The diversity of angiosperms in primitive families, which occur in the Wet Tropics of Queensland, is frequently cited as evidence of the ancient nature of the Australian rain forests, but appears to be based on flawed taxonomic assumptions. We point out the error of identifying species as being primitive rather than representing families with ancient origins, list the families from near-basal lineages using a current molecular phylogeny, and compare their diversity with other areas of rain forest in Australia, and with other tropical areas in the Pacific. Twenty-eight dicot families below the eudicot clade may be regarded as near-basal; 16 of these are present in rain forest habitat in the Wet Tropics. The diversity of near-basal families, and of the species and endemics within these families, is similar in New Caledonia, and the family diversity similar to Costa Rica. We suggest that these data are consistent with other evidence that rain forest has persisted on the Australian continent for a long time, and that the role of Australian rain forests in harbouring a significant near-basal component has been underestimated. We also suggest that ongoing management might be focussed at conserving the evolutionary history present in the near-basal lineages, especially in the face of changing climatic patterns.

This book provides a survey of different ways in which economic sociocultural and political aspects of human progress have been studied since the time of Adam Smith. Inevitably, over such a long time span, it has been necessary to concentrate on highlighting the most significant contributions, rather than attempting an exhaustive treatment. The aim has been to bring into focus an outline of the main long-term changes in the way that socioeconomic development has been envisaged. The argument presented is that the idea of socioeconomic development emerged with the creation of grand evolutionary sequences of social progress that were the products of Enlightenment and mid-Victorian thinkers. By the middle of the twentieth century, when interest in the accelerating development gave the topic a new impetus, its scope narrowed to a set of economically based strategies. After 1960, however, faith in such strategies began to wane, in the face of indifferent results and general faltering of confidence in economists’ boasts of scientific expertise. In the twenty-first century, development research is being pursued using a research method that generates disconnected results. As a result, it seems unlikely that any grand narrative will be created in the future and that neo-liberalism will be the last of this particular kind of socioeconomic theory.

Abstract:The decomposition of leaf litter is governed, in part, by litter invertebrates. In tropical rain forests, ants are dominant predators in the leaf litter and may alter litter decomposition through the action of a top-down control of food web structure. The role of ants in litter decomposition was investigated in a Costa Rican lowland rain forest with two experiments. In a mesocosm experiment, we manipulated ant presence in 50 ambient leaf-litter mesocosms. In a litterbag gradient experiment, Cecropia obtusifolia litter was used to measure decomposition rate constants across gradients in nutrients, ant density and richness, with 27 separate litterbag treatments for total arthropod exclusion or partial arthropod exclusion. After 2 mo, mass loss in mesocosms containing ants was 30.9%, significantly greater than the 23.5% mass loss in mesocosms without ants. In the litter bags with all arthropods excluded, decomposition was best accounted by the carbon: phosphorus content of soil (r2 = 0.41). In litter bags permitting smaller arthropods but excluding ants, decomposition was best explained by the local biomass of ants in the vicinity of the litter bags (r2 = 0.50). Once the microarthropod prey of ants are permitted to enter litterbags, the biomass of ants near the litterbags overtakes soil chemistry as the regulator of decomposition. In concert, these results support a working hypothesis that litter-dwelling ants are responsible for accelerating litter decomposition in lowland tropical rain forests.

A reporting field trip by Australian journalism students to New Caledonia and Vanuatu in mid-2014 produced markedly differing impressions of the neighbouring island societies, linked to their ‘independence’ status—one as an integrated territory of France, the other as an independent state. The field trip, one of a series from the Queensland University of Technology, aimed at developing reporting skills through work in unaccustomed territory, especially different cultural settings. Over 17 days, six students and the coordinator, and author of this article, generated 18 feature-length reports for online outlets and a radio documentary. The article synthesises the collected work from the field, producing a thematic statement of findings. It records broad consensus in New Caledonia in favour of enacting the Matignon and Noumea Accords on independence, while noting an undercurrent of unresolved conflicts. It characterises public life in Vanuatu in terms of a democratic spirit, and the invocation of traditional ties within society, as the country grapples with problems of development and impacts of the outside world. This work is interpretative, concerned with identifying processes underlying events in daily news. It is proposed as a first step towards a scholarly construction of meta-analyses of the interpretative and informative power of journalistic reporting.

Incursions of the Coconut rhinoceros beetle (CRB), Oryctes rhinoceros, have been detected in several countries of the south-west Pacific in recent years, resulting in an expansion of the pest's geographic range. It has been suggested that this resurgence is related to an O. rhinoceros mitochondrial lineage (previously referred to as the CRB-G biotype) that is reported to show reduced susceptibility to the well-established classical biocontrol agent, Oryctes rhinoceros nudivirus (OrNV). We investigated O. rhinoceros population genetics and the OrNV status of adult specimens collected in the Philippines and seven different South Pacific island countries (Fiji, New Caledonia, Papua New Guinea (PNG), Samoa, Solomon Islands, Tonga, and Vanuatu). Based on the presence of single nucleotide polymorphisms (snps) in the mitochondrial Cytochrome C Oxidase subunit I (CoxI) gene, we found three major mitochondrial lineages (CRB-G, a PNG lineage (CRB-PNG) and the South Pacific lineage (CRB-S)) across the region. Haplotype diversity varied considerably between and within countries. The O. rhinoceros population in most countries was monotypic and all individuals tested belonged to a single mitochondrial lineage (Fiji, CRB-S; Tonga, CRB-S; Vanuatu, CRB-PNG; PNG (Kimbe), CRB-PNG; New Caledonia CRB-G; Philippines, CRB-G). However, in Samoa we detected CRB-S and CRB-PNG and in Solomon Islands we detected all three haplotype groups. Genotyping-by-Sequencing (GBS) methods were used to genotype 10,000 snps from 230 insects across the Pacific and showed genetic differentiation in the O. rhinoceros nuclear genome among different geographical populations. The GBS data also provided evidence for gene flow and admixture between different haplotypes in Solomon Islands. Therefore, contrary to earlier reports, CRB-G is not solely responsible for damage to the coconut palms reported since the pest was first recorded in Solomon Islands in 2015. We also PCR-screened a fragment of OrNV from 260 insects and detected an extremely high prevalence of viral infection in all three haplotypes in the region. We conclude that the haplotype groups CRB-G, CRB-S, and PNG, do not represent biotypes, subspecies, or cryptic species, but simply represent different invasions of O. rhinoceros across the Pacific. This has important implications for management, especially biological control, of Coconut rhinoceros beetle in the region.

We have not yet emerged into a post-COVID world. The future is fluid and unknown. As the Academy morphs under pressure, as design practitioners and educators attempt to respond to the shifting world – in the M?ori language, Te Ao Hurihuri – how might we manage such changes? There is an indigenous precedent of drawing upon the past to assist with present and future states – as the proverb ka mua ka muri indicates, ‘travelling backwards into the future,’ viewing the past spread out behind us, as we move into the unknown. Indigenous academics often draw inspiration from extant traditional viewpoints, reframing them as methodologies, and drawing on metaphor to shape solutions. Some of these frameworks, such as Te Whare Tapa Wh?, developed as a health-based model, have been adapted for educational purposes. Many examples of metaphor drawn from indigenous ways of thinking have also been adapted as design or designrelated methodologies. What is it about the power of metaphor, particularly indigenous ways of seeing, that might offer solutions for both student and teacher? One developing propositional model uses the Pacific voyager as exemplar for the student. Hohl cites Polynesian navigation an inspirational metaphor, where “navigating the vast Pacific Ocean without instruments, only using the sun, moon, stars, swells, clouds and birds as orienting cues to travel vast distances between Polynesian islands.”1 However, in these uncertain times, it becomes just as relevant for the academic staff member. As Reilly notes, using this analogy to situate two cultures working as one: “like two canoes, lashed together to achieve greater stability in the open seas … we must work together to ensure our ship keeps pointing towards calmer waters and to a future that benefits subsequent generations.”2 The goal in formulating this framework has been to extract guiding principles and construct a useful, applicable structure by drawing from research on twoexisting models based in Samoan and Hawaiian worldviews, synthesised via related M?ori concepts. Just as we expect our students to stretch their imaginations and challenge themselves, we the educators might also find courage in the face of the unknown,drawing strength from indigenous storytelling. Hohl describes the advantages of examining this approach: “People living on islands are highly aware of the limitedness of their resources, the precarious balance of their natural environment and the long wearing negative effects of unsustainable actions … from experience and observing the consequences of actions in a limited and confined environment necessarily lead to a sustainable culture in order for such a society to survive.”3 Calculated risks must be undertaken to navigate this space, as shown in this waka-navigator framework, adapted for potential use in a collaborative, studio-style classroom model. 1 Michael Hohl, “Living in Cybernetics: Polynesian Voyaging and Ecological Literacy as Models fordesign education, Kybernetes 44, 8/9 (October 2015). https://doi.org/ 10.1108/K-11-2014-0236.2 Michael P.J Reilly, “A Stranger to the Islands: Voice, Place and the Self in Indigenous Studies”(Inaugural Professorial Lecture, University of Otago, Dunedin, New Zealand, 2009).http://hdl.handle.net/10523/51833 Hohl, “Living in Cybernetics”.

The recent recognition of numerous small geological terranes in the Indo-Pacific region has revolutionised our understanding of geological and biogeographic processes. Most of these terranes rifted from Gondwana. The Shan-Thai terrane rifted from Australia in the Permian and collided with Indo-China in the Triassic. Parts of Sumatra and Kalimantan may have rifted from Australia in the Cretaceous and carried an angiosperm flora north. Other terranes, now dispersed in South-East Asia and in the Pacific were, at various times in the Cenozoic, part of the Australian continent. Faunal and floral mobilism to Fiji via the Solomons and Vanuatu was probably not difficult up to the late Miocene.

Abstract:The upper canopy of some rain forests in New Caledonia is dominated by single species. These monodominants are commonly secondary species, their dominance not persisting without disturbance. We tested whether dominance is associated with efficient uptake and use of nutrients (N, P and K), comparing between seedlings of monodominants (Nothofagus spp., Arillastrum gummiferum and Cerberiopsis candelabra) and 14 subordinates, grown in a nursery house. We also tested whether this trend applies more broadly to shade-intolerant trees that regenerate episodically (ER species) versus shade-tolerant trees that regenerate continuously (CR species). In the sun treatment, monodominants had higher photosynthetic nutrient-use efficiency and productivity for N and K, and uptake efficiency for N, P and K, than subordinates; ER species had higher photosynthetic nutrient-use efficiency for N, P and K, and uptake efficiency for N and P, than CR species. Uptake efficiency and productivity per nutrient mass were uncorrelated across species, yet Nothofagus spp., A. gummiferum and C. candelabra combined high levels of both traits for N, and Nothofagus spp. and A. gummiferum combined moderate to high levels for P, in sun-grown seedlings. This trait combination may contribute substantially to competitiveness and post-disturbance dominance on these nutrient-poor soils.

Based on the results of research on the vegetation around Padang Lawas Temples, Padang Lawas Regency, North Sumatera Province, can be known that Padang Lawas Temple sites are located in vegetation environment of lowland tropical rain forest with a high level diversity of plant families, one of those plant families is Euphorbiaceae with one of its species, Phylanthus emlica. L(Balaka). Phylanthus emlica is a type wild plant that grows open spaces in lowland tropical rain forests. Observing its life characteristic and its habitat, then Balaka plant (Phylanthus emlica) in Padang Lawas Temples’ yards was not planted in purpose planted but grows naturally. Balaka plant (Phylanthus emlica) has different name in every area. In Melayu, this plant is known as malaka. In Minangkabau known as balaka, in Sunda known as malaka and in Java, this plant is known as Kemloko, meanwhile in Madura and Bali this plant is called mlakah ,and karsinta in Flores (NTT)

The bagne retains an ambiguous status as a lieu de mémoire, in part because of its predominantly extra-metropolitan location, in part because most understandings of the institution rely heavily on representations freighted via literature, film and graphic fiction. In French Guiana and New Caledonia, the bagne was nevertheless the major driver in the attempted mise en valeur of those colonies in the face of varying degrees of resistance to settlement. Moreover, France’s carceral archipelago extended beyond those key sites to include penal colonies in North and Sub-Saharan Africa as well as Indochina. The essay scrutinizes the rich body of material that has served as a vehicle for memories of the institution, but uses a focus on contemporary memorial practices in French Guiana and New Caledonia to suggest a distinct divergence in forms of interpretation, especially regarding the place of the penal colony in colonial expansionism. Although until recent years the bagne has often acted as more of a postcolonial lieu d’oubli, in a context of complex postcolonial politics and of growing interest in penal heritage its status as a lieu de mémoire is becoming increasingly apparent.
