No matter how much space and light are available, radial growth distribution in Fagus sylvatica L. trees is under strong biomechanical control

Key message This study presents the first attempt to quantify how the thigmomorphogenetic syndrome is involved in Fagus sylvatica L. tree growth responses to thinning. An experimental design preventing mechanosensing in half of the trees demonstrated that

Pinus pinea: a natural barrier for the insect vector of the pine wood nematode?

Key message In mixed stands of Pinus pinaster and Pinus pinea, fewer insect vectors of the pinewood nematode (PWN) were captured than in pure P. pinaster stands. This finding has practical implications for PWN disease management, including

Combining Weibull distribution and k-nearest neighbor imputation method to predict wall-to-wall tree lists for the entire forest region of Northeast China

Key message We propose a coupled framework to combine the strengths of the Weibull function in modeling diameter distributions and the ability of the k-nearest neighbor (kNN) method to impute spatially continuous forest stand attributes for the

Identification and spatial extent of understory plant species requiring vegetation control to ensure tree regeneration in French forests

Key message Fifteen species are most susceptible to require vegetation control during tree regeneration in the range of our study. Among these 15 species, Rubus fruticosus, Pteridium aquilinum, and Molinia caerulea cover each more than 300,000 ha

Classification of forest fuels in selected fire-prone ecosystems of Alberta, Canada—implications for crown fire behaviour prediction and fuel management

Key message We used clustering to construct fuel classes from fuel inventory data based on three stand attributes relevant to crown fire behaviour: surface fuel load (SFL), canopy base height (CBH) and canopy bulk density (CBD). Resulting

Increasing the intensity of regeneration treatments decreased beta diversity of temperate hardwood forest understory 20 years after disturbance

Key message In temperate hardwood forests of Southern Quebec, silvicultural treatments of higher intensities resulted in detrimental effects on soil properties, especially in the surface horizon, 20 years after disturbance. This legacy, in turn, affected the composition

Population history, genetic variation, and conservation status of European white elm (Ulmus laevis Pall.) in Poland

Key message The core populations of the European white elm (Ulmus laevis Pall.) located in Poland maintained slightly higher level of genetic diversity compared to the peripheral populations of this species. Keywords Central-marginal populations; Bottleneck; Microsatellites; DED

Spatial optimization of genetic thinning in seed orchards

Key message We provide a mathematical model to determine which trees should be ruled out from the grid to promote random mating in seed orchards under genetic thinning. Keywords Seed orchards; Spatial layouts; Panmixis; Optimum-Neighborhood Algorithm; Linear

De novo transcriptome assembly reveals characteristics of flower sex determination of Excoecaria agallocha

Key message MADS-box genes family may play important roles in the flower sex determination in Excoecaria agallocha. A total of 73 MADS-box genes were identified in E. agallocha. De novo transcriptome assembly analysis suggested that AP1/FUL, AP3/PI,

Climate envelope analyses suggests significant rearrangements in the distribution ranges of Central European tree species

Key message Climate envelope analysis of nine tree species shows that Fagus sylvatica L. and Picea abies H. Karst could lose 58% and 40% of their current distribution range. Quercus pubescens Willd and Quercus cerris L. may
