The relationships between forest biodiversity and functioning will be deciphered through better understanding of the respective role of tree species richness and composition and by focussing on the biotic interactions between species. As the fundamental ecological hypothesis behind the diversity productivity relationship is the optimal use of resources, we will analyse the energy flow (i.e. resources production and consumption) across different trophic levels (trees and symbiotic organisms as producers, herbivores and pathogens as consumers).
In a final step we will aggregate the information from the first two steps to predict the effect of climate change on forest productivity through changes in tree species composition. The prediction will be expressed as a risk of dysfunction, in particular the risk of forest productivity loss. Traditionally, the risk for a given system is a function of hazard probability and system vulnerability to this hazard. In this case, hazards will be changes in average and extreme climatic conditions. Vulnerability will be the vulnerability to climate change of forest species that both shape forest composition and are the main drivers of forest biomass productivity. In each step, we will focus on fundamental ecological processes at work so that to deliver more generic scientific outcomes that will allow easier generalization to diverse types of European forest or forest managers expectations than a case by case approach.
PROJECT GOALS:Forecasting forest diversity under the influence of climatic changes and the consequences for stability and productivity of forest ecosystems
Evaluate the effect of climate change on tree mycorrhiza, pest herbivores, their natural enemies and fungal or oomycete pathogens. In particular the objective is to focus on response variables to climate change that are both relevant to forest biodiversity and functioning: species composition and population attributes such as abundance and spatial distribution.
Determine the role played by biodiversity in the performance of forests in terms of net primary production i.e. difference between biomass production by trees and biomass consumption or degradation by herbivores and pathogens.
specifically the objective is to disentangle the respective roles played by the richness (how many species?), the functional diversity (how dissimilar are they?), and the composition (which are they?) of tree species in the functioning of mixed forests.
Rate the risk of forest productivity loss under climate change scenarios by designing, developing and implementing conceptual models that will loop the loop; i.e. will relate the vulnerability of forest functioning to forest composition.
The technological objectives of BACCARA are to:
Rank the risk of species loss or changes in proportion in the main European forest categories according to their composition
Give recommendations on tree species composition in order to optimise forest net productivity
Provide guidelines for the construction of user friendly abacuses ranking the risk of loss in forest biomass productivity according to forest tree composition in the main European biogeographical zones.
Design, develop and implement a decision-support system aimed at balancing costs and benefits for the establishment of new forest composition in order to anticipate and mitigate the potential detrimental effects of climate changes on forest productivity.
The effect of climate change on forest biodiversity will be evaluated through better understanding of the ecological processes that shape species composition and are particularly sensitive to climate conditions. Forest species composition will be determined as the assemblage of tree species and both mutualistic and antagonistic species that drive tree species composition. Climate conditions will include both average and extreme values of climatic variables (e.g. temperature, humidity and wind).
The relationships between forest biodiversity and functioning will be deciphered through better understanding of the respective role of tree species richness and composition and by focussing on the biotic interactions between species. Energy flows (i.e. resource production and consumption) across different trophic levels (trees and mutualists as producers, herbivores and pathogens as consumers) will be analysed since the fundamental ecological hypothesis behind the diversity–productivity relationship is the optimal use of resources.
In each step, we will focus on fundamental ecological processes at work to deliver
generic scientific outcomes enabling easier generalization to diverse types of European forest and forest manager expectations than found in a case by case approach.
