Comparative diversity of ammonia oxidizer 16S rRNA gene sequences in native, tilled, and successional soils
Contributor:Kowalchuk, George A.; Bruns, Mary Ann; Stephen, John R.; Paul, Eldor A.; Prosser, James I.
Autotrophic ammonia oxidizer (AAO) populations in soils from native, tilled, and successional treatments at the Kellogg Biological Station Long-Term Ecological Research site in southwestern Michigan were compared to assess ...
Isolation of saprophytic basidiomycetes from soil
Contributor:Harris, David; Thorn, R. Greg; Reddy, C. Adinarayana; Paul, Eldor A.
A method with the combined advantages of soil particle washing, selective inhibitors, and an indicator substrate was developed to isolate saprophytic basidiomycetes from soil. Organic particles were washed from soil and ...
History of flooding at Colorado State University (1902, 1938, 1951, 1992 and 1997)
Contributor:Charlie, Wayne A.
Newspaper reports, photos, rainfall, and damage estimates are presented for the floods of 1902, 1938, 1951 and 1997 which impacted the campus of what is now know as Colorado State University. The September 20 and 21, 1902 ...

Do olfactory cues mediate interactions between rodents on northern shortgrass prairie?
Contributor:Stapp, Paul; Van Horne, Beatrice
We counted captures of free-ranging deer mice (Peromyscus maniculatus) in odor-baited traps to determine whether deer mice use olfactory cues to detect and evade grasshopper mice (Onychomys leucogaster), a predator and ...
Soil resources, microbial activity, and primary production across an agricultural ecosystem
Contributor:Ellis, Boyd G.; Crum, James R.; Paul, Eldor A.; Klug, Michael J.; Klingensmith, Katherine M.; Robertson, G. Philip
The degree to which soil resource availability is linked to patterns of microbial activity and plant productivity within ecosystems has important consequences for our understanding of how ecosystems are structured and for ...
Continuous flow isotope ratio mass spectrometry of carbon dioxide trapped as strontium carbonate
Contributor:Paul, Eldor A.; Porter, L. K.; Harris, D.
The isotopic signal provided by differential discrimination against atmospheric carbon dioxide (13CO2) by C3 and C4 plant photosynthetic pathways is being widely used to study the processes of carbon (C) fixation, soil ...
Inertia in plant community structure : state changes after cessation of nutrient-enrichment stress
Contributor:Lauenroth W. K.; Milchunas, D. G.
Water, nitrogen, and water-plus-nitrogen at levels beyond the range normally experienced by shortgrass steppe communities were applied from 1971 through 1975, plant populations were sampled through 1977, and the results ...
Interactions between individual plant species and soil nutrient status in shortgrass steppe
Contributor:Burke, Ingrid C.; Vinton, Amry Ann
The effect of plant community structure on nutrient cycling is fundamental to our understanding of ecosystem function. We examined the importance of plant species and plant cover (i.e., plant covered microsites vs. bare ...
Thirty years after he laid the foundation for environmental ethics, Holmes Rolston continues to wrestle with one of the West's most contentious issues, bridging the human and the natural world. So revolutionary has Rolston's ...
