The emergence of landscape ecology during the 1980s represents an
impor tant maturation of ecological theory. Once enamored with the
conceptual beauty of well-balanced, homogeneous ecosystems,
ecologists now assert that much of the essence of ecological
systems lies in their lumpiness. Patches with differing properties
and behaviors lie strewn across the land scape, products of the
complex interactions of climate, disturbance, and biotic processes.
It is the collective behavior of this patchwork of eco systems that
drives pattern and process of the landscape. is not an end point
This realization of the importance of patch dynamics in itself,
however. Rather, it is a passage to a new conceptual framework, the
internal workings of which remain obscure. The next tier of
questions includes: What are the fundamental pieces that compose a
landscape? How are these pieces bounded? To what extent do these
boundaries influence communication and interaction among patches of
the landscape? Will con sideration of the interactions among
landscape elements help us to under stand the workings of
landscapes? At the core of these questions lies the notion of the
ecotone, a term with a lineage that even predates ecosystem. Late
in the nineteenth century, F. E. Clements realized that the
transition zones between plant communi ties had properties distinct
from either of the adjacent communities. Not until the emergence of
patch dynamics theory, however, has central signif icance of the
ecotone concept become apparent."
Peter is a young man with no future other than working his little
farm. Then one day his cousin brings him the news that his
grandfather is dying. Suddenly everything changes. His grandfather
holds the secret that will break the Dark Prince's iron grasp of
their valley. That secret is held in ten golden puzzle pieces
which, once found and put together, will enable the King to return.
With his grandfather dead, Peter is the only one who has a chance
of completing the puzzle in time. He begins at once on the quest,
but soon realizes that the Dark Prince will do anything in his
power to stop him.
