Book Description
Many mites possess extremely intricate life styles in close association with plant and animal hosts. Their polymorphism has made classification a challenge, and their ability to reproduce both sexually and asexually has made efforts to control their populations difficult. This, however, has given rise to theories to explain the origin and function of sexual reproduction in general. In numbers of species and geographic distribution, mites may even surpass the insects. In soils, they are a major component in the system for cycling nutrients. Unlike insects, they have invaded the marine environment. These and a number of other topics are explored in Mites. Because of their extremely small size, mites have been ignored during the development of major evolutionary and ecological theories. Yet mites routinely violate fundamental concepts such as heterochrony, sexual selection, the evolution of sex ratio, and ontogeny. Recent research methodologies have made it practical for the first time to perform experimental work with mites, and since they offer short generation times and rapid research results, they are excellent model systems. Mites announces these results and should appeal to professionals in entomology, acarology, ecology, population genetics, and evolutionary biology.

Book Description
Arthropods are important to worldwide agriculture, food safety, human health, and energy production. Besides their practical significance, various species represent excellent model systems for biological investigations of evolution, development, physiology, reproduction, and social interaction. For these reasons, arthropod genomics is receiving inc

Book Description
Spider Evolution: Genetics, Behavior, and Ecological Influences provides a thorough exploration of the evolutionary trail of arachnids, particularly spider species, from prehistoric origins to current sustainability issues. This book analyzes extinct organisms in the Arachnida class, specifically looking at their phylogenomics and molecular footprints to understand evolutionary changes in diversification in today's species. Sections cover spider origins and their influences on behavioral traits, physiology of sensory organs, and biomechanics, also touching on spiders as prey and predators and how their roles have changed in the 400 million years of Arachnida existence. The book then focuses upon current environmental issues facing spider species and how these have, and can, affect the evolution of these organisms. Topics include biodiversity minimization, climate change and natural disasters. This book is a much-needed resource for entomologists and arachnid- or arthropod-driven researchers. Advanced undergraduate and graduate students will also benefit from the historic review, current assessment and future predictions of spider evolution provided in this book. - Provides a complete view of spider species from their first fossil evidence nearly 400 million years ago - Focuses on climate change and biodiversity threats as environmental factors currently affecting these organisms - Contains the most up-to-date knowledge on evolutionary genetics, physiology changes and behavioral outcomes

Book Description
An introductory discussion of basic chromosome structure and function preceeds the main text on the application of cytogenetic approaches to the analysis of the manipulation of both the genetic make-up and the genetic transmission system of plant breeding material. Analysis using light and electron microscopy, segregations and molecular techniques, yields information for assessing the material before and after manipulation. Much attention is given to quantitative methods. Manipulation not only involves the construction of specific genotypes, but also chromosomal transmission systems. Although analysis and manipulation in the somatic cycle are considered, the focus is on the generative cycle, with emphasis on analysis and subsequent segregation of specifically constructed material. The book is intended for plant breeders and other scientists interested in the analysis and manipulation of breeding material at the chromosomal level. Comparisons with molecular and cell biological approaches are made, and the potential of the various methods is evaluated.

Book Description
It was at the end of the 19th century that a Swiss biologist, Karl Nageli first proposed the existence of hereditary organelles that carried information from parent to offspring. Ensuing decades experienced vigorous studies that led to the development of discovery that chromosomes are indeed the carriers of genetic information. Subsequent studies, especially by Morgan and Bridges, established unequivocally the chromosome theory of inheritance. Today, the structure of chromosome is well established. At the physical level, eukaryotic chromosomes are composed of a single, linear, double helix of DNA. The elementary helical structure involves nucleosomes, comprised of histones around which the DNA is wrapped. A hierarchy of higher order of chromosomal architecture may possibly be responsible for the regulation of gene helical structures expression. The localized condensations of DNA constitute chromomeres. Uncoiled structures sometimes extending from chromomeres, which form loops, is the result of discontinuities in the regular coiling of the DNA in the chromosome.
