A PhD opportunity in dendrochronology and silviculture of boreal mixewoods:

Site productivity dynamics following silvicultural treatments in boreal mixedwoods


Announcement in PDF format pdfpic


Context. Forest productivity and sustainable management of forest resources are among the main preoccupations of today's Canadian forestry. An increasing body of recent research indicates that future forestry may benefit from its higher reliance on mixed forests, which may reduce climate-related risks for wood production. Currently, however, the transition towards mixed forest silviculture is slow due to insufficient amount of knowledge, both practical and theoretical, on such new management programs. Novel silvicultural practices, such as partial harvesting and variable tree retention, has been receiving particular attention in this respect as ways to improve long term forest resilience and increase biodiversity value of commercially managed forest landscapes. It is expected that the forest industry in the coming decades will increase its dependence on mixedwoods. This particularly applies to the mixtures of shade-intolerant hardwoods with coniferous species, primarily - jack pine, white and black spruce and fir.


The doctoral project will seek to assess the role of pre-thinning conditions, specifically - stand canopy and understory composition, in controlling the effects of thinning on stand productivity. The project will evaluate whether partial thinning of the mixed stands modify their susceptibility to environmental extremes, which in turn affect stands' long-term productivity potential. Our final goal in this project is to define species combinations provide the biomass productivity rates which are the most resilient towards future environmental variability and may therefore be considered as the most economically sound silvicultural options.


PhD student. We are looking for an ambitious and highly motivated PhD student with a completed master degree in forest ecology, climatology, geography, or ecosystem modelling. Documented experiences with dendrochronology, forest genetics, and large relational databases are strong assets during the evaluation process. The knowledge of R is an absolute must.  The candidate should be fluent in English and has a good ability to formulate himself/herself both orally and in writing. Knowledge of French is a strong asset. A record of scientific publications is highly valued. We put a great emphasis on personal characteristics of the successful applicant, solid work ethics, ability to work in a team, and the ability to independently manage a large volume of laboratory and analytical tasks and to meet reporting and publication deadlines. The candidate is expected to be physically fit.


Location.The student will be based at the Forest Research Institute of the University of Quebec at Abitibi-Temiscamingue (IRF UQAT, Rouyn-Noranda QC). The student will become a member of the Chair in Sustainable Forest Management and the Center for Forest Studies. The IRF team enjoys a highly dynamic and truly international research environment. The city of Rouyn-Noranda is very active culturally and offers a high quality of life thanks to its tourist attractions (Film Festival, Music Festival Emerging, World Guitar Festival to name a few) and a large number of outdoor activities which include hiking, camping, canoeing, skiing, and snowshoeing (; /).


Beginning of studies: under 2018


Funding: a fellowship of Can$ 20,000 per year for a total of three years.


Supervision: Igor Drobyshev, Benoir Lafleur, Yves Bergeron  (IRF UQAT).

Interested candidates must apply by e-mail ( by sending (1) a cover letter outlining their academic background and research experience, as well as (2) a detailed CV including name and contact information of  two references.
