Summary of
Research
 The
overall objective of our study is to characterize genetic factors that may
affect the success of restoring surfgrass populations in Santa Barbara County.
Our proposed work focuses on two major factors. The first is the spatial
boundaries of genetically differentiated populations and the second is the
spatial distribution of male and female plants within interbreeding populations.
This information will enhance restoration efforts that aim to maintain current
levels of genetic diversity. It will be valuable not only in practical
aspects of restoration practice, such as the choice of material for restoration,
but it will also greatly increase our understanding of processes by which
surfgrass stands are maintained and restored in nature.
Our study has three specific
objectives:
1. To identify the boundaries of genetically differentiated surfgrass
populations.
2. To determine if there is genetic differentiation within populations with
respect to clone size and depth.
3. To develop genetic markers linked to gender and characterize the spatial
distribution of male and female plants within surfgrass populations.
