In the framework of the &quot;MEDCORE&quot; project, particular emphasis has been put on the study of terrestrial isopod diversity in the Berkoukech area (north-west of Tunisia). Two sites were selected for this study: the beach dune system and an inland site located in Rabouet Bou Ali. In the beach dune system, isopods were studied in three biotopes: a grazed meadow (biotope 1), a maquis of Pistacia lentiscus, Quercus coccifera, Erica arborea, Phylleria angustifolia, and Callycotome villosa (biotope 2), and a climax forest of Quercus coccifera, Juniperus oxycedrus, Juniperus phoenicea, and Callycotome villosa (biotope 3). In Rabouet Bou Ali, a Quercus suber forest (biotope 4) was chosen for study. In the Berkoukech area, 12 species of terrestrial isopods belonging to five families were collected: Tylidae, Porcellionidae, Philosciidae, Platyarthridae, and Armadillidiidae. Among these, two species are reported as new for Tunisia. Furthermore, this study indicates that isopods are not evenly distributed in the various biotopes: they vary in number of species as well as in number of specimens. Biotope 2 shows the highest diversity and is the most homogeneous (Is = 3.16; H′ = 1.76; J′ = 0.88), while biotope 4 exhibits the lowest values (Is = 1.2; H′ = 0.475; J′ = 0.3). The similarity between the various communities, estimated by the Bray-Curtis index, shows that the biotopes cluster according to their plant associations.</style></abstract><issue><style face="normal" font="default" size="100%">8</style></issue></record></records></xml>
