Resumo
The maned wolf (Chrysocyon brachyurus, Illiger, 1815, Canidae) is a threatened
species that inhabits the cerrados of Brazil, Argentina, Peru, Bolivia, Paraguay,
and Uruguay. Captive maned wolves could be potentially used in reintroduction
programs for species conservation; however, it is necessary that their behavior and
cognitive abilities are conserved. Environmental enrichment is a tool used
to stimulate captive animals and maintain a natural behavioral repertoire.
To compare the variation of captive maned wolves’ behavioral responses to
environmental enrichment, we studied three maned wolves held by Belo Horizonte
Zoo, Brazil. Foraging, interspecific, and intraspecific stimuli were offered to the
animals and their responses were compared with a baseline and postenrichment
treatments. The test was used to help in choosing which one of the three
individuals would participate in a reintroduction project. The results showed that stimuli type did influence the animal’s responses, and that individually wolves
responded differently to foraging, interspecific, and intraspecific enrichment items
(Po0.05 for some behaviors in each enrichment category). The individual’s
personality seemed to influence their behavioral responses, with animals showing
bold and shy responses, and this trait should be considered during decision.
