Abstract: Isopods of a dry oak forest and the surrounding ruderal vegetation were sampled along a line transect by pitfall trapping. The captured species were Armadillidium vulgare Latr. (46.16%), Porcellium collicola Verh. (33.16 %), Trachelipus rathkei Brandt (10.29 %) and Trachelipus ratzeburgi Brandt (9.47 %). Difference was not found between the spatial distribution of A. vulgare and P. collicola. T. ratzeburgi seemed to prefer the inside of the oak forest, whereas individuals of T. rathkei were trapped mainly in the ruderal vegetation. The ratio of gravid females of T. rathkei was conspiciously higher at the sampled places than that in wetland forest. This phenomenom is probably due to the effect of the less suitable habitat. The seasonal changes of surface activity and sex ratio were also examined.
