Dispersal and philopatry influence gene flow and thus the spatio-genetic structure within and between populations. In callitrichids the flexible social and mating system corresponds with a variable migration pattern where both sexes might be philopatric or might disperse. We investigated the relationship between the spatio-genetic structure and migration patterns in a population of mustached tamarins, Saguinus mystax. Using the rapidly evolving hypervariable region I (HVI) of the mitochondrial control region and 11 microsatellite markers we detected a high variation (HVI: 16 haplotypes in 69 individuals; microsatellites: H(O) = 0.75, average: 7.45 alleles/locus), with mating partners usually not sharing the same haplotype, indicating that matings are generally between partners that are not closely related. Similar high variance of haplotype differences for male-male and female-female pairs, along with a slightly higher number of haplotype differences in males show that both sexes habitually migrate. Spatial analyses suggest that females usually migrate longer distances, corresponding to very limited breeding positions for females in a polyandrous social mating system.

Merkel cell polyomavirus (MCPyV) is the first polyomavirus to be associated with human cancer. Mechanistic studies attempting to fully elucidate MCPyV's oncogenic mechanisms have been hampered by the lack of animal models for MCPyV infection. In this study, we examined the ability of MCPyV-GFP pseudovirus (containing a green fluorescent protein [GFP] reporter construct), MCPyV recombinant virions, and several MCPyV chimeric viruses to infect dermal fibroblasts isolated from various model animals, including mouse (), rabbit (), rat (), chimpanzee (), rhesus macaque (), patas monkey (), common woolly monkey (), red-chested mustached tamarin (), and tree shrew ().

A wild-caught, research-naïve, adult male mustached tamarin (Saguinus mystax) experienced sudden onset of bilateral hindlimb paresis. Physical examination established the presence of paralysis and the lack of femoral pulses and deep pain in both legs. There were no signs of external trauma and, due to a poor prognosis, euthanasia was elected.

This study presents a molecular phylogeny of the Saguinus genus, based on the analysis of the DNA sequences of five nuclear loci with Alu insertions in 10 species. The concatenated alignment produced a polytomic arrangement with four main groups, although only two clades-the Amazonian (S. midas, S.

Spontaneous intracardiac thrombosis is rarely reported in animals, particularly nonhuman primates. The finding of 2 cases of intracardiac thrombi in mustached tamarins (Saguinus mystax) that died as a consequence of congestive heart failure prompted us to do a retrospective study to determine the frequency of this condition. Clinical records, necropsy reports, and tissues from 60 mustached tamarins that died or were euthanized between 1996 and 2009 were reviewed.

Many animals interrupt their moving with brief pauses, which appear to serve several different functions. We examined the function of such intermittent locomotion in wild living mustached tamarins (Saguinus mystax), small arboreal New World primates that form mixed-species groups with saddleback tamarins (Saguinus fuscicollis). We investigated how different environmental and social factors affect pausing during locomotion and used these data to infer the function of this behavior.
