The Gemmell Lab actively explores the use of environmental DNA (eDNA) as a non-invasive tool to survey biodiversity, and to detect known pest species and emergent biosecurity threats. We cover land, sea, and air – and maybe space too if we get the chance.
Most of our research seeks to protect and enhance the delicate and unique biodiversity of New Zealand, and to protect the productive systems upon which the New Zealand economy still strongly depends. We develop and apply new approaches for understanding biodiversity and identifying biosecurity threats whether these be rats in our conservation estate or marine invasive species that are affecting our ports and aquaculture systems. You can read more about our individual projects here:
- Gracie Kroos’ PhD research focuses on the use of eDNA biomonitoring in terrestrial ecosystems to detect terrestrial pests, in particular invasive wallaby species in New Zealand.
- Benjamín Durán-Vinet’s Phd research focuses on the uses of CRISPR endonucleases to detect specific traces of eDNA/eRNA that may help us to elucidate the presence and abundance of non-indigenous species and/or harmful algal bloom species.
- Nicolás Restrepo Garzon’s PhD research focuses on the use of eDNA to study kelp forests, aiming to understand ecosystem health and contribute to the protection of endangered marine species.
- Jackson Treece’s research involves developing point-of-need diagnostic devices, Antarctic sponge eDNA analysis for the Marine Biosecurity Toolbox, and develping a Caulerpa sp. seaweed detection protocol.
We are part of successful research consortia working in these domains.
Current projects include: Toka Ākau Toitū Kaitiakitanga which aims to better our understanding coastal reef ecosystems and how they may be affected by climate change/land development.
Projects and programmes where we have been involved include:
