Trade-off between market and ecosystem services drives settlement decisions among smallholder ranchers in Baja California Sur, Mexico
Historical Mortality Dynamics on the Baja California Peninsula
Decision-making under climate shocks and economic insecurity
Firewood and Energy Sovereignty on Navajo Nation
Climate-induced drought jeopardizes future access to sufficient energy sources for many people reliant on firewood, especially those underrepresented in forest management decision-making. To identify where interventions might be most effective in facilitating self-determination and sustained firewood harvest, we investigate the case of Diné firewood harvesters. Using data from surveys, interviews and participant observations, we articulate who us…
Development of a graphical resilience framework to understand a coupled human-natural system in a remote arid highland of Baja California Sur

NDVI predicts birth seasonality in historical Baja California Sur, Mexico
Birth seasonality is a phenomenon whereby populations can be characterized by a single month or season in which births peak. While non-human animal research suggests that seasonal birth-pulses are related to variation in climate and local energy availability, social scientists debate the mechanisms responsible for it in humans. Here we investigate the role of precipitation, temperature, and energy availability on seasonal conception and birth pul…
Frail Males on the American Frontier
While sex ratios at birth (SRB) have been shown to vary within and across populations, after over a century of research, explanations have remained elusive. A variety of ecological, demographic, economic, and social variables have been evaluated, yet their association with SRB has been equivocal. Here, in an attempt to shed light on this unresolved topic within the literature, we approach the question of what drives variation in SRB using detaile…

Tracking Cross-Cultural Gender Bias in Reputations
While ethnologists have long noted that females lack access to social capital across cultures, the magnitude of this effect is rarely examined. Here, we investigate the nature of gender bias in one dimension of social capital, reputation. We extract data on reputations from the electronic Human Relations Area Files (eHRAF) database, specifically the societies in the Standard Cross-Cultural Sample, and analyze whether there are fewer instances of …
Marriage dynamics in old Lower California
It is commonly expected that natural selection will favor earlier reproduction, yet ecological constraints can force people to delay marriage. Furthermore, humans demonstrate sex-specific preferences in marriage partners - with grooms normally a few years older than their brides; however, the age at which individuals marry can influence the spousal age gap. We investigate factors influencing age at first marriage and age difference at marriage us…
Cultural multi-level selection and biological market theory explain the coupled dynamics of labor exchange cooperation and social support
Maternal foster families provide more stable placements than paternal families
Anointing variation across wild capuchin populations
The frequency of anointing bouts and the materials used for self‐ and social anointing vary across capuchin species in captivity, but there is little published data on capuchin anointing in the wild. Here we present previously unpublished data on anointing behaviors from capuchin monkey populations at ten different field sites and incorporate these data into a review of the anointing literature for captive and wild capuchins. Using a comparative …
Competitive Altruism Explains Labor Exchange Variation in a Dominican Community
Smallholder farmers rely on labor exchange to generate agricultural work when cash is rare and credit unavailable. Reciprocal altruism, biased by genetic kinship, has been implicated as the mechanism responsible for labor exchange; however, few empirical tests confirm this proposition. Competitive altruism could be operating if people differ in ability and use this information as a criterion for partnership selection. Labor exchange data are pres…
Sex differences in cooperation
Although it is commonly believed that women are kinder and more cooperative than men, there is conflicting evidence for this assertion. Current theories of sex differences in social behavior suggest that it may be useful to examine in what situations men and women are likely to differ in cooperation. Here, we derive predictions from both sociocultural and evolutionary perspectives on context-specific sex differences in cooperation, and we conduct…

The Dual-Role Method and Ultimatum Game Performance
The dual-role method (DRM) extracts subject preferences as two players in experimental economic games. Previous research indicates mixed effects of DRM on game performance. A two (role)-by-two (role order) design for the ultimatum game (UG) was implemented in a naturalistic setting across 2 years. Subjects played according to the role they were assigned (proposer or responder). Immediately after, they played as the other role. Meta-analyses show …
Lithic Core Reduction Techniques
We define diversity in core reduction systems as the degree of deviation from the most efficient means to proceed from the start to the end product exhibited in a given core reduction system. Because lithic core reduction systems are often characterized along a continuum of high or low degree of diversity, some archaeologists have suggested that assemblage diversity is linked to raw material availability and quality. In this paper we provide a mo…
