Potential of machine learning and WorldView-2 images for recognizing endangered and invasive species in the Atlantic Rainforest

Key message We found high accuracy classification (Fmeasure = 95%, on cross-validation) of Araucaria angustifolia (Bertol.) Kuntze, an endangered native species, and Hovenia dulcis Thunb. an aggressive, invasive alien species in WorldView-2 multispectral images. In applying machine

Oviposition preference of the forest cockchafer (Melolontha hippocastani Fabr. 1801) at the stand scale depends on oak proportion, canopy openness and ground accessibility

Key message Melolontha hippocastani is a major pest in European mixed and broadleaf forests. Investigating its oviposition behavior, we observed that a dense shrub layer reduces the density of egg clusters and eggs in the soil. Conversely,

Variation of cork porosity along the stem in harvested cork oak (Quercus suber L.) trees

Key message Cork porosity, due to lenticular channels, varied along the stem of Quercus suber L. Lenticular channels’ area, rather than their number, decreased upwards along the stem. Area decrease was observed regardless of tree size and

Estimating the willingness to pay for regulating and cultural ecosystem services from forested Siwalik landscapes: perspectives of disaggregated users

Key message We assessed forest users’ willingness to pay (WTP) for regulating and cultural forest services based on their socio-economic status (rich vs. poor), proximity to forests (nearby vs. distant), and forest management modalities (community forestry vs.

SurEau: a mechanistic model of plant water relations under extreme drought

Key message A new process-based model, SurEau , is described. It predicts the risk of xylem hydraulic failure under drought. Abstract Context The increase in drought intensity due to climate change will accentuate the risk of tree

Genetic gains in wood property can be achieved by indirect selection and nondestructive measurements in full-sib families of Japanese cedar (Cryptomeria japonica. D. Don) plus tree clones

Key message We assessed the narrow-sense heredity and genetic gains of multiple traits obtained using the indirect selection method for progeny of Cryptomeria japonica D. Don by artificial crossing. Using stress wave velocity and Pilodyn penetration depth

Timber volume estimation based on airborne laser scanning — comparing the use of national forest inventory and forest management inventory data

Key message Large-scale forest resource maps based on national forest inventory (NFI) data and airborne laser scanning may facilitate synergies between NFIs and forest management inventories (FMIs). A comparison of models used in such a NFI-based map

Contributions of Leguminosae to young and old stands of neotropical forests under different environmental conditions

Key message Potentially nodulating Leguminosae species had high density and biomass in young stands of forests in Northeast Brazil, except in a dry forest on a low-fertility soil. Abstract Context Leguminosae species, especially potentially nodulating ones, appear

The relationship between plant growth and water consumption: a history from the classical four elements to modern stable isotopes

Key message The history of the relationship between plant growth and water consumption is retraced by following the progression of scientific thought through the centuries: from a purely philosophical question, to conceptual and methodological developments, towards a

Combined effects of natural disturbances and management on forest carbon sequestration: the case of Vaia storm in Italy

Key message Natural disturbances and management are key drivers for forest carbon balance. We modelled the impact of Vaia storm on forest sink at national scale in Italy. We demonstrate that after Vaia, carbon fluxes among pools
