Named for John Muir, a California naturalist who emphasized the interconnection of all things in nature, and who worked to preserve wilderness in America. A Muir web shows how different species are connected to each other not only in that one may eat the other, but also, for instance, in that one species may provide shelter for another. A Muir web includes not only living species but also abiotic elements, like water, sun, soil and air. Such a web also includes habitats as discrete nodes.
