What is the importance of study of modern and Fossil dinoflagellates in terms of Paleo-environment, paleo-climate & recent ecology?

the ecological stadies with emphasis on algal assemblages .

This can lead to better understanding of many phenominon of algae, such as Red tides of toxic algae in oceans & seas and its effect on environment & ecology; food web in general. as well Cyanobacteria blooms in lakes, rivers and estuaries & its effect on aquatic ecosystems.

Ecological studies enhancement, with emphasis on algal assemblages: Examples of modern and Fossil dinoflagellates biostratigraphy in similar environmental realms, such as tropical / sub tropical areas, e.g. Gulf of Mexico, West Africa and other localities. This can lead to better understanding of many phenominon of algae, such as Red tides of toxic algae in oceans & seas and its effect on environment & ecology; food web in general. as well Cyanobacteria blooms in lakes, rivers and estuaries & its effect on aquatic ecosystems.
