Discuss the main concepts of island biogeography. How has it been applied to the formation of biosphere reserves?
What will be an ideal response?
In the late 1960s, MacArthur and Wilson published the Theory of Island Biogeography in which they posited that number of species on an island were positively correlated to island size, negatively correlated to island distance from the mainland (isolation), and that a dynamic equilibrium existed between species extinction and immigration, which were related to island size and isolation, respectively. Though they were discussing actual islands, they noted that these principles could be applied to fragmented landscapes, which were similar to islands. Though thinking on this matter has evolved greatly since the publication of the book, it is still considered a seminal book that laid the foundation for many of the modern principles of biological conservation.
