Ecological extinction is defined as “the reduction of a species to such low abundance that, although it is still present in the community, it no longer interacts significantly with other species.”
Ecological extinction stands out because it is the interaction ecology of a species that is important for conservation work. They state that “unless the species interacts significantly with other species in the community (e.g. it is an important predator, competitor, symbiont, mutualist, or prey) its loss may result in little to no adjustment to the abundance and population structure of other species.”
This view stems from the neutral model of communities that assumes there is little to no interaction within species unless otherwise proven.
Estes, Duggins, and Rathburn (1989) recognize two other distinct types of extinction.
Global extinction is defined as “the ubiquitous disappearance of a species."
Local extinction is characterized by “the disappearance of a species from part of its natural range.”

Famous quotes containing the words extinction and/or ecological:
“Man is an over-complicated organism. If he is doomed to extinction he will die out for want of simplicity.”
—Ezra Pound (18851972)
“Could it not be that just at the moment masculinity has brought us to the brink of nuclear destruction or ecological suicide, women are beginning to rise in response to the Mothers call to save her planet and create instead the next stage of evolution? Can our revolution mean anything else than the reversion of social and economic control to Her representatives among Womankind, and the resumption of Her worship on the face of the Earth? Do we dare demand less?”
—Jane Alpert (b. 1947)
