Abstract
The authors of the three reviews of seasonality/aseasonality came to similar conclusions. Aseasonality is not apparent, the ultimate climatic factors associated with seasonality are temperature and day-length and differences between the Northern and Southern Hemispheres are, following Ward (this volume), of degree rather than of kind. This last conclusion has the inherent pitfall that it is too easily misinterpreted as meaning that there are really no important differences between the seasonal responses of Northern and Southern Hemisphere aquatic ecosystems.
