Activity pattern, budget and diurnal rhythmicity of the brown-throated three-toed sloth (Bradypus variegatus) in northeastern Brazil
Previous studies exploring the rhythmic activity of sloths of the Bradypus genus in undisturbed forests revealed cathemeral patterns of activity. In the current study we wished to examine sloth behavior in a highly disturbed secondary forest habitat. We evaluated activity pattern, time budget and rh...

Previous studies exploring the rhythmic activity of sloths of the Bradypus genus in undisturbed forests revealed cathemeral patterns of activity. In the current study we wished to examine sloth behavior in a highly disturbed secondary forest habitat. We evaluated activity pattern, time budget and rhythmic activities of brown-throated three-toed sloths (B. variegatus) living in the border of a highly disturbed forest fragment in northeastern Brazil. Three adults (2 females and 1 male) and 2 infants were studied over 29 days.
