Co-existence and co-evolution

Analyses of co-existence and co-evolution

In a natural area in Israel fragmented by agricultural land, we investigate the influence of fragmentation on the population genetic patterns of different Asteraceae species. This raises the question of whether species that co-occur in areas co-exist and then co-evolve under constant conditions (test of the Neutral Theory of Evolution). Next Generation Sequencing technologies (Genotype by Sequencing) but also Common Garden experiments will show how co-occurring species influence each other.
