Dam Builders: The Natural History of Beavers and Their Ponds
ISBN: 9781554553242 / Angielski / Miękka / 330 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Few animals in the world are as famous or as infamous as the beaver, and none save our species has the ability to so dramatically transform its environment. Beavers are remarkable animals. They have teeth that self-sharpen and never stop growing, and a heart that slows down and valves that close in their ears and noses when they dive. Their tail is the most multi-purpose of any animal on this planet; in addition to communication its many functions include serving as an air conditioner in summer and a food pantry in winter. From mighty moose that glean sodium from aquatic...

Agroforestry Education and Training: Present and Future: Proceedings of the International Workshop on Professional Education and Training in Agrofores
ISBN: 9789401074414 / Angielski / Miękka / 148 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Interest and initiatives in agroforestry education and training, as in other aspects of agroforestry development, have increased tremendously during the past decade. Coordination of such educational activities was initiated by the first international workshop on education in agroforestry organized by the International Council for Research in Agroforestry (ICRAF) in Decem- ber 1982, at Nairobi, Kenya. Since then, agroforestry has been incorporated into the curricula of many educational and training institutions around the world. Moreover, several institutions have developed entire academic...

Biomass Production by Fast-Growing Trees
ISBN: 9789401075572 / Angielski / Miękka / 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...

Thonner's Analytical Key to the Families of Flowering Plants
ISBN: 9789401098922 / Angielski / Miękka / 231 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. For the identification of a flowering plant the first step usually is to discover to which family it belongs. With some experience, the families commonly encountered in one's area of interest are soon known, but when dealing with specimens from other places, notably those from the vast and rich subtropics and tropics, there is much less certainty. The pertinent literature is often not readily available as it is often found only in expensive, rare or obscure books, or journals, present only in a few specialized institutes. Basically only a few keys to the families of flowering plants of the...

The Reticuloendothelial System in Health and Disease: Immunologic and Pathologic Aspects
ISBN: 9781468433029 / Angielski / Miękka / 476 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. An extraordinary development of the knowledge, concepts and biomedical applications has occurred during the past two decades in the biological sciences, including the Reticuloendothelial Sys- tem (RES). For example, it is now widely recognized that distinct classes of cells are involved in the recognition of "exogenous" invaders of the body such as microorganisms and other foreign an- tigens, as well as of "endogenous" parasites represented by trans- formed neoplastic cells and altered "self" antigens. Prominent among cell populations involved in such recognition of antigens and subsequent...

Cellular Ca2+ Regulation
ISBN: 9781475700091 / Angielski / Miękka / 273 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. This book arose from a meeting held at the University of Washington, Seattle, in July of 1986. The meeting was a satellite symposium of the XXXth International Congress of Physiological Sciences which occurred in Vancouver, canada, at that time. 2 Adjustments in the cytoplasmic Ca + concentration of cells occur in response to a variety of external signals. These fluctuations are a cen- tral component of one mechanism by which cells adapt their activities to changes in the external environment and to the requirements of whole body 2 homeostatic mechanisms. It is now clear that redistribution...

Post-Harvest Physiology and Crop Preservation
ISBN: 9781475700961 / Angielski / Miękka / 572 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Emphasis in agricultural research for many years has concen- trated on crop production. This emphasis has become more important in recent years with the realization that the population worldwide is outstripping the food supply. There is, however, another side to increasing the availability of the food supply. This simply involves preservation of the harvested crop-for human consumption. The losses incurred in harvesting, handling, transportation, storage and marketing crops have become a greater problem as the distance from the farm to the ultimate consumer increases. In the Western world...

Climate Change Impacts on Tropical Forests in Central America: An Ecosystem Service Perspective
ISBN: 9780415720809 / Angielski / Twarda / 220 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The loss of biodiversity is a major environmental problem in nearly every terrestrial ecosystem on Earth. This loss is accelerating driven by climate change, as well as by other causes including agricultural exploitation, fragmentation and degradation triggered by land use changes. The crucial issue under debate is the impact on the welfare of current and future population, and the role of humans in the exploitation of natural resources. This is of particular importance in Central America, which it is amongst the richest and most threatened biodiversity regions on the Earth, and where the...

ISBN: 9789401084697 / Angielski / Miękka / 239 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Maintaining or increasing stand productivity is the concern of forest land managers worldwide. Consequently, there is increasing interest in understanding the impact of environmental stress on productivity and the development of management strategies that ameliorate or reduce the deleterious effects. Invited scientists gathered in Fort Collins, Colorado on July 30, 1985, to present the current state of knowledge regarding the impact of environmental stress on forest stand productivity. Particular attention was given to elucidating the mode of action by which individual stress elements reduce...

A Re-Appraisal of Forestry Development in Developing Countries
ISBN: 9789400968592 / Angielski / Miękka / 178 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. This book is directed at foresters who work, or have an interest, in the developing world, and at development analysts and theorists who are concerned with the forestry sector. Most readers will be aware that in recent years, some fundamental changes in thinking about the development process in very poor countries have occurred. At one level, the underdevelopment problem has been explained as a lack of absorptive capacity, or implementation ability in very poor countries. However, it now seems that these are only symptoms of a more profound ailment in the whole economic structural and...
