Ecological and Reproductive Correlates to Range Use in Red-Bellied Lemurs (Eulemur Rubriventer) and Rufous Lemurs (Eulemur Fulvus Rufus)

摘要: In this paper, I describe how ecological variables (diet, food availability, patch characteristics) and unrelated to availability such as reproduction territoriality, affect daily long-term ranging patterns in two primate species southeastern Madagascar: the rufous lemur (Eulemur fulvus rufus) red-bellied rubriventer). Daily path lengths (DPL), home range size, distance traveled between patches were compared contrasted species. Rufous lemurs ranged further on a basis than lemurs. Group ranges overlapped extensively did not defend borders. contrast, maintained exclusive use of their actively defended boundaries. Additionally, used more scattered these Ranging both correlated with but influenced by three seasonal variations diet: number visited, dietary diversity, feeding bouts. furthest when each was highest coincided same time period females lactating. A similar peak observed although they diet diverse. It is suggested that presence several reproductively active groups may influence choice consequently, patterns. lemur’s territoriality limit group movements constrain ranging.
