Work Package 1 (understanding of boreal ecosystem functioning)
Photosynthesis and carbon allocation.
During MAIDEN-SPRUCE, we adapted the MAIDEN ecophysiological forest model to consider important processes for boreal tree species, such as non-linear acclimation of photosynthesis to temperature changes, canopy development as a function of previous-year climate variables influencing bud formation and the temperature dependence of carbon partition in summer.
Oxygen isotopes in tree-rings.
During MAIDEN-SPRUCE, we used the MAIDEN model to decipher the variability of δ18O in tree rings of two temperature-sensitive species of relevant paleoclimatological interest (Picea mariana and Nothofagus pumilio) and growing at cold high-latitudes in North and South America.
##
Work package 2 (uncertainties of the climate variability of the last millennium)
During MAIDEN-SPRUCE, we used a new tree-ring dataset (ring widths, δ13C and δ18O) to develop a significantly improved millennium-long multiproxy temperature reconstruction (997-2006 CE) in Northeastern North America accounting for uncertainties with a Bayesian approach that evaluates the likelihood of each proxy model.
##
Work package 3 (legacy of specific past climatic events)
During MAIDEN-SPRUCE, we collected an extensive network of early meteorological time series, climate simulation data and numerous, well-replicated proxy records from Eastern Canada to analyze the strength and the persistence of the Tambora impact on the regional climate and forest processes.
##
Work package 4 (establish long-term collaborations)
MAIDEN-SPRUCE allowed the establishment of a large network of research collaborations within Europe and between American and European scientists. The Experienced Researcher (ER, Fabio Gennaretti) was invited one month at the University of Helsinki (Finland), one week at the CIFOR-INIA Institute (Madrid, Spain), two weeks at the UQAR University (Rimouski, Canada) to strengthen these international collaborations. Furthermore the list of co-authors of the publications resulting from MAIDEN-SPRUCE highlights the importance of this scientific network.
##
Work package 5 (enhance the societal awareness of research diversity)
Following the principles of the European Charter for Researchers and the Code of Conduct for the Recruitment of Researchers, we ensured that our research activities were made known to the society at large by participating to several initiatives and popular science events (National science festival, European Researchers’ Night: Marseille). In these occasions, we did an effort to present our results in such a way that they could be understood by non-specialists. Furthermore, the ER was involved in the co-supervision of two Master students.
