Number Of Species

In July 2020 we analyzed the terrestrial isopod assemblages from different (mostly abandoned) railway constructions in Dobruja, eastern Romania. We identified 10 terrestrial isopod species, of which the most abundant and frequent were Porcellionides pruinosus (Brandt, 1833) and Armadillidium vulgare Latreille, 1804. We identified species that, in Romania, are present only in Dobruja: Leptotrichus pilosus Dollfus, 1905 and Trachelipus squamuliger (Verhoeff, 1907). Most of the species are common, generalist or synanthropic, connected to dry and open habitats. In abandoned railway-stations the number of species/samples was low (at most two), but at the base of a stone railway bridge in Babadag forest six species were found.

AbstractCaenorhabditis remanei was found in association with the terrestrial isopod Trachelipus rathkii at several wooded locations in southwestern Ohio. These associations were as developmentally arrested dauer larvae. The sites of association were the inner surfaces of the dorsal plates and ventral appendages. C. remanei associations also were observed with Armadillidium nasatum, Cylisticus convexus, and Porcellio scaber. They were not observed with Porcellio spinicornis even though P. spinicornis populations were intermingled with infested populations of T. rathkii. Consistent with the observed natural associations, C. remanei dauers were experimentally able to infest T. rathkii and P. scaber . Dauer larvae responded to confinement with isopods by nictating and by climbing upon these potential hosts. Experimental infestations were able to persist for at least five days. Long-term infestations were not attempted. Naturliche und experimentelle Vergesellschaftungen von Caenorhabditis remanei mit Trachelipus rathkii unde anderen terrestrischen Isopoden - An mehreren waldigen Stellen im Sudwesten von Ohio wurde Caenorhabditis remani vergesellschaftet mit dem terrestrischen Isopoden Trachelipus rathkii gefunden. Diese Assoziationen waren wie in der Entwicklung gehemmte Dauerlarven. Sie wurden an den inneren Oberflachen der Dorsalplatten und der ventralen Anhange festgestellt. Vergesellschaftungen von C. remani wurden auch mit Armadillium nasutum, Cylisticus convexus und Porcellio scaber beobachtet. Nicht beobachtet wurden sie dagegen bei Porcellio spinicornis, obwohl Populationen dieser Art mit infizierten Populationen von T. rathkii vermischt vorkamen. In Ubereinstimmung mit den beobachteten naturlichen Assoziationen konnten Dauerjuvenile von C. remani auch im Versuch T. rathkii und P. scaber befallen. Die Dauerjuvenile reagierten auf das enge Zusammensein mit den Isopoden durch Nickbewegungen und Klettern auf diese potentiellen Wirte. So ein experimenteller Befall konnte fur mindestens funf Tage bestehen. Langfristiger Befall wurde nicht versucht.

Terrestrial Isopod

The terrestrial isopod species of the subgenus Hemilepistus (Desertellio) are revised. Hemilepistus ruderalis (Pallas, 1771), H. heptneri Borutzky, 1954, H. pavlovskii Borutzky, 1954 and H. fedtschenkoi (Uljanin, 1875) are redescribed and their diagnostic characters are figured. Three species namely H. nodosus Budde-Lund, 1885, H. zachvatkini Verhoeff, 1930 and H. buddelundi Borutzky, 1945 are synonymized with H. fedtschenkoi, and H. russonovae Borutzky, 1945 is considered as a synonym of H. ruderalis. An identification key to Desertellio species is provided.
