While we debate whether the durian is the
best or worst food on the planet, it turns out this wonderful oddity requires
healthy populations of flying fox for survival

Durian. Depending on whom you talk to it’s
either the most beloved or the most despised fruit on the planet. It suffers no
moderation, no wishy-washiness. It is the king of fruits or the worst thing
you’ve ever tasted. Due to its potent odour – delicate and sweet to its
advocates and sewage-like to its detractors – durian has been banned from
airplanes, subways, and hotels (though punishments appear light if
non-existent). But a recent study in Ecology
and Evolution finds there may be no durians at all without bats: big,
threatened bats. The scientists found that flying foxes – bats in
the Pteropus and Acerodon genus and the largest in the
world – are likely vital pollinators for the polarising durian.
“We already knew that flying foxes feed on
durian flowers, but there was this unsubstantiated belief, even among some
researchers, that flying foxes just destroyed the flowers,” said Sheema Abdul
Aziz, the lead researcher on the project that was done as part of her PhD at
the Muséum National d’Histoire Naturelle in France. “It doesn’t help that a
durian flower only blooms for one night, then falls off the tree naturally,
regardless of whether it’s been pollinated or not. When people see all the
flowers on the ground in the morning, they think it’s the bats.”
