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

Download or read book Chaos in Real Data written by J.N. Perry and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chaos in Real Data studies the range of data analytic techniques available to study nonlinear population dynamics for ecological time series. Several case studies are studied using typically short and noisy population data from field and laboratory. A range of modern approaches, such as response surface methodology and mechanistic mathematical modelling, are applied to several case studies. Experts honestly appraise how well these methods have performed on their data. The accessible style of the book ensures its readability for non-quantitative biologists. The data remain available, as benchmarks for future study, on the worldwide web.

Download or read book Arctic Climate Impact Assessment Scientific Report written by Arctic Climate Impact Assessment and published by Cambridge University Press. This book was released on 2005-11-07 with total page 1053 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Arctic is now experiencing some of the most rapid and severe climate change on earth. Over the next 100 years, climate change is expected to accelerate, contributing to major physical, ecological, social, and economic changes, many of which have already begun. Changes in arctic climate will also affect the rest of the world through increased global warming and rising sea levels. Arctic Climate Impact Assessment was prepared by an international team of over 300 scientists, experts, and knowledgeable members of indigenous communities. The report has been thoroughly researched, is fully referenced, and provides the first comprehensive evaluation of arctic climate change, changes in ultraviolet radiation and their impacts for the region and for the world. It is illustrated in full color throughout. The results provided the scientific foundations for the ACIA synthesis report - Impacts of a Warming Arctic - published by Cambridge University Press in 2004.

This book was released on 2020-10-07 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Available online: http://urn.kb.se/resolve?urn=urn:nbn:se:norden:org:diva-6156 Aim: To explore possible adverse health effects of high soy intake among children and pregnant women (unborn children) in the Nordic countries. Methods: A dietary exposure scenario with a high soy content was created based on Danish data on the diet of women (18-45 yrs) and children (4-10 yrs). The literature was searched for relevant studies for a risk assessment of isoflavones. Results: Minor changes in the intake of energy and macronutrients, and no changes to the degree of fulfilling recommended intake levels for most micronutrients were found. Health-based guidance values for genistein intake by pregnant women (unborn children) of 0.09 mg/kg bw/day and for children of 0.07 mg/kg bw/day were established. Conclusion: Estimated exposure to the isoflavone genistein from a diet with high soy content indicated a potential health concern for children and no concern for the unborn child.

Book excerpt: A comprehensive monograph of the beautiful Snowy Owl, famed for its elegant, all-white plumage. The Snowy Owl needs little introduction. This massive white owl breeds throughout the Arctic, wherever there are voles or lemmings to hunt, from Scandinavia through northern Russia to Canada and Greenland. Southerly movements in winter see North American birds travel as far south as the northern United States, while infrequent vagrants on the Shetlands and other northern isles are a magnet for birders. The Snowy Owl gives this popular bird the full Poyser treatment, with sections on morphology, distribution, palaeontology and evolution, habitat, breeding, diet, population dynamics, movements, interspecific relationships and conservation, supported by some fabulous photography. The award-winning author team also had access to Russian research literature, which is generally out of reach for Western scientists.
