Write 7 pages thesis on the topic fresh water fieldwork related to different aspects on eco-system. Basing on the pond profile generated as below, it is indicated that different plant species had different abundance at different water depths of the pond. The study was carried out on the basis of the following hypotheses. .
The data was collected on biota and biota parameters of two riverine sites known as Dean Brook Walker Fold Wood and Ravedon Brook on the Smith estate. The results were analyzed and presented by comparing and contrasting the two sites. Before these, transect across the pond was taken whereby the plant species abundance was recorded at 1m intervals across the pond. Also, water depth was recorded at a 1m interval. Later, a pond profile had to be generated using the data produced from the above process. The analysis of the data was done through SPSS whereby t-test and multivariate analysis were utilized.
Basing on the pond profile generated as below, it is indicated that different plant species had different abundance at different water depths of the pond (Everard and McInnes, 2013). Juncuseffusus is seen to have less abundance at a high water depth. this is similar to bare ground, Rorippa nasturtium-aqua tecum, and Iris pseudacorus. On the other hand, Lemna minor is seen to be evenly distributed across different water depth levels. On the other hand, Hydrocharismorsus-range species are observed in large numbers at deepwater levels (Everard and Moggridge, 2012).
In regard to the first hypothesis, the 2 samples have been used. the sample came from different plant species that are not matched. In this case, the samples are independent of each other. Therefore, the appropriate test for testing this hypothesis is an independent sample t-test, which is used to find out if there is any statistically significant difference between the biota and biota data parameters between Dean Brook Walker Fold Wood and Ravedon Brook on the Smith estate.
Table 1 provides descriptive statistics for each of the two given groups .we have 5 for Dean Brook in the 0(VAR2) (N) and on average, they have 0.3206 VAR1 with a standard deviation of 0.30397. We also have 5 Radeon Brook in the 1(VAR1) (N) and on average, they have 0.082 with a standard deviation of 0.06261. The last column shows the two groups’ Std error means.
