# 7.6: Bifurcation diagram

The dynamics of all possible values of *r* can summarized in a “bifurcation diagram” (Figure \(\PageIndex{1}\)). In mathematical terminology, a bifurcation is a place where a tiny change in a parameter causes an extensive and discontinuous change in the behavior of the system. Figure \(\PageIndex{1}\) shows this by amalgamating the distributions on the right in Figures 7.3.1 through 7.4.2, plus distributions for all other possible values of *r*. Shading shows where the population spends most of its time. Starting at the right of this figure, fully in the domain of chaos, and moving to the left by reducing *r*, the behavior moves in and out of chaos-like patterns that never repeat and thus have no period, and also hits stable patterns of every possible period from one up toward infinity.
