The ecological consequences of the reduction of species diversity : experimental approaches

Creator:

Allison, Gary William

Abstract:

The influence of loss of diversity on community dynamics and ecosystem functioning has recently received considerable attention. Although study of biodiversity has a long history within ecology, empirical investigations exploring consequences of loss have been rare. Because many factors confound diversity comparisons, experimental manipulations of diversity offer the most direct...

Reduction of Species Diversity: Experimental Approaches. Abstract approved: Bruce A. Menge Abstract
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...
