    Going for eradication - Predator free South Westland

    Since 2018 there's been a massive effort underway to clear over 110,000 hectares of South Westland of possums, rats and stoats. As the pest numbers have dropped the native flora and fauna seem to have flourished. The eradication stage is now nearing completion, and the focus is switching to maintenance. What will it take to keep the pests out long-term? And what can be learned from this large-scale project that could be used elsewhere in Aotearoa?

    Insect vibes

    Some insects communicate using a secret language that we can’t sense – a language of vibrations. Now researchers at the Bioeconomy Science Institute are starting to decode what insects are saying to each other. They hope to harness this knowledge to develop new, chemical-free methods of pest control to help farmers and growers. Sign up to the Our Changing World monthly newsletter for episode backstories, science analysis and more. Learn more: Insects can also be recruited to help. For example, insects can be released into New Zealand for biocontrol in the effort to combat invasive weeds.While we often talk about the impact of invasive mammals on New Zealand’s bird life, they are also a problem for native insects too.We’ve got some invasive pest spiders here too, but researchers are trying to figure out if they can trap them by developing a special spider perfume.Guests: Dr Mark MacDougall, Bioeconomy Science InstituteDr Lloyd Stringer, Bioeconomy Science InstitutePete Mundy, Castle Rock OrchardsDr Rachael Horner, Bioeconomy Science InstituteDr Bethan Shaw, Bioeconomy Science InstituteGo to this episode on rnz.co.nz for more details

    Sight in the womb

    When do humans begin to interact with the world, and develop our sense of self? When we are born? Or might it start even earlier than that? Our visual systems are a key way that we perceive the world. New findings from the University of Waikato have shown that light can enter the womb and that we might already be learning about the world before we arrive in it. Sign up to the Our Changing World monthly newsletter for episode backstories, science analysis and more. Learn more: Listen to Our musical minds to learn why, to psychologists, humans’ musical ability is just weird.Like our sense of vision, our ability to hear also involves physical inputs from the world around us combined with the processing and prior knowledge of our brains. But sometimes things can go a bit awry, such as happens for those with tinnitus.Our visual system is evolved for daylight, but what about those creatures that live in the deep darkness, such as squid.Professor Vincent Reid’s early research in this area was covered by RNZ podcast ‘This Way Up’ in 2017.Hear more from William Ray in the award-winning Black Sheep podcast series, or in a recent Our Changing World episode about the Flowers of the Underworld.Guests: Professor Vincent Reid, University of WaikatoAssociate Professor Jacob Heerikhuisen, University of WaikatoWilliam Ray, Janella Espinas, James Espinas RayGo to this episode on rnz.co.nz for more details
