For 10 points, name this reduction in fitness in organisms and species due to a conflict over resources.
The parameter theta quantifies how much this phenomenon is size-asymmetric. Joseph Connell said that the "ghosts of [this phenomenon] past" are explained by coevolutionary divergence. This phenomenon makes having a lower value for the R-star parameter more favorable. In a model for this phenomenon, all of the terms in the interaction matrix alpha have positive values. The Beverton–Holt model can be generalized to the "scramble" form of this phenomenon. Georgy Gause ("GYOR-ghee GOW-zee") concluded that no two species occupying the same niche can coexist due to this phenomenon, a principle called its namesake "exclusion." To generate Lotka–Volterra phase-plane diagrams, a coefficient named for this phenomenon for one species is divided by the carrying capacity for a different species. For 10 points, name this reduction in fitness in organisms and species due to a conflict over resources.
