Australia: Climate change reduces Queensland's bat numbers

A central eastern Queensland mine has turned up bat fossils which show climate change has had a negative impact on the state's bat population.

Queensland University of Technology (QUT) PhD student Sandrine Martinez is currently sifting through what is the largest and best record of the state's southern most bat population from the late Pleistocene Epoch (beginning two million years ago and ending approximately 10,000 years ago).

The fossil deposits were uncovered by mining operations at Mt Etna, near Rockhampton.

They contain a succession of bat remains ranging from the late Pleistocene Epoch to the present and span the transition from full tropical rainforest habitats to the more arid environment that currently characterises the Mt Etna region.

Ms Martinez will compare information obtained from fossil data to the bat communities that still occur in the Mt Etna caves.

"What I've found so far is an overall decrease in species richness - today the Mt Etna caves are inhabited by five species of bat (excluding fruit bats) while in the late Pleistocene there were at least eight," Ms Martinez said.

Didymosphenia geminata, sometimes referred to as "rock snot," has been seen growing on rocks near Bloomfield, which concerns state biologists.

The algae can smother aquatic plants and destroy fish habitats.

Britain faces big freeze as Gulf Stream loses strength

The Gulf Stream currents that give Britain its mild climate have weakened dramatically, offering the first firm scientific evidence of a slowdown that threatens the country with temperatures as cold as Canada's.

The Atlantic Ocean "conveyor belt" that carries warm water north from the tropics has weakened by 30 per cent in 12 years, scientists have discovered. The findings, from the National Oceanography Centre in Southampton, give the strongest indication yet that Europe's central heating system is breaking down under the impact of global warming.
