Zusammenfassung: | [Introduction]: Wildlife refuges are crucial to improve connectivity in the context of biological corridors, as they conserve forest patches and consequently neotropical mammal populations. However, in order to devise conservation and management strategies, it is a priority to carry out field studies that validate these efforts and measure their effectiveness over time. [Objective]: To generate baseline information on the population status of medium and large terrestrial mammals and their activity patterns, to help the management and protection of the Lapa Verde Wildlife Refuge. [Methods]: we analyzed the camera-trapping methodology by placing 13 camera traps per sampling block, divided in two blocks (1 855 ha) during January - February 2015 and December 2015 - January 2016. [Results]: The sampling effort was 1 584 nights, capturing 18 species with the presence of large and medium predators such as Panthera onca, Canis latrans, Leopardus pardalis and Leopardus wiedii, as well as species of prey such as Silvilagus sp., Dasypus novemcinctus, Dasyprocta punctata and Cuniculus paca. The species with the highest RAI was D. punctate. The richness was similar between blocks. However, the patterns of circadian activity differed between some species (L. pardalis and D. punctata). [Conclusions]: Species such as jaguars and tapirs, that require large areas of land to settle, use these conservation blocks which indicates the importance of the conservation of these blocks.
[Introdução]: Refúgios de vida silvestre são fundamentais para melhorar a conectividade no contexto de corredores biológicos, uma vez que conservam fragmentos florestais e consequentemente populações de mamíferos neotropicais, no entanto, para se traçar estratégias de conservação e manejo, é prioritário realizar estudos que validar esses esforços e medir sua eficácia ao longo do tempo. [Objetivo]: Gerar informações básicas sobre a situação populacional de mamíferos terrestres de médio e grande porte e seus padrões de atividade, que contribuam para o manejo adequado e proteção deste grupo no Refúgio de Vida Silvestre da Lapa Verde. [Metodologia]: Foi utilizada a metodologia de foto-armadilhagem, colocando 13 armadilhas fotográficas por bloco de amostragem, em dois blocos (1 855 ha) durante janeiro - fevereiro de 2015 e entre dezembro de 2015 - janeiro de 2016. [Resultados]: O esforço da amostragem foi de 1 584 noites, registrando 18 espécies com a presença de predadores grandes e médios como Panthera |
