Research Plan And Preliminary Results - A Field Research Site For Emerging Contaminants In Iowa, Douglas J. Schnoebelen, Dana W. Kolpin, Larry B. Barber, Edward T. Furlong, Michael M. Meyer, Mary Skopec

Journal of the Iowa Academy of Science: JIAS

Research has recently documented the prevalence of a wide variety of pharmaceuticals and other emerging contaminants (ECs) in streams across the United States. Wastewater treatment plants (WWTPs) have been found to be an important source and collection point of ECs to streams as many ECs are incompletely removed during treatment. To investigate the complex instream processes (e.g., dilution, sorption, degradation, dispersion, etc.) chat can affect ECs following their input from a WWTP and determining if such input is having an effect on the aquatic ecosystem requires the integration of multi-disciplinary efforts at a carefully selected field site. Preliminary work has …

Relation Of Riparian Buffer Strips To In-Stream Habitat, Macroinvertebrates And Fish In A Small Iowa Stream, Jeremy P. Duehr, Michael J. Siepker, Clay L. Pierce, Thomas M. Isenhart

Journal of the Iowa Academy of Science: JIAS

Macroinvertebrate and fish habitat is often degraded as a result of agriculture. Riparian buffer strips are commonly used to counteract the negative effects of agriculture in headwater streams. We assessed the relation of multi-aged riparian buffer strips to in-stream habitat, macroinvertebrate and fish assemblages in an Iowa stream. In-stream habitat, macroinvertebrates, and fish were sampled from two buffered sites and two unbuffered sites, with the greatest substrate, water depth, and velocity heterogeneity occurring in buffered sites. The highest macroinvertebrate richness (11) as well as fish species richness (14), diversity (1.99) and IBI score (37) were found in the site buffered …

Use Of Artificial Enclosures To Determine The Survival Of Rana Pipiens Larvae In Upper Midwestern Agricultural Ponds, Joshua M. Kapfer, Mark B. Sandheinrich, Melinda G. Knutson

Journal of the Iowa Academy of Science: JIAS

Amphibians in the upper Midwest use agricultural ponds for breeding. Unfortunately, the risks (both direct and indirect) associated with using these ponds are poorly understood in both amphibian adults and larvae. In order to quantify these risks, we performed a comparison of larval survival rates between agricultural and natural ponds in southeastern Minnesota during the spring and summer of 2001. During this time, larval survival was observed in Rana pipiens tadpoles raised through metamorphosis in enclosures placed in agricultural and natural ponds. In addition, we measured the levels of nutrients commonly linked with agricultural ponds (i.e., ammonia, total phosphorous, and …

The Effect Of Mandatory Continuing Education On Practice Quality And Competency Of Professional Land Surveyors, Anthony Richard Vannozzi

Electronic Theses and Dissertations

Mandatory Continuing Education (MCE) has always been a "hot button" topic in the professions and land surveying is no exception. Though most other professions (i.e. medicine, education, accountancy, dentistry, nursing, etc.) have included scientifically based research as part of their debate on whether to make continuing education mandatory, no empirical studies in land surveying were found. Though the land surveying literature is replete with anecdotal discussions on the topic, (commentaries, editorials, policy statements, magazine articles, etc.), and tremendous energy is being expended within the land surveying profession in debating and making decisions regarding the MCE issue, the lack of hard …

The Honey Creek Member: A New Holocene Alluvial Stratigraphic Unit In The Midwest, Jeremy S. Dillon, Rolfe D. Mandel

Journal of the Iowa Academy of Science: JIAS

This paper describes the type locality and type section for the Honey Creek Member, a stratigraphic unit first recognized in the Honey Creek drainage in southeastern Nebraska. The alluvial chronology for Honey Creek basin is similar to the regional chronology of streams in the Midwest, and all of the formal members of the DeForest Formation occur in the basin. However, the lithology of one unit, the Honey Creek Member, does not correlate with any of the formally recognized members of the DeForest Formation. The Honey Creek Member is composed of grayish brown silt loam overbank facies coarsening downward to a …
