Lemur

Non-invasive blood sampling from primates using laboratory-bred blood-sucking bugs (Dipetalogaster maximus; Reduviidae, Heteroptera)

Primates are easily stressed by the conventional veterinary blood sampling routine and consequently, measured blood parameters may be biased. In this study, we tested blood-sucking bugs (Dipetalogaster maximus) on one lemur and two ape species (Microcebus murinus, Pongo abelii, Pan...

Socially-mediated learning in groups of primates: models and methods

An ethological understanding of a behavioral phenomenon incorporates four levels of explanation: development, mechanism, function, and evolution. The phenomenon of socially-mediated learning has garnered a great deal of attention from ethologists, prominently including primatologists. Gregarious primates often exhibit specific behaviors...

Does cortisol provide an objective measure of subjective feelings? Maybe not

Although our results do not negate the use of cortisol as a welfare indicator in Lemur catta, they do highlight the myriad of behavioural and environmental factors in addition to stress that modify cortisol excretion in this species in captivity.

Captive lemur response to two types of natural enrichment

Enrichment has been known to increase the well being and species typical behavior of captive animals. While much research has been done on the effectiveness of enrichment or captive monkeys and apes, research on enrichment of captive lemurs is not...

Components of an animal training program at a large institution

The application of positive reinforcement training (PRT) has increased in zoological, laboratory, and research settings in recent years, however there is little literature pertaining to the development and implementation of such programs. Over the past year, Yerkes National Primate Research...

Ice-timed feeders to promote foraging

For many animals in nature, foraging is simply a matter of traveling and discovering available food. It provides both physical exercise and mental stimulation, often consuming much of an animal's time. Replicating this in a small, enclosed space is one...

A rational approach to enriched nutrition for nonhuman primates

Obesity is a concern with nonhuman primates (NHPs) housed in captivity for extended periods of time, mostly due to overfeeding and lack of exercise. This is often compounded by environmental enrichment programs that include different types of food. That is...

Does simple feeding enrichment raise activity levels of captive ring-tailed lemurs (Lemur catta)

Feeding enrichment is a commonly proposed way to promote natural behavior, greater activity levels and improved health in captive primates, but in many cases the methods have not been formally tested, especially for particular groups such as lemurs. We investigated...
