  • As a wetland of international importance located in China, the Poyang Lake Basin's incredible topographical and biological diversity has provided a congregating point for scientists from around the world to engage in cross-disciplinary research. In particular, the International Conference on Poyang Lake Complex Environment System was instrumental in bringing together scholars from China, North America, and Europe to explore the latest innovations in water resource science and watershed management.

  • Marine birds are equally at home on land, in the air, and in the water. While many organisms can go from land to water (amphibians, some reptiles, some insects), others generally live in only one medium during their lives. Marine birds switch from one to the other, often daily. Such flexibility requires unique physiological and morphological adaptations to the environment, a medium that has also exerted selective forces on the behavior, ecology, and demography of these birds.

  • Praise, they say, is stricken dumb by the greatest names, and also, we may add, by the greatest deeds. It is only by the bare simplicity of faithful narrative that we can hope not to belittle these. But yesterday the public had no knowledge of the great, heroic things accomplished by the Brigade of Marines (Fusiliers Marins). They were hidden under a confused mass of notes, communiqués, instructions and plans of operations, private letters, and newspaper articles. It has been no easy task to bring them to light--the discreet light permitted by the censorship.

  • There is a new era of global environmental factors that needs to be addressed via sound Corporate Environmental Management. Environmental problems are a key area of concern for the global community in the new 21st century. A sustainable global community is emerging that is geared toward preserving limited resources and the natural ecology, but to do so requires resource conservation and the reduction of environmental pollution loads across all human activities.

  • The environment is key to sustaining human economic activity and well-being, for without a healthy environment, human quality of life is reduced. Most people would agree that there are also many reasons to protect the environment for its own inherent worth, and especially to leave a legacy of fully functioning natural resources. Sustainable land management refers to the activities of humans and implies that activity will continue in perpetuity. It is a term that attempts to balance the often conflicting ideals of economic growth and maintaining environmental quality and viability....

  • Research over the past decade has demonstrated the feasibility of extracting topographic information of hydrological interest directly from digital elevation models (DEM). Techniques are available for extracting slope properties, catchment areas, drainage divides, channel networks and other data (Jenson and Domingue, 1988; Mark, 1988; Moore et al., 1991; Martz and Garbrecht, 1992). These techniques are faster and provide more precise and reproducible measurements than traditional manual techniques applied to topographic maps (Tribe, 1991)....

  • The Pacific Islands region contains about 200 high islands and about 2 500 low islands and atolls. Apart from the Pitcairn group and the southern part of French Polynesia in the east of the area, all the islands of the area lie in the tropical zone. In general, the islands increase in size from east to west, with Papua New Guinea at the western-most edge of the region having most of the region’s land area. The islands mostly rise steeply from the deep ocean floor and have very little underwater shelf.

  • WWF-Norway has, during the writing of this report, received great interest both from industry, governments and other NGOs. WWF hopes that addressing this issue will contribute in the long quest for protecting the biodiversity in our oceans. The report looks into the raw materials used for feed in aquaculture, specifically of salmon and trout. It examines the sustainability of the fisheries which are exploited to produce the feed, the added pressure the fish farming industry puts on those stocks, the efficiency of feeding fish to carnivorous fish, and some of the alternatives....

  • The study conducted by Hiller et al. (2011) to investigate the concentrations, distributions, and hazards of polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs). PCBs are used mainly as coolant and electronic industries (capacitors, transformers), paints, sealants for wood, cutting and lubricating fluids, plasticizers, and as dielectric fluids. Therefore, at the former site of PCB manufacturing area in Slovakia, high concentrations of PCBs are detected in soils, sediments, humans, and wildlife (Kocan et al., 2001; Petrik et al., 2001; Hiller et al., 2011)....

  • The last decade has contributed significantly to the development of research on the biogeochemistry of tropical mangrove ecosystems. Also obvious during the last decade is the continued and dramatic destruction of natural tropical mangrove resources in Southeast Asia (Fig. 1.1). The naturally high productivity of tropi- cal mangroves has traditionally been exploited for a wide variety of purposes, both as sources of forestry or fisheries products and they have also been used for human settlement (Hatcher et al., 1989; Platong, 1998).

  • This volume, the first in a series, presents the findings of an ambitious project—to measure the impact of fishing on the ecosystems that make up the North Atlantic Ocean and to propose ways to mitigate that impact. The project arose from a request by Dr. Joshua Reichert, the Director of the Environment Program of the Pew Charitable Trusts, Philadelphia, to answer six specific questions about the North Atlantic: • What are the total fisheries catches from the ecosystems, including reported and unreported landings and discards at sea?...

  • Ennore Creek becomes the pollution point in Bay of Bengal which influences the marine resources and productivity of the region. This coastal belt in the neighboring areas of the city is viewed as dumping sites for industrial effluents and disposing domestic waste (Arunagiri et al., 1998). The natural wealth of the creek is now being eroded to mere sewage channel (Jayaprakash, 2003). The Ennore Thermal Power Plant uses the river waters as coolant and lets out the warm water, in the Ennore Creek.
