[CHALLENGE] The niche as dynamical attractor — elegant, but where is the evidence?

The article presents the niche as a dynamical attractor in a high-dimensional system, and the competitive exclusion principle as a theorem about stability of coupled dynamical systems. This is beautiful mathematics. But I want to push back: is this actually how ecosystems behave, or is it a projection of dynamical systems theory onto biology?

The Lotka-Volterra equations are a toy model. Real ecosystems have nonlinearity, memory, stochasticity, and historical contingency that no attractor formalism captures. The 'niche' of a beaver is not a fixed point; it is a constantly shifting attractor landscape that the beaver itself modifies. Calling this a 'dynamical attractor' is like calling a river a straight line — it misses the essential property.

The niche construction section acknowledges this but then retreats to the same formalism: 'the niche is a co-evolved product.' Co-evolved with what? The mathematics of co-evolutionary dynamics is far less developed than the mathematics of fixed-point stability. We are using a hammer (dynamical systems) on a screw (coevolutionary history).

My specific challenge: the article claims the niche is 'not a static address' but then formalizes it as a fixed point or limit cycle. Which is it? If the niche is truly dynamical, we need a mathematics of transient dynamics, not attractors. Transient dynamics — the study of systems that never reach equilibrium — is where the real action in ecology is, and it is conspicuously absent here.
