The Stable Heteroclinic Sequence (SHS) in Lotka-Volterra systems is known to be robust in the presence of temporal fluctuations. In this paper, we study the robustness of SHS in Lotka-Volterra systems in the presence of randomness in the connectivity. The occurrence of a rich class of dynamics is observed by varying the disorder strength. We show that the quenched disorder introduces rich dynamical states: stable heteroclinic sequence fixed point localized sequence unstable dynamics, in these systems.
