Keratinolytic and keratinophilic fungi in the soils of Papua New Guinea

A study was made of soil samples collected during an expedition to the Highlands of Papua New Guinea. Fungi were isolated from the samples by the method of hair baiting (To-Ka-Va). Of the 33 species isolated, about half showed keratinolytic activity. Such activity is previously unreported for Mucor hiemalis f. hiemalis, Myrothecium roridum, Paecilomyces carneus, P. marquandii, Penicillium brevicompactum, Rhinocladiella mansonii and Verticillium lecanii. The species most active keratinolytically were Chrysosporium an. Arthroderma cuniculi, C. an. A. curreyi, C. indicum, Myceliophthora vellerea and Trichophyton ajelloi. The spectrum of fungi with keratinolytic activity isolated from the different sites differed considerably according to the frequency of use by man, heaviest use being correlated with greatest activity. The pH of the soil (varying from 5.8–7.5) had little influence on the type of such fungi isolated.     

Litter production and seasonality of mangroves in Papua New Guinea

Productivity, as measured by litter trapping, of a mangrove dominated by Rhizophora stylosa Griff. at Motupore Island (lat. 9° 31′34′?S; long. 147° 17$\text{\$}\text{?}$02‘ E) was 1430 g dry weight m^?2 year^?1. This is a high figure when compared with other studied mangrove sites. Phenological data were obtained for R. stylosa, R. apiculata Blume and Sonneratia alba Smith. All species have a major leaf fall in the wet season. Flowering in both Rhizophora species is greatest during the wet season, but S. alba peaks during the dry season. Leaf emergence data were only available for R. stylosa and these appeared to be trimodal. Correlations were calculated for each component with rainfall, wind run, maximum temperature and minimum temperature. Some significant correlations were obtained with rainfall and maximum temperature. These correlations are discussed and it is suggested that the seasonality of mangrove phenologies needs to be considered in terms of whole tree physiology rather than isolated environmental factors.     

Education and the "new" inequality in Papua New Guinea

Literature has been produced over the last fifteen years in Papua New Guinea (PNG) concerned with the increasing level of socioeconomic differentiation which has accompanied political independence. Consensus exists that postcolonial PNG is experiencing increasing disparities in education, wealth, political power, and the general set of benefits typically associated with development and modernization. This author argues that studies of such growing socioeconomic stratification in the country have ignored or dismissed gender as a source of inequality. She focuses upon educational opportunity as the key to wealth and political power and shows that the most educationally disadvantaged group in PNG is rural women. Data to support her thesis are drawn from national censuses, the author's field work in the area of Madang Province, and literature on stratification. The national census includes data from both lowland and highland populations. Since the authors' field site is culturally and ecologically highland, however, the paper focuses upon the highlands, using data from nonhighland areas primarily for comparative purposes.     

Genetic distance: probing the origin of a Papua New Guinea isolate

In an attempt to elucidate the origin of an isolated peripheral Highland, Papua New Guinea population (the Karimui), HLA, blood group and serum protein markers were investigated. Due to the paucity of published HLA marker data, genetic distances using non-HLA markers were constructed between populations surrounding the Karimui and compared in 3-dimensions by multidimensional scaling analysis. Genetically, the Karimui is most closely associated with Highland populations to the east and northeast. In a attempt to develop a more global view of relationships, distances constructed from HLA marker data between 2 close Highland populations, 2 Coastal Papua New Guinea populations and 4 Australian aborigine populations were compared. The Karimui associated most closely with the Highland populations and equidistantly and at opposite poles from both the Coastal Papuan and aborigine populations. A paradigm of the composition of the founder group and the early population dynamics is developed from genetic, linguistic and anthropologic data.     

Conceiving relatedness: non-substantial relations among the Kamea of Papua New Guinea

This article considers the implications of imagining kinship as a non-embodied relation. In recent years, it has become commonplace to argue that relatedness is a gradually acquired state that can be built over time and by non-sexual means. In this view, relationships of consanguinity are not given at birth but are created through purposeful acts of feeding and caring. Here, I address a question that has been less commonly asked by anthropologists: need kinship always be imagined as entailing an embodied connection? Is there a way of thinking about cross-generational relationships that does not ground them in bodily connectedness, or, at the very least, one that imagines contexts in which they are not embodied as a substantial link between people? Drawing upon data collected among Kamea of Papua New Guinea, I describe a world in which the parent-child tie is conceptualized as one that is inherently non-embodied.     

Mobility,Violence and the Gendering of HIV in Papua New Guinea

The links between gender, sexuality and violence hold serious implications for HIV transmission and its social and economic effects. In Papua New Guinea, enduring and pervasive patterns of male sexual behaviour involving coercion, violence and gang rape are highly conducive to the transmission of HIV and other sexually transmitted infections and have a critical bearing on women's sexual autonomy and health. The realities of violence are intensified by the widespread view that women are responsible for the spread of the virus. This paper engages the theme of mobility to consider the fluid and dynamic character of gender relations and sexuality in contemporary Papua New Guinea, and to gain perspective on constructions of modern masculinity and the discursive representations of gender violence in the context of the escalating HIV epidemic.

Generic plant assemblages in the highland forests of Papua New Guinea

Virtually complete tree lists from seventy-eight sites in four regions above 1900 in a.s.l. in Papua New Guinea are analysed numerically and the results compared with classifications already in use. A major floristic break occurs between 2800 m and 3000 w a.s.l. The Upper Mountain Forest above this is tentatively divided into four nodes, the altitudinally lowest (< 3400 m) being pliysiognomically similar to the forest below. The Lower Mountain Forest below the major break has two nodes, one of which may be an assemblage of variously depauperate and less stable derivatives of the other: they are not altitudinally distinct.     

Many medicines in one: Curing in the Eastern Highlands of Papua New Guinea

The actual means by which the clinical successes of non-Western medical treatments are achieved has been little explored. More specifically, analyses have focused almost exclusively on their psychotherapeutic value, with some attention to the pharmacodynamics of plant remedies. The central argument of this paper is that such a perspective has been generated more by the selective psychiatric orientation of cross-cultural field workers than by the diverse realities of the curing systems themselves. The paper describes medical care among the Nekematigi, Benabena-speaking horticulturalists of the Eastern Highlands of Papua New Guinea. Presented within an ecological framework, these materials demonstrate dependence upon a wide range of physical manipulations such as bleeding and flagellation with nettles, dietary alterations including increased protein consumption, social rearrangements, verbal spells, and plant medicinals of both specific and general application. The potential effects of each contribution to the medical regime are examined and a twofold conclusion is reached: (1) that it is precisely the mix of physical and psychological elements that accounts for Nekematigi success in treating the chronic infectious diseases which predominate in their environment, and (2) that this is likely to be true of many previously reported medical systems hitherto interpreted primarily in psychological, social, or symbolic terms.

Contested Knowledge, Contingent Classification: Animals in the Highlands of Papua New Guinea

New Guinea highlanders appear to conceive of animal taxonomy in a way that is simultaneously familiar to a scientist, yet different. This is often attributed to interaction between natural ecology, which constrains content, and cultural context, which conditions the structure of any taxonomy. The evidence presented here confirms this view, although the considerable, and initially disconcerting, disagreements between persons over taxonomic issues raise the question: To what extent is Wola classification of natural phenomena analogous to Western hierarchical classification? The stateless political environment conditions the Wola constantly to challenge hierarchy, obfuscate boundaries, and think in terms of "fuzzy sets," confounding the assumption of agreed classes and threatening intellectual anarchy. However, their taxonomic regime offsets this, facilitating discourse in the absence of authorities to adjudicate in disputes. No formal classificatory scheme devised so far can adequately represent such an oral tradition's ever negotiated ordering of animals; whatever framework we adopt will somewhat distort it.
