Researchers from the MANAGE AND RESPOND and ECONOMICS AND DECISION SUPPORT teams have joined forces to work towards an understanding of the factors that encourage or discourage hull cleaning behavior of the recreational boat owners in New Zealand.
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.
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.
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.
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.
This review and synthesis collates the range of methods and tools that exist or are emerging for managing biofouling on submerged static artificial structures for a variety of sectors, highlighting key criteria and knowledge gaps that affect development, and uptake to improve operational and environmental outcomes.
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.
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.
An open-access peer-reviewed publication describing a series of laboratory and field trials that examine the efficacy of continuous bubble streams in maintaining artificial substrates free of macroscopic biofouling and demonstrating that this treatment approach is effective on surface types commonly used in the marine environment.
