Informative microsatellites for genetic population studies of black-faced lion tamarins (Leontopithecus caissara)
Leontopithecus caissara is a critically endangered primate species from the Brazilian Atlantic Forest. Nineteen microsatellite loci, previously developed for congeneric species, were tested with 34 L. caissara individuals from Superagüi Island. Of the 19 loci, 17 (89.4%) produced robust alleles, nine (47.4%) of these proved to be polymorphic, with a total of 23 alleles and an average of 2.56 al...
متن کاملSources 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 کاملNatural and induced ovarian synchrony in golden lion tamarins (Leontopithecus rosalia).
Ovarian cycle synchrony was assessed in spontaneously cycling female golden lion tamarins by monitoring longitudinal (16 mo) urinary steroid metabolite (estrone conjugates; pregnanediol-3 alpha-glucuronide, PdG) excretion in four pairs (n = 8) of females isolated from males. The overall mean ovarian cycle duration was 18.5 +/- 0.3 days (n = 136 cycles; mean range, 15.7-21.0 days), and there was...
