The effect of a top predator on kangaroo abundance in arid Australia and its implications for archaeological faunal assemblages

The dingo has received considerable attention in the Australian archaeological literature as an agent of bone fragmentation and accumulation. Dingoes have also been studied with respect to their commensal relationship with Aboriginal people. Study has not been directed, however, to the meta-role of dingoes as prey regulators that suppress kangaroo abundance, and the subsequent impact on human subsistence that direct competition between dingoes and humans over the same animal resources could have produced. This study presents data gathered in two adjacent cultural landscapes defined by human land use, one with dingoes and one without dingoes – to illustrate the archaeological effect that dingoes may have had on human economic systems by suppressing kangaroo abundance. Live kangaroos and kangaroo skeletal remains were on average 14-fold and 32-fold more abundant in the absence of dingoes, and contemporary commercial kangaroo harvesting and sheep grazing were restricted to areas where dingoes were absent. Given the marked effects that dingoes have on contemporary kangaroo abundance and the human economy, we argue that dingoes likely shaped the human economy in the past through human–dingo competition for the same limited resources. Evidence for competition between humans and dingoes could be investigated in the archaeological record by comparing the relative frequency of prey of different body sizes, as well as the degree of fragmentation of kangaroo skeletal elements, before and after the arrival of dingoes.     

Distinguishing between archaeological sheep and goat bones using a single collagen peptide

We describe a method of isolating and analyzing a single collagen peptide able to distinguish between sheep and goat bone collagen. The 33 amino acid peptide from both sheep and goat collagen was sequenced and shown to differ between the two species at two positions. Analysis of a range of caprines indicated that the sequence changes occurred between the divergence of the Himalayan tahr (Hemitragus jemlahicus) and the ibex (Capra ibex) and that the proposed goat marker is diagnostic of all Capra species and breeds. The survival of these markers in archaeological bones was tested using a set of 26 ovicaprid specimens from Domuztepe, a Neolithic site in south central Turkey. These markers were used to test the osteological determination of 24 of the Domuztepe bones, and determine the species for two immature specimens. The collagen-peptide method has advantages over other non-morphological methods of sheep/goat distinction because of the long-term survival of collagen over other biomolecules such as ancient DNA. The results also highlighted the problems in relying upon one morphological criterion, in this case on the distal radius, to distinguish between sheep and goat bones.     

GIS-based modeling of drought and historical population change on the Canadian Prairies

This article describes the development of a GIS-based model of historical drought and population change in western Canada, designed to support qualitative field research into drought adaptation and migration. The model combines digitized census data and recently available modeled historical climate data at a 10 km² grid cell scale and can be used to generate maps of ‘hotspots’ where historical declines in rural populations may be associated with extended periods of heat and lack of precipitation. The results suggest a promising avenue for expanding and refining GIS-based modeling of historical human–climate interactions to support qualitative research and to potentially serve as a stepping stone toward forecasting future risk areas of drought-related migration in continental dryland areas.     

Cattle mobility in prehistoric Britain: strontium isotope analysis of cattle teeth from Durrington Walls (Wiltshire,Britain)

An important role has been envisaged for cattle during the Neolithic period in Britain based on their prominence within the faunal assemblages of the period as a whole. The relative ease with which cattle can be moved over long distances and the requirement to provide ample pastureland leads almost inescapably to the consideration of prehistoric cattle movement. This paper presents the results of an investigation into the mobility of Late Neolithic cattle at the well-known site of Durrington Walls, Wiltshire. ⁸⁷Sr/⁸⁶Sr values from cattle (Bos taurus) teeth were compared to local vegetation samples, well established values from archaeological material and to known geological conditions in order to determine whether individual animals were raised in areas with similar geological conditions as those found at the site (i.e. chalkland), and therefore whether the animals were of allochthonous or autochthonous origin. In total, 13 mandibular molars from Durrington Walls were analysed. Two of the animals included in the study were certainly raised under conditions similar to those found in the vicinity of Durrington Walls, but the other 11 provided signatures so distinct from that found locally that they could not have been raised on chalkland. From the results it is suggested that cattle were brought to the site from a variety of grazing areas in different parts of Britain. The implication of these findings is that the movement of cattle was undertaken during the Late Neolithic, and that in a number of cases substantial distances must have been traversed in order for animals to reach the site. In addition, the study provided valuable information for the interpretation of the site, which attracted people from a variety of regions, probably for ceremonial reasons.     

Palaeohabitat of first settlement sites 1500–1000 B.C. in Guam,Mariana islands,western Pacific

Based on computer-aided models and geoarchaeological excavations, palaeohabitat renderings can account for ancient site locations and contexts much different from today in terms of sea level, coastal dynamics, slope erosion, nearshore ecosystems, native forests, and other factors. A case study illustrates this research in Guam of the Mariana Islands of the western Pacific, with specific reference to the 1500–1000 B.C. time interval. This time interval includes the oldest known archaeological sites in the Mariana Islands, directly relevant for understanding the context of ancient Austronesian population dispersals in the larger western Pacific region. The results also help toward larger understanding of coastal adaptations in dynamic settings.     

Fish ’n chips: ZooMS peptide mass fingerprinting in a 96 well plate format to identify fish bone fragments

Fish are a large, highly diverse, and anthropologically important group of vertebrates. However, fish bones are underrepresented in the archaeological literature because they are less stable than those of other taxa and identification of bone to species is often difficult or impossible. We explore a new identification system, ZooMS (Zooarchaeology by Mass Spectrometry), which is based upon protein barcoding. As proteins can be cleaved enzymatically and analyzed by mass spectrometry in a repeatable way, protein barcoding is used widely in microbiological contexts for quick and inexpensive protein identification; mass spectra reflect the differences in protein sequence and can therefore be reproducibly linked to a particular protein or protein fragment. ZooMS uses peptide fingerprinting of bone collagen as a method for rapid identification of archaeological bone. This has involved the identification of masses related to peptides of known sequence. For mammals, sufficient sequence information is available for this approach but for groups, such the teleost fish, species are highly diverse and there are few available collagen sequences. Here we report a preliminary investigation into the identification of fish species by peptide mass fingerprinting that does not require sequence information. Collagen mass spectra are used to identify eight species of bony fishes (Osteichthyes) from four orders: Clupeiformes, Salmoniformes, Gadiformes, and Perciformes. The method is applied to both modern and archaeological fish remains and offers the capacity to identify traditionally unidentifiable fish fragments, thus increasing the Number of Identified Specimens (NISP) and providing invaluable information in specialized contexts.     

Sex ratios and life tables: Historical demography of the age at which women outnumber men in seven countries, 1850–2016

Abstract

The male/female sex ratio (SR) and its age-specific patterns vary considerably across time and place. The SR generally begins male-biased at birth and becomes female-biased later in life, but this relationship should respond to historical trends and events. Temporal trends in SRs remain largely unstudied and formal demographic relationships are not well defined. We (1) define SRs in a life table framework, (2) estimate the age at which the number of males and females achieves parity—the sex ratio crossover (SRX)—using basic life table methods, and (3) explore historical and international patterns in these trends. Using publicly-available data from the Human Mortality Database, we construct SR and SRX measures from period and cohort life tables. Analyses explore temporal patterns for seven countries in different global regions since 1850. Overall temporal trends show the SRX advancing to older ages. The SRX also appears to respond to historical events such as wars and epidemics. The measure is simple to construct from life table data, and provides additional insight into the historical context of gender dynamics.     

A charcoal-rich horizon at Ø69, Greenland: evidence for vegetation burning during the Norse landnám?

It is often assumed that the colonisation of Greenland by Norse settlers in c. A.D. 985 had a sudden and dramatic effect on the environment, involving substantial vegetation clearance and environmental degradation. Consequently, it has been argued that charcoal-rich horizons, visible in many sections in Greenland, represent the initial burning of the vegetation by Norse farmers to create land suitable for agriculture. In this study a charcoal-rich layer, visible in a modern drainage ditch beside the Norse farm of Ø69, was analysed using archaeobotany, sedimentary analysis and radiocarbon dating to test the date and formation processes of the horizon. It is demonstrated that the charcoal-rich layer at Ø69 was not derived from in situ vegetation burning in the 10th century and concluded that the layer was probably formed by the addition of midden material to the infields around Ø69 in the 13th and 14th centuries cal AD, perhaps as part of a soil amendment strategy. It is argued that caution must be exercised when interpreting charcoal-rich horizons as time-specific chronological markers in palaeoenvironmental sequences in Greenland.     

HM Ship Roebuck (1690–1701): Global Maritime Heritage?

William Dampier, his literature, and the associated archaeological remains, notably HM ship Roebuck, are of undoubted global significance. While there are acknowledged legal rights to the remains in respect of the Crown, and of Ascension Island where Roebuck was lost, there also exists a number of nations possessing an interest in this famous 'pirate and hydrographer' and his ship. Australia is one of those nations and in March 2001 a team under the auspices of the Western Australian Maritime Museum conducted research, search and survey aimed at finding out more about William Dampier and his lost ship. This is a precis of their results.

Russia and Chechnya: the issue of secession*

Abstract. This paper considers the Chechen secessionist struggle against Russia. Although the Chechens had good moral grounds for claiming independence in November 1991, this paper shows that Yeltsin also had reasons, defensible in legal terms and liberal secessionist theory, for rejecting it. Even if Moscow had granted Chechnya independence, this would not have created peace and stability. Moscow had a right to defend its territorial integrity, but its conduct in the war has proved counter‐productive. It has polarised opinion in Chechnya and made any solution to the crisis more difficult to achieve. On paper, Moscow's longstanding proposal of political autonomy for Chechnya looks the best way forward, but it is unlikely to satisfy Chechen nationalists or the Islamic fundamentalists who have more expansionist aims.
