Book Description
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 Description
Contains 31 contributions presenting the results of recent decades' research on the extensive intertidal and inland saline flats of the Arabian Gulf Region, known colloquially as sabkhat. Only relatively recently acknowledged to be valuable ecosystems with research, development, and conservation value, sabkhat are thoroughly explored in this volume by biologists, geologists, archaeologists, ecologists, botanists, zoologists, and other researchers and scientists from many countries. The volume's 31 contributions are organized into three sections: distribution of sabkhat within the Arabian Peninsula and the adjacent countries (13); sabkha ecology (14); and sabkha land use and development (4). The book includes some fairly low-key b & w photographs, charts, and maps. Annotation copyrighted by Book News, Inc., Portland, OR.

Book Description
This book is a part of the Sabkha Ecosystems series which was designed to provide information on sabkha ecosystems of different regions and to add to the collective knowledge available about saline ecosystems. The comprehensive coverage assists the reader gaining a thorough understanding of sabkha geology, hydrology, geomorphology, zoology, botany, ecology and ecosystem functioning, as well as sabkha conservation, utilization and development. Volume I focused on The Arabian Peninsula and Adjacent Countries, volume II was based on describing saline ecosystems of West and Central Asia , volume III referred to Africa and Southern Europe, while volume IV focused on Cash Crop Halophyte and Biodiversity Conservation. The present volume V focuses on Americans.

Book Description
Atriplex canescens (Pursh.) Nutt. is the most widespread species of perennial Atriplex in North America. Throughout its distributional range, A. canescens shows considerable between-population variation. Some of this variation may be due to phenotypic plasticity but most of it appears to be genetic. Mutations, polyploidy, introgressive hybridization, and segregation from interspecific hybrids all appear to have contributed to its extensive heritable variation. Polyploidy is unusually common with numerous chromosome races (2x, 4x, 6x, 8x, 10x, 12x, 14x, 20x). Fourwing saltbush is widely used for reclamation plantings. Proper identification is important to the utilization of fourwing saltbush in such plantings. While many of the races have been formally named as varieties, others have not. Even though differentiated by ploidy, chemical constituents, geographic distribution, and statistical distribution of morphological characters, races may lack sufficient diagnostic characters to allow facile identification, at least in the herbarium. Rather than combining unnamed races under those that do have a taxonomic name, it seems better at present not to use the formal infraspecific categories in treating the fourwing saltbushes, but to consider them all as races. Seed transfer should be within the geographical distribution limits of each race. The most common race, by far, is Occidentalis. We recommend four overlapping seed transfer zones for race Occidentalis in the United States: (1) Northern Intermountain, (2) Western Great Plains, (3) Colorado Plateau/Great Basin/Columbia Basin, and (4) Southwestern. Source seed populations from near the planting sites generally do well; and populations generally perform better when moved south and/or to lower elevations than when moved north and/or up in elevation.
