“…The appearance of advection-driven heterogeneity in relation to single and multispecies ecological interactions was studied by Levin (1977), Levin and Segel (1976), Okubo (1980), Mimura and Murray (1978), Mimura and Kawasaki (1980), Mimura and Yamaguti (1982) and many other authors. These studies form a theoretical basis for modelling complex spatio-temporal dynamics observed in real systems (e.g., Badaev et al 1998).…”
