Mapping the voices: Spanish boat owners and marina operators on non-indigenous marine species—knowledge and key informantsNARA Subscribed
The public need to be aware of non-indigenous species (NIS) and how they spread to effectively manage this marine biosecurity risk. In most countries, the management of biosecurity risks associated with recreational boating relies exclusively on vessel owners and marina managers engaging in pro-environmental behaviours. To understand if this management approach is feasible, stakeholders’ perceptions first need to be identified...
Remotely Sensed Fire Heterogeneity and Biomass Recovery Predicts Empirical Biodiversity ResponsesNARA Subscribed
Aim To compare field‐based evidence of plant and animal responses to fire with remotely sensed signals of fire heterogeneity and post‐fire biomass recovery. Location South‐eastern Australia; New South Wales. Time Period 2019–2022. Major Taxa Studied A total of 982 species of plants and animals, in eight taxonomic groups: amphibians, birds, fish, insects, mammals, molluscs, plants and reptiles. Methods We collated 545,223 plant...
Does non‐native diversity mirror Earth's biodiversity?NARA Subscribed
Aim Human activities have introduced numerous non‐native species (NNS) worldwide. Understanding and predicting large‐scale NNS establishment patterns remain fundamental scientific challenges. Here, we evaluate if NNS composition represents a proportional subset of the total species pool available to invade (i.e. total global biodiversity), or, conversely, certain taxa are disproportionately pre‐disposed to establish in non‐nat...
Marine ecosystems are under increasing pressure from human activity, yet successful management relies on knowledge. The evidence-based policy (EBP) approach has been promoted on the grounds that it provides greater transparency and consistency by relying on ‘high quality’ information. However, EBP also creates epistemic responsibilities. Decision-making where limited or no empirical evidence exists, such as is often the case i...
Offshore platforms, subsea pipelines, wells and related fixed structures supporting the oil and gas (O&G) industry are prevalent in oceans across the globe, with many approaching the end of their operational life and requiring decommissioning. Although structures can possess high ecological diversity and productivity, information on how they interact with broader ecological processes remains unclear. Here, we review the curren...

Marine biosecurity post‐border management: Developing incursion response systems for New ZealandNARA Subscribed
New Zealand's approach to marine biosecurity has been to integrate the pre‐border, border, and post‐border management actions so as to appropriately and effectively utilise resources. Prevention is clearly better than cure, consequently pre‐border and border management is paramount. There is, however, recognition that quarantine style controls result in leaky borders. Early detection of new invaders, coupled with appropriate i...
Marine biosecurity, the protection of the marine environment from impacts of non‐indigenous species, has a high profile in New Zealand largely associated with a dependence on shipping. The Ministry of Fisheries is the lead agency for marine biosecurity and is tasked with managing the risks posed by pests and non‐indigenous marine species. Much like the terrestrial environment, multiple pathways provide ample opportunities for...
