ABSTRACT. Composition and characterization of the mammal fauna of Emas National Park, Goilis, Brasil. Emas National Park is a very important Conservation Unit in the Cerrado Biome. Nevertheless the fauna of this region is still poorly known. In this study, a revised list of the mammal fauna of the Emas National Park with comments about the composition and the number of species surveyed is presented. Eighty six species of mammals were recorded in the Park and neighboring area, including several rare and threatened species, like the bush dog (Speothos venaticus (Lund , 1842)), Marsh deer (Blastocerus dichotonws (Illiger, 1815)) and others. The giant rat (Kunsia tomentosus (Lichtenstein, 1830)) was recorded for the first time in a conservation unit. On the other hand, species usually very common in the Cerrado biome, don't occur in Emas National Park: the brazi lian rabbit (Sylvilagus brasiliensis (Linnaeus, 1758)), marmosets (Callirhrix spp.), and the punare (Thrichomys apereoides (Lund, 184 I)). KEY WORDS . Cerrado, conservation, mammalian survey o Cerrado, segundo maior bioma sul-americano, abrange mais de dois milhoes de quil6metros quadrados e possui uma rica fauna de mamfferos composta por 190 especies (MARINHO-FILHO et aI. , no prelo). Ao longo dos ultimos 50 an os o Cerrado vern sendo gradativamente substitufdo por areas de pastagem e lavoura (NEPSTAD et al. 1997) e hoje 35% da area total do Bioma ja esta ocupado por atividades agrfcolas (MACEDO 1995). Atualmente men os de 1 % do Cerrado esta preservado em unidades de conservayao federais de uso indireto (PADUA 1996; 1) Associaifao Pra-Carnivoros. SON 412 K 305, Distrito Federal.
The distribution, natural history, and morphology of Kerodon acrobata were updated based on nine new collected specimens totalling 14 known specimens. Two new localities were added to the distribution range of this species. Data on habitat use indicated that the presence of this rodent is associated to the cerrado sensu stricto and seasonally dry tropical forest patches in the northeastern Cerrado domain. Analyses of these specimens increased the range of body size and craniodental measurements for K. acrobata. We also describe, for the first time, phallic morphology of K. acrobata which exhibits a subcylindral glans penis and a simple baculum. High hunting activity and continuous loss of its natural habitat are factors that can be negatively affecting its populations. Habitat replacement poses a likely risk the present diversity at seasonally dry tropical forest enclaves of the northeastern Cerrado domain.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
