The niche concept in Applied Ecology: There's many a slip twixt the reality and the niche
Our objective is to analyse the use of the niche concept into what we generally call Applied Ecology. In the first place, we emphasize the problems in defining and understanding what is the niche. We go quickly through the ideas and properties that had been associated with it since its origins. The...

It also results hardly suitable to contribute to any "ecological technology".

Our objective is to analyse the use of the niche concept into what we generally call Applied Ecology. In the first place, we emphasize the problems in defining and understanding what is the niche.

We cannot assume that a "measured" niche has a consistent and applicable meaning.
