Abstract
We examined the hypothesis that pair-living, monogamous social systems evolved in environments with evenly distributed food resources, a homogenous distribution of females in space prevents males from monopolizing more than one female. Our study investigated the interplay between climatic variables (ambient temperature, rainfall), food availability (forest structure, phenology data), and infant production in a pair-living monogamous owl monkey population (322 births, 21 years, 22 groups) in the humid Chaco of Argentina. Associations between climatology and fruit availability ranged from -0.29 to 0.38, and some extreme events negatively impacted fruit availability. Variation in fruit availability was higher among years than territories, whereas infant production varied more among territories than it did across years. Our study makes specific contributions to examining the hypothetical “homogeneity” in the temporal and spatial distribution of food available to a pair-living monogamous primate and how such variation relates to infant production in the population.
Our analyses were divided into three parts. Part 1 examines the relationship between climate and food availability. Part 2 investigates how homogeneous the production of food is across territories and years. Part 3 explores the relationships between food availability and the birth of a new infant across territories and years.
The csv files contain all the data necessary for the three parts of the analysis we conducted. All code (R) for each part is also available.
