Spring ephemeral herbs and nitrogen cycling in a northern hardwood forest: an experimental test of the vernal dam hypothesis
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 2000-08)
In the late 1970s R.N. Muller and F.H. Bormann posited their ”vernal dam” hypothesis, stating that spring-ephemeral herbs in deciduous forests serve as a temporary sink for N when overstory trees are dormant, and then ...
Performance of a generalist grasshopper on a C 3 and a C 4 grass: compensation for the effects of elevated CO 2 on plant nutritional quality
(Springer-Verlag, 2004-06)
The increasing CO 2 concentration in Earth’s atmosphere is expected to cause a greater decline in the nutritional quality of C 3 than C 4 plants. As a compensatory response, herbivorous insects may increase their feeding ...
Analysis of the Late Steps of Exocytosis: Biochemical and Total Internal Reflection Fluorescence Microscopy (TIRFM) Studies
(Kluwer Academic Publishers-Plenum Publishers; Springer Science+Business Media, Inc., 2006-04-20)
1. Time with Julie in his laboratory at the NIH in the early 1970s is remembered. The experience led to a life-long interest in the regulation of catecholamine secretion. Here are summarized aspects of this work.
Letter to the Editor: The C-terminal Domain of Viral IAP Associated Factor (cVIAF) is a Structural Homologue of Phosducin: Resonance Assignments and Secondary Structure of the C-Terminal Domain of VIAF

Generation of Phenylpropanoid Pathway-Derived Volatiles in Transgenic Plants: Rose Alcohol Acetyltransferase Produces Phenylethyl Acetate and Benzyl Acetate in Petunia Flowers
(Kluwer Academic Publishers; Springer, 2006-03)
Esters are important contributors to the aroma of numerous flowers and fruits. Acetate esters such as geranyl acetate, phenylethyl acetate and benzyl acetate are generated as a result of the action of alcohol acetyltransferases ...
Fungal community composition and metabolism under elevated CO 2 and O 3
(Springer-Verlag, 2006-02)
Atmospheric CO 2 and O 3 concentrations are increasing due to human activity and both trace gases have the potential to alter C cycling in forest ecosystems. Because soil microorganisms depend on plant litter as a source ...
Peptide F (pro-enkephalin fragment) : Radioimmunoassay, and stress-induced changes in adrenal
(Elsevier, 2006-04-07)
Utilizing a nine amino-acid (Asp-Glu-Leu-Tyr-Pro-Leu-Glu-Val-Glu) non-enkephalin containing fragment of Peptide F from the pro-enkephalin molecule, a radioimmunoassay was developed. Extraction of bovine, rat, and guinea ...
Coastal eutrophication assessment in the United States
(Kluwer Academic Publishers; Springer Science+Business Media, Inc., 2006-04-21)
Recent national assessments document that nitrogen-driven coastal eutrophication is widespread and increasing in the United States. This significant coastal pollution problem includes impacts including increased areas and ...
Evolution of N-terminal sequences of the vertebrate HOXA13 protein
(Springer-Verlag; Springer-Verlag New York Inc., 2000-02)
While the the role of the homeodomain in HOX function has been evaluated extensively, little attention has been given to the non-homeodomain portions of the HOX proteins. To investigate the evolution of the HOXA13 protein ...
Testing a simple stochastic model for the dynamics of waterfowl aggregations
(Springer-Verlag, 2001-08)
We consider a simple stochastic model for the dynamics of mixed-species waterfowl aggregations and describe two methods for assessing the fit of this model to field data. The model does not incorporate species-specific ...
