The microbial populations of an ecosystem play important roles in carbon fixation and nutrient cycling, and are governed by reciprocal interactions with the physical and chemical environment. Assessment of microbial populations in intact ecosystems has been improved by the development of quantitative molecular techniques for rapid analysis of microbial community diversity. Using polymerase chain reaction (PCR), diversity can be revealed through restriction fragment length polymorphisms (RFLPs). In her seminar Dr. Doherty will describe her application of molecular-size techniques work in studying microbial populations in estuarine environments. Her studies employ a combination fieldwork, laboratory culture, mesocosm experiments, bioinformatics and molecular approaches in order to understand microbial diversity and its significance.
