To investigate the extent of ancient agriculture on Easter Island, this study examines pollen, phytoliths and starch preserved in dryland soils at 11 sites across the island. Taxa are variably represented by different types of microfossils, with Arec

To investigate past vegetation change and human activity at the highest elevations on Easter Island, this study examines pollen, phytoliths, diatoms, starch and arthropods preserved in sediment/soil profiles from Rano Aroi crater, and another, newly

Pollen, phytoliths, arthropods and high-resolution 14C sampling from Rano Kau, Easter Island: evidence for late Quaternary environments, ant (Formicidae) distributions and human activity

A 20-m sediment core from Rano Kau, Easter Island provides plant microfossil, arthropod fossil and high-resolution 14C sampling evidence for late Quaternary environments, ant (Formicidae) distributions and human activity. The record commences prior t

Fossil plant remains at Rano Raraku, Easter Island’s statue quarry: evidence for past elevated lake level and ancient Polynesian agriculture

Autor: S. Haoa-Cardinali, John Flenley, T. Edmunds Gorman, L. González Nualart, W. T. Baisden, Mark Horrocks, D. Feek

Publikováno v: Journal of Paleolimnology. 48:767-783

Previous paleoenvironmental records from the lake of Rano Raraku crater, Easter Island’s statue quarry, showed evidence of two major environmental changes, fluctuating lake levels and Polynesian forest clearance. There have been no reports, however

Microfossils of Polynesian cultigens in lake sediment cores from Rano Kau, Easter Island

Autor: Michel K. Nieuwoudt, Mark Horrocks, John Flenley, W. T. Baisden, D. Feek, S. Haoa-Cardinali, T. Edmunds Gorman, L. González Nualart

Publikováno v: Journal of Paleolimnology. 47:185-204

Previous wetland vegetation records from Easter Island showing deforestation and Polynesian agriculture are limited to cores that rely on pollen, with a single cultigen pollen type identified: Urticaceae/Moraceae, possibly Broussonetia payrifera (pap

The Mk II sampler: a device to collect sediment cores for analysis of uncontaminated DNA

Autor: John Flenley, D. Feek, W. T. Baisden, Mark Horrocks

Publikováno v: Journal of Paleolimnology. 45:115-119

We describe an improved piston corer, the Mk II, for sampling soft sediments for ancient DNA analysis. The original Mk I model, designed to minimize contamination and successfully used in New Zealand, was subsequently deployed on Easter Island where

Publikováno v: Quaternary International. 184:139-149

An undisturbed sediment core taken from Round Lake, Hawke's Bay, New Zealand, using a specially designed sterile sampler, has been dated by tephra analysis and radiocarbon and analysed for pollen, charcoal and DNA. It appears to cover the last ca. 36

A modified sampler for uncontaminated DNA cores from soft sediments

Autor: Gerald W. Tannock, D. Feek, John Flenley, P.I. Chester, N. Welikala, Elizabeth Matisoo-Smith

Publikováno v: Journal of Archaeological Science. 33:573-574

A piston-type mud sampler is described. It is a development of the Livingstone corer and was designed to extract cores for DNA analysis of sediments. Prevention of contamination was paramount. As the entire system is self-contained and the sample is
