The origin and identity of invertebrate organisms being transported to Canada's Pacific coast by ballast water
We assessed the colonization risk of invertebrate nonindigenous species (NIS) in ballast water being brought into Canada's Pacific coast by indirect and direct methods. Initially we mapped the locations in the northern Pacific Ocean where ships coming into Vancouver Harbour had performed mid-oc...

We assessed the colonization risk of invertebrate nonindigenous species (NIS) in ballast water being brought into Canada's Pacific coast by indirect and direct methods.
