Chrysophytes – Taxonomy, Biodiversity and Palaeoecology Proceedings of the Ninth International Chrysophyte Symposium Yamagata, Japan September 11-15, 2016

About this book

The present volume features twelve scientific papers presented at the 9th International Chrysophyte Symposium (ICS9) in Yamagata, Japan in 2016. Ten of the twelve papers in this volume deal with chrysophytes/synurophytes, the remaining two with diatoms.

The volume is subdivided into four distinct parts: taxonomy, biodiversity, culture work, and palaeoecology. The first part includes discussion of Clathromonas and Paraphysomonas from the Mediterranean Sea, and the descriptions of two new taxa (Chrysosphaerella nichollsii from West Java and Aneumastus mongolotusculus from Mongolia), while the second part describes living assemblages in lakes, bogs or puddles from China, Russia and Vietnam.

The third part presents new data on the formation of lipids in four species of Chaetoceros, while the last part describes the use of a FlowCam for cyst morphometric studies, introduces fossil assemblages from the Southern Ocean, and revisits the naming vs. numbering problem for stomatocysts.

This volume continues the tradition of providing up-to-date information and ideas on the chrysophytes, synurophytes and related algae. It also reflects the diversity of topics that are currently being studied by specialists around the world; these include not only studies on freshwater habitats, but also marine habitats, in addition to fossil assemblages in land-based and deep-sea cores, too.
