Higher soil moisture resulting from the inhibition of evapotranspiration lowered soil solution concentrations of p-coumaric acid by 14-40% but did not significantly influence the inhibitory effects of p-coumaric acid on seedlings. Inhibition of evapotranspiration and total leaf area and increases in lowest daily soil water were observed 1-3 d after the first p-coumaric acid treatment, whereas inhibition of absolute and relative rates of leaf expansion was observed within a 24-hr period. Development of the maximum effects of p-coumaric acid required several additional days. Recovery from effects, i.e., return to control levels, after p-coumaric acid depletion from soil solution was a gradual process requiring days for evapotranspiration, lowest daily soil water, and total leaf area, but was slightly faster for leaf area expansion. It appears, at least for short-term studies, that the initial input or treatment concentrations of p-coumaric acid represented a reasonable estimate of dose despite the dynamic nature of soil solution concentrations, and that the lowering of available p-coumaric acid concentrations, associated with the elevation of soil moisture, did not result in a concurrent detectable seedling response. However, increased soil moisture associated with p-coumaric acid treatments of sensitive species suggests a means by which the magnitude of some allelopathic interactions may be modified and resource competition and allelopathy could interact.}, number={8}, journal={JOURNAL OF CHEMICAL ECOLOGY}, author={Blum, Udo and Gerig, Thomas M.}, year={2006}, month={Aug}, pages={1817–1834} }
 @article{blum_gerig_2005, title={Relationships between phenolic acid concentrations, transpiration, water utilization, leaf area expansion, and uptake of phenolic acids: Nutrient culture studies}, volume={31}, ISSN={["0098-0331"]}, DOI={10.1007/s10886-005-5934-5}, abstractNote={Phenolic acid treatments of cucumber seedlings (Cucumis sativus cv "Early Green Cluster") inhibited transpiration, water utilization, leaf area, and absolute and relative rates of leaf expansion. The cinnamic acids, ferulic and p-coumaric acids, were two to five times more inhibitory than the benzoic acids, p-hydroxybenzoic acid and vanillic acid. When phenolic acid concentrations were maintained at inhibitory concentrations through multiple successive treatments, percent inhibition of water utilization remained relatively constant for a given concentration and phenolic acid, percent inhibition of leaf area initially increased and then leveled off to a constant percent, and percent inhibition of transpiration and rates of leaf area expansion declined over time. Subsequently, p-coumaric acid was chosen as the model compound for further study. When p-coumaric acid was inhibitory, percent inhibition of transpiration, water utilization, and rates of leaf area expansion of actively growing leaves rapidly declined (i.e., was lost) as p-coumaric acid concentrations surrounding roots decreased. Absolute and relative rates of leaf expansion, for example, declined approximately 12 and 14%, respectively, for every 0.1 mM decline in p-coumaric acid concentration. Uptake of p-coumaric acid by cucumber seedling roots was continuous over the 24- or 36-hr periods monitored, but was not consistently related to the initial p-coumaric acid treatment concentrations. However, declining p-coumaric acid concentrations monitored at 6- or 12-hr intervals over the 24- or 36-hr periods continued to be highly correlated to the initial p-coumaric acid treatment concentrations. A 25% depletion by 1 3-d-old cucumber seedlings took 8.5, 12, 19.5, 25, and 29.5 hr for 0.125-, 0.25-, 0.5-, 0.75-, and 1-mM treatments, respectively. Uptake during periods when phenolic acid concentrations and root uptake (depletion from solution) were related appeared to represent periods dominated by apoplastic movement into the intercellular spaces of roots. Uptake during periods without this relationship likely represented periods dominated by symplastic movement. The ability of cucumber seedlings to modify active phenolic acid concentrations surrounding their roots suggests that cucumber seedling can directly influence the magnitude of primary and secondary effects of phenolic acids through feedback regulation.}, number={8}, journal={JOURNAL OF CHEMICAL ECOLOGY}, author={Blum, U and Gerig, TM}, year={2005}, month={Aug}, pages={1907–1932} }

The objective was to identify hatchery- and transportation-associated risk factors for poult mortality in the first 14 d after placement using statistical models. Logistic regression was used to determine the effects of hatchery-and transportation-related factors on odds of mortality for hen and tom flocks separately. Hatchery and transportation-related risk factors for hen flock mortality included truck, truck temperature, and number of poults dead on arrival at the farm. Hatchery and transportation-related risk factors for tom flock mortality included desnooding, truck, truck temperature, shipping time, and weather conditions at placement.}, number={12}, journal={POULTRY SCIENCE}, author={Carver, DK and Fetrow, J and Gerig, T and Krueger, KK and Barnes, HJ}, year={2002}, month={Dec}, pages={1818–1825} }

Mortality patterns were not different for hen and tom flocks, although toms experienced greater mortality. Season of placement, breeder flock age, strain, hatchery, and company had significant effects on risk of poult mortality in the first 14 days after placement. Hen flocks hatched in Virginia or placed in summer had higher risks of mortality. Tom flocks from young breeder hens, hatched in Virginia, or placed in winter had higher risks of mortality. There were strain effects on risk for poult mortality, and effect of breeder flock age on poult mortality was strain specific for hen poults. Median mortality differences among companies ranged from 0.98 to 2.11% at Day 14 for hens, and from 1.27 to 5.76% at Day 14 for toms. There were wide-ranging company effects on risks of mortality.}, number={3}, journal={Journal of Applied Poultry Research}, author={Carver, D. K. and Fetrow, J. and Gerig, T. and Correa, M.

Nineteen dogs were evaluable for toxicity. Dose‐limiting gastrointestinal toxicosis was observed in three dogs, neutropenia was observed in three dogs, and cardiomyopathy was observed in three dogs.
