We describe the behavioral repertoire of captive-born black tufted-eared marmosets (Callithrix penicillata) elicited by brief exposures to three potential mounted taxidermized predators (caracara hawk, Polyborus plancus; rattlesnake, Crotalus durissus; oncilla, Leopardus tigrina), and a stuffed toy. For each of the four stimuli, we submitted the subjects to(More)
Evolutionary theory and observation predict wider phenotypic variation in hybrids than parental species. Emergent phenotypic novelty in hybrids may in turn drive new adaptations or speciation by breaking parental phenotypic constraints. Primate hybridization is often documented through genetic evidence, but knowledge about the primate hybrid phenotype(More)
Transport in containers and an unfamiliar environment are potent stress-inducing factors in domestic cats. This stress can be evaluated using cortisol concentration in serum and through other related physiological responses, such as increased glycaemia and body temperature. There is evidence that in some animal species, while subjected to psychological(More)
Marmosets of the genus Callithrix are specialized in the consumption of tree exudates to obtain essential nutritional resource by boring holes into bark with teeth. However, marmoset preferences for particular tree species, location, type, and other suitable factors that aid in exudate acquisition need further research. In the current study, the intensity(More)
Hybridization is continually documented in primates, but effects of natural and anthropogenic hybridization on biodiversity are still unclear and differentiating between these contexts remains challenging in regards to primate evolution and conservation. Here, we examine hybridization effects on the mitochondrial DNA (mtDNA) control region of Callithrix(More)
Animal hybridization is well documented, but evolutionary outcomes and conservation priorities often differ for natural and anthropogenic hybrids. Among primates, an order with many endangered species, the two contexts can be hard to disentangle from one another, which carries important conservation implications. Callithrix marmosets give us a unique(More)
Zoonotic pathogens that cause leprosy (Mycobacterium leprae) and tuberculosis (Mycobacterium tuberculosis complex, MTBC) continue to impact modern human populations. Therefore, methods able to survey mycobacterial infection in potential animal hosts are necessary for proper evaluation of human exposure threats. Here we tested for mycobacterial-specific(More)
OBJECTIVE To compare the anesthetic and cardiovascular effects of dexmedetomidine/ketamine combinations in golden-headed lion tamarins. STUDY DESIGN Prospective blinded randomized study. ANIMALS Six healthy golden-headed lion tamarins, three males and three females were studied (mean body weight +/- SD = 0.498 +/- 0.054 kg). METHODS The animals were(More)
In the fourth paragraph of the Discussion section, reference #37 and #5 are switched. The paragraph should read as follows: "Although this study did not identify any IS6110 positives, previous studies have identified the presence of this locus in NewWorld primates [5]. However, the IS6110 mobile element has been found to be homologous in some related soil(More)
Bacteria of the genus Ehrlichia are Gram-negative and coccoid-shaped microorganisms that cause ehrlichiosis - a serious infectious disease that often leads to death. These bacteria present a strong zoonotic potential and primates may act as reservoir hosts. This study involved a molecular analysis to detect these microorganisms in blood samples collected(More)
