Some institutions might wish to maintain reverse light cycles by using regular room lighting at night and low levels of red illumination during the day so that caregivers can observe them during their active period. The Duke University Primate Center has had the most comprehensive experience in the care of prosimians of any institution in the United States and is the largest captive prosimian colony in the world (Bennett and others 1995)

The Duke Primate Center has found weekly sanitation of shelter-box interiors and monthly sanitation of the cage furniture, nest boxes, and windows to be effective in maintaining sanitation and providing essential species odors. In contrast with true lemurs, Cheirogaleidae (mouse and dwarf lemurs)

Odors from dominant male mouse lemurs decrease testosterone concentrations and increase cortisol concentrations in isolated, unfamiliar males (Schilling and Perret 1987; Schilling and others 1984)

From page 63... ...
Gestation varies from as short as 2 months in mouse lemurs to 6 months or more in lorises, indrids, and tarsiers. True lemurs typically have brief, distinct breeding seasons.

From page 64... ...
Slender lorises will catch fish in water and stalk insects, birds, and small mammals. Gum-arabic feeders and such unusual food items as yogurt, eggs, and novel insects elicit the attention of all lorisines.

Newly arrived animals should receive fecal examinations weekly for at least 3 weeks. Stress produced by overcrowding sometimes leads to illness, especially liver and kidney problems.

From page 66... ...
Nutritional factors and the need to eat only live food affect the course of illnesses, because the animals stop feeding when weakened by illness. Pesticide residue can be a contributing factor to high infant mortality and loss of health.
