  1. EXERCISE

  2. Effect of fragmentation on orthopteran communities Two main pressures: 1. Habitat loss 2. Abandonment (within-patch forest encroachment)

  3. How to design a conservation study 1. Define the questions 2. Selection of the sites and environmental data 3. Insect sampling 4. Collect the data 5. Analyse the data and answer the questions 6. Derive implications for conservation

  4. How to design a conservation study • Define the questions • -... • -... • -...

  5. Question: What do you want to conserve? Single species, communities... Question: Which are the threats? -... -... -...

  6. Start writing a model to answer your research questions collinearity is the evil!!! Y= aX1 + bX2... Y= response (biodiversity measure) X= explanatory variables

  7. 2. Define the study area

  8. 2. Selection of the sites

  9. 3. Insect sampling Sweep netting Box quadrat Transect count

  10. 4. Collect the data Community data Presence/absence or abundance How to measure diversity from this data?

  11. 4. Collect the data Environmental data Characterize the sites

  12. 5. Analyse the data Community data= f(Environmental data)

  13. 5. Analyse the data Community data= f(Environmental data)

  14. 6. Derive implications for conservation What do we need to do to protect orthopteran diversity ? Implications for management
