Download or read book Shrub Steppe written by Alec Rickard and published by Elsevier. This book was released on 2012-12-02 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: Owing to man-made intervention, the shrub-steppe now represents a rapidly disappearing landscape in the arid regions of North America. This book represents a systems-level study of ecological variables affecting water balance, and responses to perturbation. The study focused on a very large, protected, landscape unit, comprising a natural ``watershed'' area located in the semi-arid western United States. Long-term and concurrent data sets were established with a view towards establishing system-level responses to manipulative interventions, and natural perturbations like wildfire. These data sets were established for micrometeorology, climatology, mineral cycling in soils, nutrient and mineral pathways in springs and streams, vegetational dynamics, and population changes on the site. In synthesizing nearly twenty years of data, the more interesting ecosystem level responses concerned vegetational recovery and water balance. For instance, the synthesis uniquely demonstrates the interaction of biotic and non-biotic factors and their integrated effect on regional water balance. However, special attention was also paid to species diversity and the genetic resource pool represented at this site.This book will be of primary interest as a reference resource to land managers and wildlife specialists, and as a research study for scientists interested in systems-level ecology. Conservation-minded citizens who take more than a cursory interest in ecology will also find it interesting.

Book excerpt: The 51 papers in this proceedings include an introductory keynote paper on ecotones and hybrid zones and a final paper describing the mid-symposium field trip as well as collections of papers on ecotones and hybrid zones (15), population biology (6), community ecology (19), and community rehabilitation and restoration (9). All of the papers focus on wildland shrub ecosystems; 14 of the papers deal with one aspect or another of sagebrush (subgenus Tridentatae of Artemisia) ecosystems. The field trip consisted of descriptions of biology, ecology, and geology of a big sagebrush (Artemisia tridentata) hybrid zone between two subspecies (A. tridentata ssp. tridentata and A. t. ssp. vaseyana) in Salt Creek Canyon, Wasatch Mountains, Uinta National Forest, Utah, and the ecotonal or clinal vegetation gradient of the Great Basin Experimental Range, Manti-La Sal National Forest, Utah, together with its historical significance. The papers were presented at the 10th Wildland Shrub Symposium: Shrubland Ecotones, at Snow College, Ephraim, UT, August 12-14, 1998.

Available in PDF, EPUB and Kindle. Book excerpt: The 53 papers in this proceedings include a section celebrating the 25-year anniversary of the Shrub Sciences Laboratory (4 papers), three sections devoted to themes, genetics, and biodiversity (12 papers), disturbance ecology and biodiversity (14 papers), ecophysiology (13 papers), community ecology (9 papers), and field trip section (1 paper). The anniversary session papers emphasized the productivity and history of the Shrub Sciences Laboratory, 100 years of genetics, plant materials development for wildland shrub ecosystems, and current challenges in management and research in wildland shrub ecosystems. The papers in each of the thematic science sessions were centered on wildland shrub ecosystems. The field trip featured the genetics and ecology of chenopod shrublands of east-central Utah. The papers were presented at the 11th Wildland Shrub Symposium: Shrubland Ecosystem Genetics and Biodiversity held at the Brigham Young University Conference Center, Provo, UT, June 13-15, 2000.

Book excerpt: Volume 20 of this series deals with a variety of plant and animal ecology topics.**Despite much recent work on herbivory, little attention has been given to insect herbivores active below ground. Brown and Gange describe the ecological adaptations of insects to this abundant but poor quality food resource, and the responses of plants to this potentially very damaging grazing pressure.**Plants living at high altitude must be able to cope with extreme climatic conditions, low carbon dioxide levels, and high radiation doses. Friend and Woodward describe these adaptations and discuss the degree to which they are genetically determined or merely the product of physiological plasticity.**Thomas presents a modular concept of ecology in which modules contain a resource and its associated consumers, and goes on to examine the general principles which may reflect the various mutualisms between organisms in some example fresh water modular systems.**Finally, West examines the microphytic soil crusts of arid and semi-arid soils. Although information on them is currently limited, they are likely to be important in some ecosystems.
