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.
