Dinoflagellates are fascinating protists, mostly unicellular,
distributed in environments ranging from the polar to tropical
seas, hypersaline, coastal, estuarine and oceanic waters. There are
about 2,377 dinoflagellate species recognized. They exhibit a great
diversity of shape, size, biochemical composition and physiological
characteristics. Generally free floating, dinoflagellates are
photosynthetic, a few species such as the Symbodinium are
symbiotic, living in corals, while a few are parasitic. This volume
presents a discussion on dinoflagellate phylogeny based on recent
developments in molecular biology. It provides insights into the
similarity of pigment composition with other microalgae. A
comprehensive coverage of their carbon assimilation rates is
presented, which appear to be low compared to other microalgae.
Besides photosynthetic assimilation, an interesting aspect of
acquiring carbon is through mixotrophy which appears to be wide
spread amongst dinoflagellates and a thorough discussion is
presented. Key features of this book include recent methods of
culturing dinoflagellates, which can serve as analogues of their
blooms in understanding their physiology, biochemistry and
production of phycotoxins. This book, based on massive data
collected over decades of research, provides an informative
overview on the spatial and temporal distribution and dispersal of
dinoflagellates by ocean currents, ballast water introductions and
climate changes. About 70 species of dinoflagellates are implicated
in the production of ephemeral harmful algal blooms (HABs), which
are on the increase globally. Based on several case studies, a
comprehensive coverage of the phycotoxins produced by HAB species
(PSP, DSP, ASP, Ciguatera, NSP) is presented. The adverse effects
of phycotoxins on human health, and the loss of revenues ($50
million in the USA) due to fish kills are evaluated. Latest
advances in the methodology of genomics are presented with a view
to highlight their importance and to understand their linkage with
phycotoxin production. A discussion of remediation measures to
manage HABs is presented, which would be highly useful in
aquaculture operations. This book provides a large number of
illustrations, microphotographs and color photographs. It is ideal
for any audience requiring an in-depth exposure to current issues,
ideas and methods used in dinoflagellate studies. The topics
discussed serve as a useful reference to researchers, scientists,
environmental managers, undergraduate and graduate students.
