The merits of fertilizing warmwater fish ponds with dry organic manure were studied from October, 1964 to November, 1965 using two experimental ponds in the Willamette Valley. One pond (pond II) was fertilized with urea and single superphosphate and the other (pond III) was fertilized with dried manure as well...
Diclofop (2- [4 -(2, 4-dichlorophenoxy)phenoxy] propanoic
acid), formulated as the methyl ester, selectively kills
barnyardgrass [Echinochloa crus -galli (L.) Beauv.] in several
crops when applied postemergence. Studies were conducted
to determine the effect of soil moisture, barnyardgrass age, and site of exposure on control of barnyardgrass with diclofop. Soil moisture...
Zoos, aquariums and other free-choice/informal education settings offer the public opportunities to interact with live animals in exhibits through animal encounters and/or touch experiences designed to carry a conservation mission. Many of these institutions are accredited by the American Association of Zoos and Aquariums (AZA) and the World Association of...
Community science (also called citizen science) has become an increasingly popular data collection technique for scientists researching nature at a large scale. Many ecologists have also looked to community science as a method for educating the public about science. Over the past several decades, researchers have attempted to define an...

Abstract
Community science (also called citizen science
The primary objective of this thesis is to study, characterize
and compare four types of Scenedesmus obliquus pigment mutants with
the wild-type strain. The specific nature of the carotenoids synthesized
in both heterotrophically and myxotrophically-grown cells, Hill
reaction activity, photoreduction activity, and total photosynthetic
activity of these cells are examined....
Courtship and copulation behaviors in Drosophila melanogaster males are regulated by sex-specific products from the gene fruitless (fru). Male-specific FRU proteins (FRU[superscript M]) are putative transcription factors of the BTB-ZnF family that likely act by controlling development and maintenance of the neural circuitry used during male sexual behavior. However, which...
