摘要

Narrow heart-cut fractions of Cerro Negro and Wilmington crude oil acid- and base-free distillates were prepared on a preparative dinitroanilinopropylsilica (DNAP) column by a gradient solvent program. The fractions were characterized by synchronized scanning fluorimetry and gas chromatography/mass spectrometry. Average instrument response factors for ultraviolet spectroscopy and gas chromatography/flame ionization detection were determined on the heart-cut fractions. 3 figures, 4 tables. (ERA citation 10:019901)

5. Figure 3: (A) Constrained ordination (CAP; Resource and Fencing are the constraining factors) with vector overlays representing simple Spearman correlations between response variables and the two axes (Appendix S2). Separation of communities along Axis 1 is largely related to the impact of the Resource treatment on community structure. Thus, the extent to which a vector is parallel with Axis 1 reflects the extent of the negative (to the left) or positive (to the right) correlation of densities of that taxon with the addition of detritus. The length of each vector represents the joint correlation of the response variable with both axes of the ordination, with the circle representing a correlation of 1. Vectors shown have Spearman coefficients with CAP Axis 1 that are ≥.50 or ≤−.50. To prevent clutter on the graph, arrow heads of the vectors are not drawn. Key to abbreviations is in Fig. 1. (B) Constrained ordination (CAP) with vector overlays representing multiple correlation coefficients (analogous to univariate partial correlation coefficients). [O] . -1
