Description:

 

These two positions are part of the EU FP7 project BACCARA (Biodiversity

And Climate Change: A Risk Analysis). The goal of this project is to

evaluate risks of European forest biodiversity and productivity loss

under climate change focussing on forest trees and associated species

(mainly insects and pathogens). In this project our team focuses on the

relations between climate, tree demography, tree functional diversity

and productivity in the Alps. We participate both to the

observational/experimental and to the modelling effort in this project.

 

The objective of these post-doc projects are to assess the risk of

change in productivity and mortality due to climate changes in mountain

forests. More specifically the goal is to rate the risks of dysfunction

(loss of forest cover) and loss of productivity due to the effects of

climate change in forest of different functional and phylogenetic

compositions. The project will be organised around the

diversity-stability paradigm. Adapted to our context, this paradigm

states that more diverse communities should experience less risks of

dysfunction and loss of productivity due to climate change. Functional

diversity will be analysed based on traits related to climate stress

tolerance (for instance a low tolerance of water stress), but we will

also consider traits related to competitive ability (for instance shade

tolerance). We consider that tree-tree interactions are keys to

understand the response of forest communities to global change. Our

approach will be based both on a retrospective analysis of National

Forest Inventory (NFI) data covering a 50 years period and the

development of an individual based model of growth and mortality. The

model will be used to forecast future change in tree growth and

mortality based on climate scenarios. We will make use of recent advance

in Hierarchical Bayesian statistic to analyse this large data set. We

have developed non manipulative methods to analyse tree growth and

mortality response to tree-tree interaction and to climate effects.

These growth and mortality model will be used to forecast changes of

stand productivity and mortality of virtual communities of varying

functional composition.

 

The post-doctoral fellowship is proposed in the Mountain Ecosystem

Research Unit, Cemagref Grenoble. The unit studies mountain forest and

grassland ecosystems of the Alps, to develop basis for their sound and

sustainable management. We develop a multifunctional approach of forest

ecosystem services with special focus on forest diversity and protection

efficiency against natural hazards. The work of the team is based on

Samsaraa simulation model in the simulation software Capsis, which used

to train forest managers.

 

 

Education:Required qualifications include a PhD degree in the fields of

ecology, forestry, environmental science or related field. Preference

will be given to candidates who have experience in R statistical

software, modelling, or Hierarchical Bayesian statistics.

 

 

Conditions:

 

Work will be located in Cemagref in Saint-Martin-d’Hères near Grenoble.

 

Grosssalary will be of 2200 €/month.

 

Duration of appointment 19 months for one position and 14 months for the

second position. To start as soon as possible .
