This story is not particularly agricultural, but I couldn’t resist it. Brazilian researchers extracted the essential oils from a Piper sp commonly eaten by bats and then smeared the stuff on plastic fruits, which they then distributed in areas of damaged rainforest. The bats were attracted to the fake fruits, though they wouldn’t normally fly in degraded forest. Why go to all this trouble? Because the bats spread lots of seeds via their faeces, and could thus be used to restore the vegetation.
