          Abstract

          Abstract: Habitat fragmentation is one of the principal causes of the decline of species worldwide, and the Brazilian Atlantic Forest and Cerrado savanna biomes are among the most severely affected by this process. While highly fragmented, remnants of Atlantic Forest can still be found within the Cerrado domain of southern Goiás, where previous studies have revealed high levels of biodiversity. To inventory the mammalian species that occur in the region, two fragments of semideciduous Atlantic Forest were sampled between 2011 and 2016, using line transect surveys and camera trapping. A total of 1016 records were obtained of 30 mammal species, of which eleven are under some threat of extinction. The species richness recorded on this study was similar to or higher than the values reported from other areas of Goiás, which reinforces the importance of the maintenance of these remnants, located in private properties, for the conservation of the region's mammals.

          Resumo: A fragmentação de hábitat é uma das principais causas do declínio das espécies e tanto a Mata Atlântica quanto o Cerrado são considerados um dos biomas mais afetados do mundo. As regiões sul e sudoeste de Goiás são intensamente fragmentadas, mas ainda abrigam alguns dos últimos remanescentes relictuais de Mata Atlântica dentro do domínio do Cerrado e estudos prévios revelaram uma alta biodiversidade. Com o objetivo de elaborar a lista de espécies de mamíferos que ocorrem para a região, dois fragmentos de florestas semideciduais da Mata Atlântica foram amostrados entre 2011 a 2016, através de transecções lineares e armadilhas fotográficas. Foram obtidos um total de 1.016 registros de 30 espécies de mamíferos, das quais onze estão ameaçadas de extinção. A alta riqueza registrada foi similar ou maior ao de outras áreas no Estado e reforça a importância da manutenção desses remanescentes localizados em propriedades particulares para a conservação das espécies.

              Estimating species richness using the jackknife procedure.

              An exact expression is given for the jackknife estimate of the number of species in a community and for the variance of this number when quadrat sampling procedures are used. The jackknife estimate is a function of the number of species that occur in one and only one quadrat. The variance of the number of species can be constructed, as can approximate two-sided confidence intervals. The behavior of the jackknife estimate, as affected by quadrat size, sample size and sampling area, is investigated by simulation.
