A Regional Synthesis of Post-Glacial Fire History in the Eastern Cascades, Washington, Using Macroscopic Charcoal Analysis
… objective of this study was to determine if CharAnalysis, a statistical program developed to reconstruct fire history from macroscopic charcoal-based records, is appropriate for use with charcoal records from the eastern Cascades of Washington. The second major objective was to develop a regional …

Holocene environmental change and the vegetation community dynamics of the Kynsna forest : pollen and charcoal analysis of sediments from Groenvlei, Southern Cape, South Africa
… by radiocarbon means and subsampled for the analysis of fossil pollen and charcoal particles, environmental proxies used respectively to infer a vegetation and fire history for the region.

Interactions between human industry and woodland ecology in the South Pennines
… survey of case study sites was combined with charcoal analysis from excavated burning platforms, palynology of soil cores, tree ring analysis and ecological survey. This was set within a historical context, particularly focusing on the regional industries of iron, leather and textiles, in …

Aspects of the Flandrian vegetational history of south-west Scotland, with special reference to possible Mesolithic impact
… 000 - 5000 b. p. was investigated by pollen and charcoal analysis of small peat-filled basins and blanket peat near to the sites of lithics and in the context of subsequent vegetational history (from c. 5000 b. p.). Attention focused on upland sites by Loch Doon and Loch Dee. Upland areas by …

Understanding good ecological status: a palaeolimnological approach
… current study uses multiproxy palaeolimnological analysis of sediment cores to reconstruct the long-term (10² to 10³ years) nutrient status of Upper Talley and Llyn Pencarreg, two closely adjacent, moderately nutrient-enriched lakes in Carmarthenshire, South Wales. The use of diatoms, Pediastrum …

Two Post-Glacial Sagebrush Steppe Fire Records at the Wildland-Urban Interface, Eastern Cascades, Washington
… sediment cores were analyzed using macroscopic charcoal analysis and CharAnalysis software. Relationships between past fire, vegetation, human activities, and climatic drivers, such as the Early Holocene Warm Period, the Medieval Climate Anomaly, the Little Ice Age, and El-Niño Southern …

Out of the Round: A Palaeoecological Investigation into Human-Environmental Interactions of Bronze and Iron Age Hut Circle Communities in Gairloch, Wester Ross
… non-pollen palynomorph (NPP) and microscopic charcoal analysis to investigate evidence for cereal crops, burning events, and changes in vegetational communities over time. The project directly links to research questions posited in the Bronze Age and Iron Age panels of the Scottish …

Post-Glacial Fire History of Horsetail Fen and Human-Environment Interactions in the Teanaway Area of the Eastern Cascades, Washington
… piston corer. High-resolution macroscopic charcoal analysis was used to reconstruct the fire history of the Horsetail Fen watershed. The chronology of the sediment was determined using radiocarbon (<sup>14</sup>C) dating and tephra layer identification. Results of this study show that fire …

Postglacial Reconstruction of Fire History from a Small Lake in Southwest Yukon using Sedimentary Charcoal and Pollen
… a small lake in southwest Yukon. Macroscopic charcoal was counted throughout the core at 0.5-cm contiguous intervals. The core was also analyzed for loss-on-ignition and magnetic susceptibility. Fossil pollen preserved in the lake sediment was analyzed to determine vegetation change throughout …

Holocene Fire History Reconstruction of a Mid-Evaluation Mixed-Conifer Forest in the Eastern Cascades, Washington
… watershed was reconstructed using macroscopic charcoal analysis and pollen analysis was used to reconstruct vegetation change through time. Charcoal results show low fire activity in the early Holocene and the first half of the middle Holocene. After ca. 6000 calendar years before present (cal …

Lake Sediment-Based Reconstructions of Late-Holocene Lowland Environments of Dominican Republic and Barbuda, Northern Caribbean
… in the northern Caribbean primarily through the analysis of proxy data sources contained in sediment cores. At Laguna Alejandro, a coastal lagoon in the southwestern Dominican Republic, we interpreted, from sediment lithology and stable oxygen isotope data, at least ten storm events over the past …

Considering the importance of wetlands to hunter-gatherer adaptation : a microbotanical investigation of Late Pleistocene plant-use in the Eastern Levant
… dissertation is to employ phytolith and micro-charcoal analysis to explore through direct evidence, the long-term patterns of Late Pleistocene hunter-gatherer plant-use in the Eastern Levant. The phytolith data presented in this dissertation demonstrates clearly that wetlands are vital to …

Pioneering new approaches to woodland ecology and human activity in medieval Ireland (c.500-1550AD): an investigation using archaeological charcoal
… period in Ireland using the archaeological charcoal record. It examined the functional and cultural factors that influenced wood selection and wood use during a period of dynamic social, economic and political change and provided valuable insights into discreet local and regional patterns of …

Responses of boreal fire regimes to climatic and land-cover changes: perspectives from multiple spatiotemporal scales
… analyses of the past decade. I used macrocharcoal to reconstruct fire history based on lake-sediment cores collected from 24 lakes in south-central Alaska. These records were compared to regional paleoclimate records to elucidate the response of boreal fire regimes to climate change. To …

Investigating drivers of cyanobacterial blooms in Aotearoa – New Zealand lakes using sedimentary ancient DNA
… a combination of traditional proxies (pollen, charcoal, pigments) and modern proxies (sedimentary ancient DNA, XRF scanning) from lake sediment cores to reconstruct lake ecology in pre-human times, after M¯aori settlement between the 13th to 15th century, and after European settlement from 1840 …
