- Abstract
Abstract: Amphipoda and Isopoda were sampled in 40 Tunisian wetlands, and their fauna were compared at four different types: lagoon, sebkhas, dams and hill reservoir. At each station, eight quadrates of 50 × 50 cm were randomly placed. Amphipoda and Isopoda were collected by hand. They were identified to species level. At each station, analyses of organic matter, sodium, calcium and heavy metals content from the soil collected in each station were performed. We recorded 19 and eight species for respectively Isopoda and Amphipoda and caught 3,035 specimens in total. The highest isopod's species richness (11 species) was noted around hill reservoirs and dams, a quite similar richness in the banks of lagoons (10 species) but only six species in the sebkhas. Eight amphipod species were recorded in the supralittoral zone of lagoons, three species around sebkhas but no amphipods were found in samples from dams and hill reservoirs. Isopod species richness was positively correlated with soil humidity. However, the distribution of the species Orchestia mediterranea, Orchestia gammarellus, Orchestia montagui, Orchestia stephenseni and Platorchestia platensis was related to soil metal concentrations.
