Scale and strength oak-mesophyte interactions in a transitional oak-hickory forest.

Can J For Res 2018 Nov 29;48(11):1366-1372. Epub 2018 Aug 29.

Department of Ecology and Evolutionary Biology, University of Michigan, Ann Arbor, MI 48109.

Forests in eastern North America are undergoing rapid compositional changes as they experience novel climate, disturbance, and pest conditions. One striking pattern is the replacement of canopy oaks spp.) by mesic, fire-sensitive, shade-tolerant species like red maple . Read More

Jiann C Yang

Can J For Res 2018 Jan 8;48(1):105-110. Epub 2017 Nov 8.

Fire Research Division, Engineering Laboratory, National Institute of Standards and Technology, Gaithersburg, Maryland 20899 U.S.A.

A dimensional analysis was performed to correlate the fuel bed fire rate of spread data previously reported in the literature. Under wind condition, six pertinent dimensionless groups were identified, namely dimensionless fire spread rate, dimensionless fuel particle size, fuel moisture content, dimensionless fuel bed depth or dimensionless fuel loading density, dimensionless wind speed, and angle of inclination of fuel bed. Under no-wind condition, five similar dimensionless groups resulted. Read More

Age-dependent climate-growth relationships and regeneration of in a drought-prone mixed coniferous forest in the Alps.

Can J For Res 2013 May;43(7):609-618

Leopold-Franzens-University of Innsbruck, Institute of Botany, Sternwartestrasse 15, A-6020 Innsbruck, Austria.

Within dry inner Alpine environments climate warming is expected to affect the development of forest ecosystems by changing species composition and inducing shifts in forest distribution. By applying dendroecological techniques we evaluated climate sensitivity of radial growth and establishment of in a drought-prone mixed-coniferous forest in the Austrian Alps. Time series of annual increments were developed from > 220 trees and assigned to four age classes. Read More

Temporal dynamics of non-structural carbohydrates and xylem growth in Pinus sylvestris exposed to drought.

Can J For Res 2011 Aug;41(8):1590-1597

Leopold-Franzens-University of Innsbruck, Institute of Botany, Sternwartestrasse 15, A-6020 Innsbruck, Austria.

Wood formation requires a continuous supply of carbohydrates for structural growth and metabolism. In the montane belt of the central Austrian Alps we monitored the temporal dynamics of xylem growth and non-structural carbohydrates (NSC) in stem sapwood of Pinus sylvestris L. during the growing season 2009, which was characterized by exceptional soil dryness within the study area.

Effects of shade and root confinement on the expression of plagiotropic growth in juvenile-origin Douglas-fir rooted cuttings.

Can J For Res 1997 Jul;27(7):1142-5

The George R. Staebler Forest Resources Research Center, Weyerhaeuser Company, Centralia, WA 98531, USA.

The purpose of this experiment was to determine why juvenile-origin Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) rooted cuttings, which remain plagiotropic (branchlike) when grown in containers in shaded glasshouses, become orthotropic (vertical) after they are transplanted to an outdoor environment. Plagiotropic rooted cuttings (mean angle from vertical = 45-50 degrees) from three full-sib families were transplanted into an outdoor nursery and subjected to four treatments consisting of a factorial of (1) shaded or unshaded and (2) bareroot or confined roots.
