Social organization of free-ranging ruffed lemurs,Varecia variegata variegata: mother-adult daughter relationship

Social Organization of Free-Ranging Ruffed

The relationship between a mother and an adult daughter is examined in a group of free-ranging ruffed lemurs (Vurecia uuriegutu) at the Duke University Primate Center (DUPC). Although the two females were aEliative during the birth season, interactions during the mating season were predominantly agonistic. The maturing daughter was dominant to the mother, as has been observed in many caged soci...

Functional analysis of aggression in a black-and-white ruffed lemur (Varecia variegata variegata).

A functional analysis was conducted to assess the antecedent and reinforcing conditions underlying aggressive behavior in a female lemur in captivity. Results showed that her aggression was primarily the result of human attention. A replacement behavior-training program was introduced, and the lemur's aggression was successfully eliminated. These results demonstrate the utility of using functio...

Hepatoprotective properties of Bauhinia variegata bark extract.

Bauhinia variegata (Leguminosae) commonly known as Kachnar, is widely used in Ayurveda as tonic to the liver. The present work was carried out to assess the potential of Bauhinia variegata bark as hepatoprotective agent. The hepatoprotective activity was investigated in carbon tetrachloride (CCl(4)) intoxicated Sprague-Dawley rats. Bauhinia variegata alcoholic Stem Bark Extract (SBE) at differe...

Naturally Occurring Ehrlichia chaffeensis Infection in Two Prosimian Primate Species: Ring-tailed Lemurs (Lemur catta) and Ruffed Lemurs (Varecia variegata)

A naturally occurring infection of Ehrlichia chaffeensis in lemurs is described. DNA of Ehrlichia chaffeensis was identified by polymerase chain reaction in peripheral blood from six of eight clinically ill lemurs. Organisms were cultured from the blood of one lemur exhibiting clinical and hematologic abnormalities similar to those of humans infected with E. chaffeensis.
