Yasoma D Hulathduwa B.S.in Zoology,University of Sri Jayewardenepura, Sri Lanka, 1999. Ph.D Louisiana State University May, 2006 E-mail [email protected] [email protected] Research Work I am interested in examining the factors that affect commensal organisms of oyster reefs. During the past four years I have looked at how hydrocarbons, salinity and tidal height play a role in colonization of oyster reefs by various species. I have also worked on bio-energetics of two mud crab species (Panopeussimpsoni and Eurypanopeus depressus) found among the reef community in Gulf of Mexico. In these studies, measurements of oxygen consumption, ammonium excretion and food consumption are measured across a salinity gradient and converted to energetic equivalents to determine sub-lethal effects of salinity. Competition among these two mud crab species is also an interesting aspect I am working on. My current experiments lead to understand how the competitive ability of these two species varies in different salinities. Personal I was born & raised in Colombo, Sri Lanka-a beautiful island in the Indian Ocean. I like to read, swim and travel. I also enjoy my time with my family; there’s never a dull moment with my husband Cecil & my two year old son, Yasith.
