چکیده

Abstract Key message Growth sensitivity to climate varies with soil moisture regime in spruce–fir forests central British Columbia. Stands growing at their dry edaphic limits displayed especially strong and unique climatic sensitivities. Soil is an important influence of productivity, process, structure forested ecosystems. In western North America, projected warming trends may result decreasing available moisture; however, the potential effects on forest growth remain unclear. This study aimed determine stand-level mature hybrid white spruce ( Picea glauca (Moensch) Voss x engelmannii Parry) subalpine fir Abies lasiocarpa (Hook.) Nutt.) Columbia, Canada. We collected analyzed tree-ring data from 51 stands spanning a range regimes. Dendroecological analyses climate–growth relationships indicated that warm summer temperatures drought limit for both species across all regimes; responses were strongest driest sites. Spruce populations gradient regimes climate-growth relationships; wetter sites was more correlated year prior growth. Radial strengthened over past ca. 80 years most sites, suggesting are shifting this region. presents evidence importance considering site-level ecological factors such as when studying climate.

Harvesting and climate effects on organic matter characteristics in British Columbia coastal forests.

As part of investigations into the effects of harvesting old-growth forest, we characterized carbon in five organic matter pools in eight forest chronosequences of coastal British Columbia. Each chronosequence comprised stands in four seral stages from regeneration (3-8 yr) to old-growth (>250 yr), with second-growth stands mostly of harvest origin. Stands were located in two biogeoclimatic sub...

Soil Moisture Memory in Climate Models

Water balance considerations at the soil surface lead to an equation that relates the autocorrelation of soil moisture in climate models to 1) seasonality in the statistics of the atmospheric forcing, 2) the variation of evaporation with soil moisture, 3) the variation of runoff with soil moisture, and 4) correlation between the atmospheric forcing and antecedent soil moisture, as perhaps induc...

Historical climate controls soil respiration responses to current soil moisture.

Ecosystem carbon losses from soil microbial respiration are a key component of global carbon cycling, resulting in the transfer of 40-70 Pg carbon from soil to the atmosphere each year. Because these microbial processes can feed back to climate change, understanding respiration responses to environmental factors is necessary for improved projections. We focus on respiration responses to soil mo...

Some Slashburning Effects on Soil and Trees in British Columbia

Studies on slashburning effects in British Columbia have yielded a range ofresults. On some sites, fire effects on soil temperatures or competing vegetation may account for better tree growth on burned than unburned areas. In some cases, short-term effects on browse damage may temporarily obscure long-term effects on height growth. Slashburning effects on tree nutrient status vary between study...
