Water is a valuable resource for humans (direct consumption, power, irrigation, industry) and provides essential habitat for many organisms, including highly valued fish species such as salmonids. Aquatic habitat is influenced by processes active not only in the near-stream (riparian) zone (e.g., provision of shade) but also over the entire watershed (e.g., hillslope hydrologic processes that c...

With the advent of increasingly sophisticated techniques for access, tropical forest canopy research has burgeoned in the last few years. Although an enormous amount of basic descriptive work remains to be done, canopy research is now entering a more advanced and ecological phase.
