Download or read book Estuaries written by Julian R. Crane and published by . This book was released on 2009 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: Estuaries are productive ecosystems of high ecological value. They are important habitats for various species and those of highest value are protected by national and international conventions. This book highlights possible pollution impacts in a protected estuarine ecosystem, Amvrakikos Gulf, considered as one of the most important wetlands in Greece. In addition, the Changjiang (Yangtze) River is known to contribute significantly to the ecosystems of the Changjiang River estuary and adjacent waters. In this book, some long-term data of freshwater discharge, sediment load, nutrient concentrations and compositions in the river and estuary waters are presented, as well as the long-term response of the ecosystem in the estuary. Moreover, the literature on modern estuarine diatoms from Argentina is revised in order to synthesise the available ecological information and to detect possible modern analogues for Quaternary diatom assemblages. The authors also discuss negative or inverse estuaries, those where seawater is concentrated by the removal of fresh water, in the Northern Gulf of California. The challenges facing the sustainable management of temporarily open/closed estuaries (TOCEs) is addressed as well, critical in some cases because their ecological integrity, biodiversity and nursery function have already been compromised.

Silambarasan and published by Independent Author. This book was released on 2023-02-24 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book titled "Diversity and Distribution of Phytoplankton Community Structure Vis a Vis Chlorophyll Pigments in True Estuarine Ecosystem" authored by A. Silambarasan presents a comprehensive study of phytoplankton diversity and community structure in estuarine ecosystems. The book explores the relationship between chlorophyll pigments and phytoplankton assemblages, and how they impact the ecological balance of estuarine systems. The author conducted an extensive survey of phytoplankton and chlorophyll pigments in three different estuaries, and the data collected was analyzed to evaluate the diversity, distribution, and abundance of phytoplankton species. The book highlights the significance of phytoplankton as a key component of aquatic ecosystems and their impact on the food chain. It also sheds light on the various factors affecting the distribution of phytoplankton, including temperature, salinity, and nutrient availability. The book also discusses the ecological implications of changing phytoplankton populations and the impact on the ecosystem and biodiversity. Overall, the book is a valuable resource for students, researchers, and environmentalists who are interested in understanding the dynamics of estuarine ecosystems and the role of phytoplankton in maintaining the ecological balance.

Download or read book Temporarily Open closed Estuaries in South Africa written by R. Perissinotto and published by . This book was released on 2010 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: South African temporarily open/closed estuaries (TOCEs) and similar systems along the coastlines of other regions of the world, especially Australia, are amongst the most productive aquatic ecosystems. They shift seasonally from mostly open mouth states during rainy seasons to mostly closed mouth states during the dry part of the year. This allows a whole range of juvenile forms of estuarine-dependent and estuarine-associated marine species to be recruited inside their sheltered and productive reaches, where they complete their growth to maturity. This book covers topics such as the structure and function of open/closed estuaries in South Africa, as well as outlining the future management decisions that need to be made in order to ensure the longevity of these productive ecosystems.

Download or read book Phytoplankton Community Structure Response to Groundwater borne Nutrients in the Inland Bays DE written by Daniel M. Torre and published by . This book was released on 2016 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: We conducted a series of experiments, coupling seepage meters directly to phytoplankton enclosure experiments to determine the impacts of groundwater-borne nutrients on biomass and response in community structure of phytoplankton. To assess the impacts of groundwater-borne nutrients, we measured chlorophyll a concentrations as a proxy for overall biomass and used genetic sequencing techniques to characterize the phytoplankton community structure. Groundwater carried a high N load to the estuary with NO3- up to 295 μmol/L, and NH4 + up to 55 μmol/L. As a result treatment mesocosms had NO 3- concentrations up to 55.5 μmol/L and NH 4+ up to 4.0 μmol/L, while control mesocosms received filtered seawater, and were thus relatively low in nutrients (24.2 μmol/L NO3- and ∼2 μmol/L NH4 +). In June the highest chlorophyll a concentrations occurred after 3.5 days, with significant differences between control mesocosms (4.3±0.2 mg/L), groundwater amended mesocosms (7.0±0.6 mg/L), and mesocosms receiving groundwater across the sediment-water interface (10.9±0.2 mg/L). In August, biomass peaked after 3 days and showed larger variation across treatment groups with groundwater amended mesocosms reaching significantly higher values (36.6±2.0 mg/L) than mesocosms receiving groundwater across the sediment-water interface (18.7±4.8 mg/L), which showed significantly different values than both controls and phosphate amended mesocosms (11.9±0.7 and 9.9±0.2 mg/L respectively). Community gene sequence data showed that species assemblage was also impacted by availability of nutrients, with significant differences in community structure for mesocosms receiving nutrients vs control mesocosms in both June and August experiments. Several harmful algal species also proliferated in high nutrient treatments, including Cylindrotheca closterium, Karlodinium veneficum, Nitzschia ovalis, and Heterocapsa sp. Our study demonstrates the importance groundwater-borne nutrients play in structuring the phytoplankton community, and the potential impacts of nutrient loading through groundwater transport. More research is needed to further identify spatial and temporal differences in groundwater-borne nutrient discharge and response of phytoplankton community structure.
Download or read book Plankton written by Iain Suthers and published by CSIRO PUBLISHING. This book was released on 2019-04-01 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: Healthy waterways and oceans are essential for our increasingly urbanised world. Yet monitoring water quality in aquatic environments is a challenge, as it varies from hour to hour due to stormwater and currents. Being at the base of the aquatic food web and present in huge numbers, plankton are strongly influenced by changes in environment and provide an indication of water quality integrated over days and weeks. Plankton are the aquatic version of a canary in a coal mine. They are also vital for our existence, providing not only food for fish, seabirds, seals and sharks, but producing oxygen, cycling nutrients, processing pollutants, and removing carbon dioxide from our atmosphere. This Second Edition of Plankton is a fully updated introduction to the biology, ecology and identification of plankton and their use in monitoring water quality. It includes expanded, illustrated descriptions of all major groups of freshwater, coastal and marine phytoplankton and zooplankton and a new chapter on teaching science using plankton. Best practice methods for plankton sampling and monitoring programs are presented using case studies, along with explanations of how to analyse and interpret sampling data. Plankton is an invaluable reference for teachers and students, environmental managers, ecologists, estuary and catchment management committees, and coastal engineers.

This book was released on 2008-06-05 with total page 880 pages. Available in PDF, EPUB and Kindle. Book excerpt: The proliferation of harmful phytoplankton in marine ecosystems can cause massive fish kills, contaminate seafood with toxins, impact local and regional economies and dramatically affect ecological balance. Real-time observations are essential for effective short-term operational forecasting, but observation and modelling systems are still being developed. This volume provides guidance for developing real-time and near real-time sensing systems for observing and predicting plankton dynamics, including harmful algal blooms, in coastal waters. The underlying theory is explained and current trends in research and monitoring are discussed.Topics covered include: coastal ecosystems and dynamics of harmful algal blooms; theory and practical applications of in situ and remotely sensed optical detection of microalgal distributions and composition; theory and practical applications of in situ biological and chemical sensors for targeted species and toxin detection; integrated observing systems and platforms for detection; diagnostic and predictive modelling of ecosystems and harmful algal blooms, including data assimilation techniques; observational needs for the public and government; and future directions for research and operations.
