Sampling optimization for molecular biosecurity surveillance – results from an expedition onboard the Robert C. Seamans (SEA, Woods Hole)

11/03/2021

In February 2020, our postdoc Ulla von Ammon embarked the Robert C. Seamans sailing ship to collect samples for comparing different sampling approaches. The first results of this study were recently presented at the DNAQUA International Conference.

Chasing eDNA signal of the Mediterranean fanworm in the Bay of islands

08/11/2020

We have started to employ modelling approaches to better understand and predict the dispersal of eDNA in the marine environment. Learn about our first field sampling campaign for testing whether the developed model can robustly predict where and when in the tidal cycle eDNA can be detected.

Right on-the-spot! How a human biologist became engaged in developing a rapid molecular test for marine pest detection

30/10/2020

Learn how Martin Zirngibl is contributing his knowledge and skills gained in a human biology field to developing a rapid and easy-to-apply in-field test for the Mediterranean fanworm detection.

Understanding habitat features of native mussel reefs

29/09/2020

Our project is making a start using the endemic, green-lipped mussel (kutai) to develop artificial surfaces that are attractive to native species and make them want to settle and stay for the long haul. Such surfaces can then be incorporated into coastal infrastructure, a process referred to as ‘ecological engineering’.

Crack open the bubbles – it works!

25/09/2020

Our recent experimental trials demonstrate that bubble streams are highly effective in controlling biofouling accumulation on experimental surfaces, and we are now keenly focused on developing operational systems to deploy in New Zealand’s ports and marinas

Better ways to capture DNA and RNA from water – collaboration with Dr. Holly Bowers from Moss Landing Marine Labs

22/09/2020

Holly Bowers joined our group as a visiting researcher and worked with the DETECT and ECONOMICS & DECISION-SUPPORT teams to define better (and more efficient) methods to capture nucleic acids (environmental DNA and RNA) from marine waters.

Sampling for biosecurity onboard the Robert C. Seamans (SEA, Woods Hole)

05/03/2020

Our PostDoc researcher Ulla von Ammon has taken part in the SEA Semester® research cruise organized by the Woods Hole Oceanographic Institution. Ulla shared with us challenges and exciting moments experienced during the expedition. Do you want to learn more about how does it feel to be a molecular scientist on a sailing ship?

Release and degradation of environmental DNA and RNA in a marine system

15/02/2020

A paper by Susie Wood and colleagues presents the results of an aquarium experimental study, where eDNA and eRNA shedding rates and degradation were investigated for two marine invasive species.
