Introduction

Comparing the biodiversity of three plant communities Data Collection: Below are three tables showing the number of species found in each quadrat in each group.

Conclusion and Evaluation From the results we can conclude that the number of species differs from one site to another and also from one area of the site to another area of the same site. The site 1 can be seen obviously being the most diverse and the site 3 the least diverse. This may be because of the different level of supply of resources required for growth in different areas/sites, for example the fertility of soil, the water availability, and the light intensity and also pollution. These are all very important factors and plants base on their need of these resources, they choose the environment that suite them the most, and thus adopting different niche. This is why there are fewer species in one site and more in another, and the type of species differs. Despite these, season also plays an important part. In different season there are different quantity of resources available and thus the number of species also differ. ...read more.

Conclusion

The experiment can be improved by repeating the whole experiment more than 3 times to get as many results as possible or using a specific equipment for counting the number of species in a certain region. And if using quadrats, there is a need to close eyes and to let the throwing person to turn around by himself and then throw it, to make it more random. A data of resources and the environment the plants live in should also be collected, to compare and understand why there are more species and more diverse in one area than another. The experiment should also be repeated in different seasons and years to see the difference in the number of species and also to compare the number in one year's season with another year's season, to find out how the number of species changes during the year and from one year to another. Even though the results between each group differ, but the results do follow a certain pattern, so I suggest that this experiment can be carried on universally and the results can be used reliably. 03.09.2004 Biology Li Zheng Yuan ...read more.

1. Scottish Seagrass Communities of the Genus Zostera

There are approximately 60 known seagrass species worldwide. In the U.K and Scotland only three closely related seagrass species occur. The family Zosteraceae are monocotyledonous angiosperms encompassing two genera, Zostera and Phyllospadix (Cleator 1993). This paper will consider the three species of the genus Zostera, the principle genera of North Atlantic waters.

2. An investigation into whether varying light intensity at a stream affects the species diversity

As habitats become more complex, such as the large variety of plant species in the stream and the varied substrate as shelter, the population density increases which leads to a natural emigration of prey from the defined area. With no sediment involved in the cycle it results in both population

Other discoveries (from the rainforest) include cardioactive agents (Aladesnmi & Llesanmi, 1987); antiviral agents (Wachsman et al., 1987); anti-implantation agents (Kong et al. 1985) and immunostimulants (Wagner et al., 1985). Another example of the use of plants is for contraception - one of the oldest known effective plants for birth control was called silphium, a member of the Ferula genus.

The area that I have chosen for my investigation is an example of an ecosystem; this is a relatively self-contained interacting community of organisms, and the environment in which they live and with which they interact. A community is a particular area where the different species of plants and animals interact with each other.

Conductivity is a measure of how well the water can conduct an electrical impulse. It is also dependent on the water temperature and the dissolved solutes. Conductivity is affected by the presence of inorganic wastes in the water. The pollution or wastes are ions that carry out a negative charge.
