Ecological genomics describes the application of genomic tools (high throughput sequencing, microarrays, quantitative PCR etc.) to solve questions of ecology. Its purpose is to increase understanding of the responses and interactions of organisms to the environment and to one another by analyzing genomic sequences, gene expressions and genome evolution. This course will give an overview over the methods utilized and the questions asked by ecological genomics with a particular emphasis on marine ecological genomics. As a PhD level course, assessment of students and participation expectations will be commensurate with the level of student experience. MarS 330 was previously entitled "Ecological Genomics" during Springs of 2014, 2015 and 2016.
