Quote:
Zoo curator Gerd Noetzhold said he had discovered that zoos throughout Europe and further afield had encountered the same problem, but no-one knew why.
One expert suggested it could be caused by climate and the diet of the bears, whose native habitat is South America.
The bears come from the Andean mountains of Ecuador, Peru and northern Bolivia.
