Non-forest matrix crossing in the blueeyed black lemur Eulemur flavifrons (Gray, 1867)

摘要

The population of the Critically Endangered blue-eyed black lemur Eulemur flavifrons found in the Ankarafa Forest in northwestern Madagascar is well-characterised (Volampeno et al., 2011). The area consists of primary and secondary forest fragments and supports the largest remaining connected population of E. flavifrons (Schwitzer et al., 2005, Schwitzer et al., 2007). In the current study, lemur groups within two neighbouring, unconnected forest fragments (72 m apart at their closest point) were being studied: Forest Nora (a highly degraded fragment) and Forest Guy (a less degraded fragment).
