Bolstad, G.H. et al. 2014. Genetic constraints predict evolutionary divergence in Dalechampia blossoms. Philosophical Transactions of the Royal Society of London B 369, 20130255.

Whether or not patterns of genetic variance and covariance among traits constrains the evolution of complex characters remains a central question of evolutionary biology. This paper develops theoretical predictions concerning the effect of genetic variance on patterns of population divergence under different models of the adaptive landscape, and test these predictions on data from the species complex Dalechampia scandens. Populations tend to diverge along directions of high genetic variance especially for trait tightly integrated, although other directions also display strong capacity to evolve. This study highlights the importance of genetic architecture to predict evolutionary trajectories. 

There is now considerable empirical evidence that evolutionary changes in many phenotypic characters such as body mass, age at maturation and timing of breeding, often occur in populations subject to intense harvesting over longer periods. Here we analyze the evolutionary component of the response due to non-selective harvesting, which will operate even under selective harvesting and may generate a large evolutionary response under density dependent selection. Our model suggests that even non-selective harvesting generates r-selection governed by genetic variation in strength of density-regulation and the magnitude of population fluctuations. We show that r-selection caused by non-selective harvesting is proportional to the mean fraction of the population harvested, and that the more ecologically sustainable strategies also produce smaller evolutionary changes.
