Ecological genomics is an up and coming term broadly used to describe the application of genomics 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 bu analysing genomic sequences, gene expressions and genome evolution. At the core of ecological genomics is the belief that the bewildering array of interactions between species and their environments can ultimately be understood in the same terms as the commplex interactions of genes and proteins at the cellular level.
