Tree seedling response to LED spectra: Implications for forest restoration

Publications Posted on: April 23, 2018
We found that different spectra, provided by light-emitting diodes or a fluorescent lamp, caused different photomorphological responses depending on tree seedling type (coniferous or broad-leaved), species, seedling development stage, and seedling fraction (shoot or root). For two conifers (Picea abies and Pinus sylvestris) soon after germination (≤40 days), more seedling growth was related to a lower ratio of red-to-far-red (R:FR) light.

Does clear-cut harvesting accelerate initial wood decomposition? A five-year study with standard wood material

Publications Posted on: June 07, 2016
Coarse woody debris (CWD) serves a variety of ecological functions in forests, and the understanding of its decomposition is needed for estimating changes in CWD-dependent forest biodiversity, and for the quantification of forest ecosystem carbon and nutrient pools and fluxes.

Redistribution of vegetation zones and populations of Larix sibirica Ledb. and Pinus sylvestris L. in central Siberia in a warming climate

Publications Posted on: May 12, 2016
Evidence for global warming over the past 200 years is overwhelming (Hulme et al. 1999), based on both direct weather observation and indirect physical and biological indicators such as retreating glaciers and snow/ice cover, increasing sea level, and longer growing seasons (IPCC 2001). Recent GCM projections of the Hadley Centre (Gordon et al.

Data product containing 20-year tree heights, diameters, and genetic variation for "Scots Pine in Eastern Nebraska: A Provenance Study"

Datasets Posted on: March 27, 2015
Seedling progenies of 36 rangewide provenances of Scots Pine (Pinus sylvetris) were established in a field test at Horning State Farm experimental area near Plattsmouth, Nebraska in April of 1962. Tree heights were measured at the end of each growing season from 1963 through 1969, and again in 1971. Tree height and diameter at breast height were both measured at the end of the growing season in 1976, 1978, 1979, and 1981.

Scotch pine for the northern Great Plains

Publications Posted on: September 29, 2006
A provenance test of 49 origins of Scotch pine (Pinus sylvestris L.) from eastern Europe, Russia, and Siberia was established at three locations in North Dakota and one in Nebraska. After 10 years (7 in Nebraska), trees from 50º to 55º latitude and 20º to 40º longitude survived best, were taller, and had greener winter foliage. Several provenances appear to be well suited for planting in shelterbelts and for Christmas tree culture.
