Call for a new AFS topical issue: Trees, forests and water – recent advances on resistance and resilience to water deficits.

Editors: Erwin Dreyer, Hervé Cochard, Jean Marc Guehl, André Granier (INRAE) ; Maurizio Mencuccini (CREAF). Scope : Ecophysiology and functional ecology of trees and forests have made tremendous progress over the last decades and attracted much attention in

Molecular control to salt tolerance mechanisms of woody plants: recent achievements and perspectives

Key message Woody plants have salt-tolerant mechanisms similar to those developed by non-woody plants. Among others, compartmentalization of ions, production of compatible solutes, synthesis of specific proteins and metabolites, and induction of transcriptional factors are the most

Is vulnerability segmentation at the leaf-stem transition a drought resistance mechanism? A theoretical test with a trait-based model for Neotropical canopy tree species

Key message Leaf-stem vulnerability segmentation predicts lower xylem embolism resistance in leaves than stem. However, although it has been intensively investigated these past decades, the extent to which vulnerability segmentation promotes drought resistance is not well understood.

Disentangling the role of sex dimorphism and forest structure as drivers of growth and wood density in expanding Juniperus thurifera L. woodlands

Key message The dioecious tree species Juniperus thurifera L. is undergoing a spontaneous process of forest expansion in southwest Europe. We investigated how growth, climate sensitivity, and wood density varied simultaneously between sexes and among stages of

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,

Interaction of drought and frost in tree ecophysiology: rethinking the timing of risks

Key message The increase in climate variability is likely to generate an increased occurrence of both frost-induced and drought-induced damages on perennial plants. We examined how these stress factors can potentially interact and would subsequently affect the

An innovative and automated method for characterizing wood defects on trunk surfaces using high-density 3D terrestrial LiDAR data

Key message We designed a novel method allowing to automatically detect and measure defects on the surface of trunks including branches, branch scars, and epicormics from terrestrial LiDAR data by using only high-density 3D information. We could

Exploring new frontiers in forecasting forest growth, yield and wood property variation

Key message Modern forest managers operate in a world characterised by increasing variability in multiple factors impacting forest productivity, survival and product quality. Being able to predict, as accurately as possible, how forests will develop in the

AFS is launching a new topical collection “Sustainable Policies for Wild Fire Management in Forests”

This special issue aims to focus on effective wildfire management in the future by managing long-term resilience and restoration approaches to balance the ecological instability due to wildfires in the forests. Researchers and scholars are welcomed to

Modeling size-density trajectories of even-aged ash (Fraxinus excelsior L.) stands in France. A baseline to assess the impact of Chalara ash dieback

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
