New paper: Land-use change outweighs projected effects of changing rainfall on tree cover in sub-Saharan Africa

I am pleased to share this new article with Julie Aleman and Carla Staver: DOI: 10.1111/gcb.13299 (preprint) about modelling of future tree cover in sub-Saharan Africa. Abstract:  Global change will likely affect savanna and forest structure and distributions, with implications for diversity within both biomes. Few studies have examined the impacts of both expected precipitation and […]

New paper: Biomass offsets little or none of permafrost carbon release from soils, streams, and wildfire: an expert assessment

I am pleased to share this new article based on an expert assessment approach leaded by Ben Abbott. The paper is available via http://iopscience.iop.org/article/10.1088/1748-9326/11/3/034014/meta;jsessionid=B9105E9A62A05ADEBDBD3CAA8F3A4A64.c3.iopscience.cld.iop.org Abstract: As the permafrost region warms, its large organic carbon pool will be increasingly vulnerable to decomposition, combustion, and hydrologic export. Models predict that some portion of this release will be offset by […]

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 […]
