EEP research demonstrated that even optimizing selection – generally believed by experts to help species survive environmental changes – can have the diametrically opposite effect of causing extinctions . A complementary study showed that the seemingly cooperative process of conspecifics aggregating in groups to jointly overcome environmental challenges can spiral out of control and cause runaway evolution that eventually results in extinction .
Under the right conditions, eco-evolutionary dynamics help mitigate the impacts of environmental change and increase the global species pool through processes of diversification and speciation. Several studies in 2013 aimed to identify such conditions.
Figure 1. A realistic eco-physiological model is used to uncover the evolutionary history of a pair of coregonid fishes in Lake Stechlin, Germany. Speciation of a single ancestor gives rise to two new species adapted to different temperatures.
EEP’s research further elucidated how individual behavior and individual traits affect the eco-evolutionary dynamics of ecological populations and communities.
