Posterior distributions for paternity probabilities at the group level.

<p>Posterior distributions for the probabilities that fathers (at the group level) came from roosts in the (blue) upper-elevation, (yellow) mid-elevation and (green) low-elevation, and from (red) swarming sites. For (A) low-elevation offspring (the inset graph shows the Wharfedale roost posterior distributions in greater detail), and (B) mid-elevation offspring (adapted from <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0054194#pone.0054194-Senior1" target="_blank">[4]</a>).</p

Posterior distributions for paternity probabilities at the individual level.

<p>Posterior distributions for the probabilities that individual males from the (blue) upper-elevation, (yellow) mid-elevation and (green) low-elevation roosts and (red) swarming sites fathered low-elevation offspring.</p
