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?
What are the potential ecological consequences for Denmark's insect populations and agricultural sectors if bat populations continue to decline due to WNS?
In what ways do the foraging and navigation behaviors of key pollinators differ between the dense canopy layers and the ground-level environments where traditional mist nets are placed?
