EPISODIC EVENTS, SEDIMENT RESUSPENSION, AND THE DEVELOPMENT OF A RESTING EGG 'SEED BANK' MODEL
 
The development of a seed bank of resting eggs depends upon yearly production, hatching schedules, survival during burial, and long-term viability. In low sedimentation regions, losses from benthic consumers may limit the development of a seed bank, whereas in productive waters with high sedimentation, the numbers of viable resting eggs may be impressive. Large storm events are important in purging a portion of the buried eggs from the seed bank, resurrecting both ancient genotypes (intraspecific component) and species (interspecific component). On the scale of decades to centuries, the frequency of episodic events could be important for maintaining genetic and community diversity. Examples from small (Lake Michigamme, Portage Lake) and large (Lake Michigan, Lake Superior) lakes are used to clarify aspects of the model development.
