Download or read book Status of Pollinators in North America written by National Research Council and published by National Academies Press. This book was released on 2007-05-13 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pollinators-insects, birds, bats, and other animals that carry pollen from the male to the female parts of flowers for plant reproduction-are an essential part of natural and agricultural ecosystems throughout North America. For example, most fruit, vegetable, and seed crops and some crops that provide fiber, drugs, and fuel depend on animals for pollination. This report provides evidence for the decline of some pollinator species in North America, including America's most important managed pollinator, the honey bee, as well as some butterflies, bats, and hummingbirds. For most managed and wild pollinator species, however, population trends have not been assessed because populations have not been monitored over time. In addition, for wild species with demonstrated declines, it is often difficult to determine the causes or consequences of their decline. This report outlines priorities for research and monitoring that are needed to improve information on the status of pollinators and establishes a framework for conservation and restoration of pollinator species and communities.

Download or read book The Ecoregions of Saskatchewan written by G. A. Padbury and published by University of Regina Press. This book was released on 1998 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the ecoregions of Saskatchewan, following a hierarchical framework for terrestrial ecosystems in Canada. The introduction reviews ecological land classification and the various interrelated factors that are involved in the development of ecosystems: geology, water, climate, vegetation, soils, wildlife, and human impacts. The main section describes the province within the context of the four ecozones and 11 ecoregions that were identified in the framework. For each ecoregion, the book provides a description of the physical setting, such as geology & climate, as well as the biological features that have developed in response to this physical environment. The impact of human activities on the ecology of the area concludes each of these descriptions. Appendices include lists of animal & plant species found in Saskatchewan and a glossary.
Download or read book Forage Crops in the Aspen Parklands of Western Canada written by S. E. Beacom and published by . This book was released on 1991 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: The production of perennial forage crops has a vital role to play in diversifying the agricultural economy of the prairies and maintaining the productivity of the soil. This bulletin provides data obtained from grazing trials conducted at the Melfort Research Station, and the Pathlow Community Pasture. It covers the advantages and disadvantages of pasture, the rationale for pasture research, forage species commonly grown for pasture, a comparison of grass species for pasture in northeast Saskatchewan, establishing a productive pasture, variations in pasture productivity, methods of balancing pasture supply to livestock demand, fertilizing and the response of the various grasses, and the effects of grazing. Reports of trials are also included, as well as estimated productivity returns with steers and cow-calf enterprises.

Download or read book The Boreal Ecosystem written by James A. Larsen and published by Elsevier. This book was released on 2013-09-03 with total page 517 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Boreal Ecosystem presents an overview of the state of knowledge on the boreal forest region of North America, with extensive reference to the boreal regions of Europe and Asia. Initial sections of this book deal with aspects of the floristic composition and evolutionary history of the boreal vegetation. These introduce subsequent discussions on the processes at work in vegetation, soils, and the atmosphere—in short, with the boreal forest as an ecosystem, the sum total of the influences of many closely interlaced biotic and physical factors. These include not only plant species that make up the visible vegetation but also nutrients, soil, temperature, rainfall, progression of the seasons, soil microflora, arthropods, insects, and larger animals such as marten, otter, beaver, moose, caribou, bear, and wolf, and man. All are closely linked strands in the web of life, a web apart from, yet dependent on and influencing, the raw physical environment. This book should serve as an introduction and reference source to its audience: undergraduate and graduate students in the biological and ecological disciplines, research workers in these fields as well as in related areas such as soil science, agronomy, genetics, and climatology; in short, everyone with an interest in boreal ecology.
Download or read book High Plains Horticulture written by John F. Freeman and published by University Press of Colorado. This book was released on 2008-11-30 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: High Plains Horticulture explores the significant, civilizing role that horticulture has played in the development of farmsteads and rural and urban communities on the High Plains portions of Colorado, Kansas, Nebraska, South Dakota, and Wyoming, drawing on both the science and the application of science practiced since 1840. Freeman explores early efforts to supplement native and imported foodstuffs, state and local encouragement to plant trees, the practice of horticulture at the Union Colony of Greeley, the pioneering activities of economic botanists Charles Bessey (in Nebraska) and Aven Nelson (in Wyoming), and the shift from food production to community beautification as the High Plains were permanently settled and became more urbanized. In approaching the history of horticulture from the perspective of local and unofficial history, Freeman pays tribute to the tempered idealism, learned pragmatism, and perseverance of individuals from all walks of life seeking to create livable places out of the vast, seemingly inhospitable High Plains. He also suggests that, slowly but surely, those that inhabit them have been learning to adjust to the limits of that fragile land. High Plains Horticulture will appeal to not only scientists and professionals but also gardening enthusiasts interested in the history of their hobby on the High Plains.

Download or read book Factors Affecting Duck Nesting in the Aspen Parklands written by David William Howerter and published by . This book was released on 2003 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: Habitat fragmentation often has been cited as a cause for reduced reproductive success of grassland-nesting birds, including ducks, though results of many studies have been equivocal. As remotely sensed habitat data become increasingly available, an increased understanding of how habitat configurations affect demographic parameters will allow wildlife managers to make better decisions about habitat preservation and restoration. We used duck (Anas spp.) nesting data from 15 65-km2 study areas (n=6300 nests) dispersed throughout the aspen (Populus tremuloides) parklands of south-central Canada, to test hypotheses and build models that predict hatching rates and nest-site distributions in relation to landscape features. We constructed separate models using landscape features generated at 3 different spatial extents and using 3 different habitat classification schemes. Generalized linear mixed-modeling techniques were used to model hatching rates, and logistic regression was used to discr.
