Download or read book Temporal Dynamics and Ecological Process written by Colleen K. Kelly and published by Cambridge University Press. This book was released on 2014-01-16 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: In contrast with the fundamental ecological expectation that similarity induces competition and loss of species, temporal dynamics allows similar species to co-occur. In fact, the coexistence of similar species contributes significantly to species diversity and could affect ecosystem response to climate change. However, because temporal processes take place over time, they have often been a challenge to document or even to identify. Temporal Dynamics and Ecological Process brings together studies that have met this challenge and present two specific aspects of temporal processes: reproductive scheduling and the stable coexistence of similar species. By using plants to extract general principles, these studies uncover deep ties between temporal niche dynamics and the above central ecological issues, thereby providing a better understanding of what drives temporal processes in nature. Written by leading scientists in the field, this title will be a valuable source of reference to research ecologists and those interested in temporal ecology.

Download or read book Grasses of the Great Plains written by James Stubbendieck and published by Texas A&M University Press. This book was released on 2017-02-17 with total page 736 pages. Available in PDF, EPUB and Kindle. Book excerpt: A vast swath of prairie situated between the Missouri River and the Rocky Mountains, the North American Great Plains extend across ten states in the United States and three provinces in Canada. The dominant vegetation is grass—both the native species that have long thrived here and the cultivated crops such as corn, wheat, and sorghum that are the result of human agricultural activity. This comprehensive guide, written by three grass specialists, is an invaluable tool for identification of the approximately 450 species of grasses that occur on the Great Plains. In each description, the authors cover distribution, habitat, forage value, and toxicity and include a detailed black-and-white illustration of the grass as well as a range map. Intended as a reference for landowners, rangeland specialists, students, state and federal agency professionals, and nongovernment conservation organizations, Grasses of the Great Plains will serve a wide audience of users involved in and dedicated to grassland management.

Download or read book Manual of Grasses for North America written by Mary E. Barkworth and published by University Press of Colorado. This book was released on 2007-09-30 with total page 1552 pages. Available in PDF, EPUB and Kindle. Book excerpt: Grasses are the world’s most important plants. They are the dominant species over large parts of the earth’s land surface, a fact that is reflected in the many different words that exist for grasslands, words such as prairie, veldt, palouse, and pampas to mention just a few. As a group, grasses are of major ecological importance, as soil binders and providers of shelter and food for wild animals, both large and small. Some grasses, such as wheat, rice, corn, barley, rye, tef, and sugar cane are major sources of calories for humans and their livestock; others, primarily bamboos, are used for construction, tools, paper, and fabric. More recently, the seed catalogs that tantalize gardeners each winter have borne witness to an increasing appreciation of the aesthetic value of grasses. The Manual of Grasses for North America is designed as a successor to the classic volume by Hitchcock and Chase. It reflects current taxonomic thought and includes keys, illustrations, and distribution maps for the nearly 900 native and 400 introduced species that have been found in North America north of Mexico. In addition, it presents keys and illustrations for several species that are known only in cultivation or are of major agricultural significance, either as progenitors of bread wheat and corn or as a major threat to North American agriculture because of their ability to hybridize with crop species. The Manual is a major reference work for grasses that will retain its value for many years.

Download or read book Plants of China written by De-Yuan Hong and published by Cambridge University Press. This book was released on 2015-04-23 with total page 490 pages. Available in PDF, EPUB and Kindle. Book excerpt: The flora of China is astonishing in its diversity. With 32,500 species of vascular plants, over fifty per cent of which are endemic, it has more botanical variety than anywhere else in the world and provides unbroken connections to all its landscapes - from tropical to subtropical, temperate and boreal forests. This book tells the story of the plants of China: from the evolution of the flora through time to the survey of the bioclimatic zones, soundly based on chapters with information on climate, physical geography and soils. The history of botany and its study are also examined, with chapters dedicated to forestry, medicinal plants and ornamentals, with the changing flora, aliens, extinction and conservation also discussed. An essential read for years to come, The Plants of China shows that an understanding of the flora of China is crucial to interpreting plant evolution and fossil history elsewhere in the world.

Download or read book Soils Plant Growth and Crop Production Volume III written by Willy H. Verheye and published by EOLSS Publications. This book was released on 2010-11-30 with total page 492 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soils, Plant Growth and Crop Production is a component of Encyclopedia of Food and Agricultural Sciences, Engineering and Technology Resources in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty Encyclopedias. Plants, and crops in particular, grow and develop through the uptake of water and nutrients by the root system in soils and their transformation into biomass through processes governed by photosynthesis. The quality and amount of products harvested from this biomass depend largely on the intrinsic properties of the soil, i.e. the moisture and nutrients made available for uptake by the roots. These volumes describe in a synthetic form the impact of the most important soil properties on general agronomy, crop production, cultivation methods, and yields, including the specific management aspects which take away some production constraints. Changes in general agronomy as a result of plant breeding, climatic change and competition between newly introduced crops are discussed. The three volumes with contributions from distinguished experts in the field discusses about soils, plant growth and crop production in several related topics. These volumes are aimed at the following five major target audiences: University and College students Educators, Professional practitioners, Research personnel and Policy analysts, managers, and decision makers and NGOs.

Download or read book The Vegetation of Georgia South Caucasus written by George Nakhutsrishvili and published by Springer Science & Business Media. This book was released on 2012-08-23 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book describes richness and diversity of Georgia’s vegetation. Contrasting ecosystems coexist on the relatively small territory of the country and include semi-deserts in East Georgia, Colchic forests with almost sub-tropical climate in West Georgia and subnival plant communities in high mountains. West Georgia lacks xerophilous vegetation zone and mesophilous forest vegetation spreads from the sea level to subalpine zone. The Colchic refugium (West Georgia) ensured survival of the Tertiary’s mesophilous forest flora. Vertical profile of the vegetation is more complex in East Georgia with semi-desert, steppe and arid open forest zone. In South Georgia the montane zone represented by montane steppe is devoid of forests
