Abstract There is an urgent need for improved monitoring approaches to rapidly and accurately assess sea cucumber populations at ecologically relevant scales. Timely surveys are critical for informing effective fisheries management and decision-making. Traditional surveys, undertaken via snorkelling, manta tows, or SCUBA, are limited to shallow and accessible areas; however, sea cucumbers inhabit a broad range of depths, including areas beyond safe diving limits and exposed shallow waters inaccessible by boat. To overcome these limitations and increase the rapidity of field collection, we propose the use of remote sensing technologies to survey sea cucumber populations across a range of depths. Here, we evaluated the effectiveness of aerial drones and in-water remote operated vehicles (ROVs) for assessing sea cucumber species and abundances across various depth ranges (< 50 m) on the Great Barrier Reef, Australia. Aerial drone orthomosaics and ROV video footage were compared to more traditional snorkel and SCUBA-based assessments conducted at similar depths. The vast majority of pairwise comparisons between in-water ROV video counts and snorkel or SCUBA assessments found no significant differences in sea cucumber assemblages. Counts from aerial drone-derived orthomosaics, however, were significantly lower, counting approximately half as many sea cucumbers as snorkel counts. This was largely attributed to poor weather during the drone surveys. Remote methods were significantly faster in the field for surveying a given area than traditional methods. Given that towed ROVs can efficiently cover a broader depth range and aerial drones are effective for survey shallow areas under suitable weather conditions, we recommend using a combination of aerial drones and towed ROVs to survey sea cucumbers, with tool selection guided by prevailing weather conditions. This approach offers the advantages of collecting multiple types of data from a single data source, vastly increasing survey efficiency, and providing a historical record for future assessments. The methods have the potential to be used to survey other benthic–associated species.

Heated tobacco products (HTPs) are electronic devices that heat tobacco sticks to temperatures much lower than those which cause pyrolysis and combustion in cigarettes. While this electrical heating causes the formation of an inhalable aerosol which contains nicotine, the aerosol from HTPs contains significantly fewer and lower levels of the harmful and potentially harmful chemicals found in cigarette smoke. As a result, HTP use potentially conveys reduced risks to health compared to cigarette smoking. While this relative reduction in individual health risk is becoming clearer, what is less certain is the impact of HTPs on overall population‑level health, taking into account both the potential positive impact on adult smokers who completely switch to using HTPs and any unintended impacts such as use by tobacco non‑users and particularly by youth.The aim of this scoping review was to collate and evaluate the published scientific evidence to date, with acut‑off of 1 January 2024, investigating the impact of HTPs on population‑level health.This evaluation suggests that HTP use is almost exclusively observed among those with a history of cigarette smoking, and there is a growing body of evidence for the ability of HTPs to provide support for adult smokers to transition away from cigarette smoking, in the absence of any significant "gateway" into tobacco use initiation. Many studies have reported a significant degree of dual use of cigarettes and HTPs, and efforts to assess the reasons for such patterns of use, whether these provide overall exposure reductions, and whether dual use acts as a bridge towards a complete transition away from cigarette smoking, requires further investigation. In addition, correction of the widespread and increasing misperceptions of HTPs among adult smokers is recommended to promote HTP uptake as a potentially less harmful alternative to smoking in this population.

Vascular calcification is a recognised source of morbidity among mid-age and elderly subjects. Its development follows classical mineralisation pathways, inhibited by acidosis.

Despite record levels of domestic production, forecasters are predicting that the east coast Australian gas market will remain tight in 2019. The introduction of the Australian Domestic Gas Security Mechanism (ADGSM) by the Federal Government in 2017, and the proposal announced by the Australian Labour Party (ALP) to bolster the mechanism, have again thrust the issue of political intervention in the export gas market into sharp focus. This paper provides an overview of the current regulatory intervention at the state and federal level, and looks back at the history of controls imposed upon the Australian gas export market. The paper is divided into two parts: Part 1, which looks at current regulatory controls engaged by various State and Federal governments: (a) the development and implementation of the ADGSM; (b) the development and implementation of the Queensland Government’s Prospective Gas Production Land Reserve policy (PGPLR); and (c) the Government of Western Australia’s (WA Government) domestic gas policy. The paper also reviews policy announcements made by the ALP in the lead up to the 2019 Federal election. Part 2 provides a broad overview of the history of controls on gas exports in Australia, from the embargo on exports from the North West Shelf between 1973 and 1977, through the increasing liberalisation of Australian energy policy during the 1980s and 1990s (and the associated conflict with state concerns of ensuring sufficiency of the domestic supply of gas), up to the removal of federal controls on resources exports (including liquefied natural gas) in 1997.

SummaryThe UK fishing sector has been under the spotlight since the beginning of the Brexit debate. Political commentators claimed that up to 90 per cent of British fishers supported Brexit as they considered the UK was disadvantaged compared to other EU Member States. Their main grudge is about the equal access that all Member States have had to all EU waters – with the exception of territorial waters, up to 12 nautical miles from the coast – since the formal inception of the Common Fisheries Policy (CFP) in 1983. Combined with what they perceive to be an unbalanced allocation of fishing quotas, this legal framework is thought by the UK fishing industry to be the main reason for the poor management of EU fisheries, which could be terminated following Brexit thus regaining the UK's status as an independent coastal state. The key issue addressed in this article is the possible reallocation of fishing opportunities within British waters. It outlines the current allocation system and summarises the views of major stakeholders. This is complex as historical fishing rights may or may not be acknowledged but it remains that the UK fishing industry needs access to EU markets and EU labour to bring the fish to value.

During the late nineteenth century huge numbers of rabbits swept across south-east Australia causing widespread damage. Farming and grazing sheep and cattle became difficult on many properties, but the rabbit industry boomed. For farmers and graziers who tired of efforts to reduce rabbit numbers by shooting, trapping or poisoning, the solution seemed to lie in total extermination with a biological agent. In the late 1880s, the New South Wales (NSW) government took up their cause and offered a £25,000 prize for a biological remedy for the rabbit problem, but the prize was not awarded. Twenty years later farmers and graziers took matters into their own hands and hired the noted French scientist, Dr Jan Danysz, to provide a biological agent to exterminate the rabbits. Danysz's employment and experiments became a battle between sectional interests. Rural workers, who had begun harvesting rabbits, and rabbit industry investors opposed the Danysz virus for financial reasons, while farmers and graziers supported it because they wanted the rural landscape to support their traditional economic practices. While the NSW government supported landowners, other state governments and the federal government opposed the experiments.
