The study of secondary succession in old fields has largely             emphasized the causal role of life history strategies and                       interspecific competition.  Yet the rate or pattern of succession               may be influenced by the size of the area undergoing succession                 and herbivory.  Given that herbivory is important, the intensity                of herbivory should also vary systematically with successional                  patch size.  A conceptual model will be tested which predicts                   that given a trade-off between colonizing and competitive                       abilities, succession should be slower on small patches and that                mammal herbivores should be less abundant and diverse on small                  patches, and biased toward small-bodied species.  The                           experimental study will use an archipelago of successional                      patches in eastern Kansas.  The patches span two orders of                      magnitude in area and are kept isolated through regular mowing.                 Immigration, population growth or decline, spatial patterns, and                species turnover for plants and small mammals will be documented.               The effects of small mammals on plant succession will be gauged                 using exclosures.  Patch size may also indirectly affect plant                  and animal succession through effects on resource availability                  (e.g., small patches are relatively more wind-exposed and may be                drier than large patches).  The availability of water and                       nitrogen in the system will be monitored.
