Comparative Functional Analyses of Mixotrophy among Microbial Eukaryotes

The ability of many single-celled, eukaryotes (protists) to combine photosynthetic and heterotrophic nutrition in a single cell is well established, but the phylogenetic breadth and tremendous ecological significance of this behavior is not widely acknowledged. ‘Mixotrophy’ is pervasive evolutionarily and ecologically. Mixotrophic behavior ranges from heterotrophic supplementation of predominantly phototrophic nutrition, to phototrophic survival of predominantly heterotrophic species under food-limited conditions, but a complex mixture of behaviors exists between these extremes. Specific benefits of heterotrophy in mixotrophic algae include the acquisition via phagotrophy or osmotrophy of carbon, energy, major nutrients (N,P) and various micronutrients (e.g. vitamins, metals, specific lipids) that provide these species with a competitive advantage over purely autotrophic species.

Pier-Based Monitoring of Harmful Algal Blooms

This research project is a collaborative effort of five harmful algal bloom research groups along the California coast that are working together with the Southern California Coastal Observing System (SCCOOS) to provide monitoring for toxic and noxious algae along the California coast. The USC component carries out weekly monitoring of harmful algae, nutrients and algal toxin concentrations at Newport Pier.
