Sources of variability in numbers of live births in wild golden lion tamarins (Leontopithecus rosalia).
We examined the effects of several variables on the number of live births in multiparous females in a wild population of golden lion tamarins (Leontopithecus rosalia). Independent variables included the number of infants born to a female the previous breeding season, the number of infants weaned the previous breeding season, the female's age and body mass, the number of adult males and helpers ...
متن کاملLocomotion of Free-Ranging Golden Lion Tamarins (Leontopithecus rosalia) at the National Zoological Park
Locomotor behavior and substrate use of cage-reared golden lion tamarins (Leontopithecus rosalia), newly released and free-ranging on the grounds of the National Zoological Park, were studied to determine if locomotion changed following exposure to naturalistic conditions. The animals employed a predominantly quadrupedal locomotor profile, incorporating leaping and vertical climbing to a lesser...
متن کاملDiagnosis and repair of familial diaphragmatic defects in golden lion tamarins.
Diaphragmatic defects were identified in 11 of 130 golden lion tamarins. Seven of the cases were found at necropsy (52 tamarins) and 4 were diagnosed by radiography (78 tamarins). When screening radiography revealed a thoracic mass, a barium series was indicated and either demonstrated loops of bowel within the thorax or suggested liver displacement by the cranial location of the intestine. In ...

متن کاملEnergy intake, energy expenditure, and reproductive costs of female wild golden lion tamarins (Leontopithecus rosalia).
Callitrichid females are often described as energetically constrained. We examined the energy budgets of 10 female wild golden lion tamarins (GLTs, Leontopithecus rosalia) in an effort to understand how energy intake and expenditure might influence physical condition and therefore reproductive performance. We used focal animal sampling to record behavioral data and conducted energy analyses of ...
