Effects of enhanced mid-ultraviolet radiation (290-315 NM) on development and survival of Boreal toad (Bufo boreas boreas) tadpoles

Creator:: Worrest, Robert C., 1935-
Abstract:: More than 3700 fertilized toad eggs were used in a series of studies designed to determine the effects of UV-B radiation (290- 315 nm) on temporal developmental patterns, systematic development and viability prior to metamorphic climax.

Response of estuarine diatom assemblages to ultraviolet-B radiation (290-320 nm)

Creator:: Brooker, Deborah L., Worrest, Robert C.,, and Oregon State University
Abstract:: Artificial substrates colonized by diatoms from Yaquina Estuary, Oregon, were exposed to solar visible radiation and three levels of ultraviolet radiation (UV-B, 290-320 nm). Flow-through microcosms were constructed inside a glasshouse to serve as chambers for the artificial substrates. The artificial substrates were sampled during three spring/summer experiments. Chlorophyll a...

Creator:: Elgin, Robert C., III
Abstract:: Given the current abundant supply and cheap price of natural gas (NG) in the United States, there is a significant opportunity to use this fuel for transportation. However, there are few fueling stations for consumers. To address this need, a dual-mode engine has been developed where in one mode all...
