Available in PDF, EPUB and Kindle. Book excerpt: The different measurements of environmental factors or of phytoplankton populations, obtained in different points of a volume of water, can never be considered as random samples of an uniform statistical universe. It is more appropriate to study distributions as dependent of position in space and, as manifestations of an 'organization'. The density of one given species in a small volume of water is not only a function of local environmental properties, but also depends on the concentration of the same species in some neighboring area. Diffusivity and water turbulence is very important, as are the gradients and generated flows. Patches of strongly stratified water, poor in nutrients is another unit of reference. A careful consideration of the distribution of phytoplankton advises a change in the order of importance given to the different factors. Salinity and temperature have been often considered as very important factors in plankton distribution, but from recent evidence turbulence and nutrient contents are, besides light, the chief factors in explaining phytoplankton populations. It was discovered that not only total amount of plant pigments, but also relative concentration of pigments could be meaningful. Pigment ratios could be substituted, in the practice, by ratios between absorbancies at given wavelengths of the pigment extracts. Thus, progress in plant physiology emphasizes the idea that the diversity of pigments is an expression of properties of the photosynthetizing apparatus, and that the said pigment ratios, besides any taxonomical interpretation, have implications of true ecological relevance concerning the degree of evolution or the stage of succession.

Book excerpt: Written by an outstanding group of contributors, this book examines the function and structure of coastal lagoonal ecosystems and the natural and anthropogenic drivers of change that affect them, most notably nutrient over-enrichment from coastal watersheds and airsheds. The contributors target the susceptibility of coastal lagoons to eutrophication, the indicators of eutrophic conditions, the influences of natural factors such as major storms and other climate effects, and the resulting biotic and ecosystem impairments that have developed. The book compares biogeochemical and ecological response to nutrient enrichment and other pollutants in lagoonal estuaries to those in other estuarine types.

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.

Book excerpt: This condensed volume summarizes updated knowledge on the warm-monomictic subtropical Lake Kinneret, including its geophysical setting, the dynamics of physical, chemical and biological processes and the major natural and anthropogenic factors that affect this unique aquatic ecosystem. This work expands on a previous monograph on Lake Kinneret published in 1978 and capitalizes on the outcome of more than 40 years of research and monitoring activities. These were intensively integrated with lake management aimed at sustainable use for supply of drinking water, tourism, recreation and fishery. The book chapters are aimed at the limnological community, aquatic ecologists, managers of aquatic ecosystems and other professionals. It presents the geographic and geological setting, the meteorology and hydrology of the region, continues with various aspects of the pelagic and the littoral systems. Finally, the last section of the book addresses lake management, demonstrating how the accumulated knowledge was applied in order to manage this important source of freshwater. The section on the pelagic system comprises the heart of the book, addressing the major physical processes, external and internal loading, the pelagic communities (from bacteria to fish), physiological processes and the major biogeochemical cycles in the lake.

This book was released on 2010-08-23 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Measurements of variable chlorophyll fluorescence have revolutionised global research of photosynthetic bacteria, algae and plants and in turn assessment of the status of aquatic ecosystems, a success that has partly been facilitated by the widespread commercialisation of a suite of chlorophyll fluorometers designed for almost every application in lakes, rivers and oceans. Numerous publications have been produced as researchers and assessors have simultaneously sought to optimise protocols and practices for key organisms or water bodies; however, such parallel efforts have led to difficulties in reconciling processes and patterns across the aquatic sciences. This book follows on from the first international conference on “chlorophyll fluorescence in the aquatic sciences” (AQUAFLUO 2007): to bridge the gaps between the concept, measurement and application of chlorophyll fluorescence through the synthesis and integration of current knowledge from leading researchers and assessors as well as instrument manufacturers.
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.
