CPAC10: Ecology of habitat

• State the method of this practical

  IV = Place your sampling (e.g. field or woodland)

  DV = Count no. of the species in each quadrat

  CV = temp, humidity, soil water content

  • Set up 50m by 50m area, to take measurements, for each place
  • Get coordinates for measurements - random number generator (random sampling)
  • At each coordinate, 1m by 1m quadrat, to cover 1 square metre
  • Count no. of species in each quadrat
  • Calculate diversity index d = $\frac{\Sigma N\left(N-1\right)}{\Sigma n\left(n-1\right)}$
  • Repeat 2 more times + calculate mean diversity index
  • T-test
• What piece of equipment do you use, if your trying to find how species composition changes (e.g. dune succession)?
