The invasive effects of Dreissena polymorpha on native mussels within the Great Lakes region The Great Lakes area once supported an abundant number of freshwater mussels (Mollusca: Unionacea). The invasion of Zebra mussels (Dreissena polymorpha) has decimated these populations, by outcompeting native mussels in dispersal rates, and reproduction, due to enhanced survival mechanisms. Understanding the mechanisms that have allowed Zebra mussels to out complete native fresh water mussels, will…

Aquaculture involves cultivating freshwater and saltwater populations under controlled conditions, and can be contrasted with commercial fishing, which is the harvesting of wild fish (Task Sheet).

Fisherman used to have only a rod and reel combo, since the sport has grown there are onshore setups, offshore setups, and combination setups. Onshore setups are made for fishing from the land, and mostly in ponds. If there is a reel for ponds, then it should not be taken to the lake because the gears will rust from the salt in the water. When fishing had not become popular yet, fisherman used to stick with one pole, and it would only last them a little while because they were used in improper…

Have you ever noticed the air temperatures getting warmer, storms being much larger than they used to be? These are effects of global warming because the amounts of fossil fuels that we burn on a daily bases. The emissions of all the fuels we burn clogs up the atmosphere of the earth like a blanket and heats the earth up more than it would if we didn’t burn fossil fuels because it doesn’t allow gasses to escape out into the atmosphere. With the air heating up and getting warmer, the water…
