Did changing climate in the tropical South Pacific contribute to the eastward migration and settlement of Polynesia
The migration of humans into the eastern Pacific was relatively rapid and focused around 900-1250 CE. Although the causes for this migration are varied, we put forward evidence to suggest that a change in the mean state of the tropical South Pacific from La Niña like to El Niño like conditions accompanied by an increase in climate “shocks” around the period of migration, could have created conditions to promote migration east into the Pacific. We…
Modelling the impact of large-scale hydroclimate change on prehistoric Polynesian island life
The South Pacific was one of the last regions on earth to be colonised by humans and offers a unique opportunity to study early climate-human interactions in environments previously untouched by people. Palaeoclimate evidence suggests the South Pacific has experienced shifts between dry and wet periods throughout the past three thousand years, the broad period of colonisation, with extremes in both modes being prevalent. Drought has significant r…
New integrated molecular approaches for investigating lake settlements in north-western Europe
Lake settlements, particularly crannogs, pose several contradictions—visible yet inaccessible, widespread yet geographically restricted, persistent yet vulnerable. To further our understanding, we developed the integrated use of palaeolimnological (scanning XRF, pollen, spores, diatoms, chironomids, Cladocera, microcharcoal, biogenic silica, SEM-EDS, stable-isotopes) and biomolecular (faecal stanols, bile acids, sedaDNA) analyses of crannog cores…
First human impacts and responses of aquatic systems
Lake sediments constitute natural archives of past environmental changes. Historically, research has focused mainly on generating regional climate records, but records of human impacts caused by land use and exploitation of freshwater resources are now attracting scientific and management interests. Long-term environmental records are useful to establish ecosystem reference conditions, enabling comparisons with current environments and potentiall…
Peat stratigraphy and climate change
Dating the Glen Garry tephra
The distal Icelandic tephra known as the Glen Garry layer has been dated by AMS 14 C at eight ombrotrophic peat bogs from northern England and Scotland. The geochemistry of all the tephra layers is consistent with there being only one Glen Garry tephra, rather than two or more from eruptions of the same volcanic source. At seven of the sites, all in Scotland, the tephra layer was bracketed by 1 cm contiguous samples below, at and above the horizo…
