Book excerpt: n weathering would result in soils of low or high availability of base cations. The presence or absence of ecological zones (large areas of similar environmental conditions consisting of temperature, moisture, and fertility, which are manifested by characteristic vegetative communities) were modeled as multivariate logistic functions of climatic, topographic, and geologic variables. Accuracy of ecozone models ranged from 69- to 95-percent correct classification of sample plots; accuracy of most models was > 80 percent. The most important model variables were elevation, precipitation amount, and lithologic group. A regional map of ecological zones was developed by using a geographic information system to apply the models to a 30-m digital elevation dataset. Overall map accuracy was refined by adjusting the best probability cut levels of the logistic models based on expert knowledge and familiarity of the authors with known ecological zone boundaries throughout the study area.

Download or read book Ecological Regions of North America written by and published by . This book was released on 1997 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume represents a first attempt at holistically classifying and mapping ecological regions across all three countries of the North American continent. A common analytical methodology is used to examine North American ecology at multiple scales, from large continental ecosystems to subdivisions of these that correlate more detailed physical and biological settings with human activities on two levels of successively smaller units. The volume begins with an overview of North America from an ecological perspective, concepts of ecological regionalization. This is followed by descriptions of the 15 broad ecological regions, including information on physical and biological setting and human activities. The final section presents case studies in applications of the ecological characterization methodology to environmental issues. The appendix includes a list of common and scientific names of selected species characteristic of the ecological regions.

Download or read book Ecoregions written by Robert G. Bailey and published by Springer Science & Business Media. This book was released on 2014-04-03 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global warming and human-driven impacts are changing the World’s ecological zones. This book applies the principles described in Bailey’s Ecosystem Geography: From Ecoregions to Sites, 2nd ed. (Springer 2009, 1st ed. 1996) to describe and characterize the major terrestrial and aquatic ecological zones of the Earth. Bailey’s system for classifying these zones has been adopted by major organizations such as the U.S. Forest Service and The Nature Conservancy and this book is a significant contribution to a long tradition of classifying and studying the world’s ecological regions or ecoregions. It includes two color maps that show the major ecoregions of the continents and oceans. Also included are: - 106 illustrations with 55 in full color - A new chapter on mountains is included. - There are new sections that address concerns about how eco regions are changing under the relentless influence of humans and climate change - Another new feature is the discussion of using eco regional patterns to transfer research results and select sites for detecting climate change effects on ecosystem distribution - Use of ecoregional patterns to design monitoring networks and sustainable landscapes - Fire regimes in different regional ecosystems and their management implications.

Download or read book Agro Ecological Zones in Punjab Pakistan written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2019-12-19 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: A team of scientists and researchers from the University of Agriculture Faisalabad and University of Arid Agriculture Rawalpindi, in collaboration with FAO and Government of Punjab (Agriculture Department) worked together to delineate the Agro-Ecological Zoning (AEZ) in Punjab. AEZ refers to the division of Punjab region into land resource mapping units, having a unique combination of landform, soil and climatic characteristics, and/or land cover. Based on the most up to date collected information on natural resources, climate and agricultural markets, AEZ reveals an enormous potential for crop diversification and productivity. And it is the need of the hour in a country where population is rapidly growing and where climate changes (increases in temperature, changes in rainfall pattern, extreme weather events) evidence the vulnerability of the current agricultural systems. From a side AEZ will help to make smallholder farming a profitable business and overall enhance agriculture efficiency. On the other side, policymakers will be able to use data of AEZ and associated information on land characteristics (soil quality, topography, agricultural land use, yeld etc) to formulate optimal policies for sustainable agricultural production.

Download or read book The Palynology and Micropalaeontology of Boundaries written by Alwynne Bowyer Beaudoin and published by Geological Society of London. This book was released on 2004 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume explores geological boundaries in time and space using palynology and micropalaeontology. Boundaries produce distinct signatures in the micropalaeontological record. They can tell us much about the response of biotic systems to environmental change in both marine and terrestrial realms. Different microfossil groups and geological contexts require their own approaches, definitions and considerations of boundaries. The papers here cover the methodology of boundary identification from biostratigraphical, ecological and palaeoenvironmental perspectives.
