Download or read book Case Studies in Food Microbiology for Food Safety and Quality written by Rosa K Pawsey and published by Royal Society of Chemistry. This book was released on 2007-10-31 with total page 491 pages. Available in PDF, EPUB and Kindle. Book excerpt: This unique book covers the key issues relating to the control and management of the most commonly occurring food borne bacteria which compromise the safety and quality of food. The 21 case studies, drawn from a wide range of sources, present real life situations in which the management of food borne pathogens failed or was at risk of failure. Each chapter contains a case study which is supported by relevant background information (such as diagrams, tables of data, etc), study questions and a subsequent feedback commentary, all of which encourage the reader to apply their knowledge. With reference to specific organisms such as E. coli, Salmonella, Listeria monocytogenes and so on, the chapters move the reader progressively from strategies for control of food borne organisms, techniques for their control, appreciating risk, through sampling criteria and acceptance, to managing risk. With the provision of real-life problems to explore, along with the opportunity to propose and justify approaches to managing food safety, this book will be welcomed as a new approach to learning not only by students and their teachers, but also by food professionals in policy-making and enforcement and the many within the food industry who are involved with the management of food safety.

Download or read book The Illegal Wildlife Trade written by Daan P. van Uhm and published by Springer. This book was released on 2016-11-15 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book the author examines the illegal wildlife trade from multiple perspectives: the historical context, the impact on the environment, the scope of the problem internationally, the sociocultural demand for illegal products, the legal efforts to combat it, and several case studies from inside the trade. The illegal wildlife trade has become a global criminal enterprise, following in the footsteps of drugs and weapons. Beyond the environmental impact, financial profits from the illegal wildlife trade often fund organized crime groups and violent gangs that threaten public safety and security in myriad ways. This innovative volume covers several key questions surrounding the wildlife trade: why is there a demand for illegal wildlife products, which actors are involved in the trade, how is the business organized, and what are the harmful consequences. The author performed ethnographic fieldwork in three key markets: Russia, Morocco, and China, and has constructed a detailed picture of how the wildlife trade operates in these areas. Conversations with informants directly involved in the illegal business ensure unique insights into this lively black market. In the course of his journey the author follows the route of the illegal wildlife trade from poor poaching areas to rich business districts where corrupt officials, legally registered companies, wildlife farms and sophisticated criminal organizations all have a share. A fascinating look inside the world of poachers, smugglers and traders.

Download or read book Endangered Animals written by Brian Miller and published by Bloomsbury Publishing USA. This book was released on 2000-09-30 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: Explore the multiple issues that surround species declines and conservation efforts through the only reference source to examine the conflicting conservation issues of 49 endangered species. While the causes of endangerment are relatively easy to understand, the ultimate or underlying factors are often far more complex and difficult to address. An introduction to these issues and how to resolve them is provided in this unique collection of case studies of animal species that have been pushed to the brink of extinction. Each case study provides the following information: - Common name - Scientific name - Order - Family - Status - Threats - Habitat - Distribution - Natural history - Conflicting Issues - Future and Prognosis. Conservationists are increasingly recognizing that the ultimate causes of extinction are primarily socio-economic and political, yet biological approaches to recovery continue to dominate. More inclusive, interdisciplinary conservation programs are explored here to offer better prospects for managing problems and conflicts. In addition to the case studies, trends and common themes are explored to provide a comprehensive, interdisciplinary approach to conservation. Students and teachers can explore a wide variety of endangered species programs and the conflicting issues common to recovery efforts, which will enable them to evaluate conservation practice and to draw their own conclusions for improvement.

Download or read book Biology Conservation and Sustainable Development of Sturgeons written by Ramón Carmona and published by Springer Science & Business Media. This book was released on 2008-11-09 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sturgeons are considered “living fossils”, sharing many morphological and biological features with ancestral fish. Furthermore, sturgeons are of the utmost interest from an economic perspective, not only for the caviar but for the flesh. However, the wild populations of the majority of the species are at serious risk of extinction all over the world. So, it is urgent to develop strategies for both farming culture and conservation and recovery in natural habitats. This book provides a comprehensive view of the biology and sustainable development of sturgeons putting emphasis on the Southern Europe autochthonous species such as Acipenser nacarii and Acipenser sturio that share geographical distribution. Other relevant species (such as Huso huso, A. oxyrhinchus, A. ruthenus, A. stellatus) and areas (Germany, Russia, North America) are also considered. The contents are organised in three sections: Taxonomy and Biogeography (including the morphological and genetic analyses that clarify the taxonomy and phylogeny of sturgeons, focused on those from Southern Europe), Biology and Aquaculture (where several aspects of the developmental biology, feeding, and reproduction are considered in relation to the improvement of sturgeon farming), and Recovery and Conservation (that collates and analyses different recovery research actions, the ecology of the rivers for restoration as well as the problems related to the trade of caviar).

Download or read book Ecosystem Services in Azerbaijan written by Rovshan Abbasov and published by Springer Nature. This book was released on 2022-08-22 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book aims to draw readers' attention to the benefits once present nature in Azerbaijan. Over the past hundred years, much of this has been lost because of the neglect of the intrinsic values of nature by both managers and local authorities, and the overuse of natural resources. For example, oil pollution and overfishing in the Caspian Sea have almost destroyed its fish and caviar resources. In this volume, the authors distinguish between the concepts of "gain" and "income" and show readers that short-term benefits based solely on monetary income deprive people and nature itself of long-term, lasting value. The book provides readers with real historical information, discusses the interactions between humans and nature, and shows, with real data and trends, the consequences of anthropogenic activity on natural resources in Azerbaijan. The authors cover fish, water, forest, mountain, and pasture ecosystems, draw attention to the impacts that pollution and other forms of environmental degradation have had on these resources, and the show the impact that resource depletion on people’s livelihoods. The book is intended primarily for managers, policymakers, students, and academics, and will be of interest to natural scientists, historians, and students of culture.

Download or read book Sex Control in Aquaculture written by Hanping Wang and published by John Wiley & Sons. This book was released on 2018-11-08 with total page 888 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive resource that covers all the aspects of sex control in aquaculture written by internationally-acclaimed scientists Comprehensive in scope, Sex Control in Aquaculture first explains the concepts and rationale for sex control in aquaculture, which serves different purposes. The most important are: to produce monosex stocks to rear only the fastest-growing sex in some species, to prevent precocious or uncontrolled reproduction in other species and to aid in broodstock management. The application of sex ratio manipulation for population control and invasive species management is also included. Next, this book provides detailed and updated information on the underlying genetic, epigenetic, endocrine and environmental mechanisms responsible for the establishment of the sexes, and explains chromosome set manipulation techniques, hybridization and the latest gene knockout approaches. Furthermore, the book offers detailed protocols and key summarizing information on how sex control is practiced worldwide in 35 major aquaculture species or groups, including fish and crustaceans, and puts the focus on its application in the aquaculture industry. With contributions from an international panel of leading scientists, Sex Control in Aquaculture will appeal to a large audience: aquaculture/fisheries professionals and students, scientists or biologists working with basic aspects of fish/shrimp biology, growth and reproductive endocrinology, genetics, molecular biology, evolutionary biology, and R&D managers and administrators. This text explores sex control technologies and monosex production of commercially-farmed fish and crustacean species that are highly in demand for aquaculture, to improve feed utilization efficiency, reduce energy consumption for reproduction and eliminate a series of problems caused by mixed sex rearing. Thus, this book: Contains contributions from an international panel of leading scientists and professionals in the field Provides comprehensive coverage of both established and new technologies to control sex ratios that are becoming more necessary to increase productivity in aquaculture Includes detailed coverage of the most effective sex control techniques used in the world's most important commercially-farmed species Sex Control in Aquaculture is the comprehensive resource for understanding the biological rationale, scientific principles and real-world practices in this exciting and expanding field.

Download or read book Elasmobranch Biodiversity Conservation and Management written by Sarah L. Fowler and published by IUCN. This book was released on 2002 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Darwin Elasmobranch Biodiversity Conservation and Management project in Sabah held a three-day international seminar that included a one-day workshop in order to highlight freshwater and coastal elasmobranch conservation issues in the region and worldwide, to disseminate the result of the project to other Malaysian states and countries, and to raise awareness of the importance of considering aspects of elasmobranch biodiversity in the context of nature conservation, commercial fisheries management, and for subsistence fishing communities. These proceedings contain numerous peer-reviewed papers originally presented at the seminar, which cover a wide range of topics, with particular reference to species from freshwater and estuarine habitats. The workshop served to develop recommendations concerning the future prospects of elasmobranch fisheries, biodiversity, conservation and management. This paper records those conclusions, which highlight the importance of elasmobranchs as top marine predators and keystone species, noting that permanent damage to shark and ray populations are likely to have serious and unexpected negative consequences for commercial and subsistence yields of other important fish stocks.

Download or read book Polar Bears written by IUCN/SSC Polar Bear Specialist Group. Working Meeting and published by IUCN. This book was released on 2006 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: These proceedings provide an overview of the ongoing research and management activities on polar bears in the circumpolar arctic. Together with the previous 13 proceedings, they provide an historic record of international efforts in protecting, studying and managing polar bears. With recent documentation of how warmer arctic climate might affect the sea ice habitat of polar bears, the predictions of even warmer climate in the next decades, and documentation of effects on polar bears subpopulations, an evaluation of the red list status of polar bear subpopulations was followed by an increased conservation designation of vulnerable. In the complexity of possible interactions between climate change, local harvest, and in some areas high levels of pollutants, an increased level of international cooperation was advocated.

Download or read book Best Practice Guidelines for the Prevention and Mitigation of Conflict Between Humans and Great Apes written by Kimberley Hockings and published by IUCN. This book was released on 2009 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Executive summary: One of the challenges facing great ape conservation is the rising level of interaction between humans and great apes, and the resulting conflicts that emerge. As human populations continue to grow and human development makes deeper incursions into forest habitats, such conflicts will become more widespread and prevalent in the natural ranges of great apes, especially considering that the majority of great apes live outside protected areas. It is essential that we develop a comprehensive understanding of existing and potential conflict situations, and their current or future impacts on both great apes and humans. This will require the integration of quantitative and qualitative data on multiple aspects of human and great ape behaviour and ecology, along with a good understanding of local people's perceptions of the situation. Such knowledge can then be used to develop effective, locally-adapted, management strategies to prevent or mitigate human-great ape conflicts, whilst respecting both conservation objectives and socio-cultural-economic contexts. These guidelines outline a sequence of logical steps that should be considered prior to any form of human-great ape conflict intervention, and propose possible counter-measures to be used in the management of human-great ape conflicts.

Download or read book Best Practice Guidelines for the Re Introduction of Great Apes written by Benjamin Beck and published by IUCN. This book was released on 2007 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the website: Although the IUCN has previously established working protocols for plant and animal re-introduction, the great apes present unique challenges and concerns owing to their singular cognitive development. This prompted the Primate Specialist Group to reconsider the existing guidelines in terms of the specific needs of great apes. The resulting synthesis, representing the expert opinion of primatologists and re-introduction practitioners, is presented here as part of the series of best-practices documents. Specifically designed for rehabilitators and specialists in re-introduction, these guidelines start from the fundamental assumption that re-introductions should not endanger wild populations of great apes or the ecosystems they inhabit. Equally important is the health and welfare of the individual great apes being re-introduced, as well as the caretaker staff and the residents of the surrounding areas. The re-introduction guidelines also require that the factors which first threatened great apes in the proposed site of release have been addressed and resolved.

Download or read book An IUCN situation analysis of terrestrial and freshwater fauna in West and Central Africa written by and published by IUCN. This book was released on 2015-06-01 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: This situation analysis was undertaken to inform responses to several resolutions made at the 5th World Conservation Congress in 2012 about the plight of large vertebrates in West and Central Africa. It draws on a wide range of information to provide information on the status of these species, important sites, pressures, legislation, the effectiveness of protected areas, and both community-based incentives for conservation and institutional responses. The overriding conclusion is of substantial wildlife declines and inadequate responses to either long-standing pressures or rapidly escalating threats that have emerged in recent years.

Download or read book Best practice guidelines for the rehabilitation and translocation of gibbons written by International Union for the Conservation of Nature and Natural Resources (IUCN) and published by IUCN. This book was released on 2015-05-28 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rehabilitation and translocation programmes are increasingly becoming an important component of conservation action plans for threatened species. Translocation can help address gibbon conservation issues (gibbons are recognized as one of the most threatened primate families globally) by allowing gibbons held in captivity to be rescued, rehabilitated and then returned to the wild. These guidelines for the translocation of gibbons have been developed in collaboration with stakeholders in hylobatid conservation. This process was initiated druing a workshop on gibbon rehabilitation, reintroduction and translocation, facilitated by the IUCN SSC PSG Section on Small Apes (SSA), and the result of this process is the current document, which is based on shared knowledge and experience to date. The guidelines are designed to be a practical and useful document available for all stakeholders, with the aim of equipping field projects and decision makers with the tools for scientifically sound practice in gibbon rehabilitation and translocation.
