SUMMARY:Sara Lowes\, University of California San Diego\, Title: Culture at a Crossroads: Traditional beliefs in Contemporary Africa
DESCRIPTION:Sub-Saharan Africa is experiencing large-scale cultural change. Christianity has spread widely and is now nearly universally adopted by non-Muslim populations. Despite this\, traditional spiritual beliefs remain deeply rooted and continue to ground social\, economic\, and political life. Descriptive accounts– especially by African scholars– suggest that Christianity’s universal doctrine\, which posits a single god and a single path to salvation\, has had adverse consequences for traditional beliefs. We examine this relationship using data from the DRC and across Africa. Text analyses of sermons reveal that traditional customs and beliefs are frequently mentioned and almost always portrayed in a negative light. Behavioral experiments in the DRC show that individuals known to hold traditional beliefs are treated less prosocially and that antisocial norms and negative stereotypes support this behavior. Such effects are not found for any other characteristic; they appear among all subgroups of our sample; and they intensify with economic development. Patterns in cross-Africa survey data are consistent with the Congolese experimental findings. Finally\, consistent with Christianity being a source of these effects\, we find that in both the experiments and surveys\, the findings are stronger in areas with more exposure to colonial missionary activity.

SUMMARY:Lee Koren\, Bar Ilan University\, Title: Sex\, survival\, and steroids: Lessons from 27 years of rock hyrax research
DESCRIPTION:In this talk\, I will share what I have learned about how endocrine mechanisms interact with environmental and social factors to shape variation in fitness-related outcomes in a wild social mammal. Drawing on nearly three decades of data from free-ranging rock hyraxes (Procavia capensis)\, I will discuss how male reproductive tactics are associated with divergent investment in sexual signaling\, sperm production\, and reproductive success\, mediated in part by testosterone. I will then present results showing that male longevity is explained by the interaction between testosterone and cortisol. Throughout the talk\, I will also discuss evidence for sexual conflict that has emerged from our long-term study and consider the importance of examining sex differences through long-term studies of animals in their natural environments. Together\, my findings highlight the role of hormones in mediating mating strategies and life-history trade-offs and demonstrate how phenotypic flexibility can arise from the integration of intrinsic condition and extrinsic pressures in a complex social system.

SUMMARY:Joon Hwang\, University of California Santa Barbara\, Title: How does human mobility across scales shape responses to environmental and social pressures?
DESCRIPTION:Mobility has long enabled humans to access dispersed resources\, inhabit diverse environments\, and sustain social connections across communities. Mobility also operates across spatial and temporal scales\, from everyday movement to larger-scale relocation and migration\, echoing the distinction between logistical and residential mobility among hunter-gatherers. This talk brings together three lines of research spanning this broad mobility spectrum to examine how different social and ecological contexts shape human mobility and how these forms of mobility in turn enable or constrain people’s efforts to sustain livelihoods and respond to environmental and social pressures. First\, I examine remittances as a form of hybrid mobility connecting migrants with those who remain in origin communities through financial transfers\, exploring how spatial patterns of climate risk shape these connections and their implications for recipients’ risk perceptions\, adaptation\, and well-being. Second\, I shift the focus from migration to daily mobility among Shodagor fisher-traders in Bangladesh\, examining how everyday movement mediates associations between climatic stress and daily income\, and how these pathways vary across seasons and livelihood activity. Third\, I examine everyday mobility among enslaved people on a nineteenth-century Georgia plantation\, exploring how labor assignments and surveillance structured movement and how both movement and interruptions to labor could create opportunities for resistance. Together\, these studies highlight how mobility across spatial and temporal scales shapes access to resources and opportunities for action in diverse contexts\, with its costs and benefits depending on environmental conditions and power relations governing movement and labor.
