Development of DNA based methods to detect taonga species

Konstanze Steiner and Georgia Thomson-Laing talk about the development of DNA based methods to detect taonga species

Lakes380 researchers Konstanze Steiner and Georgia Thomson-Laing recently talked to Cawthron Radio about the development of DNA-based methods to detect taonga species that live in New Zealand lakes.

Konstanze and Georgia have been developing DNA-based methods to detect tuna (eel) and kākahi (freshwater mussels) in environmental samples. By extracting DNA shed from the tuna and kākahi into the water and sediments of lakes, they are able to determine if these native aquatic species currently live in the lake and how abundant they are. These methods provide a new avenue to map the distribution of these species at scale not previously possible. Once their methods are fully optimised they hope to use them to explore historic populations of these species from lake sediment cores. Check out the interview here.

Sampling for fish eDNA in lakes

Check out these new eDNA posters! eDNA is an ama Check out these new eDNA posters! 

eDNA is an amazing new tool that can help us understand and protect the taiao (environment) - but it can't do everything. It needs to be used to complement other techniques and aligned with Indigenous and local knowledge. These new posters highlight these benefits and provide suggestions on some questions to ask before launching into an eDNA based project!

When working with eDNA projects we like to co-design the project with our partners. We also love sharing our knowledge and helping train the next generation of scientists to become sentinels of the taiao.
