The Zebra Mussel

                                                                                Page 1 SCIE 131 Assignment 4-1 The Zebra Mussel (Dreissena polymorpha) is a shellfish native to an area in the Ukraine and Russia near the Black ocean and the Caspian Sea. In the 1700s and 1800s canals were built lucubrate the seas and into Europe to make raptus easier. Theses canals also allowed the Zebra Mussel to expand into untried areas. It appears that in 1985 or 1986 the Zebra Mussel had been introduced to the great(p) Lakes area and was discovered in Lake Erie in 1988. It is believed the Zebra mussels were carried in the ballast urine of transoceanic ships first behavior the vast lakes. By 1996 Zebra Mussels had been ensnare in all of the great(p) Lakes (Zebra Mussels in North America). The abundant Lakes provides an environment that provides the elements needed for the Zebra Mussel to thrive. Zebra Mussels are filter feeders and feed to baffle with on planktonic algae and detritus, which was abundant in the Great Lakes. The lakes water temperature inclines from 32 degrees to 86 degrees Fahrenheit and is fresh water. The Zebra Mussels range of security deposit is from a preferent 54 degrees to 68 degrees Fahrenheit. It has been discovered they give the ability to advantageously suit to superiorer water temperatures.

The Zebra Mussel will begin spawning when water temperature reach 54 degrees and continues until the temperature drops below 54 degrees. This agency the spawning harden could be as long as v months (Zebra Mussels in North America). all(a) of these factors fit into the Zebra Mussels range of tolerance thus maximizing its biotic potential. Page 2 Another factor that has lead to the fast sum up in the Zebra mussel population is the low flake of natural predators. Their high riposte rate makes it...
