For most people, pollen means allergies and bees mean stings. However, you should thank a bee, butterfly, bat, bird, or other pollinator for one out of every three bites of food you eat. Pollination is the transfer of pollen from one flower to another. It is a …

Thermotolerance And Rapid Cold Hardening Ameliorate The Negative Effects Of Brief Exposures To High Or Low Temperatures On Fecundity In The Flesh Fly, Sarcophaga Crassipalpis, Joseph Rinehart, George Yocum, David Denlinger

Entomology Papers from Other Sources

Although the immediate effects of temperature stress are well documented, the longer-term effects of such stresses are more poorly known. In these experiments, we investigate the effects of suboptimal and supraoptimal temperatures during pharate adult development on fecundity in the flesh fly, Sarcophaga crassipalpis Macquart. A 1 h cold shock at -10°C during the red-eye pharate adult stage decreases the fecundity of both sexes. Induction of rapid cold hardening by pre-treatment at 0°C for 2 h partially prevents reproductive impairment. Heat shock of pharate adults for 1 h at 45°C also reduces fecundity in both sexes, but inducing thermotolerance by …

Ec00-279 Synchronizing Esetrus In Beef Cattle, Richard J. Rasby, Gene H. Deutscher

University of Nebraska-Lincoln Extension: Historical Materials

Synchronization of estrus (heat) involves manipulating the estrous cycle of beef females in a herd so they can be bred at approximately the same time. There are several traditional protocols available for synchronizing estrus among beef females.

This extension circular discusses the programs and protocols used in synchronizing estrus in the beef cow.

Genes Classical And Genes Developmental: The Different Uses Of The Gene In Evolutionary Synthesis, Scott F. Gilbert

Biology Faculty Works

Dobzhansky (1964) stated that “Nothing in biology makes sense except in the light of evolution,” and the function of the gene is no exception. The use of genes in population genetics and developmental genetics differs significantly. This is reflected in the roles that genes are postulated to play in evolution. In the Modern Synthesis of population genetics and evolution, genes become manifest by differences in alleles that are active in conferring differential reproductive success in adult individuals. The gene is thought to act as a particulate, atomic unit. In current syntheses of evolution and developmental genetics, important genes are manifest …

Making Biomedical Policy Through Constitutional Adjudication:The Example Of Physician-Assisted Suicide, Carl E. Scheider

Book Chapters

Throughout most of American history no one would have supposed biomedical policy could or should be made through constitutional adjudication. No one would have thought that the Constitution spoke to biomedical issues, that those issues were questions of federal policy, or that judges were competent to handle them. Today, however, the resurgence of substantive due process has swollen the scope of the Fourteenth Amendment, the distinction between federal and state spheres is tattered, and few statutes escape judicial vetting. Furthermore, Abraham Lincoln's wish that the Constitution should "become the political religion of the nation" has been granted. "We now reverently …

Couples: Marriage, Civil Union, And Domestic Partnership, David L. Chambers

Book Chapters

In this country, during the last decades of the twentieth century, thousands of lesbians married other women and thousands of gay men married other men. Many of these couples recited traditional vows in churches and synagogues. Others have pledged to each other in their own backyards in words that they wrote themselves. But not one of these thousands of solemn occasions was recognized as creating a legally valid marriage. In the United States, each state has its own statute defining who can marry, and as far as the states were concerned, these couples were playing dress up. One state has …

Stamped With Glory: Lewis Tappan And The Africans Of The Amistad, Douglas O. Linder

Faculty Works

Abolitionism came relatively late to Lewis Tappan. Devotional, benevolent and hardworking are all words that describe Tappan in his twenties and thirties. Social reformer he was not. In 1818, Tappan abandoned the Calvinism of his mother for Unitarianism, then fashionable for a socially ambitious merchant. For the next eight years, Tappan enjoyed the typical life of an upper-middle-class New England merchant. He took his new faith seriously, however, editing a Unitarian journal, and becoming the first treasurer of the American Unitarian Association. In the mid-1820's, America experienced The Great Second Awakening, a widespread revival of religion and religious debate and …

Photo-Enhanced Toxicity In Amphibians: Synergistic Interactions Of Solar Ultraviolet Radiation And Aquatic Contaminants, Edward E. Little, Robin Calfee, Richard Skinker, Angela Zaga-Parkhurst, Mace G. Barron

Journal of the Iowa Academy of Science: JIAS

Amphibians experience a broad range of multiple environmental stressors that occur in natural systems. However, the impact of combinations of these stressors on amphibians are rarely examined. The effect of two stressors on amphibians, solar ultraviolet radiation (SUV) and environmental contamination, was investigated. To examine the interactive effects of SUV and environmental contaminants, Hyla venicolor and Rana sphenocephala were exposed in the laboratory to a carbamate insecticide and the water soluble fraction of a weathered petroleum in combination with various intensities of simulated solar radiation (SSR). The contaminants were tested at environmentally relevant concentrations. Synergistic interactions between SSR and these …

Effects Of Altosid And Abate-4e On Deformities And Survival In Southern Leopard Frogs Under Semi-Natural Conditions, Donald W. Sparling

Journal of the Iowa Academy of Science: JIAS

Since 1995 when a group of school children in Minnesota found frogs with supernumerary limbs and missing limbs, there has been widespread interest in the amphibian malformation issue. Despite considerable effort to understand this problem, its extent and seriousness as well as direct causes of these malformations remain unclear. Progress on this issue has been hampered by a scarcity of scientifically reliable information on historical rates of abnormalities under undisturbed conditions and by the normal turnaround times of data collection, sample analysis and publication. One of the very few peer-reviewed publications with field-collected data showed that an average of 12% …

Field Investigations Of Malformed Frogs In Minnesota 1993-97, Judy C. Helgen, Mark C. Gernes, Susan M. Kersten, Joel W. Chirhart, Jeff T. Canfield, Dorothy Bowers, Jon Haferman, Robert G. Mckinnell, David M. Hoppe

Journal of the Iowa Academy of Science: JIAS

Reports of malformed frogs were made to the Minnesota Pollution Control Agency (MPCA) from different parts of Minnesota in 1993, 1995, 1996, and 1997 and one, nine, 190, and 172 reports were received, respectively. MPCA field crews and Drs. Hoppe and McKinnell documented malformed frog locations starting in 1993. By 1997, MPCA field crews documented malformed frogs at 62 locations in Minnesota, in 29 of 87 counties. Most malformations were in young metamorphs of Rana pipiens but they were observed also in R. clamitans, R. septentrionalis, R. sylvatica, Bufo americanus, and Hyla spp. Frequencies of malformations varied by time of …

Revitalization Of Ephemeral Pools As Frog Breeding Habitat In An Illinois Forest Preserve, Denins Nyberg, Irene Lerner

Journal of the Iowa Academy of Science: JIAS

Almost all land in the eastern United States that has been acquired to preserve nature was once in agricultural usage, and because of this, alterations of ephemeral pool hydrology are common in forest preserves and parks. These ephemeral pools are an important breeding resource for many amphibian species. We hypothesized that filling drainage ditches and recreating a more natural topography at eroded berms would enhance amphibian populations in the forest preserve. Restoration of the hydrology was begun by volunteers in 1993 and was associated with management to reduce non-native woody vegetation. Three ephemeral pools have had maximum water levels raised …

Amphibian And Reptile Surveys In The Kaskaskia River Drainage Of Illinois During 1997 And 1998, Allan K. Wilson

Journal of the Iowa Academy of Science: JIAS

Currently there is little doubt among the scientific community of the decline of amphibians on an international scale (Berger et al. 1998, Kuzmin 1994, Laurance et al. 1996, Lips 1998) and across North America (Delis et al. 1996, Drost and Fellers 1996, Lannoo 1994). In light of these widespread declines it is essential that current populations be inventoried and evaluated so that future population changes can be detected and hopefully correlated with possible causes. Critical baseline information is lost when monitoring is not implemented until after a problem is detected. The effectiveness of long-term studies in detecting amphibian declines (Beebee …

[Review Of] Eric Greene. Planet Of The Apes As American Myth: Race, Politics, And Popular Culture, George H. Junne Jr

Ethnic Studies Review

Planet of the Apes (1968) was such a hit movie that it spawned several sequels. They included Beneath the Planet of the Apes (1970), Escape from the Planet of the Apes (1971), Conquest of the Planet of the Apes (1972), and Battle for the Planet of the Apes (1973). In the 1974 television season CBS broadcast the series "Planet of the Apes." NBC followed with the animated Saturday morning series (September, 1975-September, 1976), "Return to the Planet of the Apes." Eric Greene clearly demonstrates that the Apes saga is little more than the support of the American myth of triumphalism: …

Reading A.B. Guthrie's The Big Sky, Fred Erisman

Western Writers Series Digital Editions

Shortly after midday on 31 August 1837, thirty-four-year-old Ralph Waldo Emerson stepped before the Harvard chapter of the Phi Beta Kappa Society in Cambridge, Massachusetts, preparing to give the annual oration associated with the university’s commencement exercises. In the audience, in addition to some two hundred students, were such luminaries as the physician-essayist Oliver Wendell Holmes, the Abolitionist Wendell Phillips, the poet James Russell Lowell, and the governor of Massachusetts, Edward Everett, who later became president of Harvard. Emerson’s presentation, entitled “The American Scholar,” lasted for slightly more than an hour (Richardson 261-63).

From Helplessness To Hope: The Seminal Career Of Martin Seligman, S. F. Maier, C. Peterson, Barry Schwartz

Psychology Faculty Works

Provides a background to the history of research on learned helplessness and learned optimism, as well as M. Seligman's own involvement in these areas. The development of research in this area also illustrates two other important lessons in how science actually proceeds. First, it is often difficult to predict at the outset where research will lead. Work on learned helplessness began in the animal laboratory and for several years was directed at deep theoretical issues in the psychology of learning and not at depression, academic achievement, and other significant human phenomenon. And second, the history of learned helplessness research demonstrates …

The Constitutional Value Of Dialogue And The New Judicial Federalism, Lawrence Friedman

UC Law Constitutional Quarterly

Notwithstanding that the new judicial federalism is no longer new, the question remains whether there is a legitimate basis for state supreme courts to interpret provisions of state constitutions that parallel provisions of the United States Constitution differently than the United States Supreme Court has interpreted the latter. The Author suggests that the interpretation of cognate state constitutional provisions by state court is institutionally legitimate and normatively desirable within the framework of federalism. The legitimacy of the practice is supported by the constitutional value of dialogue - that is, the value that attaches to discourse about law and governance when …

Congress' Property Clause Power To Prohibit Taking Endangered Species, Sophie Akins

UC Law Constitutional Quarterly

In 1995, the Supreme Court in United States v. Lopez reined in Congress' commerce powers by holding that Congress may only regulate activities that substantially affect interstate commerce. Five years later, the Court in United States v. Morrison reaffirmed Lopez and held further that the Commerce Clause only supports Congress' regulation of activities that are economic in nature. This Note examines the repercussions of Lopez and Morrison on Congress' power to enact the Endangered Species Act under the Commerce Clause. Most scholars and courts seem to agree that the Endangered Species Act will fail under the Court's recent Commerce Clause …

The Cartagena Protocol And Biological Diversity; Biosafe Or Bio-Sorry, Jonathan H. Adler

Faculty Publications

In January 2000, delegates from over 100 nations completed negotiations on an international treaty for the regulation of biotechnology, the Cartagena Protocol on Biosafety. The stated purpose of this protocol is to enhance the protection of biological diversity. Despite its good intentions, there is a mismatch between the protocol's substantive provisions and present threats to biological diversity. The protocol endorses "precautionary" regulation of transboundary shipments of genetically engineered organisms, including crops, so as to reduce the environmental risks that such organisms may pose. The greatest threat to biological diversity is habitat loss, largely driven by the conversion of land for …
