Data from: Effects of female group size on the number of males in blue monkey (Cercopithecus mitis) groups
<p>The number of males per group varies substantially in group-living primates, both between and within species. In blue monkeys (<i>Cercopithecus mitis</i>), males may temporarily join groups during annual mating seasons when sexually receptive females are present. A likely determinant of the number of males per group is female group size (the number of adult females in a group). To clarify the role of female group size in driving variation in the number of males per group, we expanded on earlier observations of a wild population in the Kakamega Forest, Kenya with a larger sample of groups that varied five-fold in female group size. We found considerable flexibility in social organization, with groups experiencing multi-male episodes both during and outside mating seasons, some persisting over multi-year periods. The dichotomy between single- and multi-male mating seasons was less distinct than previously reported, suggesting greater variation in multi-male states. Across 65 group-specific conception periods, female group size strongly influenced how often multiple sexually active females and multiple males were present in a group. The number of sexually active females present on a given day related closely to the number of males in the group that same day, especially during conception periods. Results suggest that males join and remain in larger groups where mating opportunities are greater and costs of joining or staying may be lower than in smaller groups. This longitudinal study highlights intraspecific social variation within and across groups while confirming that female group size influences the number of males.</p>
Data from: Female investment in offspring size and number shifts seasonally in a lizard with single-egg clutches
The timing of reproduction strongly influences reproductive success in many organisms. For species with extended reproductive seasons, the quality of the environment may change throughout the season in ways that impact offspring survival, and, accordingly, aspects of reproductive strategies may shift to maximize fitness. Life-history theory predicts that if offspring environments deteriorate through the season, females should shift from producing more, smaller offspring early in the season to fewer, higher quality offspring later in the season. We leverage multiple iterations of anole breeding colonies, which control for temperature, moisture, and food availability, to identify seasonal changes in reproduction. These breeding colonies varied only by the capture date of the adult animals from the field. We show that seasonal cohorts exhibit variation in key reproductive traits such as inter-clutch interval, egg size and hatchling size consistent with seasonal shifts in reproductive effort. Overall, reproductive effort was highest early in the season due to a relatively high rate of egg production. Later season cohorts produced fewer, but larger offspring We infer that these results indicate a strategy for differential allocation of resources through the season. Females maximize offspring quantity when environments are favorable, and maximize offspring quality when environments are poor for those offspring. Our study also highlights that subtle differences in methodology (such as capture date of study animals) may influence the interpretation of results. Researchers interested in reproduction must be conscious of how their organism's reproductive patterns may shift through the season when designing experiments or comparing results across studies.

Raw fitness data (offspring number and weight), main dataset for manuscript: Female-specific resource limitation does not make the opportunity for selection more female biased
<p>The present dataset contains the entirety of the raw empirical data used in the manuscript entitled: "Female-specific resource limitation does not make the opportunity for selection more female biased". This data is composed of offspring count and weight, which represent proxys of fitness. Fitness was assessed for males and females independently, and across three different experimental treatments. These fitness measures are used to calculate the opportunity for selection, as the variance in realtive fitness. Detailed methods regarding data collection can be found in the main manuscript.</p>
