IS2B Fall 2008 D. R. Strong Lecture 26 & 27, Study Guide Life Tables Ecological Communities. In a table, list the pairwise interspecific mechanisms that operate in ecological communities. Show negative influence of the interaction upon a species with a “-“ sign, and positive interspecific with a “+” sign influence of the interaction. Be sure to include neutralism. Compare and contrast the theories of ecological communities of Henry Gleason and Frederick Clements. Use all of the following terms in your answer: individualistic, super organism, cooperation, loose organization, highly integrated organization, interspecific. Why would we say that Darwin and Henry Gleason had completely scientific theories of communities, while the theory Frederick Clements had unscientific elements? As recounted in your textbook, explain the evidence collected by R. H. Whittaker that convinced ecology that communities were more according to the theory of Henry Gleason than Frederick Clements? In your answer explain “discreetness” of communities and independent distribution along ecological gradients. 1
