TL;DR: A new packrat midden chronology from Playas Valley, southwestern New Mexico, is the first installment of an ongoing effort to reconstruct paleovegetation and paleoclimate in the U.S.A. Borderlands as discussed by the authors.

TL;DR: Diurnal effects were not found to be important sources of error for chemosystematics in J. scopulorum if character weighting were used to maximize the genotype differences, however, this may not be true for work involving population sampling of other species over large regions.
Abstract: The volatile oils of four trees of Juniperus scopulorum were examined at 9 am, 12 noon, 3 pm, 6 pm, 10 pm, 2 am, and 6 am on consecutive days with a temperature range of 64 F and 88.5 F daily. Three-way analysis of variance of 37 compounds revealed 36 with significant differences among trees, 11 with significant differences between days, 13 compounds with significant diurnal variation and 9 compounds which showed some significant interaction term differences. Most of the variation occurred among trees. Oxygenated terpenes and sesquiterpenes tended to increase during the day while sabinene decreased until late evening and increased during the early morning. Correlations with temperature appeared to lag and did not match the pattern in three species of Juniperus reported by other investigators. The effect of diurnal variations on chemosystematic classifications was estimated by using numerical taxonomy and principal coordinate analysis. Diurnal effects were not found to be important sources of error for chemosystematics in J. scopulorum if character weighting were used to maximize the genotype differences. However, this may not be true for work involving population sampling of other species over large regions.
