AI Article Synopsis
- Leontopithecus caissara is a critically endangered primate from the Brazilian Atlantic Forest, and a study was conducted using 34 individuals from Superagüi Island.
- Of the 19 microsatellite loci tested, 17 produced strong genetic markers, with 9 of those being polymorphic, resulting in a total of 23 alleles and diverse genetic variation.
- The study revealed the potential benefits and limitations of using these microsatellite loci for genetic analysis of L. caissara, and suggested their possible application for other related species.
Article Abstract
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 alleles per locus. Expected and observed heterozygosity averaged 0.483 and 0.561, respectively. The exclusion power for identifying the first parent of an arbitrary offspring was 0.315 over all loci. The results thus indicate both the usefulness and limitations of these nine microsatellite loci in the genetic analysis of L. caissara, as well as their potentiality for genetic investigation in other congeneric species.

Primates play an important role in ecosystem functioning and offer critical insights into human evolution, biology, behavior, and emerging infectious diseases. There are 26 primate species in the Atlantic Forests of South America, 19 of them endemic. We compiled a dataset of 5,472 georeferenced locations of 26 native and 1 introduced primate species, as hybrids in the genera Callithrix and Alouatta.

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 report on (i) new group formation, (ii) sex differences in dispersal and (iii) dispersal distance over 6 years for 3 social groups of the black-faced lion tamarin (Leontopithecus caissara) in the vicinity of Ariri, São Paulo state, Brazil. The groups were: Bina (monitored for 74 months), BM5 (52 months) and Teca (13 months). Each group was censused once a week and monitored for 3 days each month.

Understanding how biodiversity will respond to climate change is a major challenge in conservation science. Climatic changes are likely to impose serious threats to many organisms, especially those with narrow distribution ranges, small populations and low dispersal capacity.

Background: This study evaluated the presence of rotavirus groups A, B, and C (RV-A, RV-B, and RV-C), sapovirus (SaV), and norovirus (NoV) in asymptomatic non-human primates (NHP).
Methods: Fecal samples were collected from 19 recently captured (Red-howler, Alouatta guariba clamitans, n = 18; Howler, Alouatta caraya, n = 1) and 43 free-ranging NHP (Marmosets, Callithrix spp., Callithrix penicillata, n = 30; Black-faced lion tamarin, Leontopithecus caissara, n = 12, Red-howler, Alouatta guariba clamitans, n = 1) that were maintained in southern Brazil without manifestation of diarrhea.
