Description
Summary:Characterization of the diets of upper-trophic pelagic predators that consume forage species is a key ingredient in the development of ecosystem-based fishery management plans, conservation of marine predators, and ecological and economic modeling of trophic interactions. Here we present the California Current Predator Diet Database (CCPDD) for the California Current region of the Pacific Ocean over the past century, assimilating over 190 published records of predator food habits for over 100 predator species and 32 categories of forage taxa (species or groups of similar species). Literature searches targeted all predators that consumed forage species: seabirds, cetaceans, pinnipeds, bony and cartilaginous fishes, and a predatory invertebrate. Diet data were compiled into a relational database. Analysis of the CCPDD highlighted differences in predator diet data availability based on geography, time period and predator taxonomy, as well as prominent prey categories. The top 5 forage taxa with the most ... : CCPDD Location GIS files for polygons and pointsThese files can be used to link data from the CCPDD to GIS shape files using the field LocatNum.CCPDDlocationdata_v1.zipCCPDD Predator Prey Link DataThis file includes the data from the California Current Predator Diet Database (CCPDD) that was used for the analysis of forage species in predator diet in our publication. Each record (row) includes data for predator and prey taxonomy, citation info, location, date, observation type, sample size and units for measuring amount of prey consumed.CCPDDlinkdata_v1.csv ...
