To burn or not to burn Oriental bittersweet: A fire manager’s conundrum
Noel B. Pavlovic, Stacey A. Leicht-Young, Krystal Frohnapple, Neal Mulconrey
2009, Report
Oriental bittersweet (Celastrus orbiculatus) is a highly invasive liana (woody vine) that occurs throughout the Eastern United States. This twining plant can blanket and girdle adjacent vegetation, affecting succession and damaging trees. In areas where prescribed fire is a management tool, the response of Oriental bittersweet to fire needs to...

Magma evolution and ascent at the craters of the moon and neighboring volcanic fields, southern Idaho, USA: Implications for the evolution of polygenetic and monogenetic volcanic fields
Keith D. Putirka, Mel A. Kuntz, Daniel M. Unruh, Nitin Vaid
2009, Journal of Petrology (50) 1639-1665
The evolution of polygenetic and monogenetic volcanic fields must reflect differences in magma processing during ascent. To assess their evolution we use thermobarometry and geochemistry to evaluate ascent paths for neighboring, nearly coeval volcanic fields in the Snake River Plain, in south-central Idaho, derived from (1) dominantly Holocene polygenetic evolved...
