Paper of the week: evolution of body size in dung flies

This week’s paper of the week is Wolf Blanckenhorn’s very nice paper in Evolution on the evolution of body size in a field population of yellow dung flies across 15 years. Flies have become smaller, despite various measures of natural and sexual selection that would have predicted selection favouring larger males and females. Interesting stuff.
