In an especially marvelous episode in Don Quixote, the mad
knight errant attacks Master Peter’s puppet show. He takes his sword to the
puppets and the fittings and destroys the show. Confronted with the extent of
the damage Don Quixote is unmoved, claiming that an enchanter had transformed
the scene he had witnessed – in which Sir Gaiferos frees his wife Melisendra
from the Moors – into the puppet show which he was then, naturally, compelled to reduce to
wooden carnage. Don Quixote, the Knight of the Sad Countenance, might be a
fitting patron of the ecologically naïve, failing as he does to perceive the
realities of important connections, confusing what he sees with what fits the
vision of his madness. The explicit role of ecology is to excavate these
connections and to make transparent realities that might otherwise, to our
cost, elude us.
In recent years ecological exploration has attended to the
role of soil organisms and to the ecosystem processes occurring primarily
belowground. This skein of research has resulted in a mild revolution (ecological revolutions tend to be bloodless and polite, but revolutions none
the less) in our thinking. This reorientation in thinking is referred to as
plant-soil feedback theory, the central claims of which are that the structure
and functioning of ecosystems cannot be fully understood without appreciating
the influence of the aboveground component of ecosystems on the soil and
reciprocally of the influence of the soil on the communities above the soil
surface. In effect the strings that run the Master Peter's ecological puppet show run not only
from above, but emerge from the opaque but teeming world of the soil.
