Where do mussels like to call home?

To find out what features of the reef attract mussels, we dropped baby green-lipped mussels on several types of 3D printed tiles representing rocky reef structures in seawater tanks and saw where they went. This experiment will help us designing eco-engineered structures that would give this native species a competitive advantage over invasive species on artificial structures.

Mapping nationwide movements of New Zealand’s recreational vessels

The MANAGE & RESPOND TEAM developed a web-based survey that uses interactive maps to capture the movement of recreational boats in New Zealand. The collected data will be used to create a network model of recreational vessel movements to understand places of particular importance for biosecurity pathway management and response.

The increasing issue of coastal hardening and its associated socio-economic risks

We mapped coastal hardening associated with 30 international urban centres and, using machine-learning algorithms, developed a model to forecast the regional expansion of 4 globally common coastal infrastructure types. We applied this model to New Zealand for anticipating regional distributions and future hotspots of socioecological risks over a 25-year period.

From North to South – scientists set sail for two collaborative expeditions

In 2021, the DETECT team had a big year on the water participating in two research expeditions, in two very distant and ecologically different areas of Aotearoa: Northland and Fiordland. These expeditions allowed us to collect valuable data on distribution of the high-profile non-indigenous species while testing our optimized molecular surveillance tools and protocols.

A framework for quantifying of marine biosecurity risk factors associated with common vessel types

This publication synthesizes empirical data on a wide range of vessel types and characteristics to develop a framework that allows systematic quantification of the relative risk of NIS transfer by common commercial vessel types. A potential application of the framework for assigning a relative risk level for New Zealand ports, based on the arrival frequencies of different vessel types, is presented.

Lessons from an international cross-laboratory experiment on delivering reproducible metabarcoding data

Acknowledging the need for a coordinated effort to accelerate the uptake of high-throughput sequencing (HTS) based tools for biodiversity surveys and biosecurity applications, an international cross-laboratory experiment was conducted to evaluate replicability of a metabarcoding protocol and explore how laboratory-based variance in sample handling and processing impacts biodiversity assessments.
