Silva et saltus en Gaule romaine : dynamique et gestion des forêts et des zones rurales marginales : actes du VIIe Colloque AGER, Rennes, 27-28 octobre 2004( )

1 edition published in 2020 in French and held by 5 WorldCat member libraries worldwide

Cet ouvrage rassemble les actes du colloque organisé par l'association d'étude du monde rural gallo-romain AGER et l'UMR 6566 Centre de Recherche en Archéologie, Archéosciences, Histoire, CNRS-université Rennes I, à Rennes, les 27 et 28 octobre 2004, à l'initiative de Vincent Bernard, chercheur CNRS. La thématique du colloque touche à des terrains et à des formes d'occupation du sol considérés, déjà dans l'Antiquité, comme marginales à l'espace cultivé (ager) mais dont les ressources participent à l'équilibre du système agropastoral illustré par la trilogie canonique ager, silva, saltus, l'espace cultivé, la forêt et la friche, c'est-à-dire l'espace cultivé laissé en repos. L'ouvrage issu de ce colloque est d'autant plus attendu que les manifestations scientifiques qui se sont tenues depuis en traitant de ce sujet n'ont pas été forcément centrées sur la Gaule romaine et n'ont pas pris en compte toutes les zones rurales marginales étudiées ici. Le colloque de Rennes est un colloque d'archéologues, où se croisent les données des sciences du paléo-environnement, relatives à la paléobotanique et à la paléofaune, les données archéologiques relatives à l'habitat et aux activités agro-pastorales et artisanales et les données historiques livrées par les textes, l'épigraphie, l'iconographie, etc. L'ouvrage regroupe dix-neuf contributions structurées en quatre parties thématiques : 1°) Marais et zones humides, 2°) Du Massif armoricain à la haute montagne, 3°) L'exploitation de la forêt et 4°) De l'importance du couvert forestier
Tree rings reveal globally coherent signature of cosmogenic radiocarbon events in 774 and 993 CE by Ulf Büntgen( )

2 editions published in 2018 in English and held by 5 WorldCat member libraries worldwide

Abstract: Though tree-ring chronologies are annually resolved, their dating has never been independently validated at the global scale. Moreover, it is unknown if atmospheric radiocarbon enrichment events of cosmogenic origin leave spatiotemporally consistent fingerprints. Here we measure the 14C content in 484 individual tree rings formed in the periods 770-780 and 990-1000 CE. Distinct 14C excursions starting in the boreal summer of 774 and the boreal spring of 993 ensure the precise dating of 44 tree-ring records from five continents. We also identify a meridional decline of 11-year mean atmospheric radiocarbon concentrations across both hemispheres. Corroborated by historical eye-witness accounts of red auroras, our results suggest a global exposure to strong solar proton radiation. To improve understanding of the return frequency and intensity of past cosmic events, which is particularly important for assessing the potential threat of space weather on our society, further annually resolved 14C measurements are needed
A multidisciplinary drought catalogue for southwestern Germany dating back to 1801 by Mathilde Erfurt( )

1 edition published in 2020 in English and held by 3 WorldCat member libraries worldwide

Abstract: Droughts are multidimensional hazards that can lead to substantial environmental and societal impacts. To understand causes and impacts, multiple perspectives need to be considered. Many studies have identified past drought events and investigated drought propagation from meteorological droughts via soil moisture to hydrological droughts, and some studies have included the impacts of these different types of drought. However, it is not certain whether the increased frequency and severity of drought events in the past decade is unprecedented in recent history. Therefore, we analyze different droughts and their impacts in a regional context using a multidisciplinary approach. We compile a comprehensive and long-term dataset to investigate possible temporal patterns in drought occurrence and place recent drought events into a historical context. We assembled a dataset of drought indices and recorded impacts over the last 218 years in southwestern Germany. Meteorological and river-flow indices were used to assess the natural drought dynamics. In addition, tree-ring data and recorded impacts were utilized to investigate drought events from an ecological and social perspective. Since 1801, 20 extreme droughts have been identified as common extreme events when applying the different indices. All events were associated with societal impacts. Our multi-dataset approach provides insights into similarities but also the unique aspects of different drought indices
Radiocarbon offsets and old world chronology as relevant to Mesopotamia, Egypt, Anatolia and Thera (Santorini) by Sturt W Manning( )

1 edition published in 2020 in English and held by 3 WorldCat member libraries worldwide

Abstract: The new IntCal20 radiocarbon record continues decades of successful practice by employing one calibration curve as an approximation for different regions across the hemisphere. Here we investigate three radiocarbon time-series of archaeological and historical importance from the Mediterranean-Anatolian region, which indicate, or may include, offsets from IntCal20 (~0-22 14C years). While modest, these differences are critical for our precise understanding of historical and environmental events across the Mediterranean Basin and Near East. Offsets towards older radiocarbon ages in Mediterranean-Anatolian wood can be explained by a divergence between high-resolution radiocarbon dates from the recent generation of accelerator mass spectrometry (AMS) versus dates from previous technologies, such as low-level gas proportional counting (LLGPC) and liquid scintillation spectrometry (LSS). However, another reason is likely differing growing season lengths and timings, which would affect the seasonal cycle of atmospheric radiocarbon concentrations recorded in different geographic zones. Understanding and correcting these offsets is key to the well-defined calendar placement of a Middle Bronze Age tree-ring chronology. This in turn resolves long-standing debate over Mesopotamian chronology in the earlier second millennium BCE. Last but not least, accurate dating is needed for any further assessment of the societal and environmental impact of the Thera/Santorini volcanic eruption
Dendrochronologische Untersuchungen an Holzfunden vom Neumarkt in Dresden by Willy Tegel( )

2 editions published in 2008 in German and held by 3 WorldCat member libraries worldwide

Zusammenfassung: Dendrochronologische Untersuchungen archäologischer Holzfunde vom Neumarkt in Dresden lieferten präzise absolute Zeitmarken für die frühe Stadtgeschichte von Dresden. Daneben sind die neu ermittelten Jahrringfolgen ein wichtiger Bestandteil für eine regionale sächsische Referenzchronologie, die sich im Aufbau befindet. Sollten sich die für die dendrochronologische Untersuchung der Holzproben von Dresden/Neumarkt herangezogenen anderen lokalen und regionalen Referenzchronologien durch die Einarbeitung neuen Untersuchungsmaterials verbessern, könnten auch noch bisher nicht datierbare Dresdner Jahrringserien Datierungsergebnisse liefern. Für eine Abschätzung historischen Bauholzbedarfs, der Waldbetriebsformen und der Herkunft möglicherweise geflößten Bauholzes sind noch viele weitere Untersuchungsreihen erforderlich. Mit der Ausgrabung und umfassenden dendrochronologischen Auswertung weiterer Holzbefunde ließen sich die Erkenntnisse zur Waldwirtschaft in Sachsen im Umbruch zwischen Mittelalter und Früher Neuzeit weiter vertiefen
Old world megadroughts and pluvials during the common era by E. R Cook( )

1 edition published in 2015 in English and held by 3 WorldCat member libraries worldwide

Abstract: Climate model projections suggest widespread drying in the Mediterranean Basin and wetting in Fennoscandia in the coming decades largely as a consequence of greenhouse gas forcing of climate. To place these and other "Old World" climate projections into historical perspective based on more complete estimates of natural hydroclimatic variability, we have developed the "Old World Drought Atlas" (OWDA), a set of year-to-year maps of tree-ring reconstructed summer wetness and dryness over Europe and the Mediterranean Basin during the Common Era. The OWDA matches historical accounts of severe drought and wetness with a spatial completeness not previously available. In addition, megadroughts reconstructed over north-central Europe in the 11th and mid-15th centuries reinforce other evidence from North America and Asia that droughts were more severe, extensive, and prolonged over Northern Hemisphere land areas before the 20th century, with an inadequate understanding of their causes. The OWDA provides new data to determine the causes of Old World drought and wetness and attribute past climate variability to forced and/or internal variability
Higher groundwater levels in western Europe characterize warm periods in the common era by Willy Tegel( )

1 edition published in 2020 in English and held by 3 WorldCat member libraries worldwide

Abstract: Hydroclimate, the interplay of moisture supply and evaporative demand, is essential for ecological and agricultural systems. The understanding of long-term hydroclimate changes is, however, limited because instrumental measurements are inadequate in length to capture the full range of precipitation and temperature variability and by the uneven distribution of high-resolution proxy records in space and time. Here, we present a tree-ring-based reconstruction of interannual to centennial-scale groundwater level (GWL) fluctuations for south-western Germany and north-eastern France. Continuously covering the period of 265-2017 CE, our new record from the Upper Rhine Valley shows that the warm periods during late Roman, medieval and recent times were characterized by higher GWLs. Lower GWLs were found during the cold periods of the Late Antique Little Ice Age (LALIA; 536 to ~ 660 CE) and the Little Ice Age (LIA; between medieval and recent warming). The reconstructed GWL fluctuations are in agreement with multidecadal North Atlantic climate variability derived from independent proxies. Warm and wet hydroclimate conditions are found during warm states of the Atlantic Ocean and positive phases of the North Atlantic Oscillation on decadal scales
Tree rings reveal signs of Europe's sustainable forest management long before the first historical evidence by Bernhard Muigg( )

1 edition published in 2020 in English and held by 3 WorldCat member libraries worldwide

Abstract: To satisfy the increasing demand for wood in central Europe during medieval times, a new system of forest management was developed, one far superior to simple coppicing. The adoption of a sophisticated, Coppice-with-Standards (CWS) management practice created a two-storey forest structure that could provide fuelwood as well as construction timber. Here we present a dendrochronological study of actively managed CWS forests in northern Bavaria to detect the radial growth response to cyclical understorey harvesting in overstorey oaks (<jats:italic>Quercus</jats:italic> sp.), so-called <jats:italic>standards</jats:italic>. All modern <jats:italic>standards</jats:italic> exhibit rapid growth releases every circa 30 years, most likely caused by regular understorey management. We further analyse tree-ring width patterns in 2120 oak timbers from historical buildings and archaeological excavations in southern Germany and north-eastern France, dating between 300 and 2015 CE, and succeeded in identifying CWS growth patterns throughout the medieval period. Several potential CWS <jats:italic>standards</jats:italic> even date to the first millennium CE, suggesting CWS management has been in practice long before its first mention in historical documents. Our dendrochronological approach should be expanded routinely to indentify the signature of past forest management practices in archaeological and historical oak wood

Dendrochronological evidence for long-distance timber trading in the Roman Empire by Mauro Bernabei( )

1 edition published in 2019 in English and held by 2 WorldCat member libraries worldwide

Abstract: An important question for our understanding of Roman history is how the Empire's economy was structured, and how long-distance trading within and between its provinces was organised and achieved. Moreover, it is still unclear whether large construction timbers, for use in Italy, came from the widespread temperate forests north of the Alps and were then transported to the sparsely-wooded Mediterranean region in the south. Here, we present dendrochronological results from the archaeological excavation of an expensively decorated portico in the centre of Rome. The oak trees (Quercus sp.), providing twenty-four well-preserved planks in waterlogged ground, had been felled between 40 and 60 CE in the Jura Mountains of north-eastern France. It is most likely that the wood was transported to the Eternal City on the Saône and Rhône rivers and then across the Mediterranean Sea. This rare dendrochronological evidence from the capital of the Roman Empire gives fresh impetus to the ongoing debate on the likelihood of transporting timber over long distances within and between Roman provinces. This study reconstructs the administrative and logistic efforts required to transport high-quality construction timber from central Europe to Rome. It also highlights an advanced network of trade, and emphasises the enormous value of oak wood in Roman times
