Theme 1: Vectors and Pathways

Vectors and pathways are the means by which species are transported from one location to another. Natural pathways include wind, currents, and other forms of dispersal in which a specific species has developed morphological and behavioural characteristics to employ. Man-made pathways are those that are enhanced or created by human activity.

Projects within this theme explore principal vectors and pathways that transport AIS into freshwater and marine ecosystems in Canada.
