Abstract. Drought stress can cause xylem embolism in trees when the water potential (W)in the xylem falls below specific vulnerability thresholds. At the alpine timberline, frostdrought is known to cause excessive winter embolism unless xylem vulnerability ortranspiration is sufficiently reduced to...

Drought stress can cause xylem embolism in trees when the water potential (Psi) in the xylem falls below specific vulnerability thresholds. At the alpine timberline, frost drought is known to cause excessive winter embolism unless xylem vulnerability or transpiration is sufficiently reduced to...

Functional diversity is an important concept in community ecology because it captures information on functional traits absent in measures of species diversity. One popular method of measuring functional diversity is the dendrogram-based method, FD. To calculate FD, a variety of methodological...

Cumming, S. G., Schmiegelow, F. K. A., Burton, P. J.
Trembling aspen (Populus tremuloides) in western Canadian boreal forests is generally believed to occur as young, even-aged stands, as part of a fire-dominated landscape. However, the available quantitative estimates of the rate of disturbance by fire in this region differ markedly. One estimate...

Dhir, N., Rweyongeza, D., Yeh, F.
We estimated heritabilities and correlations for bud flushing and growth traits of white spruce seedlings, and the correlations of seedling traits with 10- and 11-year height of the same families in the field. The seedling greenhouse experiment had a randomized complete block design with 30...

Genetic variation in height, branch and needle lengths of Pinus sylvestris L. from Siberia tested in Alberta, Canada

Dhir, N.K., Rweyongeza, D., Yeh, F.C., Dancik, B.P.
We performed the analysis of variance and covariance on height, branch length, height to branch length ratio, and needle length measurements from thirty open-pollinated families of Pinus sylvestris L. from Siberia, Russia. This progeny trial was replicated on three sites in central Alberta,...

Genetic variation of hydraulic and wood anatomical traits in hybrid poplar and trembling aspen

Hacke, U.G., Schreiber, S.G., Hamann, A., Thomas, B.R.
•Intensive forestry systems and breeding programs often include either native aspen or hybrid poplar clones, and performance and trait evaluations are mostly made within these two groups. Here, we assessed how traits with potential adaptive value varied within and across these two plant groups....

This scientific commentary refers to `Negative effects of low root temperatures on water and carbon relations in temperate tree seedlings assessed by dual isotopic labelling' by Wang and Hoch (doi: 10.1093/treephys/tpac005). In his pioneering 1868 Lehrbuch der Botanik (Textbook on Botany) Julius...

Krachler, M., Fisher, D., Shotyk, W., Zheng, J.
Abstract: Despite its growing environmental significance, there are no detailed historical records of atmospheric As deposition for the Northern Hemisphere. Having overcome the severe analytical challenges in measuring As in polar ice, and using an Arctic ice core representing similar to 16 ka of...
