Lessons from Mediterranean olive domestication: keep wild relatives close by and do not “overselect”
New study in the journal BMC Biology found that Mediterranean olives have almost as high genetic diversity as olive cultivars
Flowering plants spelled the end of gymnosperm dominance
Coupled with the negative effects of global cooling, angiosperms pushed gymnosperm extinction past the point of recovery.
Polyploid plants take a leaf out from the invasive species book
The extent to which propagule pressure limits the establishment of local polyploid populations remains to be determined, because we know so little.
State of the World’s Plant & Fungi Collections (Part One)
Plant and fungal collections are seeing new and innovative uses, as well as reaching a broader user-base as digitized specimens, but significant gaps remain.
Complex evolution in an East Asian Magnolia species
Genetic incongruence hints at either ancient hybridization or incomplete lineage sorting.
Systematics of extinct grass species resolved with sequencing of 167-year-old herbarium specimen
The work is part of a trend of increasingly ambitious genetic work on old specimens.
Coordinated evolution of leaf and root anatomy in epiphytes
With both leaves and roots of epiphytes exposed to the atmosphere, can these plants be used as a model to explore co-evolution of root and leaf anatomical traits?
Greater Eucalyptus hybridisation on younger, more disturbed landscapes
Older landscapes are expected to be home to older, more genetically well-defined taxa with greater reproductive barriers.
Floras of the Future: A look at Flora of North America Online
Staying up to date and making all treatments machine-readable will broaden the project’s appeal, but it’s no small feat.
Stay in the loop.
