Shaping future forests: how can ecophysiology support climate‐smart forest management?

New Phytologist, Volume 250, Issue 5, Page 2778-2813, June 2026.
Summary Climate change, particularly the associated increase in extreme events and disturbances, threatens the numerous environmental, social, and economic benefits that forests provide, both locally and globally. Heat and drought pose significant risks to forest ecosystems; the anticipated future climate is expected to exacerbate this trend ...

Variation in Wood Quality in White Spruce (Picea Glauca (Moench) Voss). Part I. Defining the Juvenile–Mature Wood Transition Based on Tracheid Length

, 2015
Estimations of transition age (TA) and juvenile wood proportion (JWP) are important for wood industries due to their impact on end-product quality.

Variation in reproductive potential across a multi-species treeline

Arctic, Antarctic, and Alpine Research, 2018
Cone and seed production at the forest-tundra ecotone, or treeline, depend on species-specific tolerances to limiting abiotic and biotic factors. As range expansion via seed dispersal is needed to keep pace with climate change, reproductive limitations ...

Effective Conservation Decisions Require Models Designed for Purpose: A Case Study of Boreal Caribou in Ontario's Ring of Fire

Ecology and Evolution, Volume 16, Issue 5, May 2026.
Decision making in conservation science often relies on the best available information, but existing models are rarely reproducible, transferrable, or accessible. We sought to reproduce and evaluate the suitability of the two best available models for predicting impacts of proposed mining on boreal woodland caribou (Rangifer tarandus caribou) in ...

PREDICTION OF TRACHEID LENGTH AND DIAMETER IN WHITE SPRUCE (PICEA GLAUCA)

, 2015
The establishment of patterns of radial and longitudinal variations and the development of models to predict the wood anatomical properties, especially from juvenile wood, are of interest for both wood industry and researchers.

Influenţa stadiului de pornire în vegetaţie a portaltoiului şi a nivelului de altoire asupra procentului de prindere în cazul altoirii la molidul argintiu[Influence of the parent stock phenology and grafting level on successfull grafting of silver Colorado spruce] [PDF]

Bucovina Forestieră, 2014
Having no importance for Romanian forestry, Picea pungens Engelm. is an ornamental species, often seen in Romanian parks and gardens. There are cultivated especially glauca and argentea forms. The biggest problem of this forms is getting seedlings.

Mycorrhizae and Rhizobacteria on Precambrian Rocky Gold Mine Tailings: II. Mine-Adapted Symbionts Alleviate Soil Element Imbalance for a Better Nutritional Status of White Spruce Seedlings

Frontiers in Plant Science, 2018
In the context of a phytorestoration project, the purpose of this study was to assess the respective contribution to the nutritional status of Picea glauca seedlings of ectomycorrhizae and rhizobacteria native or not to the Sigma-Lamaque gold mine wastes

Tree communities face rising soil water deficits exposure under projected climate change in northern temperate forests

Ecosphere, Volume 17, Issue 5, May 2026.
Abstract Soil water deficits in temperate forests are projected to become more frequent, more severe, and longer in duration. This study aims to quantify the current (1981–2010) and projected (2041–2070) exposure of 17 tree communities to soil water deficit (severity and duration) in southwestern Quebec, Canada, using the Canadian Land Surface Scheme ...

FROM STUDIES ON POSSIBILITY OF PROTECTING BLUE SPRUCE (Picea pungens Engelm.) AGAINST FUNGI. PART I. LABORATORY ASSESSMENT OF ANTIFUNGAL ACTIVITY OF SELECTED FUNGICIDES

Acta Scientiarum Polonorum: Hortorum Cultus, 2007
The antifungal activity of two fungicides, i.e. Rovral Flo 255 SC and Sportak Alpha 380 EC was determined by in vitro tests to 12 fungal species isolated from blue spruce (Picea pungens) and its cultivar Glauca.

Improvement of grafting procedures for the ornmental species: I. Picea pungens Engelm. var. glauca Regel [PDF]

Annals of Forest Research, 2011
In order to get ornamental trees for landscaping, Colorado blue spuce (Picea pungens Engelm. var. glauca Regel) scions were grafted on Norway spruce (Picea abies (L.) Karst.) rootstocks.An original double-side-veneer grafting method was applied in five ...
