Predicting Trophic Interactions and Habitat Utilization in the California Current Ecosystem

Abstract

While specifically focusing on trophic interactions affecting habitat utilization and foraging pattern of sea lions in the California Current Large Marine Ecosystem (CCLME), the long-term goal of our modeling approach is to better understand and characterize biological "hotspots" (i.e., the aggregation of multiple marine organisms over multiple trophic levels) off the U.S. west coast and in other regions where similar fully-coupled ecosystem models may be implemented (e.g., Southern Ocean). As such, our research represents a major step towards a predictive model that can provide fundamental knowledge about: (1) the spatial and temporal distribution of key marine organisms over multiple trophic levels, and (2) natural and anthropogenic variability in ecosystem structure and trophic interactions.
