Abstract: | Both biotic and abiotic factors are important for maintaining the activity cycles of animals and may determine the most advantageous periods for eating, moving, and sleeping. Although the solar day–night cycle is among the most central of abiotic variables, a number of species are active both day and night. Three-toed sloth (genus Bradypus Linnaeus, 1758) populations across the Neotropics show this pattern, with activity occurring at various times within the 24 h cycle. In the current study, we used radio-tracking techniques to investigate the daily temporal patterning of brown-throated three-toed sloth (Bradypus variegatus Schinz, 1825) displacement in Amazonian flooded igapó forest and compared the results with populations studied in other habitats. We concluded that igapó sloths are cathemeral, and discussed that environmental temperature, nutritional needs and the presence of predators may be the main factors influencing their activity pattern. © 2021, Canadian Science Publishing.
