would you concentrate conservation efforts on one species with high genetic diversity and perhaps several subspecies OR would you focus on several different species each of them with low genetic diversity Why 2 Do genetically modified organisms GMOs constitute or lead to a conservation problem Why 3 You have just been hired as a conservation consultant Based on what you know from the SDCP and other research what do you believe are the most important components of an effective policy Why are these components so important to good conservation planning 4 If islands are such endemic hotspots should they be considered a conservation priority even though they comprise a small percentage of the world s land mass similar scenario for coral reefs in marine systems 5 How do advances in
