Effects of Multigenerational Exposure to Early-Life Advantage
Associations Between Prenatal Maternal Stress and Infant Resting Brain Activity
Mounting evidence suggests that maternal stress is associated with infants’ brain activity, but the role of maternal stress during pregnancy is not yet understood. The present preregistered investigation examines associations between prenatal maternal stress (physiological and perceived) and infant brain activity at 1 month of age. A sample of diverse mother–infant dyads ( N = 160) participated (55% female; 39% White). Maternal physiological stre…
The prefrontal cortex in a pandemic
The COVID-19 pandemic is an unanticipated and uncontrollable chronic stressor that is detrimental to the mental and behavioral health of children and families, particularly those from disadvantaged and marginalized backgrounds. Chronic stress impairs a myriad of prefrontal cortical functions, important for coping with the COVID-19 pandemic, and has consequences on dyadic parent-child functioning. Informed by neuroscience and clinical evidence, se…
Dominance rank predicts social network position across developmental stages in rhesus monkeys
Social network analysis is increasingly common in studying complex interactions among individuals. Across a range of primates, high‐ranking adults are generally more socially connected, which results in better fitness outcomes. However, it still remains unclear whether this relationship between social network position and dominance rank emerges in infancy and whether, in species with a social transmission of dominance rank, social network positio…

A descriptive analysis of gut microbiota composition in differentially reared infant rhesus monkeys ( Macaca mulatta ) across the first 6 months of life
The gastrointestinal microbiome is recognized as a critical component in host immune function, physiology, and behavior. Early life experiences that alter diet and social contact also influence these outcomes. Despite the growing number of studies in this area, no studies to date have examined the contribution of early life experiences on the gut microbiome in infants across development. Such studies are important for understanding the biological…
Rhesus macaques ( Macaca mulatta ) with self‐injurious behavior show less behavioral anxiety during the human intruder test
Self-injurious behavior (SIB) has been linked to anxiety in the human literature, but relatively few studies have explored this link in rhesus macaques. A widely used behavioral assessment of anxiety, the human intruder test (HIT), employs the mildly stressful stimulus of an unfamiliar experimenter to assess anxious behavior in macaques. The HIT was conducted on 59 (20 male) laboratory housed rhesus macaques, 30 with a record of SIB (10 male). If…
The well‐being of laboratory non‐human primates
The well-being of non-human primates in captivity is of joint concern to scientists, veterinarians, colony managers, caretakers, and researchers working with non-human primates in biomedical research. With increased regulatory, accreditation, and research focus on optimizing the use of social housing for laboratory primates, as well as the advent of techniques to assess indices of chronic stress and related measures of well-being, there is no bet…
Differential relationships between chronic hormone profiles in pregnancy and maternal investment in rhesus monkey mothers with hair loss in the neonatal period
Hair loss is commonly used as an indicator of well being in primate facilities, yet it has been shown to also occur in otherwise healthy pregnant and postpartum females. There is significant variability in the incidence of hair loss during these important developmental periods, reasons for which remain unclear. We studied female rhesus monkeys ( Macaca mulatta , n = 47) with and without hair loss in pregnancy/postpartum. We hypothesized that, sim…
First‐time rhesus monkey mothers, and mothers of sons, preferentially engage in face‐to‐face interactions with their infants
Face-to-face interactions between mothers and infants occur in both human and non-human primates, but there is large variability in the occurrence of these behaviors and the reason for this variability remains largely unexplored. Other types of maternal investment have been shown to be dependent on infant sex (e.g. milk production and maternal responsiveness) and maternal experience (e.g. symmetrical communication). Thus, we sought to determine w…
Reproductive consequences of a matrilineal overthrow in rhesus monkeys
Matrilineal overthrows in macaque societies are rare but devastating events, often resulting in severe morbidity, mortality, and loss of individual and group fitness. The handful of documented macaque overthrows provides scant evidence to reveal the severity or longevity of reproductive consequences resulting from such violent events. We analyzed archival records from semi-free ranging rhesus monkeys, Macaca mulatta, across 6 years (55 ≤ N ≤ 107,…
Quantitative Genetics of Response to Novelty and Other Stimuli by Infant Rhesus Macaques (Macaca mulatta) Across Three Behavioral Assessments
The Integrative Biology of Reproductive Functioning in Nonhuman Primates
At the 34th annual meeting of the A merican S ociety of P rimatologists in 2011, the society organized an interdisciplinary symposium entitled, “Reproductive Function & Dysfunction in Nonhuman Primates.” The articles in this special section, excluding this introduction, represent the findings presented by four of the five speakers in that symposium. The data presented highlight the myriad factors that contribute to primate reproductive function a…
Growth and developmental outcomes of three high‐risk infant rhesus macaques ( Macaca mulatta )
Infants classified as “high risk” are born with a greater chance of developing medical complications at birth, and may have cognitive and other developmental complications later in life. Very few reports exist regarding the survival and outcome of such infants in primate colonies. Here we present early growth and developmental data on three high‐risk infant rhesus macaques (one female and two males) that were born either with intrauterine growth …
