Recovering Lost Ground : Effects of Soil Burn Intensity on Nutrients and Ectomycorrhiza Communities of Ponderosa Pine Seedlings

Creator:: Cowan, Ariel D.
Abstract:: Fuel accumulation and climate shifts are predicted to increase the frequency of high-severity fires in ponderosa pine (Pinus ponderosa Dougl. ex Laws) forests of central Oregon. The combustion of fuels containing large downed wood can result in intense soil heating, alteration of soil properties, and mortality of microbes. Previous studies...

The biologies of predators (Coleoptera: Cleridae) of the Douglas-fir beetle, Dendroctonus pseudotsugae Hopkins (Coleoptera : Scolytidae), in western Oregon

Creator:: Cowan, Bruce Dudley
Abstract:: Six species of Cleridae, including Enoclerus spegeus Fabricius, E. lecontei Wolcott, E. schaefferi (Barr), E. eximius Mannerheim, Thanasimus undatulus Say, and an undescribed species of Enoclerus, were found on Douglas-fir in western Oregon. E. sphegeus was the only clerid of the six species studied which was primarily associated with the...

A comparison of plant characteristics of annual ryegrass (Oregon), Lolium multiflorum Lam., and Linn perennial ryegrass, Lolium perenne L.

Creator:: Rosell, C. H.
Abstract:: Studies were conducted to establish some characters which could be used, either in the field or in the laboratory, to differentiate between annual ryegrass (Oregon), Lolium multiflorum Lam. , and Linn perennial ryegrass, Lolium perenne L. Vernation, percentage of glumes covering the spikelets, and height of seedlings seem to be...

Effects of fuel content and density on the smoldering characteristics of cellulose and hemicellulose

Creator:: Smucker, Benjamin D., Mulky, Tejas C., Cowan, Daniel A., Niemeyer, Kyle E., and Blunck, David L.
Abstract:: Smoldering combustion in wildland fires poses hazards for both ecosystems and humans by destroying biomass, transitioning to flaming combustion, and releasing significant quantities of pollution. Understanding the parameters that control smoldering is necessary to help predict and potentially mitigate these hazards. A challenge in identifying these parameters is the wide...

The size of the chromosome segment transduced by phage Pl.

Creator:: Cowan, Judith Harmon Miller
Abstract:: The purpose of this research was to determine whether the transducing phage Pl picks up original bacterial chromosome segments and whether these segments are always the same size. The plan of approach was to grow the donor bacteria Escherichia coli C600 gal⁺ (galactose) in minimal media containing the heavy isotopes...

A comparison of four methods of sampling small seeds

Creator:: Grisez, John Patrick
Abstract:: Sampling studies were conducted to compare the efficiency of the four officially recommended methods of sampling small seeds: automatic sampling--at two sampling speeds, hand sampling, Nobbe tier sampling, and stick trier sampling. Synthetic lots of orchard-grass, ryegrass, Kentucky bluegrass, and alfalfa seed were prepared containing known numbers of the common...

Recovering lost ground: Effects of soil burn intensity on nutrients and ectomycorrhiza communities of ponderosa pine seedlings

Creator:: Cowan, Ariel D., Smith, Jane E., and Fitzgerald, Stephen A.
Abstract:: Fuel accumulation and climate shifts are predicted to increase the frequency of high-severity fires in pon-derosa pine (Pinus ponderosa) forests of central Oregon. The combustion of fuels containing large downedwood can result in intense soil heating, alteration of soil properties, and mortality of microbes. Previousstudies show ectomycorrhizal fungi (EMF) improve...
