The importance of forests and wetlands from the Tur River natural protected area in conservation of native terrestrial isopod fauna

In the Tur River natural protected area we identified 18 terrestrial isopod species: Ligidium hypnorum, L. germanicum, Trichoniscus carpathicus, Hyloniscus riparius, H. transsilvanicus, Haplophthalmus danicus, Cylisticus transsilvanicus, C. convexus, Protracheoniscus politus, Porcellium collicola, Trachelipus difficilis, T. arcuatus, T. rathkii, T. nodulosus, Porcellionides pruinosus, Porcellio scaber, Armadillidium vulgare, A. versicolor. The species L. hypnorum, L. germanicum, T. carpathicus, H. transsilvanicus, P. collicola and T. difficilis occur in wet areas, forested and natural areas; P. politus and T. rathkii in semi-natural forests with relatively moist soil, and T. arcuatus, T. nodulosus and A. vulgare seem to tolerate a wide variety of the characteristics of the habitats. The highest species diversity was found in natural habitats: wetlands and natural forests. The great species richness in semi-natural habitats is due to the presence of both the species typical to natural areas and the synanthropic ones. The high diversity and species richness near distilleries is due to the preference of terrestrial isopods for moisture and the large amounts of organic matter available. Identification of C. transsilvanicus has zoogeographical significance.
