Abstract

Air currents were recorded at 44 separate underground Locations in 12 badger Metes metes setts (five ‘main setts’ and seven ‘outliers’). Within-sett air movements were strongly positively correlated with, but were from one to three orders of magnitude slower than, corresponding external wind speeds. Within-sett air movements were significantly weaker in sheltered setts than in open setts, and significantly stronger in nest chambers than in tunnels. Main setts were better ventilated than outliers at sampling locations that were relatively deep within a sett (i.e., more than 1 m from the nearest entrance). We conclude that wind-induced movement of air within badger setts contributes to ventilation of the interior of the sett, and that large setts are better ventilated than small ones.

Ventilation in Bauen des Dachses Metes meles

Zusammenfassung

Luftbewegungen wurden an 44 separaten Untergrundpositionen in 12 Bauen (fünf ‘Hauptbauen’ und sieben ‘Auslegerbauen’) des Dachses (Metes metes) gemessen. Luftbewegungen im Bau waren positiv korreliert zur korrespondierenden Windstärke außerhalb des Baues, aber zwischen ein und drei Größenordnungen langsamer. Luftbewegungen im Bau waren schwächer für windgeschützte als für windungeschützte Baue, und stärker in Schlafkammern als in Tunneln. Luftbewegungen im Bau hingen nicht von der Anzahl der Baueingänge ab, aber Hauptbaue waren tief im Innern besser ventiliert als Auslegerbaue. Es wird gefolgert, daß windbedingte Luftbewegungen in Dachsbauen zur Ventilation des Bauinneren beitragen.
