The purpose of this collection is to present some of the diversity of ideas
and studies about species that can be classifi ed as “ecosystem engineers.”
As with any developing concept, we fi nd disagreement about the
meaning and usefulness of this term in the literature and among ourselves.
The idea for the book arose in a National Center for Ecological
Analysis and Synthesis (NCEAS) working group designed to develop
models of ecosystem engineering species.
(BQ) Looking back at the creation and accelerated development of the early U.S. and former-Soviet "space race," ebook Scientific American: Great Moments in Space Exploration profiles the intrepid American astronauts and Russian cosmonauts who boldly ventured where none had gone before. It also offers current facts on the most recent developments in space technology, including those involving international cooperation among countries.
engineered solutions often work against nature, particularly when they aim to constrain regular
ecological cycles, such as annual river flooding and coastal erosion, and could further threaten
ecosystem services if creation of dams, sea walls, and flood canals leads to habitat loss.
In order to permanently preserve the quality of habitat
for bird species resident to the Weidmoos, it was essential
to alter the post-extraction state of the site, so that an
open landscape with numerous bodies of water and
moist areas would remain.
The most important measure to ensure the long-term
conservation of the Weidmoos as an open landscape –
and therefore as a valuable bird habitat – is the so-called
“re-waterlogging” of the site.
