Some ombrotrophic peatlands in temperate regions have been characterized by a process of rapid densification of their forest cover for several decades. This phenomenon is particularly marked in southern Québec (Canada), where a number of peatlands n

Summary 1. Macroscopic sedimentary charcoal and plant macroremains from two lakes, 50 km apart, in north-western Ontario, Canada, were analysed to investigate fire frequency and tree abundance in the central boreal forest. These records were used to

Paleoecological investigations of organic-rich sediments and radiometric dating of fossil wood fragments were undertaken to constrain the age of an extensive pre-Holocene nonglacial sediment sequence exposed along the Nottaway River in the southeaste

De nouvelles datations à l'accélérateur de particules des premiers macrorestes végétaux terricoles accumulés dans les sédiments postglaciaires d'une douzaine de lacs répartis en Gaspésie et au Bas-Saint-Laurent bouleversent entièrement la c

Un mince dépôt de versant fossile a été observé sous 45 m de sédiments quaternaires appartenant à la séquence supérieure du Wisconsinien classique de la vallée du Saint-Laurent. Il repose sur des sédiments ayant donné un âge au 14C >39 9

L'analyse poliinique, l'analyse macrofossile, ainsi que la datation au radiocarbone de quatre carottes de sédiments lacustres postglaciaires, ont permis d'établir l'âge minimal de la déglaciation et l'histoire postglaciaire de la végétation dan

Old-growth forests make up a substantial proportion of the forest mosaic in the Clay Belt region of Ontario and Quebec, Canada, despite fire cycles that are presumed to be relatively short. Two hypotheses have been suggested as explanations for this

The charcoal content from laminated lake sediments in Québec, Canada, was estimated from pollen slides and by a sieving method. The resulting charcoal series are compared to estimate the suitability of these two methods to provide a local or regiona

The sedimentary sequence in a coastal pond on Cape Breton Island was examined by various analyses (pollen, plant macrofossils, diatoms, and rhizopods). The results allow for the reconstruction of different phases in the evolution of the pond in conju
