ABSTRACT. 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, 10.5%) and Platyrrhinus lineatus (E. Geoffroy, 1810) (n = 10, 5.0%), and less represented were Lasiurus blossevilli (Lesson y Garnot, 1826) (n = 2, 1.0%), Eumops perotis (Schinz, 1821) (n = 2, 1.0%) e Vampyressa pusilla (Wagner, 1843) (n = 1, 0.5%). The richness of species found and the non-occurrence of phyllostomines in the reserve could be indicative of some level of forest disturbance.
One of the largest private reserves in the Atlantic Forest is the RPPN Estação Veracel, which along with the contiguous forested area of the Pau-Brasil Ecological Station, is an important part of the remaining Atlantic Forest of southern Bahia. We carried out an inventory of medium and large mammals in the Reserve during a 16-month camera trap survey, as well as conducted interviews with park rangers and searched for direct/indirect records, which revealed 33 species belonging to nine different Orders. Among the species recorded, six are categorized as threatened in the national list and four in the IUCN global list. The RPPN harbors species which are crucial to the ecosystem, many of which are in decline and threatened by high hunting pressure and reduction of habitat. The results confirm the relevance of the RPPN as a Key Biodiversity Area (KBA) for globally threatened species.
foram listadas como as principais ameaças para os mamíferos da Bahia. Trinta e três das 45 espécies ameaçadas ou 'Quase Ameaçadas' tiveram registros em 21 Unidades de Conservação (UC) de proteção integral, localizadas inteira ou parcialmente na Bahia, e 32 das 45 espécies são cobertas por Planos de Ação Nacional (PAN). A lista de mamíferos ameaçados de extinção na Bahia inclui percentual elevado de carnívoros, mamíferos aquáticos, primatas e ungulados, seguindo o padrão observado em listas vermelhas. O alto número de espécies 'Dados Insuficientes' e a concentração de esforços de pesquisa em regiões restritas do estado são alarmantes e sugerem ausência de planejamento e baixa aplicação de recursos para descrever a biodiversidade, resultando em um conhecimento limitado sobre as populações de mamíferos e suas distribuições geográficas. A Bahia ocupa uma posição de destaque para a conservação de alguns taxa cuja distribuição é total ou majoritariamente incluída no estado. Os biomas Caatinga, Cerrado e Marinho carecem de UC de proteção integral para representar sua mastofauna característica. A publicação da lista de mamíferos ameaçados de extinção, investimentos para a criação e proteção efetiva de UC existentes e outras ações previstas em PAN são instrumentos complementares que devem ser fomentados por instituições governamentais e não-governamentais no intuito de proteger a rica diversidade de mamíferos da Bahia.

ABSTRACT-FIRST EVALUATION OF MAMMALS CONSERVATION STATUS IN BAHIA, BRAZIL Endangered species lists identify real and potential taxa extinction risks at global and regional scales, supporting decision-making processes and public policy. The construction of the first list of threatened species in Bahia state started in 2013. This paper describes the evaluation of conservation status of mammals in Bahia and its main results. The list was built in three phases: (1) preparatory, (2) evaluation and (3) final (validation). One species was considered regionally extinct, 41 were included in categories of threat ('Critically Endangered', 'Endangered' or 'Vulnerable') and four were considered 'Near Threatened'. Moreover, 51 species were classified as 'Data Deficient'. Habitat loss and fragmentation, hunting and roadkill were listed as the main threats for mammals in Bahia state. Thirty three out of 45 threatened or 'Near Threatened' species were recorded in 21 strictly protected areas (PA), completely or partially located in Bahia, and 32 of the 45 species are included in National Action Plans (PAN). The list of threatened mammals of Bahia includes a high percentage of carnivores, aquatic mammals, primates and ungulates, following the pattern of red lists. The high number of 'Data Deficient' species and research effort concentration in relatively small regions along the state are alarming and suggest the absence of planning and insufficient resource destination for biodiversity description, resulting in a limited knowledge on mammal populatio...
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.
