Eco-evolutionary dynamics of living systems: Applications

Living systems undergo ecological and evolutionary change. Typically, ecological and evolutionary dynamics interact, giving rise to eco-evolutionary dynamics that cannot be understood in terms of either ecology or evolution alone.

Research by the Evolution and Ecology Program (EEP) is contributing to a growing body of literature stressing the potential of eco-evolutionary dynamics to aggravate the global biodiversity crisis:

  • A study of an ongoing invasion of winter moth in northern Fennoscandia [1] showed how eco-evolutionary dynamics can exacerbate risks by inflicting drastic changes on the invaded ecosystem (Figure 1).
  • EEP research contributed to a better understanding of invasion processes by synthesizing two leading theories, resulting in a new theoretical framework in which different invasion scenarios can be contrasted and studied [2].

  • As anthropogenic activities are remolding the native habitats of species at an accelerating pace, understanding the potential of species to respond to environmental changes is important. Researchers showed that an individual’s ability to adjust its behavior or morphology in response to environmental variations changes nonlinearly with age [3].
  • In a related counterintuitive finding, it was demonstrated that mating systems common among animals may detrimentally impact the ability of individuals to change their behavior or morphology in response to environmental variations [4].
  • With species ranges being determined by the ability of organisms to adapt and disperse, it is important to understand differences in dispersal strategies. Researchers demonstrated how dispersal strategies change with competition, costs, and the degree of maternal investments [5].
  • In a complementary study, it was shown how dispersal strategies can either stabilize or destabilize ecological communities [6].
  • In a novel application of eco-evolutionary dynamics to individual development, published by the top-ranking journal Proceedings of the National Academy of Sciences of the USA, EEP research contributed to resolving the long-lasting question why the number of spine bones is so strongly conserved across mammals [7].
  • Reliably predicting biodiversity requires understanding the mechanisms that facilitate species coexistence. Drawing on the theory of adaptive dynamics, researchers demonstrated that an often-touted coexistence mechanism is in fact rather unlikely to support coexistence in nature [8].
  • In a complementary contribution, researchers demonstrated that the observed coexistence of asexual and sexual reproduction strategies in the Amazon molly (Poecilia formosa) is possible only through mixed reproduction strategies. If the prevalence of asexual reproduction is high, eco-evolutionary dynamics may drive the population to extinction in a process known as evolutionary suicide [9].

  • In a study published in the journal Nature Reviews Genetics, current knowledge on how genomic properties influence speciation was reviewed [10].
  • The spread of diseases is determined by a complex interplay between the movement of susceptible and infectious individuals. By modeling city commuters, it was shown that intervention strategies for vector-borne diseases should often be focused on nearby villages [11]. In a complementary effort, it was demonstrated how to implement effective intervention strategies prior to actual disease outbreaks in the Tokyo metropolitan commuter network [12].
