Wetlands and Sustainability

The Wetland Book, 2016

The Wetland Book 1 is designed as a 'first port-of-call' reference work for information on the structure and functions of wetlands, current approaches to wetland management, and methods for researching and understanding wetlands. Contributions by experts summarize key concepts, orient the reader to the major issues, and support further research on such issues by individuals and multidisciplinary teams. The Wetland Book 1 is organized in three parts-Wetland structure and function; Wetland management; and Wetland methods-each of which is divided into a number of thematic sections. Each section starts with one or more overview chapters, supported by chapters providing further information and case studies on different aspects of the theme.

Wetland management in the United States has never been as challenging as in today's highly modified landscape. Initially, wetland science and management emerged as professions in response to widespread conversion of wetlands to other uses and concerns over negative impacts on wildlife populations, especially migratory birds. Consequently, wetland management was focused on wildlife, and the initial management technique was simply to protect wetlands. However, extensive conversion of lands for agricultural and urban expansion over the past 60 years has modified ecosystem processes at the landscape scale sufficiently to compromise wetland management activities on adjacent lands dedicated to conservation. Moreover, society now expects a broad suite of ecosystem services to be delivered. As a result, many previously used wetland management techniques are no longer appropriate because they do not take into account influences of adjacent land uses or other ecosystem services, such as ground-water recharge. Other early management approaches may have been ineffective because they were based on an incomplete understanding of wetland processes or social influences. Meanwhile, wetland losses continued, as well as loss of services provided by the remaining managed wetlands. Regulation starting in the 1970s and subsequent research attention on wetland functioning has led to new knowledge and a broader understanding of wetland processes and recognition of the full suite of services (e.g., water storage, water quality improvement, aquifer maintenance, climate mitigation). To be effective in today's highly modified landscape, knowledge of social choices, political influences, and dynamic wetland processes is required to meet wetland management objectives for a range of ecosystem services. We argue that adopting a process-based perspective is critical to develop strategies to optimize a suite of wetland services, including providing traditional wildlife habitat.

As a result of concern over problems associated with the future of managed wetlands in North America, nearly two dozen wetland scientists and managers met in February 2006 at Bosque del Apache National Wildlife Refuge in New Mexico and discussed a sustainable approach to wetland management. This approach links science with management by focusing on underlying wetland processes. From that meeting, several papers were developed and published in Wetlands to address these concerns (Euliss et al. 2008, Smith et al. 2008, Wilcox 2008). This article summarizes our first paper, Euliss et al. (2008). A future National Wetlands Newsletter article will summarize Smith et al. (2008). Realization of the role that complex interactions play in maintaining ecosystems, coupled with increasing demands of humans for ecosystem services, has prompted much interest in ecosystem management. Not surprisingly, sustainability of ecosystems has become an explicitly stated goal of many natural resource agencie...

A wetland is an ecological community that is inundated either year around or seasonally. Wetlands are found from the tundra to the tropics and on every continent except Antarctica. There are many kinds of wetlands and many ways to categorize them. Two general categories of wetlands are recognized namely coastal or tidal wetlands and inland or non-tidal wetlands. Wetlands are among the most productive ecosystems in the world, comparable to rain forests and coral reefs. An immense biodiversity of species of microbes, plants, insects, fish, amphibians, reptiles, birds and mammals can be part of a wetland ecosystem. Wetlands perform significant economic benefits to human society, including some ecosystem services that no other ecosystem can provide, including certain types of water quality improvement, flood protection, shoreline erosion control, and opportunities for recreation and aesthetic appreciation and natural products for our use at no cost. Protecting wetlands in turn can protect our safety and welfare. A primary intent of this article is to provide the reader with special interest in wetland delineation, wetland benefits, wetland mitigation and wetland biology. Wetlands are no more thought to be useless, disease ridden areas rather they are now considered to be an ecological boon for the environment!

This paper is about combining three E-marketing tools including Search engine Optimization, Social Media Marketing and Email marketing to develop a new multiple channel E-marketing framework. A marketing framework can be generally defined as a written document that details the current marketing situation, threats and opportunities, marketing objectives, and the strategies for achieving the objectives. A marketing plan can be written for each product, service, brand, or for the company as a whole. An e-marketing plan is more focused than the traditional marketing plan. An e-marketing plan is more focused comparing to the traditional marketing plan. Although it often includes some topics that are used in traditional marketing plan too and it is more centered on the marketing opportunities, threats, objectives and strategies on the Internet. Having an effective online marketing framework is the most important part of marketing strategy for any companies. World Wide Web appropriates eff...

While many antitumor drugs have yielded unsatisfactory therapeutic results, drugs are one of the most prevalent therapeutic measures for the treatment of cancer. The development of cancer largely results from mutations in nuclear DNA, as well as from those in mitochondrial DNA (mtDNA). Molecular hydrogen (H2), an inert molecule, can scavenge hydroxyl radicals (·OH), which are known to be the strongest oxidizing reactive oxygen species (ROS) in the body that causes these DNA mutations. It has been reported that H2 has no side effects, unlike conventional antitumor drugs, and that it is effective against many diseases caused by oxidative stress and chronic inflammation. Recently, there has been an increasing number of papers on the efficacy of H2 against cancer and its effects in mitigating the side effects of cancer treatment. In this review, we demonstrate the efficacy and safety of H2 as a novel antitumor agent and show that its mechanisms may not only involve the direct scavenging...
