SBC LTER: Sea urchin foraging rates on giant kelp

These data describe the foraging rates of two sea urchin species ( Strongylocentrotus purpuratus and Mesocentrotus franciscanus ) on giant kelp ( Macrocystis pyrifera ) in laboratory mesocosms. Data are contained in two tables: 1) a data file describing the foraging rates of sea urchins as a function of urchin biomass where biomass was varied by manipulating the number of urchins in a foraging trial, and 2) a data file describing the foraging rates of sea urchins as a function of urchin biomass where biomass was varied by manipulating the size of urchins in a foraging trial.
