Three new Indo-Australian species of the sciaenid genusAtrobucca,with a reevaluation of generic limit

Three new species of the sciaenid genusAtrobucca are described:A. kyushini from off Borneo, differs from all known congeners in having no swimbladder appendages enveloplng the bladder, no forward directed branches from the ventral limbs of the appendages, a long tube-like last appendage parallel to the bladder wall and a pale mouth lining;A. brevis from off northern Australia and Papua New Guinea, is distinguished by its short pectoral fin (less than 23% SL) and pleural rib on the 11th vertebra;A. adusta from Papua New Guinea, is distinctive in having a low dorsal soft ray number (23–24) and long caudal peduncle (27–30% SL).Atrobucca Chu, Lo et Wu is redefined to accommodate the new species: the genus is principally characterized by the swimbladder appendages divided into developed dorsal and ventral limbs, and the only slightly curved sulcus tail of the sagitta. A key and diagnoses are provided for all known species ofAtrobucca.     

Etolo hunting performance and energetics

Analyses of nearly 3000 hr of hunting for mammals by Etolo people of Papua New Guinea reveal that older hunters were more successful than younger hunters, that increased success was due, in large part, to higher rates of capture for only two of 24 prey species, and that access to a good hunting dog accounted for the increase in rate of capture for one of these two species. A comparison of Gadio Enga and Rofaifo mammal hunting with that of Etolo reveals a marked decline in energy and protein yields with increase of altitude. This is attributed to altitudinal changes in the composition of the available fauna within Papua New Guinea and to reinforcing effects from increased human population density.     

Paraplagusia longirostris,a new flatfish (Cynoglossidae) from Australia and Papua New Guinea

A new species of tongue sole,Paraplagusia longirostris, is described from 59 specimens (83.0– 276.2 mm SL) collected off the northern coast of Australia and southern coast of Papua New Guinea.P. longirostris is easily distinguishable from otherParaplagusia by its long, obtusely pointed snout and its high counts for dorsal and anal fin rays, caudal vertebrae and mid-lateral line scales.     

New genera and species of Chrysobalanaceae from Malesia and Oceania

Two new genera of Chrysobalanaceae are described.Hunga distributed in New Caledonia, the Loyalty Islands and Papua and New Guinea, contains eight species, three new, and five formerly placed in the generaAngelesia, Licania andParinari.Kostermanthus is described to accommodate two species with united filaments formerly placed inParinari andAcioa. Both new genera are quite as distinct as others of the family and have been overlooked by undue emphasis placed on the single character of a bilocular ovary.Licania palawanensis Prance is also described; it is the second species of its genus from Malesia.     

Sodium-rich tree ash as a native salt source in lowland Papua

The Gidra-speaking Papuans of the Oriomo Plateau, lowland Papua New Guinea, consume ash of two tree species (Melaleuca sp. andAcacia mangium) as a native salt. The ashes contain 100–200 mg sodium/g ash, which is very much higher than the sodium levels in native plant ashes (except for the swamp herbEriocaulon australe) collected in other regions of the world.     

Ethnobotany of WopkaiminPandanus significant Papua New Guinea plant resource

Pandanus is well represented in Papua New Guinea with over 66 species growing from sea level to 3,000 m. The territory of the Wopkaimin, who live at the headwaters of the Ok Tedi in the Star and Hindenburg Mountains, is particularly rich in wild and domesticated species ofPandanus. Detailed analysis of the species in classification, ecology, subsistence, ritual and material culture not only establishesPandanus as a locally significant plant resource but also contributes to the comparative understanding of ethnobiological systems. A close correspondence with botanical taxa of generic and specific rank and an absence of the most inclusive taxon term for plant are 2 cross-culturally important findings substantiated in WopkaiminPandanus taxonomy.     

Melanotaenia iris,a new freshwater rainbowfish (Melanotaeniidae) from Papua New Guinea with notes on the fish fauna in Head Waters

A new melanotaeniid rainbowfish,Melanotaenia iris, is described from mountain tributaries of the Strickland River in west-central Papua New Guinea. It is most closely related toM. goldiei of southern New Guinea, but differs in colour pattern, a distinctive high number of scales on the suborbital-preopercle bones, and a greater number of soft dorsal fin rays. Notes are also included on the poorly developed fish fauna of head waters in the Fly-Strickland and Sepik river systems. Most streams thus far investigated have less than 4 species. The plotosid catfishTandanus equinus appears to be the most successful colonizer of fast-flowing highland streams in the Fly-Strickland system and is sometimes the only species present.     

Specificity among the Casuarinaceae in root nodulation byFrankia

Pure cultured isolates ofFrankia made from root nodules of plant species from among three genera of the host family Casuarinaceae were used in inoculation trials of seedlings grown in water culture. A large number of host species among the genera Allocasuarina, Casuarina and Gymnostoma from Australia, Papua New Guinea and other South Pacific Islands were tested. The most widely infectiveFrankia strains were CcI3 and AllI1; theFrankia strains with the narrowest host range within the Casuarinaceae were CcI2 and GpI1. Intrafamily cross-inoculations were uncommon. The most broadly receptive host species wasG. papuanum. For many species ofAllocasuarina tested, no infection by anyFrankia available for testing could be observed.     

Helminths of rodents and marsupials from Papua New Guinea,with the description of two new species,Echinostoma echymiperae n. sp. (Digenea: Echinostomatidae) and Vampirolepis peroryctis n. sp. (Cestoda: Hymenolepididae)

The following rodents and marsupials from the Western Highlands of Papua New Guinea have been examined for helminths: Anisomys imitator, Melomys spp., Pogonomelomys ruemmleri, Rattus spp., Echymipera kalubu and Peroryctes raffrayanus. Two new species and a number of new host records are reported. Echinostoma echymiperae n. sp., a digenean from the intestine of Echymipera kalubu, is characterised by the number of collar spines, the body armature and the shape and position of the gonads. Vampirolepis peroryctis n. sp., a cestode from the intestine of Peroryctes raffrayanus, is characterised by the length of the rostellar hooks, the shape of the ovary, the arrangement of the testes in a triangle and the extent of the cirrus-sac. Hymenolepis aklei, H. bradleyi, H. antechini, H. bettongiae, H. cercarteti, H. isoodontis and H. potoroi are transferred to Vampirolepis as new combinations. E. kalubu is a new host for Linstowia semoni and Pogonomelomys ruemmleri is a new host for Hymenolepis diminuta. V. peroryctis is the first platyhelminth to be reported from Peroryctes raffrayanus and Raillietina (Raillietina) sp. the second to be reported from the genus Melomys.     

Pandanus from Ok Tedi region,Papua New Guinea,collected by Debra Donoghue

In the course of ethnobotanical and ethnoarchaeological studies in the Ok Tedi region, Kiunga subprovince, Western Province, Papua New Guinea, Debra Donoghue collected several botanical specimens as vouchers for her studies into the prehistory of edible-nut pandans in the New Guinea Highlands and for David Hyndman’s study of the use and names of pandans in the region. These specimens were submitted to me through Dr. Hyndman for identification, and one set of duplicates has been deposited in the Lae Herbarium (PNG) and another in the University of Malaya Herbarium (KLU). Some of the collections are of considerable botanical interest, representing hitherto little-known species. One collection represents a new edible-nut species. The following list contains the botanical identifications, collection data, and some taxonomic comments. All the collections were made in June 1981. The Ok Tedi region is located around 5°12’S, 141°17’E.     

New guinea salt fern (Asplenium acrobryum complex): Identity,distribution, and chemical composition of its salt

Fronds of a fern of theAsplenium acrobryum complex were traditionally used as a source of salt in the inland areas of Papua New Guinea. All previously published reports of the use of fern salt in the botanical and ethnobotanical literature had erroneously identified the species involved asAsplenium nidus, one of the common bird’s-nest ferns. A chemical analysis of the salts contained in the ash of the salt fern as well as those species related toAsplenium nidus revealed that the bulk of the inorganic component was potassium, calcium and chloride. These results are comparable to those published for the salt-yielding grass,Coix gigantean. There is no obvious chemical reason why onlyAsplenium acrobryum should be used for salt production in preference toAsplenium nidus and related species. In view of the low levels of consumption of such salt it is unlikely that there will be any cases of potassium toxicity attributable to the use of these plants.     

Changing status of the parasites of potato tuber mothPhthorimaea operculella [Lepidoptera: Gelechiidae] in Australia

Three introduced parasites ofPhthorimaea operculella (Zeller) are now widespread, and a fourth established in a limited area, in Australia.Apanteles subandinus Blanchard, which occurs from Tasmania to Queensland, is the most effective species and the outstanding parasite in Victoria. The extent of parasitism and the status of the various parasites were monitored from the time of their release until 1971. In many areas whereCopidosoma koehleri Blanchard was the only parasite found in 1966, a substantial increase in parasitism was recorded in subsequent years, following the liberation of other species. In the 1969–70 season there was an explosive increase inOrgilus lepidus Muesebeck, which became the dominant species in some coastal areas of New South Wales, displacingA. subandinus. Its change of status to a dominant position was associated with a change of sex ratio from 1.6 ♀: 1♂ to 1.0 ♀: 1 ♂.     

Past hybridization between Quercus macrocarpa and Quercus gambelii

Introgression between two allopatric species,Quercus macrocarpa andQ. gambelii, has been observed in two separate locations: northeastern New Mexico and the Black Hills of western South Dakota and adjacent Wyoming. The probability that this introgression is the result of long-range pollination appears remote. Presumably these two species hybridized during a period of past sympatric association. Further indication of past sympatry in the Black Hills is the presence of a common species of obligate parasite, i.e., wasp(Cynips insulensis) onQ. gambelii in the Rocky Mountains and onQ. macrocarpa of the Black Hills. The hybrid oaks in New Mexico probably reflect a westward migration ofQ. macrocarpa during pluvial periods of the Pleistocene.Quercus gambelii most likely reached the Black Hills during the warmer postglacial hypsithermal era. The hybridization reported here may reflect secondary sympatry, i.e., sympatric occurrence after the species, or their ancestors, became geographically separated.     

KIR diversity in Māori and Polynesians: populations in which HLA-B is not a significant KIR ligand

HLA class I molecules and killer cell immunoglobulin-like receptors (KIR) form a diverse system of ligands and receptors that individualize human immune systems in ways that improve the survival of individuals and populations. Human settlement of Oceania by island-hopping East and Southeast Asian migrants started ~3,500 years ago. Subsequently, New Zealand was reached ~750 years ago by ancestral Māori. To examine how this history impacted KIR and HLA diversity, and their functional interaction, we defined at high resolution the allelic and haplotype diversity of the 13 expressed KIR genes in 49 Māori and 34 Polynesians. Eighty KIR variants, including four ‘new’ alleles, were defined, as were 35 centromeric and 22 telomeric KIR region haplotypes, which combine to give >50 full-length KIR haplotypes. Two new and divergent variant KIR form part of a telomeric KIR haplotype, which appears derived from Papua New Guinea and was probably obtained by the Asian migrants en route to Polynesia. Māori and Polynesian KIR are very similar, but differ significantly from African, European, Japanese, and Amerindian KIR. Māori and Polynesians have high KIR haplotype diversity with corresponding allotype diversity being maintained throughout the KIR locus. Within the population, each individual has a unique combination of HLA class I and KIR. Characterizing Māori and Polynesians is a paucity of HLA-B allotypes recognized by KIR. Compensating for this deficiency are high frequencies (>50 %) of HLA-A allotypes recognized by KIR. These HLA-A allotypes are ones that modern humans likely acquired from archaic humans at a much earlier time.

Nematode parasites from the skin of the platypus Ornithorhynchus anatinus (Monotremata)

The morphology of three nematode taxa found in the skin of the platypus Ornithorhynchus anatinus (Monotremata) in southeastern New South Wales, Australia, is described and illustrated. Fourth-stage larvae belonging to the Rhabditoidea, ?Cylindrocorporidae, occurred primarily in superficial keratin and epidermal layers of the skin and in hair follicles. A nematode recognised by its conspicuous synlophe as a fourth-stage larva of the Trichostrongyloidea, of unknown genus and species but probably belonging to the molineid evolutionary line, was observed in histological section in the hypodermis. A gravid female nematode belonging to the Filarioidea, ?Lemdaninae, occurred in a lymphoid nodule in the hypodermis. O. anatinus is a protected species and these data are presented to draw the attention of parasitologists to skin as an important habitat for nematodes of the platypus.     

Land or plants: Agricultural tenure in agroforestry systems

The distinction between the rights to land and rights to plants is often overlooked when viewing agricultural tenure in developing countries. This distinction is crucial to understanding traditional agricultural systems, especially where agroforestry is practiced or its introduction has been proposed. Rights to land versus rights to plants are viewed in two Asia-Pacific agroforestry systems: one in Indonesian Borneo and the other in Papua New Guinea. Conflicts are discussed between the traditional dichotomy of land and plant rights and government policy. The success of an indigenous agroforestry system based on plant rights is contrasted to the failure of a proposed agroforestry system for similar reasons. It is concluded that the perceptual separation of land and plant rights needs to be explored if agroforestry practices are not only to be ecologically and economically feasible but also culturally acceptable.     

The Indigo of Commerce in Colonial North America

It can be demonstrated that the Indigo of Commerce in Colonial North America consisted of three species in the genusIndigofera. One of these was a native plant,I. Caroliniana Mill, while the other two were introduced.Indigofera tinctoria L. (French Indigo), an Old World species, andI. Suffruticosa Mill. (Guatemala Indigo), a New World species, were both introduced into South Carolina in the late 17th and early 18th centuries. Their cultivation flourished until the American Revolution. Neither of the introduced species has become naturalized in the Carolinas.
