* well, in Canada (and other deglaciated regions), all we have is 
dispersalist biogeography, so all ranges whose limits are identifiable 
barriers would count as dispersalist "facts."

On the James Bay Expedition in 2002, it certainly looked, as we went 
north through Quebec east of James Bay, like lakes were inhabited by 
random subsets of the molluscan fauna, presumably depending on which 
species had dropped off of migrating Birds. This is a disperalist 
hypothesis which could be independently tested by some hardy individual 
with a good tolerance for biting Diptera.
