Carrion Beetles (Coleoptera: Silphidae) Of Northeastern Iowa: A Comparison Of Baits For Sampling, David R. Coyle, Kirk J. Larsen

Journal of the Iowa Academy of Science: JIAS

Carrion beetles (Coleoptera: Silphidae) were inventoried over a 8-week period from June into August of 1996 at 10 sites in 4 counties of extreme northeastern Iowa. Carrion preference and relative abundance of carrion beetles were studied by use of non-lethal pitfall traps constructed from large plastic plant pots and baited with aged fish, beef liver, chicken, or piglets. A total of 3,183 carrion beetles were collected, representing 11 different species. The most commonly encountered species of carrion beetles in northeastern Iowa included Necrophila americana (71.5%) and Oiceoptoma novaboracense (18.5%). When comparing baits, chicken and fish attracted the greatest number of …

Decline Of Iowa Populations Of The Regal Fritillary (Speyeria Idalia) Drury, Diane M. Debinskl, Liesl Kelly

Journal of the Iowa Academy of Science: JIAS

The Regal Fritillary butterfly, Speyeria idalia Drury (Lepidoptera: Nymphalidae, Argynninae), is a prairie endemic species which has exhibited a dramatic decline in Iowa during the last few decades. Tallgrass prairie is the primary habitat of S. idalia and the butterfly's presence is correlated with the presence of violets (Violaceae). Due to the extensive habitat fragmentation of Iowa prairies, both the butterfly and its host plant populations are limited primarily to unplowed, relatively pristine prairies. Thus, S. idalia is an excellent case study of a prairie endemic species. Here, we report on the results of a two-year survey of the insect …

The Fungi, Lichens, And Myxomycetes Of Iowa: A Literature Review And Evaluation, Lois H. Tiffany, George Knaphus

Journal of the Iowa Academy of Science: JIAS

The fungi have been, and continue to be, a poorly documented portion of Iowa’s biological inheritance. Although many are perennially present in soil and plant debris and are crucially involved in the release and recycling of materials from organic residues or are partners with plant roots as mycorrhizae, they are not obvious until they produce fruiting structures such as mushrooms, boletes, brackets, puffballs, etc. The fungi causing plant disease are more obvious because of the reactions of their host plants; thus the earliest records of Iowa fungi are of ones causing plant diseases commonly referred to as mildews, rusts, and …

Iowa's Avifauna: Recent Changes And Prospects For The Future, James J. Dinsmore

Journal of the Iowa Academy of Science: JIAS

Iowa's avifauna has changed dramatically since 1980. The state list now has 40 additional species and totals 398 species, the most of any vertebrate group. Four species that had not previously nested in Iowa (Ring-billed Gull, Great-tailed Grackle, House Finch, Eurasian Tree Sparrow) and four whose nesting populations had disappeared (Double-crested Cormorant, Sandhill Crane, Piping Plover, Least Tern) now breed regularly here. Little Blue Heron, Cattle Egret, White-faced Ibis, Mississippi Kite, Prairie Warbler, and Red Crossbill nested for the first time but do not have established nesting populations. Trumpeter Swan, Peregrine Falcon, Greater Prairie Chicken, and Sharp-tailed Grouse have been …

Safety Issues And Iowa Science Teachers, Jack A. Gerlovich, Ed Wilson, Rahul Parsa

Journal of the Iowa Academy of Science: JIAS

The National Science Education Standards are providing an excellent blue print for improving science teaching for all students. However, the Standards are placing serious demands on teachers attempts to make science activities inquiry-based, real-life, open-ended, and directly applicable to today's students. This situation is further aggravated when teachers do not know essential science safety information from both federal and state governing agencies, as well as professional organizations. With proper training and tools, however, this problem can be positively addressed.

Iowa Prairie: Original Extent And Loss, Preservation And Recovery Attempts, Daryl D. Smith

Journal of the Iowa Academy of Science: JIAS

Iowa's prairie has to be assessed in the context of the pre- and post-agriculturally dominated ecosystem in which it now exists. This requires an understanding of prairies and of society's perspective of prairies. Therefore, the attitudes of people through time have to be considered; (1) those who were involved in the demise of the prairie, (2) those who helped saved the pieces of the prairie and (3) those who may be called upon to recover the prairie ecosystem.

Lack Of Genetic Variation In Cytochrome Bin A Population Of Smooth Softshell Turtles, David W. Weisrock, Tamara S. Haselkorn, Fredric J. Janzen

Journal of the Iowa Academy of Science: JIAS

An important issue in intraspecific molecular phylogenetic studies concerns distribution of genetic variation within and among populations and, hence, within-population sample sizes used in analyses. To address this sampling issue, we sequenced a 795 base pair (bp) segment of the mitochondrial cytochrome b gene from 19 unrelated individuals from a Louisiana population of the smooth softshell turtle (Apalone mutica LeSueur). We found a complete lack of within-population variation in this large segment of mtDNA. This result supports the use of minimal within-population sample sizes in intraspecific molecular phylogenetic studies of Apalone using cytochrome b.

Leafy Spurge (Euphorbia Esula L.) Spread In Iowa, S. C. Huerd, S. E. Taylor

Journal of the Iowa Academy of Science: JIAS

Leafy spurge (Euphorbia esula L.), a noxious perennial weed spreading south from the northern Great Plains into Iowa, is considered a threat to Iowa's Prairie preserves because it is an aggressive non-native plant that dominates the landscape through rapid sexual and asexual reproduction. Methods to control leafy spurge include cultural and chemical controls, and biological controls are currently being developed. In 1992 and 1993 we surveyed the extent of leafy spurge spread in Iowa and found 26 of 99 Iowa counties with leafy spurge populations. Iowa's leafy spurge populations are rapidly expanding on untilled lands such as roadsides, especially in …

Book Review - Birds In Iowa, Peter Wickham

Journal of the Iowa Academy of Science: JIAS

Here is a book that those who are interested in birds and their distribution in Iowa will absolutely have to possess. This volume is the successor to the book Iowa Birds, which was written by the above authors together with three others and published in 1984. It brings our understanding to the number of species of birds and their relative abundance in Iowa up-to-date. Although only twelve years elapsed between the publication of the previous volume and this one, the activity of those interested in identifying birds increased enormously during those years. In addition, their ability to identify and find …

Status Of Aquatic Vascular Plants 1n Iowa's Natural Lakes, G. S. Phillips

Journal of the Iowa Academy of Science: JIAS

Conversion of wetlands to agricultural land during the settlement of Iowa has resulted in a significant decline in the total area of lake habitat in the state. This reduction in area, combined with the degradation of remaining sites, resulted in dramatic reductions in aquatic vascular plant populations associated with Iowa's natural lakes. While declines in plant species inhabiting fen, bog, seepage, prairie pothole, and marsh type wetlands have been extensively documented, few quantitative data exist for lake type wetlands. During the summer of 1996, a total of 86 natural lakes in Iowa were surveyed for aquatic vascular plants. Many of …

Iowa's Odonata: Declining And/Or Changing?, Robert W. Cruden, O. J. Gode Jr.

Journal of the Iowa Academy of Science: JIAS

We undertook a comprehensive survey of the Order Odonata in Iowa. Because the credibility of our conclusions derives from our collecting strategy and effort, we discuss our strategy in depth. We collected throughout the state (more than 500 sites in 94 counties), throughout the flight season (late May-early October), and tried to visit several habitats in each county. Our 7900+ observations made between 1993 and 1996 include approximately 2300 county records, 93 of the 110 species reported for the state, and eight species previously unknown from the state. At least 30 species are secure and occur across the state. Other …

G98-1358 Feeding To Maximize Protein And Fat, Rick J. Grant

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes feeding guidelines to increase milk fat and protein production.

Proper feeding management of dairy herds can both improve the economy of production and provide a healthier cow. To achieve these goals, producers must feed to increase production of milk with maximum levels of milk fat and protein.

Milk solids components include fat, protein, lactose and minerals. Normal values for milk fat range from 3.7 percent (Holstein) to 4.9 percent (Jersey); milk protein ranges from 3.1 percent (Holstein) to 3.8 percent (Jersey). Lactose is usually 4.6–4.8 percent for all breeds; minerals (ash) average .74 percent. Because current milk …

Ec98-796 Farm*A*Syst Nebraska’S System For Assessing Water Contamination Worksheet 17: Stormwater Management At Residential Sites, Robert Grisso, Delynn Hay, Paul J. Jasa, Richard K. Koelsch, Sharon Skipton, Wayne Woldt

University of Nebraska-Lincoln Extension: Historical Materials

Stormwater is water from irrigation, rain or melting snow that does not soak into the ground. It flows from rooftops, over paved areas and bare soil, and across sloped lawns. As it flows, this runoff can collect and transport soil, pet waste, livestock manure, salt, pesticides, fertilizer, oil and grease, leaves, litter and other potential pollutants. A heavy rainstorm isn’t needed to send pollutants rushing toward streams, wetlands and lakes. A garden hose alone can supply enough water.

G98-1368 Medical Record Privacy, Mary Ellen Rider, Lisa Ahlberg, Judy Weber

University of Nebraska-Lincoln Extension: Historical Materials

Medical record privacy is an important issue of the 1990s. This NebGuide focuses on access to our medical records, the risks of inappropriate use of medical records, and what you as a health consumer can do should you face those risks.

Many of us think our medical records are confidential, seen only by our doctors. The truth is, however, a number of people have access to them. The real question is whether we have true privacy of our medical records.

Think of all the information in your medical records. In addition to diagnostic and testing information, they contain the details …

Ec98-749 Farm*A*Syst Nebraska’S System For Assessing Water Contamination Risk Fact Sheet 12: Improving Silage Storage, Robert Grisso, Delynn Hay, Paul J. Jasa, Richard K. Koelsch, Sharon Skipton, Wayne Woldt

University of Nebraska-Lincoln Extension: Historical Materials

Silage is an important feed for livestock-based agriculture. When properly harvested and stored, silage poses little or no pollution threat, but improper handling can lead to a significant flow of silage juices (or leachate) from the silo. Leachate is an organic liquid that results from pressure in the silo or from extra water entering the silo. It is usually a problem only when silage is fresh, or just after storage. This loss of leachate represents a loss of nutrient value from the silage.

Ec98-756 Farm*A*Syst Nebraska’S System For Assessing Water Contamination Risk Worksheet 13: Milking Center Effluent Treatment, Robert Grisso, Delynn Hay, Paul J. Jasa, Richard K. Koelsch, Sharon Skipton, Wayne Woldt

University of Nebraska-Lincoln Extension: Historical Materials

Why should I be concerned? Milking center effluent is usually considered a dairy sanitation problem. If not properly managed, however, the effluent can contaminate both groundwater and surface water.

Ec98-755 Farm*A*Syst Nebraska’S System For Assessing Water Contamination Risk Fact Sheet 13: Improving Milking Center Effluent Treatment, Robert Grisso, Delynn Hay, Paul J. Jasa, Richard K. Koelsch, Sharon Skipton, Wayne Woldt

University of Nebraska-Lincoln Extension: Historical Materials

Effluent from the dairy milking center, including discharges from the milking parlor (manure, feed solids, hoof dirt) and milkhouse (bulk tank and pipeline rinse water and detergent used in cleaning), is commonly disposed of in a variety of ways. Milking center effluent offers several unique challenges due to the presence of: 1. Large volumes of contaminated water which can overwhelm soil absorption systems. 2. Milk solids and fats and manure solids which plug many systems. 3. Cleaning sanitizers which reduce bacterial breakdown of solids. When these systems fail, effluent will become a risk to surface and groundwater quality.

Ec98-765 Farm*A*Syst Nebraska’S System For Assessing Water Contamination Fact Sheet 3: Improving Drinking Water Well Condition, Robert Grisso, Delynn Hay, Paul J. Jasa, Richard K. Koelsch, Sharon Skipton, Wayne Woldt

University of Nebraska-Lincoln Extension: Historical Materials

Groundwater protection is an important aspect of farm, ranch and rural homesite management today. Nearly all rural families rely on groundwater for their drinking water. Safeguarding the drinking water depends on where the well is placed on the site, how the well was constructed, how the well is maintained, the siting of new wells, and managing wells no longer in use.

Ec98-761 Farm*A*Syst Nebraska’S System For Assessing Water Contamination Worksheet 10: Livestock Yards Management, Robert Grisso, Delynn Hay, Paul J. Jasa, Richard K. Koelsch, Sharon Skipton, Wayne Woldt

University of Nebraska-Lincoln Extension: Historical Materials

Why should I be concerned? Livestock yards, such as barnyards, holding areas and feedlots, are areas of concentrated livestock wastes and a potential source of nutrient, solids, and bacteria contamination of surface and groundwater. Yards that are abandoned permanently or are inactive temporarily also represent a potential risk.

Ec98-770 Farm*A*Syst Nebraska’S System For Assessing Water Contamination Worksheet 5: Fertilizer Storage And Handling, Robert Grisso, Delynn Hay, Paul J. Jasa, Richard K. Koelsch, Sharon Skipton, Wayne Woldt

University of Nebraska-Lincoln Extension: Historical Materials

Why should I be concerned? Fertilizers play a vital role in agriculture. Over the years, fertilizers have increased farm production dramatically. Commercial fertilizer is, however, a major source of nitrate. Your drinking water is least likely to be contaminated if you follow appropriate management procedures or dispose of wastes off the farm site. However, proper offsite disposal practices are essential to avoid risking contamination that could affect the water supplies and health of others.

G98-1364 Feeding Children Ages 2 To 5, H. Darlene Martin

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide defines nutritional needs and healthy eating patterns for children ages 2 to 5.

Children Grow at Their Own Rate

Children move though growth spurts throughout childhood. Usually, a child will grow about 2 1/2 inches and gain about four or five pounds each year between the ages of 2 and 5. By 15 months old, most children have developed enough fine motor skills to feed themselves without help, if allowed to do so. Appetites vary with young children as well as adults. Parents and caregivers need to help promote a healthy pattern of eating rather than using controlling …
