Download or read book Freshwater Microplastics written by Martin Wagner and published by Springer. This book was released on 2017-11-21 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is open access under a CC BY 4.0 license. This volume focuses on microscopic plastic debris, also referred to as microplastics, which have been detected in aquatic environments around the globe and have accordingly raised serious concerns. The book explores whether microplastics represent emerging contaminants in freshwater systems, an area that remains underrepresented to date. Given the complexity of the issue, the book covers the current state-of-research on microplastics in rivers and lakes, including analytical aspects, environmental concentrations and sources, modelling approaches, interactions with biota, and ecological implications. To provide a broader perspective, the book also discusses lessons learned from nanomaterials and the implications of plastic debris for regulation, politics, economy, and society. In a research field that is rapidly evolving, it offers a solid overview for environmental chemists, engineers, and toxicologists, as well as water managers and policy-makers.
Download or read book Biological Invasions in South Africa written by Brian W. van Wilgen and published by Springer Nature. This book was released on 2020-03-10 with total page 972 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access volume presents a comprehensive account of all aspects of biological invasions in South Africa, where research has been conducted over more than three decades, and where bold initiatives have been implemented in attempts to control invasions and to reduce their ecological, economic and social effects. It covers a broad range of themes, including history, policy development and implementation, the status of invasions of animals and plants in terrestrial, marine and freshwater environments, the development of a robust ecological theory around biological invasions, the effectiveness of management interventions, and scenarios for the future. The South African situation stands out because of the remarkable diversity of the country, and the wide range of problems encountered in its varied ecosystems, which has resulted in a disproportionate investment into both research and management. The South African experience holds many lessons for other parts of the world, and this book should be of immense value to researchers, students, managers, and policy-makers who deal with biological invasions and ecosystem management and conservation in most other regions.

Download or read book Freshwater Ecology written by Gerry Closs and published by John Wiley & Sons. This book was released on 2009-04-01 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Freshwater ecosystems are under increasing pressure as human populations grow and the need for clean water intensifies. The demand for ecologists and environmental managers who are trained in basic freshwater ecology has never been greater. Students and practitioners new to the field of freshwater ecology and management need a text that provides them with an accessible introduction to the key questions while still providing sufficient background on basic scientific methods. Gerry Closs, Barbara Downes and Andrew Boulton have written a text that meets the requirements of these students. Following an introduction to scientific methodology and its application to the study of ecology, several key concepts in freshwater ecology are reviewed using a wide range of scientific studies into fundamental and applied ecological questions. Key ecological questions that are explored in a freshwater context include the role of animal dispersal and predators on freshwater community structure and the impact of pollutants and introduced species on freshwater ecosystems. This book represents the only freshwater ecology textbook that is specifically aimed at an introductory level. It will also be a useful primer for students who have not previously taken a specialized freshwater course but who require an accessible overview of the subject. General reviews on the methods of science, influence of scale, and the main features of freshwater systems. Coverage of several fundamental and applied ecological questions. A logical structure in each chapter that builds from a general observation of an ecological pattern, to an exploration of the various scientific approaches that can be used to investigate such patterns. Suggested further reading lists for each chapter.

Download or read book The Next Generation of Scientists in Africa written by Beaudry, Catherine and published by African Minds. This book was released on 2018-11-23 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: Young scientists are a powerful resource for change and sustainable development, as they drive innovation and knowledge creation. However, comparable findings on young scientists in various countries, especially in Africa and developing regions, are generally sparse. Therefore, empirical knowledge on the state of early-career scientists is critical in order to address current challenges faced by those scientists in Africa. This book reports on the main findings of a three-and-a-half-year international project in order to assist its readers in better understanding the African research system in general, and more specifically its young scientists. The first part of the book provides background on the state of science in Africa, and bibliometric findings concerning Africa’s scientific production and networks, for the period 2005 to 2015. The second part of the book combines the findings of a large-scale, quantitative survey and more than 200 qualitative interviews to provide a detailed profile of young scientists and the barriers they face in terms of five aspects of their careers: research output; funding; mobility; collaboration; and mentoring. In each case, field and gender differences are also taken into account. The last part of the book comprises conclusions and recommendations to relevant policy- and decision-makers on desirable changes to current research systems in Africa.
Download or read book Climate Change written by Mary Scholes and published by NYU Press. This book was released on 2015-11-01 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change affects us all, but it can be a confusing business. In this book, three scientists with several decades of experience in assessing the potential effects of climate change for the southern African region share their insights. Complex issues are dealt with in plain language, without oversimplification and with attention to accuracy. The material is up-to-date as is possible in such a fast-developing field. Climate Change: Briefings from Southern Africa takes the form of 55 'frequently-asked' questions', each with a brief and clear reply. It is illustrated with colour diagrams and photographs, and examples are tailored to the regional context. The authors' introduction provides an overview of current national and international policies aimed at regulating climate change. The content is divided into four sections, which take the reader through the science of how climate system works; the projected impacts in southern Africa during the twenty-first century; what this means for the South African economy and society; and what can be done to avoid harm. The briefings can be read alone or in sequence. The year 2015 is regarded as a watershed for global climate change action if a global average temperature rise of more than two degrees abbove the pre-Industrial level is to be avoided. This book provides compelling evidence that the impact on agriculture, fisheries, water resources, human health, plants and animals as well as sea levels will be dangerous. However, the book ends on a positive note by offering advice on how the world can avoid such bleak outcomes, while allowing a good life for all. The volume is aimed at interested non-scientists, including business people, decision-makers, ordinary citizens and students

Download or read book Freshwater Fisheries Ecology written by John F. Craig and published by John Wiley & Sons. This book was released on 2016-01-12 with total page 920 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inland fisheries are vital for the livelihoods and food resources of humans worldwide but their importance is underestimated, probably because large numbers of small, local operators are involved. Freshwater Fisheries Ecology defines what we have globally, what we are going to lose and mitigate for, and what, given the right tools, we can save. To estimate potential production, the dynamics of freshwater ecosystems (rivers, lakes and estuaries) need to be understood. These dynamics are diverse, as are the earths freshwater fisheries resources (from boreal to tropical regions), and these influence how fisheries are both utilized and abused. Three main types of fisheries are illustrated within the book: artisanal, commercial and recreational, and the tools which have evolved for fisheries governance and management, including assessment methods, are described. The book also covers in detail fisheries development, providing information on improving fisheries through environmental and habitat evaluation, enhancement and rehabilitation, aquaculture, genetically modified fishes and sustainability. The book thoroughly reviews the negative impacts on fisheries including excessive harvesting, climate change, toxicology, impoundments, barriers and abstractions, non-native species and eutrophication. Finally, key areas of future research are outlined. Freshwater Fisheries Ecology is truly a landmark publication, containing contributions from over 100 leading experts and supported by the Fisheries Society of the British Isles. The global approach makes this book essential reading for fish biologists, fisheries scientists and ecologists and upper level students in these disciplines. Libraries in all universities and research establishments where biological and fisheries sciences are studied and taught should have multiple copies of this hugely valuable resource. About the Editor John Craig is Editor-in-Chief of the Journal of Fish Biology and has an enormous range of expertise and a wealth of knowledge of freshwater fishes and their ecology, having studied them around the globe, including in Asia, North America, Africa, the Middle East and Europe. His particular interests have been in population dynamics and life history strategies. He is a Fellow of the Linnean Society of London and the Royal Society of Biology.
