The rooting ability of in vitro shoot cultures established from a UK collection of the common ash (Fraxinus excelsior L.) and their ex vitro surviva

Key message Shoot cultures from a population of British ash trees (Fraxinus excelsior L.) were assessed for their ability to form roots in vitro and to grow in nursery conditions. Most of the plants survived whether they

Potential soil methane oxidation in naturally regenerated oak-dominated temperate deciduous forest stands responds to soil water status regardless of their age—an intact core incubation study

Key message Potential CH4 oxidation in the top soil layer increased with decreasing soil water content in spring but was inhibited during severe summer drought in naturally-regenerated oak-dominated temperate deciduous forest stands regardless of their age. No

Provenance variation and seed sourcing for sessile oak (Quercus petraea (Matt.) Liebl.) in France

Key message Sessile oak (Quercus petraea (Matt.) Liebl.) provenance variation was assessed in a multisite test based on traits of economic and ecological relevance in France. While climatic drivers generated genetic clines at a range-wide scale, provenance

Estimating gap age using tree-ring width in combination with carbon isotope discrimination in a temperate forest, Northeast China

Key message The accuracy of gap age estimation can be improved from 5–6 to 2 years by analyzing the annual width and carbon isotope discrimination of the rings of gap-surrounding trees. Keywords Canopy opening; Gap formation; Tree

Nitrogen deposition causes eutrophication in bryophyte communities in central and northern European forests

Key message Our results indicate that nitrogen deposition is likely to adversely affect forest bryophyte communities, having negative impacts in terms of increased dominance of nitrophilic species at the expense of N-sensitive species and a decrease in

Climate change-induced background tree mortality is exacerbated towards the warm limits of the species ranges

Key message An influence of the recent changes in temperature or rainfall was demonstrated, increasing background tree mortality rates for 2/3 of the 12 studied tree species. Climate change-induced tree mortality was exacerbated towards the warm or

Stand development stages and recruitment patterns influence fine-scale spatial genetic structure in two Patagonian Nothofagus species

Key message Nothofagus alpina (Poepp. et Endl.) Oerst. and Nothofagus obliqua (Mirb.) Oerst forests have strong fine-scale spatial genetic structures. The intensity of genetic structure patterns differed according to species, stand development stages, life stages, and spatial

Spruce (Picea abies L.) planting leads post-clearcut bird assemblages to a novel successional pathway—a comparative study in hemiboreal mixed forests

Key message Bird assemblages in planted spruce (Picea abies L.) forests were compositionally distinct from those in naturally regenerated mixed stands. Despite rapid stand development on productive soils, even-aged silviculture cannot host most old-forest species. However, their

Responses to defoliation of Robinia pseudoacacia L. and Sophora japonica L. are soil water condition dependent

Key message Defoliation significantly affected biomass allocation of Robinia pseudoacacia L. and Sophora japonica L., but leaf physiology readjusted to control levels at the end of the experiment. Considering carbon or sink limitation and relative height growth

Recolonization by Indigenous broadleaved species of a conifer plantation (Cupressus spp.) in Northern Iran after 25 years

Key message A vegetation analysis revealed the extent of recolonization by native vegetation of a 25-year-old Cupressus spp. plantation in northern Iran. A young indigenous Quercus-Carpinus community replaced the conifers in the low-slope areas with deeper, heavier,
