Available in PDF, EPUB and Kindle. Book excerpt: Since its discovery Antarctica has held a deep fascination for biologists. Extreme environmental conditions, seasonality and isolation have lead to some of the most striking examples of natural selection and adaptation on Earth. Paradoxically, some of these adaptations may pose constraints on the ability of the Antarctic biota to respond to climate change. Parts of Antarctica are showing some of the largest changes in temperature and other environmental conditions in the world. In this volume, published in association with the Royal Society, leading polar scientists present a synthesis of the latest research on the biological systems in Antarctica, covering organisms from microbes to vertebrate higher predators. This book comes at a time when new technologies and approaches allow the implications of climate change and other direct human impacts on Antarctica to be viewed at a range of scales; across entire regions, whole ecosystems and down to the level of species and variation within their genomes. Chapters address both Antarctic terrestrial and marine ecosystems, and the scientific and management challenges of the future are explored.
Download or read book Photosynthesis Mechanisms and Effects written by Gyözö Garab and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 4476 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photosynthesis is a process on which virtually all life on Earth depends. To answer the basic questions at all levels of complexity, from molecules to ecosystems, and to establish correlations and interactions between these levels, photosynthesis research - perhaps more than any other discipline in biology - requires a multidisciplinary approach. Congresses probably provide the only forums where progress throughout the whole field can be overviewed. The Congress proceedings give faithful pictures of recent advances in photosynthesis research and outline trends and perspectives in all areas, ranging from molecular events to aspects of photosynthesis on the global scale. The Proceedings Book, a set of 4 (or 5) volumes, is traditionally highly recognized and intensely quoted in the literature, and is found on the shelves of most senior scientists in the field and in all major libraries.

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.

Download or read book Non Photochemical Quenching and Energy Dissipation in Plants Algae and Cyanobacteria written by Barbara Demmig-Adams and published by Springer. This book was released on 2014-11-22 with total page 672 pages. Available in PDF, EPUB and Kindle. Book excerpt: Harnessing the sun’s energy via photosynthesis is at the core of sustainable production of food, fuel, and materials by plants, algae, and cyanobacteria. Photosynthesis depends on photoprotection against intense sunlight, starting with the safe removal of excess excitation energy from the light-harvesting system, which can be quickly and non-destructively assessed via non-photochemical quenching of chlorophyll fluorescence (NPQ). By placing NPQ into the context of whole-organism function, this book aims to contribute towards identification of plant and algal lines with superior stress resistance and productivity. By addressing agreements and open questions concerning photoprotection’s molecular mechanisms, this book contributes towards development of artificial photosynthetic systems. A comprehensive picture –from single molecules to organisms in ecosystems, and from leading expert’s views to practical information for non-specialists on NPQ measurement and terminology – is presented.
Download or read book Algal Photosynthesis written by Richard Geider and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: The algae are a diverse group of organisms with forms that range in size from less than a micron in diameter to over ten meters in length. Small {laquo} 1 JLm diam) unicellular forms dominate the open waters of the oceans and large lakes. Large multicellular forms often form a large component of the autotrophic biomass of shallow waters at the periphery of lakes and oceans but have also been found on seamounts in clear open ocean waters at depths up to several hundred meters (Littler and Littler, 1985). Phytoplankton in the sea probably account for more than 50% of global photosynthesis, although there is considerable uncertainty about this estimate. In addition, many symbiotic associations between unicellu lar algae and heterotrophic or autotrophic organisms have been identi fied, and algae can be found in a diverse range of terrestrial environ ments, ranging from polar to desert regions. The most important common biochemical attribute that unites the algae is their ability to split water, producing molecular oxygen during photosynthesis and concomi tantly assimilating carbon dioxide. This attribute is shared with the terres trial plants, cyanobacteria and chloroxybacteria. Although vascular plants are excluded from this review, we employ a broad definition of algae that includes the photosynthetic, oxygenic procaryotes. Measurements of gas exchange are fundamental to most biochemical, physiological and ecological investigations of the algae.
Download or read book POLAR NIGHT Marine Ecology written by Jørgen Berge and published by Springer Nature. This book was released on 2020-04-08 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: Until recently, the prevailing view of marine life at high latitudes has been that organisms enter a general resting state during the dark Polar Night and that the system only awakens with the return of the sun. Recent research, however, with coordinated, multidisciplinary field campaigns based on the high Arctic Archipelago of Svalbard, have provided a radical new perspective. Instead of a system in dormancy, a new perspective of a system in full operation and with high levels of activity across all major phyla is emerging. Examples of such activities and processes include: Active marine organisms at sea surface, water column and the sea-floor. At surface we find active foraging in seabirds and fish, in the water column we find a high biodiversity and activity of zooplankton and larvae such as active light induced synchronized diurnal vertical migration, and at seafloor there is a high biodiversity in benthic animals and macroalgae. The Polar Night is a period for reproduction in many benthic and pelagic taxa, mass occurrence of ghost shrimps (Caprellides), high abundance of Ctenophores, physiological evidence of micro- and macroalgal cells that are ready to utilize the first rays of light when they appear, deep water fishes found at water surface in the Polar night, and continuous growth of bivalves throughout the winter. These findings not only begin to shape a new paradigm for marine winter ecology in the high Arctic, but also provide conclusive evidence for a top-down controlled system in which primary production levels are close to zero. In an era of environmental change that is accelerated at high latitudes, we believe that this new insight is likely to strongly impact how the scientific community views the high latitude marine ecosystem. Despite the overwhelming darkness, the main environmental variable affecting marine organisms in the Polar Night is in fact light. The light regime during the Polar Night is unique with respect to light intensity, spectral composition of light and photoperiod.

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.
