Published: January 2013

AbstractBackground:Within the myelodysplastic/myeloproliferative neoplasm (MDS/MPN) category of the WHO (2008), only chronic myelomonocytic leukemia was so far evaluated by multiparameter flow cytometry (MFC).Methods:To investigate the potential of MFC for MDS/MPNs, unclassifiable (MDS/MPNu), and refractory anemia associated with ring sideroblasts and marked thrombocytosis (RARS‐T), we studied 91 patients with these entities (60 males/31 females; 35.3–87.4 years) for MDS‐related aberrant immunophenotypes (≥2 different cell lineages with ≥3 aberrantly expressed antigens). Data were correlated with cytomorphology and cytogenetics.Results:MFC identified MDS‐related immunophenotypes in 54/91 (59.3%) of patients. Patients with or without MDS‐related immunophenotype did not differ significantly by demographic characteristics, blood values, or median overall survival. MDS‐related immunophenotype cases showed a higher number of aberrantly expressed antigens (mean ± SD, 4.9 ± 2.4 vs. 2.0 ± 1.4; P < 0.001). Aberrant karyotypes showed a similar frequency in patients with and without MDS‐related immunophenotype (11/54; 20.4% vs. 7/37; 18.9%; P = n.s.).Conclusions:MDS‐related immunophenotype are present in more than half of patients with MDS/MPNu and RARS‐T. MFC therefore may be helpful to separate cases into more “MDS‐like” or “MPN‐like” subgroups. © 2012 International Clinical Cytometry Society
An ecohydrological review of dune slacks on the west coast of England and Wales
Authors: Stratford C. J. , Robins N. S. , Clarke D. , Jones L. , Weaver G. 
Published: January 2013

ABSTRACTCoastal dunes are valuable ecological reserves providing a range of ecosystem services from coastal flood defence to recreational amenity. An important feature of dune systems is the slack floors, areas of high ecological value that are closely linked to the prevailing hydrological system in the dunes. Dune slacks are sensitive environments that are impacted by external changes, such as rainfall patterns and foreshore erosion as well as conservation management. Understanding the effects of these influences upon the water balance in a dune system is fundamental to the management of the slacks. Occurrence of seasonal flood depths, area and timing and how far the water table recedes below ground in summer are critical to the flora and fauna that the slacks will support. Change in the hydrological regime directly impacts the ecosystem. Experience is drawn from four sites in Wales and west coast England: Ainsdale on the Sefton Coast, Newborough Warren in North Wales, Whiteford Burrows in South Wales and Braunton Burrows in North Devon. Similarities and differences between the hydroecology of the respective sites highlight common mechanisms and processes and those unique to each site. Copyright © 2013 John Wiley & Sons, Ltd.

ABSTRACTKnowledge of the relationship between soil water dynamics and tree water use is critical to understanding forest response to environmental change in water‐limited ecosystems. However, the dynamics in soil water availability for tree transpiration (Tt) cannot be easily deduced from conventional measurements of soil water content (SWC), notably because Tt is influenced by soil water potential (Ψs) that, in turn, depends on soil characteristics. Using tree sap flow and water potential and deriving depth‐dependent soil water retention curves, we quantified the ‘transpirable soil water content’ (tSWC) and its seasonal and inter‐annual variations in a semi‐arid Pinus halepensis forest. The results indicated that tSWC varied in time and with soil depth. Over one growing season Tt was 57% of rain and 72% of the infiltrated SWC. In early winter, Tt was exclusively supported by soil moisture at the top 10 cm (tSWC = 11 mm), whereas in spring (tSWC > 18 mm) and throughout the dry season, source water for Tt shifted to 20–40 cm, where the maximum fine root density occurs. Simulation with the soil–plant–atmosphere water and energy transport model MuSICA supported the idea that consistent tSWC at the 20–40 cm soil layer critically depended on limited water infiltration below 40 cm, because of high water retention below this depth. Quantifying tSWC is critical to the precise estimation of the onset and termination of the growing season (when tSWC > 0) in this semi‐arid ecosystem. Copyright © 2013 John Wiley & Sons, Ltd.

Gold(I)‐Catalysed Alkene Cycloaddition Reactions of Propargyl Acetals
Authors: Iqbal Naseem , Sperger Christian A. , Fiksdahl Anne 
Published: January 2013

AbstractStudies on gold(I)‐catalysed reactions of propargyl acetals are scarce, unlike those of the corresponding esters. We have investigated gold(I)‐catalysed cyclization reactions of both propargyl acetals and esters in order to identify the abilities of the two substrate groups to follow two different cyclization pathways with vinylic reactants, such as vinyl amides and vinyl ethers, in chemoselective manner. Corresponding reactions with indoles allowed the construction of biologically interesting polycyclic indole‐based compounds. The relative reactivities of propargyl acetals and esters were also studied. The gold(I)‐catalysed cyclization reactions of propargyl acetals were characterized by two important features: i) in contrast with the conventional olefin cyclopropanation that normally takes place with propargyl esters, the favoured general reaction pathway for the corresponding acetals is an atypical cyclopentenylation by [2+3] cycloaddition to afford trans‐cyclopentenyl products, and ii) the propargyl acetals showed significantly higher reactivities than the corresponding esters, in line with the assumption that the alkoxy substituent might activate the gold‐propargyl acetal complex intermediate. Different factors affecting the specific pathways are discussed, with the aim of achieving better mechanistic understanding of the reactions.
A Matter of Balance: An overview of Pleistocene occupation history and the impact of the Last Glacial Phase in East Timor and the Aru Islands, eastern Indonesia
Authors: O'CONNOR SUE , APLIN KEN 
Published: January 2013

AbstractThis paper explores the subsistence records from cave sites with Pleistocene‐aged deposits in East Timor and the Aru Islands during the Last Glacial Maximum (LGM), and discusses these records within the context of the limited archaeological evidence for LGM occupation from elsewhere in the Indonesian Archipelago. Although Timor and the Aru Islands are at similar latitudes, the onset of aridity had markedly different impacts on the settlement and subsistence choices available to hunter‐gatherers in these two regions. We suggest that the different occupation trajectories seen in Timor and Aru during the LGM are related, at least in part, to biogeographic contrasts across the Indonesian Archipelago.
Climate variability in the mid to late Holocene Arnhem Land Region, North Australia: Archaeological archives of environmental and cultural change
Authors: BOURKE PATRICIA , BROCKWELLM SALLY , FAULKNER PATRICK , MEEHAN BETTY 
Published: January 2013

AbstractA number of archaeologists have suggested that significant climatic change with environmental and social consequences occurred between 1000 and 400 years ago in the Indo‐Pacific region. We investigate this premise by examining the archaeological record of changes in hunter‐gatherer economies in three geographically distinct coastal regions of tropical northern Australia. These case studies support the argument that Aboriginal mollusc exploitation reflects the altered local ecological habitats that accompanied broader coastal environmental change over the last few thousand years. Overlap between the phases and timing of climatic and behavioural changes within each region suggests that, given regional variation in the nature and of these changes, there was an associated human response to late Holocene climatic variability.These case studies establish that archaeological and environmental evidence mutually support the argument for climate change influencing cultural change in northern Australia. We suggest that, while a direct physical link between environmental change and the interpretations of significant cultural change in the archaeological record have yet to be demonstrated unambiguously in this region, the analysis of mollusc exploitation has the potential to provide the direct link that is currently missing between changes in climate, environment and human responses over the last millennium.
Assessing the role of climate change and human predation on marine resources at the Fatu‐ma‐Futi site, Tutuila Island, American Samoa: an agent based model
Authors: MORRISON ALEX E. , ADDISON DAVID J. 
Published: January 2013

AbstractIn the tropical Pacific, climate change has been implicated as a causal variable in the development of a variety of social processes, including resource scarcity, cultural diversification, changes in spatial organization, and conflict. Hypotheses concerning the effects of climatic variability on cultural change can be better evaluated once links between environmental processes and subsistence patterns are established. Here we present data on approximately 1500 years of shellfish exploitation at the Fatu‐ma‐Futi site, Tutuila Island, American Samoa. We generate an Agent Based Model to test hypotheses regarding resource exploitation and the effects of climate change on near‐shore marine fauna. To date, little archaeological data regarding prehistoric marine resource use in Samoa is available, demonstrating the need for more field research. Integrating models generated from foraging theory and agent based computer simulations provides a new technique for modeling social and ecological processes in complex environments.
Distribution and variation in sago extraction equipment: convergent and secondary technologies in island southeast Asia
Authors: ELLEN ROY 
Published: January 2013

AbstractIt is argued, following François Sigaut, that the way elements of technology are invented, borrowed and re‐combined challenges the notion of ‘technical lineage’, with its implication of ‘successive orderly accretions’. The contention is examined in relation to pith removal equipment used in palm starch extraction in island southeast Asia and Melanesia, which is considered additionally instructive because it yields some potential archaeological traces. The key archaeotypes—pounding and rasping tools—reflect convergent and secondary technologies that most likely were adapted to sago processing from other cultural domains. Pounders are found mainly in the eastern part of the geographic range, and rasps in the west. There is much variability in the distribution of types, even within a small area. Inferences are drawn relating to recent changes (for example, from stone to metal working edges, and from pounders to rasps), and concerning what we can learn from the distribution of different kinds of tool, including the likelihood of versions of the same tool co‐existing in the same place, or being independently invented at opposite ends of the archipelago.
A small salvage excavation in Windjana Gorge, Kimberley, Western Australia
Authors: O'CONNOR SUE , APLIN KEN , COLLINS SOPHIE 
Published: January 2013

AbstractWindjana Gorge Water Tank Shelter (DIA 12588) is a narrow limestone rockshelter located in Windjana Gorge National Park, Western Australia. Although the site is badly disturbed, test excavation revealed some 45cm of in situ deposit down to massive roof‐fall. Radiocarbon estimates demonstrate that the shelter was used from at least 7000 calBP into the European contact period. The sediments contain well‐preserved faunal remains and stone artefacts. The faunal remains give an insight into Aboriginal economy in an arid region with adjacent fresh water sources.
Anything more than a picnic? Re‐considering arguments for ceremonial Macrozamia use in mid‐Holocene Australia
Authors: ASMUSSEN BRIT 
Published: January 2013

AbstractInfluential arguments have been advanced in Australian archaeology concerning the origins and development of social and economic change in the mid‐late Holocene (Lourandos 1997). One example used to support this claim is the perceived existence of ceremonial feasting events held in the semi‐arid and rugged sandstone gorge systems of central Queensland, attended by large groups of people for extended periods, and underwritten by large quantities of kernels from the cycad Macrozamia moorei (Beaton 1977, 1982; see also Lourandos 1997). However the re‐examination of the macrobotanical evidence from archaeological sites in this region using taphonomic analysis, replicative processing experiments, recalculations of seed density and estimations of the minimum numbers of seeds, does not support this model. This re‐examination questions the role of Macrozamia seeds in the context of socio‐economic change and suggests new interpretations of Macrozamia resource use.
Pre‐Austronesian dispersal of banana cultivars West from New Guinea: linguistic relics from Eastern Indonesia
Authors: DENHAM TIM , DONOHUE MARK 
Published: January 2013

AbstractAgainst the backdrop of a comprehensive archaeobotanical review, we present linguistic evidence that allows us to develop a model of the dispersal of bananas westwards from New Guinea. This westward dispersal is a window on pre‐Austronesian contact between New Guinea and regions to the west. The linguistically‐derived model is compatible with archaeobotanical and botanical data. Our interpretation accords with evidence for maritime interactions from the early Holocene in western New Guinea and eastern Indonesia.
Worked Shell from Leta Leta Cave, Palawan, Philippines
Authors: SZABÓ KATHERINE , RAMIREZ HAZEL 
Published: January 2013

AbstractThe Leta Leta Cave burial site is a distinctive and enigmatic site of the Philippine Neolithic, excavated by Robert Fox. Containing a number of burials, its unusual earthenware pottery — including the ‘yawning‐mouth vessel’, small footed goblets and a cut‐out pedestalled bowl — have seen it recognised in the Philippines as an official site of national significance. In addition to the human remains and earthenware, Fox recovered a sizeable assemblage of shell artefacts which, as with other material remains recovered from Leta Leta, were only cursorily reported in print before his death. Recent analysis of the Leta Leta worked shell has revealed the deposition of unfinished as well as finished shell artefacts in mortuary contexts. As well as giving rare insights into manufacturing protocols in an island where the Neolithic and Metal Age records are characterised virtually solely by mortuary deposits, the deposition of unfinished artefacts opens new avenues for the discussion of Neolithic mortuary practices in Palawan. Results of a study of the worked shell assemblage, in addition to recent radiocarbon determinations for the site, are presented here.
Coastal shell middens of the Abydos coastal plain, Western Australia
Authors: CLUNE GENEVIEVE , HARRISON RODNEY 
Published: January 2013

AbstractMiddens and mounds dominated by Anadara granosa began to be formed on the Abydos Coastal Plain sometime between 4400 and 5300 calibrated years before present, and while mounds appear to have ceased forming some 1800–1600 years ago, middens continued to form until the early twentieth century or later. In some cases, the earliest of these middens and shell mounds formed on top of older middens from which Anadara granosa is totally absent, and in which Terebralia spp. (while occurring in relatively low concentrations) is the dominant shell species. Anadara granosa dominated middens (sensu lato) occur in a variety of forms across the landscape, including large shell mounds, earth mounds (or mounded shell middens), lenses of shell eroding out of well‐developed dunes, and undifferentiated surface shell scatters. The large number of middens which occur throughout the region from the mid Holocene, and the volume of shell represented by these sites, point to the occurrence of significant economic and social changes from the mid to late Holocene. The Abydos Coastal Plain experienced increasing aridity, and, as a result, increased resource stress during the mid‐Holocene. We suggest that the large, single species Anadara granosa middens were occupied during regular periods when large groups of Aboriginal people undertook ceremonial activities after the wet season, when resources were abundant. Changes apparent in the archaeological record, including the occurrence of large numbers of Anadara granosa dominated middens and shell mounds, increased establishment of archaeological sites and increased complexity and distance of exchange systems, came about as a result of social, economic and logistical restructuring. This in turn was the result of the effects of resource stress on local Aboriginal people over the course of the mid to late Holocene.
Indigenous perceptions of contact at Inthanoona, Northwest Western Australia
Authors: PATERSON ALISTAIR , WILSON ANDREW 
Published: January 2013

AbstractInthanoona, a pastoral head station in the Pilbara region of Western Australia, which functioned from the 1860s to the 1890s includes an assemblage of more than 250 rock engravings of which 20% are identifiable contact period motifs. These include images of clothed men and women, guns, horses, sheep, wheeled vehicles, houses and ships. Spatial analysis of the structures, artefacts and engravings on the site supports the conclusion that the contact motifs demonstrate continuity in Indigenous modes of representation and innovation in subjects. They provide direct evidence of Aboriginal participation in, and perceptions of, the pastoral and pearl shell industries of the Pilbara.
Rethinking Polynesians origins: A West‐Polynesia Triple‐I Model
Authors: ADDISON DAVID J , MATISOO‐SMITH ELIZABETH 
Published: January 2013

AbstractThe last twenty years has seen an apparent consensus that the immediate origins of Polynesian language, culture and biology lie solely with the Lapita peoples and cultures that settled Samoa and Tonga by 2700 years ago. We suggest that there is increasing evidence that does not sit well with this generally accepted view of Polynesian origins and thus we put forward an alternative model for consideration. Building on Green's suggestion of over 20 years ago, we propose that some of the ideas in his Triple‐I model (Green 1991a) might also be usefully applied to conceptualizing the processes involved in Polynesian origins. Specifically, we suggest that in addition to Lapita origins, there were significant later elements introduced to Polynesia that were fundamental to the development of Polynesian culture and biology prior to the settlement of East Polynesia. Current data suggest that some of these elements are shared with Micronesia and may be ultimately derived from post‐Lapita population movements, perhaps from Island Southeast Asia through the low islands of the Carolines, Kiribati and Tuvalu to West Polynesia.
A reanalysis of the Tikopia obsidians
Authors: SPRIGGS MATTHEW , BIRD ROGER , AMBROSE WAL 
Published: January 2013

AbstractIn 1982 an initial sourcing of 13 obsidians and volcanic glasses from Tikopia in the Solomon Islands suggested that four specimens came from Bismarcks sources, with Talasea in West New Britain being the most likely, and the rest came from the Banks Islands. Reanalysis now attributes ten pieces to Banks Islands sources and three to sources in the Admiralty Islands.
Last millennium climate change in the occupation and abandonment of Palau's Rock Islands
Authors: CLARK GEOFFREY , REEPMEYER CHRISTIAN 
Published: January 2013

AbstractThe role of AD 1300 climate change in widespread societal change in Palau and the Pacific Basin has recently been debated by Fitzpatrick (2010, 2011) and Nunn and Hunter‐Anderson (2011). The central proposition examined here is the link between a sea‐level driven food crisis and the outbreak of conflict, which is hypothesized in the AD 1300 event model to have led people to shift from unprotected coastal parts of large islands (e.g. volcanic Babeldaob) to more readily defensible offshore islands (e.g. limestone ‘Rock Islands’) during the transition between the Medieval Warm Period (MWP) and the Little Ice Age (LIA). Revision of radiocarbon dates from village sites in the Rock Islands suggests instead that permanent settlements were established on small offshore islands during the MWP with village abandonment during the LIA. Palaeoclimate records from equatorial islands show that during the LIA Palau had less rainfall from the southward movement of the Intertropical Convergence Zone (ITCZ). The abandonment of multiple limestone islands by a population estimated at 4000–6000 people may have been influenced by decreased precipitation and more tentatively from a decline in near‐shore marine foods as a result of sea‐level fall.
Morphological and chemical analysis of archaeological fish otoliths from the Lower Murray River, South Australia
Authors: DISSPAIN MORGAN C.F. , WILSON CHRISTOPHER J. , GILLANDERS BRONWYN M. 
Published: January 2013

AbstractWe analysed otoliths from excavations along the Lower Murray River (n=24), dating from the mid‐ to late‐Holocene period. We identified the species, and estimated the size and age of fish. The potential habitat that fish used throughout their life was estimated from chemical information in the otoliths. The majority of the fish (identified as Maccullochella peelii n=22 and Macquaria ambigua n=2) were caught in freshwater environments during the warm season, and had grown to an age and size indicative of sexual maturity. These observations accord with Ngarrindjeri oral tradition concerning sustainable management strategies. Data indicate that M. peelii grew to a significantly larger size than present fish; historical data suggests this size reduction may be the result of European fishing practices, introduced species and habitat degradation. The study demonstrates the unique nature of otoliths and their potential for investigating Indigenous subsistence strategies.
