Cyanobacteria have existed for 3.5 billion years, yet they are still the most important photosynthetic organisms on the planet for cycling carbon and nitrogen. The ecosystems where they have key roles range from the warmer oceans to many Antarctic sites. They also include dense nuisance growths in nutrient-rich lakes and nitrogen-fixers which aid the fertility of rice-fields and many soils, especially the biological soil crusts of arid regions. Molecular biology has in recent years provided major advances in our understanding of cyanobacterial ecology. Perhaps for more than any other group of organisms, it is possible to see how the ecology, physiology, biochemistry, ultrastructure and molec...

Phytoplankton ecology has developed from an understanding of taxonomy, species dynamics and functional roles, and species interactions with the surrounding environment. New and emerging technologies enable a paradigm shift in the ways we monitor and understand phytoplankton in a range of environments. Advances in Phytoplankton Ecology: Applications of Emerging Technologies is a practical guide to these new technologies and explores their application with case studies to show how recent advances have changed our understanding of phytoplankton ecology.Part one of this book explores how traditional taxonomy and species identification has changed, moving from morphological to molecular technique...

Now a major film, starring George Clooney, Ewan McGregor, and Jeff Bridges, this New York Times bestseller is a disturbing and often hilarious look at the U.S. military's long flirtation with the paranormal—and the psy-op soldiers that are still fighting the battle. Bizarre military history: In 1979, a crack commando unit was established by the most gifted minds within the U.S. Army. Defying all known laws of physics and accepted military practice, they believed that a soldier could adopt the cloak of invisibility, pass cleanly through walls, and—perhaps most chillingly—kill goats just by staring at them. They were the First Earth Battalion, entrusted with defending America from all kn...
