Potential distributions of seven sympatric sclerophyllous oak species in Southwest China depend on climatic, non-climatic, and independent spatial drivers
By Véronique Lesage On 15 January 2021 In All published articles, Data in repository, Research paper
Key message An ensemble modelling approach was performed to predict the distributions of seven sympatric sclerophyllous oak species in the Hengduan Mountains of Southwest China. Spatial eigenvector filters revealed missing factors in addition to commonly used environmental

Analysis of plot-level volume increment models developed from machine learning methods applied to an uneven-aged mixed forest
Key message We modeled 10-year net stand volume growth with four machine learning (ML) methods, i.e., artificial neural networks (ANN), support vector machines (SVM), random forests (RF), and nearest neighbor analysis (NN), and with linear regression analysis.

Modeling size-density trajectories of even-aged ash (Fraxinus excelsior L.) stands in France. A baseline to assess the impact of Chalara ash dieback
By Véronique Lesage On 13 January 2021 In All published articles, Data in repository, Research paper, Special issue/Topical collection
Key message A piecewise polynomial function already used to represent the size-density trajectories of pure even-aged stands of beech, oak, and Douglas-fir proved its ability to represent the size-density trajectories of a new species, ash. The widespread

Accounting for competition in multi-environment tree genetic evaluations: a case study with hybrid pines
By Véronique Lesage On 11 January 2021 In All published articles, Data in repository, Research paper
Key message A novel multi-environment competition individual-tree mixed model resulted in better fit, and greater individual narrow- and broad-sense heritabilities than the model without competition, notably for traits showing competition. In multi-environment tests, the proposed model would

Secondary metabolites in leaves of hybrid aspen are affected by the competitive status and early thinning in dense coppices
Key message Non-selective thinning of a hybrid aspen coppice stands via corridor or cross-corridor cutting impacts residual trees differently depending on their competitive status. Suppressed residual trees’ metabolic profile indicates increased stress level, especially after cross-corridor thinning.

Does recent fire activity impact fire-related traits of Pinus halepensis Mill. and Pinus sylvestris L. in the French Mediterranean area?
By Véronique Lesage On 17 November 2020 In All published articles, Data in repository, Research paper
Key message Climate change will induce a change in fire frequency in Mediterranean region and that could impact fire-adapted plant species. We showed that fire-related traits of some pine species are strongly related to other factors than

Drought responses and their effects on radial stem growth of two co-occurring conifer species in the Mediterranean mountain range
By Véronique Lesage On 4 November 2020 In All published articles, Data in repository, Open Access, Research paper
Key message Patterns of stem radial variations showed that Cedrus libani A. Rich. was less limited by summer drought than co-occurring Juniperus excelsa M. Bieb. Cedrus libani recovered faster from tree water deficit and showed significantly higher

Improving aboveground biomass estimates by taking into account density variations between tree components
Key message Strong density differences were observed between stem wood at 1.30 m and other tree components (stem wood, stem bark, knots, branch stumps and branches). The difference, up to 40% depending on the component, should be

Extended xylogenesis and stem biomass production in Juniperus przewalskii Kom. during extreme late-season climatic events
Key message Late-season extreme climatic events induced variations in wood density and extended growth for more than a month in 2016 in Juniperus przewalskii Kom. growing on the Northeastern Tibetan Plateau, suggesting extraordinary growth resilience of the

Unprecedented pluri-decennial increase in the growing stock of French forests is persistent and dominated by private broadleaved forests
Key message French forests exhibit the fastest relative changes across Europe. Growing stock increases faster than area, and is greatest in low-stocked private broadleaved forests. Past areal increases and current GS levels show positive effects on GS
