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

4. How to design a conservation study 1.Define the questions -...

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

6. Start writing a model to answer your research questions Y= aX 1 + bX 2... Y= response (biodiversity measure) X= explanatory variables collinearity is the evil!!!

7. 2. Define the study area
