The effects of site and stand factors on the tree and wood quality of Sitka spruce growing in the United Kingdom

Autor: Moore, John, Lyon, Andrew, Searles, Gregory, Vihermaa, Leena

Publikováno v: Silva Fennica, Vol 43, Iss 3 (2009)

The extent and sources of variation in the wood quality of Sitka spruce (Picea sitchensis (Bong.) Carr.) were quantified using data collected from 64 stands in northern Britain. These stands were selected on the basis of elevation, latitude, longitud

Quantifying precision and accuracy of measurements of dissolved inorganic carbon stable isotopic composition using continuous-flow isotope-ratio mass spectrometry

Autor: Waldron, Susan, Scott, E. Marian, Vihermaa, Leena E., Newton, Jason

Publikováno v: Rapid Communications in Mass Spectrometry

RATIONALE:\ud We describe an analytical procedure that allows sample collection and measurement of carbon isotopic composition (δ13CV-PDB value) and dissolved inorganic carbon concentration, [DIC], in aqueous samples without further manipulation pos

Hydraulics are a first order control on CO2 efflux from fluvial systems

Autor: Long, Hazel, Vihermaa, Leena, Waldron, Susan, Hoey, Trevor, Quemin, Simon, Newton, Jason

Evasion of carbon dioxide (CO2) from fluvial systems is now recognized as a significant component of the global carbon cycle. However the magnitude of, and controls on, this flux remain uncertain and improved understanding of both are required to ref

Dissertation/ Thesis

Influence of site factors and climate on timber properties of Sitka spruce (Picea sitchensis (Bong.) Carr.)

Autor: Vihermaa, Leena

In plantation grown Sitka spruce, timber density is an important quality concern. Currently Sitka spruce timber meets the requirements for C16 strength grading which is the minimum requirement for construction uses. However, the margin is not exceede
