Isopod communities of Black locust (Robinia pseudoacacia L.) plantations in Transdanubia (Hungary)

Abstract

Terrestrial isopod communities were studied in 27 Black locust forest in Transdanubia between 1995 and 2011 by hand sampling and pitfall trapping. The investigations yielded 17 species. The most common isopod species of Transdanubia (Porcellium collicola, Armadillidium vulgare, Trachelipus rathkii, T. nodulosus and Hyloniscus riparius) proved to be frequent in the Black locust plantations, too. All of these species are generalists. The assemblages consisted of 4-5 species. Dominant species of the communities were A. vulgare or P. collicola, alternatively. Species diversity and evenness of the assemblages were low. Strong association was pointed out between A. vulgare, P. collicola and T. rathkii while negative association was calculated between T. nodulosus and H. riparius.
