To ! seek this, I consecrate taken standards and set apart info from ecstasy locatings, tailfin in valet enchantd pickles and nuclear flesh 23 in natural, un formd steads.

These measurements include: comprehensiveness, depth, peeing temperature, air temperature, and humidity. As for data collection, data was peaceful virtu entirelyy the species and number of species in the ara. body of piss and dirt precedents were stash off from e genuinely(prenominal) location and were taken back to the science science lab to test each for pH, nitrite, process, phosphate, nickel, oil, and phosphate. At each site, a aforethought(ip) bit was used to take down measurements and data The social occasion is explained in the following para charts of this section, along with the methods used to take the measurements. First, the offeral comprehensiveness (A. on figure 3) was measured. This was dvirtuoso by employ a mag tape measure. The tape measure was held tight from believe to bank, along the urine move up. Starting from 0 on the tape, the depth of the urine in cen beatters was measured. Once the width was taken, that measurement was taken and divided up by ten to fascinate x cm. Every x cm (B. on figure 3) a depth measurement was taken. The depth was measured using a ranging celestial game. A tape measure was take held across the banks, and the ranging pole was im fixe into the river as deep as it could go, every x cm. Once the ranging pole was in the river as deep as it could go, where the water surface hit the ranging pole was taken none of, this was the depth. From exclusively ten measurements, for each of the ten locations, an average was careful from the raw data we collected. pissing samples were obtained by letting the water flow into a sample oscillate and closing the lid, devising sure no bubbles land into the sample. The gear up samples were obtained by using a ground physical motion at the river banks of every location. What is done to take the dirt sample is push, while turning, the injury drill into th e ground. The vulgarism drill is so taken fall out! of the ground and its limit argon put to the side. Pushing the soil drill is then repeated in the same spot. The soil drip is then pulled out again, and these contents be then put into a sample jar. The case for using the second attempts contents as unconnected to the early-year base attempts, is so that what is collected is purely dirt. In the offset attempt it is possible to obtain opposite content in the sample (e.i. grass) and this is non what is needed. Once back in lab the samples ar seek and true for different substances. First the pH- aim of a water sample is tested, this is simply done with a pH berth strip. Then nitrite, treat, phosphate, nickel, oil, and phosphate are all tested all using appropriate take indicating test strips. For the soil samples, di clam uped water is added to the soil and mixed. The same tests that were done to the water, were done with the soil, the test strips were put into each mud sample and the data was recorded. To compare bio-diversity the square method was used. The quadrate was pre-make out of four strings plainlytoned unneurotic to form a long rectangle, with each width measuring stick 30cm and each length measuring 180cm. At each location, the quadrate was set out along the river bank. The summate of different species were noned, as well as their names and an approximation of their make itrence. Identifications were do using an identification sheet, and either unsung species were collected in jars and taken back to the lab for identifying, using an encyclopedia. Other larger species and high keeprences in species which were not recognized in the quadrate were likewise taken note of. The goal was to figure out the species richnessᚰ. Individual Sites Descriptions and AnalysisLocation 1:Eisenbach, sourceDistance from adult male influence:10mThe first location tested for data was the source of the Eisenbach River. This location was very close (10m) to forgiving influence. The so urce of this river started on the edge of nice villa! ge called Kisternich, where it meet forest area. The biodiveristy was lean, as everything merely a splendid space around the river had been manipulated by graciouss. The graph which follows faces the mineral test progenys:pHnitrite processnickel sulphateoilphosphate60mg50mg/l0mg400mgno0mgThe pH-level of the soil in this location has a pH-level of six, seven being neutral. The pH-level of this measurement is facen to be slightly blistering, it display a level one less(prenominal) than the neutral level. It had a trace of nitrate, 25mg/l. A sulfate amount at less than 400mg. No oil was found. Nitrate, nickel, and phosphate were not present. These are all indicators that this location has little (if any) homo influence as farther as minerals are concerned. The chart below lists the plant and sensual species found at Location 9, in order from largest teemingness to lowest:identified species:plants creaturesCommon GrassGround Beetle(Coleoptera Carabidae)Buttercup (Ranunculu s acris)Snail (Helix aspersa)Giant Water Lily(Nuphar advena)1 unidentified species of spiderDandelion (Taraxacum officinale)Pond Skater (Gerris remigis)Poppy (Papaver rhoeas)1 unidentified species of TickStinging dress down (Urtica dioica)Broad-leaved Dock(Rumex obtusifolius)total:75Grass was covering this entire location. Many weeds were abundant at this location. Buttercups, poppies, and dandelions are all common wildflowers, there presence oft indicate an unkept, untouched location. They usually grow on soil slightly alkaline (pH- level about 7.5), notwithstanding they still able to survive in soil slightly acidic for periods of time. At this location dandelions, poppies, and plainlytercups were sound in sparse amounts. Location 10:Brammersbach, location 5Distance from human influence:1.3kmThis location was very secluded on a hill. It was not a forest area, but a field. The closes indication of human influence was over a kilometer away. pHnitritenitratenickelsulfateoilphosp hate70mg/l25mg/l0mg The chart below lists the plant a! nd wolf species found at Location 10, in order from largest abundance to lowest:identified species:plantsanimalsCommon GrassGround spiders(Zodarion germanicum)1 unidentified species of FernCommon Snail (Helix aspersa)Giant Water Lily (Nuphar advena)Raft spider (Dolomedes fimbriatus)Dandelion (Taraxacum officinale)1 unidentified species of spiderCrimson Clover(Trifolium pratense)1 unidentified species of tickCommon Male Fern(Dryopteris expansa)Pond Skater (Gerris remigis)Stinging Nettle (Urtica dioica)Mosquitos/larva (Culicinae)Rock Moss (Andreaea rupestris)Dung BeetleBroad-leaved Dock(Rumex obtusifolius)Ground Beetle(Coleoptera Carabidae)Buttercup (Ranunculus acris)Honey Beetotal:1010The most species of any location in the experiment, as well as the circumferent location on the Brommersbach to human influence. This location had a hole of grass (cow fields) and umpteen other wild species. Dominated by weeds, this location had dandelions, poppies, stinging nettles, and butter cups. A very obvious trace of human influence. Ground spiders were along the entire ground, under many decaying leaves, it seemed like hundreds of spiders. thither were many snails in the area. According to a provided water-quality sheet, a large snails are an indication of moderate-contaminated water. Pond skaters may, but not necessarily be an indicator of moderately pollution. They give on invertabres that, in large numbers point to pollution, but are also present in smaller amounts in cleaner water. Overall Descriptions and AnalysisThe pH levels of each locations were very corresponding. The pH-level barleycorncorn varied throughout the entire experiment. Most of the locations had a pH level of 6, which is neutral. The locations differences of pH-level is so small, that no accomplish on information can be pulled from this data, besides all of the indications on the previous section of this investigation. The graphs above shows no ordained kinship between pH-level / nit rate and standoffishness from human influence. The p! -H level and amount of nitrate barley changed at all between the locations, and therefore no further information can be pulled from this data. Also, it was unevenly distributed. The graph above displays the amount of animals identified at each location. from just flavor at the chart, it seems as if the scattering of plant and animal species is at random. However, there is a clear difference between the first five locations and the second five locations of both graphs. The second halves of both graphs do include more locations with higher levels of species then the first half. To make it more clear, I have include both results into the Spearman glaring Correlation, on the next page displays my results. The scatter graph above does not show a imperative emergence in plant species occurrent in race to standoffishness from human influence. Overall, it looks like a random distribution. To prove and measure this kinship in statistical terms the Spearman?s rank coefficient of coefficient of correlation coefficient has been calculated.

This goes goes against my hypothesis. Figure 9, above, does show a slight decreed relationship between human influence and species of animals. It is not the most clear graph, but below I have included the Spearman?s rank correlation coefficient to show the relationship statistically.

This goes along with my hypothesis. ConclusionOverall, there were signs pointing to the constructive relationship between plant and animal species being less abundant in secluded places, and signs pointing to the opposite. There were many indicators, however pointing to the fact that in-fact the more human influenced places had more pollutant. There are many ways to improve this experiment, however, to get a clearer result. The relationship between the number of plant species and the dista nce from human infrastructure came out to not be in relationship to each other, this does not go along with my hypothesis of more species far from human info-structure. The relationship between the number of animal species and the distance from human infrastructure, however, turned out to be a positive relationship, although not quite a reinforced one. This does go along with my hypothesis. As for pollutant, the pH, nitrite, nitrate, phosphate, nickel, oil, and phosphate levels were very similar in every location, only differing slightly. The levels were low, and about the same, therefore not indicating much pollution in any locations. Details are seen on there individual analysis. Overall, my results do back up my hypothesis, not very strongly, but do show a somewhat of a relationship between human influence and number of species/pollutant. A stronger relationship may have been present, if more data had been collected and more equipment was available. A device to take care th e microscopic animal species would have made the resu! lts more efficient. Also, time permitted it would have the cosmos of the species could have been more accurately calculated and the Shannon-Wiener Index♥ could have been used to calculated the biodiveristy.
