Scientists say that increasing number of houseflies that arrive in Antarctica on ships are surviving as the continent warms up. Their growing population can introduce deadly pathogens that could have a harmful effect on indigenous lifeforms.
As temperatures rise and glaciers retreat, particularly in the Antarctic Peninsula, its coastal areas are being colonized by invading mosses and insects like the common housefly, which are posing a conservation threat to the continent’s distinctive ecosystems.
Dominic Hodgson of the British Antarctic Survey said that introduction of houseflies in Antarctica is a perfect example of how global warming and human interference is changing the continent’s fragile ecosystem.
It comes in on ships, where it thrives in kitchens, and then at bases on the continent. It now has an increasing chance of surviving in the Antarctic as it warms up, and that is a worry. It is still …
