Taking identity-by-descent analysis into the wild: Estimating realized relatedness in free-ranging macaques

The paper estimates realized relatedness in free-ranging macaques using IBD analysis from low coverage whole genome data, revealing genetic variation within kin classes and cryptic relatives.

Sex differences in immune function and disease risk are not easily explained by an evolutionary mismatch

This study examines sex differences in immune function and disease risk across populations, finding no consistent support for the evolutionary mismatch hypothesis.

Socioecological drivers of injuries in female and male rhesus macaques (Macaca mulatta)

The paper examines how group size and sex ratios affect injury risk in male and female rhesus macaques, finding sex-specific patterns linked to competition and aggression.

Early life adversity has sex-dependent effects on survival across the lifespan in rhesus macaques

This study examines how early life adversity affects survival in male and female rhesus macaques, finding sex-dependent differences in mortality risk across the lifespan.

The biology of aging in a social world: insights from free-ranging rhesus macaques

This paper reviews how social adversity affects aging in rhesus macaques, focusing on ecological and social factors and the impact of Hurricane Maria.

Cost and benefits of being social: examining the influence of sociality on faecal parasites in free-ranging rhesus macaques

This study examines how social relationships affect parasitic infection risk in rhesus macaques, finding that affiliative partners reduce protozoa infection risk, while social status does not.

A generalizable epigenetic clock captures aging in two nonhuman primates.

This paper develops an epigenetic clock for rhesus macaques using DNA methylation data, achieving high accuracy in predicting age across different populations and species.

Ageing in a collective: The impact of ageing individuals on social network structure

This study examines how ageing affects social network structure in rhesus macaques using empirical data and an agent-based model, finding age-related changes in indirect connectivity but no overall network structure age distribution relationship.

Within-individual changes reveal increasing social selectivity with age in rhesus macaques

This study shows that older female rhesus macaques reduce their social networks and prioritize previously beneficial partners, indicating social selectivity with age.

Social determinants of health and disease in companion dogs: A cohort study from the Dog Aging Project

This study examines how social environmental factors affect dog health across their lifespan using data from the Dog Aging Project.

Reduced injury risk links sociality to survival in a group-living primate

The paper investigates how sociality affects injury risk and survival in rhesus macaques, finding that social integration reduces injury risk but not mortality after injury.

Age, sex, and social environmental effects on immune cell composition in a free-ranging non-human primate.

This study examines how age, sex, and social status affect immune cell composition in rhesus macaques, revealing age-related immunosenescence and sex-dependent effects of social adversity.

Maternal effects on early-life gut microbiome maturation in a wild nonhuman primate

This study examines how maternal effects influence gut microbiome maturation in wild gelada infants during their first three years, showing differences in microbial composition between infants of first-time and experienced mothers.

Helminth infection is associated with dampened cytokine responses to viral and bacterial stimulations in Tsimane hunter-horticulturalists.

The paper investigates how helminth infections affect cytokine responses to viral and bacterial antigens in Tsimane hunter-horticulturalists, finding dampened immune responses in infected individuals.

Early life gut microbiome dynamics mediate maternal effects of infant growth in vervet monkeys

This study shows that early life gut microbiome dynamics, particularly reduced alpha diversity and B. fragilis abundance, mediate maternal parity effects on infant growth in vervet monkeys.

The Goldilocks Effect: Female geladas in mid-sized groups have higher fitness

The paper shows that female geladas in mid-sized groups have higher fitness due to lower infant mortality and infanticide from immigrant males.

Mediterranean Diet, Stress Resilience, and Aging in Nonhuman Primates

This study shows that a Mediterranean diet improves stress resilience and delays age-related stress responses in nonhuman primates.

Male-mediated maturation in a wild primate

The paper investigates male-mediated maturation in wild geladas, finding that exposure to novel males induces estrogen surges and affects female puberty timing.

Highly Heritable and Functionally Relevant Breed Differences in Dog Behavior

The paper identifies heritable genetic variants associated with breed-specific behaviors in dogs, linking them to brain-expressed genes involved in neurobiology and development.

Social integration predicts mitochondrial DNA copy number in rhesus macaques

The paper examines the relationship between social integration and mitochondrial DNA copy number in rhesus macaques, finding that affiliative social behavior, not dominance rank, is linked to mtDNA copy number in immune cells.
