Download or read book Polyextremophiles written by Joseph Seckbach and published by Springer Science & Business Media. This book was released on 2013-05-13 with total page 626 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many Microorganisms and some macro-organisms can live under extreme conditions. For example, high and low temperature, acidic and alkaline conditions, high salt areas, high pressure, toxic compounds, high level of ionizing radiation, anoxia and absence of light, etc. Many organisms inhabit environments characterized by more than one form of stress (Polyextremophiles). Among them are those who live in hypersaline and alkaline, hot and acidic, cold/hot and high hydrostatic pressure, etc. Polyextremophiles found in desert regions have to copy with intense UV irradiation and desiccation, high as well as low temperatures, and low availability of water and nutrients. This book provides novel results of application to polyextremophiles research ranging from nanotechnology to synthetic biology to the origin of life and beyond.

Download or read book Sea Ice written by David N. Thomas and published by John Wiley & Sons. This book was released on 2017-03-06 with total page 666 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past 20 years the study of the frozen Arctic and Southern Oceans and sub-arctic seas has progressed at a remarkable pace. This third edition of Sea Ice gives insight into the very latest understanding of the how sea ice is formed, how we measure (and model) its extent, the biology that lives within and associated with sea ice and the effect of climate change on its distribution. How sea ice influences the oceanography of underlying waters and the influences that sea ice has on humans living in Arctic regions are also discussed. Featuring twelve new chapters, this edition follows two previous editions (2001 and 2010), and the need for this latest update exhibits just how rapidly the science of sea ice is developing. The 27 chapters are written by a team of more than 50 of the worlds’ leading experts in their fields. These combine to make the book the most comprehensive introduction to the physics, chemistry, biology and geology of sea ice that there is. This third edition of Sea Ice will be a key resource for all policy makers, researchers and students who work with the frozen oceans and seas.

Download or read book Snow Algal Communities, Albedo, and Supraglacial Biogeography in Northwestern North America written by Casey B Engstrom and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Snow algae grow on the surface of alpine and polar snowfields in summer, forming blooms known as "red snow" or "watermelon snow". Snow algal blooms reduce albedo, thereby increasing the rate of snowmelt, potentially resulting in earlier loss of snow cover. Snow cover duration impacts summer water supplies for humans and ecosystems, and on glaciers earlier loss of snow results in increased bare ice ablation and loss of glacier mass. A key first step in understanding snow algae albedo, ecology, and biogeography is identifying the species that form snow algal blooms, and mapping the bloom distribution is prerequisite to quantifying their snowmelt impact. The aims of this thesis were twofold: (1) to identify which snow algal species form blooms in southern British Columbia, and (2) to map the spatiotemporal extent of snow algal blooms on glaciers in North America. To address these aims, I analyzed snow algal communities and single cells via amplicon sequencing, and applied machine learning to classify supraglacial blooms in satellite images across 2019-2022. The results of high-throughput sequencing (metabarcoding) showed blooms contained a diverse mixture of Chloromonadinia and Sanguina. Orange and green Chloromonas blooms were most predominant at lower elevations, whereas red Sanguina was most abundant at high alpine sites. Rosette-like cells, widespread in field samples, were long thought to be a life stage of the cosmopolitan and abundant Sanguina nivaloides. By isolating and sequencing individual cells from field samples, we discovered that "rosettes" in fact constitute a novel genus of Chloromonadinia comprising five new species. The results of the remote sensing analysis revealed blooms were perennial and extensive at mid-elevation, low-angle sites on glaciers on the interior side of the Pacific Coast Ranges and throughout the interior mountain ranges. Bloom extent, duration, and intensity was highly variable between years, with the highest algal biomass produced in years and regions with persistent summer snowpack. Across all four summers, blooms affected nearly 5% of the total glaciated area in northwestern North America, but in some regions and years percent cover was as high as 65% per glacier. Altogether, this thesis characterises the algal taxa forming snow blooms in southern British Columbia, and reveals extensive coverage on North American glaciers, suggesting that blooms may play a previously underestimated role in snow and ice loss in this region.

Available in PDF, EPUB and Kindle. Book excerpt: Concern about the climate crisis is widespread as humans struggle to navigate life in uncertain times. From the vantage of a schooner full of artists on an adventure in the high Arctic, biologist Lynne Quarmby explains the science that convinced her of an urgent need to act on climate change and recounts how this knowledge - and the fear and panic it elicited - plunged her into unsustainable action, ending in arrests, lawsuits, and a failed electoral campaign on behalf of the Green Party of Canada. Watermelon Snow weaves memoir, microbiology, and artistic antics together with descriptions of a sublime Arctic landscape. At the top of the warming world, Quarmby struggles with burnout and grief while an aerial artist twirls high in the ship's rigging, bearded seals sing mournfully, polar bears prowl, and glaciers crumble into the sea. In a compelling narrative, sorrow and fear are balanced by beauty and wonder. The author's journey back from a life out of balance includes excursions into evolutionary history where her discoveries reveal the heart of human existence. The climate realities are as dark as the Arctic winter, yet this is a book of lightness and generosity. Quarmby's voice, intimate and original, illuminates the science while offering a reminder that much about the human experience is beyond reason. Inspiring and deeply personal, Watermelon Snow is the story of one scientist's rediscovery of what it means to live a good life at a time of increasing desperation about the future.

Download or read book Arctic Sea Ice Ecology written by Lars Chresten Lund-Hansen and published by Springer Nature. This book was released on 2020-08-07 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book on sea ice ecology is the ecology of sea ice algae and other microorganism as bacteria, meiofauna, and viruses residing inside or at the bottom of the sea ice, called the sympagic biota. Organisms as seals, fish, birds, and Polar bears relies on sea ice but are not part of this biota. A distinct feature of this ecosystem, is the disappearance (melt) every summer and re-establishing in autumn and winter. The book is organized seasonally describing the physical, optical, biological, and geochemical conditions typical of the seasons: autumn, winter, and spring. These are exemplified with case studies based on author’s fieldwork in Greenland, the Arctic Ocean, and Antarctica but focused on Arctic conditions. The sea ice ecosystem is described in the context of climate change, interests, and effects of a decreasing summer ice extent in the Arctic Ocean. The book contains an up to date description of most relevant methods and techniques applied in sea ice ecology research. This book will appeal to university students at Masters or PhD levels reading biology, geosciences, and chemistry.

Download or read book Biology and Ecology of Antarctic Krill written by Volker Siegel and published by Springer. This book was released on 2016-08-03 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book gives a unique insight into the current knowledge of krill population dynamics including distribution, biomass, production, recruitment, growth and mortality rates. Detailed analysis is provided on food and feeding, reproduction and krill behaviour. The volume provides an overview on the aspects of natural challenges to the species, which involve predation, parasites and the commercial exploitation of the resource and its management. A chapter on genetics shows the results of population subdivision and summarizes recent work on sequencing transcriptomes for studying gene function as part of the physiology of live krill. The focus of Chapter 4 is on physiological functions such as biochemical composition, metabolic activity and growth change with ontogeny and season; and will demonstrate which environmental factors are the main drivers for variability. Further discussed in this chapter are the bottle necks which occur in the annual life cycle of krill, and the mechanisms krill have adapted to cope with severe environmental condition.

Available in PDF, EPUB and Kindle. Book excerpt: Chlorophyll a Fluorescence: A Signature of Photosynthesis highlights chlorophyll (Chl) a fluorescence as a convenient, non-invasive, highly sensitive, rapid and quantitative probe of oxygenic photosynthesis. Thirty-one chapters, authored by 58 international experts, provide a solid foundation of the basic theory, as well as of the application of the rich information contained in the Chl a fluorescence signal as it relates to photosynthesis and plant productivity. Although the primary photochemical reactions of photosynthesis are highly efficient, a small fraction of absorbed photons escapes as Chl fluorescence, and this fraction varies with metabolic state, providing a basis for monitoring quantitatively various processes of photosynthesis. The book explains the mechanisms with which plants defend themselves against environmental stresses (excessive light, extreme temperatures, drought, hyper-osmolarity, heavy metals and UV). It also includes discussion on fluorescence imaging of leaves and cells and the remote sensing of Chl fluorescence from terrestrial, airborne, and satellite bases. The book is intended for use by graduate students, beginning researchers and advanced undergraduates in the areas of integrative plant biology, cellular and molecular biology, plant biology, biochemistry, biophysics, plant physiology, global ecology and agriculture.

Download or read book Antarctic Sea Ice Variability in the Southern Ocean-Climate System written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2017-04-24 with total page 83 pages. Available in PDF, EPUB and Kindle. Book excerpt: The sea ice surrounding Antarctica has increased in extent and concentration from the late 1970s, when satellite-based measurements began, until 2015. Although this increasing trend is modest, it is surprising given the overall warming of the global climate and the region. Indeed, climate models, which incorporate our best understanding of the processes affecting the region, generally simulate a decrease in sea ice. Moreover, sea ice in the Arctic has exhibited pronounced declines over the same period, consistent with global climate model simulations. For these reasons, the behavior of Antarctic sea ice has presented a conundrum for global climate change science. The National Academies of Sciences, Engineering, and Medicine held a workshop in January 2016, to bring together scientists with different sets of expertise and perspectives to further explore potential mechanisms driving the evolution of recent Antarctic sea ice variability and to discuss ways to advance understanding of Antarctic sea ice and its relationship to the broader ocean-climate system. This publication summarizes the presentations and discussions from the workshop.

Download or read book Arctic Ecology written by David N. Thomas and published by John Wiley & Sons. This book was released on 2021-01-26 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Arctic is often portrayed as being isolated, but the reality is that the connectivity with the rest of the planet is huge, be it through weather patterns, global ocean circulation, and large-scale migration patterns to name but a few. There is a huge amount of public interest in the ‘changing Arctic’, especially in terms of the rapid changes taking place in ecosystems and exploitation of resources. There can be no doubt that the Arctic is at the forefront of the international environmental science agenda, both from a scientific aspect, and also from a policy/environmental management perspective. This book aims to stimulate a wide audience to think about the Arctic by highlighting the remarkable breadth of what it means to study its ecology. Arctic Ecology seeks to systematically introduce the diverse array of ecologies within the Arctic region. As the Arctic rapidly changes, understanding the fundamental ecology underpinning the Arctic is paramount to understanding the consequences of what such change will inevitably bring about. Arctic Ecology is designed to provide graduate students of environmental science, ecology and climate change with a source where Arctic ecology is addressed specifically, with issues due to climate change clearly discussed. It will also be of use to policy-makers, researchers and international agencies who are focusing on ecological issues and effects of global climate change in the Arctic. About the Editor David N. Thomas is Professor of Arctic Ecosystem Research in the Faculty of Biological and Environmental Sciences, University of Helsinki. Previously he spent 24 years in the School of Ocean Sciences, Bangor University, Wales. He studies marine systems, with a particular emphasis on sea ice and land-coast interactions in the Arctic and Southern Oceans as well as the Baltic Sea. He also edited a related book: Sea Ice, 3rd Edition (2017), which is also published by Wiley-Blackwell.
