Different paths to diversity: comparing two tropical tree groups with high species diversity but very different biologies through genomic comparisons.

We are using DNA data to better understand the connectivity and recent history of populations of Quercus havardii, a Western sand dune oak.

We are using DNA data to further understand the reproductive biology of an under-studied oak, Quercus havardii, which will help inform seed collection strategies and collection management.

We collected acorns from across the range of Quercus havardii and distributed them to partner gardens to grow, research, and showcase this unique oak to the public.

We are quantifying the number of plants and seeds needed to best preserve genetic variation of 10 species of threatened trees in botanical gardens, which  will be models for future seed collections.

Oak conservation depends on our understanding of what species there are and how they will evolve in response to climate change. Understanding evolutionary history and gene flow is thus key to understanding oak diversity.
