Vivianite is a bluish mineral sometimes encountered in archaeological deposits. It is notable for its tendency to change color from white or grayish to blue on exposure to air. Vivianite requires specific conditions for its formation-sources of iron, phosphate, and water, as well as low levels of oxygen and sulfide. Microbial activity is also thought to play a part in vivianite formation. The majority of archaeological texts do not discuss vivianite to any great degree, preventing a more detailed interpretation of site conditions and features. Vivianite was found in 25 exhumed burials from the North Brisbane Burial Ground, Queensland, Australia. Research indicated that bone or tissue samples for DNA analysis are best taken from areas distant from vivianite encrustations and that presence of vivianite has implications for artifact conservation. Vivianite at the North Brisbane Burial Grounds helped protect some skeletal and dental elements, preserved the impressions of metal coffin lacing, and also corroborated the oral history of temporary waterlogging and acted as a measure of pollution levels across the site.

Evidence for the presence of storage pits described in Hittite texts by the Sumerogram "ÉSAG" is presented from Kaman-Kalehöyük, a multi-period tell site in central Turkey occupied during the second and first millennia BC. Small earthen pits matching the description of "ÉSAG" were part of the normal suite of domestic installations at the site throughout the period. Similar to pits seen across western Eurasia, they were probably used to store seed corn or seed for trade. Large earthen pits (>7m in diameter) were also present that matched the description of the "ÉSAG" form, and in some cases contained archaeological cereal remains. Evidence from Kaman shows "ÉSAG" were part of Anatolian life for at least 4,000 years and suggests that the term was generic for lined, earthen storage pits. The presence of so many small pits at Kaman-Kalehöyük showed that it was an agricultural production site for much of its existence. The appearance of the large pits, confined to the Hittite period, reflects centralised control of grain supply, probably by the Hittite Kingdom, and fits a pattern seen at other sites in the region during the second millennium BC. /// Hitit metinlerinde Sumerogram "ÉSAG" ile tanimlanan depo çukurlarinin varliğina dair kanit, Orta Anadolu'da M.Ö. İkinci ve Birinci binde iskan edilmiş çok dönemli bir yerleşim alani olan Kaman-Kalehöyük'ten taninmaktadir. Küçük toprak çukurlar "ÉSAG" in tanimlamasina uygun olarak bu dönem süresince normal ev düzeninin bir parçasi olarak karşimiza çikmiştir. Çukurlar, Bati Avrasya'daki benzer çukurlar gibi olasilikla ticaret maksadi ile misir tohumu ya da tohum muhafaza etmişlerdir. "ÉSAG" formunun tanimina uyan büyük toprak çukurlara (çapi 7m. den büyük) rağmen bunlarin tahil depolama ile ilgili bağlantilari tam olarak belirlenmemiştir. Kaman'daki delil, "ÉSAG" in en az 4,000 yildir Anadolu yaşaminin bir parçasi olduğunu ve bu sözcüğün sivanmiş toprak çukurlar için kullanildiğini işaret etmektedir. Kaman-Kalehöyük'te ele geçen birçok küçük çukur, yerleşimin varliğini sürdürdüǧü sürecin büyük bir bölümünde zirai üretim yapildiğini göstermektedir. Hitit Döneminde büyük çukurlarin ortaya çikmasi muhtemelen Hitit Kralliği tarafindan gerçekleştirilen tahil tedarikinin merkezi kontrolünü yansitmakta ve M.Ö. İkinci binde bu bölgedeki diğer yerleşim alanlarinda görülen şekle uymaktadir.

The discovery and interpretation of microscopic residues on stone artefacts is an expanding front within archaeological science, allowing reconstructions of the past use of specific tools. With notable exceptions, however, the field has seen little theoretical development, relying largely on a rationale in which either individual findings are widely generalized or the age of the site determines the importance of the results. Here an approach to residue interpretation is proposed that draws on notions of narrative, scale, action and agency as one means of expanding the theoretical scope and application of residue studies. It is suggested that the individual resonance of the findings of residue analyses with people in the present day can be used to provide a more nuanced understanding of past actions, which in turn allows both better integration and communication of those findings within and outside the archaeological comm unity, and begins to overcome the problems associated with the typically small sample sizes analysed in stone-tool residue studies.

Freshwater is extremely precious; but even more precious than freshwater is clean freshwater. From the time that 2/3 of our planet is covered in water, we have contaminated our globe with chemicals that have been used by industrial activities over the last century in a unprecedented way causing harm to humans and wildlife. We have to adopt a new scientific mindset in order to face this problem so to protect this important resource. The Water Framework Directive (European Parliament and the Council, 2000) is a milestone legislative document that transformed the way that water quality monitoring is undertaken across all Member States by introducing the Ecological and Chemical Status. A “good or higher” Ecological Status is expected to be achieved for all waterbodies in Europe by 2015. Yet, most of the European waterbodies, which are determined to be at risk, or of moderate to bad quality, further information will be required so that adequate remediation strategies can be implemented. To date, water quality evaluation is based on five biological components (phytoplankton, macrophytes and benthic algae, macroinvertebrates and fishes) and various hydromorphological and physicochemical elements. The evaluation of the chemical status is principally based on 33 priority substances and on 12 xenobiotics, considered as dangerous for the environment. This approach takes into account only a part of the numerous xenobiotics that can be present in surface waters and could not evidence all the possible causes of ecotoxicological stress that can act in a water section. The mixtures of toxic chemicals may constitute an ecological risk not predictable on the basis of the single component concentration. To improve water quality, sources of contamination and causes of ecological alterations need to be identified. On the other hand, the analysis of the community structure, which is the result of multiple processes, including hydrological constrains and physico-chemical stress, give back only a “photograph” of the actual status of a site without revealing causes and sources of the perturbation. A multidisciplinary approach, able to integrate the information obtained by different methods, such as community structure analysis and eco-genotoxicological studies, could help overcome some of the difficulties in properly identifying the different causes of stress in risk assessment. In synthesis, the river ecological status is the result of a combination of multiple pressures that, for management purposes and quality improvement, have to be disentangled from each other. To reduce actual uncertainty in risk assessment, methods that establish quantitative links between levels of contamination and community alterations are needed. The analysis of macrobenthic invertebrate community structure has been widely used to identify sites subjected to perturbation. Trait-based descriptors of community structure constitute a useful method in ecological risk assessment. The diagnostic capacity of freshwater biomonitoring could be improved by chronic sublethal toxicity testing of water and sediment samples. Requiring an exposure time that covers most of the species’ life cycle, chronic toxicity tests are able to reveal negative effects on life-history traits at contaminant concentrations well below the acute toxicity level. Furthermore, the responses of high-level endpoints (growth, fecundity, mortality) can be integrated in order to evaluate the impact on population’s dynamics, a highly relevant endpoint from the ecological point of view. To gain more accurate information about potential causes and consequences of environmental contamination, the evaluation of adverse effects at physiological, biochemical and genetic level is also needed. The use of different biomarkers and toxicity tests can give information about the sub-lethal and toxic load of environmental compartments. Biomarkers give essential information about the exposure to toxicants, such as endocrine disruptor compounds and genotoxic substances whose negative effects cannot be evidenced by using only high-level toxicological endpoints. The increasing presence of genotoxic pollutants in the environment has caused concern regarding the potential harmful effects of xenobiotics on human health, and interest on the development of new and more sensitive methods for the assessment of mutagenic and cancerogenic risk. Within the WFD, biomarkers and bioassays are regarded as important tools to gain lines of evidence for cause-effect relationship in ecological quality assessment. Despite the scientific community clearly addresses the advantages and necessity of an ecotoxicological approach within the ecological quality assessment, a recent review reports that, more than one decade after the publication of the WFD, only few studies have attempted to integrate ecological water status assessment and biological methods (namely biomarkers or bioassays). None of the fifteen reviewed studies included both biomarkers and bioassays. The integrated approach developed in this PhD Thesis comprises a set of laboratory bioassays (Daphnia magna acute and chronic toxicity tests, Comet Assay and FPG-Comet) newly-developed, modified tacking a cue from standardized existing protocols or applied for freshwater quality testing (ecotoxicological, genotoxicological and toxicogenomic assays), coupled with field investigations on macrobenthic community structures (SPEAR and EBI indexes). Together with the development of new bioassays with Daphnia magna, the feasibility of eco-genotoxicological testing of freshwater and sediment quality with Heterocypris incongruens was evaluated (Comet Assay and a protocol for chronic toxicity). However, the Comet Assay, although standardized, was not applied to freshwater samples due to the lack of sensitivity of this species observed after 24h of exposure to relatively high (and not environmentally relevant) concentrations of reference genotoxicants. Furthermore, this species demonstrated to be unsuitable also for chronic toxicity testing due to the difficult evaluation of fecundity as sub-lethal endpoint of exposure and complications due to its biology and behaviour. The study was applied to a pilot hydrographic sub-Basin, by selecting section subjected to different levels of anthropogenic pressure: this allowed us to establish the reference conditions, to select the most significant endpoints and to evaluate the coherence of the responses of the different lines of evidence (alteration of community structure, eco-genotoxicological responses, alteration of gene expression profiles) and, finally, the diagnostic capacity of the monitoring strategy. Significant correlations were found between the genotoxicological parameter Tail Intensity % (TI%) and macrobenthic community descriptors SPEAR (p<0.001) and EBI (p<0.05), between the genotoxicological parameter describing DNA oxidative stress (ΔTI%) and mean levels of nitrates (p<0.01) and between reproductive impairment (Failed Development % from D. magna chronic bioassays) and TI% (p<0.001) as well as EBI (p<0.001). While correlation among parameters demonstrates a general coherence in the response to increasing impacts, the concomitant ability of each single endpoint to be responsive to specific sources of stress is at the basis of the diagnostic capacity of the integrated approach as demonstrated by stations presenting a mismatch among the different lines of evidence. The chosen set of bioassays, as well as the selected endpoints, are not providing redundant indications on the water quality status but, on the contrary, are contributing with complementary pieces of information about the several stressors that insist simultaneously on a waterbody section providing this monitoring strategy with a solid diagnostic capacity. Our approach should provide opportunities for the integration of biological effects into monitoring programmes for surface water, especially in investigative monitoring. Moreover, it should provide a more realistic assessment of impact and exposure of aquatic organisms to contaminants. Finally this approach should provide an evaluation of drivers of change in biodiversity and its causalities on ecosystem function/services provision, that is the direct and indirect contributions to human well-being.

O desenvolvimento das novas tecnologias de comunicação e informação não representa apenas uma nova forma de transmitir conteúdos informacionais às pessoas. Ao se refletir nas novas possibilidades de atuação à distância, permitida pela mídia interativa on-line, percebese uma mudança significativa na postura comportamental das pessoas em suas interações nas relações sociais básicas. Há uma transformação ocorrendo no conceito de comunidade, visto que as novas e emergentes formas de comunicação, próprias do atual cenário tecnológico, passam a coabitar com as formas tradicionais de comunidade. Esta metamorfose seria produto de uma tentativa de agregação das práticas sociais realizadas nas comunidades reais dentro de um espaço virtual. Surgem assim as chamadas comunidades virtuais, que carregam consigo uma nova dinâmica de atuação a distância disjunta de contextos sociais imediatos. Através da metodologia de estudo de caso, buscou-se conhecer como as coabitações de formas tradicionais e emergent es de comunidades estão convivendo e interagindo. Além disso, procurou-se conhecer quais são os resultados obtidos das trocas informacionais e relacionais ocorridas no ciberespaço. A investigação se deu a partir do estudo de caso de um site da Igreja Adventista do Sétimo Dia, no qual foram utilizadas entrevistas, observação direta e observação participativa como fontes de evidência. Os resultados obtidos da investigação sugerem que o indivíduo corpóreo deseja viver dentro de uma nova ambiência regida pela fluidez digital, pois esta se apresenta como um meio no qual as trocas informacionais se dão de forma efetiva e responsiva, ao mesmo tempo em que relacionamentos sociais podem ser engendrados, confirmados e mantidos.(AU)

Archaeological fish otoliths have the potential to serve as proxies for both season of site occupation and palaeoclimate conditions. By sampling along the distinctive sub-annual seasonal bands of the otolith and completing a stable isotope (δ¹⁸O, δ¹³C) analysis, variations within the fish’s environment can be identified. Through the analysis of cod otoliths from two archaeological sites on Kiska Island, Gertrude Cove (KIS-010) and Witchcraft Point (KIS-005), this research evaluates a micromilling methodological approach to extracting climatic data from archaeological cod otoliths. In addition, δ¹⁸Ootolith data and radiocarbon dates frame a discussion of Pacific cod harvesting, site occupation, and changing climatic conditions on Kiska Island. To aid in the interpretation of the archaeological Pacific cod results, archaeological and modern Atlantic cod otoliths were also analyzed as a component of this study to develop. The Atlantic cod otoliths provided the methodological and interpretative framework for the study, and also served to assess the efficacy of this sampling strategy for archaeological materials and to add time-depth to existing datasets. The δ¹⁸Ootolith values successfully illustrate relative variation in ambient water temperature. The Pacific cod δ¹⁸O values demonstrate a weak seasonal signal identifiable up to year 3, followed by relatively stable values until year 6/7 when values continuously increase. Based on the δ¹⁸O values, the Pacific cod were exposed to the coldest water temperatures immediately prior to capture. The lack of a clear cycle of seasonal variation and the continued increase in values towards the otolith edge obscures the season of capture, and indicates that other behavioural, environmental, or methodological factors influenced the otolith δ¹⁸O values. It is suggested that Pacific cod would have been harvested throughout the year, and the presence of cod remains in Aleutian archaeological sites cannot be used as a reliable indicator of summer occupation. In addition, when the δ¹⁸O otolith values are integrated with radiocarbon dates and known climatic regimes, it is demonstrated that climatic conditions play an integral role in the pattern of occupation at Gertrude Cove. Initial site occupation coincides with the end of a neoglacial cooling period, and the most recent and continuous occupation coincides with the end of a localized warming period and the onset of the Little Ice Age (LIA).

La presente tesis doctoral se centra en el estudio del patrimonio geológico-minero del conjunto de labores mineras abandonadas situadas en la vertiente cántabra del Macizo Central de los Picos de Europa, al norte de España. El análisis llevado a cabo abarca desde la recopilación de la información histórica y bibliográfica, hasta el inventario y la valoración de los numerosos vestigios mineros aún presentes en la zona de estudio. Finalmente, se han realizado una serie de propuestas de puesta en valor y gestión del patrimonio minero, con el ánimo y objetivo final de contribuir a su conservación y a la integración socio cultural con el entorno. El hecho de que el área estudiada se sitúe dentro de un Parque Nacional, confiere a esta investigación, así como a las propuestas que de ella se derivan, unas peculiaridades que pueden no ser aplicables a otras zonas con diferente nivel de protección. No obstante, las metodologías propuestas, tanto en los estudios superficiales como en los subterráneos, así como en el modelo de ficha diseñado para el inventario, y los criterios establecidos para la valoración patrimonial pueden hacerse extensibles a cualquier investigación en otras comarcas mineras abandonadas. Las minas del Macizo Central de los Picos de Europa han estado en explotación de manera casi ininterrumpida desde 1856 hasta 1989, año en el que se cierra la principal mina, Las Mánforas. El legado de esta actividad es la presencia de numerosos vestigios geológico-mineros, que van desde infraestructuras para el transporte del mineral y para los trabajadores, edificios mineros, explotaciones y escombreras mineras, hasta un rico patrimonio mueble en forma de ejemplares de esfalerita (blenda acaramelada) que se encuentran en las principales colecciones mineralógicas del mundo, tanto privadas como públicas...
