Intensification of shellfish exploitation: evidence of species-specific deviation from traditional expectations

As modern humans grapple with the repercussions of their extensive environmental impacts, archaeologists are increasingly looking toward the past to understand the nature and extent of prehistoric human impact on the environment. Many researchers rely heavily on archaeological correlates of resource intensification as a proxy measures of resource depletion, a profound and often catastrophic human impact. However, the traditional conceptualization of the archaeological correlates of shellfish intensification disregards a large amount of species-specific variation. This paper presents archaeomalacological data from Santa Cruz Island, California. The shell midden deposits CA-SCRI-480 contain a high density of Tivela stultorum (Pismo clam). Statistical analysis of the shellfish assemblage reveals significant variation in both the size and quantity of Pismo clam that people collected through time. This paper investigates this unique patterning with due consideration of the natural ecology and life history of the species and illustrates species-specific deviation from the traditional archaeological correlates of shellfish intensification. Increased collaboration with ecologists and biologists can help refine models of intensification when necessary in order create more sophisticated understanding of prehistoric human–resource interactions.     

Obsidian sources and distribution systems in Island Southeast Asia: a review of previous research

This paper summarises research on obsidian findings across the region of Island Southeast Asia (ISEA), from the first reporting of obsidian on Sumatra as a result of cave excavations in the early 1900s through to the latest published discoveries in 2009. These results are the background for the first region-wide research project focussing on obsidian characterisation and its role in prehistoric inter-island exchange. It is commonly held that distribution of obsidian in ISEA was only localised and inter-island transportation limited. The review, however, suggests that this hypothesis derives from an incomplete knowledge of obsidian distribution in the region rather than typifying prehistoric social patterns. Obsidian sourcing has been carried out only intermittently in ISEA since the 1970s and has generally been focussed only at the single site level, thus explaining this very partial understanding.     

Red abalone collecting and marine water temperature during the Middle Holocene occupation of Santa Cruz Island,California

Oxygen isotope values derived from prehistoric mussel (Mytilus californianus) shell calcite are used to determine whether sea-surface temperatures in the vicinity of the Punta Arena site (CA-SCRI-109) on Santa Cruz Island, California, were cooler than present between 6300 and 5300 cal BP. This site and others in the western sector of the island dating to this period are distinctive because of the presence of large red abalone (Haliotis rufescens) shells, a species that historically has been subtidal around Santa Cruz and the other northern Channel Islands. Comparison of temperature values derived from archaeological shells with those from modern mussel shells, along with water temperatures derived from satellites, indicates that waters were cooler during the 6300 to 5300 cal BP period. These results are consistent with a previous study and support the interpretation that collection of red abalone during the 6300–5300 cal BP period was partly the result of cooler water temperatures that made this large mollusk more available to foragers in the intertidal or shallow subtidal zone.     

Mapping prehistoric social fields on the Sepik coast of Papua New Guinea: ceramic compositional analysis using laser ablation-inductively coupled plasma-mass spectrometry

The Sepik coast of northern Papua New Guinea is one of the most linguistically diverse places on earth despite communities there currently being connected into wide-reaching social and economic networks that cross language boundaries. One possible explanation for observed human diversity is that social connections were substantially less intensive prior to colonial pacification. As a proxy for human interaction, we compositionally analyzed 287 ceramic sherds from archaeological contexts using laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) to determine their place of production. Our results indicate that ceramics produced on Tumleo Island—currently the most important regional ceramic producer—were transported to other places on the Sepik coast after ∼1000 BP, suggesting that linguistic diversity on the coast has been maintained in an interactive environment for at least a millennium.     

Diet,Geography and Drinking Water in Polynesia: Microfossil Research from Archaeological Human Dental Calculus,Rapa Nui (Easter Island)

Microfossil analysis of human dental calculus provides consumption‐specific and archaeologically relevant data for evaluating diet and subsistence in past populations. Calculus was extracted from 114 teeth representing 104 unique individuals from a late 16^th to early 18^th century skeletal series on Rapa Nui (Easter Island) to address questions of human–environment interactions and possible dietary preference. Scanning electron microscopy was used in lieu of optical microscopy for its superior depth of field and resolution of surface detail. The calculus microfossil recovery produced 16,377 total biogenic silica microfossils: 4733 phytoliths and 11,644 diatoms. The majority of phytoliths correspond with the Arecaceae or palm family (n = 4,456) and the minority corresponds to the Poaceae or grass family (n = 277). Because of the relatively large sample size, we were able to test hypotheses related to age cohort, sex, dental element and geographic region. Results indicate no significant difference in phytolith or diatom recovery based on age cohort or sex. The high frequency and proportion of Arecaceae phytoliths found in calculus extracted from the anterior dentition suggests consumption of soft or cooked foods containing palm phytoliths and the high frequency of diatoms recovered from the southern part of the island argue for different sources of drinking water.

A short note on starch and xylem of Colocasia esculenta (taro) in archaeological deposits from Pitcairn Island,southeast Polynesia

We present results of starch analysis of archaeological deposits from Pitcairn Island. High concentrations of starch grains preserved in cell membranes, and xylem tracheary elements, consistent with introduced Colocasia esculenta (taro) were found. Because of limited age control, we are uncertain if the microfossils are prehistoric. Problems associated with identifying taxa with small starch grains in extractions from weathered deposits are highlighted.     

Global Markets, Local Practice: Ottoman-period Clay Pipes and Smoking Paraphernalia from the Red Sea Shipwreck at Sadana Island, Egypt

Shipwreck archaeology provides unique evidence for trade, commercial relationships, and the day-to-day existence of occupational communities defined by residence and employment within the industrial space aboard a ship. These concerns are addressed particularly well by finds of utilitarian items such as a small assemblage of 21 clay pipes and three other smoking-related artifacts recently excavated from the ca. 1765 Sadana Island ship which sank at anchor while loaded with coffee, porcelain, qulal, and other goods. Analysis of the assemblage specifically contributes to questions of chronology and typology and presents new evidence for regionalism, style, and the impact of far-reaching trade routes on markets with a global perspective.

Pacific Studies in China: Policies,Structure and Research

ABSTRACT

The expansion of Chinese influence in the Pacific has aroused growing attention from academics and policymakers. Although China has established six main Pacific research centres, there has been little investigation into what motivates this increasing interest. Building on the author's recent interviews with 39 Chinese mainstream scholars on the subject of Pacific Studies, this paper aims to fill this gap by providing an in-depth analysis of Pacific Studies in China, especially how centres are structured and what motivated their establishment. It is argued that the initiation, structure and scholarly focus of academic research on the Pacific in China has been largely driven by government policies, but also that government interest has fluctuated under President Xi Jinping. Government policy dependence is a double-edged sword that both promotes and hinders Pacific scholarship.
