Abstract
A comparative analysis of soi! Collembola using two types of sclerophyllous vegetation (Quercus ilex and Quercus coccifera) was perfonned at a calcareous site in Provence (France). Collembola populations were examined over a one-year period (11 successive months) in three different soi! layers. Although no statistically significant differences could be observed for Collembola abundance and diversity, multivariate analyses (FCA) differentiated the two coppices. Phenologies of some species showed specific responses to the microclimate induced by edaphic conditions. Even though the two coppices were sclerophyllous, the structure of each vegetation, the quantity and quality of litter, which were dif ferent, could influence environmental conditions and thus the dynamics of collembolan populations.
