Getting out in the field and the lab to bring you New Zealand stories about science, nature and the environment. With Alison Ballance.
PhD student Kiamaia Ellis describes crayfish as a ‘vulnerable tāonga species'. Local iwi in Tauranga believe the crayfish population is decreasing because of urban, industrial and harvesting pressures. But Kiamaia is keen to be a part of the solution, so she's studying the resilience of pēpi kōura / baby crayfish. She wants to understand how these tiny species – that take eight years to become an adult – are able to thrive based on a kaitiakitanga or guardianship approach.
