Comment: Meet the Glomales - the ecology of mycorrhiza
The role of lower organisms in both natural and man-made ecosystems is grossly underestimated. They go unnoticed because they are too small to see or they live in the dark, impenetrable world of the soil. Worse still, inestimable numbers of microbes are unculturable, so that it is impossible to discover their biology in the laboratiry. Some, maybe very many, have yet to be detected. There are so many organisms about which we know little or nothing, and we deny their ecological importance and disrupt their environment at our peril.
