This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The "Degradation of Phytoplankton and Zooplankton Populations" Beneficial Use Impairment (BUI 13) for the Bay of Quinte Area of Concern (AOC) has been designated as impaired since the site was listed under the Canada - United States Great Lakes Water Quality Agreement. This analysis provides a final assessment by Fisheries and Oceans Canada, based on the 47 years of sampling for Project Quinte from 1972 - 2018. This assessment provides a refined list of 10 metrics (reduced from the possible 26 proposed in 2017) for phytoplankton, zooplankton and microbial populations that can be used to track improvements in the system. This assessment finds that while there have been some long-term improvements in the planktonic communities indices, food web function and trophic transfer continue to be significantly impaired"--Abstract.

Fitzpatrick and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Phytoplankton, zooplankton and microbial communities of the Canadian waters of the Detroit River were sampled during May, July, September and November of 2019 in order to provide guidance to the Remedial Action Plan regarding the status of Beneficial Use Impairment 13: Degradation of Phytoplankton and Zooplankton Populations. Eight sites between Lake St Clair and Amherstburg were sampled capturing both upstream - downstream as well as nearshore - offshore gradients. Biomass of each of the components including: phytoplankton, autotrophic picoplankton, heterotrophic nanoflagellates, ciliates, rotifers and zooplankton, was generally low with zooplankton biomass attenuating significantly downstream. Phytoplankton biomass was observed to be significantly higher nearshore than offshore. Primary (phytoplankton) productivity was moderately high, given the low phytoplankton biomass, and demonstrates the river supports viable phytoplankton assemblages. In general, the observed differences in the planktonic communities occurring within the Area of Concern could be attributed directly to riverine ecology. Likewise, our assessment of the organic carbon pool showed that, despite the low overall amount (50 - 100 mg C m−3 on average), the food web was still predominantly autotrophic and not bound up in heterotrophic microbes. Our survey did not find any evidence of anthropogenic impairment of the phytoplankton, zooplankton and microbial loop populations of the Detroit River"--Abstract, page vii.

It illustrates numerous applications of Ecological Informatics for stream systems, river systems, freshwater lakes and marine systems as well as image recognition at micro and macro scale. Case studies focus on applications of artificial neural networks, genetic algorithms, fuzzy logic and adaptive agents to current ecological management issues such as toxic algal blooms, eutrophication, habitat degradation, conservation of biodiversity and sustainable fishery.
Download or read book Shallow Lakes 95 written by Lech Kufel and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: Shallow lakes differ from deep ones in many aspects of nutrient dynamics, biotic structure and interactions of various trophic levels. Though very common in European lowlands, shallow lakes attract inadequate attention from research teams. This book aims at filling gaps in our knowledge of the processes which take place in non-stratified lakes. It contains proceedings from the international conference `Shallow Lakes *95' held in Mikolajki, Poland, on 20-26 August 1995. In more than 50 original papers up-to-date views on eutrophication, degradation and recovery of shallow lakes are presented. The first four sections of the book (Nutrient fluxes, Biotic structure, Trophic interactions and Whole lake studies) deal with theoretical aspects of lake functioning while the fifth (Biomanipulation, restoration and management) is devoted to practical measures undertaken to improve water quality in shallow lakes. The book is therefore addressed to university biologists and ecologists and PhD students, as well as to managers involved in restoration of shallow lakes.

Download or read book Integration of Ecosystem Theories A Pattern written by Sven Erik Jørgensen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book presents an integration of existing ecosystem theories in such a comprehensive way as to enable a full ecological and theoretical pattern to be presented. It shows that ecosystems and their reactions may be understood, provided that all basic systems ecology is applied to different aspects of the properties of ecosystems. Since the publication of the previous two editions of this book, ongoing research and discussions on an international scale have greatly clarified and enhanced this pattern. This progress is presented as Chapter 16 in this new, third edition. It is shown that the integrated ecosystem theory presented can be applied to explain various ecological observations and rules. Audience: Researchers and decision makers whose work involves the study of ecosystems and ecology. This book is also recommended for use in graduate courses.
Download or read book Food Web Management written by James F. Kitchell and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 561 pages. Available in PDF, EPUB and Kindle. Book excerpt: This series is dedicated to serving the growing community of scholars and practitioners concerned with the principles and applications of environ mental management. Each volume is a thorough treatment of a specific topic of importance for proper management practices. A fundamental objective of these books is to help the reader discern and implement man's stewardship of our environment and the world's renewable re sources. For we must strive to understand the relationship between man and nature, act to bring harmony to it, and nurture an environment that is both stable and productive. These objectives have often eluded us because the pursuit of other individual and societal goals has diverted us from a course of living in balance with the environment. At times, therefore, the environmental manager may have to exert restrictive control, which is usually best applied to man, not nature. Attempts to alter or harness nature have often failed or backfired, as exemplified by the results of imprudent use of herbicides, fertilizers, water, and other agents. Each book in this series will shed light on the fundamental and applied aspects of environmental management. It is hoped that each will help solve a practical and serious environmental problem.

Download or read book Phytopharmacy written by Sarah E. Edwards and published by John Wiley & Sons. This book was released on 2015-02-17 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: Healthcare professionals, including doctors, pharmacists and nurses, are often confronted with patients who use over-the-counter (OTC) herbal medicinal products and food supplements. While taking responsibility for one’s own health and treatment options is encouraged, many patients use these products based on limited (and sometimes inaccurate) information from non-scientific sources, such as the popular press and internet. There is a clear need to offer balanced, well-informed advice to patients, yet a number of studies have shown that, generally, conventionally trained health practitioners consider their knowledge about herbal medicinal products and supplements to be weak. Phytopharmacy fills this knowledge gap, and is intended for use by the busy pharmacist, nurse, or doctor, as well as the ‘expert patient’ and students of pharmacy and herbal medicine. It presents clear, practical and concise monographs on over a hundred popular herbal medicines and plant-based food supplements. Information provided in each monograph includes: • Indications • Summary and appraisal of clinical and pre-clinical evidence • Potential interactions • Contraindications • Possible adverse effects An overview of the current regulatory framework is also outlined, notably the EU Traditional Herbal Medicinal Products Directive. This stipulates that only licensed products or registered traditional herbal medicinal products (THRs), which have assured quality and safety, can now legally be sold OTC. Monographs are included of most of the major herbal ingredients found in THRs, and also some plant-based food supplements, which while not strictly medicines, may also have the potential to exert a physiological effect.
