Habitat (Depth) Selection in Marine Zooplankton: Theory and Experimental Tests
Abstract
LONG-TERM GOALS: My long-term goal is to achieve a predictive understanding of the vertical distribution and migration of pelagic animals in the sea by assessing the behavioral and demographic responses of zooplankton and micronekton to various combinations of food resources and predation risk. SCIENTIFIC OBJECTIVES: First, to test the predictions of a habitat (depth) selection model based on optimization theory by determining the responses of individual zooplankters to various experimentally manipulated conditions of predatory risk and potential feeding rate. Second, to extend the test of the habitat (depth) selection model to field populations of marine zooplankton (e.g., Calanus finmarchicus on Georges Bank and Acartia spp. in San Francisco Bay). A related sub-project, entitled "Predation Closure in Modeling the Arabian Sea Pelagic Ecosystem: Model Extension and Data Assimilation", in collaboration with John Steele (WHOI), has two additional objectives: 1) to extend an existing N/P/Z model and apply it to the Arabian Sea; and 2) to compile and assimilate extant field data on zooplanktivores in the Arabian Sea.
