Major Holocene monsoon changes in continental southeast Asia are reconstructed from analysis of C 14 dated changes in pollen and organic/inorganic carbon in sediment cores taken from permanent, closed-basin, volcanic lakes in Ratanakiri Province
, northeastern Cambodia. Analysis focuses on the nature and timing of monsoon changes, inferred from changes in vegetation and lake conditions. This record is also significant for representing a lowland tropical forest setting in Asia.
The aim of this paper is to present a tentative reconstruction of temperature and precipitation changes over the Younger Dryas (YD) and early Holocene periods using both pollen and lake-level data obtained at Le Locle, Swiss Jura. The site of Le

This paper reports a preliminary investigation of the sedimentary succession in 2 alluvial fans in western Norway. Sedimentological information is supplemented by palaeoecological data from pollenanalysis and the age of the sequence is constrained
Pollen assemblage changes and stable hydrogen isotope analysis of mosses from a bog in Tierra del Fuego, Argentina, provided independent proxies for reconstructing changes in effective moisture and temperature over the past 16,000 cal yr B.P
Biomorphic analysis is the study of the macro- and micro-remains of organisms (biomorphs) in the context of the conditions of their origin. Biomorphic analysis can indicate modern and past conditions of pedogenesis and reveal evolutionary trends

The AA. present results of an investigation into past vegetation and climate in the southern Atlantic rain forest region, using pollen and radiocarbon analysises of recently discovered late Pleistocene deposits at Volta Velha, Santa Catarina, Brazil.
Carbon-isotope, diatom, and pollen evidence for Late Holocene salinity change in a brackish marsh in the San Francisco estuary
Analysis of diatoms, pollen, and the carbon-isotopic composition of a sediment core from a brackish marsh in the northern part of the San Francisco Estuary has provided a paleosalinity record that covers the past 3000 yr. Changes in marsh
Combined marine proxy and pollen analyses reveal rapid iberian vegetation response to North Atlantic millennial-scale climate oscillations
A deep-sea sediment core from the western Portuguese margin has provided a continuous, high-resolution record of millennial-scale climatic oscillations during the interval 9000-65,000 yr B.P. Pollenanalysis of the same sequence allows direct

The postglacial vegetation history of Anticosti Island in the Gulf of St. Lawrence, Québec, was reconstructed from pollenanalysis of 3 sites, providing the first paleoecological data for the island. The vegetation history of the island appeared

This paper concerns place and placelessness, and suggests links between those two and types of environmental ethic. An historical analysis of place based ethics and environmental degradation draws on examples from the Pacific basin. Finally
