Catch up on the research highlights from our third programme year, which we just collectively celebrated at Patuharakeke Iwi's Takahiwai Marae in Northland!
A recent study explored new methods for marine surveillance using eDNA. The researchers compared traditional filtration methods with passive sampling and self-contained DNA extraction. Passive sampling using materials like artificial sponges and fishing nets showed similar results to active filtration in detecting fish diversity. The study suggests that passive sampling is a promising approach for eDNA monitoring and contribute to improving non-invasive monitoring techniques for marine environments.
Watch the video voiced by doctoral candidate Joe Rawlinson, which describes the problem of marine biofouling, existing control options, and nature-inspired antifouling solutions.
The results of our recent experimental study suggest that bio-based polymers and composites with increased potential for biodegradability, recyclability, and aptitude for the selective recruitment of marine invertebrates might offer a sustainable alternative to conventional polymers.
Our programme's recreational vessel survey received over 1,800 individual responses from throughout the country. To our knowledge, they represent the largest recreational vessel movement dataset ever collected.
On 20 June, around twenty biosecurity and technical diving specialists from around New Zealand attended a 1-day workshop in Manukau to discuss boat biofouling and the Level of Fouling (LOF) rank scale. The workshop addressed the range of approaches for vessel hull surveys in NZ and the design of operational and training resources for use of the LOF scale.
Learn about the new species-specific recombinase polymerase amplification (RPA) assay designed for the fanworm detection from eDNA samples and insights on its applicability for citizen scientists-driven biosecurity surveillance.
Watch Michelle's talk on experimental study of environmental DNA & RNA fate for biosecurity applications, presented at the first Australia & New Zealand eDNA webinar.
An experimental study was conducted to test different filter membranes for capturing eDNA/eRNA in the context of cost/time effort and cell fractions encountered in nature. For the first time a formal efficiency modelling was applied in eDNA and eRNA research to assist decision-making around an optimized sampling approach.
Learn why our scientists design Japanese obstacle courses for predatory snails and investigate nutritional value of marine biofouling.
