Trouble in Paradise

Слухати в додатку
Science isn't just about pursuing knowledge. Some researchers literally chase down their findings across land, sea and sky. This four-part series of immersive radio documentaries, made for the BBC World Service by the Australian Broadcasting Corporation, is where science meets adventure.

Each story follows a different group of scientists on a fascinating, high-stakes journey. The audience will travel deep into the outback and far across the Pacific Ocean.

This is science on the run.

The four documentaries are presented by four of Australia's best young science journalists. Each one takes the listener somewhere they would never otherwise get to visit, in the company of memorable characters – from Indigenous elders and researchers to retired air-force pilots and fossil-loving farmers.

Programme Three: Trouble in Paradise

The atoll of Tetiaro is a string of tiny islands in French Polynesia, about 60km away from Tahiti. The islands – known as ‘motus’ to local Polynesians – are unique ecosystems that are crucial nesting sites for native seabirds.

But invasive species threaten to disrupt these fragile environments – a fate seen across many islands in the Pacific.
Rats arrived with early human settlers and have driven bird species off some of the islands. Meanwhile introduced mosquitoes have thrived in the warm conditions, and now act as vectors for diseases such as the Zika virus.

Rat eradication experts have travelled to one of the uninhabited islands in the atoll, called Reiono, to attempt an experimental eradication of thousands of rats with one mammoth poison bait drop. They’re also using this as an opportunity to better understand why eradication attempts have been less effective on tropical islands.

At the same time, on another island in the chain called Onetahi, researchers are releasing swarms of sterilised male mosquitoes to try to rid this motu of the disease-carrying pest.

Join Carl Smith from ABC Australia for the third episode of The Chase: a special four-part series about science on the run.
