Life in a fragment: Evolution of foraging strategies of translocated collared brown lemurs, Eulemur collaris, over an 18-year period

摘要: While the drivers of primate persistence in forest fragments have been often considered at population level, strategies to persist these habitats little investigated individual or group level. Considering rapid variation fragment characteristics over time, longitudinal data on primates living fragmented are necessary understand key elements for their persistence. Since translocated animals cope with unfamiliar areas and face unknown fluctuations food abundance, they offer opportunity study factors contributing successful migration between fragments. Here, we illustrated evolution foraging collared brown lemurs (Eulemur collaris) an 18-year period Mandena Conservation Zone, south-east Madagascar. Our aim was explore ability frugivorous adjust recently colonized forests. Although remained mainly throughout period, years identified a reduction consumption leaves exotic/pioneer plant species. These adjustments were expected degraded area, but hypothesize that may also reflect initial need environment after translocation. fragmentation is associated loss large trees native vegetation, suggest availability exotic and/or pioneer species can provide easy-to-access, nonseasonal resource be factor during stage recolonization.
