Última Fecal androgen levels in common marmoset (Callithrix jacchus) males living in captive family groups BJMBR Castro,D.C.; Sousa,M.B.C.. In captive common marmoset groups, the reproductive inhibition observed in subordinate female seems to be a result of olfactory, visual and behavioral cues from the dominant female. However, few studies have examined the relationship among adult males living in the same social group. These studies have shown that reproductive failure among peer males seems to be based on hormonal and behavioral mechanisms. New insights on sexual strategies in primates have been shown using fecal steroids, but so far no information is available for common marmoset males. In the present study, we evaluated the influence of light-dark cycle, age and reproductive condition on the profile of fecal androgens in males living in the same family group. Feces were collected from six... Tipo: Info:eu-repo/semantics/article Palavras-chave: Common marmosets; Fecal androgens; Male sexual strategies; Circadian variation; Reproductive suppression.

The influence of abundance and distribution of fruits and gums resources in home range size and pattern of range use were investigated in Callithrix jacchus. From October 1996 to January 1998 two groups (QT and PB) that lived in a National Forest/IBAMA-RN in northeastern Brazil (6º5'S, 35º12'W), were observed once a week by instantaneous scan sampling. The frequency of quadrant's visit in the home range was recorded at five minute intervals. Trees used for feeding on fruits and/or gum by the study groups were marked with flagging tape and numbered. Samples of the food items were collected for identification. Data on the temporal variation in fruits abundance was based on the monthly phenological observations of the marked trees. Study groups showed small... Tipo: Info:eu-repo/semantics/article Palavras-chave: Common marmosets; Callitrhix jacchus; Home range; Range use.
