SUMMARY:Reconciling Gene Trees in the Presence of Incomplete Lineage Sorti
 ng and Hybridization - Nakhleh\, L (Rice)

CONTACT:Mustapha Amrani
DESCRIPTION:In this talk\, I will describe our work on two problems: \n\n1
 . Inference of species trees from gene trees whose incongruence is assumed
  to be due to incomplete lineage sorting. Here\, I will describe extension
  of the Minimize Deep Coalescence criterion to deal with gene tree estimat
 es that may be unrooted\, incompletely resolved\, or both. \n\n2. Inferenc
 e of hybridization from gene trees\, in the presence of incomplete lineage
  sorting. Here\, I will describe our work on extending the concept of coal
 escent histories to phylogenetic networks\, and how hybridization can be d
 etected despite incomplete lineage sorting under both a maximum parsimony 
 setting and a maximum likelihood setting. \n\nThe performance of the metho
 ds on both biological and simulated data will be shown.\n
