Modifying spider monkey behavior with the use of environmental variables

The introduction of the leaves and the food pod [food loaded PVC pipe with finger holes suspended from tree] reduced the amount of off-display time by nearly half. During baseline observations, the monkeys spent 7.3% of the time feeding, but...

Mealtime activity for lemurs

An enrichment feeding technique for lemurs that is inexpensive and requires minimal preparation time, yet seems to give the lemurs a chance to exhibit natural feeding behaviors. I used the hard outer shell of half a coconut and filled it...

Effects of repeated restraint stress at 30-minute intervals during 24-hours on serum testosterone, LH and glucocorticoids levels in male Japanese monkeys (Macaca fuscata)

30-min intervals sampling [using compulsory restraint ] serum testosterone levels decreased and glucocorticoid levels increased, respectively, immediately after the start of blood sampling. LH levels were not affected.

Incorporating environmental enrichment into behavioral research in captive chimpanzees, Pan troglodytes

The proximate goal of this project was to create an enrichment protocol designed to enhance the physical space and foraging opportunities ... by introducing a variety of novel food and non-food objects into the home cage.

Diving and underwater swimming as enrichment activities for captive rhesus macaques (Macaca mulatta)

In order to assess the environmental enrichment value of a small swimming pool for captive juvenile rhesus macaques (Macaca. mulatta), observations of social and individual behaviours were made during baseline and experimental (pool) conditions. When the pool was available there...
