Bees rely on flower patterns, study finds
"Our findings suggest that flowers don't need to evolve too many petal colours, because they can use patterns to diversify their displays." - Professor Natalie Hempel de Ibarra.

Colour is not the only thing used for identification.

Research carried out by the University of Exeter has found that honeybees can very effectively distinguish between different flowers using pattern as well as colour.

With their low-resolution vision, honeybees can only see the patterns on a flower clearly within a few centimetres.

However, the new study has found that bees usually consider pattern, suggesting that it is not just colour that leads them to flowers.

The research team tested bee behaviour and built bee's-eye-view simulations to understand how bees view flowers, and how they distinguish between them.

Professor Natalie Hempel de Ibarra, lead author on the study, explained: "We analysed a large amount of data on plants and bee behaviour.

"By training and testing bees using artificial patterns of shape and colour, we found they relied flexibly on their ability to see both of these elements.

"Showing how insects see colour and learn colour patterns is important to understand how pollinators may, or may not, create evolutionary 'pressures' on the colours and patterns that flowers have evolved.

"Our findings suggest that flowers don't need to evolve too many different petal colours, because they can use patterns to diversify their displays so bees can tell them apart from other flowers."

Entitled 'The role of colour patterns for the recognition of flowers by bees', the paper is available to read in Philosophical Transactions of the Royal Society B.

Birmingham Dogs Home makes urgent appeal

News Story 1
 Birmingham Dogs Home has issued an urgent winter appeal as it faces more challenges over the Christmas period.

The rescue centre has seen a dramatic increase in dogs coming into its care, and is currently caring for over 200 dogs. With rising costs and dropping temperatures, the charity is calling for urgent support.

It costs the charity £6,000 per day to continue its work.

Fi Harrison, head of fundraising and communications, said: "It's heart-breaking for our team to see the conditions some dogs arrive in. We really are their last chance and hope of survival."

Avian flu confirmed at premises in Cornwall

A case of highly pathogenic avian influenza H5N1 has been detected in commercial poultry at a premises near Rosudgeon, Cornwall.

All poultry on the infected site will be humanely culled, and a 3km protection zone and 10km surveillance zone have been put in place. Poultry and other captive birds in the 3km protection zone must be housed.

The case is the second avian flu case confirmed in commercial poultry this month. The H5N5 strain was detected in a premises near Hornsea, East Riding of Yorkshire, in early November. Before then, the disease had not been confirmed in captive birds in England since February.

The UK chief veterinary officer has urged bird keepers to remain alert and practise robust biosecurity.

A map of the disease control zones can be found here.
