Fig. 1 in Do observed sex ratios in a turtle community in northern Indiana vary over 35 years (1979-2014)?

Fig. 1. Proportions of males for (A) Chelydra serpentina, (B) Chrysemys picta, (C) Graptemys geographica, (D) Sternotherus odoratus, and (E) Trachemys scripta elegans over the course of the 37-year study in Dewart Lake, Indiana, USA. Open circles indicate years when <10 individuals were captured, and closed circles indicate years when ≥ 10 individuals were captured. The vertical dashed lines indicate the transition from non-fyke net years to fyke net years, and the horizontal dashed lines represent a 1:1 sex ratio (i.e., 50% males).

Data for: Five decades of data yield no support for adaptive biasing of offspring sex ratio in wild baboons (Papio cynocephalus)

<p>Over the past 50 years, a wealth of testable, often conflicting, hypotheses has been generated about the evolution of offspring sex ratio manipulation by mothers. Several of these hypotheses have received support in studies of invertebrates and some vertebrate taxa. However, their success in explaining sex ratios in mammalian taxa, and especially in primates, has been mixed. Here, we assess the predictions of four different hypotheses about the evolution of biased offspring sex ratios in the well-studied baboons of the Amboseli basin in Kenya: the Trivers-Willard, female rank enhancement, local resource competition, and local resource enhancement hypotheses. Using the largest sample size ever analyzed in a primate population (n = 1372 offspring), we test the predictions of each hypothesis. Overall, we find no support for adaptive biasing of sex ratios. Offspring sex is not consistently related to maternal dominance rank or biased towards the dispersing sex, nor it is predicted by group size, population growth rates, or their interaction with maternal rank. Because our sample size confers power to detect even subtle biases in sex ratio, including modulation by environmental heterogeneity, these results suggest that adaptive biasing of offspring sex does not occur in this population.</p>
