Yasemin Baytok makes a good point. Obviously, we must avoid extending
the breadth of what is taught so far that any connection to the
original discipline (Ecology) disappears.
There are, however, eclogical aspects of of environmental engineering
and forest engineering that can be taught or

I assume that probably for every successful introduction, you could find
someone who liked something about it and someone who didn't like
anything about it. I'm generally against introductions in part because
of the uncertainty--we have shown over and over that we are poor
predictors of the
Hello,
I've been out of this list for many years and signed it again two days ago.
I'm very glad to see that it shifted from mainly naive questions about
environmentalism to serious discussions about the science of ecology like
that exciting messages about the niche theory.
Back to the
Whether or not introduced species are bad in every case is something that
we really can't predict. We can, however, say for sure that introducing a
non-native species into a new ecosystem does introduce much uncertainty.
More often than not, this often results in competition with native
species.
Most silviculture in practice is little more than tree-farming. There is
a lot of confusion in the ranks due to the varied forest management
strategies running from a bonifide tree farm to the ecosystem we know as a
forest. A treefarm is no different than a cornfield, having grown up in

I agree with Hilmy that a niche is more than just a physical space, I
think of a niche in functional terms more than geographical. The
niche is its fuctional space in a particular ecosystem. Any given
species may occupy different niches within different ecosystems, and there
is typically much
Well, I usually don't think in the niche as some sort of entity like some
people do.
In my vision, the niche is a set of opportunities that an organism is able
to explore. It can be constrained in part by the conditions offered by the
environment and part by the phylogenetic restrictions of
We ecologists define the niche. We can stick with the Hutchinsonian
definition, or we can modify it in ways we might find more useful.
Niches, empty or not, are not fixed. If there is a lot of breadth, then
organisms will tend to partition the hyperspace among themselves.
Consider David Lack's
