Download or read book Loricate Ciliate Tintinnids in a Tropical Mangrove Wetland written by Santosh Kumar Sarkar and published by Springer. This book was released on 2014-11-24 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Trace Metals in a Tropical Mangrove Wetland written by Santosh Kumar Sarkar and published by Springer. This book was released on 2017-08-09 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Marine Algal Bloom Characteristics Causes and Climate Change Impacts written by Santosh Kumar Sarkar and published by Springer. This book was released on 2018-05-02 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Coastal Marine Ecosystems of Latin America written by U. Seeliger and published by Springer Science & Business Media. This book was released on 2000-10-18 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coastal and marine ecosystems, some severely degraded, other still pristine, control rich resources of inshore environments and coastal seas of Latin America's Pacific and Atlantic margins. Conflicts between the needs of the region's nations and diminishing revenues and environmental quality have induced awareness of coastal ecological problems and motivated financial support for restoration and management. The volume provides a competent review on the structure, processes and function of 22 important Latin American coastal marine ecosystems. Each contribution describes the environmental settings, biotic components and structure of the system, considers trophic processes and energy flow, evaluates the modifying influence of natural and human perturbations, and suggests management needs. Although the focus of the book is on basic ecological research, the results have application for coastal managers.

The book will be of interest to a wide range of readers including students, researchers and professionals in coastal ecosystem science, coastal pollution, climate change adaptation, biodiversity conservation and environmental management.
Download or read book The Biology and Ecology of Tintinnid Ciliates written by John R. Dolan and published by John Wiley & Sons. This book was released on 2012-09-13 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: Planktonic protists both produce and consume most of the primary production in the world ocean. They not only play key roles in the oceans but also represent an astounding amount of diversity: ecological morphological and genetic. However, for most taxa their ecology, morphology, phylogeny and biogeography are either poorly known or appear to be largely unrelated to one another; this hinders our understanding of their biology as well as interpretation of emerging genetic data. Tintinnid ciliates represent a singular exception. Compared to nearly all other groups of planktonic protists, there is a very substantial and relatively detailed literature (both modern and historical) on tintinnids. This volume synthesizes knowledge concerning a wide variety of topics ranging from anatomy and systematics, physiology, behavior, ecology (including ecological roles, predators, parasites, biogeography, and cysts) to fossil history. It will appeal to an audience ranging from advanced undergraduates to researchers in the fields of Oceanography, Marine Biology and Microbial Ecology.
Download or read book The Ciliated Protozoa written by John O. Corliss and published by Elsevier. This book was released on 2016-04-20 with total page 474 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Ciliated Protozoa: Characterization, Classification and Guide to the Literature, Second Edition presents a premature major overhauling of the systematics of the Ciliophora sensu lato, which is considered a separate phylum. This book includes a developed rationale and defined criteria that serve as a basis for the reclassification of the ciliates. Discussions of controversial taxa are provided, including arbitrary but critical resolution of their place in, or rejection from, the new overall system. The ideas concerning the evolution of ciliates, as well as "phylogenetic trees are also covered in this text. This text categorizes the ciliates into three classes—Kinetofragminophora, Oligohymenophora, and Polyhymenophora. This publication is a good source for biologists and students interested in ciliates.
