Gradients of physical disturbance are central to theories of community organization yet rarely are studies performed in which physical factors are experimentally manipulated. Pothole tidepool algal communities exhibit ...

The echinoderm axial organ is located centrally, at the meeting point of the animals' "circulatory" systems. This, and its unusual histology, have prompted the implication of a number of different functions for the org ...

The relationship between nutrients and community structure is poorly understood in open-coast habitats. I created a system of artificial tidepools, of identical age and physical dimensions, at two sites that differed in ...

Predator-prey interactions have historically been studied to explain patterns of organization observed in populations and communities. They have also been important in understanding the evolution of antipredator respo ...
