Marketing Of Forest Reproductive Material: The Use Of Microsatellites For Identification Of Registered Tree Clones In Finland, Leena Koviuranta, Kari Leinonen, Pertti Pulkkinen

According to the current legislation on the marketing of forest reproductive material, tree clones marketed in the EU must have certain traits which make them identifiable, and these traits must have been accepted and registered by an official body. Due to this obligation, there is a need for reliable, functional and practicable methods for specifying these distinctive characters. We have developed a clone identification method for European and hybrid aspens and curly birch, based on nuclear microsatellites, which can be used for determining the distinctive characters mentioned in the directive. For aspens, we have used 18 loci, of which nine …
Gauging The Acceptability Of Fuels Management: A Matter Of Trust, Mark W. Brunson
Gauging The Acceptability Of Fuels Management: A Matter Of Trust, Mark W. Brunson

There is a significant gap between the acceptability of management practices in theory and the confidence that citizens have in land managers' abilities to use those practices safely and effectively. But since most citizens are willing to accept the use of multiple practices on a small scale, opportunities exist for land managers to build citizens’ confidence in their activities while gradually reducing the risk of wildfire to the Great Basin’s most susceptible communities.
N-Transfer Through Aspen Litter And Feather Moss Layers After Fertilization With Ammonium Nitrate And Urea, N A. Startsev, V J. Lieffers, S M. Landhausser, A Velazquez-Martinez
N-Transfer Through Aspen Litter And Feather Moss Layers After Fertilization With Ammonium Nitrate And Urea, N A. Startsev, V J. Lieffers, S M. Landhausser, A Velazquez-Martinez
Aspen Bibliography
When fertilizer is broadcast in boreal forest stands, the applied nutrients must pass through a thick layer of either feather moss or leaf litter which covers the forest floor. In a growth chamber experiment we tested the transfer of N through living feather moss or aspen litter when fertilized with urea ((NH2)2CO) or NH4NO3 at a rate of 100 kg ha−1 and under different watering regimes. When these organic substrates were frequently watered to excess they allowed the highest transfer of nutrients through, although 72% of the applied fertilizer was captured in the substrates. In a field experiment we also …
Does Moose Browsing Threaten European Aspen Regeneration In Koli National Park, Finland?, Sauli Harkonen, Kalle Eerikainen, Riikka Lahteenmaki, Risto Heikkila
Does Moose Browsing Threaten European Aspen Regeneration In Koli National Park, Finland?, Sauli Harkonen, Kalle Eerikainen, Riikka Lahteenmaki, Risto Heikkila
Aspen Bibliography
Large European aspen (Populus tremula) trees host hundreds of species of which many are threatened species of conifer-dominated, old-growth boreal forests. Aspen is also one of the deciduous tree species most intensively used by moose (Alces alces) in Finland. In conservation areas aspen regeneration is facilitated by large-scale disturbances, especially fires and windstorms, and also by mortality of individual trees and small-scale disturbances that create small openings. These aggregated patches of young aspens provide high quality feeding sites for moose. In Finland, it has been hypothesized that intense browsing pressure by moose on aspen may prevent new aspen cohorts from …
