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...

Abstract:

ABSTRACT Fumigants. Chioropicrin, Vapam and Vorlex continue to control Internal decay of Douglas-fir poles 11 years after application. Methylisothiocyanate (MIT), which was melted and poured into holes in Douglas-fir poles 3-years ago and goes directly from a solid to a gas in the wood, appears promising In controlling decay fungi....
