Rate of Respiration of Douglas-Fir Seedlings
The rate of photorespiration of Douglas-fir seedlings was measured under different light intensities by: (1) extrapolating the curve for CO., uptake in reilation to atmospheric CO, content to zero CO2, content, and (2) measuring CO, evolution of the plants into a CO2-free airstream. Different results, obtained from these techniques, were lelieved to be caused by 'a severe restriction of the pho...
متن کاملAdaptive significance of intermittent shoot growth in Douglas-fir seedlings.
We tested the hypothesis that intermittent (lammas) shoot growth in Douglas-fir (Pseudotsuga menziesii var menziesii (Mirb.) Franco) seedlings from dry regions of southwest Oregon is adaptively significant. Seedlings from open-pollinated families (160 total) from two inland (dry) and two coastal (wet) sources were grown under either well-watered or intermittent drought conditions (temporary dro...
متن کاملGenetic maladaptation of coastal Douglas-fir seedlings to future climates
Climates are expected to warm considerably over the next century, resulting in expectations that plant populations will not be adapted to future climates. We estimated the risk of maladaptation of current populations of coastal Douglas-fir (Pseudotsuga menziesii var. menziesii) to future climates as the proportion of nonoverlap between two normal distributions where the means and genetic varian...
متن کاملLocal adaptation in migrated interior Douglas-fir seedlings is mediated by ectomycorrhizas and other soil factors.
Separating edaphic impacts on tree distributions from those of climate and geography is notoriously difficult. Aboveground and belowground factors play important roles, and determining their relative contribution to tree success will greatly assist in refining predictive models and forestry strategies in a changing climate. In a common glasshouse, seedlings of interior Douglas-fir (Pseudotsuga ...

1Principal Entomologist and Project Leader (retired), Forestry Sciences Laboratory, USDA Forest Service, Moscow, ID; 2Forest Entomologist, USDA Forest Service, Forest Health Protection, Northern Region, Coeur d’Alene, ID. Douglas-fir beetle galleries are distinctive, having eggs laid individually in niches alternating on opposite sides of the gallery. The Douglas-fir beetle (Dendroctonus pseudo...
