Mutant Weeds Of Iowa: S-Triazine-Resistant Plastids Chenopodium Album L., Jack Dekker, Ronald Burmester
Mutant Weeds Of Iowa: S-Triazine-Resistant Plastids Chenopodium Album L., Jack Dekker, Ronald Burmester
Journal of the Iowa Academy of Science: JIAS
S-triazine resistance in common lambsquarters (Chenopodium album L.) has been reported previously but not in Iowa. A study was conducted using a chlorophyll a fluorescence assay to confirm the presence of resistance in C. album populations in Iowa. Variable chlorophyll a fluorescence assays confirmed that mutations conferring resistance exist in five (5) geographically separated populations of C. album in Iowa: relatively greater fluorescence yields were measured in untreated resistant tissue compared with untreated susceptible plants, relatively greater fluorescence yield in treated compared with untreated susceptible leaf disks; and similar fluorescence yields of treated and untreated resistant tissue. This is the …

Ada Hayden: A Tribute, Duane Isely
Ada Hayden: A Tribute, Duane Isely
Journal of the Iowa Academy of Science: JIAS
Dr. Ada Hayden was a member of the Iowa State College of Botany faculty, 1920-1950. Her floristic studies of the lake region in northern Iowa are possibly the most authoritative for any part of the state. Hayden was curator of the Iowa State herbarium, 1934-1950, and contributed immeasurably to its development. This research facility has recently been named the Ada Hayden Herbarium. In the sense that L. H. Pammel was father of the Iowa State park system, her bequest is the state preserves. After some 25 years as a conservation activist, she published descriptions of 22 prairie areas in ten …
Ecology Of Iowa Drosophila Ii. Lowland Forest And Sand Prairie, Neil J. Jennings, Robert D. Seager
Ecology Of Iowa Drosophila Ii. Lowland Forest And Sand Prairie, Neil J. Jennings, Robert D. Seager
Journal of the Iowa Academy of Science: JIAS
The seasonal abundances of Drosophila species collected from a lowland forest community and from a sand prairie community in northeastern Iowa are compared. With some important exceptions, the patterns seen in the lowland forest community were similar to what had been observed in a previous collection (Jennings et al. 1985). Fewer species and many fewer individuals were collected from the sand prairie community, although in general the patterns seen were similar to those of the lowland forest community. Strong evidence of microhabitat differentiation was seen in both communities. In contrast to our previous study, none of the seasonal abundance patterns …

Effects Of New Science Textbooks On Selected Sixth And Eighth Grade Students At Crestwood Elementary School, Paris, Illinois, David R. Pruim
Effects Of New Science Textbooks On Selected Sixth And Eighth Grade Students At Crestwood Elementary School, Paris, Illinois, David R. Pruim
Masters Theses
This paper describes the results of a six-month field study to determine the effects of a newly adopted and implemented junior-high level science textbook series on student achievement. This study took place in the sixth, seventh, and eighth grade science classrooms of Crestwood Elementary School, Paris, Illinois, from December 1988, until May of 1989. This study compared the science achievement of two groups of students in both their sixth and eighth grade years. The Normal Curve Equivalents or NCE's and letter grades as given by the junior-high level science teachers at Crestwood, were analyzed using non-independent t tests. Descriptive data …
