hystricognath rodent Thrichomys apereoides (Lund, 1839), using the spool-and-line tracking technique. This technique is useful for investigating characteristics of habitat use by individuals since it allows the mapping of the places where the individuals move. We evaluated three parameters of space use by 34 individuals of T. apereoides: 1) The daily home range (DHR) or the area used by individuals in their daily activities, 2) the distance moved on the leaf litter, and 3) the distance moved above ground using twigs, logs and rocks. The analysis of space use on such a small scale allows a better understanding of how individuals perceive and...

ABSTRACT. Since bats shelter in roosts during their period of diurnal inactivity, the quality and availability of roosts are important aspects of their ecology. Karst areas have great potential for the availability of day roosts, since they form caves, which serve as bat shelters. Here we characterize the caves used by bats in a preserved karst area of Southeastern Brazil. Using logistic regression analysis we identified the cave characteristics that influence bat occupation. Sixty-six caves were characterized based on measurements of internal height and width, height and width of the entrance(s) of the cave, number of entrances, maximum horizontal development of cave, and internal temperature and humidity. In nineteen months we found 14 species in 32...

A population of the Neotropical marsupial Didelphis albiventris (Lund, 1840) living in an urban forest fragment was studied. Population structure and the influence of sex and age on two variables related to habitat use (Daily home range - MCP and Habitat use intensity - UI) obtained by the spool-and-line technique were analysed. There were 20 males and 29 females studied (N = 49). No sexual dimorphism was apparent in adult individuals. There were 16 males and 24 females tracked using the spool-and-line device. There were significant differences found in the mean size of the daily home range, which was greater in adults than in sub-adults. Regarding the habitat use intensity there were also significant differences related to age. There were no significant...

The Serra do Caraça Reserve is situated in the southern portion of the Espinhaço Mountain Range, and contains areas of "campos de altitude", "cerrado" and atlantic forest. This study had as its objective the registering of the bats species that occur in the reserve. The data collection was carried out in one year through monthly samplings, using mist nets set on trails, and also through hand capture. A total of 246 individuals were collected (0.72 bats/net-hour), distributed across 15 species, belonging to the families Phyllostomidae (83.0%; nine species), Vespertilionidae (12.5%; three species) and Molossidae (4.5%; three species). The most abundant species were Sturnira lilium (E. Geoffroy, 1810) (n = 121, 60.5%), Myotis nigricans (Schinz, 1821) (n = 21,...

This article presents a simple, safe and efficient method for the capture and chemical immobilization of three species of wild canids from the Serra do Cipó National Park region, in the Cerrado biome of Southeastern Brazil. Morphological measurements and anesthesia data obtained during the captures are also described. Such data are essential due to the necessity for invasive research for monitoring programs, clinical cases analysis, and ecological or epidemiological investigations in wild or captive Neotropical canid populations.

From the analysis of 230 scats, the diet of the maned wolves, Chrysocyon brachyurus (Illiger, 1815), was determined in a private natural reserve in southeastern Brazil in which ecotourism activities are developed and the animals are deliberately fed bovine meat. A total of 569 occurrences of food items were recorded, of which 56.8% were of animal origin and 29.1% of vegetal origin. Rodents, insects and birds added up to 35.8% of the occurrences, yet accounted for 68.5% of the total number of preys (277). Insects, however, had practically no importance (0.1%) in the total estimated biomass consumed. Even though the fruit Solanum lycocarpum St.-Hil. is a common food item in the diet of the maned wolf, its occurrence in the diet at the Serra do Caraça Reserve...

Descriptions of Sciurus ingrami Thomas, 1901 nests are not available in the literature. In this study, a survey was made of the distribution of S. ingrami nests in a woodlot located near to the headquarters of the Serra do Caraça Reserve, in state of Minas Gerais, where there is a high concentration of Syagrus romanzoffiana (Chamisso) Glassman palm tree, among other exotic tree species. The nest-building behaviour and the nest characteristics, such as height from the ground, total circumference, diameter of the entrance, and the position of the nest in the tree - in the crown, along the trunk or in a side branch, were described.
