Introduction

Biodiversity Investigation Internal Assessment May 21, 2012 Daniel Chou (S.T.) Part 1: Design Aspect 1 Defining the Problem and Selecting Variables Research Question: How does the plant biodiversity of the terrestrial ecosystem between the shore of the Links pond and 10 feet away from the shore differ? Aim: The aim of this investigation is to determine plant biodiversity of both land next to the pond and land away from the pond to discover what the different in plant biodiversity will be. The degree of biodiversity achieved using the Simpson's Biodiversity Index. Hypothesis: Although the samples of land in the area are quite close to each other (10 feet apart) and belong to the same ecosystem, there should be a difference in biodiversity between the two samples of land; the land near the water having greater biodiversity. This hypothesis is suggested due to the land next to the shore having close access to a supply of water and it being a submarine environment, compared to land that is 10 feet further away from the shore. Independent Variable: -The various locations of the area -The season in which data is sampled -The time of day in which the data is sampled Dependent Variable: -The biodiversity of the land samples; measuring the abundance and quantity of different ...read more.

Conclusion

A possible limitation, that luckily did not occur in this experiment, was estimation of plant abundance, if the given amount of plants were simply too high to count manually. That would greatly limit the accuracy of the findings. Another possible issue was human error; that is, there may have been two distinct plant species or subspecies that was simply counted as the same species. Another weakness was that different samples were taken on different days, possibly skewing the data since data collection would not be uniform. The investigation could be greatly enhanced by simply having a greater amount of sampling in order to reduce the rate of error. Another improvement could be also increase the size of the quadrat in order to get greater surface area to evaluate. Finally, taking all data collection on the same day will in turn make the data uniform. Another concept of improvement is to increase regions of collections; perhaps having a 20 feet from the water away region for example will improve the data and allow us to view trends from 0 feet, 10 feet, and finally 20 feet away. Aspect 3 Conclusion In conclusion, the hypothesis that land nearer the water has greater biodiversity was not supported by the data collected. In reality, land further away had greater biodiversity. ?? ?? ?? ?? ...read more.
