Available in PDF, EPUB and Kindle. Book excerpt: The movement of tree species in either latitude or elevation has attracted increased recent attention due to growing national / international concerns over climate change. However, studies on tree species movements began in the early 1970s in the White Mountains of New Hampshire, mostly due to ecological interests in episodic behavior of upper-elevation tree species on some of the most scenic mountains. Observations taken while making elevation transects appeared to indicate that regeneration of some species was advancing or retreating in relation to the main stand of mature trees. The process was formalized into a graphical model that would predict rates of movement which was then tested on the Bartlett Experimental Forest located in the White Mountains National Forest. This paper describes several types of migrational models that were developed as well as long-term remeasured plot evidence against significant recent changes in the species distributions.
Book Synopsis Migration of Tree Species in New England Based on Elevational and Regional Analyses by : Dale S. Solomon

This book was released on 1994 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concerns over possible increases in global temperature have renewed interest in the detection, measurement, and analysis of tree-species migration. Previous work has consisted mostly of computer simulations of changes in species ranges. In this study, two complementary approaches were used to examine movements of tree species in New England, where there is a documented increase (at Hanover, New Hampshire) in mean annual and summer temperatures of about 2OC since 1835. We used advancing-front theory to examine age trends over distance and elevation in undisturbed stands on Haystack Mountain in New Hampshire. Then we examined changes in species occurrence over a 24-year period on USDA Forest Service survey plots throughout Maine. On Haystack Mountain, well-defined stationary fronts (no movement) were identified for red spruce (Picea rubens Sarg.) and beech (Fagus grandifolia Ehrh.); these occurred at the borders of distinct changes in site conditions, which serve as temporary obstacles to species' movements. A catastrophic front was depicted for sugar maple (Acer saccharum Marsh.): no established understory stems less than about 100 years old were evident at elevations above 720 m on a site complex composed of shallow bedrock interspersed with deeper till. A constant, very slowly moving advancing front was exhibited by hemlock (Tsuga canadensis (L.) Carr.). In Maine, white pine (Pinus strobus L.), and balsam fir (Abies balsamea (L.) (Mill.) decreased significantly in average latitude and elevation over the 24-year period; average species' elevations decreased by only 16 and 7 m, respectively, while latitudes decreased (southerly) by about 0.1 and 0.04 degrees (1 1.3 to 4.5 km). The other significant change was an increase (westerly) in longitude of sugar maple by about 0.1 degree (6.9 km). Succession--not climatic shifts-- following land use changes or cutting probably was responsible for these trends for sugar maple. Forest managers should be aware that natural succession as influenced by disturbance, land use, and site currently is the dominant influence affecting species changes in New England forests. At present, potential ranges of the major species in terms of elevation and regional position appear stable and in alignment with known site requirements.

Available in PDF, EPUB and Kindle. Book excerpt: Essentials of Ecology, 4th Edition presents introductory ecology in an accessible, state-of-the-art format designed to cultivate the novice student's understanding of, and fascination with, the natural world. This new edition has been updated throughout, with new, full-color illustrations, and comes with an accompanying website with downloadable illustrations, multiple-choice questions, and interactive models.
Book Synopsis Paleopalynology by : Alfred Traverse
Download or read book Paleopalynology written by Alfred Traverse and published by Springer Science & Business Media. This book was released on 2007-05-21 with total page 816 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides complete coverage of all aspects of the study of all fossil palynomorphs yet studied. It is a profusely illustrated treatment. The book serves both as a student text and general reference work. Palynomorphs yield information about age, geological and biological environment, climate during deposition, and other significant factors about the enclosing rocks. Extant spores and pollen are treated first, preparing the student for more difficult work with fossil sporomorphs and other kinds of palynomorphs. An appendix describes laboratory methods. The glossary, bibliographies and index are useful tools for study of the literature.

Book Synopsis Past and Future Rapid Environmental Changes by : Brian Huntley
Download or read book Past and Future Rapid Environmental Changes written by Brian Huntley and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: Numerous experts including ecologists, geneticists, paleontologists and climatologists, investigate the response of terrestrial organisms to changes in their environment. The volume comprises an introductory and a final chapter by the editors as well as another 35 contributions. These are divided into six sections: 1. past environmental changes - the late-Quaternary; 2. spatial responses to past changes; 3. mechanisms enabling spatial responses; 4. evolutionary responses to past changes; 5. mechanisms enabling evolutionary responses; 6. predicted future environmental changes and simulated responses. The overwhelming and unanimous conclusion of all contributors is that forecasted global environmental changes pose a severe threat to the integrity of ecosystems worldwide and to the survival of at least some species.
Book Synopsis Modern Biogeochemistry by : V.N. Bashkin
Download or read book Modern Biogeochemistry written by V.N. Bashkin and published by Springer Science & Business Media. This book was released on 2007-05-08 with total page 493 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern Biogeochemistry is aimed to generalize modern ideas of biogeochemical developments during the last decades. It is designed to support a general course in biogeochemistry, and as such, is likely to have a broad market among the many universities and colleges that are adding such courses to their curricula. This book aims to supplement the existing textbooks by providing modern understanding of biogeochemistry, from evolutionary biogeochemistry to practical applications of biogeochemical ideas such as human biogeochemistry, biogeochemical standards and biogeochemical technologies. To a certain extent this textbook is a summary of both scientific results of various authors and classes in biogeochemistry, that have been given to students by authors during the last 5 to 10 years at different universities throughout the world such as Cornell, Moscow, Seoul and Bangkok. Biogeochemistry is becoming an increasingly popular subject for graduate and postgraduate education. Courses in ecology, geography, biology, chemistry, environmental science, public health and environmental engineering all tend to have a biogeochemical component in their syllabuses to a greater or lesser extent.
