| deposition and retention of 141ce and 134cs aerosols on cool desert vegetation. | deposition velocities and retention times were obtained for submicron aerosols of 141ce and 13l4cs deposited on two cool desert plant species, big sagebrush (artemisia tridentata) and bottlebrush grass (sitanion hystrix). mean deposition velocities for sagebrush were 0.18 cm/s (141ce) and 0.13 cm/s (134cs). mean deposition velocities for grass were 0.022 (141ce) and 0.023 cm/s (134cs). species differences were significant (p less than 0.05), however, nuclide differences were not significant. the ... | 1983 | 6841091 |
| variability in thermal response of primed and non-primed seeds of squirreltail [elymus elymoides (raf.) swezey and elymus multisetus (j. g. smith) m. e. jones]. | bottlebrush squirreltail [elymus elymoides (raf.) swezey = sitanion hystrix (nutt.) j. g. smith] and big squirrel-tail [elymus multisetus (j. g. smith) m. e. jones = sitanion jubatum (j. g. smith)] have a broad geographical distribution and have been identified as high priority species for restoration of degraded rangelands in the western united states. these rangelands exhibit high annual and seasonal variability in seedbed microclimate. the objective of this study was to examine variability in ... | 2002 | 12096743 |
