Distribution and abundance of species

Students practise sampling methods which can be used in the field (supports OCR Unit 14 and AQA Unit 16).

This resource contains:

  • Simulating investigations of the distribution and abundance of non-mobile species - PRACTICAL SHEET 
  • Simulating the mark–release–recapture technique (Lincoln Index) for estimating population sizes of mobile species. Modelling a sampling procedure to investigate the abundance of mobile animal species that mix freely with each other in the field - PRACTICAL SHEET
