Aquatic Ecosystem: Biodiversity, Ecology And Conservation

by Mamta Rawat Sumit Dookia Chandrakasan Sivaperuman

This book brings together the latest information on the rapid advances and developments in the field of aquatic ecology. India is very rich in terms of biological diversity due to its wide range of habitats and climatic conditions. It is home to as much as 7 per cent of the world's animal species, although it only accounts for about 2 per cent of the total landmass. The present work on biodiversity, ecology and conservation of aquatic resources represents original research in the field of aquatic biodiversity, wetland ecology and its applications with reference to the country's aquatic resources. There are 19 chapters, each contributed by an expert in his/her particular field and offering novel approaches to various topics in the area of aquatic ecosystems.

Aquatic Ecosystems

by Nicholas V. C. Polunin

Concern about future supplies of fresh water to society, to meet the full range of human needs, now comes very high on the priority list of global societal issues. An overarching issue, which this book addresses, is whether global climate change is a dominant driver of change in the structure and function of all natural water-based ecosystems, or whether direct human population growth and accelerated consumption are playing an equal or greater role. This book divides the whole aquatic realm into 21 ecosystems, from those on land (both saline and fresh water) to those of the open and deep oceans. It draws on the understanding of leading ecologists to summarize the state and likely condition by the year 2025 of each of the ecosystems. Written for academic researchers and environmental professionals, the aim is to put the climate change debate into a broader context as a basis for conservation science and planning.

Aquatic Ecosystems in a Changing Climate

by Donat-P Häder Kunshan Gao

Global climate change affects productivity and species composition of freshwater and marine aquatic ecosystems by raising temperatures, ocean acidification, excessive solar UV and visible radiation. Effects on bacterioplankton and viruses, phytoplankton and macroalgae have farreaching consequences for primary consumers such as zooplankton, invertebrates and vertebrates, as well as on human consumption of fish, crustaceans and mollusks. It has affected the habitation of the Arctic and Antarctic oceans the most so far. Increasing pollution from terrestrial runoff, industrial, municipal and household wastes as well as marine transportation and plastic debris also affect aquatic ecosystems.

The authors suggest a phased approach consisting of site classification and risk assessment, followed by remediation technology selection and implementation. Effective methods for surveying bodies of water are particularly emphasized, and advancements in the development of novel transgenic plants and microbial fuel cells are put forward as effective tools against environmental contamination and industrial wastewater pollution. Readers will also find: A focus on the most recent and cutting-edge research on the topic: photocatalysis, the use of genetically modified organisms, and the use of nanomaterials A simple compendium of fundamental concepts in environmental engineering of aquatic ecosystems A detailed discussion of the advancement in remote sensing and geographic information (GIS), methodologies that make it possible to conduct large-scale water remediation studies at reasonable cost The ideal resource for researchers and students of environmental science, plant biotechnology, agricultural science, environmental engineering, and plant sciences, Aquatic Environmental Bioengineering will be a crucial resource for the remediation of contaminants in our aquatic ecosystems.

Aquatic Environmental Systems – an Interdisciplinary Approach for Scientists and Engineers

by Roger C. Viadero, Jr.

Considering that environmental science draws students and practitioners with widely varied backgrounds, there is a need for materials that help readers to grow their knowledge of fundamental principles from chemistry, physics, and biology to understand, describe, and predict the ways in which constituents (sediment, nutrients, organic matter, etc.) interact and move in aquatic systems (rivers, lakes, groundwater, and the atmosphere). Aquatic Environmental Systems: An Interdisciplinary Approach for Scientists and Engineers focuses on developing a common vocabulary and a rigorous material balance-based approach to understanding these movements and interactions. It examines the key properties of water and the ways they impact the behavior of water in the environment, providing a focused enumeration of those aspects of water structure that have direct and profound impacts on aquatic environmental systems. Features: Provides open-ended exercises to allow students to tailor work to their personal local/regional interests. Focuses on conveying understanding of the underlying principles and assumptions/limitations which are frequently underemphasized or overlooked entirely in other books. Deemphasizes straight memorization while focusing on methods that can be applied to more broad-based problem solving. Accommodates a wide range of mathematics skills and backgrounds.

The Aquatic Explorers: A History of the Fisheries Research Board of Canada

by Kenneth Johnstone

In 1898 a group of scientists, working without pay, often under hazardous conditions with only the most primitive equipment, began a systematic study of the fishes in Canada's inland and marine waters. The team operated under the aegis of a board of management which was later to evolve into the Fisheries Research Board, a scientific organization that has placed Canada among the world's leaders in fishery knowledge. This history of the Fisheries Research Board examines the aims and achievements of its research, its attempts to deal with the often conflicting demands of pure and applied science, and its confrontations with a frequently uncomprehending and dissatisfied government. The people who shaped and sustained the organization figure prominently in the account. In-depth taped interviews with senior members and employees of the Fisheries Research Board, as well as the Annual Reports and other publications of the Department of Fisheries, have enabled Kenneth Johnstone to produce a rich history of a remarkable scientific organization.
