Genomics-fueled approaches to current challenges in marine ecology

As a result of recent advances in genomic technology, a 'tool set' is emerging that can be used by marine ecologists to gain new perspectives on central questions in the field. Techniques such as gene expression profiling using DNA microarrays, when placed in an ecological context, stand to advance greatly our understanding of how organisms respond to abiotic and biotic stresses. Here, we target areas in which adding genomics to ecological and physiological investigations will significantly advance our understanding of crucial issues ranging from the general biological effects of environmental temperature changes on individuals and communities to the interactions between symbionts in coral bleaching. At a time when both short- and long-term perturbations of marine ecosystems are increasing in severity, this kind of integrative approach could generate new and exciting hypotheses about the functioning of marine organisms and communities.
