Abstract

Spatio-temporal patterns of the coexistence of the two Millipede species have been studied in a temperate woodland ecosystem in Paris area. These closely related species show the same individual stature and weight. In holorganic and upper soil layers, C. nitidus abundance is twice C. punctatus one. In return, only C. punctatus lives in decaying logs, chiefly during mating and laying times. The two species are partly separated by seasonal migrations between litter layers, logs and deep soil layers but they occur simultaneously in the upper soil layers (at least in spring and autumn). Nevertheless, the two populations show a clear tendency in sharing space horizontally and forming distinct aggregates.
