Opis

India has 7,500 km of coastline with diverse habitats and rich biota. Coastal ecosystems, unfortunately, are experiencing wide range of pressures due to siltation, eutrophication, coastal development, aquaculture and climate change. Those species that adapt to these pressures will expand their living boundaries while others may fade away. Accordingly, the study of coastal biodiversity is of great concern globally and constitutes an important element of global change research. Gujarat has 1,600 km of coastline, reportedly with rich diversity of seaweeds. Previously published accounts on seaweed biodiversity were mainly in the form of checklists, the earliest among these being the checklist of Krishnamurthy and Joshi prepared in the early 1970s. The more recent checklists are based almost entirely on secondary information. The present book entitled Seaweeds of India The Diversity and Distribution of Seaweeds of Gujarat Coast is a timely publication based wholly on primary data. Data were collected through extensive and systematic ? eld studies conducted by the authors during different seasons over a three year period. The authors collected nearly 200 species of seaweeds belonging to 100 genera of Chlorophyta, Phaeophyta and Rhodophyta. Twenty-four of the species are new to Gujarat coast and three are new to Indian waters. The book contains high-quality images of the different species in their existing habitats. Brief taxonomical descriptions, together with information on ecology, distribution, seasonality and abundance, are covered for each of the species."

From the reviews:

"Recent years have seen the appearance of a number of color field guides describing the seaweeds of various locations, the market now possibly close to the point of saturation. ... The stated intended audiences include teachers, researchers, students, industries, and policy planners interested in algal resource management, utilization, and conservation ... . This book includes descriptions and photographs of about 142 species ... ." (John M. Huisman, Journal of Applied Phycology, Vol. 22, April, 2010)

This book is first of its kind from India and describes a total of 198 species of marine macroalgae representing all three major groups of Chlorophyta, Phaeophyta and Rhodophyta collected from the Gujarat coast which is well known for its algal abundance and diversity. All species described in this book are based on primary collections exclusively made for this purpose and truly reflect the current status of seaweed biodiversity of Gujarat coast. For easy identification, high resolution colour pictures of each species in its natural habitat together with well spread habit of thallus with cross sections showing characteristic features of respective specimens have been provided. Further, the taxonomical descriptions along with distribution and GPS data, abundance, ecology, economic importance etc. have also been included. The contents of this book are user friendly and provide most reliable baseline data on seaweed biodiversity for monitoring and evaluating the impact of any coastal developmental activities aimed at long term economic gains or environmental changes as a result of global warming and climate change. This book will serve as an authentic field guide and reference material for students, teachers, researchers and policy planners interested in algal resource management, utilization and conservation.
