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.

This book was released on 2013-03-08 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: As human populations expand and have increasing access to technol ogy, two general environmental concerns have arisen. First, human pop ulations are having increasing impact on the earth system, such that we are altering the biospheric carbon pools, basic processes of elemental cycling and the climate system of the earth. Because of time lags and feedbacks, these processes are not easily reversed. These alterations are occurring now more rapidly than at any time in the last several million years. Secondly, human activities are causing changes in the earth's biota that lead to species extinctions at a rate and magnitude rivaling those of past geologic extinction events. Although environmental change is potentially reversible at some time scales, the loss of species is irrevo cable. Changes in diversity at other scales are also cause for concern. Habitat fragmentation and declines in population sizes alter genetic di versity. Loss or introduction of new functional groups, such as nitro gen fixers or rodents onto islands can strongly alter ecosystem processes. Changes in landscape diversity through habitat modification and frag mentation alter the nature of processes within and among vegetation patches. Although both ecological changes altering the earth system and the loss of biotic diversity have been major sources of concern in recent years, these concerns have been largely independent, with little concern for the environmental causes the ecosystem consequences of changes in biodiversity. These two processes are clearly interrelated. Changes in ecological systems cause changes in diversity.

Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on how climate affects or affected the biosphere and vice versa both in the present and in the past. The chapters describe how ecosystems from the Antarctic and Arctic, and from other latitudes, respond to global climate change. The papers highlight plant responses to atmospheric CO2 increase, to global warming and to increased ultraviolet-B radiation as a result of stratospheric ozone depletion.

Download or read book Ecology and Evolution of Flowers written by Lawrence D. Harder and published by OUP Oxford. This book was released on 2006-11-30 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: The reproductive organs and mating biology of angiosperms exhibit greater variety than those of any other group of organisms. Flowers and inflorescences are also the most diverse structures produced by angiosperms, and floral traits provide some of the most compelling examples of evolution by natural selection. Given that flowering plants include roughly 250,000 species, their reproductive diversity will not be explained easily by continued accumulation of case studies of individual species. Instead a more strategic approach is now required, which seeks to identify general principles concerning the role of ecological function in the evolution of reproductive diversity. The Ecology and Evolution of Flowers uses this approach to expose new insights into the functional basis of floral diversity, and presents the very latest theoretical and empirical research on floral evolution. Floral biology is a dynamic and growing area and this book, written by the leading internationally recognized researchers in this field, reviews current progress in understanding the evolution and function of flowers. Chapters contain both new research findings and synthesis. Major sections in turn examine functional aspects of floral traits and sexual systems, the ecological influences on reproductive adaptation, and the role of floral biology in angiosperm diversification. Overall, this integrated treatment illustrates the role of floral function and evolution in the generation of angiosperm biodiversity. This advanced textbook is suitable for graduate level students taking courses in plant ecology, evolution, systematics, biodiversity and conservation. It will also be of interest and use to a broader audience of plant scientists seeking an authoritative overview of recent advances in floral biology.
