The Shaw Creek Flats and nearby middle Tanana river, in central Alaska, constitute one of the areas in the Americas with the densest known distribution of Late Glacial (about 14,500–11,700 cal. B.P.) archaeological sites. Local high rates of sediment deposition and low post-depositional disturbance allow for the interpretation of the function of archaeological occupations within larger economic and mobility strategies. Residential sites used over the long term seem to be located near critical but immovable resources such as clear water and vegetation. The spatial association of artifacts and faunal remains at other sites in the Flats suggest that they were specialized, short-lived locations dedicated to a single or few activities. For instance, the site of Swan Point Cultural Zone 4b is interpreted as a workshop related to the production of composite tools, particularly on mammoth ivory, and the site of Keystone Dune is interpreted as a camp related to wapiti (Cervus elaphus) hunting. These task-specific sites and others were probably used as part of a predominantly logistical mobility and economy strategy, which maximized efficiency in harvesting and processing resources that were distributed heterogeneously on the landscape.  相似文献

This article reports energy balance measurements which were made over a forest and a clear-cut site in the summer of 1985, and over the forest in 1987 at the Petawawa National Forestry institute (PNFI), Chalk River, Ontario. Evapotranspiration was evaluated by the Bowen ratio/energy balance method using a model of the Reversing Temperature Difference Measurement System (RTDMS) at each site in each year. The evapotranspiration regimes of the forest and clear-cut sites are interpreted within the resistance framework of the Penman-Monteith combination model. The behaviour of the Priestley and Taylor (1972) α term and the McNaughton and Jarvis (1983) Ω factor are discussed for both sites. The summer of 1987 was exceptionally dry and thus provided an opportunity to examine the forest's evapotranspiration regime under severe water stress. The soil moisture conditions in 1987 are in marked contrast to those in 7985, a wetter year. Dans cette communication, on fait état des mesures du bilan énergétique prises, à l'été 1985, au-dessus d'une région forestière et d'une région de terrain déblayé de sa futaie et, en 7987, au-dessus de la même région foresitière à l'lnstitut Forestier National de Petawawa, à Chalk River, Ontario. Avec la méthode du rapport de Bowen/bilan énergétique, on a déterminé l'évapotranspiration en utilisant un dispositif de mesure de la différence de température à renversement dans chaque région pour chacune des années. On interprète les régimes de I'évapotranspiration de la région forestière et de la région de terrain déblayé de la futaie dans le cadre de la résistance du modele combine de Penman et Monteith. On discute la tenue du terme α de Priestley et Taylor (1972) et du factor Ω de McNaughton et iarvis (1983) pour toutes les régions. Le temps en été 1987 était exceptionnelle-ment sec, favorisant I'examen d'un régime d'évapotranspiration sous des conditions de pénurie deau. Les conditions de sécheresse du sol font contraste avec celles de I'an 1985 qui étaient plus humides.  相似文献

The habitat and habit of Australia's first recorded Tertiary marsupial species, Wynyardia bassiana, found some 130 years ago at Wynyard on the northwestern coast of Tasmania, remain enigmatic (Aplin 1987, Aplin &; Rich 1990). Fossil pollen and spores preserved in a rafted clast of estuarine silts from the same sequence of earliest Miocene marine sandstones as the skeletal remains indicate the local vegetation was Nothofagus-gymnosperm evergreen rainforest, probably with a cryptogam-rich rather than woody subcanopy stratum. Comparisons with present-day Nothofagus rainforests suggest that, although the subcanopy would have been sufficiently open to allow the passage of a large ground-dwelling herbivorous marsupial, limited food resources are more consistent with Wynyardia being a generalist arboreal herbivore.  相似文献

A total of 453 bones (294 of galliform and 159 of gruiform birds) from 28 archaeological sites are considered here, 34 per cent of the total ornithoarchaeological wild bird finds collected in Bulgaria so far. They cover a period from the Early Neolithic to the Middle Ages. Eleven species (six galliform and five gruiform), 87.5 and 45.5 per cent, respectively, of the Holocene avifauna of both orders, have been identified. One species, Tetrao tetrix, has totally disappeared and three others, Grus grus, Otis tarda and O. tetrax, now breed beyond the borders of Bulgaria and the Balkans. Some of the sites of the large gamefowl species indicate their wider distribution in the past. Phasianus colchicus is present as early as the Eneolithic period. The wild galliform and gruiform species were important as a source of meat for the local population up to the Middle Ages, in spite of widespread breeding of domestic poultry. © 1997 John Wiley & Sons, Ltd.  相似文献

Numerous anthropogenic stressors have impacted the region surrounding Sudbury, Ontario, leading to pronounced vegetation and landscape change. Few long‐term records exist to understand the nature or timing of this change. We use pollen analysis from radiometrically dated sediments of Clearwater Lake to compare pre‐ and post‐settlement vegetation. Beginning ~1850 CE, the record shows major shifts in forest composition, coincident with settlement and the beginnings of lumbering. These changes are unprecedented for the past ~5000 years, and consist of increases in diversity and abundance of deciduous tree taxa and herbaceous disturbance indicators. While evidence of mining appears as early as 1900 CE, little effect is seen in the pollen record until ~1930 CE, when sedimentation rates increased and acidification of the lake also began. At this time, further increases in palynological disturbance indicators and minimum sediment organic matter levels indicate the period of maximum vegetation loss. As a result of reduced emissions since the 1970s, water quality began to improve in Clearwater Lake and there are some decreases in the abundances of shade‐intolerant disturbance indicators in the pollen record. However, the fact that the pollen assemblages do not resemble those prior to 1850 suggests lasting vegetation changes.  相似文献

Grotta Romanelli is one of the most important sites of the Italian palaeolithic. It contains a lithic industry from the Final Epigravettian, examples of rock and mobiliary art and numerous bone remains, among which were abundant remains of birds. Approximately 32 000 bird bones from over 3650 individuals and 109 species were identified. The most common species were bustards, Otis tetrax and O. tarda, and three species of goose, Anser fabalis, A. albifrons and Branta bernicla. Traces of butchering and burning were evident on numerous bones. The nature and location of the cut marks and burning is described here. The analysis has involved mostly the hind limbs and the shoulder girdle where traces are most numerous. The cut marks reflect a codified sequence of actions of disarticulation and dismemberment. © 1997 John Wiley & Sons, Ltd.  相似文献

Abstract

This paper presents the results of species diversity and dendrological analyses of archaeological charcoal excavated from medieval and early modern iron production sites in Bilsdale, and at Rievaulx in the neighbouring valley of Ryedale, North Yorkshire, UK. Standard methods of quantification are used to assess species diversity, sampling sufficiency and taxa presence. The assessment of dendrological features provides additional evidence for growth trends and cutting cycles analogous with cyclical woodland management, as well as environmental and growing conditions. Analysis of archaeological charcoal from four medieval bloomery furnace sites in Bilsdale, and from the site of the hammersmithy and blast furnace at the early modern iron works at Rievaulx, provide comparable data-sets which indicate a change in cutting practise and dominant species selection for industrial fuelwood occurred between the 12th- and mid-16th centuries AD. Results show that dominant species presence changed from an admixture of predominantly birch (Betula sp.) and hazel (Corylus avellana) sourced from small calibre branchwood and stemwood used in the medieval bloomery furnaces, to a dominant oak (Quercus sp.) presence from standard sources used at the Rievaulx iron works by the mid-16th century. Whilst it is uncertain whether this change in dominant species composition and the source of industrial fuelwood is related to changes in local availability, or the result of the technological transition to blast furnace processing which occurred at this time, estate records reveal a woodland management campaign was instigated to supply and maintain fuelwood supplies to the iron works at Rievaulx which coincides with the introduction of Tudor arboricultural legislation in the 1540s.  相似文献

Prehistoric land use and social activity in West New Britain, PNG, are well documented, although the landscapes – largely shaped by catastrophic volcanic eruptions – in which these took place, and the relationships people had with these landscapes, are poorly understood. We define the evolving landscape at Numundo, from prior to the Witori-Kimbe 2 eruption (W-K2, ca. 3600 BP) to after the Witori-Kimbe 4 eruption (W-K4, ca. 1400 BP), using fossil phytolith and coral evidence at eight archaeological sites to provide environmental evidence of the human responses to periodic catastrophic events. From ca. 5900 to 3600 BP, all the sites were coastal and disturbed. Early disturbance reflected natural forest recovery after W-K1 (ca. 5900 BP), whereas the later landscape was largely shaped by human activity. In contrast, forest regrowth was limited after W-K2 and open environments typical of human activity with a mosaic of regenerating, disturbed and managed vegetation, persisted until W-K3. Environmental recovery from W-K3 and W-K4 (ca. 1700 BP and ca. 1400 BP) differed completely, reflecting severity of the volcanism and the short time between eruptions. The landscape after W-K3 was largely a naturally recovering landscape, in contrast to effective vegetation recovery and significant human exploitation of the landscape – again a mosaic of regenerating, disturbed and managed vegetation – after W-K4. The social history is one in which people evolved increasingly flexible land-use practices, enabling them to re-settle this periodically disrupted landscape, and to take advantage of an increasingly broad range of habitats suitable for cultivation. The human response to this highly dynamic landscape represents a close relationship between social and natural processes, as people became increasingly better at re-settling an unpredictably disrupted landscape; both the social and environmental processes within this landscape become equally influential and instrumental in shaping the effects of the other.  相似文献

Since 1955 the NSW Department of Water Resources has undertaken extensive river training works on many NSW streams. In the Hunter Valley alone over $23 million have been spent and more than 850 km of channel have been treated Published work suggests that river training works are usually undertaken in response to a pre-existing problem of river instability but can also induce adverse hydrogeomorphic effects. One of the treated streams, the Allyn River, had been supposedly degraded by the constructed works. It was alleged that vegetation clearing, channel excavations, alignment straightening and bank protection works had decreased roughness thus increasing velocity and flood frequency. As a result, what were thought to be relatively moderate floods were eroding the banks and destroying the floodplain. A critical evaluation of the available hydraulic, hydrologic and geomorphic data revealed that the river training works were a response to, rather than a cause of river instability.  相似文献

Abstract

At Doel, in the lower basin of the river Scheldt, excavations have revealed camp sites of the Swifterbant culture dating back to the second half of the fifth millennium BC. They document the transition period from the Late Mesolithic to the Early Neolithic in Sandy Flanders (NW Belgium). The sites were situated on the top of sandy ridges which were covered with an alluvial hardwood forest vegetation and surrounded by wetlands. Only burnt animal remains survived at the sites, illustrating (seasonal) fishing and hunting. In addition, botanical evidence indicates the herding of domestic mammals. The finds are of importance for the reconstruction of the chronological development of the food economy of the Swifterbant culture.  相似文献

A new methodology for estimating the age of death of horse, based on the degree of hypsondonty, has been established using the dental material of Equus mosbachensis, Equus cf. taubachensis, and Equus sp., which were hunted from the Mousterian levels of the Bau de l'Aubesier at Monieux (Vaucluse, France). Our model is based on a regression analysis of curvilinear type, and allows the precise determination of age classes intervals and the distribution of estimated ages, by systematically taking into account the standard deviation. These estimates were tested from all the paired teeth of horses belonging to the same individuals, from the sites of Bau de l'Aubesier and of Jaurens at Nespouls (Corrèze, France).The age structures of the horses of Bau de l'Aubesier were compared in the different levels of the sequence with their frequencies, survival rates, and mortality rates corresponding to as many curves as often used in population ecology and demographics. The different age classes of a present-day natural African population (Equus burchelli boehmi), the individuals having died accidentally in the National Park of Akagera (Rwanda) following a bush fire, provide an interesting comparative catastrophic model with regard to the population dynamics, and permit us to evaluate the impact of Neandertals on the Equidae fossils of Bau de l'Aubesier. Our assemblage clearly indicates in the lower layers, a systematic selection of adult horses, as opposed to the upper sequence where juveniles and adults dominate. Ecological factors, such as seasonal migratory phenomena and herd gathering, which characterise many large size species are also tackled and could explain the high proportion of adults in French Middle Palaeolithic sites where horses were preferentially hunted.  相似文献

Based on analyses of the ecological environments of the Neolithic sites along the Chan and Ba Rivers in the Xi’an area (Shaanxi Province, China), it was found that the characteristic factors of the sites had a very close relationship with the nearby river. The characteristic factors of Neolithic sites have been analysed and defined as mathematical parameters by statistical methods. A mathematical model of the human–land relationship between Neolithic sites and rivers has been established using the stepwise regression procedure REGRESS in SPSS®. The mathematical model is Y = 496.153 – 4.833X+ 113.692X3 + 725.097X5 – 27.683X3X4. It shows that the distance (Y) from a site to a river has a marked relationship with the site area (X1), the river flux (X3), the site location (X5) and river ratio drop (X4). The model shows that the relationship between the sites and the river is in accordance with the conclusions of archaeological research. The mathematical model not only offers theoretical guidance for the archaeological excavation of Neolithic sites in Xi’an, but also contributes to the archaeological environmental research of Xi’an Neolithic sites.   相似文献

Abstract

Results relating to the identification of macroscopic plant remains (leaves, fruits, seeds) discovered during the archaeological excavation of the Roman harbour of Pisa, in Tuscany, Italy are reported. The plant samples include the cultivated species Prunus spp., Corylus, Olea, Vicia, Juglans and the nemoral wild species Salix spp., Quercus spp., Fagus, Ulmus, Alnus. The remains of cultivated plants — fragments of fruits and seeds — were perhaps part of the boats' cargo or stores for the crew's meals. In the case of the wild taxa, the simultaneous presence of fruit and leaves, suggests that the remains recovered came from the forest vegetation bordering the area of excavation and the adjacent higher grounds, thus delineating a new vegetation landscape for the ager pisanus.  相似文献

Abstract

This is the second preliminary report of excavations and analyses of Opovo-Ugar Bajbuk, a Neolithic settlement of the Vin?a-Plo?nik culture located in the lower Tami? river valley, NE Yugoslavia. The Opovo Archaeological Project began in the summer of 1983; this report coversthe 1985–1987 field seasons. Work at Opovo has continued to reveal more about the unusual reliance placed by the site’s inhabitants on wild food resources, the apparent lack of long-term settlement occupation, and the social organization of production and consumption. An unexpected find of the 1987 season was a fragment of linen, the earliest direct evidence for textile production in European prehistory. Detailed examination of methods of house construction and house destruction—part of an effort to investigate the role of households at the site—led to the discovery of the first two-story dwelling ever encountered at a Vin?a site. The site of Opovo-Ugar Bajbuk is providing new light on previously unknown dimensions of variation within the Vin?a culture.  相似文献

About 4200 charcoal fragments have been identified from the fourth‐ to third‐millennium BC archaeological sites of Bat and Al‐Khashbah in order to gain an understanding of plant resources available at the sites. Acacia sp., Ziziphus sp., and Tamarix sp. were the main taxa identified at both sites and indicate a similar vegetation composition as today. Phoenix sp. (date palm) charcoal also has been found at both sites. Whereas the cultivation of date palm for the 2700–2300 BC layers from Bat was likely, given other circumstantial evidence (i.e. local cereal cultivation and floodwater irrigation), it is unclear whether date palm was cultivated at Al‐Khashbah. Especially for the older periods (3300–2700 BC) it is possible that nomadic pastoralists were exploiting and/or managing wild date palms. The find of Avicennia marina at Al‐Khashbah indicates long‐distance contacts with the coast.  相似文献

Fragmentation of bird bones in pellets and uneaten food remains of imperial eagles (Aquila heliaca) was studied. The degree of fragmentation was higher than that produced by owls and lower than that in gyrfalcons. There were significant differences between pellets and uneaten remains in the survival of bones and their fragmentation. © 1997 by John Wiley & Sons, Ltd. Int. J.

The remains of six species of geese are commonly recovered from archaeological sites in Britain dating from the Saxon and later periods. However, identification of this material to species level is hampered by a lack of morphological variation and a large overlap in size. To address this issue we obtained DNA sequence data for a section of the mitochondrial cytochrome b gene from modern samples of each species, and successfully identified several DNA markers for Branta species. No markers were found within the cytochrome b gene for the genus Anser. Ancient DNA techniques were then used to recover DNA from goose bones excavated from two archaeological sites. The DNA sequences enabled identification of Barnacle goose (Branta leucopsis) from one site and confirmed the presence of Anser species at another. © 1998 John Wiley & Sons, Ltd.  相似文献

Archaeological faunal assemblages can provide data valuable to modern conservation ecology. For example, while freshwater mussels (Bivalvia: Unionidae, Margaritiferidae) are common constituents in the archaeological record of North America, today they are one of the world’s most imperiled faunal groups. Efforts to aid habitat restoration, population growth, and species reintroduction can be informed by studies of prehistoric mussel assemblages. These data can provide a historical perspective, cataloging communities as they existed prior to extensive modern impacts, thus representing an ecological baseline to be compared with modern populations. This study focuses on two late prehistoric (ca. 300–600 AD) sites on the Yazoo River, where nearly 24,000 freshwater mussel valves were recovered. Though modern data are extremely limited for the river, analysis revealed it once supported a diverse mussel community containing numerous species currently considered rare, endangered, or extinct in Mississippi. In total, the combined shell assemblages yielded 23 new river records for the Yazoo River. One species in particular, Quadrula fragosa, represents the second such occurrence in Mississippi, and bolsters its candidate status as a new state record, as argued in a recent report from a neighbouring river in the Yazoo Basin.  相似文献

The potential use of existing radiometric data sets, previously collected for prospecting purposes, has very rarely been used as a variable predictor in wildlife habitat modelling. The utility of radiometric data for predicting vegetation community patterns and wildlife habitat was investigated in the Australian arid zone using the Burt Plain bioregion as a case study. Using spatial datasets and a Species Distribution Modelling Toolkit, arid zone vertebrate species were modelled with Generalised Linear Modelling (GLM) regression modelling techniques. These models were used to predict the probability of occurrence of a species at any given location, defined in terms of its environmental attributes. A statistical correlation between the radioactive elements uranium, thorium and potassium, and terrain aspect was found. No statistical correlations were established between the radioactive elements and vegetation patterns; although we suspect these exist at finer scales of mapping. Radiometric data were identified as explanatory variables in the habitat models of all of the 32 vertebrate species examined, and used as illustration in the development of probabilistic spatial predictions of three species (Red Kangaroo, Macropus rufus; Lesser Hairy‐footed Dunnart, Sminthopsis youngsoni; and Rabbit, Oryctolagus cuniculus) in the bioregion. Our analyses suggest that radiometric data sets involving the radioactive elements: (uranium, thorium, and potassium), and vegetation could be used as predictors of biodiversity patterns at the bioregional and landscape level. This is an important finding given the challenges posed in undertaking broad‐scale biological surveys in the arid zone of Australia.  相似文献
