Annual aneuploids and polyploid perennials: phylogeny and diversification of the paintbrushes and relatives (Castillejinae, Orobanchaceae)

Abstract:

In this talk I will introduce my work investigating the radiation of the paintbrushes (Castilleja, Orobanchaceae) and their relatives, with a particular focus on life history evolution, changes in chromosome number, and macroevolutionary patterns of diversification. I will start from a broad phylogenetic perspective of the clade, and work towards a couple of focused questions on particular species complexes. Along the way, I will introduce some new approaches to large-scale phylogenetic data collection that we are developing to make efficient use of advances in sequencing technologies and species tree estimation using multi-locus datasets. Ultimately, we are using this system to investigate the patterns and processes of speciation in young, species-rich groups where even delimiting species boundaries can be extremely challenging.
