Introduction

Aspects of the Ecology of the Shingle beach at Greatstone and the Rocky sea shore at Copt Point 2010. INTRODUCTION We visited Copt point at Folkestone and Greatstone near New Romney, both on the south coast of Kent to look at the diversity of species in an environment. Copt point is an area of undeveloped cliffs is not protected except naturally by material from falls cliffs. There is no need to defend this coastline as long as cliff top development is restricted. It is undesirable to defend the coastline here because of the geological importance of the cliffs. The seashore is of conservation importance for its marine life. Greatstone - The sandy beach at Greatstone is quite flat and stretches from north to south for over two miles, and is frequently 'washed' by the tide of the English Channel. Greatstone Dunes separate the beach and sea from the land along almost the length of Greatstone. It is a Site of Special Scientific Interest with many rare species of plants. This is one of the biggest shingle peninsulars in the world Simpson Diversity Index Beach Side: 1- (27300/40200) = 0.3208955224 House side: 1- (121361/575322) = 0.7890555202 Adaptations of Plants to their Environment False Oat Grass is a very common species of grass which is often used as an ornamental plant. ...read more.

= 71.2 ?(110.66 +67.64) t = 5.33 The null hypothesis shall be rejected, this suggests that the environment does affect the height of inflorescence of False Oat grass and it is not random. Standard Minimum Method of Insect Population The graph shows that the first sweep captured the more insects than any others. The line of best fit suggests that there is a negative correlation. As the number of sweeps increases the amount of insects captured decreases. Wood Sage Dispersion Index Number of Wood Sage observed in 20 randomly placed 0.25m2 quadrats. 6 0 0 0 0 0 10 0 10 12 5 0 0 0 7 23 0 12 0 0 Mean = 85 / 20 = 4.25 Standard Deviation = 6.3484 Variance = 6.34842 = 40.302 40.302 / 4.25 = 9.48 = Population Dispersion Conclusion The population dispersion has a value of 9.48 which allows me to conclude that the wood sage is clumped together because population dispersion value is greater than 1. COPT POINT Algae has adapted along the sea shore mainly due to conditions of the tide and the terrain of the specific beach, for e.g. rock coverage. Algae on the shore consist of many seaweeds or wrack. At Copt point the lower shore consisted of roughly 20 metres of rock and shingle. The lower shore has stable conditions and is exposed only at low tides. ...read more.

This is then divided by 173 - 17 to give 1.65 (17 X 475.5) / 173 - 17 = 1.65 There is a significant correlation between temperature and the number of species according to our calculations In conclusion the temperature correlated in a significant way with the number of species at the given metres. This makes sense as there are more species along the shore that are suited to warmer conditions (often outside of the water) ...read more.

    This is not a realistic thing to do, so we use samples. The best method of sampling to use will be random sampling. This way the results are not biased and I can get quite an accurate number of the density of limpets on the shores.

    the fronds are similar, and are not affected too much by abiotic factors. * To control these variables it would be best to collect sample data on the same day and time; as abiotic factors such as light, temperature and humidity etc vary from day to day.

    At the top (splash zone) there are no marine species as there is hardly any water, which is essential for the survival of marine species. There is a sparse diversity of life near the top of the rocky shores. However, the biomass increases as you go down the shore as there is richer, thicker seaweed and more crustacean life due to less harsh abiotic factors.

    As the concentration of pectinase increases, the number of active sites will also increase. Provided that there is an excess of substrate molecules, the rate of reaction increases in proportion to the concentration of the enzyme, thus resulting in a higher yield of apple juice passing through the measuring cylinder.

  2. Effects of temperature on the development of a bean plant.

    The movement of water into the aleurone layer causes the activation of hydrolysis enzymes. These enzymes degrade the stored proteins into amino acids3. The gibberellic acid activates the gene responsible for encoding the enzyme amylase. The amino acids that are produced through hydrolysis are used to create the amylase enzyme during translation3.
