Climate change has increased the spread and severity of fatal disease caused by ranavirus which infects common frogs (Rana temporariaIn the UK, according to research conducted by ZSL Institute of Zoology, UCL and Queen Mary University of London published in Global change in biology.
Historical trends in mass mortality events attributed to the disease
Found to match the pattern of increased temperatures recorded throughout
Recent decades, with disease outbreak predicted to be more severe,
Be widespread and more widespread throughout the year
In the next few decades, if carbon emissions continue to do so
The research conducted by international conservation charity
(Zoological Society of London), UCL, Queen Mary University of London and
University of Plymouth used a three-pronged application involving cells
Cultures, live models and historical data from the Met Office and
Froglife's Frog Mortality Project, with the research demonstrating that
Warm weather, where temperatures reach 16 ° C, dramatically increase them
Risk of Ranavirus causes a disease outbreak in common frogs.
The findings help explain the seasonality of the disease, including
Incidence of picking during the hot summer months
Climate change could see outbreaks becoming more frequent from April
October. Disease outbreak in the spring can result in deaths
Large numbers of tadpoles, which may have populations
Survival. Until now, Ranavirus disease is largely restricted
England, but as average monthly temperatures increase to exceed 16 ° C in
More changed over longer periods, as predicted by the IPCC's
Notch-emission model, most of the disease is likely to spread
The UK in the next 50 years.
Dr. Stephen Price, lead author of the ZSL Institute of Zoology
UCL said: "Climate change isn't something that's just happening in."
Remote places – this is something real and present that it already had
Hard-to-predict impacts on wildlife at our own back gardens here
"A number of scientists have been alerted to the fact that
Climate change may increase the spread of disease, but this is one of
The first studies that provide strong evidence of climate impact
Change in wildlife disease and help explain how it can facilitate
The spread of Ranavirus across the UK. "
ZSL scientists suggest that frogs may be better at understanding
Infection if they have areas where they can cool – Adding log
Piles, vegetation or nearby shady patches as well as keeping ponds deep
Will help reduce the height of sun exposure of frogs, and so on
Reduce the growth rate of the virus.
Professor Trenton Garner of ZSL's Institute of Zoology said: "Many
Studies in amphibious disease cannot do much further than we say, "we have a."
Problem & # 39 ;. This research offers a number of options for mitigation;
However, this is just a short-term solution of course – if we don't
Eventually, slow and reverse person-driven climate change, me
Unfortunately, we can only expect things to get worse for our amphibians. "
