Leporid (rabbit and hare) bones have been shown to yield important information about subsistence practices, mobility patterns, and demographic trends during the Paleolithic of the western and eastern Mediterranean regions. Studies of Spanish Paleolithic caves rich in rabbit bones suggest that residential mobility patterns influence the degree of leporid hunting through time. Studies of Paleolithic sites in the eastern Mediterranean suggest that leporids were hunted in large numbers only after population sizes and densities reached certain thresholds. This paper reviews and critiques these studies based on current taphonomic and ecologic information about leporids. Leporid hunting during the Upper Paleolithic of central Portugal is then discussed and compared to these existing models. These latter data suggest that rabbit hunting in central Portugal does not conform to any existing model, suggesting that local factors of leporid density and environmental conditions likely influenced the nature and timing of small game acquisition during the Upper Paleolithic.  相似文献

Large river valleys have long been seen as important factors to shape the mobility, communication, and exchange of Pleistocene hunter-gatherers. However, rivers have been debated as either natural entities people adapt and react to or as cultural and meaningful entities people experience and interpret in different ways. Here, we attempt to integrate both perspectives. Building on theoretical work from various disciplines, we discuss the relationship between biophysical river properties and sociocultural river semantics and suggest that understanding a river’s persona is central to evaluating its role in spatial organization. By reviewing the literature and analyzing European Upper Paleolithic site distribution and raw material transfer patterns in relation to river catchments, we show that the role of prominent rivers varies considerably over time. Both ecological and cultural factors are crucial to explaining these patterns. Whereas the Earlier Upper Paleolithic record displays a general tendency toward conceiving rivers as mobility guidelines, the spatial consolidation process after the colonization of the European mainland is paralleled by a trend of conceptualizing river regimes as frontiers, separating archaeological entities, regional groups, or local networks. The Late Upper Paleolithic Magdalenian, however, is characterized again by a role of rivers as mobility and communication vectors. Tracing changing patterns in the role of certain river regimes through time thus contributes to our growing knowledge of human spatial behavior and helps to improve our understanding of dynamic and mutually informed human-environment interactions in the Paleolithic.  相似文献

Recent urbanization trends reflect an increasing dependence on regional economic transformations, local population dynamics, and planning constraints, becoming intrinsically complex and nonlinear. Following this assumption, the present study proposes a new approach for the analysis of long-term urban expansion in a compact metropolitan region (Athens, Greece), clarifying the importance of spatial heterogeneity and volatility in building activity over more than one century. A spatially explicit statistical approach was used to define a development cycle reflecting the stratification of heterogeneous waves of compact and dispersed urbanization at municipal scale. While resulting in distinctive spatial patterns of building activity, long-term urban growth emerged as a multifaceted response to market stimuli, social change, and diversified territorial contexts. Results of a spatially explicit analysis of long-term urban expansion based on official statistics shed further light on processes of metropolitan growth and change, and contribute to design integrated strategies enhancing spatial coordination and a more balanced socioeconomic development of contemporary cities.  相似文献

ABSTRACT This paper uses plant‐level EPA and Census data to examine spatial factors affecting environmental performance, as measured by air pollutant emissions and regulatory compliance. We find significant effects for compliance, but not for emissions. Compliance is positively spatially correlated, partly explained by spatial correlations in observed plant characteristics, suggesting influences of industry agglomeration. The use of spatial econometric methods shows only small effects of spatially lagged compliance status, and does not greatly change the estimated contributions of other spatially explicit factors. Regulatory activity has the expected effect of increasing environmental performance, both at the inspected plant and at neighboring plants, but only for plants in the same state, demonstrating the importance of jurisdictional boundaries.  相似文献

We propose a reassessment of Neandertal mobility strategies by crossing technological and zooarchaeological data. A broad comparative approach to the Middle Paleolithic series from western France shows that the Levallois and laminar flaking systems, the Mousterian of Acheulian Tradition (MTA) shaping system and the Quina and discoidal-denticulate flaking systems, vary significantly in terms of duration of reduction sequences, blank versatility and tool maintenance. These technological systems, which prevail in this context over different time periods, reflect distinct mobility strategies as a response to differing hunting practices. This new approach to Middle Paleolithic technologies and related mobility patterns gives new insights into Mousterian diversity. It also highlights the determinant role played by large game hunting strategies in the organization of late Neandertal societies.  相似文献

This paper formulates a multiple discrete‐continuous probit (MDCP) land use model within a spatially explicit economic structural framework for land use change decisions. The spatial MDCP model is capable of predicting both the type and intensity of urban development patterns over large geographic areas, while also explicitly acknowledging geographic proximity‐based spatial dependencies in these patterns. At a methodological level, the paper focuses on specifying and estimating a spatial MDCP model that allows the dependent variable to exist in multiple discrete states with an intensity associated with each discrete state. The formulation also accommodates spatial dependencies, as well as spatial heterogeneity and heteroskedasticity, in the dependent variable, and should be applicable in a wide variety of fields where social and spatial dependencies between decision agents (or observation units) lead to spillover effects in multiple discrete‐continuous choices (or states). A simulation exercise is undertaken to evaluate the ability of the proposed maximum approximate composite marginal likelihood (MACML) approach to recover parameters from a cross‐sectional spatial MDCP model. The results show that the MACML approach does well in recovering parameters. An empirical demonstration of the approach is undertaken using the city of Austin parcel level land use data.  相似文献

The World Health Organization endorses the study of diseases from the perspective of the Determinants of Health (DH), that is, the circumstances in which people are born and raised, the environment in which they grow up and age and their lifestyle. The aim of this study is to analyze the spatial behavior of the prevalence of asthma in Aragon, a Mediterranean region in Spain, under the DH approach. The methodological process entailed building a spatial database collating asthma prevalence as dependent variable, and lifestyle, socioeconomic, and climate indicators as explanatory factors, and then evaluating the spatial variability of the relationships by combining the Principal Component Analysis (PCA), Multiscale Geographically Weighted Regression (MGWR) models and cartographic design techniques. MGWR evidenced spatially varying relationships operating at different scales. Lifestyles seem closely tied to the prevalence of asthma in most of the study area while urban functionality and local climate patterns seem to boost prevalence rates in some specific enclaves. Consequently, the social and environmental conditions that characterize the study area translate into several DH scenarios modulating the spatial distribution of asthma. This differential DH behavior detected by local regression models is relevant to guiding and refining public health decision-making.  相似文献

There is limited available data on the environmental context of the arrival of the first anatomically modern humans (AMH) in North Africa, and subsequent Paleolithic and Neolithic occupations within this region. Microvertebrates such as rodents, shrews, amphibians, and squamates are known to be good indicators of climate and landscape changes. They also represent continental paleoecological records that can be directly related to human occupations. Moreover, faunas and humans have been subjected to several dispersal waves through similar routes, and some rodents may present anthropophilous behavior. Therefore, by understanding the dispersal pattern and pathways of these microvertebrates, it is possible to propose scenarios for human dispersal events. In this study we took the rich microfaunal assemblages from the Témara region, Atlantic Morocco (El Harhoura 2 and El Mnasra Caves), and placed them within a broader synthesis, in order to highlight the role of microvertebrates in providing a better understanding of the human-environment relationship during the Late Quaternary in North Africa.  相似文献

In this paper we consider a crucial issue for survey archaeology: how we identify and make sense of the heterogeneous and often inter-dependent behaviours and processes responsible for apparent archaeological patterns across the landscape. We apply two spatial statistical tools, kriging and geographically weighted regression, to develop a model that addresses the spatial heterogeneity and spatial nonstationarity present in the pottery distributions identified by our intensive survey of the Greek island of Antikythera. Our modelling results highlight a clear spatial structure underlying different scales of pottery density as well as locally varying relationships between pottery densities and several environmental variables. This allows us to develop further testable hypotheses about long-term settlement and land-use patterns on Antikythera, including more explicit models of community organisation, and of the relationship between the island's geomorphological structure and its history of past human activity.  相似文献

It has been speculated that deterministic chaos may be responsible for the spatial complexity commonly observed in biophysical landscapes. However, deterministic chaos is a temporally defined concept and has been rigorously investigated only in the temporal domain. It is shown here, using a simple hillslope regolith cover model as an example, that temporal chaos in the presence of even minor spatial anisotropy will result in a spatially chaotic pattern. It is also shown that behavior of spatially chaotic landscape systems can be deduced, at least in theory, from spatial patterns of a single landscape component or variable. Because stochastic complexity is likely to exist in landscapes in addition to any deterministic complexity, detecting and analyzing chaotic behavior in landscapes is difficult. Progress in efforts to examine chaos in the spatial domain and to isolate deterministic and stochastic complexity may be the key to developing a theory of landscape evolution that can reconcile the simultaneous presence of apparently random, irregular variability and orderly, regular patterns.  相似文献

Using a mixed-methods approach, including qualitative, quantitative and Geographic Information Science methods, we assessed the primary school landscape around a protected area in Western Uganda. Data from a household survey, interviews and standardized school examinations were mapped to visualize spatial patterns in enrolment and academic achievement. We found children on average were starting school at age nine, but started to dropout as early as age 14; especially orphaned boys. Twenty of 36 schools demonstrated improving examination results from 2004 to 2013, although in one district improvements were lacking. Girls traditionally perform poorer than boys on exams in Uganda, but we found girls’ exam scores were catching-up. Support from one non-governmental organization with a long-term local presence was improving academic achievement. The use of Geographic Information Science provided spatially explicit recommendations to guide local policy actions for primary school education.  相似文献

This study presents a behavioral analysis of Middle and Upper Paleolithic lithic assemblages from 14 sites located in the southern Carpathian Mountains. Using a whole assemblage behavioral indicator, we show that the hominins that manufactured those stone tools do not appear to have differed in terms of the flexibility of the mobility strategies they employed to exploit their landscapes. Rather than biological change, we argue that large-scale climate changes are likely more important drivers of behavioral changes during the Late Pleistocene of the region, including during the Middle–Upper Paleolithic transition. These results agree well with the results of studies having employed this methodology in other regions, suggesting that this is a generalized feature of the transition across Eurasia. Recasting the transition as a mainly ecological rather than purely biocultural process allows us to generate new perspectives from which to approach the question of behavioral change during the Late Pleistocene, and ultimately suggests that the process referred to as the ‘Middle–Upper Paleolithic transition’ is essentially a brief segment of a much more extensive process driven by prehistoric human–environment interactions that would culminate in the highly logistical mobility strategies documented throughout the continent at the Last Glacial Maximum.  相似文献

Neanderthal settlement patterns in Crimea: A landscape approach   总被引:1,自引:1,他引:0  
Traditional settlement pattern analysis involves classifying sites within a region using previously established functional categories. Faunal and lithic data are frequently combined as archaeological indicators of site function. The results are interpreted in terms of a settlement system from which inferences about mobility patterns and social organization are drawn. The previously published site of Karabi Tamchin is used here as a spring-point for a discussion of the problems inherent with established site typologies and some of the settlement models that have been proposed in the past. The rich Middle Paleolithic archaeological record of Crimea is used to demonstrate the usefulness of the landscape approach as a means of supplementing existing information about Middle Paleolithic settlement patterns.  相似文献

This is a critical review of regional settlement pattern archaeology published in the last decade. The regional approach proves to be highly productive of new ideas and lasting results. Cultural resource/heritage databases are increasingly important. Notable advances have been made in regional studies of Paleolithic and Holocene foragers, the reciprocal relations between Neolithic communities and their regional societies, and in understanding states and empires. There are new research potentials in comparisons, macroregional analysis, long-term change, and alternative pathways. Research designs should specify systematic coverage at the regional scale and carry out spatial analysis in which social groups are the primary focus.  相似文献

During the last glacial maximum, the west European modern humans adapted to adverse conditions and their populations subsisted exploiting the natural resources available. Fish were always present as a source of animal protein, although their importance in the human diet and their contribution to the expansion of humans has not been fully explored. Based on the compilation of zooarchaeological evidences from north Spanish sites we have discovered a constant pattern of exploitation of freshwater fish (Salmonids) with high incidence in the human diet during the Upper Paleolithic. Shifts in the exploitation of marine resources can be explained by climate-related geographical changes. The characteristics of salmonids that make them target species for supporting human survival in adverse climate periods are identified and discussed.  相似文献

The timing and behavioral markers of the Upper Paleolithic in different parts of the world are of great importance to research on modern human dispersals. The pattern of behavioral developments in the Upper Paleolithic in northern China differs in important ways from the patterns observed in West Eurasia, Africa, and South Asia. Shuidonggou (SDG), a cluster of Paleolithic sites in northern China, contains several of the most important Upper Paleolithic sites in the region. Various localities yield evidence of three major cultural components dated by 14C, uranium-series, and optically stimulated luminescence (OSL) methods to between roughly 46 ka and 10 ka. The oldest component, blade assemblages with western Eurasian early Upper Paleolithic characteristics, appears to be intrusive from Siberia and/or Mongolia, beginning at least 41 ka (e.g., SDG 1 and SDG 9). Advanced core and flake assemblages may mark the appearance of an indigenous Late Paleolithic of North China beginning at around 33 ka (e.g., SDG 2 and SDG 8). Finally, around 10.5 ka, microblade technology arrived in the area (SDG 12), although we are not sure of its origins at present. Other typical Upper Paleolithic cultural remains, such as bone tools and body decorations, have been found at various localities in the SDG area as well (e.g., ostrich eggshell beads from SDG 2, 7, and 8). Information from this cluster of occupations increases our understanding of cultural variability, adaptation, and demographic dynamics of modern humans in Late Pleistocene northern Asia.

Abstract

This article presents a novel geospatial approach to reconstructing and analyzing environmental change over extensive spatial and temporal scales, even in systems such as rivers and streams that are comparatively difficult to digitize. We used a drawing tablet and stylus to digitize features found on historical Army Corps maps across the spatially extensive landscape of the Lower Wabash River’s riparian zone, in Indiana and Illinois, USA. The methodology allows for an efficient reconstruction of sinuous and irregular environmental features, such as sloughs, and demonstrates the utility of digitizing historical maps to understand the evolution of surface water quantity and location across a landscape. We then compared these historical data to contemporary environmental datasets for the same study area to understand what changes have occurred over a 100?year period. This reveals that the hydroscape of the Lower Wabash River has been significantly altered by past human activity, notably through the reduction of swamps, wetlands, and sandbars, and the increase in drainage ditches and overall stream area. Notably, many of these historical alterations are not captured within current environmental datasets.  相似文献

The influence of relief, as well as other environmental features such as soils or the hydrological regime, on prehistoric settlement patterns is commonly accepted. Settlement patterns and preferences changed over time in different areas, so it is difficult to formulate general rules of human behaviour throughout history. In lowland areas of the temperate zone, which lack radical relief changes and have widespread access to water resources, specific settlement preferences and significant changes in these preferences are difficult to interpret.New methods developed to address the problem of the settlement transformations as a result of prehistoric settlement and economic processes using multivariate statistics have been adapted for the middle part of the Great Poland Lowland. In this region, data from the Polish Archaeological Record Project database have been used.Models of the dependence between geomorphological features and settlement intensity form the basis for estimating changes in prehistoric settlements. The degree of preference (or avoidance) is a nonparametric function of the number of archaeological sites observed in the area relative to the number of sites expected from a completely random pattern. The most crucial factors for settlement are distance to plateau edges, distance to water bodies, and the wetness index. The results show that the entire investigated area is more or less suitable for settlement, but the most occupied terrains are the areas near plateau edges.  相似文献
