We present a 211-year tree-ring-based reconstruction of the annual mean flow of the Sainte Anne River, Gaspésie, Québec, Canada. The river traverses through the interior of the Gaspé Peninsula where the instrumental hydrological and climatic records are particularly short. This is the first streamflow/soil moisture reconstruction between the Hudson River and north-central Québec, filling a substantial geographical gap along the eastern North American margin, and adding to the only three ex...

How old are tropical trees? This fundamental question has long driven the curiosity of laymen and scientists. But only recently, a great number of studies conducted by many brave dendrochronologists resulted in a significant tree-ring-based knowledge that allows us to start accurately estimating tree ages across the globe. As science goes, not only knowing the longevity of tropical trees is essential to understanding forest dynamics and its role in biogeochemical cycles, but one must also ...

A gap of millennial tree-ring data suitable for dendroclimatology has long been evident in the North American boreal forest. In my talk, I will describe the adaptive approach we have developed to build and improve a data network for millennial dendroclimatology in the eastern Canadian taiga. Recurrence of stand replacing wildfires is the most important constrain to the elaboration of long tree ring chronologies, which can only be developed away from regions ...
