Data from: Disentangling the dynamics among climate, food availability, and reproduction in a pair-living, monogamous primate

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.
