| Summary: | Includes bibliographic references The opilionid Leiobunum elegans was found overwintering in caves and mines in mainland Nova Scotia and Cape Breton Island. It occurred both as adults and near-adults. usually as single individuals or small clusters, but aggregations were formed at one site. It is suggested that aggregation formation is a behavioural adaptation for coping with saturated atmospheres. This is the first published report of overwintering opilionids in such habitats from eastern Canada. L'opilionide Leiobunum elegans a été trouvé en hivernement dans des caves et des mines de l'lle du Cap Breton et aussi de la Nouvelle-Écosse continentale. Ceci a eu lieu comme adultes ou quasiadulles, ordinairement comme individus ou en petits groupes, mais des agréations ont été trouvées à un seul lieu. On suggère que la formation d'agrégations est une adaptation de componement afin d'endurerdes atmosphères saturées. La publication de l'hivernement d'opilionides dans de tels habitats est la premiè ayant trait à l'est du Canada. |
