Nematodes and their relationship to forest dynamics: I. Species and trophic groups

Abstract:

Nematode populations were studied in parallel with successional stages of forest dynamics (clearing, growth, mature and senescence phases) in a nature reserve within the state forest of Fontainebleau (La Tillaie, France). Soil conditions were identical in all habitats (acid mull). A heterogeneous nematode fauna was found, resulting from the natural forest dynamics: vertical distribution of animals, horizontal distribution according to the nature and density of the plant cover, and different trophic groups. We also demonstrated the characteristics of the disruption zone of the ecosystem (clearing) and the subsequent succession, depending on where the clearing occurred. Similarly, changes in trophic group emphasized the continuity in time from clearing to the senescence phase.
