BEIJING, Nov. 28 (Xinhuanet) -- Scientists predict
that Britain's toad population could face extinction in some areas within 10
years due to an infectious fungal disease Batrachochytrium dendrobatidis, media
reported Wednesday.
The big unknown is just how long
the fungus, which lives on the skin of host amphibians, can survive on its own
in water. Scientists fear it may be a very long time.
"We start to see dramatic effects if the chytrid
(fungus) lives for longer than seven weeks outside the host," said Mat Fisher of
Imperial College in UK.
"We strongly suspect that it can live for longer
because of the devastating effect it has had elsewhere, and the new
mathematical models show that this would be very bad news for toads in this
country."
If the fungus is able to live outside the host for a
year, there would be a severe decline in the overall population of the European
common toad (Bufo bufo) in Britain and, in some places, extinction in 10 years.
The disease has already destroyed entire amphibian
populations in Central and South America, and Australia, and is a growing
problem in some parts of Europe. Scientists have linked its spread to global
warming.
