Fire severity in southwestern Colorado unaffected by spruce beetle outbreak,CU-Boulder study finds
Fire severity southwestern Colorado unaffected by spruce beetle CU-Boulder
2015/11/12
Contrary to expectations that spruce beetle infestations increase the severity of wildfires in southwestern Colorado, a new study led by University of Colorado Boulder researchers has found that this ...
Extracting a common high frequency signal from Northern Quebec black spruce tree-rings with a Bayesian hierarchical model
Northern Quebec black spruce tree-rings Bayesian hierarchical model
2009/12/3
One basic premise of dendroclimatology is that tree rings can be viewed as climate proxies, i.e. rings are assumed to contain some hidden information about past climate. From a statistical perspective...
Comparison of Simulated Water Balance for Willow,Spruce,Grass Ley and Barley
Simulated Water Balance Willow Spruce Grass Ley Barley
2009/10/23
Evaporation from four cropping systems, i.e. willow, spruce, grass ley and barley,
was compared in this simulation study. The physically based soil model had
prev~ously been used to simulate a wide ...
Simulation of Snowmelt in a Subarctic Spruce Woodland:Scale Considerations
Simulation of Snowmelt Subarctic Spruce Woodland Scale Considerations
2009/10/23
Subarctic woodlands comprise stands of spruce trees with varying degrees of
openness, giving rise to large contrasts in melt rates within the forest. The spatial
variability of the changing snow dep...
Interception of a Dense Spruce Forest,Performance of a Simplified Canopy Water Balance Model
Interception Dense Spruce Forest Water Balance Model
2009/10/22
The process of interception was studied in 25-year-old dense stands of Norway
spruce in South Sweden. The throughfall was measured intensively during one
month and extensively during four growing se...
Forest floor carbon exchange of a boreal black spruce forest in eastern North America
Forest floor carbon exchange boreal black spruce forest eastern North America
2010/1/21
This study reports continuous automated measurements of forest floor carbon (C) exchange over feathermoss, lichen, and sphagnum micro-sites in a black spruce forest in eastern North America during sno...
Relationships between spruce plantation age, solute and soil chemistry in Hafren forest
dissolved organic nitrogen Acid neutralizing capacity soil chemistry
2009/6/8
Rain, throughfall, soil waters from surface peaty O horizon and deeper mineral B horizon, and stream water, were collected every four weeks for one year in a moorland catchment, and in four forested c...
Assessing soil calcium depletion following growth and harvesting of Sitka spruce plantation forestry in the acid sensitive Welsh uplands
soil calcium depletion Welsh uplands plantation forestry
2009/6/5
A simple mass balance has been used to estimate soil calcium depletion during the growth of a 50 year old Sitka spruce crop on acid, base-poor peaty podzol soils in upland Wales. Growth of the crop wi...
Cycling of nutrient base cations in a twelve year old Sitka spruce plantation in upland mid-Wales
Forestry base cations
2009/3/24
The effects of the early growth of plantation forestry on the biogeochemical cycling of potassium, calcium and magnesium have been investigated in a stand of 12 year old Sitka spruce and adjacent moor...
The flux of carbonyl sulfide and carbon disulfide between the atmosphere and a spruce forest
flux of carbonyl sulfide carbon disulfide atmosphere spruce forest
2009/3/12
Turbulent fluxes of carbonyl sulfide (COS) and carbon disulfide (CS2) were measured over a spruce forest in Central Germany using the relaxed eddy accumulation (REA) technique. A REA sampler was devel...
The hydrochemistry of plantation spruce forest catchments with brown earth soils, Vyrnwy in mid-Wales
Gran alkalinity aluminium harvesting nutrients Vyrnwy water quality
2009/3/5
At Vyrnwy, in mid-Wales, a study of the hydrogeochemistry of two small spruce forested catchments, one a control and one felled midway through the study, shows a classic picture of rainfall inputs dam...
Effects of five years of frequent N additions, with or without acidity, on the growth and below-ground dynamics of a young Sitka spruce stand growing on an acid peat: implications for sustainability
acid canopy application nitrogen acid organic soil soil water young Sitka spruce
2009/3/5
A field manipulation study was established to demonstrate effects of simulated wet N and S deposition on a young (planted 1986) stand of Sitka spruce growing on a predominantly organic soil in an area...
Modeling carbon dynamics in two adjacent spruce forests with different soil conditions in Russia
carbon dynamics adjacent spruce forests soil conditions Russia
2010/1/18
Net ecosystem carbon exchange (NEE) was measured with eddy covariance method for two adjacent forests located at the southern boundary of European taiga in Russia in 1999–2004. The two spruce forests ...
