Abstract Detail

Species tree reconstruction in polyploid complexes

Oberprieler, Christoph [1], Oxelman, Bengt [2].

Species tree reconstruction in polyploid complexes.

The proposed colloquium aims to provide a forum to present and discuss research connected with species tree reconstruction in polyploid complexes. Growing evidence for the importance of reticulation events among lineages in the evolutionary history of many plant groups have rendered our gene-tree reconstructions to be only a local optimum on the path toward the long-standing conceptual goal of systematics, being rather a tree or network of species than a tree of genes. In addition, the advent of large multilocus datasets (phylogenomics) with their large numbers of independently segregating and individually evolving loci will also necessitate the application of new algorithms for estimating species trees/networks from a number of often contradictory gene trees. The proposed symposium on species tree reconstruction in polyploid complexes will offer a unique opportunity to bring together researchers with a mix of theoretical and empirical background and at all career levels. Scientists who were contacted and who have agreed to be included into a list of potential speakers are listed below. Most of them would need financial support to contribute to travel expenses in order to allow them to participate. A full colloquium schedule (four hours of 30 minute presentations) should be easily filled with further talks on phylogenetic reconstructions in polyploid plant groups.
