Phylogenomics and biogeography of Micranthes (Saxifragaceae)

Micranthes The genus Micranthes (Saxifragaceae) has been overlooked and understudied. This is a consequence of having been incorrectly merged with Saxifraga for over two centuries, its muddled taxonomy and karyology, and the remote and isolated location of its many species in alpine and arctic areas. This research will provide the first in-depth evolutionary and systematic study of these enigmata taxa. This is being achieved through extensive and arduous fieldwork throughout North America, establishment of a living collection, cutting-edge next generation DNA sequencing, and in-depth taxonomic studies. Furthermore, a thorough systematic and taxonomic revision of the genus, coupled with the distribution of many taxa in alpine and arctic areas, will have significance in consideration of global climate change.
