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.

This book was released on 2016 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This report collects all available plankton community data for the Niagara River Area of Concern (AOC) designated requires further assessment for the Beneficial Use Impairment (BUI 13): "degradation of phytoplankton and zooplankton populations". The Niagara River connecting channel, though it joins well-studied Lake Erie and Lake Ontario is data-poor, with no active plankton sampling programs. A single season of sampling in 2014 took place monthly from June-Oct for water quality, zooplankton and phytoplankton composition and density. Oligotrophic conditions persisted throughout the season and plankton densities were extremely low, though this was expected in a high-flow system such as the Niagara River. The residence time for plankton in the Niagara River is only 11-28 hours, but could be much longer if plankton are entrained in the hydroelectric reservoirs. Given the results of this survey, no impairment of plankton populations is indicated"--Abstract, p. iv.

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.

This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report collects all available data from past literature and unpublished DFO surveys, in three sub-reports, on two Areas of Concern (AOC) designated requires further assessment for the Beneficial Use Impairment (BUI 13): "degradation of phytoplankton and zooplankton populations". Toronto Region and Thunder Bay AOC are data-poor, with no active plankton sampling programs. A single 2013 Toronto survey coincided with a large upwelling, with plankton densities lower than expected within Toronto Harbour, matching results from past surveys. MOECC Index archived plankton samples were counted, but were insufficient to evaluate BUI 13 due to high variability and sparse sampling. A minimum six samples annually are required to determine species composition. Plankton data are documented for Thunder Bay and Superior, but no samples were available for impacted areas near the Kaministiquia River and inner Thunder Bay Harbour.

Available in PDF, EPUB and Kindle. Book excerpt: Phytoplankton responses to human impact at different scales provides a state-of-the-art review of changes in the phytoplankton assemblages determined by human alterations of lakes and rivers. A wide spectrum of case studies describe the effects due to eutrophication and climate change, as well as other impacts connected with watershed management, hydrological alterations and introduction of non-indigenous species. The volume also includes two wide reviews on planktonic coccoid green algae and planktic heterocytous cyanobacteria. This book is addressed to ecologists and scientists involved in phytoplankton ecology and taxonomy. Many case studies provide a sound scientific basis of knowledge for a wise management of water bodies. Previously published in Hydrobiologia, vol. 698, 2012
Download or read book Changing Plankton Communities Causes Effects and Consequences written by Kristian Spilling and published by Frontiers Media SA. This book was released on 2019-10-04 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine ecosystems are changing at an unprecedented rate. In addition to the direct effects of e.g. warming surface temperatures, the environmental changes also cause shifts in plankton communities. Plankton makes up the base of the marine food web and plays a pivotal role in global biogeochemical cycles. Any shifts in the plankton community composition could have drastic consequences for marine ecosystem functioning. This Research Topic focuses on causes, effects and consequences of such shifts in the plankton community structure.

Available in PDF, EPUB and Kindle. Book excerpt: This book aims at providing students and researchers an advanced integrative overview on zooplankton ecology, covering marine and freshwater organisms, from microscopic phagotrophic protists, to macro-jellyfishes and active fish larvae. The first book section addresses zooplanktonic organisms and processes, the second section is devoted to zooplankton spatial and temporal distribution patterns and trophic dynamics, and the final section is dedicated to emergent methodological approaches (e.g., omics). Book chapters include comprehensive synthesis, observational and manipulative studies, and sediment-based analysis, a vibrant imprint of benthic-pelagic coupling and ecosystem connectivity. Most chapters also address the impacts of anticipated environmental changes (e.g., warming, acidification).

Download or read book Zooplankton Community Analysis written by W.M. Jr. Lewis and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 171 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is based on the premise that the study of ecological communities should be a composite analysis of system properties (community structure, community energetics) and population properties (life history patterns, adaptive strategies) backed by a thorough understanding of the physical chemical environment. Too frequently community ecology takes a much narrower focus. This may partly be the result of perceived antagonisms between schools of thought in ecology. Despite their rather separate origins, the multiple theoretical and methodological tools that now exist must be applied synthetically to real communities if the progress of the past two decades is to continue into the next two. This book has a case history format, which increases the opportunity for detailed analysis, although I have attempted to maintain the general per spective of a community ecologist and to draw extensively from the literature whenever it seems profitable to do so. The case history data are for Lake Lanao, a large tropical lake. The main zooplankton data base used in the analysis is entirely original and unpublished, although the detailed support ing data on the physical-chemical environment and the phytoplankton com munity have been presented in numerous journal articles and are thus abstracted or used selectively to meet the needs of zooplankton community analysis.
