Climate-growth relationships for Aspidosperma tomentosum Mart. in South American tropical dry forests

Key message The precise demarcation and cross-dating of tree rings in Aspidosperma tomentosum Mart., a valuable timber species in the tropical dry forests of South America, were used to develop the first well-replicated chronology covering the period

Competition overrides climate as trigger of growth decline in a mixed Fagaceae Mediterranean rear-edge forest

Key message In recent decades, there has been a decline in growth in a rear-edge broadleaf forest of Fagus sylvatica, Quercus petraea, and Quercus pyrenaica. Although temperatures have been rising due to climate change, the observed decline

First evidence for allotriploid hybrids between Juniperus thurifera and J. sabina in a sympatric area in the French Alps

Key message Discovery of the first case of allotriploid juniper in a wild population in the French Alps where the parental species occurs in sympatry. Abstract Context Interspecific hybridization and polyploidy are important evolutionary phenomena in vascular

Age effect on tree structure and biomass allocation in Scots pine (Pinus sylvestris L.) and Norway spruce (Picea abies [L.] Karst.)

Key message Tree structure equations derived from pipe model theory (PMT) are well-suited to estimate biomass allocation in Scots pine ( Pinus sylvestris L.) and Norway spruce ( Picea abies [L.] Karst.). However, age dependence of parameters

Forest decline differentially affects trophic guilds of canopy-dwelling beetles

Key message Decline can affect the structure, resources, and microclimates of the forest canopy, and potentially have cascading effects on canopy-dwelling species. Our survey shows that an oak decline can promote saproxylic beetles, especially xylophagous ones, and

Radial growth anisotropy and temporality in fast-growing temperate conifers

Key message Radial growth in a group of Pinus radiata D. Don. trees varies in magnitude around the circumference and follows synchronous but arrhythmic dynamics. Abstract Context Eccentric and irregular girth growth is typically associated to specific

Variation in leaf anatomy, vascular traits and nanomechanical cell-wall properties among European beech (Fagus sylvatica L.) provenances

Key message Structural and ultrastructural traits of leaf xylem vary among European beech ( Fagus sylvatica L.) provenances in relation to climate. High tracheary element lumen area was observed in central Europe and decreased towards the range

Genome-wide analysis of evolution and expression profiles of NAC transcription factor gene family in Juglans regia L.

Key message NAC transcription factors may play important roles in the biological processes in Persian walnut. A total of 102 JrNAC s were identified in Persian walnut. The conserved domains, transcriptome profile, expression analysis, and interaction network

Social sciences have so much more to bring to climate studies in forest research: a French case study

Key message Faced with wicked problems such as climate change, managers of complex forest social-ecological systems require more than experimental sciences alone. Yet, mitigation and adaptation studies underuse social sciences in forest research, as shown here with

Tree potential growth varies more than competition among spontaneously established forest stands of pedunculate oak (Quercus robur)

Key message Analyses of dendrochronological data from 15 recently established tablished stands of pedunculate oak (Quercus robur L.) revealed that functions describing potential tree growth in the absence of neighbours varied more between stands than functions describing
