Investigating the distribution of organisms

• the number of species or percentage cover changes within an area often because of biotic factors such as soil pH.
• and example of this is an investigation into weather the growth of seaweed depends on the distance it is found on the seashore from the tide. - we would use systematic sampling as we are looking to link a linear change
• a quadrat could be placed at regular distances along a imaginary line called a transect
• a tape measure is often used at the transect line
• Kite diagrams can be used to show the data collected in a belt transect
• the abundance of each organisms is shown by the thickness os the kite shape. the abundance is plotted above and below the central lube to make the shape symmetrical
