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.
