Limnologists Essay

I’ve always had a keen interest in science. When I was younger, I viewed a dolphin show online. I was instantly fanisnated and later I was informed that the trainers were special marine biologists. The idea of becoming a marine biologist is still a dominate career choice for me. Last year, I was incredibly curious with the aspects that a marine biologist has to undertake that I researched the career path as part of my PLP. This only ignited my interest even further and when I was invited to attend the Flinders University I particularly focused on the marine biology and biology lectures.

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

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

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).

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

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

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

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

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.

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.

Bioindicators of stream health include blackfly larvae, caddisflies, and algae. The presence of blackfly larvae indicates sewage pollution. Caddisflies indicate higher  O2 concentrations. The presences of algae can indicate different things. If algae is absent, there may not be enough nutrients to support its growth. Thick algae indicates eutrophication.  Previous studies by the Colorado Department of Health Water Quality Control Commission in 1981 show comparable amounts of dissolved  O2 as well as pH, nitrite, and nitrate levels in both Cherry and Bear creek. The  NH 3 levels were much higher in Cherry Creek at .10 mg/L compared to Bear creek where the  NH 3 levels were at .06 mg/L (Colorado 1981). In today’s society, it is important to find a balance between preserving the natural ecosystem and accommodating the wants, needs, and desires of the humans who affect it. (Meyer 1997). Pollution is inevitable but should be considered and kept as low as reasonably achievable.

The monitoring program includes field and laboratory components to identify sources of materials (nutrients, sediment, microorganisms, and chemicals) to the lake, evaluate in-lake water quality conditions, and examine the interactions between Onondaga Lake and the Seneca River. Onondaga County’s trained technicians collect water quality and biological samples at a number of key locations in the watershed. Streams flowing into Onondaga Lake are monitored to estimate the annual input of water and materials including nutrients, sediment, salts, and bacteria. Samples are collected upstream of the lake to help pinpoint sources of pollution. Accurate estimates of inflows are a critical component of the AMP, since they underlie many of the management

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
