“…Detection of IMS on their transport vectors or upon incursion is often a challenging task, as dispersive stages of many IMS such as larvae, cysts, eggs, and fragments are di cult to identify. This material often lacks distinct morphological features that enable unequivocal identi cation (Carvalho et al 2023). Improved identi cation and control measures for IMS have become available in the past two decades (Wan et al 2021;Castro et al 2022).…”

The global marine ecosystem is changing rapidly as the result of biogeochemical cycles and ecosystem structure being altered by industrial civilization. Invasive marine species (IMS) are one of the most damaging regional consequences of human activity, and one of the most easily attributable to specific processes. This makes IMS introduction one of most tractable threats for management with appropriate policies. Once established, a different set of policies are required either to restrict IMS spread, or to attempt local eradication. The key ecosystem management tool for IMS damage mitigation is rapid, widely deployable IMS detection. Environmental Nucleic Acids (eNA), combining environmental DNA (eDNA) and environmental RNA (eRNA) analyses, have emerged as valuable tools for sensitive, cost-effective and readily deployable detection of IMS. Methods for IMS detection by eNA are still being developed through a widespread and active research community, so identifying the limitations of current processes will help prioritise eNA-based IMS detection research. We analysed and synthesised the opinions of expert marine ecosystem managers and researchers in Australia and New Zealand about the knowledge gaps and research needs for eNA-based IMS detection. This synthesis was placed in context with current research literature on what eNA technologies are currently providing as an IMS management tool; what problems exist with the current technology; and what could be done to improve this general approach. Our analyses produced a list of priorities that chart a path towards the best possible systems for IMS detection by eNA - the eNA Utopia.

Man‐made environments such as ports and marinas are gateways for many marine non‐indigenous species (mNIS) transported via shipping worldwide. These habitats are often the focus of biosecurity programs for the surveillance of mNIS, but there have been few studies investigating the distribution of biofouling communities in natural habitats and nearby artificial habitats. Here, following a DNA metabarcoding approach, we tested for differences in spatio‐temporal trends of biological pioneer communities established after one‐week colonization between a port, a marina, and coral reefs using two different matrices (PVC panels and water samples) in the central Red Sea. In addition, we aimed to investigate differences in the prevalence of mNIS between man‐made and natural habitats during the summer and winter seasons, and whether the number and patterns of mNIS differed between the port (an active historic port subjected to intense shipping traffic) and the marina (a small recently developed marina utilized by small and medium research vessels). The community structure from samples collected at the two coral reefs showed greater similarity to each other compared to that obtained from the port and the marina. A total of 29 mNIS were detected across all sites, of which 16 were reported in the Red Sea for the first time, with Jeddah port hosting 28 mNIS. By applying standardized methodological approaches, this study provides comparable data regarding the monitoring of introduced and invasive species, particularly within the data‐poor Red Sea, a major shipping corridor. This study serves as the foundation for implementing a robust and rapid baseline monitoring system to assess native biodiversity and facilitate the early detection of NIS.
