Book Description
The chapters in this volume of "Insights from Animal Reproduction" address several, particular hot topics in the field of reproduction. The book begins with a comprehensive overview of the cryopreservation of sheep-produced embryos. The following chapter revises the assisted reproductive techniques available for South American wild mammals. Chapter 3 presents the technical procedures necessary to produce transgenic goats. Chapter 4 provides a comprehensive revision of the major molecular determinants of litter size in prolific species. Chapter 5 examines the germ cell determinant transmission, segregation, and function using the zebrafish as a model for germ cell specification in the embryo. Chapter 6 summarizes the current understanding of the molecular and cellular mechanisms regulating the early stages of folliculogenesis. Chapter 7 examines the sperm motility regulatory proteins as a tool to enhance sperm quality in cryopreservation processes. Chapter 8 discusses contemporary knowledge on the effects of extremely low frequency magnetic fields (ELF-MF) on male reproductive function in rodents. Chapter 9 highlights the importance of the cytogenetic evaluation in searching for causes of infertility of phenotypically normal animals, as well as individuals with an abnormal sex development. The last chapter provides evidence that other uterine diseases may be hidden behind the clinical diagnosis of pyometra that in some case may have a poor outcome.

Book Description
This book provides new insights into the universality of biological systems in animal reproduction and development by a comparative study of a variety of mechanisms in animals ranging from basal invertebrates to vertebrates, including mammals. Animals accomplish genetic diversity through meiosis and fertilization, and during embryogenesis animals must produce specialized cell types, including germ cells, in accordance with their individual body plan. This series of phenomena is essential to the continuity of life in the animal kingdom, and animals show various reproductive and developmental strategies. This volume, comprising four parts, reviews animal kingdom diversity, including reproductive strategies and germ cell differentiation mechanisms (Part 1), sex determination and differentiation (Part2), the mechanisms of fertilization (Part 3), and body axis formation (Part 4). Readers will find descriptions of the reproduction or development of 180 species, 13 phyla, 35 classes, 74 orders, 117 families, and 151 genera in this book. Of particular interest is the diversity of molecules and mechanisms used to achieve the same biological purpose in different animals. Undergraduates, graduate students, and professional scientists who want a deeper understanding of animal reproductive and developmental mechanisms will find this book to be of great value.

Book Description
The biological process through which an individual organism is produced from its parents is termed as reproduction. Animals can reproduce both sexually and asexually with sexual reproduction being more common. Parthenogenesis and ZW sex-determination system are some common asexual techniques observed in animal phyla. Sexual reproduction involves the production of haploid gametes. Smaller, motile gametes are called spermatozoa. While the larger non-motile gametes are called ova. These gametes fuse to form zygote which then develops into a new organism. This book includes some of the vital pieces of work being conducted across the world, on various topics related to animal reproduction. The various studies that are constantly contributing towards advancing technologies and evolution of this field are examined in detail. This book is a vital tool for all researching or studying animal reproduction as it gives incredible insights into emerging trends and concepts.

Book Description
Reproduction is the process of producing offspring of the same kind. Reproduction in animals can be either sexual or asexual reproduction. Sexual reproduction is the process wherein the male and female gametes fuse together to form a new individual. This process involves fertilization which can be internal or external. Internal fertilization takes place inside the body of the female whereas external fertilization takes place outside the body of the female. Asexual reproduction is the process in which a new individual is formed by the involvement of a single parent. The offspring produced are genetically and morphologically identical to the parent. Asexual reproduction occurs in unicellular organisms. The cells are divided by mitotic division and no fertilization takes place. It includes binary fission, budding, fragmentation, regeneration, parthenogenesis. This book elucidates the concepts and innovative models around prospective developments in relation to animal reproduction. Different approaches, evaluations, methodologies, and advanced studies on this topic have been included in it. This book is a vital tool for all researching or studying animal reproduction as it gives incredible insights into emerging trends and concepts.

Book Description
Reproductive skew is the study of how reproduction is partitioned in animal societies. In many social animals reproduction is shared unequally and leads to a reproductive skew among group members. Skew theory investigates the genetic and ecological factors causal to the partitioning of reproduction in animal groups and may yield fundamental insights into the evolution of animal sociality. This book brings together new theory and empirical work, mostly in vertebrates, to test assumptions and predictions of skew models. It also gives an updated critical review of skew theory. The team of leading contributors cover a wide range of species, from insects to humans, and discuss both ultimate (evolutionary) and proximate (immediate) factors influencing reproductive skew. Academic researchers and graduate students alike with an interest in evolution and sociality will find this material stimulating and exciting.
