Chapter 2 Study Questions

  1. How can biologists determine if there are limits to the number of species that can be supported in local areas? Why is local species richness dependent, in part, upon regional species richness? How can we find out which processes dominate the interactions between local and regional species richness? What type of research could determine if the global number of species is still increasing (or would have increased had humans not intervened)?
  2. Evidence gathered by many ecologists suggests that intermediate levels of disturbance often act to increase the number of species found in an area. What are the implications of this finding for investigations in conservation biology and conservation strategies?
  3. How can we help foster a broad public appreciation for the splendor and breadth of biological diversity?
