Landscape Patterns And Forest Island Interactions, Forest Sterns, James B. Levenson, Paul Matthiae
Field Station Bulletins
On March 18, the Field Station welcomed faculty and graduate students involved in the Landscape Pattern Analysis project. This study has both theoretical and practical objectives. The theoretical problems are concerned with island biogeography as outlined by Robert MacArthur and E. O. Wilson were discussed in the Spring 1975 Field Station Bulletin. These questions relate principally to how island size and distance from neighboring islands affect species composition and extinction, i.e., affect the diversity of island communities. These theoretical questions are being approached in a series of studies undertaken jointly by scientists at the Oak Ridge National Laboratory, Rutgers University, …

Ecosystems develop as a result of interactions between the biotic and abiotic components in the environment. Natural systems are diverse and stable when interactions between the community and the supersystem are in balance. Change or perturbation in the supersystem will effect a commensurate change in the natural subsystems. Urbanization results in the remaining natural systems becoming isolated within the urban system-a supersystem quite unlike that which gave rise to the natural system. As a result, the natural subsystem must change in the way in which it interacts with its new supersystem to reach equilibrium. A mechanism for such change in …
