Article
We compared fire episodes over the past 150 years reconstructed using charcoal particles retrieved from well-dated sediment deposits from two small lakes in the eastern Canadian boreal forest, with dendrochronological reconstructions of fire events from the corresponding watersheds. Fire scars and age structure of living trees highlighted three fir...

Fires have played an important role in creating and maintaining savannas over the centuries and are also one of the main natural disturbances in forests. The functional role of fires in savannas and forests can be investigated through examining sedimentary charcoal in order to reconstruct long-term fire history. However, the relationship between ch...

Severe windthrows often require salvage operations that can lead to increased costs. Given these extra costs, it is of paramount importance to make sure that wood degradation does not become so advanced that significant value loss is incurred. The rate at which wood deteriorates is a function of many factors, including species and climate. The stud...
Article
1. Macroscopic sedimentary charcoal and plant macroremains from two lakes, 50 km apart, in north-western Ontario, Canada, were analysed to investigate fire frequency and tree abundance in the central boreal forest. These records were used to examine the controls over the long-term fire regime, and vegetative dynamics associated with fire return int...
Article
The tragic fire of Notre-Dame Cathedral in Paris on April 15th 2019 has provided researchers with a wide variety of materials to study. The condition of the framework remains does not allow any reuse, which creates an unprecedented opportunity to study the charred pieces of the frame: about 10,000 for the highest estimates. But upstream from the wo...
Article
Pollen-based vegetation change has been inferred from sediments in Kalavan Red Lake. This small lake is placed in the beech-oak-hornbeam forest, about three kilometres away from archaeological remains. It has the potential to document the Holocene forest history and climate and human impacts on the Lesser Caucasus. However, this lake happens to be...

Les développements méthodologiques en anthracologie permettent actuellement d’obtenir des spectres de fréquences de taxons représentatifs des environnements passés, moyennant des conditions précises d’échantillonnage et de tamisage. Pourtant, d’autres informations sont disponibles dans les charbons de bois, en particulier ceux de taille pluricentim...
Article
Full-text available
We evaluated the skills of different palaeofire reconstruction techniques to reconstruct the fire history of a boreal landscape (Russian Karelia) affected by surface fires. The analysis of dated lacustrine sediments from two nearby lakes was compared with independent dendrochronological dating of fire scars, methods which have rarely been used in c...
Presentation
Depuis le début des années 2000, plusieurs études et projets cherchent à exploiter les informations de morphologie des cernes (courbure, largeur etc.) des charbons de bois retrouvés en contextes archéologiques afin de répondre à des questions liées aux durées d’occupation des sites, à l’interdatation des structures (habitations, fours), à la gestio...
Article
Full-text available
In many boreal regions of Russia the past natural variability of forest fire activity remains largely undocumented, preventing accurate assessment of the impact of current climate warming on forest ecosystem dynamics. This study aims to reconstruct the Holocene fire history of the northern Ural mountain foothills, in the Komi Republic, based on ana...
Article
Tree-ring studies, particularly those focusing on the δ13C isotopic signal, have become a reliable method to reconstruct past climatic and environmental conditions. Unfortunately, wood remains are notably absent from the very ancient archaeological record, due to degradability of plant tissue. For archaeological studies, the analysis of isotopic si...
Presentation
Au cours des dernières décennies, les études paléoenvironnementales sur le Pléistocène ont connu une accélération sans précédent grâce au développement d’approches pluridisciplinaires et holistiques intégrant l’ensemble des strates environnementales (biosphère, géosphère, hydrosphère, etc.), à la combinaison de nouvelles techniques de laboratoire e...
Presentation
Des études pionnières, combinant les méthodes classiques d’étude des charbons archéologiques avec des analyses isotopiques (δ13C), ont montré qu’il est possible d’apporter des informations inédites sur les paléo-environnements et les paléoclimats. Toutefois, ces méthodes émergentes ne sont pas encore applicables en routine. Notre étude porte à la f...

La compréhension des changements climatiques est un enjeu primordial, d’une part, si l’on veut appréhender la complexité de l’évolution des paysages et de leurs environnements forestiers, et d’autre part, si l’on veut mesurer leurs impacts sur l’histoire socio-technico-culturelle des sociétés passées et actuelles. Dans cette optique, les dernières...

Pollarding trees in agroforestry systems? Why and when? Implications in terms of woof production
Article
Full-text available
ABSTRACT: The intensity of cyclic larch budmoth ( Zeiraphera diniana GuenÈe; LBM) outbreaks across the European Alps has been reported to have weakened since the early 1980s. In addition to a warmer climate, changes in land-use cover over modern and historical times may have affected the LBM system. Here, we present tree-ring-based reconstructions...

Wildland fire is the most important disturbance in Mediterranean ecosystems characterized by endemic yearly drought. Fires act on both the diversity and structure of plant communities. Because Aleppo pine (Pinus halepensis) is closely associated with wildfire, the dynamics of its population could regulate the load of woody debris (WD) during early...

Background/Question/Methods Wildfire is the major naturally occurring disturbance for much of the boreal forest in North America, greatly influencing forest structure and function. Climate appears to be the main process triggering fire and local factors are seen to play a significant role in the spatial distribution of fire. In order to investiga...

L’aspect chronologique en anthracologie reste peu exploité. Ce projet a pour but de faire connaître l’anthraco-chronologie aux différents acteurs en lien avec l’archéologie, la dendrochronologie, l’anthracologie, etc. et d’échanger sur les besoins et les développements de ce nouveau champ d’application. The chronological aspect in anthracology remains little exploited. The aim of this project is to make anthraco-chronology known to the various actors involved in archaeology, dendrochronology, anthracology, etc. and to discuss the needs and developments in this new scope of application.
