Summary Forest dieback caused by drought‐induced tree mortality has been observed world‐wide. Forecasting which trees in locations are vulnerable to is important predict the consequences of drought on forest structure, biodiversity and ecosystem function. In this paper, our central aim was compile a synthesis traits associated abiotic variables that can be used mortality. We reviewed literature specifically links functional site conditions (i.e. edaphic biotic conditions), targeting studies...

Abstract In anticipation of a drier climate and to project future changes in forest dynamics, it is imperative understand species-specific differences drought resistance. The objectives this study were form comprehensive understanding the resistance strategies adopted by Eastern Mediterranean woodland species, elaborate specific ecophysiological traits that can explain observed variation survival among these species. We examined leaf water potential (𝛹), gas exchange stem hydraulics during...

Wood ash fertilization remarkably increases tree growth and hence, carbon sequestration in drained boreal peatland forests, particularly nitrogen (N)-rich Scots pine sites with limited phosphorus (P) potassium (K). Because lacks N, N-deficient ombrotrophic poor oligotrophic are generally considered unsuitable for fertilization. In this study, timber production was investigated six field experiments N-poor, dominated peatlands central Finland, where applied 15–85 years earlier. Ash...

We developed tree level biomass (dry weight) models for Norway spruce (Picea abies [L.] H. Karst.), silver birch (Betula pendula Roth), rowan (Sorbus aucuparia L.) and aspen (Populus tremula growing in young dominated seedling stands with high mixture of broadleaves. The study material was collected from three planted located on mineral soil southern Finland. Biomass were estimated by individual component (stem, living branches, foliage, stump, roots diameter 2 mm) using a multi-response...
