Download or read book Phenology: An Integrative Environmental Science written by Mark D. Schwartz and published by Springer Science & Business Media. This book was released on 2011-04-28 with total page 567 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phenology is the study of plant and animal life cycle events, which are triggered by environmental changes, especially temperature. Wide ranges of phenomena are included, from first openings of leaf and flower buds, to insect hatchings and return of birds. Each one gives a ready measure of the environment as viewed by the associated organism. Thus, phenological events are ideal indicators of the impact of local and global changes in weather and climate on the earth's biosphere. Assessing our changing world is a complex task that requires close cooperation from experts in biology, climatology, ecology, geography, oceanography, remote sensing and other areas. This book is a synthesis of current phenological knowledge, designed as a primer on the field for global change and general scientists, students and interested members of the public. With contributions from a diverse group of over fifty phenological experts, covering data collection, current research, methods and applications, it demonstrates the accomplishments and potential of phenology as an integrative environmental science.

Download or read book Macroclimate and Plant Forms written by Elgene E. O. Box and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study arose out ofthe old question of what actually determines vegetation structure and distributions. Is climate the overriding control, as one would suppose from reading the more geographically oriented literature? Or is climate only incidental, as suggested by more site and/ or taxon-oriented writers? The question might be phrased more realistically: How much does climate control vegetation processes, structures, and distributions? It seemed to me, as an ambitious doctoral student, that one way to attempt an answer might be to try to predict world vegetation from climate alone and then compare the predicted results with actual vegetation patterns. If climatic data were sufficient to reproduce the world's actual vegetation patterns, then one could conclude that climate is the main control. This book represents an expanded, second-generation version of that original thesis. It presents world-scale vegetation and ecoclimatic models and a methodology for applying such models to predict vegetation and for evaluating model results. This approach also provides a means of geographical simulation of vegetation patterns and changes, which represent necessary data inputs in other fields such as atmospheric chemistry and biogeochemical cycling. It has been fairly well accepted that climatic and other environmental conditions are associated with the evolution of particular aspects of plant form (convergent evolution). The particular configurations of plant size, photosynthetic surface area and structure (e. g. sclerophylly, stomatal 'resistance'), and their seasonal variations represent what one can recognize fairly readily as distinct growth forms.

Download or read book Arctic and Alpine Environments written by Jack D. Ives and published by Routledge. This book was released on 2019-10-08 with total page 1066 pages. Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 1974, Arctic and Alpine Environments examines, the relatively simple ecosystems of arctic and alpine lands that still occupy extensive areas little disturbed by modern technology. The book argues that there is a necessity for carefully controlled development of the resources of these regions and suggests that there is a risk of irreversible disturbance without full understanding of these regions. This book provides a detailed documentation of cold-stressed arctic and alpine terrestrial environments and systematically deals with the present and past physical environment – climate, hydrology and glaciology; biota – treeline, vegetation, vertebrate zoology, and historical biogeography; abiotic processes – geomorphological and pedological and the role of man – bioclimatology, archaeology and technological impact, including radioecology. The book will appeal to academics and students of environmental and biological science, as well as providing a significant source for conservationists’, government agencies and industrial organizations.

Available in PDF, EPUB and Kindle. Book excerpt: Ecologists traditionally regard time as part of the background against which ecological interactions play out. In this book, Eric Post argues that time should be treated as a resource used by organisms for growth, maintenance, and offspring production. Post uses insights from phenology—the study of the timing of life-cycle events—to present a theoretical framework of time in ecology that casts long-standing observations in the field in an entirely new light. Combining conceptual models with field data, he demonstrates how phenological advances, delays, and stasis, documented in an array of taxa, can all be viewed as adaptive components of an organism’s strategic use of time. Post shows how the allocation of time by individual organisms to critical life history stages is not only a response to environmental cues but also an important driver of interactions at the population, species, and community levels. To demonstrate the applications of this exciting new conceptual framework, Time in Ecology uses meta-analyses of previous studies as well as Post’s original data on the phenological dynamics of plants, caribou, and muskoxen in Greenland.

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.

Download or read book Plant Geography written by Rexford Daubenmire and published by Elsevier. This book was released on 2012-12-02 with total page 347 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant Geography: With Special Reference to North America covers main concepts of the two major approaches to plant geography, namely, the floristic plant geography and the ecologic plant geography. Floristic plant geography primarily studies evolutionary divergence, migration, and decline of taxa, as influenced by past events of the earth’s history. Ecologic plant geography is an alternative approach to plant geography, which takes plant communities as units having ranges to be interpreted, dominated by sociologic and physiologic, rather than phylogenetic and historic considerations. Under the floristic plant geography part, topics covered include interrelations among floristic plant geography, taxonomy, and geology; the relation between plant dissemination and migration; evidence of the dynamic character of plant ranges; and migratory route. After a brief introduction to the evolution of North and South America vegetation, the book discusses the ecologic plant geography section that focuses on various vegetation regions in North America, including Tundra, subarctic-subalpine forest, temperate mesophytic, xerophytic forest, and chaparral and steppe regions and temperate affinity forests in Middle America. Other regions examined include the desert and marine regions, as well as the microphyllous woodland, tropical savanna, rain forest, and tropical alpine. With great information on geologic history of each vegetation unit and paleontology, this book will be helpful to paleobotanists, historical geologists, and taxonomists.
