An evaluation of the culture performance of two Macrobrachium species in Vanuatu: the exotic M. rosenbergii and the indigenous M. lar

Fisheries and aquaculture are important for food security, income generation and are critical to long term sustainability of many countries. Freshwater prawns have been harvested in the streams and creeks in Vanuatu, however due to over-exploitation catches have declined in recent years. To satisfy high demand for this product, Vanuatu government intends to establish economically viable small-scale aquaculture industries. The current project showed that wild Macrobrachium lar in Vanuatu constitute a single population for management purposes and that M. rosenbergii grows much faster than M. lar in simple pond grow-out systems, hence is a better species for culture in Vanuatu.

Social media and e-democracy in Fiji, Solomon Islands and Vanuatu

This paper examines the extent social media is enabling e-democracy in Fiji, Solomon Islands and Vanuatu. The study conducts an interpretative case study approach interviewing active social media users, political actors, civil servants, civilians, civil society actors and tertiary students. The study also conducts a content analysis of popular “political social media” Facebook pages in these three countries. The findings of the study suggest that social media is playing a role in facilitating citizen engagement with governments, making governments accountable and providing a means for citizens to be informed, to discuss and share views on political matters. However, social media usage is evolving quite differently in these three countries and factors such as high levels of militarism (Fiji), high levels of corruption (Solomon Islands) and also rapid ICT development (Vanuatu) have contributed towards shaping the potential of social media as a democratic enabler and political tool in these countries.

National Profiles of In-Country Capacity to Support Disability-Inclusive Education; Fiji, Samoa, Soloman Islands and Vanuatu

This publication emanates from the four-country research project entitled “Strengthening capacity for disability-inclusive education development policy formulation, implementation and monitoring in the South Pacific region” funded by the Australian Development Research Award Scheme (ADRAS) and conducted jointly by the academic staff from the Queensland University of Technology and the University of the South Pacific.

The influences of Bislama on lexical choices in children's written English: A case study in Vanuatu

In Vanuatu, there have been concerns that Bislama (the national language of Vanuatu and a creole with an adapted English vocabulary) hinders English language learning. Consequently, previous language policy restricted the use of Bislama in schools. The findings from this study offer significant insights and implications that may assist teachers with using Bislama in their classrooms in a way that furthers English language and literacy development. This research is timely because the Vanuatu Government have recently implemented a new language policy that allows the vernacular island languages and Bislama to be used as a linguistic resource in schools.

Oidiopsis (Erysiphaceae) on Euphorbia spp. in Australia and Vanuatu

One specimen of powdery mildew on Euphorbia cyathophora from Vanuatu and 11 specimens on E. cyathophora, E. dentata, E. heterophylla and E. leucocephala from Australia were studied. All were shown to represent the Oidiopsis anamorph of Leveillula taurica, which is described. This is the first record of Oidiopsis in Vanuatu. E. leucocephala is a new host record for this powdery mildew.

Geographic and Phenotypic Variation in Heartwood and Essential-Oil Characters in Natural Populations of Santalum austrocaledonicum in Vanuatu.

Phenotypic variation in heartwood and essential-oil characters of Santalum austrocaledonicum was assessed across eleven populations on seven islands of Vanuatu Trees differed significantly in their percentage heartwood cross-sectional area and this varied independently of stem diameter The concentrations of the four major essential-oil constituents (alpha-santalol, beta-santalol. (Z)-beta-curcumen-12-ol, and cis-nuciferol) of alcohol-extracted heartwood exhibited at least tenfold and continuous tree-to-tree variation Commercially important components alpha- and beta-santalol found in individual trees ranged from 0 8-47% and 0-24 1%, respectively, across all populations, and significant (P < 0 05) differences for each were found between Individual populations. The Erromango population was unique in that the mean concentrations of its monocyclic ((Z)-beta-curcumen-12-ol and cis-nuciferol) sesquiterpenes exceeded those of Its bi- and tricyclic (alpha- and beta-santalol) sesquiterpenes Heartwood colour varied between trees and spanned 65 colour categories, but no identifiable relationships were found between heartwood colour and alpha- and beta-santalol, although a weak relationship was evident between colour saturation and total oil concentration These results indicate that the heartwood colour is not a reliable predictive trait for oil quality The results of this study highlight the knowledge gaps in fundamental understanding of heartwood biology in Santalum genus The intraspecific variation in heartwood cross-sectional area. oil concentration. and oil quality traits is of considerable importance to the domestication of sandalwood and present opportunities for the development of highly superior S austrocaledonicum cultivars that conform to the industry's International Standards used for S album.

Vital statistics of marine fishes of Vanuatu

Vital statistics are presented for 38 marine species of Vanuatu based on previous studies conducted in the area, with parameters describing growth (6 species, 13 sets of parameters), mortality (estimates of M for 6 species), length-weight relationship (32 species), and reproduction (length at first maturity for 26 species, months of reproduction for 18 species). The species covered belong mainly to the family Lutjanidae.

Genetic and migratory evidence for sympatric spawning of tropical Pacific eels from Vanuatu

The spawning areas of tropical anguillid eels in the South Pacific are poorly known, and more information about their life histories is needed to facilitate conservation. We genetically characterized 83 out of 84 eels caught on Gaua Island (Vanuatu) and tagged 8 eels with pop-up satellite transmitters. Based on morphological evidence, 32 eels were identified as Anguilla marmorata, 45 as A. megastoma and 7 as A. obscura. Thirteen of these eels possessed a mitochondrial DNA sequence (control region, 527 bp) or nuclear haplotype (GTH2b, 268 bp) conflicting with their species designation. These individuals also had multi-locus genotypes (6 microsatellite loci) intermediate between the species, and 9 of these eels further possessed heterozygote genotypes at species-diagnostic nuclear single nucleotide polymorphisms (SNPs). We classified these individuals as possibly admixed between A. marmorata and A. megastoma. One A. marmorata and 1 A. megastoma migrated 634 and 874 km, respectively, towards the border between the South Equatorial Current and the South Equatorial Counter Current. Both species descended from around 200 m depth at night to 750 m during the day. Lunar cycle affected the upper limit of migration depths of both species. The tags remained attached for 3 and 5 mo and surfaced <300 km from the pop-up location of a previously tagged A. marmorata pop-up location. A salinity maximum at the pop-up locations corresponding to the upper nighttime eel migration depths may serve as a seamark of the spawning area. The similar pop-up locations of both species and the evidence for admixture suggest that these tropical eels share a sympatric spawning area.
