Four Years of Epiphyte Colonization in Douglas-fir Forest Canopies
In 1995, we installed surface-sterilized, rough-barked and smooth-barked tree branches in clearcuts, young forests, and old growth. Half of the experimental branches were inoculated with propagules of the epiphytic cyanolichen, Lobaria oregana. In 1997, we concluded that L. oregana was associated with old-growth Douglas-fir forests because of dispersal limitation; addition of L. oregana propagu...

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...
متن کاملHigh titer and yield ethanol production from undetoxified whole slurry of Douglas-fir forest residue using pH profiling in SPORL
BACKGROUND Forest residue is one of the most cost-effective feedstock for biofuel production. It has relatively high bulk density and can be harvested year round, advantageous for reducing transportation cost and eliminating onsite storage. However, forest residues, especially those from softwood species, are highly recalcitrant to biochemical conversion. A severe pretreatment for removing this...
متن کاملRate 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 کاملNative forest pathogens facilitate persistence of Douglas-fir in old-growth forests of northwestern California
Forest pathogens and insects can accelerate tree mortality, increase stand structural heterogeneity, and alter tree community composition. In northern California, the canopy trees Abies concolor var. lowiana (Gord. & Glend.) Lemmon (white fir) and Pseudotsuga menziesii var. menziesii (Mirbel) Franco (Douglas-fir) co-occur but vary in shade tolerance and regenerative abilities following disturba...
