Описание: This book is the final installation in a three-volume series synthesizing 30 years of mercury research in the Florida Everglades. The first part of this book evaluates the occurrence of trends in both biota mercury concentrations and atmospheric mercury deposition.
This book integrates 30 years of mercury research in the Florida Everglades to inform scientists and policy makers. The Everglades is an iconic ecosystem by virtue of its expanse; diversity of biota; and multiple international designations. Despite this, the Everglades has been subjected to multiple threats including: habitat loss, hydrologic alterations, invasive species and altered water quality. Less well recognized as a threat to Everglades human use and wildlife populations is the toxic metal, mercury.
The first half of Volume II focuses on biogeochemistry and factors unique to the Everglades that make it extraordinarily susceptible to mercury methylation following its deposition: warm subtropical climate, shallow depth, high levels of dissolved organic matter, sulfate contamination, nutrient enrichment and sediment redox conditions (for review of atmospheric mercury deposition significance, see Vol. I). The second half of Volume II answers the “so what” question – why biomagnification of the methylmercury produced in the Everglades is a threat to the health of top predators including humans. The results of the synthesis presented in Volume II suggest that the mercury problem in the Florida Everglades is one of the worst in the world due to its areal extent and the degree of risk to ecological receptors and humans.
Описание: This book integrates 30 years of mercury research on the Florida Everglades to inform scientists and policy makers. The Everglades is an iconic ecosystem by virtue of its expanse; diversity of biota; and multiple international designations. Despite this, the Everglades has been subjected to multiple threats including: habitat loss, hydrologic alterations, invasive species; and altered water quality. Less well recognized as a threat to Everglades human use and wildlife populations is the toxic metal, mercury. This Volume focuses on sources of mercury to the Everglades from the late-1980’s when there was bewilderment as to why there were very high levels of mercury in the Everglades food web. Soon came the finding that mercury loadings from atmospheric deposition accounted for over 95% of total input to the Everglades which resulted in Florida conducting the most comprehensive mercury monitoring and modeling study performed to date. Topics discussed in this Volume include: (1) Why atmospheric deposition fluxes of mercury to the Everglades are amongst the highest in the U.S; (2) That these are overwhelmingly from sources outside of the U.S; (3) That mitigation strategies for resolving the elevated food web mercury problem in the Everglades that rely solely on reducing atmospheric mercury inputs will not be effective for many decades; (4) That consideration of other strategies, in particular controlling factors related to Everglades mercury biogeochemical cycling seem warranted.

Описание:
Only a century ago, nearly all of South Florida was under water. The Everglades, one of the largest wetlands in the world, was a watery arc extending over 3 million acres. Today, that wetland ecosystem is half of its former self, supplanted by housing for the region's exploding population and over 700,000 acres of crops, including the nation's largest supply of sugar cane. Countless canals, dams, and pump stations keep the trickle flowing, but rarely address the cascade of environmental consequences, including dangerous threats to a crucial drinking water source for a full third of Florida's residents.
In Moving Water, environmental journalist Amy Green explores the story of unlikely conservation heroes George and Mary Barley, wealthy real estate developers and champions of the Everglades, whose complicated legacy spans from fisheries in Florida Bay to the political worlds of Tallahassee and Washington. At the center of their surprising saga is the establishment and evolution of the Comprehensive Everglades Restoration Plan (CERP), a $17 billion taxpayer-funded initiative aimed at reclaiming this vital ecosystem. Green explains that, like the meandering River of Grass, the progress of CERP rarely runs straight, especially when it comes up against the fierce efforts of sugar-growing interests, or "Big Sugar," to obstruct the cleanup of fertilizer runoff wreaking havoc with restoration.
This engrossing expos tackles some of the most important issues of our time: Is it possible to save a complex ecosystem such as the Everglades--or, once degraded, are such ecological wonders gone forever? What kind of commitments--economic, scientific, and social--will it take to rescue our vulnerable natural resources? What influences do special interests wield in our everyday lives, and what does it take to push real reform through our democracy? A must-read for anyone fascinated by stories of political intrigue and the work of environmental crusaders like Erin Brockovich, as well as anyone who cares about the future of Florida, this book reveals why the Everglades serve as a model--and a warning--for environmental restoration efforts worldwide.

Описание: This volume explores major wetland ecosystem services, such as climate cooling and water quality improvement, and discusses the recent wetland conservation and restoration activities in China and neighboring countries. The role of wetlands in either cooling or warming the climate is analyzed as the net balance between carbon sequestration and emissions of methane and nitrous oxide. Wetlands start off having a net warming effect on the climate but in time switch to net cooling. Further, they remove 40% of the N and P from run-off and groundwater flow in agricultural areas, but wetlands need to amount to 10% of the total catchment area to make a difference.Reflecting on the recent large investment in wetland ecological studies in China and neighboring countries, the book addresses invasive species in coastal wetlands as well as the protection and wise use of tidal flats around the Yellow Sea. It also presents promising regional case studies on wetland restoration. The book is intended for academics, students and practitioners in the field of wetland ecology, management and restoration, as well as consultants and professionals working in conservation, wise use and environmental policy.

?The risks and consequences of environmental change are increasing, leading to massive losses in terms of ecosystems and having a huge impact on human populations. As such, global thinkers, environmentalists, scientists and policy makers are focusing on finding solutions and ways to sustain life on Earth. Anthropogenic impacts on the climate system can only be mitigated by the restoration of existing natural resources and the sustainable development of the environment and society.
This book discusses the potential of green technology in waste management, wetland restoration, presenting the latest developments in the field of bioenergy, green ecology, bioremediation and microbial management. Wetlands are one of Earth’s most important ecosystems, and they provide valuable services to human societies, such as minimizing the impacts of floods, acting as a carbon sink, and offering water purification as well as recreational opportunities. Wetlands may be natural or constructed, and the effectiveness of wetland services largely depends on the diversity of macrophytes affecting the algal production, plant biomass and nutrient status of the system. In addition, they are one of the richest microbial ecosystems on earth: the rhizosphere, soil and water interface enhances wetland services with implications ranging from phytoremediation to microbial bioprospection. However, in order to function properly, they need to be effectively redesigned, reengineered, protected and maintained.
The book addresses the dynamic relation between three global concerns: environmental pollution, resource exploitation and sustainability. It describes the utilization of resources like wastes (municipal, industrial, agricultural, mine drainage, tannery, solid, and e waste), plants, algae and microbes for production of renewable biofuel, biofertilizers and other value added products to achieve the goal of sustainable development. The book also discusses the current and future trends in employing wetlands in improving water quality. In addition it presents the latest international research in the fields of wetland science, waste management, carbon sequestration and bioremediation.
Highlighting a broad spectrum of topics and strategies for achieving a sustainable environment, the book offers researchers, students and academics insights into utilizing resources in a sustainable way.
