...Julián Parada-López; Kim Valenta; Colin A. Chapman; Rafael Reyna-Hurtado Resting by primates is considered an understudied activity, relative to feeding or moving, despite its importance in physiological and time investment terms. Here we describe spider monkeys' ( Ateles geoffroyi ) travel from...

...H.G. Erkert; J. Gröber The activity pattern of Aotus lemurinus griseimembra can be predictably altered by varying the illuminance during the dark phase of a 12:12-hour light:dark rhythm. Intensities well below full-moon brightness (0.1–0.5 1x) severely inhibit activity. This modulation...

...C.W. Marsh Data on the activity pattern of a group of red colobus monkeys (Colobus badius rufomitratus) living along the Tana river, Kenya, were collected during monthly 5-day observation periods between October 1973 and December 1974. The two most important activities were feeding and resting...

...Gary A. Dawson Tamarin activity patterns and habitat utilization strategies in the Tropical Dry Forest of the Panama Canal Zone were monitored quantitatively using radio-location telemetry. The daily tamarin activity pattern differed from that of other Neotropical primates in that early morning...

...T.H. Clutton-Brock One troop of red colobus monkeys (Colobus badius tephrosceles) was observed in the Gombe National Park (Tanzania) and two other troops in the Kibale Forest Reserve (Uganda). The proportions of time spent in different activities by the animals were measured by counting, at quarter...

.... No indications, however, could be found to verify the theory of olfactory marking of traces. The activity of the animals is given as well in each experiment. 9 9 2008 © 1973 S.

...Alison M. Behie; Mary S.M. Pavelka The diet and activity of a population of Alouatta pigra were compared before and immediately after a major hurricane to begin to explore how the monkeys cope with severe habitat destruction. Focal animal data were collected from January to April (dry season...
