“…The association of the species to the fragment proximity clarified by the biplot graph and the model suggested the importance of this landscape component to the species occurrence, possibly also serving for shelter during the day. Cerdocyon thous has also been recorded in eucalyptus plantations by Lyra-Jorge et al (2008) and Dotta and Verdade (2007). Silviculture, as indicated by Rocha et al (2008), should be used by C. thous for foraging.…”

Crab-eating fox, Cerdocyon thous, is a habitat generalist species relatively common throughout its range inhabiting most environments owing to its low habitat requirements. Because no information is available for anthropogenic habitats, this study aimed to describe the species occurrence in a highly fragmented and heterogeneous landscape in southeastern Brazil. C. thous was surveyed in 95 study sites in four main land covers (native forest, eucalyptus forest, sugar cane and pasture) from April to September 2006. Presence records (ns28) and landscape variables (land cover, heterogeneity, stream and forest fragment distance, elevation and slope) were used for modeling in Maxent. The bootstrapping method was used for sampling 70% of the dataset for training and 30% for testing models. The species was equally distributed in all types of land cover, although it was more frequent in the sugar cane areas and more associated with forest fragments and heterogeneous habitats. The potential distribution model predicted forest patches and its surroundings as highly suitable for the species. It also predicted part of the sugar cane matrix as highly suitable, probably related to prey availability. Results suggested that the anthropogenic landscape studied encompasses many suitable habitats for species occurrence, resulting in the necessity to assess its potential role in vertebrate communities.

“…Dietz (1984) reported that although MW were highly sensitive to the physical presence of people, they were tolerant of agriculture and persisted where ranchers and farmers had earned a livelihood for generations. vynne (2010) has found MW in soya fields, Lyra-Jorge et al (2008) documented their presence in eucalyptus plantations, and Santos et al (2003) showed them to thrive on dairy farms cut from Atlantic forest. If sufficient resources are available, MW do not need intensive management.…”

“…Several studies suggest cautious optimism for maned wolf survival in farmland (Courtenay, 1994;Dietz, 1984;Lyra-Jorge et al, 2008;Santos et al, 2003;vynne, 2010). Outside Emas NP, Brazil, vynne (2010) found that MW can even survive in mechanized cropland where there is adequate land management, including at least 20% set aside on each farm as a wildlife refuge, and low-growing crops (soya) with sufficient rodent prey.…”

Emmons SerieS PublicationS of the SmithSonian inStitutionEmphasis upon publication as a means of "diffusing knowledge" was expressed by the first Secretary of the Smithsonian. In his formal plan for the Institution, Joseph Henry outlined a program that included the following statement: "It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge." This theme of basic research has been adhered to through the years by thousands of titles issued in series publications under the Smithsonian imprint, commencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series: In these series, the Institution publishes small papers and full-scale monographs that report on the research and collections of its various museums and bureaus. The Smithsonian Contributions Series are distributed via mailing lists to libraries, universities, and similar institutions throughout the world.Manuscripts submitted for series publication are received by the Smithsonian Institution Scholarly Press from authors with direct affiliation with the various Smithsonian museums or bureaus and are subject to peer review and review for compliance with manuscript preparation guidelines. General requirements for manuscript preparation are on the inside back cover of printed volumes.

Most data were collected by GPS-collar technology, which yielded over 37,000 locations in 27 collar deployments on 10 individuals. The eight chapters introduce the study area and methods (1) and describe daily and seasonal activity (2); movements and ranges (3); diet and energetics (4); social interactions and reproduction (5); disease exposure, morbidity and mortality (6); maned wolf conservation (7); and finally, we synthesize the results in an overview of maned wolf behavioral ecology, with hypotheses about the unique form and function of this atypical canid (8). Activity was temperature related and sharply nocturnal in the dry season but partly diurnal in the rainy season. Adult home ranges were 40-123 km 2 , with strong seasonal variations in land use. Maned wolves averaged 14 km/night travel in dry months and 7 km/night during wet months. Breeding pairs shared territories with contiguous borders, which did not overlap with neighboring pairs. Young females twice stayed until adulthood on natal territories, as presumed helpers, and a...

“…A failure in the detection of the two feline species mentioned above could be due to two non-excludent reasons, (1) their naturally low population densities (Lyra- Jorge et al 2008, Almeida et al 2013, and (2) the high frequency of Puma concolor and Leopardus pardalis in several trails, whose presence has been negatively related to the occurrence of these species , Oliveira 2011, Oliveira-Santos et al 2012. In addition, for L. wiedii, trail characteristics -which were more open, wide and managed than the preferred by the species --could have contributed to this result (Goulart et al 2009).…”

Medium and large-sized mammals of the Reserva Ecológica de Guapiaçú, Cachoeiras de Macacu, RJ

Medium and large-sized terrestrial mammals develop important functions in ecosystems maintenance. However, this group is the most vulnerable to local extinctions, through habitat loss or hunting. This study inventoried the community of medium and large mammals in the Reserva Ecológica de Guapiaçú (REGUA), Cachoeiras de Macacu, RJ, providing data on species composition, richness and abundance. Species were registered through the use of camera traps, sign survey and visual encounters on pre-existing trails and roads. The study was conducted from January to October 2012, with each month considered as a sample unit. An effort of 1568 cameras-day and 120 km traveled, resulted on 302 records of 22 species of medium and large-sized mammals, belonging to eight orders. This value corresponds to more than three-quarters of the richness described from this group in the Atlantic Forest of Rio de Janeiro state. Five species are under some level of regional, national or global threat. Three game species, Pecari tajacu, Cuniculus paca and Dasyprocta leporina were abundant in the area. The observed richness was comparable to that found in other studies conducted in rain forests. Thus, for its high number of species, including those under some degree of threat, we conclude that REGUA is an important area to mammal conservation, especially in the Atlantic Forest of Rio de Janeiro state.
