Mandi Robertson Natural History Essay Bio Young St Lawrence River Letting in Invasive species The St Lawrence once was a body of water that had its own way of working and its own life cycles.Throughout time we are seeing some little and some drastic changes. Unfortunately as humans we do make mistakes such as being very unmindful and ruining the living environment for some species. We as outsiders have let in things such as species and new creatures into our river that could potentially ruin the fish, plants and fungi that we see today or have seen in the past. Statics say since 1959 more than 186 new aquatic species have been discovered, for example zebra mussels and gobies. Each of these three having there own impact but, unfortunately mostly being negative ones. They are throwing off what was once a nearly perfect life cycle. …show more content…
It is protected by a brownish striped shell, this individual mussel was originally homed in Eurasia (Europe), but now can be found within our river, the St Lawrence. Zebra mussels are filter feeders which being so they reduce the amount of plankton for other species. In large quantities when eating they can clear the water up, which allows the sunlight to penetrate deeper into the Saint Lawrence. Zebra mussels don't eat certain types of plankton, which impacts other species greatly due to the toxic algal blooms. With clearer waters, light sensitive fish, like the walleye, swim to deeper waters to escape the sunlight. Many scientist to this day are concerned with the health of fish and birds who eat the zebra mussel. Meaning if we went back in our history this could of possibly never been a
Deep in the thick swamps and woods of Northern Gulf County, amidst the buzz and sting of mosquitoes, chirps of squirrels, and swirls of the Apalachicola, is a long-lost story. One hundred and eighty years ago the town of Iola sprang out of the cypress swamp of what is now north east Gulf County. That small community, was, and still is an enigma in the wilderness of territorial Florida and has all but faded from the memory of Gulf County and is nothing but a boat ramp now.
Robert Henry Lawrence Jr. was the first African-American astronaut to be selected for space travel. Robert graduated Englewood High School in the top 10 percent of his class. He later became an air force pilot and later was selected for space travel. Robert is considered the first black astronaut to be selected for space travel but does it count if he died before going into space? Furthermore, his name was written on the Space Mirror (which is a list of all the people who have died in space related accidents) for the astronauts those astronauts who have died. His name was first considered before going into space because they didn't know whether they were allowed to write his name on the Space Mirror because he did not physically go to
This is a quiet place in northern Connecticut, where over 11,000 people live. Established in 1768, the town's 26.8 square mile area now includes five separate villages. Trees grow everywhere, and East Windsor feels open and free, as opposed to being overcrowded and urban.
Friar Lawrence: Positive or Negative Presence? Option A According to the prompt, critics have remarked that Friar Lawrence serves as a kind of surrogate parent to both Romeo and Juliet. I agree with their statement, but whether he was a positive or negative presence is the question. While Friar Lawrence ultimately let to the character's demise, I believe he was a positive presence in the lives of both Romeo and Juliet because he listened to their dilemmas, helped them solve their dilemmas, and helped them obtain happiness.
The St. Albans Messenger has been a symbol in Franklin County for over a century. Enoch Whiting started distributed the nearby day by day news with a night daily paper in 1861. The principal article workplaces and press were situated on Kingman Street in St. Albans. Before moving to its present area at 281 North Main Street in 1959, the Messenger held workplaces in the Levy Building on Main Street downtown. Implicit 1901, the building that now houses the Messenger workplaces and printing press, was once central station for the electric streetcar line that served the city, St. Albans Bay and Swanton. The streetcar administration finished in 1921.
First of all, these shellfish get their name from the Zebra like stripes that cover its “D shape” shell. It is approximately two inches or less in length and have “sticky byssal threads that they use to attach tightly to any hard surface” (3.). When it comes times for them to reproduce, the female may produce up to 500,000 eggs in a single year. These eggs eventually develop into a small microscopic larva that will ultimately begin to form their own shells. These Zebra Mussels first landed on the map in the late 1980’s by hitching rides in the ballast waters of cargo ships. First they started showing themselves in the great lakes and from there they spread.
Freshwater mussels and water quality: A review of the effects of hydrologic and instream habitat alterations G. Thomas Watters1
Studies have repeatedly shown that as oxygen concentrations decrease, the abundance and diversity of fish decrease (Breitburg). Fish kills, in which large numbers of dead and dying fish float to the surface or wash onto shore, are probably the most dramatic and publicly visible manifestation of hypoxia and nutrient over-enrichment of coastal waters(Breitburg). In addition to mass mortalities that are easily observed, high mortality of fish lacking a swim bladder can occur leaving little or no visible evidence of fish at the surface or littering beaches (Breitburg). With no fish, shrimp, or crabs the Louisiana fishing market takes a huge hit that the economy feels in a major way. The gulf accounts for almost one-fifth of the countries fishing landings, which total to be three billion dollars (Petrolia). Fishing is not only a major part of Louisiana’s economy but also its culture. Without wildlife in our waters microorganism are given more opportunity to grow leading to bacteria infected waters. These bacteria infected waters could cause major health risks for those who come in contact with

The image of St. Nicholas has been distorted throughout time and it is important to determine who St. Nicholas really was to best understand his current personification. Many of the realities of St. Nicholas’ story have been twisted by stories that make learning about St. Nicholas difficult. Though his real life is often overlooked and forgotten because of his personification as Santa Claus today he still led an important and honorable life. The historically accurate story of St. Nicholas is very important because it greatly affected the culture. St. Nicholas’ real story can be best seen by examining his young life, and memorable works during his time as a Bishop.
The reading states that the Zebra mussels' invation to North American cannot be stopped and that poses a serious threat to freshwater fish populations in all of North America and provides three reasons of support. However, the professor states that there are ways to control the Zebra mussel spreading and doesn't have a serious threat in the environment and refutes each of the authors' reasons.
The name Matthew comes from the Greek Maththaios, which is derived from the Hebrew or Aramaic Mattiyah. His name means “gift of Yahweh” or simply “gift of God.” Saint Matthew was one of the twelve apostles and he wrote the Gospel according to Matthew. Although he was a publican, it is said the Saint Matthew was a Jew. Before his conversion, he was a publican, which was a tax collector, by profession. Not much is really known about Matthew later on in his life. His beginning of apostolic activity started in the communities of Palestine. He wrote for his countrymen in Palestine and composed his Gospel in his native Aramaic. This is refereed to as the “Hebrew tongue” which is mentioned in the Gospel and the Acts of
water? Adult dreissena polymorphazebra, also known as zebra mussels, can grow to 1/4 to 1-1/2 inches long and have D-shaped shells, they often have alternating yellow and brownish colored stripes. (Department of Natural Recources) These mussels arrived in the United States through ballast water in ships and have slowly spread throughout the freshwater lakes, since then they have known to become an invasive species, and raise questions about how and whether we should stop them or not.

ABSTRACT Computers and laptops are most important in higher education. Now a day’s most of the universities are preferring laptops for using in classrooms. Laptops are very useful in many things like information gathering, data saving…etc. When compared to desktop it is easy to carry and we can perform the task quickly by using the laptop.
