Competition Of Resources In The Campus Lakes
General Research Question: Will competition affect resources available in Campus Lakes?
Population Ecology Experiment
Null Hypothesis: The presence of blue-green algae will not have on effect on the Chlamydomonas population.
Alternative Hypothesis: The presence of blue-green algae will have an effect on the Chlamydomonas population.
Community Ecology Experiment
Null Hypothesis: Nitrate concentration will not have an effect on chlorophyll levels in the Campus Lakes.
Alternative Hypothesis: Nitrate concentration will have an effect on chlorophyll levels in the Campus Lakes.
Methods
Population Experiment First, nine test tubes were obtained. One test tube was used for the control (chlamydomonas), …show more content…
Previous sections of Biology 1209 went to the LSU lakes and collected samples from various locations including the Campus Lakes. From these samples we measured the chlorophyll levels and nitrate concentration. First, a chlorophyll determination test was done using a Buncher funnel. The lake water was filtered through the fuel and then filter paper was placed into a test tube to which acetone was added. This test tube was placed in a vortex and the filter paper removed before being placed in the spectrophotometer to measure the absorbance level. Another test tube was filled with the lake water, and in this tube we added a nitrate reagent, shook the test tube, and allowed the tube to incubate for 10 minutes. The solution turned red, showing the presence of nitrate. The nitrate concentration was then read and recorded through the scale window. The color match determined the accurate value of nitrate. From this data and data taken from previous years (Spring 2008 to Fall 2016 data), the values were plotted to show the correlation between chlorophyll levels and nitrate concentration in the Campus Lake water …show more content…
On there own, chlamydomonas and the blue green algae increase in population every week except for a slight dip during the third week. When placed together in the same test tube, both species benefitted from being together as indicated by the larger population when compared to the species being separated. This graph shows a trend of both chlamydomonas and blue-green algae having larger populations when placed in the same test tube throughout all four weeks of the experiment. According to the data found, it appears that chlamydomonas and blue green algae benefit each other when placed in the same
