Revision systematique des Leptodirinae souterraines des Monts Apuseni. VII. Les sous-genres Pholeuon (sstr.) du bassin de Crisul Negru (Monts du Bihor)

Dans cette septième et dernière étude régionale faisant partie de la révision systématique que nous avons initiée treize ans auparavant, on a disposé de neuf échantillons faunistique totalisant 1.297 individus (579 mâles et 718 femelles). Les résultats fournis par le traitement statistique des données biométriques montrent, dans ce cas de manière encore plus nette que d’habitude, qu’une différenciation des taxons infra-spécifiques n’est pratiquement possible qu’en tenant compte non seulement de la similitude morphologique, mais aussi du facteur biogéographique. Sans que ce dernier soit pourtant utilisé en tant qu’élément de diagnose proprement-dit, cinq sous-espèces nouvelles de Pholeuon (s. str.) leptodirum on pu être identifiées: P. l. problematicus, P. l. jeanneli, P. l. moldovani, P. l. fagensis et P. l. nanus. Par ailleurs, certaines modifications ont dues être opérées dans la classification proposée par Jeannel (1923) et acceptée jusque de nos jours

The impact of tourism in Romanian show caves: the example of the beetle populations in the Ursilor Cave of Chiscau

The disoovery of the Ursilor (Bear\u27s) Cave (Apuseni Mountains, Romania) in the 70th was followed by climatic and biological studies, before its opening as a show cave. Twenty years later these researches were undertaken again The tourism has impacted on the populations of two endemic cave beetles: Pholeuon leptoderum and Drirneotus n. sp. The first one became extremely rare in the tourist part of the cave. Drimeotus has adapted different dynamics during the year in the two parts of the cave; near the tourist path the populations evolves depending on the affluence of the tourists in the summer months, and in the protected part has kept the same pattern as in the early studies
