Effect Of Group Size On The Activity Budget Of Two Captive Chimpanzees (Pan Troglodytes), Kaeley Sullins

All Master's Theses

Captive facilities housing chimpanzees are required to provide adequate care and provisions such as dietary, social, and environmental enrichment to promote the psychological well-being of the apes in their care. Chimpanzees are social creatures and changes in groups as well as relocation to a facility with new social partners, can impact each individual chimpanzee’s welfare. By tracking each chimpanzee’s activity budgets, managers can assess welfare and make improvements or adjustments if necessary. I looked at the activity budgets of two captive chimpanzees after the death of a group member and the two chimpanzees’ subsequent relocation to a novel, more socially …

Effects Of Psycho-Physiological Stress On Captive Dolphins, Nick Carter

Conservation Collection

Morgane (1978) has stated that:

Man sees all other creatures through the narrow focus of his own knowledge and sees the whole image in distortion. We patronize animals for their incompleteness and dependence and for their fate in having taken form so far below ourselves ... a great mistake, for animals should not and cannot, be measured by man. Many are gifted with many extensions of senses we have lost or never attained .... They live by voices we may never hear. Some may not be our accepted brethren, but also they are not our underlings.

If this "narrow focus …

Deep Woodchip Litter: Hygiene, Feeding, And Behavioral Enhancement In Eight Primate Species, Arnold S. Chamove, James R. Anderson, Susan C. Morgan-Jones, Susan P. Jones

Ethology Collection

Sixty-seven animals from eight primate species were used to assess improved husbandry techniques. The presence of woodchips as a direct-contact litter decreased inactivity and fighting, and increased time spent on the ground. Placing food in the deep litter led to further behavioral improvement. The use of frozen foods improved food distribution and reduced fighting in most situations, especially when it was buried in the litter. With time, the litter became increasingly inhibitory to bacteria. The results suggest that inexpensive ways of increasing environmental complexity are effective in improving housing for primates.
