Limnologists Essay

We did 3 different test to help conclude the water quality. The first testing/station i did was to see what kind of critters were living in the water. Then, my next group was to take a test to see if eutrophication was in the water. We also took

Dissolved Oxygen, pH levels, Temperature Change, Fecal Coliform, BOD, Nitrate, Phosphates, Turbidity, and Total Solids were each tested in the stream at least one time. If more time and enough supplies were given, then certain tests should be done more than once. Temperature Changes should be tested every other month because it is quick and a change in temperature can affect the health of the organisms living in the stream and therefore the quality of the stream. Temperatures can also drastically change in a short amount of time and there is a large difference in water temperatures in summer and winter. Another test that should be done every other month is dissolved oxygen because it is related to the temperature of the water. Cooler waters have a greater capacity for dissolved oxygen than warmer waters. This test is important because due to human activity and industrial processes, can increase water temperature and therefore decrease the dissolved oxygen levels. Certain organisms living in the stream need a sufficient amount of dissolved oxygen to survive. Another test that should be done more often is the

At the first station I was at, we were looking for macroinvertebrates and crustaceans. When we found one of the insects we had to determine which group they belonged in. One way to determine if the water is polluted is to look at which group the critters are mostly from. My group and I tested this by taking turns going into the creek and finding a rock to bring out. When we brought the rock out of the water and back to our group we had to make sure to turn the rock over because the critters normally live on the bottoms of the rocks and most likely would fall off if you didn’t turn it over. After we all took turns a couple of times

Government agencies carefully monitor water quality and its effect on wetlands (Reference: Environment Protection Agency Wetland Report EPA 832-R-93-005). Of particular concern is the concentration of nitrogen in water draining from fertilized lands. Too much nitrogen can kill fish and wildlife. Twenty-eight samples of water were taken at random from a lake. The nitrogen concentration (milligrams of nitrogen per liter of water) was determined for each sample. The variable in this information is nitrogen concentration (mg nitrogen/l water).

The organisms found could be grouped in 3 groups. Pollution intolerant organisms in the creek are caddis fly larvae, riffle beetles, stonefly nymphs, Dobson larvae, may fly larvae, snipe larvae, and water fleas. There are 10 moderately tolerant species living in the creek, they are: crayfish, crane fly larvae, aquatic sow bugs, dragonfly, larvae, scuds, beetle larvae, hellgrammites, fly larvae, and alderflies. The seven pollution tolerant invertebrates living in the creek are Aquatic worms, leeches, pouch snails, midge larvae, black fly larvae, flatworms, and segmented worms. The 24 different types of micro invertebrates in the creek and the number of pollution intolerant and moderately tolerant species in the creek indicate an excellent water

In the Medieval times, there were two warrior classes in Medieval Europe and Japan called samurais and knights. In Europe and Japan, both of their governments were tearing apart. When feudalism came into existence, it resulted into two warrior classes called samurais and knights. In the areas of social position, training and armor, and honor and death, the samurais and knights shared more similarities than differences.

to the body of Daphnia. For example, an experiment may test the effects of toxic chemicals on Daphnia, meaning that Daphnia can act as water quality indicators (Ren et al. 2009). The lack of Daphnia in certain areas signifies the presence of a toxic chemical, if the habitat meets the living requirements of Daphnia (Villegas-Navarro, 2003). Therefore, Daphnia act as indicators of environmental health as well as chemical responders reacting to potentially harmful

The first experiment we did to find out if the creek is polluted, was to count the macroinvertebrates in the creek. A macroinvertebrate is an aquatic insect, such as a crustacean. Different

To analyze the environmental monitoring policy and its resulting measurements in surface waters to determine the differentiation with respect to stream size and flow rate.

In Life at the Bottom, Dalrymple is suggesting that the description of the poor is changing and that using poverty and hunger can no longer fully cover all of the lower class. That new characteristics have risen, that many of the lower class have adopted. That those that are violent, those that have agonies and emptiness, and those that have horrid morals are now the way to depict the lower class. Dalrymple also argues that in order to rise out of the underclass that family ties are needed and without it there is hardly any way to do so. Dalrymple says that many of the issues that plague the underclass comes from a bourgeoisie society, that this upper class of liberals are feeding and fueling all of the problems and mentality that are

Bernard Malamud was brought up in the mid 1900s, a time period when baseball played a huge role in the lives of many Americans. Americans loved baseball because it gave them a chance to stop working and simply relax while they cheered on their favorite team. It was a time when people played baseball solely for the love of the game and the thrill of hearing the fans cheer for them. Today, however, baseball is much more corrupt, and many athletes are only in it due to their own greed and selfishness. This strong desire for money stems from some important players in the past, such as Babe Ruth and Joe DiMaggio, who were outstanding athletes and grew very overconfident in their abilities. They became so confident that they began to demand

They can find out the age of the animal, take tissue samples to find out if they have diseases and they can find out how big they are to make predictions about winter. Hunters are asked where they hunt, so the Fish and Game can see what the hunters are seeing. They can find out if the hunters are violating the

Income can become a challenge for many wildlife biologists, as the average income for a wildlife biologist in America as of May 2015 is $59,680 per a year or $28.69 per hour according to U. S. Bureau of Labor. (Cite) Given that I will have to attend a university or college form a minimum of four years to eight years to obtain a bachelors degree up to a Ph. D. The average debt from a Ph. D. is which can cause substantial finical debt becsue of average pay. When you add in providing for a family or just for your self it effects your way of living. Being a wildlife biologist some jobs will require you to have physical endurance.

This paper discovers the water budget for Berkeley, California in comparison to Terre Haute, Indiana. The two cities precipitation differs throughout the twelve month calendar year where many of the heavy precipitation months are totally opposite. Berkeley California’s winters, where the majority of rain occurs and Terre Haute, Indiana where the rainfall is observed as consistently disseminated throughout the year evenly. This paper will also magnify geographic position, climate and elevation in contrast of the two cities that reflects the water budget outlined in Project 1: Water Balance defined in

When I first signed up for this philosophy course, I didn’t do it because I wanted to, but instead because it is a required course for my major. I honestly thought that it would be a boring course, and it would be super hard to get a good grade. However, as the course progressed, it turned out to be the only class that kept my attention the full semester, and I believe the main reason for that, was that I was interested in the subjects and learning other people point of view and opinions on the subject.
