Advances in Disease Vector Research
ISBN: 9781461279549 / Angielski / Miękka / 363 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. I think the reader will agree that we have attained a good balance in Volume 6 between human-or animal-host and plant-host-related topics from outstanding research scientists. In Chapter 1, Frank Collins, Susan Paskewitz, and Victoria Finnerty explore the potential of recombinant DNA technology to distinguish indi vidual species and to establish phylogenetic relationships among member species in the Anopheles gambiae species complex, which includes the principal malaria vectors. Currently, relatively little is known about these morphologically identical species that are sympatric over most of...

Advances in Soil Science: Volume 12
ISBN: 9781461279648 / Angielski / Miękka / 221 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Soil is formed from the physical and chemical weathering of rocks-processes described historically becau'se they involve eons of time-by glaciation and by wind and water transport of soil materials, which are later deposited in deltas and loessial planes. Soil undergoes further transformations over time and provides a habitat for biological life and a base for the development of civilizations. Soil is dynamic-always changing as a result of the forces of nature and particularly by the influences of man. Soil has been studied as long as history has been documented. Numerous references to soil...

Advances in Soil Science: Volume 14
ISBN: 9781461279785 / Angielski / Miękka / 196 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The study of soils today has taken on increased importance because a rapidly expanding population is placing demands on the soil never before experienced. This has led to an increase in land degradation. Land degradation is one of the most severe problems facing mankind. Volume 11 of Advances in Soil Science was devoted entirely to this critical area of soil science. From the beginning of agriculture until about 1950, increased food production came almost entirely from expanding the cropland base. Since 1950, however, the yield per unit of land area for major crops has increased dramatically....

Advances in Soil Science
ISBN: 9781461291572 / Angielski / Miękka / 228 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The world population in 1950 was 2. 5 billion and is more than 5 billion today. The agriculture community, however, has responded remarkably well to meeting the increased need for food and fiber. While the population growth during this period averaged almost 2% annually, the production of grain increased at an even faster rate. From 1950 to 1973, grain production increased 3. 1% annually, but slowed to about 2% from 1973 to 1984. There fore, as a whole, the world has more grain per capita available today than ever before. Several countries that were food importers just a few years ago are...

Methods for the Study of Pest Diabrotica
ISBN: 9781461293385 / Angielski / Miękka / 260 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Insects as a group occupy a middle ground in the biosphere between bac at one extreme, amphibians and mammals at the other. teria and viruses of insects present special problems to the The size and general nature study of entomology. For example, many commercially available instru ments are geared to measure in grams, while the forces commonly en countered in studying insects are in the milligram range. Therefore, tech niques developed in the study of insects or in those fields concerned with the control of insect pests are often unique. Methods for measuring things are common to all...

Advances in Soil Science
ISBN: 9781461295396 / Angielski / Miękka / 300 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The world population in 1930 was 2 billion. It reached 3 billion in 1960, stands at 4. 6 billion today, and is expected to reach 6 billion by the end of the century. The food and fiber needs of such a rapidly increasing population are enormous. One of the most basic resources, perhaps the most basic of all, for meeting these needs is the soil. There is an urgent need to improve and protect this resource on which the future of mankind directly depends. We must not only learn how to use the soil to furnish our immediate needs, but also ensure that the ability of the soil to sustain food...

Advances in Soil Science: Volume 4
ISBN: 9781461386148 / Angielski / Miękka / 226 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The world needs for food and fiber continue to increase. Population growth in the developing countries peaked at 2. 4 percent a year in 1965, and has fallen to about 2. 1 percent. However, in many developing countries almost half the people are under 15 years of age, poised to enter their productive and reproductive years. The challenges to produce enough food for this growing population will remain great. Even more challenging is growing the food in the areas of greatest need. Presently the world has great surpluses of food and fiber in some areas while there are devastating deficiencies in...

Respiration and Crop Productivity
ISBN: 9781461596691 / Angielski / Miękka / 215 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Respiration is a large and important component of the carbon economy of crops. There are already several good books dealing with the biochemistry and physiol ogy of plant respiration, but there are none I know of that are devoted to the rela tionship between respiration and crop productivity, although this relationship is more and more frequently being studied with both experiment and simulation. Crop physiology books do cover respiration, of course, but the treatment is limited. The purpose of the present book is to fill this void in the literature. The approach taken here is to use the...

Cultural Practices and Infectious Crop Diseases
ISBN: 9783642682681 / Angielski / Miękka / 246 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The development of a crop, and therefore its health, is always the result of interplay between biological and environmental factors, as influenced by human agency. In other words, crop health is a highly complex affair. This book is concerned with only one group of agents affecting crop health, the pathogens, and not with animal pests or direct effects of physiological or weather factors. Even within this one group, however, the interaction of causal agents with environmental and biotic factors is highly complex. No less complex is the effect of cultural practices on the crop and its health....

A Theory of Feeding and Growth of Animals
ISBN: 9783642683329 / Angielski / Miękka / 324 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Geoffrey R. Dolby, PhD One of the principal characteristics of a scientific theory is that it be falsifiable. It must contain predictions about the real world which can be put to experimental test. Another very important characteristic of a good theory is that it should take full cognisance of the literature of the discipline in which it is embedded, and that it should be able to explain, at least as well as its competitors, those experimental results which workers in the discipline accept without dispute. Readers of John Parks' book will be left in no doubt that his theory of the feed ing...
