Adaptation and Fitness in Animal Populations
Fitness and adaptation are fundamental characteristics of plant and animal species, enabling them to survive in their environment and to adapt to the inevitable changes in this environment. This is true for both the genetic resources of natural ecosystems as well as those used in agricultural production. Extensive genetic variation exists between varieties/breeds in a species and amongst individuals within breeds. This variation has developed ...

Allelopathy in Sustainable Agriculture and Forestry
Simply put, allelopathy refers to an ecological phenomenon of plant-plant interference through release of organic chemicals (allelochemicals) in the environment. These chemicals can be directly and continuously released by the donor plants in their immediate environment as volatiles in the air or root exudates in soil or they can be the microbial degradation products of plant residues. The chemicals may interfere with survival and growth of ...

Micronutrient Deficiencies in Global Crop Production
A deficiency of one or more of the eight plant micronutrients (boron, chlorine, copper, iron, manganese, molybdenum, nickel and zinc) will adversely affect both the yield and quality of crops. Micronutrient deficiencies in crops occur in many parts of the world, at various scales (from one to millions of hectares), but differences in soil conditions, climate, crop genotypes and management, result in marked variations in their occurrence. The ...

Ecology of Coccinellidae
The book is the only scientific monograph dealing with coccinellids (i.e. ladybirds), a group of beetles which are beneficial predators of aphids, scale insects and mites, and are also one of the most popular insects. This volume is an updated and modified version of Biology of Coccinellidae (1973) 250 pp. Due to a vast increase in information, the book has become more voluminous (xvi + 464 pp. comprising 133 tables, 95 figures, 11 plates, ...
