Book Synopsis Experimental Ecology by : William J. Resetarits
Download or read book Experimental Ecology written by William J. Resetarits and published by . This book was released on 2001 with total page 492 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experimentation is a dominant approach in contemporary ecological research, pervading studies at all levels of biological organization and across diverse taxa and habitats. Experimental Ecology assembles an eminent group of ecologists who synthesize insights from these varied sources into a cogent statement about experimentalism as an analytical paradigm, placing experimentation within the larger framework of ecological investigation. The book discusses diverse experimental approaches ranging from laboratory microcosms to manipulation of entire ecosystem, illustrating the myriad ways experiments strengthen ecological inference. Experimental ecologists critique their science to move the field forward on all fronts: from better designs, to better links between experiments and theory, to more realism in experiments targeted at specific systems and questions.

Book Synopsis Responses to Climate Change in the Cold Biomes by : Hans J. De Boeck
Download or read book Responses to Climate Change in the Cold Biomes written by Hans J. De Boeck and published by Frontiers Media SA. This book was released on 2019-06-05 with total page 165 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change is thought to be especially relevant to ecosystems in the cold biomes. Observed warming has been higher in cold climates through various positive feedbacks, especially declining snow and ice cover, and climate projections indicate further rapid warming in the decades to come. Temperature change can have profound impacts in cold biome ecosystems, either directly in terms of impacts on physiology or growing season length, or indirectly via changes in nutrient cycling. The regions focused on here are the (sub)arctic and the (sub)alpine areas, both characterized by short growing seasons and low annual temperatures, but with different radiation environments depending on latitude. Climate change can have impacts in all seasons. Increased spring temperatures can accelerate snowmelt, leading to an earlier onset of the growing season, while warmer summers may stimulate primary productivity through temperatures closer to metabolic optima and/or increased mineralization rates. Winter warming can lead to the vegetation being damaged because of exposure to harsh frost without insulating snow cover. In all of this, concurrent changes in precipitation also play an important role: increased snowfall can buffer warming-induced advances in snowmelt, a higher ratio of rain to snow can greatly accelerate snowmelt in winter and spring, and summer drought may reverse growth-stimulation by warming directly (drought stress) or indirectly (e.g. impaired nutrient uptake). Micro-climate is crucial in these systems and requires particular attention as it can vary widely across the landscape, creating different growing environments in the space of a few meters or even less. Interest in cold region responses to climate change does not only arise from the fact that they harbor unique ecosystems that may be endangered, but also because they store large amounts of carbon that may be released under climate change. However, research is challenging because of the remoteness of many of these areas and the harsh conditions during much of the year. In spite of this, some studies have been carried out over an extensive period, spanning decades and yielding information on for example plant community reorganization (including invasions), and changes in phenology above- and/or belowground. Other studies focus on shorter term effects, such as impacts of heat waves, late frosts or other anomalous weather, including longer term (after-) effects that may differ drastically from other regions because of the short growing season in cold climates. Ultimately, models are used to predict future changes in vegetation along latitudinal or elevational gradients, although phenology and microclimatic variation may pose particular challenges. Contributions to this Research Topic focus on climate change, encompassing both changes in the mean (gradual warming) and variability (heat waves, altered precipitation distribution) in cold biomes. The Topic contains reports on observed changes or events, but also research making use of experimentally imposed environmental changes. The focus is varied, including phenology, physiology, soil and vegetation science and biogeochemistry, with the aim of providing a comprehensive overview of observed and expected responses to climate change in cold biome ecosystems.

This book was released on 2001-11-30 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The lack of discussion of the life histories of modular organisms is the weakness of this book that I most regret. . . . Modular organisms are different. " S. C. Steams: The Evolution of Life Histories (1992) Life-history theory endeavours to increase our understanding of the processe,s whereby the broad features of the life cycles of organisms, such as the timing and magnitude of reproduction, have evolved. Although reproductive traits have dominated as study objects due to their immediate importance for evolutionary success, much work has also been conducted on patterns of development, growth and senescence, as well as on the shifts in resource allocation related to these processes. The basic axiom of life-history theory is that patterns of life histories, such as reproductive traits, are subject to evolutionary explanation. This idea can be traced back at least as far as Darwin's Origin of Species (1859). In his discussion of plant domestication, Darwin wrote: "I cannot doubt that the continued selection of slight variations, either in the leaves, the flowers, or the fruit, will produce races differing from each other chiefly in these characters". Darwin was impressed by the success of plant breeders in moulding the growth and reproductive parameters of cultivated plants, and believed that natural selection could have a similar impact in natural populations.

Book Synopsis Plant Biosystematics by : William F. Grant
Download or read book Plant Biosystematics written by William F. Grant and published by Elsevier. This book was released on 2013-09-25 with total page 691 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant Biosystematics is a compendium of papers from a symposium titled "Plant Biosystematics: Forty Years Later" held in Montreal in July 1983. This collection reviews the current field of biosystematics, particularly the evolution of natural biota, and how plant biosystematics can contribute to the welfare of humans. One paper reviews biosystematics, compares new approaches, and discusses the latest trend in comparative, molecular evolution of genes. One author discusses the cytology and biosystematics concerning the discontinuities and genetic independence occurring in the evolutionary process. Another author discusses chromosome pairing in species and hybrids that includes models of chromosome pairing in diploids. The text also describes chromosome banding and biosystematics, as well as the problems of chromosome banding that should be addressed to in future research. With estimates of the number of species being threatened with extinction numbering around 20,000 one paper address the issue of conservation and biosystematics. The author suggests that more biological information should be published to avoid duplication of effort, and possibly drive scientists to have their views more widely felt. Agriculturists, botanists, conservationists, environmentalists, and researchers in the field of botany, conservation, and plant genealogy will find this book valuable.
Book Synopsis Climate Change, Ecology and Systematics by : Trevor R. Hodkinson
Download or read book Climate Change, Ecology and Systematics written by Trevor R. Hodkinson and published by Cambridge University Press. This book was released on 2011-04-28 with total page 543 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change has shaped life in the past and will continue to do so in the future. Understanding the interactions between climate and biodiversity is a complex challenge to science. With contributions from 60 key researchers, this book examines the ongoing impact of climate change on the ecology and diversity of life on earth. It discusses the latest research within the fields of ecology and systematics, highlighting the increasing integration of their approaches and methods. Topics covered include the influence of climate change on evolutionary and ecological processes such as adaptation, migration, speciation and extinction, and the role of these processes in determining the diversity and biogeographic distribution of species and their populations. This book ultimately illustrates the necessity for global conservation actions to mitigate the effects of climate change in a world that is already undergoing a biodiversity crisis of unprecedented scale.

Book Synopsis The Theory of Evolution by : Samuel M. Scheiner
Download or read book The Theory of Evolution written by Samuel M. Scheiner and published by University of Chicago Press. This book was released on 2020-01-07 with total page 455 pages. Available in PDF, EPUB and Kindle. Book excerpt: Darwin’s nineteenth-century writings laid the foundations for modern studies of evolution, and theoretical developments in the mid-twentieth century fostered the Modern Synthesis. Since that time, a great deal of new biological knowledge has been generated, including details of the genetic code, lateral gene transfer, and developmental constraints. Our improved understanding of these and many other phenomena have been working their way into evolutionary theory, changing it and improving its correspondence with evolution in nature. And while the study of evolution is thriving both as a basic science to understand the world and in its applications in agriculture, medicine, and public health, the broad scope of evolution—operating across genes, whole organisms, clades, and ecosystems—presents a significant challenge for researchers seeking to integrate abundant new data and content into a general theory of evolution. This book gives us that framework and synthesis for the twenty-first century. The Theory of Evolution presents a series of chapters by experts seeking this integration by addressing the current state of affairs across numerous fields within evolutionary biology, ranging from biogeography to multilevel selection, speciation, and macroevolutionary theory. By presenting current syntheses of evolution’s theoretical foundations and their growth in light of new datasets and analyses, this collection will enhance future research and understanding.

Book Synopsis Approaches to Plant Evolutionary Ecology by : Gregory Paul Cheplick
Download or read book Approaches to Plant Evolutionary Ecology written by Gregory Paul Cheplick and published by Oxford University Press, USA. This book was released on 2015 with total page 307 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant evolutionary ecology is a rapidly growing discipline which emphasizes that populations evolve and adapt not in isolation, but in relation to other species and abiotic environmental features such as climate. By combining approaches from the traditional evolutionary and ecological fields of study, evolutionary ecology is connected to branches of population biology, genetics, botany, conservation, and to other fields of applied science, primarily through shared concepts and techniques. However, other books regarding evolutionary ecology typically focus on animals, creating a substantial need for a synthesis of the scholarly literature with an emphasis on plants. Approaches to Plant Evolutionary Ecology is the first book to specifically explore the evolutionary biology of plant populations. Renowned plant ecologist G. P. Cheplick summarizes and synthesizes much of the primary literature regarding evolutionary perspective. The book also provides summaries of both traditional (common gardens, reciprocal transplants) and modern (molecular genetic) approaches used to address questions about plant adaptation to a diverse group of abiotic and biotic factors. Cheplick provides a rigorously written introduction to the rapidly growing field of plant evolutionary ecology that will appeal to undergraduate and graduate students with an interest in ecology and evolution, as well as educators who are teaching courses on related topics. -- from back cover.
