Book Description
This book offers a sampling of cytological features and patterns as an aid to study, revision and continuing education for veterinarians in practice and training, for veterinary students, nurses, and technicians. The cases are presented randomly, are illustrated by 267 photomicrographs in full color, and appear as self-assessment questions and detailed explanatory answers. Species covered include the dog, the cat, and the horse, with additional material on the cow.

Book Description
This 1981 collection focuses on a wide range of topics in the general field of evolutionary biology. The authors have all been associated with Professor M. J. D. White, who was the world authority on chromosomal evolution and speciation, to whom this volume was presented on his seventieth birthday.

Book Description
Biology was forged into a single, coherent science only within living memory. In this volume the thinkers responsible for the "modern synthesis" of evolutionary biology and genetics come together to analyze that remarkable event. In a new Preface, Ernst Mayr calls attention to the fact that scientists in different biological disciplines varied considerably in their degree of acceptance of Darwin's theories. Mayr shows us that these differences were played out in four separate periods: 1859 to 1899, 1900 to 1915, 1916 to 1936, and 1937 to 1947. He thus enables us to understand fully why the synthesis was necessary and why Darwin's original theory--that evolutionary change is due to the combination of variation and selection--is as solid at the end of the twentieth century as it was in 1859.

Book Description
This book presents animal cytology as a science of seeing and interpreting chromosome form and behaviour, and of appreciating its evolutionary significance. Its principal objective is to help students develop a basic understanding and confidence on all matters relating to animal chromosomes.

Book Description
Sex is the queen of problems in evolutionary biology. Generations of researchers have investigated one of the last remaining evolutionary paradoxes: why sex exists at all. Given that sexual reproduction is costly from an evolutionary point of view, one could wonder why not all animals and plants reproduce asexually. Dozens of contemporary hypotheses attempt to explain the prevalence of sex and its advantages and predict the early extinction of fully asexual lineages. The major theme of this book is: what is the fate of animal and plant groups in which sex is lost? Initial chapters discuss theory behind asexual life: what major disadvantages do asexual groups have to face, what are the genetic and ecological consequences and what does this theory predict for more applied aspects of asexual life, for example in agricultural pests, diseases as well as in cultural crops such as grapes. Cases studies in many animals (focusing on both invertebrates and vertebrates) and plants reveal parallel, but also singularly novel adaptations to the absence of meiosis and syngamy. And last but not least, are asexuals really doomed to early extinction or do genuine ancient asexuals exist? This book assembles contributions from the most important research groups dealing with asexual evolution in eukaryotes. It is a milestone in research on parthenogenesis and will be useful to undergraduate as well as graduate students and to senior researchers in all fields of evolutionary biology, as the paradox of sex remains its queen of problems.
