An exciting foray into Earth's inland waters, the remarkable species they contain, and the conservation challenges of protecting them.When we call Earth "the blue planet" we immediately envision the vast oceans that cover most of its surface. But seas aren't the only bodies of water that make Earth special. Millions of diverse inland waters rush, meander, and seep throughout the planet, teeming with life. These streams, lakes, wetlands, and groundwaters are home to...

With a simple approach to essential information, Rubin’s Pathology: Mechanisms of Human Disease establishes the foundation for medical training and practice and delivers the perfect balance of basic pathology and bedside perspective to confidently and efficiently equip students for clinical success. More accessible than ever, this eighth edition emphasizes the coverage students need most—disease mechanisms, integration of mechanisms into organ system pathology, and application of pathobiol...

This succinct book gives an intimate view of the day-to-day functioning of a remarkable river that has figured prominently in history and culture—the Hudson, a main artery connecting New York, America, and the world. Writing for a wide audience, David Strayer distills the large body of scientific information about the river into a non-technical overview of its ecology. Strayer describes the geography and geology of the Hudson and its basin, the properties of water and its movements in the ...

l RNA tumor viruses have become increasingly utilized in studies of cellular transformation and gene regulation. The genes of retroviruses exist in two forms; as extrachromosomal, RNA-containing, infectious particles and as DNA pro 2 viruses stably associated with cell genes. Components from the extracellular form can be collected in large quantity and purified for the preparation of molec ular probes. These probes can be used to dissect the sequence of events required for the establishmen...
