| freshwater algae identification and use as bioindicators: Freshwater Pollution and Aquatic Ecosystems Gowhar Hamid Dar, Khalid Rehman Hakeem, Mohammad Aneesul Mehmood, Humaira Qadri, 2021-12-23 This new volume addresses the environmental impacts of pollution on freshwater aquatic ecosystems and presents sustainable management and remediation practices and advanced technology help to address the different types of pollutants. Freshwater Pollution and Aquatic Ecosystems: Environmental Impact and Sustainable Management considers the need for sustainable, efficient, and cost-effective tools and technologies to assess, monitor, and properly manage the increasing issues of aquatic pollution. It provides detailed accounts of the phenomena and mechanisms related to aquatic pollution and highlights the problems and threats associated with pollution contamination in freshwater. It provides useful insight into the sustainable and advanced pollution remediation technology adopted by different countries for the monitoring, assessment, and sustainable management of pollution. The chapters in the volume evaluate the sources of harmful pollutants, which include industrial effluents, sewage, and runoff from agricultural industries, which result in toxic microbes, organic waste, oils, and high load of nutrients. Unsustainable management practices of domestic sewage and indiscriminate use of chemical pesticides lead to the technological disturbance of aquatic biota. In addition to harming aquatic biota, these pollutants find their way into the human body through inhalation, ingestion, or absorption and finally tend to bio-accumulate in trophic levels of the food chain, which poses a major risk to human beings. This book will be a valuable resource for ecologists, environmentalists, scientists, and many others for their work in understanding and management of aquatic pollutants in freshwater biospheres. |

| freshwater algae identification and use as bioindicators: Riverine Ecosystem Management Jan Sendzimir, Stefan Schmutz, 2020-10-08 This open access book surveys the frontier of scientific river research and provides examples to guide management towards a sustainable future of riverine ecosystems. Principal structures and functions of the biogeosphere of rivers are explained; key threats are identified, and effective solutions for restoration and mitigation are provided.Rivers are among the most threatened ecosystems of the world. They increasingly suffer from pollution, water abstraction, river channelisation and damming. Fundamental knowledge of ecosystem structure and function is necessary to understand how human acitivities interfere with natural processes and which interventions are feasible to rectify this.Modern water legislation strives for sustainable water resource management and protection of important habitats and species. However, decision makers would benefit from more profound understanding of ecosystem degradation processes and of innovative methodologies and tools for efficient mitigation and restoration. The book provides best-practice examples of sustainable river management from on-site studies, European-wide analyses and case studies from other parts of the world. This book will be of interest to researchers in the field of aquatic ecology, river system functioning, conservation and restoration, to postgraduate students, to institutions involved in water management, and to water related industries.

| freshwater algae identification and use as bioindicators: Freshwater Fungi E. B. Gareth Jones, Kevin D Hyde, Ka-Lai Pang, 2014-08-27 The available literature on freshwater fungi is limited. Over the subsequent years a considerable volume of scientific papers have appeared scattered throughout numerous journals. There is therefore no recent synthesis of the subject and this is the objective of the proposed book. Freshwater habitats are rich in fungi with some 3,000 described species, most of papers focussing on their identification, substrata they grow on and world distribution. However, these fungi play an important role in the freshwater ecosystem, and are primarily involved in the breakdown of leaf litter contributing food for detritus feeders. Our book will bring together a wide range of acclaimed mycologists to review recent developments on the biology and ecology of freshwater fungi, particularly their molecular phylogeny, biodiversity, causative diseases of freshwater amphibians, fishes and invertebrate animals, decomposition of leaf litter, stream pollution and their potential role in bioremediation. |

| freshwater algae identification and use as bioindicators: Cyanobacterial Harmful Algal Blooms H. Kenneth Hudnell, 2016-04-01 Cyanobacteria are single-celled organisms that live in fresh, brackish, and marine water. They use sunlight to make their own food. In warm, nutrient-rich environments, microscopic cyanobacteria can grow quickly, creating blooms that spread across the water s surface and may become visible. Because of the color, texture, and location of these blooms, the common name for cyanobacteria is blue-green algae. However, cyanobacteria are related more closely to bacteria than to algae. Cyanobacteria are found worldwide, from Brazil to China, Australia to the United States. In warmer climates, these organisms can grow year-round. Scientists have called cyanobacteria the origin of plants, and have credited cyanobacteria with providing nitrogen fertilizer for rice and beans. But blooms of cyanobacteria are not always helpful. When these blooms become harmful to the environment, animals, and humans, scientists call them cyanobacterial harmful algal blooms (CyanoHABs). Freshwater CyanoHABs can use up the oxygen and block the sunlight that other organisms need to live. They also can produce powerful toxins that affect the brain and liver of animals and humans. Because of concerns about CyanoHABs, which can grow in drinking water and recreational water, the U.S. Environmental Protection Agency (EPA) has added cyanobacteria to its Drinking Water Contaminant Candidate List. This list identifies organisms and toxins that EPA considers to be priorities for investigation. Reports of poisonings associated with CyanoHABs date back to the late 1800s. Anecdotal evidence and data from laboratory animal research suggest that cyanobacterial toxins can cause a range of adverse human health effects, yet few studies have explored the links between CyanoHABs and human health. Humans can be exposed to cyanobacterial toxins by drinking water that contains the toxins, swimming in water that contains high concentrations of cyanobacterial cells, or breathing air that contains cyanobacterial cells or toxins (while watering a lawn with contaminated water, for example). Health effects associated with exposure to high concentrations of cyanobacterial toxins include: stomach and intestinal illness; trouble breathing; allergic responses; skin irritation; liver damage; and neurotoxic reactions, such as tingling fingers and toes. Scientists are exploring the human health effects associated with long-term exposure to low levels of cyanobacterial toxins. Some studies have suggested that such exposure could be associated with chronic illnesses, such as liver cancer and digestive-system cancer. This monograph contains the proceedings of the International Symposium on Cyanobacterial Harmful Algal Blooms held in Research Triangle Park, NC, September 6-10, 2005. The symposium was held to help meet the mandates of the Harmful Algal Bloom and Hypoxia Research and Control Act, as reauthorized and expanded in December 2004. The monograph will be presented to Congress by an interagency task force. The monograph includes: 1) A synopsis which proposes a National Research Plan for Cyanobacteria and their Toxins; 2) Six workgroup reports that identify and prioritize research needs; 3) Twenty-five invited speaker papers that describe the state of the science; 4) Forty poster abstracts that describe novel research. |
