Matt Jones explains the grid computing concept and describes a major new grid computing initiative for ecologists; Bill Michener fleshes out the context of that initiative with a sketch of SEEK, a wide-reaching grant for information technology in ecology. Peter Arzberger and others give us an insider’s look at an international grid computing effort for environmental science. Chad Berkley and Peter McCartney bring us up to date on the latest tools for doing ecology “on the grid”. Then, Matt Jones is back to unveil the long-awaited release of EML 2.0, and David Blankman gives us a candid introduction to the world of data modeling.
