- An endeavor to introduce the biological species concept into paleontologic species has been explored by many progressive paleontologists. But, no such contribution has ever been made in paleophycology.

- As most of the primary production in freshwater systems comes from algae, and given that there are many thousands of algal taxa, it is not surprising that paleophycology has played a leading role in paleolimnology.

- We dedicate this special issue to all aspects of quantifying species abundance and the subsequent elaborations of it in paleophycology.
