This book was released on 2017 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the greatest unmet challenges in conservation biology is the genetic management of fragmented populations of threatened animal and plant species. More than a million small, isolated, population fragments of threatened species are likely suffering inbreeding depression and loss of evolutionary potential, resulting in elevated extinction risks. Although these effects can often be reversed by re-establishing gene flow between population fragments, managers very rarely do this. On the contrary, genetic methods are used mainly to document genetic differentiation among populations, with most studies concluding that genetically differentiated populations should be managed separately, thereby isolating them yet further and dooming many to eventual extinction Many small population fragments are going extinct principally for genetic reasons. Although the rapidly advancing field of molecular genetics is continually providing new tools to measure the extent of population fragmentation and its genetic consequences, adequate guidance on how to use these data for effective conservation is still lacking. This accessible, authoritative text is aimed at senior undergraduate and graduate students interested in conservation biology, conservation genetics, and wildlife management. It will also be of particular relevance to conservation practitioners and natural resource managers, as well as a broader academic audience of conservation biologists and evolutionary ecologists.

Download or read book Population Dynamics in Variable Environments written by Shripad Tuljapurkar and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: Demography relates observable facts about individuals to the dynamics of populations. If the dynamics are linear and do not change over time, the classical theory of Lotka (1907) and Leslie (1945) is the central tool of demography. This book addresses the situation when the assumption of constancy is dropped. In many practical situations, a population will display unpredictable variation over time in its vital rates, which must then be described in statistical terms. Most of this book is concerned with the theory of populations which are subject to random temporal changes in their vital rates, although other kinds of variation (e. g. , cyclical) are also dealt with. The central questions are: how does temporal variation work its way into a population's future, and how does it affect our interpretation of a population's past. The results here are directed at demographers of humans and at popula tion biologists. The uneven mathematical level is dictated by the material, but the book should be accessible to readers interested in population the ory. (Readers looking for background or prerequisites will find much of it in Hal Caswell's Matrix population models: construction, analysis, and in terpretation (Sinauer 1989) ). This book is in essence a progress report and is deliberately brief; I hope that it is not mystifying. I have not attempted to be complete about either the history or the subject, although most sig nificant results and methods are presented.

Available in PDF, EPUB and Kindle. Book excerpt: How the fur trade changed the North and created the modern Arctic: “The history is fascinating.” —Anchorage Daily News In the early twentieth century, northerners lived and trapped in one of the world’s harshest environments. At a time when government services and social support were minimal or nonexistent, they thrived on the fox fur trade, relying on their energy, training, discipline, and skills. John R. Bockstoce, a leading scholar of the Arctic fur trade who also served as a member of an Eskimo whaling crew, explores the twentieth-century history of the Western Arctic fur trade to the outbreak of World War II, covering an immense region from Chukotka, Russia, to Arctic Alaska and the Western Canadian Arctic. This period brought profound changes to Native peoples of the North. To show its enormous impact, the author draws on interviews with trappers and traders, oral and written archival accounts, research in newspapers and periodicals, and his own field notes from 1969 to the present.

Download or read book Jan Mayen Island in Scientific Focus written by Stig Skreslet and published by Springer Science & Business Media. This book was released on 2013-11-13 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: Jan Mayen is a volcanic island surrounded by the deep Greenland, Iceland and Norwegian Seas. There, atmospheric and oceanic processes unleash potential energy that forces very dynamic interactions between sea and air. This unique geophysical focal point generates climatic variability in northern Europe, and supports marine biological production that sustains the yield of large living resources. The marine populations are clearly fluctuating with variations in climate, and raises questions about effects of man-made climate change. Since the last Ice Age the sinking of Greenland Sea Deep-Water has been a substantial driving force for the Global Thermo-Haline Circulation which feeds warm Atlantic water into the Nordic Seas. Global warming may interact with the deep-water formation and force feedback mechanisms that express themselves beyond imagination. The book addresses such problems to raise an interest for doing research on the island and in its waters. The potentials for doing that increases when the island's Loran-C station closes down in 2005. The book recommends how the international scientific community may gain access to this really challenging arena for local, regional and Global research. It is a blueprint for the logistics required for science to succeed in a very remote and physically demanding place on Earth.

Available in PDF, EPUB and Kindle. Book excerpt: The phenomenon of cyclic population fluctuation in small rodents, and specifically lemmings, has been a major issue in ecology for decades. A number of questions, both truly scientific and also of popular mythology,surround the biology of these animals. Although a tremendous amount of research has been carried out on lemmings, much remains to be resolved. And while the story of the suicidal rodent is now understood as myth, the facts behind the population behavior of lemmings require further study. In this book well-known ecologists Stenseth and Ims have brought together a number of leading experts from both North America and Europe to review our current understanding of the taxonomy, population biology, feeding, and community ecology of lemmings.The authors put this current, but rather fragmentary, understanding of lemming biology into a general population biological context."In many ways we see lemmings as an important model species within population biology,"Stenseth acknowledges in the preface. Starting with the 16th Century, the book's introduction overviews the history of lemming research. The chapters are grouped into theme sections, each prefaced by an introductory review by the editors. The overall result is the most comprehensive and coherent overview of the subject to date.Finally, six appendices give detailed advice on how to study lemmings, which will provide an invaluable reference for research in the future. Contains never-before published material on the Norwegian lemming Lemmus lemmus Includes papers presented at a meeting on lemming biology at the biological station of Konnevesi at the University of Jyvaskyla, Finland Edited and authored by experts in the field

Available in PDF, EPUB and Kindle. Book excerpt: Integrated Population Models: Theory and Ecological Applications with R and JAGS is the first book on integrated population models, which constitute a powerful framework for combining multiple data sets from the population and the individual levels to estimate demographic parameters, and population size and trends. These models identify drivers of population dynamics and forecast the composition and trajectory of a population. Written by two population ecologists with expertise on integrated population modeling, this book provides a comprehensive synthesis of the relevant theory of integrated population models with an extensive overview of practical applications, using Bayesian methods by means of case studies. The book contains fully-documented, complete code for fitting all models in the free software, R and JAGS. It also includes all required code for pre- and post-model-fitting analysis. Integrated Population Models is an invaluable reference for researchers and practitioners involved in population analysis, and for graduate-level students in ecology, conservation biology, wildlife management, and related fields. The text is ideal for self-study and advanced graduate-level courses. - Offers practical and accessible ecological applications of IPMs (integrated population models) - Provides full documentation of analyzed code in the Bayesian framework - Written and structured for an easy approach to the subject, especially for non-statisticians

Download or read book Bird Species written by Dieter Thomas Tietze and published by Springer. This book was released on 2018-11-19 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: The average person can name more bird species than they think, but do we really know what a bird “species” is? This open access book takes up several fascinating aspects of bird life to elucidate this basic concept in biology. From genetic and physiological basics to the phenomena of bird song and bird migration, it analyzes various interactions of birds – with their environment and other birds. Lastly, it shows imminent threats to birds in the Anthropocene, the era of global human impact. Although it seemed to be easy to define bird species, the advent of modern methods has challenged species definition and led to a multidisciplinary approach to classifying birds. One outstanding new toolbox comes with the more and more reasonably priced acquisition of whole-genome sequences that allow causative analyses of how bird species diversify. Speciation has reached a final stage when daughter species are reproductively isolated, but this stage is not easily detectable from the phenotype we observe. Culturally transmitted traits such as bird song seem to speed up speciation processes, while another behavioral trait, migration, helps birds to find food resources, and also coincides with higher chances of reaching new, inhabitable areas. In general, distribution is a major key to understanding speciation in birds. Examples of ecological speciation can be found in birds, and the constant interaction of birds with their biotic environment also contributes to evolutionary changes. In the Anthropocene, birds are confronted with rapid changes that are highly threatening for some species. Climate change forces birds to move their ranges, but may also disrupt well-established interactions between climate, vegetation, and food sources. This book brings together various disciplines involved in observing bird species come into existence, modify, and vanish. It is a rich resource for bird enthusiasts who want to understand various processes at the cutting edge of current research in more detail. At the same time it offers students the opportunity to see primarily unconnected, but booming big-data approaches such as genomics and biogeography meet in a topic of broad interest. Lastly, the book enables conservationists to better understand the uncertainties surrounding “species” as entities of protection.

Available in PDF, EPUB and Kindle. Book excerpt: I guess I always felt even if the world came to an end, McDonald's still would be open. High school sophomore Miranda's disbelief turns to fear in a split second when an asteroid knocks the moon closer to Earth, like "one marble hits another." The result is catastrophic. How can her family prepare for the future when worldwide tsunamis are wiping out the coasts, earthquakes are rocking the continents, and volcanic ash is blocking out the sun? As August turns dark and wintery in northeastern Pennsylvania, Miranda, her two brothers, and their mother retreat to the unexpected safe haven of their sunroom, where they subsist on stockpiled food and limited water in the warmth of a wood-burning stove. Told in a year's worth of journal entries, this heart-pounding story chronicles Miranda's struggle to hold on to the most important resource of all--hope--in an increasingly desperate and unfamiliar world. An extraordinary series debut Susan Beth Pfeffer has written several companion novels to Life As We Knew It, including The Dead and the Gone, This World We Live In, and The Shade of the Moon.
