Dr Claire Concannon follows scientists into the bush, over rivers, back to their labs and many places in-between to cover the most fascinating research being done in Aotearoa New Zealand.

  • 1905 - The fight for the forest and the fernbird

    About two hours south of Dunedin, in the Catlins, the Tautuku and Fleming rivers flow into the sea at Tautuku beach. Covered in native bush from headwaters to the ocean, this special catchment is home to many native, and some threatened, plants and animals. But there’s an ongoing battle. Browsing animal such as deer and pigs are destroying the undergrowth, while feral cats and stoats are predating on critters such as the mātātā, the South Island fernbird. We meet some of the people fighting back.

  • 1904 - Lead bullets - a health risk for humans and kea

    Every year in New Zealand, recreational hunters shoot more than half a million wild game. Most are shot with lead-based ammunition. Now, researchers are investigating what happens to that lead, and how much of it is getting into the food chains of humans and the endangered kea. Alison Ballance speaks to scientists at Nelson-Marlborough Institute of Technology, and kea conservationists and predator control experts at the Department of Conservation to learn more.

  • 1903 - Can birds adapt their nest building for a warming world?

    To keep their eggs safe, some birds build simple cup-shaped nests. Others craft elaborate fully enclosed domes, with porches, fake entrances and ledges. But is this intricate construction of nests a set, encoded behaviour? Or can birds adapt in different conditions? Researchers are keen to learn about flexibility in nest design, to better understand how different species might be able to respond as the climate changes.

  • 1902 - Why we are still monitoring the ozone hole

    Almost 40 years on from the first reports of the Antarctic ozone hole, and 35 years since the Montreal Protocol to ban CFCs came into effect, what’s going on with the ozone hole? How does it form? How do we measure it? And having solved the CFC problem, why are we still monitoring ozone so closely? Claire Concannon heads to NIWA's Atmospheric Research Station in Lauder, Central Otago, to find out.

  • 1901 - Looking after our four-legged friends

    We love our four-legged friends. It’s estimated about a third of New Zealand households share their home with at least one dog, and two thirds of dog owners consider their furry friends to be family members. Some dogs work, others keep us company, make us laugh, get us walking twice a day, and shower us with unconditional affection….. But are we looking after all their needs? Claire Concannon speaks with a dog welfare expert about the science behind how we know our dogs love us, and what to do to make sure we are looking after them.
