Biodiversity and connectivity of marine algal populations

Seaweeds contribute large amounts of dissolved and particulate organic matter to marine ecosystems, and are major structural components of near shore habitats. However, our understanding of the processes producing and maintaining seaweed biodiversity is very limited. Knowledge of these processes would benefit our understanding of the dynamics of near shore communities and their responses to natural and anthropogenic perturbations. Little is known about historic (biogeography) or present day (connectivity) patterns of kelp dispersal, and these and other factors will be important in properly assessing competing MPA network designs.

These issues are addressed by research on four important rocky shore algae (Lessonia, Macrocystis, Carpophyllum and Cystophora).

Biogeographic studies are also initiated with collaborators in Chile (S. Faugeron, Santiago) on comparing genetic patterns is common southern hemisphere algal species (e.g. Macrocystis).
We also are continuing work on discovering the biodiversity of New Zealand' s macroalgae (NIWA).
