We classified tree use based on the tree species occupied
by an individual at the time of relocation and proportion
of species used was calculated for each sloth. Tree
species were identified with aid of Zuchowski (2007) and
following the nomenclature of Hammel et al. (2003). We
used a likelihood ratio test for goodness-of-fit to compare
tree use between the two sloth species. Using these data,
we also characterized the diversity of tree species used
by each individual and by all individuals pooled for each
species with Simpson’s index of diversity.
