  • The study of activity rhythms, their potential zeitgebers and masking factors among free-ranging primates has received relatively little attention in the past. [...] Key Method During 1 year, I collected activity data from five groups followed continuously from dawn to dusk, dusk to dawn or uninterruptedly during 24 or 36 h for approximately 1,500 h. I kept hourly and daily records of temperature and light conditions, and I gathered monthly information on the density, distribution and abundance of food…Expand Abstract
