Succession and stability in two rocky intertidal communities on the central Oregon coast

Creator:

Farrell, Terence M.

Abstract:

The stability of a limpet-dominated community was assessed in a experiment in which an consumer was temporarily removed. Compared to unmanipulated plots, the limpet-exclusion plots developed greater algal abundance and altered species composition of both algae and barnacles. The community was not perturbed beyond its capacity to recover, since the...

Bottom-up and top-down forces in tidepools : the influence of nutrients, herbivores, and wave exposure on community structure

Creator:

Nielsen, Karina Johanna

Abstract:

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 wave exposure, and manipulated nutrient levels and the abundance of herbivores. Using these unique field mesocosms, I explored...
