Places of Last Resort: The Expansion of the Farm Frontier into the Boreal Forest in Canada, c. 1910-1940
ISBN: 9780773530393 / Angielski / Twarda / 264 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Tens of thousands of Canadian settlers faced the challenge of starting a farm in the near North in the 1910s, twenties, and thirties. In Places of Last Resort David Wood documents this last significant expansion of farm settlement in Canada and the often painful process of discovering that there was a limit to how far traditional farming could go. Northerly locations were desperately sought out after more accessible land further south was taken up. Wood identifies the demographic characteristics of the surging population of land-seekers, showing how some aspects echoed those of earlier...

ISBN: 9780774806831 / Angielski / Miękka / 408 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. These are turbulent, unpredictable, yet opportune times for Canadian forestry. Never before have competing demands on Canada's forest resources been so great. At the same time, we are finally being forced to confront the sustainable limit of these resources. Now, the improbable has happened: government, industry, First Nationa, and NGOs appear to be part of an emerging consensus that industrial forestry in Canada must change. The Wealth of Forests is a pioneering attempt to grapple with the policy implications of the transition to sustainable forestry. While much has been...

Biomass Production by Fast-Growing Trees
ISBN: 9780792302087 / Angielski / Twarda / 288 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Even though most of the biomass of the planet is in forests, we live in a world where wood as a raw material and its products are increasingly scarce. This is particularly so in important areas such as the European Community, which is far from self-sufficient in terms of wood. In recent years the need to intensify forest production and, in some cases, to uti lize abandoned agricultural land for forestry has focussed world-wide attention on the economic importance of fast-growing tree plantations. These are usually managed as short "rotations" (growing cycles) of less than 15 years, often for...

Predicting Breeding Values with Applications in Forest Tree Improvement
ISBN: 9780792304609 / Angielski / Twarda / 367 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. In most breeding programs of plant and animal species, genetic data (such as data from field progeny tests) are used to rank parents and help choose candidates for selection. In general, all selection processes first rank the candidates using some function of the observed data and then choose as the selected portion those candidates with the largest (or smallest) values of that function. To make maximum progress from selection, it is necessary to use a function of the data that results in the candidates being ranked as closely as possible to the true (but always unknown) ranking. Very often...

Management of Nutrition in Forests Under Stress: Proceedings of the International Symposium, Sponsored by the International Union of Forest Research O
ISBN: 9780792312468 / Angielski / Twarda / 676 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. During the 1970s and 1980s, Sitka spruce (Picea sitchensis, Bong. Carr. ) was planted extensively on northern Vancouver Island (B. C., Canada) to regenerate slashburned clearcuts previously occupied by old-growth Thuja p1icata, Donn, Tsuga heterophy11a, Raf. Sarg., and an ericaceous unders tory shrub salal (Gaul ther ia sha11on, Pursh CH sites 1 ) . The planted Sitka spruce grew well initially on these sites, but experienced nutritional stress and reduced growth 8 to 14 yr after planting (Germain, 1985; Weetman et a1., 1990a, b). Accompanying the onset of the nutritional stress was the...

In Vitro Culture of Trees
ISBN: 9780792315407 / Angielski / Twarda / 238 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Woody plants provide many challenges to the tissue culturist. Although there are many excellent tissue culture books and manuals available, these are generally strongly biased towards herbacious crops. Consequently, they often do not pay sufficient attention to the problems that specifically apply to in vitro culture of tree species. Culture of the latter often poses problems which are either absent or of lesser significance when culturing herbacious species.
When trees in the field are used as explant source, the problems can be especially severe. For example, the... Woody plants provide many challenges to the tissue culturist. Although there are many excellent tissue culture books and manuals available, these are ...

Population Genetics of Forest Trees: Proceedings of the International Symposium on Population Genetics of Forest Trees Corvallis, Oregon, U.S.A., July
ISBN: 9780792318576 / Angielski / Twarda / 423 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Tropical climates, which occur between 2330'N and S latitude (Jacob 1988), encompass a wide variety of plant communities (Hartshorn 1983, 1988), many of which are diverse in their woody floras. Within this geographic region, temperature and the amount and seasonality of rainfall define habitat types (UNESCO 1978). The F AO has estimated that there 1 are about 19 million km of potentially forested area in the global tropics, of which 58% were estimated to still be in closed forest in the mid-1970s (Sommers 1976; UNESCO 1978). Of this potentially forested region, 42% is categorized as dry...

ISBN: 9780792350354 / Angielski / Twarda / 249 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Large areas of the warm, humid tropics in Southeast Asia, the Pacific, Latin America, the Caribbean, and Africa are hilly or mountainous. Jackson and Scherr (1995) estimate that these tropical hillside areas are inhabited by 500 million people, or one-tenth of the current world population, many of whom practice subsistence agriculture. The region most affected is Asia which has the lowest area of arable land per capita. Aside from limited areas of irrigated terraces, most of the sloping land, which constitutes 60% to 90% of the land resources in many Southeast Asian countries, has been...

The Analytic Hierarchy Process in Natural Resource and Environmental Decision Making
ISBN: 9780792370765 / Angielski / Twarda / 307 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Decision making in land management involves preferential selection among competing alternatives. Often, such choices are difficult owing to the complexity of the decision context. Because the analytic hierarchy process (AHP, developed by Thomas Saaty in the 1970s) has been successfully applied to many complex planning, resource allocation, and priority setting problems in business, energy, health, marketing, natural resources, and transportation, more applications of the AHP in natural resources and environmental sciences are appearing regularly. This realization has prompted the authors to...
