Contributions to the Cladocera fauna from Papua New Guinea

Twenty-eight taxa of the Cladocera are identified in collections from Papua New Guinea, 17 being new records for New Guinea, bringing the total number of Cladocera taxa reported for this region to 39. Most of the taxa are circumtropical. One species (Sarsilatona papuana) is endemic to Papua New Guinea and northern Australia. The species list includes two species that are normally listed as Holarctic:Alonella nana andAlona rustica. Widespread genera such asDaphnia, Pleuroxus, Disparalona, Acroperus were strikingly absent from the Papua New Guinean material.     

Introduction: The Politics of Order in Contemporary Papua New Guinea

ABSTRACT

This collection of articles seeks to demonstrate that the concept of order – the intensive and extensive coordination of human action across space and time – is useful for answering some of the most pressing theoretical and practical questions in contemporary Papua New Guinea (PNG) today. Building on existing work in this field [Benda-Beckmann, K., and F. Pirie. 2007. “Introduction.” In Order and Disorder: Anthropological Perspectives, 1–15. New York: Berghahn Books] in this special issue we ask: How do people create enduring, stable, and routinised life in contemporary Melanesia today? We position our work as the next step in a growing movement to study contemporary institutions in PNG as order-making projects, rather than attempting to divide them into legitimate projects like ‘government’ and false or ineffective ones like ‘cargo cults’.     

Studies of endemic cretinism in Papua New Guinea: digital and palmar dermatoglyphic patterns

We have tested the hypothesis that the abnormal development of the central nervous system seen in endemic cretinism might be accompanied by concurrent abnormal dermatoglyphic patterns. We compared digital and palmar dermatoglyphics of normal individuals and endemic cretins inhabiting the Huon Peninsula of Papua New Guinea. The population sampled from the Irumu River Valley included 118 males and 114 females with 22 male cretins and 23 female cretins. The population sampled from the Wantoat River Valley included 72 males and 38 females with 12 male cretins. No pathognomonic patterns were found that could identify the endemic cretin subpopulation. However, the occurrence of a number of differences between controls and cretins suggests that subtle changes in dermatoglyphic patterns accompany the anomalous development of the CNS secondary to maternal iodine deficiency. We discuss the significance of these findings and compare the dermatoglyphic patterns of normal Irumu and Wantoat natives and 21 other populations of Papua New Guinea.     

Colonial and postcolonial museum collecting in Papua New Guinea

This essay contrasts early and later colonial collecting by anthropologists and museum scientists in Melanesia with the postcolonial collecting in which I participated in the 1980s under the auspices of the Australian Museum (1987). My contention is that museum collections made during early colonialism took place in a relatively hierarchical and androcentric context of moral difference. In subsequent phases of the colonial era, as well as in the ongoing postcolonial period, anthropological collecting sought, and continues to seek, egalitarian and gender inclusive dialogue with vendors; in part by drawing from local metaphors and idioms to express status inclusivity.     

The seasonal factors influencing child malnutrition on the Nembi Plateau,Papua New Guinea

A sample of children from the Nembi Plateau, Papua New Guinea, is monitored for nutritional status, episodes of sickness and disease, diets, work activity of mothers, and weight changes; and health and census records are examined for seasonal patterns of disease, deaths, birth, and birth weights. A seasonal pattern in birth weight reinforced by a seasonal pattern in growth performance and compounded by a seasonal pattern of disease suggests that the time of year in which a child is born is important to the child's growth and health. Yields, labor, and ritual surrounding the gardens give rise to the seasonal pattern of events that impinge upon the health of children.     

Life Without Pigs: Recent Subsistence Changes Among the Irakia Awa, Papua New Guinea

Beginning in the late 1980s, the Irakia Awa commenced changing their basic subsistence adaptation. This included altering gardening practices, changing basic food consumption patterns, and most importantly, eliminating the production of domestic pigs. These changes were undertaken as part of an effort to improve the life experience of local residents and usher in a new plan of village improvement. The plan promoted the disintensification of subsistence production and increased involvement in cash-earning and recreational pursuits, as well as Christianity. If successful, the promoters of the plan hope that the village will become a more attractive place to live, migrants living away will return home to help revitalize the community, and Irakia will flourish in the new cash-oriented modern economy.

Male social status and its predictors among Garisakang forager-horticulturalists of lowland Papua New Guinea

Social hierarchy exists in all human societies, yet the characteristics important for achieving high social status may differ cross-culturally. Studies among Western industrialized populations often use indices of socioeconomic status (SES) to determine individual social position. Conversely, studies among small-scale societies typically use locally relevant traits. Cross-cultural applicability and the relationships between these two strategies have rarely been investigated. Studies limited to industrialized societies demonstrate that low social status is associated with poor health and elevated levels of chronic stress. It remains unclear, however, if and to what extent this relationship is a recent phenomenon in industrialized Western society or a universal human characteristic that has likely been present throughout much of our recent evolutionary history. In this study, we investigate relationships between various SES and locally relevant measures of male social status, age, body-mass index (BMI), and levels of waking salivary cortisol among relatively egalitarian Garisakang forager-horticulturalists of lowland Papua New Guinea. We employ a photo-ranking method using 32 raters (16 women, 16 men) to evaluate 15 measures of social hierarchy in men (N = 32). These measures target locally relevant traits considered important for male social status (e.g., sociability, hunting skills, fighting ability, and community influence). Using principal component analysis (PCA), we extracted two components labeled as Dominance-Respect and Prosociality-Skills. Models investigating predictors of social status demonstrate that age was significantly and positively related to both Dominance-Respect and Prosociality-Skills while BMI was positively related to only Dominance-Respect. Neither Dominance-Respect nor Prosociality-Skills predicted salivary cortisol levels. However, the SES measure of Income was significantly and positively related to cortisol levels, suggesting that men with higher income experience higher levels of stress. This finding may be explained by increased psychological stress accompanying market integration among the Garisakang or, alternatively, by culturally specific expectations for resource sharing and fear of conflict. These findings emphasize the usefulness of diverse social status measures in anthropological research and stress the need for broadened perspectives regarding the causes and consequences of social status among small-scale populations.     

Caprellids (Crustacea: Amphipoda) from Papua New Guinea,with the description of a new species

This is the first study of caprellid amphipods from the coast of Papua New Guinea. Several collections from Madang Lagoon (north) and Bootless Bay (south) have been studied. Seven species in seven genera are recorded, of which Pseudoproto papua sp. nov. is described as new to science. The genus Pseudoproto Mayer, 1903 has consisted, so far, of only one species, Pseudoproto fallax Mayer, 1903. Although only a single male has been found of Pseudoproto papua sp. nov., differences in antennae, mouthparts, gnathopod 2 and pereopods 3 and 4 have revealed that it represents a new species of Pseudoproto. Lateral view figures of all species, together with a key to species level for the Caprellidea from Papua New Guinea are also included. Communicated by H.-D. Franke     

Malaria vectors of Papua New Guinea

Understanding malaria transmission in Papua New Guinea (PNG) requires exact knowledge of which Anopheles species are transmitting malaria and is complicated by the cryptic species status of many of these mosquitoes. To identify the malaria vectors in PNG we studied Anopheles specimens from 232 collection localities around human habitation throughout PNG (using CO₂ baited light traps and human bait collections). A total of 22,970 mosquitoes were individually assessed using a Plasmodium sporozoite enzyme-linked immunosorbent assay to identify Plasmodiumfalciparum, Plasmodiumvivax and Plasmodiummalariae circumsporozoite proteins. All mosquitoes were identified to species by morphology and/or PCR. Based on distribution, abundance and their ability to develop sporozoites, we identified five species as major vectors of malaria in PNG. These included: Anophelesfarauti, Anopheleshinesorum (incriminated here, to our knowledge, for the first time), Anophelesfarauti 4, Anopheleskoliensis and Anophelespunctulatus. Anopheleslongirostris and Anophelesbancroftii were also incriminated in this study. Surprisingly, An. longirostris showed a high incidence of infections in some areas. A newly identified taxon within the Punctulatus Group, tentatively called An. farauti 8, was also found positive for circumsporozoite protein. These latter three species, together with Anopheleskarwari and Anophelessubpictus, incriminated in other studies, appear to be only minor vectors, while Anophelesfarauti 6 appears to be the major vector in the highland river valleys (>1500 m above sea level). The nine remaining Anopheles species found in PNG have been little studied and their bionomics are unknown; most appear to be uncommon with limited distribution and their possible role in malaria transmission has yet to be determined.     

Parabrosmolus novaeguineae,a new genus and species of the subfamily Brosmophycinae from Papua New Guinea (Bythitidae,Ophidiiformes)

Parabrosmolus novaeguineae, a new genus and species of the subfamily Brosmophycinae (family Bythitidae) is described, based on a single specimen from Papua New Guinea. The genus is unique in the tribe Brosmophycini in having six branchiostegal rays and ten precaudal vertebrae, and is also similarly distinguished from two brosmophycine genera,Melodichthys andBeaglichthys, tribal allocations of the two latter being uncertain.Parabrosmolus also differs from all other genera in the subfamily by the following combination of characters: head scaly, anal fin origin slightly before midpoint of body, eye diameter shorter than snout length, three developed rakers on first gill arch and 16 (14+2) caudal fin rays.     

Land tenure and transfer in Chimbu,Papua New Guinea: 1958–1984—A study in continuity and change,accommodation and opportunism

A long-term study of land tenure, land transfer, and succession in one subclan of the Chimbu in the Papua New Guinea highlands takes up the relations between the agricultural cycle, family, and population growth in a period of rapid commercialization and cash cropping. Over a generation, land was held and allocated within families, among families within the subclan, and to kin and affines in neighboring groups. The land tenure, ownership, and use system allows for a very great deal of individual movement and land gifts, temporary or long-term, by land owner to kin and friends. Despite an agnatic ideology, individuals and local groups opportunistically accommodate to land needs. As cultivation becomes more intensive and semi-permanent, there appears to be a progression from fluidity of land rights in the clan or subclan to anchoring of rights and boundaries to individuals and families. It is suggested that this characterizes Chimbu land tenure; it is not a postcolonial phenomenon.     

Ecological factors in skin color variation among Papua New Guineans

An EEL reflectance spectrophotometer was used to measure the skin color of the inner upper arm and the forearm of 913 Karkar Islanders (Madang District) and 684 Lufa villagers (Eastern Highlands District). The samples were subdivided to study sex, age, and population variation against a background of ecological observations, including sunlight exposure, clothing, and erythemally effective wavelengths of ultraviolet light (Robertson, unpublished Ph.D. thesis, 1974). Population differences in sex and age variation in upper arm skin color may largely be attributable to the effects of culturally associated clothing differences. Not only do the Lufa villagers wear substantially less clothing than the Karkars, but also their arms are exposed more frequently to ultraviolet light during heavy manual work in unshaded gardens. For the melanin content of the forearm skin there are similar patterns of age variation in both populations; however, the populations differ in mean percentage of reflectance throughout most of the age span. These between-population differences are interpreted as a consequence of greater average daily exposure to sunlight and the higher intensity of ultraviolet light in the highland environment. On the forearm the percentage of reflectance at 685 nm decreases more rapidly with age in the prepubertal and adult age groups, a result attributed to endocrine changes superimposed on cumulative changes in the melanin pigmentary mechanism.     

Bloody time revisited: New observations on time in a Papua New Guinea Village

In a 1982 paper I argued that perceptions of time scarcity in Kragur Village, Papua New Guinea, in the mid‐1970s were best understood as a reaction to new forms of authority characteristic of the growth of capitalism and calls for greater time order were grounded largely in its perceived ritual significance. More than forty years later, villagers are much more familiar with Western time, but less likely to perceive time as scarce. As in the 1970s, aspiring leaders still press for greater time order. Millenarian illusions informed advocacy of time order in the 1970s. Although today these illusions are, if not extinct, then dormant, unquestioned assumptions mirroring Western capitalist views of time inspire many of today's advocates. Yet, lacking the authority to impose new forms of time order, they have little effect on the rhythms of village life, and economic incentives to abandon comparative indifference to time remain weak.     

Emplacement and resistance: Social and political complexities in development‐induced displacement in Papua New Guinea

This paper argues that attending to social and political factors in development‐induced displacement is critical even for projects that involve resettlement of small populations. Taking the resettlement of two villages by the Lihir Gold Mine in Papua New Guinea as a unique case study, I analyse why one village was relatively successfully resettled, while the other has been very complicated, leading to hostility and conflict. In these cases the initial focus of all concerned in reaching a resettlement agreement was on the adequacy of compensation and housing, which mimicked the focus in the literature during the 1990s on impoverishment and compensation. From the late 1990s there have been calls for greater attention to social and political aspects of displacement and resettlement. Early attention to these factors in the Lihir case, particularly the key concepts of emplacement and disemplacement, would have highlighted flaws in the resettlement agreement and would have made it easier to avert the conflict and resistance that arose.     

A bioregional analysis of the distribution of rainforest cover,deforestation and degradation in Papua New Guinea

Papua New Guinea (PNG) is an extensively forested country. Recent research suggests that despite commencing a trajectory of deforestation and degradation later than many counties in the Asia–Pacific region, PNG is now undergoing comparable rates of forest change. Here we explore the bioregional distribution of changes in the forest estate over the period 1972–2002 and examine their implications for forest protection. This is undertaken through the development of a novel bioregional classification of the country based on biogeographic regions and climatic zones, and its application to existing forest cover and forest‐cover change data. We found that degradation and deforestation varied considerably across the 11 defined biogeographic regions. We report that the majority of deforestation and degradation has occurred within all the lowland forests, and that it is these forests that have the greatest potential for further losses in the near term. The largest percentage of total change occurred in the east of PNG, in the islands and lowlands of the Bismarck, D'Entrecasteaux, East Papuan Islands and in the South‐East Papua–Oro region. The only region with a significant highlands component to undergo deforestation at a comparable magnitude to the islands and lowland regions was the Huon Peninsula and Adelbert region. Significant changes have also occurred at higher elevations, especially at the interface of subalpine grasslands and upper montane forests. Lower montane forests have experienced proportionally less change, yet it is these forests that constitute the majority of forests enclosed within the protected area system. We find that protected areas are not convincingly protecting either representative areas of PNG's ecosystems, nor the forests within their borders. We conclude by suggesting a more expansive and integrated approach to managing the national forest estate.     

Crowds,Affect, and the Mediation of Emergent Collectivities: A Student Strike in Papua New Guinea as an Order-Making Project

ABSTRACT

From the institutional perspective of a university, student strikes mark a time of heightened disorder. In this contribution, I turn this perspective around and analyse a student strike at the University of Goroka in the Papua New Guinea highlands as an order-making project instead. The observed student strike established an alternative regime among students, which was reinforced through a sense of having achieved a superior sophistication of order through the effective, and affective, alignment of minds and bodies into a single entity. Placing the achievement of collective unity in relation to what appears as Melanesian notions of order on one hand, and recent re-evaluations of the psychology of crowds within anthropology and sociology on the other hand, I explore conceptual connections in the work of ‘mediation’ between order making in Melanesia and contemporary (critiques of) affect theory.     

Resource conflicts and the anthropology of the dark and the good in highlands Papua New Guinea

In this article I consider why individuals sacrifice their lives for the collective. In the Porgera Valley of highlands Papua New Guinea, young men who are called ‘Rambos’ engage in sustained tribal conflicts due to increasing social inequalities in an area that is supposedly benefiting from socioeconomic development. The opening of the Porgera Gold Mine in 1990 ushered in an era of anticipated benefits that were hoped to transform the lives of the region's subsistence horticulturalists. Yet, anticipated flows of mining money and social benefits have largely failed to materialise. The abjection experienced by young men eventuated into a series of tribal fights, resulting in deaths, displacements, and the destruction of most infrastructure. I examine the fighting and its aftermath in relation to anthropologies of the dark and the good and argue that these polar opposites can hinder more subtle understandings of value plurality among Porgerans.     

Forest Conversion and Degradation in Papua New Guinea 1972–2002

Quantifying forest change in the tropics is important because of the role these forests play in the conservation of biodiversity and the global carbon cycle. One of the world's largest remaining areas of tropical forest is located in Papua New Guinea. Here we show that change in its extent and condition has occurred to a greater extent than previously recorded. We assessed deforestation and forest degradation in Papua New Guinea by comparing a land-cover map from 1972 with a land-cover map created from nationwide high-resolution satellite imagery recorded since 2002. In 2002 there were 28,251,967 ha of tropical rain forest. Between 1972 and 2002, a net 15 percent of Papua New Guinea's tropical forests were cleared and 8.8 percent were degraded through logging. The drivers of forest change have been concentrated within the accessible forest estate where a net 36 percent were degraded or deforested through both forestry and nonforestry processes. Since 1972, 13 percent of upper montane forests have also been lost. We estimate that over the period 1990–2002, overall rates of change generally increased and varied between 0.8 and 1.8 percent/yr, while rates in commercially accessible forest have been far higher—having varied between 1.1 and 3.4 percent/yr. These rates are far higher than those reported by the FAO over the same period. We conclude that rapid and substantial forest change has occurred in Papua New Guinea, with the major drivers being logging in the lowland forests and subsistence agriculture throughout the country with comparatively minor contributions from forest fires, plantation establishment, and mining.
