Buskey 9314036 This study will examine the effects of food quantity and quality on the growth, feeding and bioluminescence of several species of Protoperidinium. Selective feeding of these pallium, feeding dinoflagellates (which capture large food particles extracellualarly) and the role of sensory perception in this selection process will also be examined. In addition, the study will determine the abundance of heterotrophic dinoflagellates in the western Gulf of Mexico, and examine the relationship between growth rate and bioluminescence capacity for field collected Protoperidinium incubated at ambient food concentrations. ***

本研究将研究食物的数量和质量对几种毛藻生长、取食和生物发光的影响。我们还将研究这些白斑藻的选择性摄食、摄食鞭毛藻（在细胞外捕获大的食物颗粒）以及感官知觉在这一选择过程中的作用。此外，该研究将确定墨西哥湾西部异养鞭毛藻的丰度，并研究野外收集的在环境食物浓度下孵育的prooperidinium的生长速度与生物发光能力之间的关系。＊＊＊
