Download or read book Chlorophyll a Fluorescence in Aquatic Sciences Methods and Applications written by David J. Suggett and published by Springer Science & Business Media. 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.

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.

Download or read book Composition of Phytoplankton Communities and Their Contribution to Secondary Productivity in Carolina Bays on the Savannah River Plant written by and published by . This book was released on 1991 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: The overall goal of the this three year project is to determine the importance of phytoplankton (microscopic algae) as a component of the food chain base in SRS cardine bays. To summarize specific year three results: Total phytoplankton abundance in Flamingo bay was greatest during early spring 1989, declined during spring and summer, but increased again during early fall. Most of this phytoplankton density was composed of genus Chlamydomonas sp. Ellenton bay demonstrated a similar decline in phytoplankton numbers during midspring 1989, but increased in density during midsummer. As observed in Flamingo bay, much of this variation was due to changes in Chlamydomonas sp. numbers. In Flamingo bay the blue-green alga Anabaena sp. was low in concentration throughout the 1989 flooded season until August, however the diatom Pinnularia sp. displayed a pattern of abundance similar to Chlamydomonas sp. In Ellenton bay Pinnularia sp. peaked during early summer and Anabaena sp. reached highest densities in late spring. For zooplankton in Flamingo bay, the calanoid copepods were higher in early and late spring, similar to the cyclopoid copepods. Cladocera in Ellenton bay were highest in numbers during May 1989, while cladocera in Flamingo bay displayed patterns similar to Flamingo bay cyclopoid copepods. Laboratory experiments exposing Chlamydomonas sp. cultures to known mixtures of 13C-CO2 and 12C-CO2 seem to indicate that some isotope preference may exist during photosynthesis, however these results have not been analyzed statistically yet. Phytoplankton samples collected for Flamingo bay indicated that a seasonal change in isotope ratios may be occurring in algae tissues, however further analyses are being conducted to determine whether this may also be due to species shifts. 3 refs., 14 figs.
Download or read book Ocean Biogeochemistry written by Michael J.R. Fasham and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oceans account for 50% of the anthropogenic CO2 released into the atmosphere. During the past 15 years an international programme, the Joint Global Ocean Flux Study (JGOFS), has been studying the ocean carbon cycle to quantify and model the biological and physical processes whereby CO2 is pumped from the ocean's surface to the depths of the ocean, where it can remain for hundreds of years. This project is one of the largest multi-disciplinary studies of the oceans ever carried out and this book synthesises the results. It covers all aspects of the topic ranging from air-sea exchange with CO2, the role of physical mixing, the uptake of CO2 by marine algae, the fluxes of carbon and nitrogen through the marine food chain to the subsequent export of carbon to the depths of the ocean. Special emphasis is laid on predicting future climatic change.

Available in PDF, EPUB and Kindle. Book excerpt: Identifying Marine Diatoms and Dinoflagellates is the second identification manual created from the literature developed for the Advanced International Phytoplankton Course. This version, enlarged and modified from the earlier literature, deals with the identification of marine diatoms and dinoflagellates. The data and references presented here should allow the researcher to pursue the question of valid species and how they can be verified. This volume comprises three chapters, beginning with an introductory chapter discussing the subject's historical background. The next chapter focuses on marine diatoms, providing an introduction that describes their general characteristics, life cycles, morphology and terminology, and classification. It is followed by a discussion of genera represented in marine plankton, a description of taxa, and methodology. The third and final chapter focuses on dinoflagellates, beginning with an introduction that describes their general characteristics and eukaryotic unicells. The discussion continues with terminology and morphology, identification of species, techniques for preparation of dinoflagellates for identification, common dinoflagellate synonyms, and an index of dinoflagellate taxa. This book will be of interest to practitioners in the fields of biology, zoology, and environmental protection.
Download or read book Photosynthesis in Algae Biochemical and Physiological Mechanisms written by Anthony W.D. Larkum and published by Springer Nature. This book was released on 2020-06-03 with total page 534 pages. Available in PDF, EPUB and Kindle. Book excerpt: Algae, including cyanobacteria, are in the spotlight today for a number of reasons; firstly it has become abundantly clear over recent years that algae have been neglected in terms of basic research and that knowledge gap is being rapidly closed with the establishment of some surprising discoveries, such as the presence of Near-Infra-Red-Absorbing cyanobacteria and a wealth of natural products; secondly molecular approaches have provided a wealth of approaches to genetically modify algae and produce value-added products; thirdly it has become clear just how important, marine phytoplankton is to global carbon capture and the production of food globally; and fourthly, it has also become clear that algae present unparalleled opportunities to generate biofuels in a sustainable and non-polluting way. This volume presents 15 chapters by world experts on their subjects, ranging from reviews of algal diversity and genetics to in-depth reviews of special algal groups such as diatoms (which account for over 30% of marine carbon capture). Other chapters chart the ways in which this carbon capture occurs or how there are a multiplicity of ways in which algae intercept sun light and deploy this energy for carbon capture. A fascinating aspect here is the way in which sun light is harvested. A special chapter is devoted to the very recent and exciting possibility that algae use coherent light energy transformation to enhance the efficiency of light capture, an aspect of quantum physics that has implications for future developments at several levels and a variety of industries. Just how and why algae use Chlorophyll a as the major light capture pigment is discussed in several chapters. However, attention is also given to those cyanobacteria, which have been found to use the special Near-Infra Red absorbing chlorophylls mentioned above. And attention is also given to those algae that employ phycobiliproteins to fill in the “green window”, i.e., the spectral region from 400 – 650 nm, which is not efficiently covered by chlorophyll and carotenoid pigments. Photoinhibition and photoprotection is the subject area of several chapters and one which it is essential to understand a we work towards greater efficiency of algal photosynthesis. A final chapter is devoted to understanding the molecular basis for coral bleaching, a much-neglected area that is essential in trying to come up with solutions to this very worrying phenomenon, caused by global warming and ocean acidification. This is a book for research scientists, environmentalists, planners in a range of areas including those of marine resources, nutrient control and pollution of water bodies and that growing body of concerned citizens interested in controlling carbon emissions and global warming. Special attention has been given to generating a set of articles that will be read by university students, informed laymen and all those whose wish to understand the rapid changes that have come about in our knowledge of algae over the past decade.
Download or read book Ocean Acidification written by National Research Council and published by National Academies Press. This book was released on 2010-09-14 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ocean has absorbed a significant portion of all human-made carbon dioxide emissions. This benefits human society by moderating the rate of climate change, but also causes unprecedented changes to ocean chemistry. Carbon dioxide taken up by the ocean decreases the pH of the water and leads to a suite of chemical changes collectively known as ocean acidification. The long term consequences of ocean acidification are not known, but are expected to result in changes to many ecosystems and the services they provide to society. Ocean Acidification: A National Strategy to Meet the Challenges of a Changing Ocean reviews the current state of knowledge, explores gaps in understanding, and identifies several key findings. Like climate change, ocean acidification is a growing global problem that will intensify with continued CO2 emissions and has the potential to change marine ecosystems and affect benefits to society. The federal government has taken positive initial steps by developing a national ocean acidification program, but more information is needed to fully understand and address the threat that ocean acidification may pose to marine ecosystems and the services they provide. In addition, a global observation network of chemical and biological sensors is needed to monitor changes in ocean conditions attributable to acidification.

Download or read book Response of the Phytoplankton Community of Eurotrophic Medical Lake Washington to Phosphorus Inactivation by Aluminum Sulfate written by Michael Alan Beckwith and published by . This book was released on 1978 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: "A lake restoration project involving surface and hypolim-netic application of 936 metric tons of liquid aluminum sulfate (alum) was carried out on Medical Lake, Washington in the summer of 1977. Previous investigation has shown that the eutrophic condition of the lake is primarily the result of internal phosphorus cycling (Bauman and Soltero, In press). Goals of the restoration project were to disrupt the phosphorus cycling and reduce phosphorus concentrations, to reduce phytoplankton production and eliminate blue-green algae blooms, to reduce ammonia concentrations and improve dissolved oxygen levels in the hypolimnion, and to improve water clarity. Preliminary results indicate that mean concentrations of total and total soluble phosphate in the water column just after spring overturn in 1978 were approximately 20 percent of those concentrations existing in the spring of 1977. Orthophosphate concentrations at spring overturn in 1978 have also been reduced to approximately 5 percent of spring 1977 levels. Water clarity improved markedly during alum application due to removal of algal cells and particulate matter by the aluminum hydroxide floc formed when alum was added. Following treatment, reduced phytoplankton standing crops as measured by cell volume and chlorophyll a concentrations also contributed to increased water clarity. A shift in the species composition of the phytoplankton community occurred. A community dominated by Cyanophyceae existed before treatment while a more diverse community of Chlorophyceae, cryptophyceae, and Chrysophyceae existed tollowing treatment. The nutrient limiting to phytoplankton growth changed from nitrogen to phosphorus following treatment as indicated by algal assay. Yields of Selenastrum capricornutum Printz in the controls also suggested that the potential for algal growth in Medical Lake was high prior to alum treatment but only moderate following treatment"--Document.
