As described in your textbook, the concepts of metapopulation biology and island biogeography provide a valuable framework for thinking about the optimal design of nature reserves
A major goal of reserve design is to maximize the number of species living in reserves, and a long-standing debate in conservation biology concerns the question of whether it is better to have one large reserve or several small reserves. Reference: Ref 46-3 You are working for a group that lobbies for conservation of chameleon (a type of lizard) diversity in tropical rainforests. You are asked to describe what type of land reserve you would like to have set aside for the long-term conservation of chameleons. For which of the following would you advocate? A. one large reserve because it will hold all the species of chameleons B. one large reserve because it will hold more insects that are food for chameleons C. several small reserves, the total area of which is greater than the reserve area described in answer a, because it will hold more species of chameleons D. several small reserves because chameleons are relatively small and do not need that much space
