Summer distribution of the Pond bat Myotis dasycneme (Chiroptera, Vespertilionidae) in the west of Flanders (Belgium) with regard to water quality
The summer distribution of the Pond bat Myotis dasycneme in the west of
Flanders was assessed by bat detector surveys and a radiotracking project
focusing on hunting activity as well as commuting activity. A preliminary
attempt was made to relate hunting activity to water quality data and some
field observations of nocturnal insect activity. This study revealed new records
of pond bats in the area including a small maternity roost. Recorded activity
was high over broad waterways, lower over large ponds and medium sized
waterways and very low over small waterways. Pond bats were observed
hunting over waterways with different pollution levels from mild to heavier
pollution. However more activity was recorded over waterways with mild
and moderate pollution than over polluted waterways, whereas Daubenton’s
bat Myotis daubentonii was found hunting over all waterways regardless the
pollution level.
