“…The relative abundance of these species in this region is considerable, especially due to the existence of residents. The activity patterns of the species follow the description by Negrões (2011), and observerd by Botelho (2013) in RESEX Alto Tarauacá, Acre, Brazil. The high number of diurnal records of red deer, for example, is important.…”

The implementation of private areas focused on conservation of species and habitats, combined with REDD+ policies, has become an important ally for biodiversity conservation, expanding the conservation areas of the most varied habitats, covering key groups such as large mammals, which are extremely important for the maintenance of ecosystem services. In the upper region of the Purus River in Acre, Brazil, an inventory was carried out using camera-traps, of medium and large mammals community in a private REDD+ area, known as the Purus Project. A total of 19 species of mammals were recorded with an effort of 1859 trap-nigths, including rare, endangered and key species. It is estimated that the richness for the area is of 22 species. Endangered and rare species such as the tapir (Tapirus terrestris) and the short-eared dog (Atelocynus microtis) presented high rates of relative abundance compared to other Conservation Units (UCs). The richness of medium to large-sized mammals recorded in the Purus Project underscores the importance of REDD+ in private areas for the conservation of this group, given the challenges for inclusion and creation of new protected areas. REDD+ projects in privates' areas become an important component for conservation of species and the connection between public conservation units favoring the spread of species and populations between areas, and consequently the gene flow.

Abundância e composição de mamíferos de médio e grande porte em uma área privada de projeto REDD+ no Acre, BrasilResumo: A implementação de áreas privadas voltadas para conservação de espécies e habitats, aliadas a políticas de REDD+, tem se tornado importante aliada para conservação da biodiversidade, ampliando as regiões de conservação dos mais variados habitats, abrangendo grupos chaves como grandes mamíferos, extremamente importantes para manutenção dos serviços ecossistêmicos. Na região do alto rio Purus, Acre, Brasil, foi realizado um inventário utilizando armadilhas fotográficas, da comunidade de mamíferos de médio e grande porte de uma área privada de REDD+, o Projeto Purus. Foram registradas 19 espécies de mamíferos, com um esforço de 1.859 armadilhas-noite, incluindo chaves, raras e ameaçadas de extinção. Estima-se que a riqueza esperada para a área seja de 22 espécies. Espécies ameaçadas e raras como a Anta (Tapirus terrestris) e o Cachorro-do-mato (Atelocynus microtis) apresentaram taxas de abundância relativa elevadas, comparadas com outras UCs. A riqueza de médios e grandes mamíferos registrados na região do Projeto Purus ressalta a importância de REDD+ em áreas privadas para conservação deste grupo, dado os desafios para inclusão e criação de novas áreas protegidas públicas. Assim projetos de REDD+ em áreas privadas se tornam um importante componente para conservação de espécies e para a conexão entre Unidades de Conservação públicas favorecendo a dispersão de espécies e populações entre áreas, e consequentemente o flu...

“…For instance, its relative abundance in PA Maracá is ~70% of the overall abundance of the area, and is almost the total relative abundance of the second most abundant area, PA Uatumã. As expected, the latter does not have such a high Tayassu pecari abundance as most areas of the Guyana shield (Munari et al 2011, Negrões et al 2011, Botelho et al 2012, Santos and Oliveira 2012.…”

Mammal communities in the vicinity of human settlements are often subject to subsistence hunting and retaliatory killings. We used fourteen digital camera traps equipped with infrared triggers to sample the medium-sized and large mammal communities for ca. 34 (±1.64) days per site. Diversity was measured as both Shannon entropy and Fager´s number of moves (NMS), and dominance was quantified using the Berger-Parker index. We used Kruskall-Wallis tests to investigate if there were statistically significant differences in richness, diversity and dominance among the sites. At an overall sampling effort of 1,946 trap days we recorded 216 independent observations of a total of 20 species belonging to 17 genera and 15 families. Richness and diversity appeared to be determined by forest structure, since, independent of the level of human impact, the richest areas were those closest to the ombrophilous forests of southern Guyana shield, closest to central Amazonia, whereas the poorest were at those sites closest to the vegetation mosaics of central Guyana shield. The disappearance of Tayassu pecari from the impacted areas as well as higher relative abundances in the protected areas, albeit not significant, foresees a possible bleak future for the mammalian assemblages in the near future.

“…The creation of private reserves has been an important strategy for biodiversity conservation in Brazil (e.g. Schiavetti et al 2010, Negrõ es et al 2011. At REGUA, as in other private reserves, the surveillance is done generally by locals, mostly former hunters, who know the region well and are able to keep gatherers and hunters away.…”

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.
