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
