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.
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.
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.
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.
An open-access peer-reviewed publication aimed to facilitate dialogue and innovation within this sector by reviewing current approaches for sample collection, post-sampling capture and concentration of eDNA, preservation, and extraction, all through a biosecurity monitoring lens.
An educational article on environmental DNA was published in Frontiers for Young Minds journal - a unique open-access scientific journal aimed at younger audiences with scientific articles reviewed by a board of kids and teens.
