Biology investigation --- Comparing the differences in the diversity of fauna species in the upper shore and middle shore

Introduction

In order to investigate the diversity of fauna species in the upper shore and middle shore, where the information can then be compared, I am going to carry out some samplings.

Hypothesis

For the upper shore, it is only covered by sea water for a very short period of time, which means that desiccation happens quickly. In other words, organisms and rocks are drying out very soon. And because of the short time in obtaining nutrients from water and the wide variation in temperature, metabolism in organisms is affected. This often leads to slow growth and poor productivity in organisms. Species living there have to be quickly adapted to such conditions. Even these problems also occur in the middle shore. But as the species in the middle shore are covered by the tide for half of the day, desiccation and variation in temperature and humidity are less severe. So we tend to find more living organisms in the middle shore because of the relatively stable environment for species.

Null hypothesis

There would be about the same number of types of fauna species in both the upper shore and the middle shore.

Equipment list

  1. wellington
  2. random number table
  3.  4 measuring tapes
  4. quadrat
  5. pictures of different fauna

Method of sampling

  1. I am going to start with the upper shore.
  2. First of all, I will throw a stone randomly onto the sky.
  3. Secondly I will determine the centre of a 100m2 square at where the stone drops and finally stops.
  4. Next I will use four measuring tapes, which all ...
