Survey of stereotypic behavior in prosimians

According to the responses [from AZA-accredited institutions], 13.2% of the prosimians surveyed exhibited some form of stereotypic behavior. Pacing was the most common behavior. .. It is interesting to note that 58.3% of the institutions that housed individuals that engaged...

Effects of three food enrichment items on the behavior of black lemurs (Eulemur macaco macaco) and ringtail lemurs (Lemur catta) at the Henson Robinson Zoo, Springfield, Illinois.

The lemurs' behavior appeared [sic] to be most affected by the food enrichment item that required the most manipulation.

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...
