Methods and applications of HPLC-AMS (WBio 5)

Description: Pharmacokinetics of physiologic doses of nutrients, pesticides, and herbicides can easily be traced in humans using a {sup 14}C-labelled compound. Basic kinetics can be monitored in blood or urine by measuring the elevation in the {sup 14}C content above the control predose tissue and converting to equivalents of the parent compound. High Performance Liquid Chromatography (HPLC) is an excellent method for the chemical separation of complex mixtures whose profiles afford estimation of biochemica… more

Effects of Restoration Techniques on Breeding Birds in Thermally-Impacted Bottomland Hardwood Forests

Description: Breeding birds were studied in the Pen Branch riparian corridor following site preparation using herbicides and burning to control willow and improve access for planting. Compared with control strips, treated areas supported a greater richness and abundance of breeding birds. The community composition was representative of early successional bottomland forests.

Effects of Willow Overstory on Planted Seedlings in a Bottomland Restoration

Description: Various treatments were applied to control overstory willow in the riparian area of the Pen Branch system in order to determine the effects of competition control on seedling survival and growth. Four species, bald cypress, water tupelo, green ash, and swamp chestnut oak, were planted under four levels of willow canopy (intact, 60% removal, 100% removal with herbicide, 100% with mechanical). Species were more important in determining survival than treatment. Bald cypress and green ash survived … more

Quantitative and qualitative measures of decomposition: Is there a link?

Description: Decomposition rates of loblolly pine coarse woody debris (CWD) were determined by mass loss and wood density changes for trees that differed in source of mortality (natural, girdle-poison, and felling). Specifically, three treatments were examined: (1) control (CON): natural mortality; (2) CD: 5-fold increase in CWD compared with the CON; and (3) CS: 12-fold increase in snags compared with the CON. The additional CWD in the CD treatment plots and the additional snags in the CS plots were achiev… more

Multidisciplinary research program directed toward utilization of solar energy through bioconversion of renewable resources. Progress report

Description: Progress is reported in four research areas of solar bioconversion. The first program deals with the genetic selection of superior trees, physiological basis of vigor, tissue culture, haploid cell lines, and somatic hybridization. The second deals with the physiology of paraquat-induced oleoresin biogenesis. Separate abstracts were prepared for the other two program areas: biochemical basis of paraquat-induced oleoresin production in pines and biochemistry of methanogenesis. (JSR)

Harvester ant bioassay for assessing hazardous chemical waste sites. [Pogonomyrmex owhyeei]

Description: A technique was developed for using harvester ants, Pogonomyrmex owhyeei, in terrestrial bioassays. Procedures were developed for maintaining stock populations, handling ants, and exposing ants to toxic materials. Relative toxicities were determined by exposing ants to 10 different materials. These materials included three insecticides, Endrin, Aldrin, and Dieldrin; one herbicide, 2,4-D; three complex industrial waste residuals, wood preservative sludge, drilling fluid, and slop oil; and three … more

Biotechnology and Genetic Optimization of Fast-Growing Hardwoods

Description: A biotechnology research program was initiated to develop new clones of fast-growing Populus clones resistant to the herbicide glyphosate and resistant to the leaf-spot and canker disease caused by the fungus Septoria musiva. Glyphosate-resistant callus was selected from stem segments cultured in vitro on media supplemented with the herbicide. Plants were regenerated from the glyphosate-resistant callus tissue. A portion of plants reverted to a glyphosate susceptible phenotype during organogene… more

Kudzu (Pueraria montana) community responses to herbicides, burning, and high-density loblolly pine

Description: Kudzu is an aggressive, nonnative vine that currently dominates an estimated 810,000 ha of mesic forest communities in the eastern United States. To test an integrated method of weed control, abundances of kudzu and other plant species were compared during 4 yr after six herbicide treatments (clopyralid, triclopyr, metsulfuron, picloram 1 2,4-D, tebuthiuron, and a nonsprayed check), in which loblolly pines were planted at three densities (0, 1, and 4 seedlings m22) to induce competition and pot… more
