Scheuring & Janosi described a metapopulation model which did not exhi
bit chaotic dynamics. Indeed, contrasting results were observed in sim
ilar studies. The general issue behind these works is the occurrence o
f complex and unpredictable dynamics in biological populations. I woul
d like to comment specifically on Scheuring & Janosi's paper, and more
generally on the issue of chaos in population dynamics. (C) 1997 Acad
