Experimental evolution allows addressing many classical conceptual questions in ecology, evolutionary biology and at the cross-boarder of the two fields making use of the possibility to track changes over time. Currently the field moves beyond observations in simple environments and single-populations asking questions on the effect of temporal and spatial varying selection pressures and community complexity. Increasing complexity at any level results however in a number of challenges that often can only be tackled using a combination of experimental evolution, mathematical modelling and molecular techniques. The symposium aims to bring together researcher from these different fields working on community dynamics and experimental evolution and discuss potential solutions to these problems. The meeting will be an excellent opportunity for students and young scientists to meet colleagues and to present and discuss their research.
