Jason Addison is Professor of Biology at the University of New Brunswick. His research examines evolutionary genetics and speciation mechanisms in aquatic ecosystems, combining population genomics with biogeographic approaches. Current projects investigate genetic structure in marine amphipods (Corophium volutator) across the Bay of Fundy and freshwater insects throughout Atlantic Canada.
Research focuses on how life history traits, dispersal barriers, and historical processes shape population divergence. Work on Strongylocentrotus sea urchins reveals how reproductive isolation mechanisms maintain species boundaries in sympatric lineages. Methodological expertise includes coalescent-based analyses of mitochondrial/nuclear DNA to reconstruct demographic histories and gene flow patterns.
Recent publications apply genomic tools to conservation challenges, including sturgeon sex marker validation and shorebird diet analysis via DNA metabarcoding. His lab employs field sampling across marine and freshwater habitats combined with genomic sequencing and spatial statistics.
