A suite of 23 14C age determinations, from a well-stratified rockshelter and from 3 pollen cores on Mangaia Island is reported. The rockshelter has yielded significant evidence for avifaunal…

A 7000-year-long sequence of environmental change during the Holocene has been reconstructed for a central Pacific island (Mangaia, Cook Islands). The research design used geomorphological and…
The Tangatatau Rockshelter (site MAN-44, Mangaia, Cook Islands) has produced one of Eastern Polynesia's most comprehensive chrono-stratigraphic sequences of artifacts, vertebrate and invertebrate…
A sediment core from a high-elevation bog on Maui in the Hawaiian Islands contains evidence for drier conditions between 9.4–5.8 kyr BP, followed by a wetter interval between 5.8–2.2 kyr BP, and a…
An 8 m sediment core from Laguna Tortuguero, Puerto Rico, provides a 7000 calendar year history of fire occurrence and sedimentation on the island's north coast. After c. 5300 cal-BP, microscopic…
A 4.3 m‐long peat sequence from the shore of Lake Tiriara, Mangaia, Cook Islands, was analyzed using an ITRAX core scanner equipped with a magnetic susceptibility meter. Variations in the elemental…
We present pollen diagrams and sedimentological analyses from a lake site within an extensive dune system on the Aupouri Peninsula, Northland. Five thousand years ago, a regional Agathis australis --…
We report on the text excavation of a small trench at the coastal site of Ahu Nau- nau, Anakena, Easter Island (Rapanui), Chile. The cultural deposits are a basal silty clay overlain by up to 1.3 m…
Abstract Archaeological investigations of the prehistoric colonization of East Polynesia have focused on the question: when did this event occur? A relatively late date for the colonization of…
ABSTRACT Information from cores into the offshore reefs of Komebail Lagoon and into the coastal fringes of Babeldaob and neighboring islets allows the first well-constrained appraisal of the Holocene…
Easter Island is the most isolated piece of inhabited land in the world. It exhibited an unique megalithic culture1–3, involving the sculpting of giant statues (moai) especially between AD ∼1400 and…

TLDR
Sediment cores from a lake 0.9 km from MAN-44 show clear palynological and stratigraphic signals of human presence on Mangaia, especially forest clearance of the volcanic interior, beginning at 1600 yr B.P.
Evidence obtained from archaeological and ancillary studies of paleoenvironment suggests that the prehistoric Polynesians had a far greater impact on the Hawaiian ecosystem than has heretofore been…
The radiocarbon ages of dendrochronologically dated wood samples, each covering 10 years, are reported back to 2500 yr BC. The decadal calibration curve constructed from these data is an extension of…
By the time of European settlement a large proportion of the lowland area of New Zealand was without forest (Fig. Id). That this was not a natural state was readily apparent in the North Island where…
Two species of rails, Porzana rua n. sp. and Gallirallus ripleyi n. sp., are described from bones of late Holocene age found in caves on Mangaia, southern Cook Islands. Their relatively small…
