Book excerpt: Conditions in arctic and alpine ecosystems impose great challenges to the plants and other organisms that live there. Despite this, thousands of plant species worldwide survive or even prosper under the extreme climatic, edaphic, and ecological conditions in the High North (or South) and in the high mountains. Despite the long tradition of alpine and arctic research, there is still much to be discovered. Arctic and alpine plants continue to surprise researchers with their ingenious strategies and adaptations. Today, global warming, the ever-increasing demand for resources, and the development of tourism are growing threats to arctic and alpine plant life, even in the most remote regions of the world. The future of these highly specialized organisms is uncertain. This applies not only to glacial relics and endemics in isolated mountain refugia, but also to tundra areas that were intact until recently and are now under increasing pressure from man-made global changes. This Special Issue presents reviews and research articles that explore historical biogeography, ecology, adaptations, impacts of global change, and conservation issues related to alpine and arctic plants using a variety of ecological, biogeographical, evolutionary, physiological, and genetic approaches.
Download or read book Arctic and Alpine Environments written by Jack D. Ives and published by Routledge. This book was released on 2019-10-08 with total page 1066 pages. Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 1974, Arctic and Alpine Environments examines, the relatively simple ecosystems of arctic and alpine lands that still occupy extensive areas little disturbed by modern technology. The book argues that there is a necessity for carefully controlled development of the resources of these regions and suggests that there is a risk of irreversible disturbance without full understanding of these regions. This book provides a detailed documentation of cold-stressed arctic and alpine terrestrial environments and systematically deals with the present and past physical environment – climate, hydrology and glaciology; biota – treeline, vegetation, vertebrate zoology, and historical biogeography; abiotic processes – geomorphological and pedological and the role of man – bioclimatology, archaeology and technological impact, including radioecology. The book will appeal to academics and students of environmental and biological science, as well as providing a significant source for conservationists’, government agencies and industrial organizations.
Download or read book Physiological Ecology of North American Plant Communities written by Brain F. Chabot and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 704 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although, as W.D. Billings notes in his chapter in this book. the development of physiological ecology can be traced back to the very beginnings of the study of ecology it is clear that the modern development of this field in North America is due in the large part to the efforts of Billings alone. The foundation that Billings laid in the late 1950s came from his own studies on deserts and subsequently arctic and alpine plants, and also from his enormous success in instilling enthusiasm for the field in the numerous students attracted to the plant ecology program at Duke University. Billings' own studies provided the model for subsequent work in this field. Physiological techniques. normally confined to the laboratory. were brought into the field to examine processes under natural environmental conditions. These field studies were accompanied by experiments under controlled conditions where the relative impact of various factors could be assessed and further where genetic as opposed to environmental influences could be separated. This blending of field and laboratory approaches promoted the design of experiments which were of direct relevance to understanding the distribution and abundance of plants in nature. Physiological mechanisms were studied and assessed in the context of the functioning of plants under natural conditions rather than as an end in itself.

Download or read book Plant Adaptation Strategies in Changing Environment written by Vertika Shukla and published by Springer. This book was released on 2017-12-29 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses the crucial aspects of plant adaptation strategies in higher as well as lower plant groups. Stress induced by changing environmental conditions disrupts or alter various physiological and metabolic processes in organisms, however, plants have evolved various defence strategies to cope with external perturbations. The book discusses speciation changes in response to extreme ecological conditions such as cold, heat, aridity, salinity, altitude, incidental UV radiation and high light intensity, which are particularly relevant in the current scenario of global warming. It also explores the effects of human activities and emission of phytotoxic gases. Further, it describes the overall adaptation strategies and the multifaceted mechanisms involved (integrated complex mechanism), ranging from morphological to molecular alterations, focusing on plants’ capabilities to create an inner environment to survive the altered or extreme conditions. This book is a valuable tool for graduate and research students, as well as for anyone working on or interested in adaptation strategies in plants.
Download or read book Ecology and the Environment written by Russell K. Monson and published by Springer. This book was released on 2014-10-02 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, plant biology is considered from the perspective of plants and their surrounding environment, including both biotic and abiotic interactions. The intended audience is undergraduate students in the middle or final phases of their programs of study. Topics are developed to provide a rudimentary understanding of how plant-environment interactions span multiple spatiotemporal scales, and how this rudimentary knowledge can be applied to understand the causes of ecosystem vulnerabilities in the face of global climate change and expansion of natural resource use by human societies. In all chapters connections are made from smaller to larger scales of ecological organization, providing a foundation for understanding plant ecology. Where relevant, environmental threats to ecological systems are identified and future research needs are discussed. As future generations take on the responsibility for managing ecosystem goods and services, one of the most effective resources that can be passed on is accumulated knowledge of how organisms, populations, species, communities and ecosystems function and interact across scales of organization. This book is intended to provide some of that knowledge, and hopefully provide those generations with the ability to avoid some of the catastrophic environmental mistakes that prior generations have made.
Download or read book Vegetation and Production Ecology of an Alaskan Arctic Tundra written by Larry L. Tieszen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 686 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume on botanical research in tundra represents the culmination of four years of intensive and integrated field research centered at Barrow, Alaska. The volume summarizes the most significant results and interpretations of the pri mary producer projects conducted in the U.S. IBP Tundra Biome Program (1970-1974). Original data reports are available from the authors and can serve as detailed references for interested tundra researchers. Also, the results of most projects have been published in numerous papers in various journals. The introduction provides a brief overview of other ecosystem components. The main body presents the results in three general sections. The summary chapter is an attempt to integrate ideas and information from the previous papers as well as extant literature. In addition, this chapter focuses attention on pro cesses of primary production which should receive increased emphasis. Although this book will not answer all immediate questions, it hopefully will enhance future understanding of the tundra, particularly as we have studied it in Northern Alaska.

Download or read book Plants in Alpine Regions written by Cornelius Lütz and published by Springer Science & Business Media. This book was released on 2011-09-29 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book brings together experts from different fields, who used a broad spectrum of methods to investigate the physiological and cellular adaptation of alpine plants from the tree line to the upper limits. Some articles link alpine plant physiology with physiological adaptations observed in polar plants. Tolerance against often high light intensities (including UV), cold or freezing temperatures, in addition to the need for fast tissue development, flowering, and propagation that is managed by alpine plants are to some extent underrepresented in recent research. This volume considers ice formation and winter conditions in alpine plants; the fate of cryophilic algae and microorganisms; cell structural adaptations; sexual reproduction in high altitudes; the physiology of photosynthesis, antioxidants, metabolites, carbon and nitrogen; and the influences of microclimate (temperatures at the plant level, heat tolerance), UV light, weather and ozone. Further information on life processes in alpine extreme environments may additionally yield new insights into the range of adaptation processes in lowland plants.

Download or read book Song of the Alpine written by Joyce Gellhorn and published by Big Earth Publishing. This book was released on 2002 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Celebrating her life-long love for the land above the trees, author Joyce Gellhorn takes readers on a season-by-season tour of the alpine tundra. With clear, readable prose and 140 beautiful color photographs (from her collection that spans some twenty-five years), Gellhorn reveals the subtle wonders of this haunting landscape. The plants and animals that populate this often harsh and unforgiving environment have evolved remarkable strategies for survival in their high mountain home. Faced with bitter cold, scouring winds and fierce storms, they must somehow hold on and still find water and nourishment. Gellhorn tells us how they do it, and the intricacies and precariousness of these strategies are astonishing.The high country of the Colorado Rocky Mountains has been a destination and a home for Joyce Gellhorn for more than fifty years, including some twelve years spent living with her family at the University of Colorado's research station, Science Lodge -- a log cabin at 9,500 feet. Like the snow that would sift through the chinks in the cabin, the alpine, despite its harshness, captured her heart.She writes: The clear mountain air, the scenery, the invigorating feeling of physical activity, and the fascinating plants, animals, and insects captivated me. Through the years, these wind-blown forlorn places continue to excite me. It is their wildness -- untamed and unpredictable. No matter how many times I visit the alpine, even areas I know intimately, it always shows a different face.
