PhD: Dynamique plurimillénaire des écosystèmes de l’est du Québec et du Labrador: influence des feux et du climat

Description : Deux principaux types de pessières noires caractérisent aujourd’hui les forêts boréales de la portion est de l’Amérique du Nord (Québec méridional) : la pessière noire à mousses et la pessière noire à lichens. Plusieurs auteurs ont démontré que le régime des feux des derniers millénaires a conduit à une ouverture des paysages forestiers par la […]

New paper: 7000-year human legacy of elevation-dependent European fire regimes

Paper Highlights: • 18 southern European charcoal records document 16,000 years of fire regime changes. • Since the Neolithic, land uses have artificially maintained high fire frequencies. • Human-induced decreases in forest cover led to a reduction in the biomass burned. • Human-modified landscapes affected ecological processes more meaningly than expected. Citation: Vannière B., Blarquez […]

PhD opportunity in peatland ecology

The biogeography (https://udembiogeo.wordpress.com/) and paleogeography (http://blarquez.com/) labs at Université de Montréal are seeking a Ph.D. student to work on the impact of fire and other disturbances on long-term peat accumulation in northern peatlands using a mix of paleoecological and modeling approaches. The candidate will need to have a strong background in peatland ecology, paleoecology or […]

ABC platform

We are pleased to share the design of a coring platform we developed with Julie Aleman. The criteria we used for the conception were affordability, the ability to find materials for the construction worldwide, high stability and simplicity. The platform was primarily designed for manipulating Kajak-Brinkhurst, Livingstone or Russian corers, and we were able to recover more than […]

paleofire 1.1.5

A new version of the R package paleofire is available on CRAN at http://cran.r-project.org/web/packages/paleofire/index.html This release includes a new vignette on the basic usage of paleofire for reconstructing regional charcoal composite curves and a new function to easily export GCD sites to Google Earth .kml file. The australasian sites above have been exported using:    

New paper: paleofire: an R package to analyse sedimentary charcoal records from the Global Charcoal Database to reconstruct past biomass burning

I am  pleased to announce the publication of a new study in Computers and Geosciences with Boris Vannière, Jennifer Marlon, Anne-Laure Daniau, Mitch Power, Simon Brewer and Patrick Bartlein. The paper is freely available online here until October 19 and soon as a package vignette for paleofire.   Paper highlights: • We present the open source paleofire R package […]
