Resumo: | Exploratory human activities have resulted in small fragments inserted into a matrix which is inhospitable to small non-flying mammals. The effects of landscape changes alter the distribution patterns of species. Landscape fragmentation patterns for small mammals are controversial, especially considering small fragments and ecotonal regions. Based on these arguments, we investigated the diversity patterns of small mammals in small fragments in the ecotonal Cerrado/Atlantic Forest region. A total of 24 fragments (<40 ha) were studied using tomahawk, sherman and pitfall traps. We found low species richness (11 species, six marsupials and five rodents), which was not expected because it is an ecotonal region. It was verified that composition and community structure are simplified by the marked presence of generalist species and with the increase of species turnover. The small forest fragments present a microhabitat structure with lianas and streams as main environmental filters of groups with ecological similarities. Our findings suggest that these fragments must be managed in order to conserve the local biodiversity and maintain the needed characteristics to enable the occurrence of different ecological groups. |

Os efeitos das mudanças na paisagem alteram os padrões de distribuição das espécies. Os padrões de fragmentação da paisagem para pequenos mamíferos são controversos, especialmente considerando pequenos fragmentos e regiões ecotonais. Com base nesses argumentos, investigamos os padrões de diversidade de pequenos mamíferos em pequenos fragmentos na região ecotonal Cerrado / Mata Atlântica. Vinte e quatro fragmentos (<40 ha) foram estudados, usando armadilhas de grade, chapa e de queda. Encontramos baixa riqueza de espécies (11 espécies, seis marsupiais e cinco roedores), o que não era esperado por se tratar de uma região ecotonal. Verificamos que a composição e a estrutura da comunidade são simplificadas pela presença de espécies generalistas e com o aumento do turnover de espécies. Os pequenos fragmentos florestais apresentam uma estrutura de microhabitat com lianas e riachos como principais filtros ambientais de grupos com semelhanças ecológicas. Nossos resultados sugerem que esses fragmentos devem ser manejados para conservar a biodiversidade local e manter as características dentro dos fragmentos para possibilitar a ocorrência de diferentes grupos ecológicos.Museu de Ciências Naturais2022-01-28T17:28:43Z2022-01-28T17:28:43Z2021info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfMACHADO, F.
