Download or read book Tilapias Biology and Exploitation written by M.C.M Beveridge and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 517 pages. Available in PDF, EPUB and Kindle. Book excerpt: Referred to in the Bible, pictured on the wall-friezes of ancient Egyptian tombs, and a subject of fascination for generations of scientists, the tilapias (Cichlidae: Tilapiini) have featured in the diet and culture of humankind for thousands of years. The present century has seen their spread from Africa throughout the tropics and sub-tropics, largely for food and fisheries purposes. This book attempts to pull together our knowledge of this important group - their biology and fisheries and aquaculture - in a single volume, something that has not been done comprehensively for nearly two decades. A succession of chapters by acknowledged authorities covers evolution, phylogenetic relationships and biogeography, reproductive biology, mating systems and parental care, diet, feeding and digestive physiology, environmental physiology and energetics, the role of tilapias in ecosystems, population dynamics and management, genetics, seed production, nutrition, farming, economics and marketing. The book is aimed at biologists, fisheries scientists, aquaculturists, and all interested in aquatic ecology.
Download or read book Biological Invasions and Its Management in China written by Fanghao Wan and published by Springer. This book was released on 2017-04-25 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book discusses invasive-species problems in agriculture, forests and aquatic ecosystems, highlighting the invasive mechanisms and management of the selected invasive species. Biological invasion has become a serious global ecological and economic problem that deserves particular attention from both government officials and scientists. This volume focuses on three key scientific areas: 1) population establishment and spreading mechanisms of the selected invasive species; 2) ecology adaptation, population growth, expansion and evolution of invasive species; and 3) impact of bio-invasion on the ecosystem structure and function at community and ecosystem levels. The presented research will result in techniques for better management of invasive species.
Download or read book Improving Biosecurity Through Prudent and Responsible Use of Veterinary Medicines in Aquatic Food Production written by Melba G. Bondad-Reantaso and published by Food & Agriculture Organization of the UN (FAO). This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dramatic intensification and diversification of global aquaculture has made aquaculture an important food-producing sector, providing an essential source of aquatic protein for a growing human population. The sector is recognised as creator of jobs and an important source of foreign export earnings for both developed and developing countries. However, the expanded global movements of live aquatic animals have been accompanied by the transboundary spread of a wide variety of pathogens necessitating the routine use of veterinary medicines to prevent and treat disease outbreaks, assure healthy stocks and maximise production. The use of appropriate antimicrobial treatments is one of the most effective management responses to such emergencies, but their inappropriate use can lead to increased frequency of bacterial resistance, potential transfer of resistance genes in bacteria from the aquatic environment to other bacteria, and the occurrence of bacterial residues in aquaculture products resulting in bans by importing countries. The FAO/AAHRI Expert Workshop on Improving Biosecurity through Prudent and Responsible Use of Veterinary Medicines in Aquatic Food Production was convened in Bangkok, Thailand, from 15 to 18 December 2009, to understand the current status of the use of antimicrobials in aquaculture, and to discuss the concerns and impacts of their irresponsible use on human health, the aquatic environment and trade. The discussions became the basis for drafting recommendations targeted at government and private sectors, and for developing guiding principles on the responsible use of antimicrobials in aquaculture to be considered as part of future FAO Code of Conduct for Responsible Fisheries (CCRF) Technical Guidelines for Responsible Fisheries on Prudent and Responsible Use of Veterinary Medicines in Aquaculture. Part 1 of this publication contains 15 technical background papers presented during the expert workshop, contributed by 29 specialists. Part 2 contains the highlights of the expert workshop. Because aquaculture is expected to continue to increase its contribution to the world's production of aquatic food, offer opportunities to alleviate poverty, increase employment and community development, and reduce overexploitation of natural aquatic resources, appropriate guidance to aquaculture stakeholders on the responsible use of veterinary medicines has become essential. Safe and effective veterinary medicines need to be available for efficient aquaculture production, and their use should be in line with established principles on prudent use to safeguard public and animal health. The use of such medicines should be part of national and on-farm biosecurity plans and in accordance with an overall national policy for sustainable aquaculture.
Download or read book Research Techniques in Animal Ecology written by Luigi Boitani and published by Columbia University Press. This book was released on 2000-06-01 with total page 668 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present biodiversity crisis is rife with opportunities to make important conservation decisions; however, the misuse or misapplication of the methods and techniques of animal ecology can have serious consequences for the survival of species. Still, there have been relatively few critical reviews of methodology in the field. This book provides an analysis of some of the most frequently used research techniques in animal ecology, identifying their limitations and misuses, as well as possible solutions to avoid such pitfalls. In the process, contributors to this volume present new perspectives on the collection, analysis, and interpretation of data. Research Techniques in Animal Ecology is an overarching account of central theoretical and methodological controversies in the field, rather than a handbook on the minutiae of techniques. The editors have forged comprehensive presentations of key topics in animal ecology, such as territory and home range estimates, habitation evaluation, population viability analysis, GIS mapping, and measuring the dynamics of societies. Striking a careful balance, each chapter begins by assessing the shortcomings and misapplications of the techniques in question, followed by a thorough review of the current literature, and concluding with possible solutions and suggested guidelines for more robust investigations.
Download or read book Renewable Energy and Wildlife Conservation written by Christopher E. Moorman and published by JHU Press. This book was released on 2019-09-10 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: Brings together disparate conversations about wildlife conservation and renewable energy, suggesting ways these two critical fields can work hand in hand. Renewable energy is often termed simply "green energy," but its effects on wildlife and other forms of biodiversity can be quite complex. While capturing renewable resources like wind, solar, and energy from biomass can require more land than fossil fuel production, potentially displacing wildlife habitat, renewable energy infrastructure can also create habitat and promote species health when thoughtfully implemented. The authors of Renewable Energy and Wildlife Conservation argue that in order to achieve a balanced plan for addressing these two crucially important sustainability issues, our actions at the nexus of these fields must be directed by current scientific information related to the ecological effects of renewable energy production. Synthesizing an extensive, rapidly growing base of research and insights from practitioners into a single, comprehensive resource, contributors to this volume • describe processes to generate renewable energy, focusing on the Big Four renewables—wind, bioenergy, solar energy, and hydroelectric power • review the documented effects of renewable energy production on wildlife and wildlife habitats • consider current and future policy directives, suggesting ways industrial-scale renewables production can be developed to minimize harm to wildlife populations • explain recent advances in renewable power technologies • identify urgent research needs at the intersection of renewables and wildlife conservation Relevant to policy makers and industry professionals—many of whom believe renewables are the best path forward as the world seeks to meet its expanding energy needs—and wildlife conservationists—many of whom are alarmed at the rate of renewables-related habitat conversion—this detailed book culminates with a chapter underscoring emerging opportunities in renewable energy ecology.

Available in PDF, EPUB and Kindle. Book excerpt: Explores how the management of wetlands can influence carbon storage and fluxes. Wetlands are vital natural assets, including their ability to take-up atmospheric carbon and restrict subsequent carbon loss to facilitate long-term storage. They can be deliberately managed to provide a natural solution to mitigate climate change, as well as to help offset direct losses of wetlands from various land-use changes and natural drivers. Wetland Carbon and Environmental Management presents a collection of wetland research studies from around the world to demonstrate how environmental management can improve carbon sequestration while enhancing wetland health and function. Volume highlights include: Overview of carbon storage in the landscape Introduction to wetland management practices Comparisons of natural, managed, and converted wetlands Impact of wetland management on carbon storage or loss Techniques for scientific assessment of wetland carbon processes Case studies covering tropical, coastal, inland, and northern wetlands Primer for carbon offset trading programs and how wetlands might contribute The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity.Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals.

Download or read book Genetics of Sex Determination written by R.S. Verma and published by Elsevier. This book was released on 1996-04-23 with total page 387 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Genetical Theory of Natural Selection by R.A. Fisher (1930) dictated that sexual dimorphisms may depend upon a single medelian factor. This could be true for some species but his suggestion could not take off the ground as gender in Drosophila is determined by the number of X chromosomes. Technical advances in molecular biology have revived the initial thinking of Fisher and dictate that TDF or SRY genes in humans or Tdy in mice are sex determining genes. The fortuitous findings of XX males and XY female, which are generally termed sex reversal phenomenon, are quite bewildering traits that have caused much amazement concerning the pairing mechanism(s) of the pseudoautosomal regions of human X and Y chromosomes at meiosis. These findings have opened new avenues to explore further the genetic basis of sex determination at the single gene level.The aim of the fourth volume, titled Genetics of Sex Determination is to reflect on the latest advances and future investigative directions, encompassing 10 chapters. Commissioned several distinguished scientists, all pre-eminent authorities in each field to shed their thoughts concisely but epitomise their chapters with an extended bibliography. Obviously, during the past 60 years, the metoric advances are voluminous and to cover every account of genes, chromosomes, and sex in a single volume format would be a herculean task. Therefore, a few specific topics are chosen, which may be of great interest to scientists and clinicians. The seasoned scientists who love to inquire about the role of genes in sex determination should find the original work of these notable contributors very enlightening. This volume is intended for advanced students who want to keep abreast as well as for those who indulge in the search for genes of sex determination.
