A 4700-Year Record of Lake Evolution and Fire History for Laguna Limon, Dominican Republic
… from natural or human ignition. Macroscopic charcoal (>125 "m) deposited into lake sediment is a record of a local fire event, whereas microscopic charcoal indicates fire activity on a broad landscape scale. Patterns of charcoal deposition may shed light on both human activities and climate …

Palaeoenvironmental investigations into the human-environmental interactions of prehistoric communities around loch of Stenness, Orkney
… the Stenness area), non-pollen palynomorph and microscopic charcoal analyses, to reconstruct changes in vegetation, environment, and water quality, in and around the Loch of Stenness. Mesolithic and Neolithic communities’ impacts on their landscapes are compared/contrasted and used to …

Late Quaternary fire histories in the eastern Mediterranean region from lake sedimentary micro-charcoals
… delay. This thesis employed lacustrine micro charcoal (particles less than 180 !lm) remains to reconstruct Late Quaternary fire histories for Central Turkey and the Levant, and examine the possible role that fire may have played in retarding woodland development in the region. Microcharcoals …

LATE QUATERNARY FIRE HISTORIES IN THE EASTERN MEDITERRNEAN REGION FROM LAKE SEDIMENTARY MICRO-CHARCOALS
… this delay. This thesis employed lacustrine microcharcoal (particles less than 180 µm) remains to reconstruct Late Quaternary fire histories for Central Turkey and the Levant, and examine the possible role that fire may have played in retarding woodland development in the region. Microcharcoals …

A 1000-year sedimentary record of hurricane, fire, and vegetation history from a coastal lagoon in southwestern Dominican Republic
… ~510-996 cal YBP. All pollen slides contained microscopic charcoal indicating the occurrence of regional or extra-local fires over the last ~1000 yrs. Local fires, as indicated by macroscopic charcoal, occurred before ~434 cal YBP and may be tied to hurricanes, increased moisture in the region …

Out of the Round: A Palaeoecological Investigation into Human-Environmental Interactions of Bronze and Iron Age Hut Circle Communities in Gairloch, Wester Ross
… palynological, 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 …

The Response of High Elevation Wetlands to Past Climate Change, and Implications for the Future
… Last Glacial Maximum. The recoverable pollen and microscopic charcoal records from Harbison Pond begin 8,804 cal yr BP and reveals that fire intensity and frequency was much greater in the early Holocene than present. Warmer and drier conditions than present during the Holocene Climatic Optimum …

Lake Sediment-Based Reconstructions of Late-Holocene Lowland Environments of Dominican Republic and Barbuda, Northern Caribbean
… the pond from abundance of macroscopic (>125 µm) charcoal from sediments representing ~150 BCE–1250 CE, with consistency of burning and human history on the island informed by the archaeological record suggesting fire activity was primarily due to Pre-Columbian inhabitants. Microscopic charcoal …

Seeing the Woods for the Trees: A palaeoecological investigation of past woodlands to inform present and future woodland conservation management strategies in northern Scotland
… pollen, non-pollen palynomorphs (NPP) and microscopic charcoal was used to create long-term, high resolution vegetation records showing changing woodland communities over space and time. The main woodland communities of the past show similarities with present-day semi-natural woodlands in …
