Social bonds, social status and survival in wild baboons: a tale of two sexes

Fernando Campos, Francisco Villavicencio, Elizabeth Archie, Fernando Colchero & Susan Alberts
People who are more socially integrated or have higher socio-economic status live longer. Recent studies in nonhuman primates show striking convergences with this human pattern: female primates with more social partners, stronger social bonds or higher dominance rank all lead longer lives. However, it remains unclear whether social environments also predict survival in male nonhuman primates, as it does in men. This gap persists because, in most primates, males disperse among social groups, resulting in...

Data from: Social bonds do not mediate the relationship between early adversity and adult glucocorticoids in wild baboons

Stacy Rosenbaum, Shuxi Zeng, Fernando Campos, Laurence Gesquiere, Jeanne Altmann, Susan Alberts, Fan Li & Elizabeth Archie
In humans and other animals, harsh conditions in early life can have profound effects on adult physiology, including the stress response. This relationship may be mediated by a lack of supportive relationships in adulthood. That is, early life adversity may inhibit the formation of supportive social ties, and weak social support is itself often linked to dysregulated stress responses. Here we use prospective, longitudinal data from wild baboons in Kenya to test the links between...

Data from: Differential impact of severe drought on infant mortality in two sympatric neotropical primates

Extreme climate events can have important consequences for the dynamics of natural populations, and severe droughts are predicted to become more common and intense due to climate change. We analysed infant mortality in relation to drought in two primate species (white-faced capuchins, Cebus capucinus imitator, and Geoffroy's spider monkeys, Ateles geoffroyi) in a tropical dry forest in north-western Costa Rica. Our survival analyses combine several rare and valuable long-term data sets, including long-term primate life-history,...

Data from: Evolution of the conodont Diplognathodus ellesmerensis from D. benderi sp. nov. at the Bashkirian-Moscovian (Lower-Middle Pennsylvanian) boundary in South China

Keyi Hu, Nicholas Hogancamp, Lance Lambert, Yuping Qi & Jitao Chen
Conodont assemblages from the Bashkirian-Moscovian boundary interval in the Naqing section, South China have been studied in detail. A landmark-based geometric morphometric analysis to study the evolution of Diplognathodus ellesmerensis is presented. This analysis helped recognize a distinct new species, D. benderi sp. nov., which represents the direct evolutionary ancestor of D. ellesmerensis. The potential of using the First Appearance Datum (FAD) of D. ellesmerensis as the Bashkirian-Moscovian boundary marker is re-evaluated via biostratigraphic correlations...
