Canopy Site Observation Report
All the graphs have data points which show the averages of the site between the two trials. There is a line of best fit which has a slope of r², which is the correlation value between canopy cover and the variable tested. Figure 1 shows the average macroinvertebrate rating between Trial 1 and Trial 2. The correlation value (r²) of 0.07 shows an extremely weak, negative relationship between canopy cover and macroinvertebrates. The site with 25% canopy cover had the highest average macroinvertebrate rating of 16. The lowest rating of 10 was collected at the site with 75% canopy cover. Dissolved oxygen and canopy cover is compared in Figure 2, with a weak correlation of 0.01 (r²). The highest average value of 22.5 mg/L was found at the …show more content…
There is no correlation between canopy cover and Phosphorus, as the r² is 0.004. Figure 4 shows the relationship between Nitrogen levels and canopy cover. The highest concentration is 1.36 mg/L, which was found at the site with 75% canopy cover. The lowest concentration is 0.527 mg/L with 25% canopy cover. The correlation value of 0.214 shows a weak relationship. The relationship between turbidity and canopy cover can by seen in Figure 5. The values varied by 4.01 NTU, with 75% having the highest value and 25% with the lowest. The correlation value is 0.634 which means there is a moderate relationship between turbidity and canopy cover. Materials and …show more content…
One container held only crayfish, another snails, and the last one had everything else. Crayfish and snails are in separate containers from the rest because the smaller macroinvertebrates, like Mayfly larvae and Caddisfly larvae, would hide on the crayfish and snails. After about two hours of collecting, I began to identify and count all of the macroinvertebrates I collected using a macroinvertebrate identification guide. I released all the macroinvertebrate back into the stream. I measured the length and width of the site and recorded that into my data sheet. All observations and activities were recorded in my field log for future
Conodoguinet Creek Lab Report
727 Words | 3 PagesOur group found a total of 3 critters in group 3. Throughout this experiment we found many different types of critters. Some of the critters we found are Gilled Snails, Stonefly, Water Penny, Scud, Crayfish, Pouch Snails, and many more. Since the creek is not polluted, many critters can thrive there. Another experiment we did was the Eutrophication test.

Both of these samples were taken from Salt Creek, meaning that they should have similar ppm and they did. Our second piece of evidence that shows that we have precise group data was the results of tests 3-5. The evidence for these tests was 4, 5 and 4.
Conrad's Beach Ecological Succession Report
1014 Words | 5 PagesWhen reviewing figure 3 it has been noted that most of the species are more abundant further in the woods and the most significant change is in the moss and the amount of coverage which was substantially different depending upon the distance from the dune to the woods. The numbers fluctuated - dropping slightly at 60 m and rising to its highest point at 75 meters. Trees also had a very noticeable change in their percent coverage starting below 10% and rising close to 5 percent every 15 meters. The other plants did not show any specific trend of growing more the further way from the dune but this could be due to where the quadrants were placed as each team placed their quadrat down every 15 meters which resulted in a lot of ground left uncalculated. This could be the reason for lack of trends with other plants.
Forest Acres Research Paper
329 Words | 2 PagesForest Acres is a community located in Richland County of Columbia, South Carolina. It is a community that was incorporated in the year 1935 near the waters of Dent’s Pond, now known as Forest Lake, due to John Hughes Cooper and James Henry Hammond both having real estate interests in the area. After Cooper purchased Dent’s Pond (Forest Lake) and 1,700 acres of land, Hammond purchased 67 acres from Cooper on Quinine Hill; developing it into a suburban area for local businessmen who worked in the downtown area. In order for Cooper and Hammond to name this location, a petition was signed by residents; voting on whether to name the area Forest Acres or Quinine Hill. As a result, the name Forest Acres won majority votes; making it the official
Isopod Lab Report
1285 Words | 6 PagesThe χ2 value was 0.012858, df was 3 and hence the P value was less than 0.001 which proves that this result is not a result of random probability and is in fact reliable. In Trial 3, twelve isopods (60%) made the choices of hiding behind the sucrose sponge. The χ2 value was 0.00350342, df was 3 and hence the P value was in between

Both, Table 9.7 and Table 9.8 rejected the null hypothesis of the experiment. Discussion The colored dots were used as a representation of the different phenotypes of the organism Dottus Variengatus.
Conodoguinet Creek Pollution
1455 Words | 6 Pagesphosphates and nitrates ) - which is when fertilizers < such as those on farms > can seep through the soil or even run down the soil - called runoff - into the creek causing the water to have more nutrients than it should. ) Depending on how much pollution there is depends on how much algae there is ( the more eutrophication -there is the more nutrients in the water- results in how much algae there will be.) We were also testing on the pH scale ( which measures the acidity or alkalinity of water ) goes from 0 - 14 where 6 - 0 is higher acidity and 8 - 14 is higher alkalinity ( alkalinity is what neutralizes/destroys acid. ) 7 on the pH scale is neutral and that is the ideal water for the ecosystem. The pollution that we were testing for is where the acid came from to begin with.
Cosmopolitan Canopy Research Papers
628 Words | 3 PagesThere are cities, like Philadelphia, that as time passes they start to grow in size and population as a result they have to create recreational places. As years go by, people start to interact more in recreational places until they become a cosmopolitan canopy. According to the book “The Cosmopolitan Canopy: Race and Civility in Everyday Life” by Elijah Anderson, a cosmopolitan canopy is a place that provides opportunities for new relationships to develop and where people come together to socialize and practice getting along with others. In this reading, Anderson also explains that a cosmopolitan canopy is not just created by the place itself or by the diversity of ethnicity, gender, and social class in and around it but also by the “goodwill that is expressed and experienced by most who enter these premises” (Anderson 11). Personally, I agree with Anderson because in order for something to become a cosmopolitan canopy, there has to be difference on the people in it.

Cullowhee Creek Essay
466 Words | 2 PagesWe took a large net and set it vertically in the water, and then somebody got in the creek and kicked up sediment into the net. After doing this a few times, we collected all of the creatures off of the net and into an ice cube tray. We then examined the creatures and noted the variety (or lack thereof) of the creatures. The larger the variety in the species of the creek, the healthier the creek is. We noticed several species of fly larvae such as stone fly larvae and caddis fly larvae. We also noted a few worms.
Susquehanna River Lab Report
867 Words | 4 PagesOn the trip with SWEEP the health of the Susquehanna River was studied. In order to do that, chemical test, biological tests, and physical observations were made. Chemical testing showed the more scientific side of water quality, such as the amount of nitrates, phosphates, the pH values, temperature, dissolved oxygen, and turbidity. Searching for macroinvertebrates was the biological testing. Certain macroinvertebrates and the quantity found determines how healthy the stream is.
Conodoguinet Creek Essay
490 Words | 2 PagesAlso, there was different categories of critters in the water. There are 846 critters in group 1, 288 critters in group 2, 466 critters in group 3. Due to the experiment of the water velocity, we found out that the velocity is random at each point. This is good, because it means that the dissolved oxygen levels are to be high. The crayfish, belonging to the crustacean group is plentiful in the creek.

How Does Acid Rain Affect Plant Growth
1186 Words | 5 PagesIntroduction: In this task I will be researching the effect that acid rain has on the rate of plant growth. Acid rain is any type of precipitation with a high pH, with high levels of nitric acids. The reason why I had chosen this topic was because acid rain seems to have a great effect on the effect of plant growth, and plants play a very important role in our ecosystem. Acid rain is a major problem in our environment when we are not able to neutralize the acidity.
