The Paleo Indians are thought to have played a role in... - dEtailEd aNSwER-driving the mastodon to
extinction
A key difference between the exploitation of the environment by the Europeans and Native Americans
was that - dEtailEd aNSwER-Were relatively few in number (N.A.)
The primary mission of the early French explorers of the Great Lakes was - dEtailEd aNSwER-To find
a passage to the Great South Sea and Cathay
A goal in constructing the Erie Canal was - dEtailEd aNSwER-To help organize the territories west of
the original
13 colonies, make NYC a port of global significance, Connect the eastern seaboard to the interior of the
continent
A key commercial use of the Great Lakes from the days of La Salle involves: - dEtailEd aNSwER-
Transportation
The Welland Canal was constructed to - dEtailEd aNSwER-Circumvent Niagara Falls, Enable
Canada to compete with the Erie Canal, Enable ships rather than barges to reach the Great Lakes
There were two water features that had to be addressed to achieve connectivity for shipping across all
five lakes. One was Niagara Falls, the other was: - dEtailEd aNSwER-The Falls of St. Mary
, A trip through the Welland Canal - dEtailEd aNSwER-from Lake Erie to Ontario
For a given set of 100 species introductions, how many on average will become invasive? - dEtailEd
aNSwER-1
Invasive species are harmful because - dEtailEd aNSwER-of where they are
Anadromous - dEtailEd aNSwER-Spend the first part of their lives in freshwater streams and rivers,
then descent to the ocean to live as adults, and then return to the freshwater streams and rivers to spawn
and die
The sea lamprey is anadromous, meaning that they - dEtailEd aNSwER-spawn in freshwater but live
in the oceans as adults
the lamprey was so successful in the Great Lakes because - dEtailEd aNSwER-it produces so many
eggs, there were no natural predators there, they were able to colonize the upper lakes so rapidly
In the lamprey film, a key target for controlling lampreys was - dEtailEd aNSwER-the St. Mary's River
According to the lamprey film, the battle to control lampreys is - dEtailEd aNSwER-Never-ending
Applegate discovered the first lampricide by - dEtailEd aNSwER-trial and error
In the scientific method, predictions are generated from hypotheses, then tested with - dEtailEd
aNSwER-Data
The massive die-off of alewives in 1967 involved an estimated 20 billion of them and was caused by -
dEtailEd aNSwER-Their own physiology
