333 controlling factors vary from one year to the next, the quantity of food available to Wood Storks can be expected to differ each nesting season. Because of the many complex interactions, the food production of wet years following dry years will differ from that of wet years following wet years and the production of dry years following dry years will differ from that of dry years following wet years. For this reason, the temporal pattern of rainfall distribution has cumulative importance, and biological events of a given year should be considered not only in the context of the climatological events of the current year but also in the context of the climatological and biological events of preceding years. Optimum conditions for prey fish production would seem to have prevailed during the 1974 wet season, since marshes such as Corkscrew were covered with water to near maximum depths from late June through October (Figure 38), but simulations from Model III (Figure 78), in which coefficients were adjusted to fit 1974 data, suggest that fish production measured at Corkscrew during the 1974 wet season was very low compared to that of some previous years. The simulations showed much higher concentrations of fish in the 1969-71 period, which corresponds to the period when Kushlan (1972) studied seasonal events at an alligator hole in the Big Cypress. Fish concentrations at the alligator hole (Kushlan, 1976) greatly exceeded those measured during the dry-down at Mud Lake Pond in 1974-75.
