In 1992, an unusual piece of vesicular material with a recoverable mass of 3 kg was unearthed from a field near the lawn of Granada. Colorado. The material was analyzed using petrological and geochemical methods, which included: bulk and trace...
Two subspecies of Black Rail (Laterallus jamaicensis) occur in the United States, and neither has been studied extensively. Of the two, the Eastern subspecies (L.j. jamaicensis) has a larger range, but has been studied to a lesser degree than the...
Vegetational composition and the origin of surface water were studied during 2007 and 2008 at two small (<3 ha) wetlands in Ellis County in west central Kansas. Methods used to analyze plant community composition included line transects, point...
Invasion by nonnative plants is particularly prevalent in wetlands. While the ecological patterns in wetland plants are well known, it is less well known how flooding-related soil conditions influence the physiological success of introduced species...
The Owyhee Basalt is a multi-flow unit of calc-alkaline lavas ranging in composition from basaltic andesite to andesite. The basaltic andesite are relatively primitive (Mg # > 50) and show a general trend of increasing SiO2 with decreasing age. ...
Understanding the role of an organism in an ecosystem involves understanding different aspects of their ecology, which is particularly true for species that are in danger of extinction due to habitat loss and fragmentation. The losses of amphibians...
Radon is a naturally occurring inert gas produced by the radioactive decay of uranium. Uranium is found in nearly all types of rocks and sediments. Radon-222 (Rn222), the most common isotope of radon, has a half-life of four days. The health risk...
A kinetic investigation has been made of the deiodination of o-iodoaniline in aqueous media. This has confirmed the mechanistic picture of the deiodination process proposed by H.S. Choguill and J.H. Ridd in J. Chem. Soc., 822 (1961), and also has...
