Book Synopsis Conservation of Plant and Abiotic Diversity in Grazed and Ungrazed Meadows of the Sierra Nevada by : Kathren Murrell Stevenson
Download or read book Conservation of Plant and Abiotic Diversity in Grazed and Ungrazed Meadows of the Sierra Nevada written by Kathren Murrell Stevenson and published by . This book was released on 2004 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Chapter one evaluated our field method using surface moisture classes at the end of August to track species change across the gradient in Kern Plateau meadows, California. As individual species distributions and composition as a whole changed across our a priori moisture classes, and as ordination results showed that moisture class described the majority of variation in species composition, we determined that this method was a good surrogate for the complex hydrologic gradient. Chapter two examined how impacts on physical characteristics in meadows affect biodiversity. Habitats were characterized by hydrology (moisture class), topography, and gross vegetation physiognomy. Species richness was significantly correlated with habitat richness but not species pool. Diversity on non-channel habitats significantly exceeded that of channel habitats when overhanging banks were removed from the analysis, highlighting the importance of overhanging banks on incised channels. Species richness was higher in dry habitats, but wet habitats had a higher proportion of meadow-dependent species. Stringers were significantly higher in species richness than main meadows. We concluded that habitat richness was more important than species pool in determining species richness, that non-channelized habitats and stringers contributed most to plant diversity, and that grazing intensity should be controlled in important habitat types: stringers, overhanging banks and willow. Chapter 3 addressed grazing impacts on channel morphology and incision, moisture class, and species composition by sampling southern Sierra Nevada grazed and ungrazed meadows. Grazed meadows had a significantly higher channel width-to-depth ratio than ungrazed meadows. Channel depth, channel width-to-depth ratio, grazing, and year all significantly affected moisture class distribution. Both greater width-to-depth ratios and grazing were associated with drier moisture classes. Ordination results indicated that grazing, year, and position in basin correlated with the first three axes, explaining 23% of the species data variation. Six ungrazed meadow indicator species, or 43%, were megaforbs, even though megaforbs constitute only 4% of the total flora. We concluded that cow/calf seasonal grazing is correlated with physical changes in meadow physiography, and that these changes affect moisture class availability and therefore habitat availability. Megaforbs are especially susceptible to impacts of grazing in montane and sub-alpine meadows."--Abstract

Book Synopsis Ecological Regions of North America by :
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.

Book Synopsis Missouri Landscapes by : Jon L. Hawker
Download or read book Missouri Landscapes written by Jon L. Hawker and published by . This book was released on 1992 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: "In this magnificent book, Oliver Schuchard provides more than sixty-five exquisite black-and-white photographs spanning his thirty-eight years of photography. In addition, he explains the aesthetic rationale and techniques he used in order to produce these photographs, emphasizing the profound differences between, yet necessary interdependence of, craft and content. Although Schuchard believes that craft is important, he maintains that the idea behind the photograph and the emotional content of the image are equally vital and are, in fact, functions of one another. The author also shares components of his life experience that he believes helped shape his development as an artist and a teacher. He chose the splendid photographs included in this book from among nearly 5,000 negatives that had been exposed all over the world, from Missouri to Maine, California, Alaska, Colorado, France, Newfoundland, and Hawaii, among many other locations. Approximately 250 negatives survived the initial review, and each of those was printed before a final decision was made on which photographs were to be featured in the book. The final choices are representative of Schuchard's work and serve to substantiate his belief that craft, concept, and self must be fully understood and carefully melded for a good photograph to occur. This amazing work by award-winning photographer Oliver Schuchard will be treasured by professional and amateur photographers alike, as well as by anyone who simply enjoys superb photography."--Publishers website.
Book Synopsis Ecophysiology of High Salinity Tolerant Plants by : M. Ajmal Khan
Download or read book Ecophysiology of High Salinity Tolerant Plants written by M. Ajmal Khan and published by Springer Science & Business Media. This book was released on 2006-05-16 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: The halophytes are highly specialized plants, which have greater tolerance to salt. They can germinate, grow and reproduce successfully in saline areas which would cause the death of regular plants. Most halophytic species are found in salt marsh systems along seashores or around landlocked inland lakes and flat plains with high evaporation. The halophytes play very significant role in the saline areas specially in the coast by overcoming the salinity in different ways, viz. with regulating mechanisms in which excess salts are excreted and with out regulating mechanism, which may include succulents or cumulative types. Besides that they protect coast from erosion and cyclones, provide feeding ground and nursery for fish, shrimps and birds. Halophytes get increasing attention today because of the steady increase of the salinity in irrigation systems in the arid and semi-arid regions where the increasing population reaches the limits of freshwater availability. In many countries, halophytes have been successfully grown on saline wasteland to provide animal fodder and have the potential for rehabilitation and even reclamation of these sites. The value of certain salt-tolerant grass species has been recognized by their incorporation in pasture improvement programs in many salt affected regions throughout the world. There have been recent advances in selecting species with high biomass and protein levels in combination with their ability to survive a wide range of environmental conditions, including salinity.
