Effects Of Field Size And Landscape Composition On Grassland Birds In South-Central Iowa, David Joseph Horn, Rolf R. Koford, Malinda L. Braland Jan 2002

Effects Of Field Size And Landscape Composition On Grassland Birds In South-Central Iowa, David Joseph Horn, Rolf R. Koford, Malinda L. Braland

Journal of the Iowa Academy of Science: JIAS

Many species of grassland birds have been shown to avoid smaller fields. The avoidance of smaller fields, however, has not been consistently reported; avoidance may occur in one study, but not in another. To examine one possible reason for these inconsistencies, we examined how landscape composition influenced the relations between occurrence or abundance and field size. The study took place during the 1998 breeding season on 44 Conservation Reserve Program (CRP) fields located in Adair, Ringgold, and Union counties. The relations between occurrence, abundance, and field size were not influenced by landscape composition for any species.

Inheritance Of Gray Leaf Spot Resistance In Corn, J. M. D. Crowley, A. R. Hallauer, C. A. Martinson

Journal of the Iowa Academy of Science: JIAS

Gray leaf spot disease, caused by Cercospora zeae-maydis Tehon and Daniels, has become a significant disease in Iowa corn (Zea mays L.) production. Incidence of gray leaf spot has increased with the increased use of conservation tillage practices. The inheritance of resistance to gray leaf spot was studied via use of generation mean analyses for five crosses and via use of 100 S1 progenies developed from an F2 population. Experiments were conducted at two locations that included either natural or artificial inoculation with C. zeae-maydis spores. Additive and dominance effects were significant in nearly all instances. Heritability for …


Fungi And Diseases Associated With Cultivated Switchgrass In Iowa, C. E. Gravert, G. P. Munkvold Jan 2002

Fungi And Diseases Associated With Cultivated Switchgrass In Iowa, C. E. Gravert, G. P. Munkvold

Journal of the Iowa Academy of Science: JIAS

Switchgrass (Panicum virgatum L.) is a native perennial prairie grass that is now cultivated as a forage crop and a biomass crop for renewable energy. Biomass yields of switchgrass in southern Iowa have recently dropped significantly in some fields and the reduction has been attributed to disease. A disease survey was conducted in 1999 to assess the prevalence of major diseases in Chariton Valley switchgrass production. There were disease symptoms present on switchgrass plants in each field and thirteen fungal species were identified from leaf, stem, and root samples. Two pathogenic fungi, Tilletia maclaganii and Colletotrichum graminicola, were present in …


Book Review - Prairie Birds: Fragile Splendor In The Great Plains, Neil P. Bernstein Jan 2002

Book Review - Prairie Birds: Fragile Splendor In The Great Plains, Neil P. Bernstein

Journal of the Iowa Academy of Science: JIAS

Paul A. Johnsguard has established himself as one of the most prolific natural history writers in the recent past. Indeed, before I could finish reading Prairie Birds, the University of Kansas Press sent me The Nature of Nebraska, also by Johnsguard. These works follow closely after This Fragile Land, A Natural History of the Nebraska Sandhills (1995), which I favorably reviewed a few years ago, also about the Great Plains. It goes without saying, that there is a fair amount of overlap in these works, both in the subject matter and the illustrations. Rather than criticize the overlap among these …
