Marine Algal Bloom: Characteristics, Causes and Climate Change Impacts

By: Santosh Kumar Sarkar

In the marine environment, single-celled, microscopic, plant-like organisms naturally occur in the well-lit surface layer of any body of water. These organisms, referred to as phytoplankton or microalgae, form the base of the food web upon which nearly all other marine organisms depend. Algal bloom is a rapid increase in or accumulation of the population of about 300 species of algae due to excess nutrients (eutrophication), and is of major global interest as it causes reduction in species diversity, abrupt changes in water quality, and discoloration of the water (green, yellow, brown or red) depending on the species of algae and the type of pigments they contain. Dying blooms can also be an environmental concern as when the cells sink and decay, bacteria break down the organic material, which in turn strips oxygen from the water. This microbial oxygen demand at times leads to very low oxygen levels in the bottom waters, harming aquatic life. Documentation of this sporadic high abundance of algae, together with the significant species richness of the diatoms, requires comprehensive studies in the Sundarban coastal environment, which is facing severe degradation due to natural & anthropogenic stressors. In addition, a better understanding of the effects of algal blooms on seafood quality, the complex biological, chemical and physical interactions and subsequent effects on trophodynamics is needed to develop strategies for effective coastal zone management. The book discusses the occurrence of harmful algal blooms (HABs) caused by the dinoflagellates of the genus Alexandrium and Karenia, or diatoms of the genus Pseudo-nitzschia, which have large and varied impacts on marine ecosystems (such as large-scale marine mortality events that have been associated with various types of shellfish poisonings) depending on the species involved, the environment where they are found, and the mechanism by which they exert negative effects. HABs represent a major environmental problem in all regions of the U.S., and their occurrence is on the rise due to increased nutrient pollution. HABs have severe impacts on human health, aquatic ecosystems, and the economy. Such blooms, known colloquially as red tides due to their red or brown hues, are increasing in frequency and magnitude worldwide as a result of changes in oceanic climate, increased coastal eutrophication and enhanced long-distance dispersal in ballast water. As such, the book offers an in-depth account of the complex biological, chemical and physical interactions of the algal blooms (both innocuous and harmful ones). It also discusses the highly topical issue of the impact of global climate change on the frequency and severity of HABs in the context of alterations in temperature, stratification, light and ocean acidification. Focusing on both basic and applied limnology, this book is a reliable and up-to-date reference resource for students, teachers and researchers engaged in the field of coastal research/management at regional and global scales.

Trace Metals in a Tropical Mangrove Wetland

Chemical Speciation, Ecotoxicological Relevance and Remedial Measures

By: Santosh Kumar Sarkar

This book offers a comprehensive and accessible guide covering various aspects of trace metal contamination in abiotic and biotic matrices of an iconic Indian tropical mangrove wetland – Sundarban. Divided into nine chapters, the book begins by discussing the fundamental concepts of sources, accumulation rate and significance of trace metal speciation, along with the impact of multiple stressors on trace metal accumulation, taking into account both tourist activities and the exacerbating role of climate change. The second chapter presents a detailed account of the sampling strategy and preservation of research samples, followed by exhaustive information on sediment quality assessment and ecological risk, instrumental techniques in environmental chemical analyses, quality assurance and quality control, along with the Sediment Quality Guidelines (SQGs). Using raw data, the sediment quality assessment indices (e.g., pollution load index, index of geoaccumulation, Nemerow Pollution Load Index etc.) and conventional statistical analyses are worked out and interpreted precisely, allowing students to readily evaluate and interpret them. This is followed by chapters devoted to trace metal accumulation in sediments and benthic organisms, as well as acid-leachable and geochemical fractionation of trace metals in sediments. The book then focuses on chemical speciation of butylin and arsenic in sediments as well as macrozoobenthos (polychaetous annelids). Finally, potential positive role of the dominant mangrove Avicennia in sequestering trace metals from rhizosediments of Sundarban Wetland is elaborately discussed. This timely reference book provides a versatile and in-depth account for understanding the emerging problems of trace metal contamination – issues that are relevant for many countries around the globe.

Loricate Ciliate Tintinnids in a Tropical Mangrove Wetland

Diversity, Distribution and Impact of Climate Change

By: Santosh Kumar Sarkar

This book is an integrated approach to present a detailed case study in order to address the taxonomic and ecological features of this planktonic choreotrich protists in an iconic tropical mangrove wetland - Sundarban. To identify each tintinnid species, emphasis is given with regards to taxonomic features accompanied by high resolution images. This work explores the interaction between man-induced stress and the impact of climate change which is threatening the tintinnid biodiversity, and suggests, for example, remedial measures by adopting sound management strategies. Tintinnids (Protozoa: Ciliata: Tintinnida) are a coherent group ecologically recognized as micro-zooplankton. They deserve special attention because of their unique biodiversity and their crucial, functional role in the marine food chain. This is a valuable reference source for students, researchers, policy planners and coastal managers engaged in the field of marine biology, microbial ecology and marine bio-resources.

Marine Organic Micropollutants

A Case Study of the Sundarban Mangrove Wetland

By: Santosh Kumar Sarkar

The proposed book features a systematic and thorough treatment of the dominant persistent organic pollutants (POP's) encountered in the tropical marine environment of the Indian Sundarban mangrove wetlands, a UNESCO World Heritage Site. Chapters provide a comprehensive and realistic account of the world’s most hazardous organic compounds. Readers will discover a detailed account of the characteristics, potential point and non-point sources, analytical techniques and the ecotoxicological relevance of selected POPs, namely organochlorine pesticides, polychlorinated phenyls (PCBs), and polycyclic aromatic hydrocarbons (PAHs). These pollutants are of considerable interest because their exposure could cause immunologic, teratogenic and neurological problems in humans and other living beings. The book is intended to serve as a reliable and up-to-date reference source for students, teachers and researchers engaged in the field of chemical oceanography, ecotoxicology and pollution management.

Sangh Aur Sarkar

Sangh Aur Sarkar: Organization and Government by Santosh Kumar

By: Santosh Kumar

This book lays out the nuances of all those stories of ‘Sangh and Sarkar’ layer by layer. Since the year 2014, there has been a wonderful example of coordination between the Sangh and BJP. Then there are many such examples like reservation, UP CM, BHU Vice Chancellor where there were possibilities of confrontation, but the matters were resolved in a few hours through dialogue. Social harmony for the penetration among Dalits, the campaign to create an intellectual movement after the JNU scandal, Pranab Mukherjee’s visit to the Sangh headquarters, the vision of ‘Future India’ from Vigyan Bhavan and finally, direct contact with three and a half lakh villages regarding the issues of the Modi government within the context of nationality not only increased the base of both the Sangh and the BJP, but the Vichar Pariwar also played an important role in preparing the ground for a bigger victory than in the year 2014. After the 2019 victory, ideological issues such as Article 370, Ram Mandir, etc. were swiftly dealt with so that commitment of those inclined towards the ideology of Sangh-BJP could be sealed. This book discusses how to take steps towards building new India by ending the gap of six decades in six years.
