This book provides case studies and general views of the main processes involved in the ecosystem shifts occurring in the high mountains and analyses the implications for nature conservation. Case studies from the Pyrenees are preponderant, with a comprehensive set of mountain ranges surrounded by highly populated lowland areas also being considered. The introductory and closing chapters will summarise the main challenges that nature conservation may face in mountain areas under the environmental shifting conditions. Further chapters put forward approaches from environmental geography, functional ecology, biogeography, and paleoenvironmental reconstructions. Organisms from microbes to large carnivores, and ecosystems from lakes to forest will be considered. This interdisciplinary book will appeal to researchers in mountain ecosystems, students and nature professionals. This book is open access under a CC BY license.
Gabriel Marcel (1889-1973) stands outside the traditional canon of twentieth-century French philosophers. Where he is not simply forgotten or overlooked, he is dismissed as a 'relentlessly unsystematic' thinker, or, following Jean-Paul Sartre's lead, labelled a 'Christian existentialist' - a label that avoids consideration of Marcel's work on its own terms. How is one to appreciate Marcel's contribution, especially when his oeuvre appears to be at odds with philosophical convention? Helen Tattam proposes a range of readings as opposed to one single interpretation, a series of departures or explorations that bring his work into contact with critical partners such as Henri Bergson, Paul Ricoeur and Emmanuel Lévinas, and offer insights into a host of twentieth-century philosophical shifts concerning time, the subject, the other, ethics, and religion. Helen Tattam's ambitious study is an impressively lucid account of Marcel's engagement with the problem of time and lived experience, and is her first monograph since the award of her doctorate from the University of Nottingham.
Plants make up 99.9 percent of the world's living matter, provide food and shelter, and control the Earth's climate. The study of plant ecology is therefore essential to understanding the biological functions and processes of the biosphere. This vibrant introductory textbook integrates important classical themes with recent ideas, models and data. The book begins with the origin of plants and their role in creating the biosphere as the context for discussing plant functional types and evolutionary patterns. The coverage continues logically through the exploration of causation with chapters, amongst others, on resources, stress, competition, predation, and mutualism. The book concludes with a chapter on conservation, addressing the concern that as many as one-third of all plant species are at risk of extinction. Each chapter is enriched with striking and unusual examples of plants (e.g., stone plants, carnivorous plants) and plant habitats (e.g., isolated tropical tepui, arctic cliffs). Paul Keddy writes in a lively and thought-provoking style which will appeal to students at all levels.
