Previous research examining the influences of post-fire salvage logging on abundances of birds has focused primarily on the response of cavity-nesting species. There is limited research in regard to the impact of salvage logging on a broader range of bird species. In addition, little is known about how different intensities...

Previous research examining the influences of post-fire
I monitored demography, movement, and reproductive behavior of gray-tailed voles, Microtus canicaudus, in experimental habitat patches with and without corridors. I tested the hypotheses that reproductive rate, juvenile recruitment, and population size and growth rate would be affected negatively by immigrants that were introduced to resident groups (+ male and...
Selected parameters that affect crude toxin production in both
primary culture (growing cell culture) and resting culture were
examined during efforts to produce sufficient crude toxin for purification.
The parameters included carbohydrate and label source and
concentration, cell concentration, incubation time and temperature
and shaker speed. A higher yield of...
The effects of light incident on leafy cuttings is
quite complex because' light influences several factors
which may affect root formation. One effect of light is
to influence the carbohydrate status of the cutting by
influencing photosynthesis. The role of current photosynthate
in the rooting of leafy cuttings is uncertain....
Thirteen healthy adult males, ages 20-40, consuming self selected
diets, were given instructions to take one 500 mg tablet of ascorbic
acid three times a day with their meals for a period of ten weeks. The
effect of this daily supplementation on copper status was investigated.
An estimation made from...
The Goose Lake Basin, situated on the border of Oregon and California, USA, faces significant challenges from drought, wildfire, and other environmental stressors. This region hosts numerous endemic fish species such as the Goose Lake redband trout (Oncorhynchus mykiss newberri), Goose Lake lamprey (Entosphenus sp.), Goose Lake tui chub (Siphateles...
Products as diverse as soda-pop, fashion and
automobiles are selling to the tunes of classic and current
pop and rock music. The combination of MTV (Music
Television), the latest audio-visual technology, and the
replacement of movie stars by rock stars as the idols of
contemporary youth (Beckett, 1985; Hartman, 1987),...
A major challenge to the study of the peopling of the Americas is that much of the Bering Land Bridge (Beringia), the geographic area that people migrating from Northeast Asia into North America would presumably have passed through, is now submerged due to sea-level rise since the last glacial maximum....
An evaluation of the service time of an activated carbon adsorption
column and the organic carbon removal efficiency treating activated
sludge process effluent was completed at aerator detention
times of three, five, and ten hours. Parameters used for evaluation
of treatment were biochemical oxygen demand, chemical oxygen
demand, total organic...
