| pneumocystis carinii infections in zoo animals. | pneumocystis carinii was found to be present in the lungs of twenty-three zoo animals in the netherlands. the following species were represented: red kangaroo, common tree shrew, senegal-galago, demidoff's-galago, brown howler monkey, woolly monkey, long-haired spider monkey, white-eared marmoset, chimpanzee, three-toed sloth, palm squirrel, red panda, fennec fox, tree hyrax and large-toothed hyrax. | 1975 | 1079994 |

| patch size, functional isolation, visibility and matrix permeability influences neotropical primate occurrence within highly fragmented landscapes. | forest fragmentation and habitat loss are among the major current extinction causes. remaining fragments are mostly small, isolated and showing poor quality. being primarily arboreal, neotropical primates are generally sensitive to fragmentation effects. furthermore, primates are involved in complex ecological process. thus, landscape changes that negatively interfere with primate population dynamic affect the structure, composition, and ultimately the viability of the whole community. we evalua ... | 2015 | 25658108 |
| pelage variation and distribution of the black lion tamarin, leontopithecus chrysopygus. | the black lion tamarin, leontopithecus chrysopygus, is endemic to the atlantic forest of the interior of the state of são paulo in brazil. since the discovery of the species, authors have described variations in the pelage of l. chrysopygus, but the nature of this variation has remained unknown. we examined museum specimens and living animals to see if the pelage of l. chrysopygus varies individually, geographically or ontogenetically. we reviewed all known locality records of the species, and c ... | 2016 | 27802443 |
| mitochondrial coii gene sequences provide new insights into the phylogeny of marmoset species groups (callitrichidae, primates). | mitochondrial cytochrome oxidase ii (coii) gene sequences (549 base pairs) were used to investigate the taxonomic relationships among 12 marmoset (callithrix, cebuella and mico) taxa. a large number of substitutions were found in the third base codon positions, providing a strong phylogenetic signal in a gene coding a conserved protein. despite the significant affinity between the 2 amazonian genera cebuella and mico, found in recent molecular studies, the analysis presented here did not resolve ... | 2006 | 12566758 |
| parental care in the buffy-tufted-ear marmoset (callithrix aurita) in wild and captive groups. | studies on cooperative care of offspring in callitrichid primates are biased in favor of observations in captivity. in the wild, however, individuals have to deal with environmental pressures, which may influence their social behavior. we compared the individual effort attributed to parental care offered by members of a wild group (couple, plus a subadult helper) and two captive groups (a: couple, plus an subadult helper, b: couple, plus four adult helpers) of the buffy-tufted-ear marmoset, call ... | 2000 | 11241967 |

| spatial distribution of buffy-tufted-ear (callithrix aurita) and invasive marmosets (callithrix spp.) in a tropical rainforest reserve in southeastern brazil. | we investigated the spatial distribution of native and invasive marmoset species (callithrix), as well as their hybrids, in the serra dos órgãos national park (parnaso) and surrounding area in rio de janeiro state, brazil. to estimate occupancy and the detection probability, we surveyed 56 sites within the park and 52 sites outside its limits using vocal playbacks, as well as by interviewing local residents in the surrounding area. we estimated the occupancy and detection probability of callithr ... | 2017 | 29072335 |
| field notes and geographic distribution of callithrix aurita in eastern brazil. | callithrix aurita, an endangered marmoset endemic to eastern brazil, was observed from june to october 1982. preliminary observations suggest that behavioral and morphological differences exist which distinguish c. aurita from the common marmoset, c. jacchus. new data are provided on the geographic distribution of c. aurita, extending it northward within the known ranges of c. penicillata in the states of sao paulo and minas gerais and c. flaviceps in eastern minas gerais. | 1984 | 32106636 |
