The effects of biomechanical and ecological factors on population and community structure of wave-exposed, intertidal macroalgae

Creator:

Blanchette, Carol A.

Abstract:

I examined the biomechanical factors that influence the sizes of intertidal macroalgae by studying a population of Fucus gardneri at Fogarty Creek Point, OR. I constructed a mathematical model to predict optimal sizes and probabilities of survival for Fucus under conditions of high and low wave exposure. Predicted optimal sizes...

Marine herbivore-plant interactions : the feeding ecology of the sea slug Placida dendritica

Creator:

Trowbridge, Cynthia D.

Abstract:

The feeding ecology of a common temperate mesoherbivore, the oligophagous sea slug Placida dendritica (Gastropoda: Opisthobranchia: Ascoglossa), was examined from April 1985 to June 1989. Along the central coast of Oregon, Placida consumed three host species: the low intertidal green algae Codium setchellii, C. fragile, and Bryopsis corticulans. Individual slugs...
