Alewife

The plankton of Crystal Lake had been quantitatively sampled by the researchers in 1942 before Alosa was introduced. Resampling 10 years after Alosa had become abundant revealed plankton similar in composition to that common in the lakes with natural populations of Alosa pseudoharengus and unlike that characteristic of Crystal Lake before Alosa became abundant. The plankton of four lakes with natural populations of Alosa was sampled for comparison with that of Crystal Lake in 1964, and the plankton of four lakes, without Alosa, in the "alewife" region of southern Connecticut was sampled for comparison with the Crystal Lake plankton of 1942. The plankton of Crystal Lake in 1964, when Alosa aestivalis was abundant, was quite like that of the natural alewife lakes, and not at all like the plankton of Crystal Lake before Alosa was a significant element in the open-water community. Crystal Lake in 1942 resembled the lakes without alewives in that its plankton was dominated by Diaptomus and Daphnia. Thus this showed that the majority of the zooplankton are less than about 0.6 millimeter in length when Alosa is abundant, whereas the majority of specimens of the dominant species in the same lake before Alosa…

Sometimes drastic measures need to be taken to prevent an even more drastic situation, and that is the dilemma today's scientists are facing on the topic of the Alewife, a small silver fish who have wreaked havoc on freshwater ecosystems across Ontario. The invasive species were first spotted in Lake Ontario in 1873, having been carried over in the ballast water of ships. They quickly reproduced in those bodies of water, then bypassed Niagara Falls through the Welland Canal By 1960, they had…

Dr. Matthew Ogburn focused his research on two kinds of river herrings, the Alewife and the Blueback Herring. The present research concentrates mainly on this species as it has drastically suffered a decline in existence as well as becoming endangered species. Thus, for this reason they are the module species in this investigation. River Herrings are known species to spawn in fresh water but live most of their lives in the ocean. They are also known to migrate between freshwater and ocean water…

Brewers played a vital role in feudalism. Ale was very important to the people in the middle ages. Almost everyone drank ale in the Middle Ages. It was what people chose to drink the Medieval England at the time because it was more affordable than wine. Each household required a large supply of ale at a time. A family of about 5 people would need 8¾ gallons a week. They provided a lot not nutrients as well as hydration (Kerthjalfadsson, Tofi). In the Middle Ages clean water was a luxury and…

I love both of these search engines and with an Ohio State login they are free. Just wanted to say that in case you wanted to let future students about those informational sources. 1 = The site displays a list of invasive animal and plant species in the great lakes basin since the 1800’s. This also describes the steps that the EPA (Environmental Protection Agency) is taking in order to reduce the risk of potential invasive species. This data is formatted in a manner that is easily understood to…

steps. After literally bumping into two very surprised friends (because Boston is where such serendipity happens) I journeyed out to my undergrad school, University of Massachusetts-Boston. It was nine o’clock by the time I wandered down its quiet Harborwalk and found a bench to mediate with the bay’s moonlit waters by. (UMass Boston is a seaside campus). I thought upon this town’s sense of intimacy; of the sadness of having left it, of the desires that kept me away and made me long to return. A…

incorrectly. Williams discusses, that contracted verbs tend to be dropped, and other individuals tend to contract them. William explains, the more casual that individual becomes, he will contract or delete more and more frequently depending on his linguistic background. William points out, the word ain’t is ungrammatical, yet it is still used today in the casual speech of many highly educated individuals. The word ain’t is contracted by am not and have not and it can use the form of be. Even…

your boat it is a good investment. otherwise watch for debris floating by . One to two mph is about the speed of a man walking at a slow pace. This should be the speed of your boat, not your lure. Why? Because you don't want to use a steady trolling speed. As you're trolling your crankbait, move your rod tip forward to speed the lure up, the let the weight of the lure pull the rod tip to the back of the boat. The end result will be a lure rushing through the water four to five miles per…
