Relative tooth size at birth in primates: Life history correlates
OBJECTIVES: Dental eruption schedules have been closely linked to life history variables. Here we examine a sample of 50 perinatal primates (28 species) to determine whether life history traits correlate with relative tooth size at birth. MATERIALS AND METHODS: ) of the upper jaw were measured and residuals from cranial length were calculated with least squares regressions to obtain relative dental volumes (RDVs). RESULTS: Relative dental volumes…
MtDNA diversity in azara's owl monkeys ( Aotus azarai azarai ) of the Argentinean Chaco
Owl monkeys ( Aotus spp .) inhabit much of South America yet represent an enigmatic evolutionary branch among primates. While morphological, cytogenetic, and immunological evidence suggest that owl monkey populations have undergone isolation and diversification since their emergence in the New World, problems with adjacent species ranges, and sample provenance have complicated efforts to characterize genetic variation within the genus. As a resul…
Mated pairs of owl monkeys ( Aotus nancymaae ) exhibit sex differences in response to unfamiliar male and female conspecifics
In socially monogamous species, mate‐guarding could be a reproductive strategy that benefits both males and females, especially when males contribute to parental care. By actively guarding mates, males may reduce their chances of being cuckolded, whereas females that mate‐guard may reduce the likelihood that their mates will desert them or acquire additional mates, and hence limit or reduce paternal care of offspring. Owl monkeys ( Aotus spp.) ar…
Sex, age, and family differences in the chemical composition of owl monkey ( Aotus nancymaae ) subcaudal scent secretions
Numerous behavioral studies have shown that animals use olfactory cues as inbreeding avoidance or kin avoidance mechanisms, implying that scent is unique to families. However, few studies have analyzed the chemical profile of a scent and ascertained the messages that are conveyed in scent secretions. Owl monkeys ( Aotus nancymaae ) are socially monogamous primates that utilize scent when interacting with foreign conspecifics. This suggests there …
A Participatory Action Research Pilot Study of Urban Health Disparities Using Rapid Assessment Response and Evaluation
Healthy People 2010 made it a priority to eliminate health disparities. We used a rapid assessment response and evaluation (RARE) to launch a program of participatory action research focused on health disparities in an urban, disadvantaged Black community serviced by a major south Florida health center. We formed partnerships with community members, identified local health disparities, and guided interventions targeting health disparities. We des…
Mutational changes in S‐cone opsin genes common to both nocturnal and cathemeral Aotus monkeys
Aotus is a platyrrhine primate that has been classically considered to be nocturnal. Earlier research revealed that this animal lacks a color vision capacity because, unlike all other platyrrhine monkeys, Aotus has a defect in the opsin gene that is required to produce short‐wavelength sensitive (S) cone photopigment. Consequently, Aotus retains only a single type of cone photopigment. Other mammals have since been found to show similar losses an…
Sociosexual Behavior and Chemical Communication of Aotus nancymaae
Cigars, Cigarillos, and Youth: Emergent Patterns in Subcultural Complexes
In order to answer questions about discrepancies in self-reported tobacco use between youth from different race/ethnic categories, the authors set out to observe and characterize tobacco use among youth in two Florida counties. Their observations and interviews led to identification of a pattern of tobacco use that had not appeared before in the literature on tobacco use, the emergent phenomenon of Black & Mild consumption, especially among Afric…
Episodic memory in primates
Episodic memory refers to a system of memory with the capacity to recollect specific events from an individual’s life. Some psychologists have suggested that episodic memory is a uniquely human phenomenon. We challenge that idea and present evidence that great apes and other primates may possess episodic‐like memory. We review criteria developed to assess episodic‐like memory in nonhumans, and how they apply to primates. In particular, we discuss…
