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.
?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.

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.
