Three phases of the Pacific Islands Project (1995–2010)

The Pacific Islands Project (PIP), funded by AusAid and managed by the Royal Australasian College of Surgeons (RACS), has progressed through three phases from 1995 to 2010. During this time, it has sent over 520 teams to 11 Pacific Island Countries, providing over 60 000 consultations and some 16 000 procedures. In addition to this delivery of specialist medical and surgical services that were not previously available in-country, the project has contributed as a partner in capacity building with the Fiji School of Medicine and Ministries of Health of the individual nations. By 2011, Fiji School of Medicine, which began postgraduate specialist training in 1998, had awarded 51 doctors a diploma in surgery (1 year), 20 of whom had completed their Masters in Medicine (4 years). PIP was independently evaluated on completion of every phase, including the bridging Phase III (2006–2010). The project delivered on its design, to deliver services, and also helped build capacity. The relationship established with the RACS throughout the project allowed Pacific Island graduates to access the Rowan Nicks scholarship, and the majority of MMed graduates received International Travel Grants to attend the Annual Scientific Meeting. PIP has been a highly successful partnership in delivering and building specialist medical services. Although AusAid contributed some $20 million over 16 years, the value added from pro bono contributions by Specialist Teams, Specialty Coordinators and the Project Directors amounted to an equivalent amount. With the emergence of Pacific Island-trained specialists, PIP is ready to move into a new phase where the agendas are set, monitored and managed within the Pacific, and RACS fulfils the role of a service provider. A critical mass of Pacific Island surgeons has been trained, so that sub-specialization will be an option for the general surgeons of the larger island nations.

Separate and invisible : a carceral history of Australian islands

This article examines the history of four islands used for incarceration in Australia: the ‘secondary punishment’ of convicts on Norfolk Island; the management and quarantine of indigenous people on Palm Island; the quarantine of all new migrants and visitors on Bruny Island; and the incarceration of enemy aliens on Rottnest Island. Incarceration has been used throughout Australia’s history as a method of social and political control, targeting categories of people perceived to pose a threat to the racial composition, social cohesion, or national security of the Australian community. By providing a space both separate and invisible to the community, Australia’s carceral islands served as a solution to a recurring problem for a young nation apprehensive about the composition, durability and security of its community. The human consequences of incarceration could be devastating.

Climate as a driver of population variability in breeding Gentoo Penguins (Pygoscelis papua) at the Falkland Islands

Detecting and predicting how populations respond to environmental variability are eminent challenges in conservation research and management. This is particularly true for wildlife populations at high latitudes, many of which demonstrate changes in popula

A bald encounter : hairless southern sea lion at the Falkland Islands

A hairless adult male southern sea lion (Otaria flavescens) was sighted at Sea Lion Island, Falkland Islands, on the 14th of August 2009. The sea lion was observed on several further occasions and was defending a small harem consisting of four females. To our knowledge, this is the first report of an apparently healthy sea lion being entirely hairless with the exception of vibrissae on the muzzle.

Subfossils of extinct and extant species of Simuliidae (Diptera) from Austral and Cook Islands (Polynesia): anthropogenic extirpation of an aquatic insect?

Subfossil head capsules of Simuliidae larvae have been recovered from swamps on Tubuai and Raivavae of the Austral Islands, and Atiu and Mangaia of the southern Cook Islands. For Tubuai and Raivavae it is likely that the simuliids are extinct, but a single simuliid species is extant on nearby Rurutu. For Atiu and Mangaia, extant simuliids have not been reported, but are known on Rarotonga. Well-preserved head capsules indicate that the Cook Islands subfossils are those of Simulium (Inseliellum) teruamanga Craig and Craig, 1986. For the Austral Islands, the simuliid from Tubuai is considered a variant of Simulium (Inseliellum) rurutuense Craig and Joy, 2000. That from Raivavae is morphologically distinct and is described here as a new species, Simulium (Inseliellum) raivavaense Craig and Porch. Humans arrived in Eastern Polynesia ca. 1,000 years ago resulting in the widespread destruction of lowland forest and conversion of wetlands to agriculture with implied consequences for the indigenous biota of these habitats. Here we consider that one such result was loss of freshwater aquatic biodiversity.

Population trends of Gentoo Penguins Pygoscelis Papua breeding at the Falkland Islands

The fourth archipelago-wide census of Gentoo Penguins Pygoscelis papua breeding at the Falkland Islands was conducted from 24 October to 8 December 2010. The number of Gentoo Penguins breeding in 2010 was estimated to be 132 321 ± 2 015, the highest number of breeding pairs recorded for this species at the Falkland Islands since the first survey in 1933. The global population of Gentoo Penguins is conservatively estimated to be about 384 000 breeding pairs, of which the Falkland Islands accounts for 34%, probably the largest component of the global population. Annually monitored study colonies accounted for 20% of the total number of Gentoo Penguin breeding pairs at the Falkland Islands in 2010 and proved to be a reliable proxy for archipelago-wide changes in the number of breeding pairs. Recent trends at annually monitored study colonies, combined with archipelago-wide trends, indicate that the number of Gentoo Penguins breeding at the Falkland Islands has increased between 2005 to 2010. However, annual monitoring data also revealed large inter-annual variability in the number of breeding pairs, which makes assessing systematic population changes challenging.

Two hundred years after a commercial marine turtle fishery: the current status of marine turtles nesting in the Cayman Islands

Large populations of marine turtles breeding in the Cayman Islands were drastically reduced in the early 1800s. However, marine turtle nesting still occurs in the islands. The present-day status of this nesting population provides insight into the conservation of marine turtles, a long-lived species. In 1998 and 1999, the first systematic survey of marine turtle nesting in the Cayman Islands found 38 nests on 22 beaches scattered through the three islands. Three species were found: the green Chelonia mydas, hawksbill Eretmochelys imbricata and loggerhead Caretta caretta turtles. Comparison with other rookeries suggests that the small number of sexually mature adults surviving Cayman’s huge perturbations may be impeding population recovery. This shows the need to implement conservation measures prior to massive reductions in population size.

Darumbal voyaging: intensifying use of central Queensland's Shoalwater Bay islands over the past 5000 years

Island archipelagos of the tropical coast of central Queensland include the most distant offshore islands used by Aboriginal Australians. Excavations on Collins, Otterbourne and High Peak Islands, located up to 40 km from the mainland, reveal evidence of offshore voyaging and marine specialisation in the Shoalwater Bay region for at least 5200 years. A time lag of up to 3000 years between island formation and systematic island use may reflect delayed development of key marine resources. Expansion of island use commencing around 3000–3500 years ago is linked to population increases sustained by synchronous increases in marine resources. Occupational hiatuses variously between 1000 and 3000 years ago are associated with increased ENSO activity. Intensified island use within the past 1000 years is primarily a social phenomenon associated with continuing demographic pressures and the development of more coastally and marine-focused mainland groups, with settlement patterns increasingly encompassing adjacent islands. The viability of risky offshore canoe voyaging was underwritten by two key high-return subsistence pursuits – hunting green turtles and collecting turtle eggs. In addition to subsistence and quartz quarrying, a key motivation for island visitation may have been socially restricted (e.g. ceremonial) practices.

Cost-effectiveness of reducing salt intake in the Pacific Islands: protocol for a before and after intervention study

Background
There is broad consensus that diets high in salt are bad for health and that reducing salt intake is a cost-effective strategy for preventing chronic diseases. The World Health Organization has been supporting the development of salt reduction strategies in the Pacific Islands where salt intakes are thought to be high. However, there are no accurate measures of salt intake in these countries. The aims of this project are to establish baseline levels of salt intake in two Pacific Island countries, implement multi-pronged, cross-sectoral salt reduction programs in both, and determine the effects and cost-effectiveness of the intervention strategies.

Methods/Design
Intervention effectiveness will be assessed from cross-sectional surveys before and after population-based salt reduction interventions in Fiji and Samoa. Baseline surveys began in July 2012 and follow-up surveys will be completed by July 2015 after a 2-year intervention period.

A three-stage stratified cluster random sampling strategy will be used for the population surveys, building on existing government surveys in each country. Data on salt intake, salt levels in foods and sources of dietary salt measured at baseline will be combined with an in-depth qualitative analysis of stakeholder views to develop and implement targeted interventions to reduce salt intake.

Discussion
Salt reduction is a global priority and all Member States of the World Health Organization have agreed on a target to reduce salt intake by 30% by 2025, as part of the global action plan to reduce the burden of non-communicable diseases. The study described by this protocol will be the first to provide a robust assessment of salt intake and the impact of salt reduction interventions in the Pacific Islands. As such, it will inform the development of strategies for other Pacific Island countries and comparable low and middle-income settings around the world.
