I am interested in how species interactions and succession structure
marine communities. More specifically asking questions concerning
which species of algae recruit after a disturbance and why they
recruit when they do. Ulva (sea lettuce) is a common alga
that recruits soon after a disturbance on the rocky shores of central
California. The blades of this alga are annual and holocarpic, meaning
that all cells within the blades can become reproductive simultaneously.
This trait has led to the theory of an eternal source of propagules
that are always in the water column. I’m in the process of
testing which is the more prominent factor in Ulva’s
efficient colonization of bare rock; spores in the water column
or microscopic stages, and whether timing of disturbance has an
effect on recruitment. Contact info: Rosemary Romero
