The effect of roads on spider monkeys' home range and mobility in a heterogeneous regenerating forest [PDF]

, 2017
Arboreal fauna living in tropical ecosystems may be particularly affected by roads given their dependency on forest cover and the high vulnerability of such ecosystems to changes. Over a period of 4 yr, we followed subgroups of spider monkeys living in a
