Book Synopsis Plant Reproductive Ecology : Patterns and Strategies by : Jon and Lesley Lovett-Doust Professor of Biology the University of Windsor
Download or read book Plant Reproductive Ecology : Patterns and Strategies written by Jon and Lesley Lovett-Doust Professor of Biology the University of Windsor and published by Oxford University Press, USA. This book was released on 1988-07-07 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: This collection of reviews by leading investigators examines plant reproduction and sexuality within a framework of evolutionary ecology, providing an up-to-date account of the field. The contributors discuss conceptual issues, showing the importance of sex allocation, sexual selection and inclusive fitness, and the dimensions of paternity and maternity in plants. The evolution, maintenance, and loss of self-incompatibility in plants, the nature of 'sex choice' in plants, and sex dimorphism are all explored in detail. Specific forms of biotic interactions shaping the evolution of plant reproductive strategy are discussed, and a taxonomically based review of the reproductive ecology of non-angiosperm plant groups, such as bryophytes, ferns, and algae, is presented. Together these studies focus on the complexities of plant life cycles and the distinctive reproductive biologies of these organisms, while showing the similarities between nonflowering plants and the more thoroughly documented flowering species.

Book Synopsis Reproductive Ecology of Flowering Plants: Patterns and Processes by : Rajesh Tandon
Download or read book Reproductive Ecology of Flowering Plants: Patterns and Processes written by Rajesh Tandon and published by Springer Nature. This book was released on 2020-08-07 with total page 413 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sexual reproduction is the predominant mode of perpetuation for flowering plant species. Investigating the reproductive strategies of plants has grown to become a vast area of research and, in crop plants, covers events from flowering to fruit and seed development; in wild species, it extends up to seed dispersal and seedling recruitment. Thus, reproduction determines the extent of yield in crop plants and, in wild plants, also determines the efficacy of recruiting new adults to the population, making this field important both from fundamental and applied plant biology perspectives. Moreover, in light of the growing concerns regarding food and nutritional security for the growing population and preserving biological diversity, reproductive biology of flowering plants has acquired special significance. Extensive studies on various facets of reproduction are being carried out around the world. However, these studies are scattered across research journals and reviews from diverse areas of biology. The present volume covers the whole spectrum of reproductive ecology, from phenology and floral biology, to sexuality and pollination biology/ecology including floral rewards, breeding systems, apomixis and seed dispersal. In turn, transgene flow, its biosafety and mitigation approaches, and the ‘global pollinator crisis’, which has become a major international concern in light of the urgent need to sustain crop yield and biodiversity, are discussed in detail. Given its scope, the book offers a valuable resource for students, teachers and researchers of botany, zoology, ecology, agriculture and forestry, as well as conservation biologists.

Book Synopsis Offspring by : National Research Council
Download or read book Offspring written by National Research Council and published by National Academies Press. This book was released on 2003-05-04 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite recent advances in our understanding of the genetic basis of human behavior, little of this work has penetrated into formal demography. Very few demographers worry about how biological processes might affect voluntary behavior choices that have demographic consequences even though behavioral geneticists have documented genetics effects on variables such as parenting and divorce. Offspring: Human Fertility Behavior in Demographic Perspective brings together leading researchers from a wide variety of disciplines to review the state of research in this emerging field and to identify promising research directions for the future.
Download or read book Drosophila written by Therese A. Markow and published by Elsevier. This book was released on 2005-11-01 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: Anyone wishing to tap the research potential of the hundreds of Drosophila species in addition to D.melanogaster will finally have a single comprehensive resource for identifying, rearing and using this diverse group of insects. This is the only group of higher eukaryotes for which the genomes of 12 species have been sequenced.The fruitfly Drosophila melanogaster continues to be one of the greatest sources of information regarding the principles of heredity that apply to all animals, including humans. In reality, however, over a thousand different species of Drosophila exist, each with the potential to make their own unique contributions to the rapidly changing fields of genetics and evolution. This book, by providing basic information on how to identify and breed these other fruitflies, will allow investigators to take advantage, on a large scale, of the valuable qualities of these other Drosophila species and their newly developed genomic resources to address critical scientific questions.* Provides easy to use keys and illustrations to identify different Drosophila species* A guide to the life history differences of hundreds of species* Worldwide distribution maps of hundreds of species* Complete recipes for different Drosophila diets* Offers an analysis on how to account for species differences in designing and conducting experiments* Presents useful ideas of how to collect the many different Drosophila species in the wild
Book Synopsis Asdell's Patterns of Mammalian Reproduction by : Virginia Douglass Hayssen
Download or read book Asdell's Patterns of Mammalian Reproduction written by Virginia Douglass Hayssen and published by Cornell University Press. This book was released on 1993 with total page 1036 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the appearance of the second edition of Sydney A. Asdell's widely used Patterns of Mammalian Reproduction in 1964, the field of reproductive physiology has expanded dramatically. Accordingly, this revision adopts a different structure from previous editions, substituting empirical delineations for physiological interpretations. With the emphases now on a presentation of the published facts of mammalian reproduction, it provides a thorough compilation of what is known about the basic reproductive biology of each of the 4300 mammalian species.To gather information, the authors examined more than 20,000 publications, dating up to 1992. They used primary sources as much as possible, supplementing them with English translations of Russian, Finnish, Chinese, and Japanese journals. The data are presented in taxonomic order. Each familial account summarizes the pattern of reproduction for the family and provides lists of citations arranged by topic of the literature on the endocrinology, reproductive anatomy, and reproductive physiology of the family. Following each account is a tabular listing of species-specific data for neonatal mass and size, weaning mass and size, litter size, age at sexual maturity, estrous cycle length, gestation length, lactation length, number of litters per year, and seasonality of reproduction. For each of these reproductive variables, the range of data gleaned from the literature is given, together with the source of each value listed.Virginia Hayssen is Assistant Professor of Biology at Smith College. Ari Van Tienhoven is Professor of Animal Physiology, Emeritus, at Cornell University. Ans Van Tienhoven assisted in the compilation of data for the book.

Book Synopsis Hormones and Reproduction in Fishes, Amphibians, and Reptiles by : David O. Norris
Download or read book Hormones and Reproduction in Fishes, Amphibians, and Reptiles written by David O. Norris and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 627 pages. Available in PDF, EPUB and Kindle. Book excerpt: Comparative endocrinology is one of the most rapidly developing subdis ciplines within the field of endocrinology, and it is having a significant impact on research at the molecular, cellular, organisma1 and environmental levels. Much of the current ferment in endocrinology is in reproductive endocrinology. The purpose of this volume on hormones and reproduction in fishes, amphibians and reptiles is to summarize our present understandings and to identify important research problems to be addressed in the area of comparative reproductive endocrinology. It was inspired by the gathering at Copper Mountain, Colorado, of eminent endocrine scientists from around the world on the occasion of the Tenth International Symposium on Comparative Endocrinology in July, 1985. While preparing for that meeting, we decided that a special volume on reproductive endocrinology was needed to summarize what is known and to stimulate research in particular directions. Why do we emphasize fishes, amphibians and reptiles? First, knowledge about the reproductive endocrinology of these ectothermic vertebrates can provide a clearer picture of the evolution of reproductive hormones and their effects on target organs. This comparative approach can lead to new theories about the evolution of reproductive control mechanisms. Second, studies concerning the reproductive endocrinology of "lower" vertebrates can result in development of "model systems" for application to studies of birds and mammals. Indeed, information about the patterns of reproductive control in ectothermic vertebrates can tell us which are evolutionarily stable and which are labile.

Book Synopsis Male Fertility Patterns and Determinants by : Li Zhang
Download or read book Male Fertility Patterns and Determinants written by Li Zhang and published by Springer Science & Business Media. This book was released on 2010-11-19 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses the biological, methodological and sociological issues that have caused men to be overlooked in demographic and sociological literature of fertility. It explores the patterns and determinants of male fertility and studies male fertility rates as compared to those of females in 43 countries and places, over time. Data used in the aggregate level analysis come from multiple sources, including the 2001 United Nations Demographic Yearbook, the 1964 to 2004 Taiwan-Fukien Demographic Yearbooks, and National Statistics Reports by the Statistics Bureau of Republic of China. To explore male fertility determinants, the book analyzes individual data from the 2002 National Survey of Family Growth (NSFG) in the United States. The findings presented here demonstrate that male fertility differs from female fertility in both rates and determinants, which suggests that female fertility cannot fully represent human fertility.
