From animals to ecosystem processes: Predicting functional outcomes of climate-driven changes in animal communities through species traits
Functional trait diversity within species assemblages ultimately determines whether or not ecosystem processes are sensitive to shifts in relative abundances or species composition. For example, trait variation suggests detritivores process detritus at different rates and make different relative con
Impacts of assisted migration: An introduced herbivore has short-term and long-term effects on its native host plant population
Abstract Assisted migration consists of the introduction of a species to previously inhabited areas or to new suitable regions. Such introductions have been touted as a viable tool for conserving the earth's biodiversity. However, both the likely success of assisted migrations and the impacts on loc
Behavioral response of mountain white-crowned sparrows towards an interspecific competitor.
This study examined interspecific competition between mountain white-crowned sparrows (Zonotrichia leucophrys oriantha) and Lincoln’s sparrows (Melospiza lincolnii) using a playback experiment. Mountain white-crowned sparrow males were presented with three different song playback factors: 1) a negat
A Spatial Distribution Of Adult Obesity Prevalence In Denver County, Colorado: An Empirical Bayes Approach
Temporal variation in pollen limitation in Hydrophyllum fendleri (Boraginaceae) Individuals.
Plant reproduction is highly dependent upon phenology, or biological timing, of flowering. However, little is known about how individuals vary in their flowering schedules relative to the population as a whole or how this variation could lead to differences in reproductive success of individuals. He
Migration and population dynamics of hummingbirds
An investigation into the effects of arbuscular mycorrhizal fungi (AMF) to dark septate endophytes (DSE) ratio on the coarse root to fine root ratio at varying elevation in the rocky mountains
Belowground systems are crucial for sustaining ecosystem function, but often remain unseen. Not very much is known about these systems and improving knowledge of them can aid understanding of ecosystems. Elevational gradients can be good places to test how above- and belowground systems respond to c
Control of Colorado Potato Beetle with Natural Product Insecticides, Grand Forks, 1990
Abstract Natural product insecticides used in this experiment were Bacillus thuringiensis var. san diego (MYX 1806), B. thuringiensis var. tenebrionis (Trident and BK-102) and azadirachtin (Margosan-O) from the neem tree, Azadirachta indica. Plots were planted 15 May at the Research Farm, Red River

Polymorphism for pollen color of <i>Erythronium grandiflorum</i>
Sensitivity analysis of hydraulic conductivity and Manning’s n parameters lead to new method to scale effective hydraulic conductivity across model resolutions.
Hydrological modeling is an important tool for research, policy, and management, but uncertainty remains about parameters transferability from field observations made at small scale to models at the catchment scale and larger. This uncertainty compels the need to develop parameter relationships that
<i>The Economic Basis of Tax Reform</i>. By Harry Gunnison Brown.
Holarctic marmots as a factor of biodiversity
Circadian rhythms of body temperature were evident during deep torpor in 11 of 12 individuals. The mean period was 23.94 hours. Circadian cycles of oxygen consumption were apparent in Jive of 14 marmots. Arousal tended to occur during the increase phase of the cycle. This report may be the Jirst to
Annual seed catalog. garden, field and grass seeds. Season 1917
SEED TRADE have conditions been so complicated as they are today.The greatest of all wars has been raging for the past two and one-half years, and the end is as far off, apparently, as it was two years ago.The countries that have supplied us with the bulk of our seeds in the past are engaged in a de
