  • The oceans cover over 70% of our planet's surface. Their physical, chemical and biological properties form the basis of the essential controls that facilitate life on Earth. Current concerns such as global climate change, pollution of the world's oceans, declining fish stocks, and the recovery of inorganic and organic chemicals and pharmaceuticals from the oceans call for greater knowledge of this complex medium. This volume brings together a number of experts in marine science and technology to provide a wide-ranging examination of some issues of major environmental impact....

  • First and foremost, it is a book geared towards fish aquarists. And it is a heavy read with alot of chemistry and biology. To sum up the book: the author wrote the book to bring it to the reader's attention that an aquarium is a sort of (semi)closed ecosystem, and it needs to be thought of as this in order to be successful in raising the plants and animals inside the aquarium. she then describes the biological principles behind her methods of setting up and maintaining "low-tech" planted aquariums (as opposed to hi-tech, like those of takashi amano). She uses...

  • Weather natural hazards, the environment and climate change are of concern to all of us. Especially, it is essential to understand how human activities might impact the nature. Hence, monitoring, research, and forecasting is of the outmost importance. Furthermore, climate change and pollution of the environment do not obey national borders; so, international collaboration on these issues is indeed extremely important.

  • When planning how to reduce the threat of global warming and how to adapt to it, a very important piece of information is how intense the change will be. That implies estimating the trends of future concentrations of greenhouse gasses, and the potential future changes in temperature, precipitation, storm events and other climatic variables. These predictions are important not only to estimate the magnitude of the changes, but also to determine the uncertainty surrounding them.

  • Soil communities are important aspects of biodiversity and they are involved in many important ecosystem processes, particularly nutrient cycling. Soil chemistry is neither an aspect of biodiversity nor one of the primary causes of change addressed by this project. Nevertheless, understanding mechanisms of change and correctly attributing effects to causes are central to the project, making it necessary to understand the soil chemistry at sites.

  • Drawing on the collective expertise of world authorities, Ecological Basis of Agroforestry employs extensive use of tables and figures to demonstrate how ecologically sustainable agroecosystems can meet the challenges of enhancing crop productivity, soil fertility, and environmental sustainability. Divided into four sections, this comprehensive volume begins with a study of tree-crop interaction in tropical and temperate climates.

  • The ocean absorbs a significant portion of carbon dioxide (CO2) emissions from human activities, equivalent to about one-third of the total emissions for the past 200 years from fossil fuel combustion, cement production and land use change (Sabine et al., 2004). Uptake of CO2 by the ocean benefits society by moderating the rate of climate change but also causes unprecedented changes to ocean chemistry, decreasing the pH of the water and leading to a suite of chemical changes collectively known as ocean acidification.

  • Phytochemistry is a broad area, generally termed ‘‘plant chemistry.’’ Investigations in the field of phytochemistry are important for numerous research disciplines, such as plant physiology, plant biochemistry, chemosystematics (which is often referred to as chemotaxonomy), plant biotechnology, and pharmacognosy. Plant physiology focuses on the life processes occurring in plants. Especially important are the investigations on the influence of various external factors, such as ultraviolet–visible (UV–Vis) radiation, temperature, the nature of soil, the climate, etc.
