Interpreting abundance indices: some zooarchaeological implications of Martu foraging

Indices of taxonomic abundance are commonly used by zooarchaeologists to examine resource intensification, overexploitation and gender-divisions in foraging labor. The original formulation of abundance indices developed a clear interpretive framework by linking the measure with foraging models from behavioral ecology. However, using the same basic tenets of behavioral ecology, archaeologists disagree about how to interpret variability in abundance index values: some suggest that high proportions of large prey remains represent higher overall foraging efficiency, while others argue the opposite. To help solve this problem, we use quantitative observational data with Martu hunters in Australia’s Western Desert to examine how foraging decisions and outcomes best predict variation in the abundance index values that result. We show that variation in the proportional remains of large to small game is best predicted by hunting bout success with larger prey and the time spent foraging for smaller prey. A declining abundance index results from decreasing hunting success with larger prey, increasing time invested in hunting smaller prey, or both; any of which result in a lower overall return rate than if large prey were acquired reliably. We also demonstrate that where large prey acquisition is stochastic, high index values are correlated positively with men’s proportional caloric contribution of large unreliable game, while low index values are correlated with women’s proportional foraging time for small reliable game. We discuss these results with reference to evidence of resource intensification and gender-specific foraging.     

Small prey hunting technology and zooarchaeological measures of taxonomic diversity and abundance: Ethnoarchaeological evidence from Central African forest foragers

Archaeological analyses of faunal assemblages often rely on rationale derived from the prey choice model to explain temporal and spatial changes in taxonomic measures of diversity and/or abundances. In this paper, we present analyses of ethnoarchaeological observations and bone assemblages created by Central African Bofi and Aka forest foragers which show that different small prey hunting technologies target specific suites of prey and that hunters vary their technological choice depending on their foraging goals. Analysis of ethnoarchaeological bone assemblages produced by the Bofi and Aka shows that variability in target prey can create spatially distinct, but contemporaneous, faunal assemblages with different diversity values and abundance indices. These data reveal important variation in how individuals within a contemporary human population rank prey and challenge current assumptions about the meaning of diversity and abundances measures in archaeological contexts. We argue that the use of diversity and abundance indices can obscure important intrasite variability in prehistoric foraging effort and suggest strategies that might enhance current techniques.

Explaining prehistoric variation in the abundance of large prey: A zooarchaeological analysis of deer and rabbit hunting along the Pecho Coast of Central California

Three main hypotheses are commonly employed to explain diachronic variation in the relative abundance of remains of large terrestrial herbivores: (1) large prey populations decline as a function of anthropogenic overexploitation; (2) large prey tends to increase as a result of increasing social payoffs; and (3) proportions of large terrestrial prey are dependent on stochastic fluctuations in climate. This paper tests predictions derived from these three hypotheses through a zooarchaeological analysis of eleven temporal components from three sites on central California’s Pecho Coast. Specifically, we examine the trade-offs between hunting rabbits (Sylvilagus spp.) and deer (Odocoileus hemionus) using models derived from human behavioral ecology. The results show that foragers exploited a robust population of deer throughout most of the Holocene, only doing otherwise during periods associated with climatic trends unfavorable to larger herbivores. The most recent component (Late Prehistoric/Contact era) shows modest evidence of localized resource depression and perhaps greater social benefits from hunting larger prey; we suggest that these final changes resulted from the introduction of bow and arrow technology. Overall, results suggest that along central California’s Pecho Coast, density independent factors described as climatically-mediated prey choice best predict changes in the relative abundance of large terrestrial herbivores through the Holocene.     

Dynamics of pioneer colonisation in the Early Iron Age in the Duero basin (Central Iberia,Spain): Integrating archaeological and palynological records

Abstract

This study addresses the earliest strategies of permanent occupation in the mountainous regions bordering Northern Meseta in inland Iberia. This piece of work gathers together and discusses archaeological information about settlement in the Late Bronze Age and Early Iron Age and previously published high-resolution palynological cores from three study areas. Its major goal is to assess both archaeological and pollen records in order to gain a better understanding of the dynamics of occupation and transformation of these upland settings. Until cal 700 BC there are no clear signs of permanence in the highlands surrounding the Duero basin, but from that point onwards various initiatives of small-scale spontaneous colonisation have been identified. Colonisation in the Iron Age involved pastoralism, cereal agriculture and a significant use of forestry resources, causing a major anthropogenic impact with irreversible consequences. The outlined account constitutes the first synthetic overview at a macro-regional scale on the beginnings of the integrated and diversified strategies implemented in these upland regions.     

Of stones and bones: Interpreting site function in the Upper Paleolithic and Mesolithic of Western Europe

Upper Paleolithic and Mesolithic excavations have usually yielded both artifacts and faunal remains in a variety of environmental settings across a latitudinal range from Belgium to Portugal. In some cases there seem to be functional relationships within levels between ungulate species and skeletal elements on the one hand and associated lithic and osseous artifacts on the other. In other cases—perhaps because of their nature as occupational and depositional palimpsests—the relationships are murkier. Examples examined here include La Riera and El Mirón caves (coastal and montane Cantabrian Spain, respectively), Dufaure rockshelter (Pyrenean lowland France), Magrite cave, Pape rockshelter, and Bois Laiterie cave and the Huccorgne open-air site (Ardennes upland, transitional zone, and central plateau of Belgium, respectively), and the Vidigal shell midden (coastal southern Portugal). The interpretation of site function (e.g., multi-purpose residential site, specialized logistical camp, or transit bivouac) is a matter of pragmatic, interdisciplinary, situation-specific analyses, and parsimony.     

Brands of youth citizenship and the politics of scale: National Citizen Service in the United Kingdom

This paper explores the politics of scale in the context of youth citizenship. We propose the concept of ‘brands of youth citizenship’ to understand recent shifts in the state promotion of citizenship formations for young people, and demonstrate how scale is crucial to that agenda. As such, we push forward debates on the scaling of citizenship more broadly through an examination of the imaginative and institutional geographies of learning to be a citizen. The paper's empirical focus is a state-funded youth programme in the UK – National Citizen Service – launched in 2011 and now reaching tens of thousands of 15–17 year olds. We demonstrate the ‘branding’ of youth citizenship, cast here in terms of social action and designed to create a particular type of citizen-subject. Original research with key architects, delivery providers and young people demonstrates two key points of interest. First, that the scales of youth citizenship embedded in NCS promote engagement at the local scale, as part of a national collective, whilst the global scale is curiously absent. Second, that discourses of youth citizenship are increasingly mobilised alongside ideas of Britishness yet fractured by the geographies of devolution. Overall, the paper explores the scalar politics and performance of youth citizenship, the tensions therein, and the wider implications of this study for both political geographers and society more broadly at a time of heated debate about youthful politics in the United Kingdom and beyond.     

Sailing and Sailing Rigs in the Ancient Mediterranean: implications of continuity,variation and change in propulsion technology

Ships and boats form the foundations of the maritime connectivity that is a central part of our understanding of the ancient Mediterranean. While the general chronological sequence of sail and sailing‐rig development is well established, the implications are less‐well discussed. This article sets out how sails and sailing rigs developed in antiquity, with emphasis on the Greco‐Roman world. Subsequently, instances of innovation are defined. Why specific pieces of maritime technology were, or were not, widely adopted is considered. Long‐term technological continuity can be comprehended, and a shared maritime culture of sailing in the ancient Mediterranean is suggested.
