Helminth Ova Recovered From Raptors Admitted For Rehabilitation, Shawn Hawks, Rick Klann
Helminth Ova Recovered From Raptors Admitted For Rehabilitation, Shawn Hawks, Rick Klann
Journal of the Iowa Academy of Science: JIAS
Fecal samples from 34 raptors admitted for rehabilitation were examined for helminth ova. All 34 birds, representing 13 different species, passed helminth ova in their feces. Six different types of helminth ova were identified, including strigeid trematode, cestode, Capillaria, Porrocaecum, Ascaridia and spiurid nematode. From this study, it appears that helminths, particularly tapeworms, are common parasites of raptors.

Research Note: Records Of Thirteen Ground Beetles (Coleoptera: Carabidae) New To Iowa, Foster Forbes Purrington, Kirk Jon Larsen
Journal of the Iowa Academy of Science: JIAS
A long-term ecological research initiative in northeast Iowa tallgrass prairies to evaluate the effects of prescribed burning on prairie insects was begun in 1993. During the course of this work we discovered 13 ground beetle species (Coleoptera: Carabidae) (Table 1) not previously reported from Iowa (Bousquet and Larochelle 1993).

The Contributions Of J. A. Udden To An Understanding Of Iowa Geology, Richard C. Anderson
The Contributions Of J. A. Udden To An Understanding Of Iowa Geology, Richard C. Anderson
Journal of the Iowa Academy of Science: JIAS
Johan August Udden served on the faculty of Augustana College from 1888 until 1911. His research during that time was directed toward an understanding of the geology of areas close at hand, the region around Rock Island and nearby areas in Iowa and Illinois. Udden's most significant contributions to Iowa geology were in his treatment of 1) Paleozoic, Cretaceous, and Quaternary stratigraphy; 2) subsurface geology, including information on bedrock elevations and topography; 3) characteristics and origin of the loess. Most of this information was included in the Annual Reports of the Iowa Geological Survey published between 1899 and 1903. He …

Fungal Colonization Of Alfalfa Stubble Following Harvest, J. K. O'Mara, G. P. Munkvold
Fungal Colonization Of Alfalfa Stubble Following Harvest, J. K. O'Mara, G. P. Munkvold
Journal of the Iowa Academy of Science: JIAS
Two-year-old stands of alfalfa cultivars Saranac and Vernal, planted in Central Iowa, were sampled 0, 15, and 30 days after the first harvest in 1995 to identify fungi colonizing the stubble left after harvest and evaluate the role of harvest-induced wounds as infection sites for potential crown-rotting fungi. Analysis of variance was conducted to determine if sampling date and cultivar significantly affected incidence of the fungi. All stems were infected with at least one fungal species at every sampling dare. The fungal genera most frequently isolated were Alternaria, Colletotrichum, Fusarium, Phoma, and Rhizoctonia. Fusarium acuminatum was the most frequently isolated …
Carnivorous Spadefoot (Spea Bombifrons Cope) Tadpoles And Fairy Shrimp In Western Iowa, Eugenia S. Farrar, Jane D. Hey
Carnivorous Spadefoot (Spea Bombifrons Cope) Tadpoles And Fairy Shrimp In Western Iowa, Eugenia S. Farrar, Jane D. Hey
Journal of the Iowa Academy of Science: JIAS
Amphibian larval polymorphisms, rarely found in the Midwest, are more common in arid western regions. We have discovered that Plains spadefoot toad, Spea bombifrons Cope, tadpoles occur as carnivorous and omnivorous morphological forms in flooded soybean and corn fields on the Missouri River flood plain of western Iowa. Carnivores have longer snouts, larger beaks with an upper cusp and lower notch, shorter intestines with fewer loops than the omnivores, and they feed on fairy shrimp. A similar polymorphism in Spea multiplicata Cope enhances survival in the desert because the carnivore develops faster after consuming fairy shrimp and is able to …
A Search For Average, Extremes, And Runs Of Unusual Weather In Iowa, R. E. Carlson, D. P. Todey
A Search For Average, Extremes, And Runs Of Unusual Weather In Iowa, R. E. Carlson, D. P. Todey
Journal of the Iowa Academy of Science: JIAS
Temperature and precipitation during the past decade have exhibited wide variation throughout Iowa. Is this unusual? An attempt was made to answer this question by computing various statistical parameters that characterize variation in Iowa's long term climatic record. Absolute deviations were used to identify the most and least variable months and years since 1900. Overall, 1936 with a very cold winter and very warm summer was the least normal year. Runs of daily weather showed that heat and cold stress could often persist for more than 1 month. Runs of dry days were much longer than runs of wet days. …

Test 1727: John Deere 7710 Powershift Diesel 19-Speed, Nebraska Tractor Test Lab
Nebraska Tractor Tests
EXPLANATION OF THE TEST PROCEDURE General Tractors are tested at the University of Nebraska according to the Agricultural Tractor Test Code approved by the American Society of Agricultural Engineers and the Society of Automotive Engineers or official Nebraska test procedure. The manufacturer selects the tractor to be tested and certifies that it is a stock model. Each tractor is equipped with the common power consuming accessories such as power steering, power lift pump, generator, etc., if available. Power consuming accessories may be disconnected only when the means for disconnecting can be reached from the operating station. An official representative of …
