Why Charlie Darwin Matters More Than Ever: Introducing Students To Evolution And The Nature Of Science, Brian Ellis, Anne H. Weaver Jan 2009

Why Charlie Darwin Matters More Than Ever: Introducing Students To Evolution And The Nature Of Science, Brian Ellis, Anne H. Weaver

Iowa Science Teachers Journal

In celebration of Charles Darwin's 200 Birthday and the 150 anniversary of the publication of his seminal work, On the Origin of Species, this is the first in a series of articles that highlight Darwin's relevance for teachers today and provide lesson plans to bring his work into your classroom. We begin with an introduction to Charles Darwin's life and work through storytelling, a first person monologue as a way to introduce students to several key concepts including the nature of science and a basic understanding of what lead Darwin to the concept of evolution.


Investigating Solutions Through Inquiry, Dana Frits, Chris Siguenza Jan 2009

Investigating Solutions Through Inquiry, Dana Frits, Chris Siguenza

Iowa Science Teachers Journal

In this article we discuss how many activities have valuable ideas, but important modifications must be made to make the activity more effective and mentally engaging. This article discusses the modification of a “cookbook” solubility lab into an inquiry activity, which increases student decisions and the promotion of higher-order thinking skills. We also address the critical role of the teacher in making the lesson effective. This article promotes National Science Education Standards A, B and G and Iowa Teaching Standards 2, 3, 4, and 6.


Learning Theories: Pillars Of Teacher Decision-Making, Jerrid Kruse Jan 2009

Learning Theories: Pillars Of Teacher Decision-Making, Jerrid Kruse

Iowa Science Teachers Journal

In the last issue, I articulated the argument that learning “styles” are not the most valuable way to understand learners. Yet, if learning “styles” do not sufficiently explain learning, how can we better conceptualize learning to inform our instruction?


Stepping Stones: How Variation Leads To Natural Selection, Anne H. Weaver, Brian Ellis Jan 2009

Stepping Stones: How Variation Leads To Natural Selection, Anne H. Weaver, Brian Ellis

Iowa Science Teachers Journal

This is the second of a series of articles in celebration of Charles Darwin's 200 birthday and the 150 anniversary of the publication of his seminal work On the Origin of Species. In the article below we discuss ways to introduce students to variation and develop their understanding of Natural Selection.


Divide & Conquer, Lauren Hackman, Audrey Pohlmann Jan 2009

Divide & Conquer, Lauren Hackman, Audrey Pohlmann

Iowa Science Teachers Journal

This article presents a modified biology lab used to teach the cell cycle. Many traditional versions of the onion root tip lab are delivered in a “cookbook” format to review what students have already learned about the phases of the cell cycle. This modified version illustrates how the onion root tip lab can be much more meaningful when turned into an inquiry-based, exploratory activity to scaffold from a concrete experience to the more abstract process of cell division. This article promotes National Science Education Standards A, C, and G and Iowa Core Curriculum Standards 1, 2, and 5.


Nuts About Inquiry: Peanut Variation And Natural Selection, Lindsay M. C. Kasuga, Christine Evans Jan 2009

Nuts About Inquiry: Peanut Variation And Natural Selection, Lindsay M. C. Kasuga, Christine Evans

Iowa Science Teachers Journal

Despite the numerous advantages of using inquiry, many teachers do not use this method because of issues such as time constraints and increased workload. In addition, content such as evolution is particularly problematic to teach because of the perceived lack of hands-on activities and societal pressures. This inquiry activity is designed to help students understand an important component of evolution by natural selection. Through this activity students better understand natural variation within populations using peanuts. Students are encouraged to make links between population data, population diversity and evolution by using collected data to construct and interpret graphs. This article promotes …


Managing Predators To Protect Endangered Species And Promote Their Successful Reproduction, Richard M. Engeman, Bernice Constantin, Kenneth S. Gruver, Corey Ross Jan 2009

Managing Predators To Protect Endangered Species And Promote Their Successful Reproduction, Richard M. Engeman, Bernice Constantin, Kenneth S. Gruver, Corey Ross

United States Department of Agriculture Wildlife Services: Staff Publications

Predation critically threatens many rare species, with the deleterious impacts of predation losses compounded by habitat loss. Predators of endangered species are frequently invasive species or artificially over-abundant native species. Often, predation is most damaging to a species' ability to reproduce. We use examples from the tropics to the tundra with which we have been involved to demonstrate how predator management can be a highly effective and economically efficient means to protect populations of rare species and enhance their reproduction.


Landscape-Genetic Analysis Of Population Structure In The Texas Gray Fox Oral Rabies Vaccination Zone, Randy Deyoung, Angeline Zamorano, Brian Mesenrink, Tyler A. Campbell, Bruce Leland, Guy Moore, Rodney Honeycutt, J. Jeffrey Root Jan 2009

Landscape-Genetic Analysis Of Population Structure In The Texas Gray Fox Oral Rabies Vaccination Zone, Randy Deyoung, Angeline Zamorano, Brian Mesenrink, Tyler A. Campbell, Bruce Leland, Guy Moore, Rodney Honeycutt, J. Jeffrey Root

United States Department of Agriculture Wildlife Services: Staff Publications

In west-central Texas, USA, abatement efforts for the gray fox (Urocyon cinereoargenteus) rabies epizootic illustrate the difficulties inherent in large-scale management of wildlife disease. The rabies epizootic has been managed through a cooperative oral rabies vaccination program (ORV) since 1996. Millions of edible baits containing a rabies vaccine have been distributed annually in a 16-km to 24-km zone around the perimeter of the epizootic, which encompasses a geographic area >4 x 105 km2. The ORV program successfully halted expansion of the epizootic into metropolitan areas but has not achieved the ultimate goal of eradication. Rabies …

United States Department of Agriculture Wildlife Services: Staff Publications

Chelydra serpentine serpentine (Common Snapping Turtle). Nesting Behavior and Site Selection. On May 31, 2008, we observed a ca. 36 cm CL Chelydra serpentine serpentine in unexpected nesting circumstances. Observations were made from 0908 to 1027 h on clear day with ambient temp ca 24° C. The nest site near Longmont, Colorado, USA (40.1599528°N, 105.1259861°W; WGS84) was 4.3 m from a seasonal ditch running north-south to connect two lakes, one on either side of a busy road. The intriguing aspect of the nest location was that it was immediately adjacent to a heavily traveled concrete sidewalk that bordered a road …


Escherichia Coli, Salmonella, And Mycobacterium Avium Subsp. Paratuberculosis In Wild European Starlings At A Kansas Cattle Feedlot, Shannon M. Gaukler, George M. Linz, Julie S. Sherwood, Neil W. Dyer, William J. Bleier, Yvonne M. Wannemuehler, Lisa K. Nolan, Catherine M. Logue Jan 2009

Escherichia Coli, Salmonella, And Mycobacterium Avium Subsp. Paratuberculosis In Wild European Starlings At A Kansas Cattle Feedlot, Shannon M. Gaukler, George M. Linz, Julie S. Sherwood, Neil W. Dyer, William J. Bleier, Yvonne M. Wannemuehler, Lisa K. Nolan, Catherine M. Logue

United States Department of Agriculture Wildlife Services: Staff Publications

The prevalence of Escherichia coli, Salmonella spp., and Mycobacterium avium subsp. paratuberculosis isolated from the feces of wild European starlings (Sturnus vulgaris) humanely trapped at a feedlot in central Kansas was assessed. All E. coli and Salmonella isolates recovered were tested for antimicrobial susceptibility using National Antimicrobial Resistance Monitoring System panels and the E. coli isolates were classified as to their content of genes associated with pathogenic E. coli of birds and cattle, including cvaC, iroN2, ompTp, hlyF2, eitC, iss, iutA, ireA, papC, stxI, stxII, sta, K99, F41, and eae. Escherichia coli O157:H7 and Mycobacterium avium …


Avian Use Of Harvested Crop Fields In North Dakota During Spring Migration, Alegra M. Galle, George M. Linz, H. Jeffrey Homan, William J. Bleier Jan 2009

Avian Use Of Harvested Crop Fields In North Dakota During Spring Migration, Alegra M. Galle, George M. Linz, H. Jeffrey Homan, William J. Bleier

United States Department of Agriculture Wildlife Services: Staff Publications

Broad-spectrum herbicide applications and improved harvesting efficiency of crops have reduced the availability of weed seeds and waste grains for game and nongame wildlife. Over the last decade, corn and soybean plantings have steadily increased in the Prairie Pothole Region (PPR) of North Dakota, while sunflower plantings have declined. The PPR is an important corridor for migratory birds, and changes in food availabilities at stopover habitats may affect how food resources are used. In early spring 2003 and 2004, we compared bird use of harvested fields of sunflower, soybeans, small grains, and corn in the PPR of North Dakota. Across …


Predator And Heterospecific Stimuli Alter Behavior In Cattle, Bryan M. Kluever, Larry D. Howery, Stewart W. Breck, David L. Bergman Jan 2009

Predator And Heterospecific Stimuli Alter Behavior In Cattle, Bryan M. Kluever, Larry D. Howery, Stewart W. Breck, David L. Bergman

United States Department of Agriculture Wildlife Services: Staff Publications

Wild and domestic ungulates modify their behavior in the presence of olfactory and visual cues of predators but investigations have not exposed a domestic species to a series of cues representing various predators and other ungulate herbivores.We used wolf (Canis lupus), mountain lion (Puma concolor), and mule deer (Odocoileus hemionus) stimuli (olfactory and visual), and a control (no stimuli) to experimentally test for differences in behavior of cattle (Bos taurus) raised in Arizona. We measured (1) vigilance, (2) foraging rates, (3) giving up density (GUD) of high quality foods and (4) time …


Physiological Stress Response Of Captive White-Tailed Deer To Video Collars, Remington Moll, Joshua J. Millspaugh, Jeff Beringer, Joel Sartwell, Rami Woods, Kurt C. Vercauteren Jan 2009

Physiological Stress Response Of Captive White-Tailed Deer To Video Collars, Remington Moll, Joshua J. Millspaugh, Jeff Beringer, Joel Sartwell, Rami Woods, Kurt C. Vercauteren

United States Department of Agriculture Wildlife Services: Staff Publications

Animal-borne video and environmental data collection systems (AVEDs) are an advanced form of biotelemetry that combines video with other sensors. As a proxy for physiological stress, we assessed fecal glucocorticoid metabolite (FGM) excretion in 7 white-tailed deer (Odocoileus virginianus) fitted with AVED dummy collars; 9 additional deer served as controls. We collected fecal samples over 3 2-week periods: pretreatment, treatment, and post-treatment periods. There were no differences in FGMs across time periods (F2,218 = 1.94, P = 0.147) and no difference between FGMs of control and treatment individuals (F1,14 = 0.72, P = 0.411). Fecal glucocorticoid …

United States Department of Agriculture Wildlife Services: Staff Publications

Our objective in this prospective study was to determine the natural course of Brucella abortus infection in cohorts of seropositive and seronegative, female bison (Bison bison) and their offspring in Yellowstone National Park (YNP) for 5 yr. We collected specimens from 53 adult females and 25 calves at least once and from 45 adults and 22 calves more than once. Annual seroconversion rates (negative to positive) were relatively high (23% for calves and juvenile bison, 6% in the total sample of adult female bison in our study, and 11% in the adult females that began the study as …


Wildlife Collisions With Aircraft: A Missing Component Of Land-Use Planning For Airports, Bradley F. Blackwell, Travis L. Devault, Esteban Fernández-Juricic, Richard A. Dolbeer Jan 2009

Wildlife Collisions With Aircraft: A Missing Component Of Land-Use Planning For Airports, Bradley F. Blackwell, Travis L. Devault, Esteban Fernández-Juricic, Richard A. Dolbeer

United States Department of Agriculture Wildlife Services: Staff Publications

Projecting risks posed to aviation safety by wildlife populations is often overlooked in airport land-use planning. However, the growing dependency on civil aviation for global commerce can require increases in capacity at airports which affect land use, wildlife populations, and perspectives on aviation safety. Our objectives were to (1) review legislation that affects airports and surrounding communities relative to managing and reducing wildlife hazards to aviation; (2) identify information gaps and future research needs relative to regulated land uses on and near airports, and the effects on wildlife populations; and (3) demonstrate how information regarding wildlife responses to land-use practices …


Assessing Allowable Take Of Migratory Birds, Michael Runge, John Sauer, Michael L. Avery, Bradley F. Blackwell, Mark Koneff Jan 2009

Assessing Allowable Take Of Migratory Birds, Michael Runge, John Sauer, Michael L. Avery, Bradley F. Blackwell, Mark Koneff

United States Department of Agriculture Wildlife Services: Staff Publications

Legal removal of migratory birds from the wild occurs for several reasons, including subsistence, sport harvest, damage control, and the pet trade. We argue that harvest theory provides the basis for assessing the impact of authorized take, advance a simplified rendering of harvest theory known as potential biological removal as a useful starting point for assessing take, and demonstrate this approach with a case study of depredation control of black vultures (Coragyps atratus) in Virginia, USA. Based on data from the North American Breeding Bird Survey and other sources, we estimated that the black vulture population in Virginia …


Ecological Correlates Of Risk And Incidence Of West Nile Virus In The United States, Brian F. Allan, R. Brian Langerhans, Wade A. Ryberg, William J. Landesman, Nicholas W. Griffin, Rachael S.

Ecological Correlates Of Risk And Incidence Of West Nile Virus In The United States, Brian F. Allan, R. Brian Langerhans, Wade A. Ryberg, William J. Landesman, Nicholas W. Griffin, Rachael S. Katz, Brad J. Oberle, Michele R. Schutzenhofer, Kristina N. Smyth, Annabelle De St. Maurice, Larry Clark, Kevin R. Crooks, Daniel E. Hernandez, Robert G. Mclean, Richard S. Ostfeld, Jonathan M. Chase

West Nile virus, which was recently introduced to North America, is a mosquito-borne pathogen that infects a wide range of vertebrate hosts, including humans. Several species of birds appear to be the primary reservoir hosts, whereas other bird species, as well as other vertebrate species, can be infected but are less competent reservoirs. One hypothesis regarding the transmission dynamics of West Nile virus suggests that high bird diversity reduces West Nile virus transmission because mosquito blood-meals are distributed across a wide range of bird species, many of which have low reservoir competence. One mechanism by which this hypothesis can operate …


Comparison Of Injuries To Coyote From 3 Types Of Cable Foot-Restraints, Patrick Darrow, Ramona Skirpstunas, S. Wade Carlson, John Shivik Jan 2009

Comparison Of Injuries To Coyote From 3 Types Of Cable Foot-Restraints, Patrick Darrow, Ramona Skirpstunas, S. Wade Carlson, John Shivik

United States Department of Agriculture Wildlife Services: Staff Publications

We compared injury rates among captured coyotes (Canis latrans) to determine if modifications to cable foot-restraints would decrease resulting injuries. Mean International Standardization Organization’s injury scores of coyotes caught in 3 types of cable foot-restraints were 22.2, 37.9, and 60.4 (F2,41 = 4.63, P = 0.015) for a chain-loop, standard cable, and sleeved cable, respectively. These results may be important for trappers and researchers to consider when using a cable foot-restraint device to capture wildlife.


Strawberry-Flavored Baits For Pharmaceutical Delivery To Feral Swine, Tyler A. Campbell, David B. Long Jan 2009

Strawberry-Flavored Baits For Pharmaceutical Delivery To Feral Swine, Tyler A. Campbell, David B. Long

United States Department of Agriculture Wildlife Services: Staff Publications

More effective methods to control feral swine (Sus scrofa) damage are needed. We evaluated 8 oral delivery systems designed to deliver pharmaceuticals to feral swine on 2 properties in southern Texas, USA. We used modified PIGOUT feral pig bait (Animal Control Technologies Australia P/L, Somerton, Victoria, Australia) throughout our trials to compare species-specific visitation and removal rates. Given our consistent finding of high non-target removal of baits intended for feral swine, we question whether a swine-specific oral delivery system exists for this region.


The Effects Of Aerosolized Brevetoxin Exposure On The Human Respiratory System, Katie M. Spaulding Jan 2009

The Effects Of Aerosolized Brevetoxin Exposure On The Human Respiratory System, Katie M. Spaulding

International Journal of Global Health and Health Disparities

While much information has been collected about the effects of brevetoxin ingestion in contaminated seafood, there has been very little research conducted and little is known about the effects of these toxins when inhaled in aerosols (Backer et al., 2003). The effects of brevetoxins are of great public health concern because not only are harmful algal blooms increasing in frequency and duration of occurrence, they are also expanding their area of distribution (Sellner et al., 2003; Kirkpatrick, 2004). Since a significant proportion of the world's population live within 75 miles of an ocean coast and this density of human coastal …

"False But Highly Persuasive": How Wrong Were The Probability Estimates In Mcdaniel V. Brown?, David H. Kaye Jan 2009

"False But Highly Persuasive": How Wrong Were The Probability Estimates In Mcdaniel V. Brown?, David H. Kaye

Michigan Law Review First Impressions

In McDaniel v. Brown, the Supreme Court will review the use of DNA evidence in a 1994 trial for sexual assault and attempted murder. The Court granted certiorari to consider two procedural issues—the standard of federal postconviction review of a state jury verdict for sufficiency of the evidence, and the district court's decision to allow the prisoner to supplement the record of trials, appeals, and state postconviction proceedings with a geneticist's letter twelve years after the trial. The letter from Laurence Mueller, a professor at the University of California at Irvine, identified two obvious mistakes in the state's expert testimony. …


The Gay Agenda, Libby Adler Jan 2009

The Gay Agenda, Libby Adler

Michigan Journal of Gender & Law

This Article is designed to illuminate options that the author believes have been difficult for advocates of gay rights to imagine due to an incessant culture war and the hard work of anti-gay forces that have kept pro-gay advocates under persistent fire. The culture war, this paper argues, while a fundraising boon and a media draw, compels a particular type of participation and a particular reform agenda, eclipsing reform possibilities that might be preferable in the long run.


Does Misery Love Company - Evidence From Pharmaceutical Markets Before And After The Orphan Drug Act, Frank R. Lichtenberg, Joel Waldfogel Jan 2009

Does Misery Love Company - Evidence From Pharmaceutical Markets Before And After The Orphan Drug Act, Frank R. Lichtenberg, Joel Waldfogel

Michigan Telecommunications & Technology Law Review

The possibility that small populations would see few medications developed for their conditions has [...] led the U.S. Congress to pass the 1983 Orphan Drug Act ("ODA"), giving firms special incentives to develop drugs for diseases afflicting fewer than 200,000 persons per year.[...][U]under the Act, drug makers receive seven years of exclusive marketing upon FDA approval of newly-developed drugs qualifying as "orphan drugs"--i.e., drugs for disorders affecting fewer than 200,000 persons.[...]Together, [the] provisions (a) increase the effective market size; and (b) reduce fixed (sunk) costs. In doing so, the Act provides a natural experiment for measuring the impact of increased …


Platitudes About Product Stewardship In Torts: Continuing Drug Research And Education, Lars Noah Jan 2009

Platitudes About Product Stewardship In Torts: Continuing Drug Research And Education, Lars Noah

Michigan Telecommunications & Technology Law Review

This Article focuses on one emerging aspect of tort litigation against pharmaceutical manufacturers that, if it gained traction, portends a dramatic (and potentially counterproductive) expansion in the prescription drug industry's exposure to liability. The traditional theories of products liability--mismanufacture, defective design, and inadequate warnings--no longer exhaust the potential obligations of sellers. In addition to increasingly popular claims of misrepresentation and negligent marketing, which seem more like extensions of the three defect categories than entirely novel theories, a growing chorus of commentators would impose on pharmaceutical manufacturers a broader duty to test and educate (aspects of what they call an obligation …


Pdufa And Initial U.S. Drug Launches, Mary K. Olson Jan 2009

Pdufa And Initial U.S. Drug Launches, Mary K. Olson

Michigan Telecommunications & Technology Law Review

In the 1970s and 1980s, many pharmaceutical firms launched new drugs abroad prior to gaining U.S. approval. Consequently, U.S. patients often faced delays in accessing important new medicines. High regulatory barriers to entry, such as a stringent regulation and a lengthy drug review process, contributed to this problem. This Article examines the impact of the Prescription Drug User Fee Act (PDUFA), and subsequent increases in the speed of FDA review, on the likelihood of initial U.S. drug launches. These factors are hypothesized to lower regulatory barriers to entry in the U.S. pharmaceutical market. The results show that increased drug review …


Why Fdca Section 505(U) Should Not Concern Us Greatly, Kyle Faget Jan 2009

Why Fdca Section 505(U) Should Not Concern Us Greatly, Kyle Faget

Michigan Telecommunications & Technology Law Review

Among the many amendments found in the Food and Drug Administration Amendment Act of 2007 (FDAAA) is a provision at the end of the act, Section 505(u), which grants chiral switches five years of market exclusivity under certain circumstances. Prior to Congressional enactment of the FDAAA, the Food and Drug Administration (FDA) refused to award new chemical entity (NCE) status to enantiomers of previously approved racemic mixtures. The FDA defines a new chemical entity ("NCE") as a drug that contains no active moiety that has been approved by the FDA in any other application submitted under Section 505(b) of the …


When And How To Defer To The Fda: Learning From Michigan's Regulatory Compliance Defense, Jason C. Miller Jan 2009

When And How To Defer To The Fda: Learning From Michigan's Regulatory Compliance Defense, Jason C. Miller

Michigan Telecommunications & Technology Law Review

Michigan's regulatory compliance defense properly recognizes that an FDA-approved drug carrying an FDA-approved label should not be considered defective. However, the statute's absolute immunity provides no compensation for injured parties in any circumstance, including situations where the FDA process has failed. Nevertheless, it is possible to treat the FDA's approval as significant without eliminating the possibility of all state actions against drug makers by providing a litigation back-up through state attorneys general ("AGs"). This Note examines the question of FDA approval in state tort actions in Part I, discusses Michigan's answer to that question in Part II, and offers a …
