Irony.. shutdown regulations.. then this: Bees' foraging for flowers 'hampered by diesel exhaust'

have you tried.. cough cough.. to ever breath on a busy 6 lane intersection.. in urban American .. w/no breeze.. cough ..


"We saw that there was loss of two of the components [of the floral odour mixture]," Dr Newman said.

The two odour chemicals that were "lost" had chemically reacted with a component of the diesel exhaust, mono-nitrogen oxide, known as NOx.

Having worked out how the pollution affected the chemistry of floral scents, the team set out to discover if the bees were affected by this change.

"Bees need to decipher the chemical messages they're getting [from flowers] to be able to home in on the flowers they know will give the best yield [of nectar]," said Dr Newman.

The pollinators, she said, learned to recognise the scents of nectar-rich flowers and this enabled them to forage more efficiently.
