Are certain classes of pesticides more detrimental to the specific lifecycle of midges and mosquitoes than others, and how does this impact the seasonal availability of food for the bats?
Beyond food scarcity, is there a risk of bioaccumulation, where pesticides become more concentrated in the bats' systems as they consume contaminated aquatic insects?
If bats increase their hunting activity near polluted streams, does this indicate they are searching more intensely because food is scarcer, or are the pesticides altering insect behavior in a way that makes them more visible?
Are there any current or proposed conservation interventions, such as managing cave temperatures or applying topical treatments, to mitigate the impact on Danish bats?
