EEB Thursday Seminar Series - New Views on Fern Phylogenetics: Updates from the GoFlag Targeted Enrichment Probe Set
Emily Sessa, Cornell University
Ferns are the second largest group of vascular land plants, with ca. 10,000, species, and they are critical components of Earth’s biodiversity – ferns can be found in nearly every type of ecosystem and habitat, from desert to rainforest. Ferns also occupy a pivotal evolutionary position as sister to the megadiverse seed plants, and they are thus the critical outgroup needed to understand the evolution of key seed plant features. This talk presents the results of a phylogenomic approach to reconstructing fern evolution, using the most highly resolved nuclear dataset to date (targeting 408 loci), and with highly targeted taxonomic sampling (including nearly all fern families and genera). This dataset allows us to explore a range of outstanding questions in fern phylogenetics, including resolving recalcitrant nodes, and comparing results between our nuclear based trees and other recent large-scale fern phylogenies based on chloroplast loci.
