The Golden Lion Marmoset

THE BEHAVIOR AND CONSERVATION OF THE GOLDEN LION TAMARIN, Leontopithecus r. rosalia

The three forms of Leontopithecus are among the most $ endangered of Brazil's primate fauna. For the past 20 years Coimbra-Filho and colleagues have been working to ensure the survival of lion tamarins in their original habitat in the unique southeastern coastal forests of Brazil. Simultaneously, both Brazilian and international efforts have focused on the development of management techniques t...

Locomotion 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...

Patterns of urinary oestrogen excretion in female golden lion tamarins (Leontopithecus rosalia).

Daily urine samples were collected from 5 female golden lion tamarins (Leontopithecus rosalia) over a period of 3 or more months, and urinary oestrogen concentrations were determined by radioimmunoassay. Four females exhibited regular patterns of oestrogen excretion, with a peak-to-peak periodicity of 19.6 +/- 1.4 days. Levels of oestrogen excretion tended to vary between, but not within, indiv...

Foraging ecology and use of space in wild golden lion tamarins (Leontopithecus rosalia).

In this paper we describe the use of space and feeding ecology of seven groups of golden lion tamarins observed for a total of 2,164 hr in Poço das Antas Reserve, Rio de Janeiro, Brazil. Relative to habitat availability in the home ranges of these groups, lion tamarins spent more time than expected in relatively undisturbed swamp forests and less time than expected in more degraded hillside and...
