Does Increasing Biology Teacher Knowledge Of Evolution And The Nature Of Science Lead To Greater Advocacy For The Teaching Of Evolution In Schools?, Ross Nehm, Irvin Sam Schonfeld Jan 2007

Does Increasing Biology Teacher Knowledge Of Evolution And The Nature Of Science Lead To Greater Advocacy For The Teaching Of Evolution In Schools?, Ross Nehm, Irvin Sam Schonfeld

Publications and Research

This study investigated whether or not an increase in secondary science teacher knowledge about evolution and the nature of science gained from completing a graduate-level evolution course was associated with greater preference for the teaching of evolution in schools. Forty-four precertified secondary biology teachers participated in a 14-week intervention designed to address documented misconceptions identified by a precourse instrument. The course produced statistically significant gains in teacher knowledge of evolution and the nature of science and a significant decrease in misconceptions about evolution and natural selection. Nevertheless, teachers' postcourse preference positions remained unchanged; the majority of science teachers still preferred …

Weather Factors Influencing Winter Roosts Of American Crows In Central Iowa, Joshua D. Obrecht, Stephen J. Dinsmore Jan 2007

Weather Factors Influencing Winter Roosts Of American Crows In Central Iowa, Joshua D. Obrecht, Stephen J. Dinsmore

Journal of the Iowa Academy of Science: JIAS

We investigated the effects of season and weather on the winter roosting behavior of American Crows (Corvus brachyrhynchos) in central Iowa from January through March 2006. The peak number of birds recorded at a roost in Ames, Story County was 9,000+ in early February, and the number of individuals entering the roost decreased through February and March. Crows tended to enter the roost later in the day as winter neared completion. High wind speed and low light intensity caused individual to enter the roost earlier in the day. Temperature did not affect arrival time of crows. Wind speed, light intensity, …

An Inventory Of The Vascular Flora Of Hamilton County, Iowa (2001-2004), Jimmie D. Thompson Jan 2007

An Inventory Of The Vascular Flora Of Hamilton County, Iowa (2001-2004), Jimmie D. Thompson

Journal of the Iowa Academy of Science: JIAS

A botanical survey of the vascular flora of Hamilton County, Iowa was conducted from 2001 to 2004. During this survey 973 taxa (761 native) were encountered. A search of the literature and a survey of Iowa State University's Ada Hayden Herbarium for additional documented specimens added 28 taxa to the flora. This total of 1001 taxa places Hamilton County fourth in vascular plant richness among inventories conducted in Iowa since 1950. A checklist including common names of most taxa, habitat and abundance data for all taxa encountered during the current survey is presented. Information on earlier collections includes source and …

Narrow Sense Heritability And Additive Genetic Correlations In Alfalfa Subsp. Falcata, Heathcliffe Riday, E. Charles Brummer Jan 2007

Narrow Sense Heritability And Additive Genetic Correlations In Alfalfa Subsp. Falcata, Heathcliffe Riday, E. Charles Brummer

Journal of the Iowa Academy of Science: JIAS

The complex genetics of autotetraploid alfalfa (Medicago sativa L.) make additive genetic variance component estimation difficult. Halfsib family variances often are used to estimate additive genetic variances and, by extension, narrow sense heritabilities and additive genetic correlations. These estimates contain a portion of the dominance variance. Using such calculations, in conjunction with parent-offspring covariance estimates, the dominance component can be separated from the additive genetic component. This is rarely done. This study reports average estimates across 30 populations, of both additive and dominance variance component estimates based on between halfsib family variance and parent-offspring covariance for biomass yield, plant height, …


Fall And Winter Food Habits Of Bobcats (Lynx Rufus) In Iowa, Kelcey J. Brockmeyer, William R. Clark Jan 2007

Fall And Winter Food Habits Of Bobcats (Lynx Rufus) In Iowa, Kelcey J. Brockmeyer, William R. Clark

Journal of the Iowa Academy of Science: JIAS

The bobcat (Lynx rufus) is a widely distributed native felid of North America but nearly disappeared from Iowa due to habitat loss and unregulated harvest that occurred during the century after European settlement. Bobcats are repopulating the state and are now relatively common in southern Iowa. This study was part of a research project to understand the ecology of the species in Iowa's landscape so that conservation plans could be established. We determined food habits by the examination of stomach contents from 100 bobcat carcasses that were accidentally killed in traps, killed by automobiles, or radio-marked individuals found dead during …

Laboratory Abrasion Of Crinoid Columnals And The Provenance Of The Chariton Conglomerate, South-Central Iowa, Justin C. Kraber, Steven H. Emerman, Matt R. Bennett, Lyndon R. Hawkins, Jewell E. Moore, Rebekah Ellenwood, Kristine L. Robson, Adam Finken

Journal of the Iowa Academy of Science: JIAS

The Chariton Conglomerate is a quartz limestone conglomerate of Pennsylvanian age found in six exposures in southern Iowa and three exposures in northern Missouri. Distinctive features of the exposures in Iowa include quartz granules and rounded crinoid columnals. The objective of this study was to determine whether the quartz clasts could have originated in the crystalline rocks of Minnesota or Wisconsin. The average paleocurrent direction measured in interbedded sandstones was 178° (S.D. = 35 °). The average roundness of 75 crinoid columnals extracted from four exposures in Iowa was 30% (S.D. = 14%), defined as

roundness(%) = (D-d)/D x 100, …

The Pet Food Recall Puzzle: Who, What, Why, And How Much, Roxanne Greitz Miller Jan 2007

The Pet Food Recall Puzzle: Who, What, Why, And How Much, Roxanne Greitz Miller

Education Faculty Articles and Research

Last spring, North America was gripped in the largest pet food recall in history. News outlets reported tens of thousands of dogs and cats becoming ill, and many dying, as a result of ingesting contaminated pet food. Several pet owners have filed lawsuits against the manufacturers and distributors of the pet food products. I think this is an excellent real-life science story to use with students to show science investigation in action, and to discuss the intersections between the role of regulatory agencies and the public.

In order to understand the case, you first have to know the facts. We'll …
