Available in PDF, EPUB and Kindle. Book excerpt: Fisheries supply a critically important ecosystem service by providing over three billion people with nearly 20% of their daily animal protein intake. Yet one third of the world's fish stocks are currently harvested at unsustainable levels. Calls for the adoption of more holistic approaches to management that incorporate broader ecosystem principles are now being translated into action worldwide to meet this challenge. The transition from concept to implementation is accompanied by the need to further establish and evaluate the analytical framework for Ecosystem-Based Fishery Management (EBFM). The objectives of this novel textbook are to provide an introduction to this topic for the next generation of scientists who will carry on this work, to illuminate the deep and often underappreciated connections between basic ecology and fishery science, and to explore the implications of these linkages in formulating management strategies for the 21st century. Fishery Ecosystem Dynamics will be of great use to graduate level students as well as academic researchers and professionals (both governmental and NGO) in the fields of fisheries ecology and management.

Available in PDF, EPUB and Kindle. Book excerpt: Continuing concern about water supply and quality, ecosystem sustainability and restoration demands that the modern approach to the management of lakes and reservoirs should be based on a sound understanding of the application of the scientific and ecological principles that underlie freshwater processes. The Lakes Handbook provides an up-to-date overview of the application of ecologically sound approaches, methods and tools using experience gained around the world for an understanding of lakes and their management. Volume one of the Handbook addresses the physical and biological aspects of lakes pertinent to lake management, emphasising those aspects particularly relevant to large, still bodies of water. Volume two then considers lake management, with particular emphasis on sustainability, restoration and rehabilitation. This handbook will be invaluable to ecologists, environmental scientists, physical geographers and hydrologists involved in limnological research, as well as advanced undergraduate and graduate students looking for authoritative reviews of the key areas of limnological study. Brings together basic science and management issues. International coverage and international authors. Reviews management issues at a level suitable for the non-expert.

Book excerpt: Inland aquatic habitats occur world-wide at all scales from marshes, swamps and temporary puddles, to ponds, lakes and inland seas; from streams and creeks to rolling rivers. Vital for biological diversity, ecosystem function and as resources for human life, commerce and leisure, inland waters are a vital component of life on Earth. The Encyclopedia of Inland Waters describes and explains all the basic features of the subject, from water chemistry and physics, to the biology of aquatic creatures and the complex function and balance of aquatic ecosystems of varying size and complexity. Used and abused as an essential resource, it is vital that we understand and manage them as much as we appreciate and enjoy them. This extraordinary reference brings together the very best research to provide the basic and advanced information necessary for scientists to understand these ecosystems – and for water resource managers and consultants to manage and protect them for future generations.

This book was released on 2017-03-15 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aquatic microorganisms are tidily related to the carbon cycle in aquatic systems, especially in respect to its accumulation and emission to atmosphere. In one hand, the autotrophs are responsible for the carbon input to the ecosystems and trophic chain. On the other hand, the heterotrophs traditionally play a role in the carbon mineralization and, since microbial loop theory, may play a role to carbon flow through the organisms. However, it is not yet clear how the heterotrophs contribute to carbon retention and emission especially from tropical aquatic ecosystems. Most of the studies evaluating the role of microbes to carbon cycle in inland waters were performed in high latitudes and only a few studies in the tropical area. In the prospective of global changes where the warm tropical lakes and rivers become even warmer, it is important to understand how microorganisms behave and interact with carbon cycle in the Earth region with highest temperature and light availability. This research topic documented microbial responses to natural latitudinal gradients, spatial within and between ecosystems gradients, temporal approaches and temperature and nutrient manipulations in the water and in the sediment.

Download or read book Deep-sea Food Chains and the Global Carbon Cycle written by Gilbert T. Rowe and published by Springer Science & Business Media. This book was released on 1992 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carbon dioxide and other greenhouse gases are increasing in the atmosphere due to the burning of fossil fuels, the destruction of rain forests, etc, leading to predictions of a gradual global warming which will perturb the global biosphere. An important process which counters this trend toward potential climate change is the removal of carbon dioxide from the surface ocean by photosynthesis. This process packages carbon in phytoplankton which enter the food chain or sink into the deep sea. Their ultimate fate is a rain or organic debris out of the surface-mixed layer of the ocean. On a global scale, the mechanisms and overall rate of this process are relatively little known.

Download or read book Littoral Structure as a Driver of Food Chain Length in Lakes written by Jacob Ziegler and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Lakes are among the most susceptible ecosystems to anthropogenic modification as humans are drawn to freshwaters for the multitude of ecosystems services they provide. The littoral habitat structure of lakes, both in the form of aquatic vegetation (macrophytes) and coarse woody debris (CWD), is often negatively altered by direct and indirect human activities. Little is known about the effect that loss of littoral structure might have on whole lake food webs with respect to energy flow and trophic transfers. The maximum number of trophic transfers within a food web is referred to as food chain length and can control community composition through trophic cascades. Therefore, detectable changes in food chain length likely have impacts on the lake food web. I predicted that loss of littoral structure would result in reduced food chain length due to loss of refuge for intermediate consumers. I used a field study and a simulation model to (1) determine if there was a significant relationship between food chain length and littoral structure in the form of macrophytes and (2) assess the support for two different potential mechanisms (i.e. for changes in refuge or productivity) through which macrophytes and coarse woody debris could alter food chain length. The field study showed that food chain length was positively related to macrophyte abundance. The simulation model shed further insight and showed that refuge provided by macrophytes and CWD may account for observed food chain length increases due to preservation of predatory invertebrates. From these results, we can infer that the loss of littoral habitat structure likely results in a shortening of the lake food chain, which can have implications for community composition, energy flow and whole ecosystem responses to change." --
