Sources of fitness interdependence associated with shared fate and cooperation in a small-scale horticultural society
Child and adolescent foraging: New directions in evolutionary research
Young children and adolescents in subsistence societies forage for a wide range of resources. They often target child-specific foods, they can be very successful foragers, and they share their produce widely within and outside of their nuclear family. At the same time, while foraging, they face risky situations and are exposed to diseases that can influence their immune development. However, children's foraging has largely been explained in light…
Does Wealth Predict Health Among Dogs in a Protected Area
As the world's most ubiquitous carnivore, domestic dogs maintain unique proximity to human populations. Partly because dogs potentially serve as hosts of zoonotic diseases, determinants of canine health are increasingly the focus of interdisciplinary research. Emerging perspectives suggest that dogs' health may vary as a function of their owners' wealth and financial resources, a correlation that could potentially inform public health programs an…
Timing, Initiators, and Causes of Divorce in a Mayangna/Miskito Community in Nicaragua
There exists a paucity of evolution-oriented research focusing on why relationships end, particularly in comparison to the substantial literature centered around individual preferences that define the beginning of relationships. In contrast, there is a long tradition in the fields of sociology and family studies of exploring divorce; however, this body of research is largely limited to studies of Western populations. We address these gaps in the …
Statistical Methods and Software for the Multilevel Social Relations Model
The multilevel social relations model (SRM) is a commonly used statistical method for the analysis of social networks. In this article and accompanying supplemental materials, we demonstrate the estimation and interpretation of the SRM using Stat-JR software. Multiple software templates permit the analysis of different response types, including binary, counts, and continuous responses
Patterns of paternal investment predict cross-cultural variation in jealous response
Dietary variation among indigenous Nicaraguan horticulturalists and their dogs: An ethnoarchaeological application of the Canine Surrogacy Approach
Behavioral Ecology, Human
Human behavioral ecology (HBE) is an adaptationist approach to the study of behavior. Its primary goal is to understand how behavior varies as a function of local socioecological context. HBE relies on a hypothetico‐deductive research strategy to test simple models using empirical data, often from small‐scale societies. Research in HBE covers a wide range of topics but mainly focuses on behaviors that are most directly related to Darwinian fitnes…
Economic and demographic predictors of dietary variation and nutritional indicators in Nicaragua
These results indicate that, although there is a relationship between diet (δ 13 C and δ 15 N) and socioeconomic variables, these dietary differences are not the main cause of health differences in this population
Applicability of the Investment Model Scale in a natural-fertility population
Relationship quality is a construct that is central to theories of relationships and one that is used widely by psychologists. However, all prior assessments of relationship quality have derived from samples living in industrialized nation states. Here, the authors expand the breadth of this cultural variation to examine the means, reliability, and structure of the Investment Model Scale (IMS) in a sample from a natural-fertility, subsistence-lev…
Wisdom of the Elders: Ethnobiological Knowledge across the Lifespan
A common assumption is that individuals continue to accumulate ethnobiological knowledge throughout their lives, resulting in greater expertise among the elder generations. Alternative theoretical perspectives suggest that ethnobiological knowledge about animals should peak earlier in life, paralleling and facilitating the emergence of foraging proficiency among younger adults. We test these competing models among indigenous Nicaraguans with thre…
Multilevel modeling analysis of dyadic network data with an application to Ye'kwana food sharing
Behavioral ecologists have recently begun using multilevel modeling for the analysis of social behavior. We present a multilevel modeling formulation of the Social Relations Model that is well suited for the analysis of dyadic network data. This model, which we adapt for count data and small datasets, can be fitted using standard multilevel modeling software packages. We illustrate this model with an analysis of meal sharing among Ye'kwana hortic…

Using Multilevel Models to Estimate Variation in Foraging Returns: Effects of Failure Rate, Harvest Size, Age, and Individual Heterogeneity
Living with Kin in Lowland Horticultural Societies
Postmarital residence patterns in traditional human societies figure prominently in models of hominid social evolution with arguments for patrilocal human bands similar in structure to female-dispersal systems in other African apes. However, considerable flexibility in hunter-gatherer cultures has led to their characterization as primarily multilocal. Horticulturalists are associated with larger, more sedentary social groups with more political i…
Effects on Household Labor of Temporary Out-migration by Male Household Heads in Nicaragua and Peru: An Analysis of Spot-check Time Allocation Data Using Mixed-effects Models
Learning Aspects of Hunting Via a Conformist Bias Could Promote Optimal Foraging in Lowland Nicaragua
Given the complexity of human foraging strategies, especially hunting, recent attention has focused on the ways in which hunters acquire needed knowledge and skills, including via social learning. One potentially useful heuristic is a “conformist bias,” in which individuals identify and adopt the most common beliefs or strategies, but the usefulness of this heuristic depends on the accuracy of the information. In this study, 45 indigenous Mayangn…

Sources of Stable Isotope Variation in Archaeological Dog Remains
Assessment of the δ 15 N ratios and δ 13 C isotope values of archaeological dog and human bone collagen, ethnoarchaeological dog bone collagen, and ethnoarchaeological dog and human hair protein demonstrates that these tissues can be used to show subtle differences in diet between households at the same site. While δ 13 C isotope values for dog and human bone and hair protein can be used as evidence of C 4 photosynthetic plant foods, it is not ne…
Hunting Dogs in the Lowland Neotropics
Once absent in much of Amazonia, dogs are now commonly used for hunting throughout the lowland Neotropics. Although some ethnographers have questioned their usefulness, dogs are particularly effective in pursuits of several mammalian prey species. The return rates of hunting with dogs appear to compare favorably with those of hunting with firearms, and dogs may be especially beneficial in anthropogenic habitats. There is considerable cross-cultur…
Hunting with Dogs in Nicaragua: An Optimal Foraging Approach
Although dogs are used by subsistence hunters in many locations throughout the world, hunters with dogs have not been studied from an optimal foraging perspective. A study of indigenous Mayangna and Miskito hunters in Nicaragua indicates that the use of dogs affects both the encounter rates and the pursuit times of several prey types. Before hunters can identify the prey type and initiate a pursuit, they must first catch up to the dogs, and their…
