Optimal Foraging In Eastern Fox Squirrel: Food Size Matters For A Generalist Forager, Robert Tatina

The Prairie Naturalist

Classical optimal foraging theory (OFT) predicts that an animal forages optimally when it chooses foods with the highest energy benefit or minimizes time searching for and handling food. r evaluated OFT by presenting eastern fox squirrel (Sciurus niger) multiple food items (i.e., sunflower seeds and • fruits) in various density combinations. When the choice was between foods of equal energy benefits but different costs, they chose forage items with greater costs, seemingly not foraging optimally. However, individuals showed a partial preference for food items which minimized search time, but not handling time. The eastern fox squirrel also was …

Review Of Appreciating Your Feathered Neighbors, By Dana Gardner And Nancy Overcott, Melinda G. Knutson

The Prairie Naturalist

Fifty Common Birds of the Upper Midwest. Watercolors by Dana Gardner; text by Nancy Overcott. 2006. University of Iowa Press, Iowa City, Iowa. 106 pages. $34.95 (cloth).

What's the best way to interest a friend in bird watching? Buy them a field guide, a CD of bird songs, or take them out bird watching? All of these ideas might work, but another approach is to tell personal stories and draw pictures of common birds in yards, parks, and natural areas where they live; help them "get to know their neighbors with feathers." That's exactly what Dana Gardner and Nancy Overcott …

In Memoriam Robert N. Randall, October 26, 1915 - January 30, 2007, Clark Talkington

The Prairie Naturalist

Among his friends, Bob Randall will be remembered as a caring, gentle man. Bob was one of those rare individuals who had a keen awareness of everyone around him. In social settings, he would make sure that everyone was comfortable, and it was always clear that he was genuinely concerned about everyone. Those who knew him will greatly miss his gentle nature and enthusiasm for birds. He never got caught up in all of his achievements. He had a sense of balance to his life which was evident in his many interests including birding and bird banding, rocks and minerals, …

Ocean Currents And Sea Surface Heights Estimated Across The West Florida Shelf, Yonggang Liu, Robert H. Weisberg

Marine Science Faculty Publications

The across-shelf structures of the ocean circulation and the associated sea surface height (SSH) variability are examined on the west Florida shelf (WFS) for the 3-yr interval from September 1998 to December 2001. Five sets of characteristic circulation patterns are extracted from 2-day, low-pass-filtered data using the self-organizing map: extreme upwelling and downwelling structures with strong currents, asymmetric upwelling and downwelling structures with moderate currents, and a set of transitional structures with weak currents. The temporal variations of these structures are coherent with the local winds on synoptic weather time scales. On seasonal time scales they are related to both …

The Role Of International Ngos In The Intellectual Property Policy-Making And Norm-Setting Activities Of Multilateral Institutions, Duncan Matthews

Chicago-Kent Law Review

International NGOs play a significant role in relation to intellectual property policy-making and norm-setting in the following multilateral institutions: the World Trade Organization ("WTO"); the World Intellectual Property Organization ("WIPO"); the World Health Organization ("WHO"); the Convention on Biological Diversity Conference of the Party ("CBD-COP"); and the Food and Agriculture Organization ("FAO') of the United Nations. International NGOs enhance the capacity of developing country delegates to multilateral institutions to negotiate on intellectual property issues. Although there are limits to the relationship between developing country delegates and international NGOs, relative to the resources available, international NGOs have had a considerable impact, …

Technological Change And The Design Of Plant Variety Protection Regimes, Mark D. Janis, Stephen Smith

Chicago-Kent Law Review

In this paper, we examine the potential for plant variety protection ("PVP") regimes—that is, sui generis, industry-specific intellectual property regimes—to become compromised as a result of technological change. In particular, we analyze the shift in plant breeding from phenotypic selection to genotypic selection, and consider the impact of that shift on existing plant variety protection. We also lay out an alternative structure for plant intellectual property protection based on unfair competition, a model that differs radically in some respects from current PVP schemes. We offer our model as a starting point for debate on adaptations that might improve PVP …

The Technology Of Immortality, The Soul, And Human Identity, Richard A. Jones

Wagadu: A Journal of Transnational Women's & Gender Studies

In this paper, I argue that human beings will soon achieve immortality, but that that immortality will be neither the theistic promise of resurrection of the body nor the soul. Rather, I suggest that technological immortality—the ability through pure techné to reproduce any human life ever lived—is not only possible, but inevitable. Moreover, more than a cursory survey of the biological sciences, computer technology, and fictive literature, this essay also examines the normative dimensions of this near-future reality; ought we or ought we not?

Freakonomics And The Tax Gap: An Applied Perspective , Leslie Book

American University Law Review

Over the past thirty years, a significant amount of research from a variety of social science disciplines has considered tax compliance. Economists, psychologists, and sociologists have contributed to the discussion, offering research and, at times, conflicting explanations regarding whether a person is likely to comply with his obligation to file an accurate tax return. The unifying theme among this research is a search for explanatory reasons which are the factors that lead to non-compliance. In broad terms, the economic models of tax compliance assume rational behavior, and that people will coldly consider compliance from the perspective as to whether the …

The Stat5a-Mediated Induction Of Pyruvate Dehydrogenase Kinase 4 Expression By Prolactin Or Growth Hormone In Adipocytes, Ursula A. White, Ann A. Coulter, Tiffany K. Miles, Jacqueline M. Stephens

Faculty Publications

The purpose of this study was to determine whether pyruvate dehydrogenase kinase (PDK)4 was expressed in adipocytes and whether PDK4 expression was hormonally regulated in fat cells. Both Northern blot and Western blot analyses were conducted on samples isolated from 3T3-L1 adipocytes after various treatments with prolactin (PRL), growth hormone (GH), and/or insulin. Transfection of PDK4 promoter reporter constructs was performed. In addition, glucose uptake measurements were conducted. Our studies demonstrate that PRL and porcine GH can induce the expression of PDK4 in 3T3-L1 adipocytes. Our studies also show that insulin pretreatment can attenuate the ability of these hormones to …

Characterization Of Beaf Mutations Isolated By Homologous Recombination In Drosophila, Swarnava Roy, Matthew K. Gilbert, Craig M. Hart

Faculty Publications

The Drosophila BEAF-32A and BEAF-32B proteins bind to the scs′ insulator and to hundreds of other sites on Drosophila chromosomes. These two proteins are encoded by the same gene. We used ends-in homologous recombination to generate the null BEAFAB-KO allele and also isolated the BEAF A-KO allele that eliminates production of only the BEAF-32A protein. We find that the BEAF proteins together are essential, but BEAF-32B alone is sufficient to obtain viable flies. Our results show that BEAF is important for both oogenesis and development. Maternal or zygotic BEAF is sufficient to obtain adults, although having only maternal BEAF impairs …

Molecular Phylogeny Of The Scincid Lizards Of New Caledonia And Adjacent Areas: Evidence For A Single Origin Of The Endemic Skinks Of Tasmantis, Sarah A. Smith, Ross A. Sadlier, Aaron M. Bauer, Christopher C. Austin, Todd Jackman

Faculty Publications

We use ∼1900 bp of mitochondrial (ND2) and nuclear (c-mos and Rag-1) DNA sequence data to recover phylogenetic relationships among 58 species and 26 genera of Eugongylus group scincid lizards from New Caledonia, Lord Howe Island, New Zealand, Australia and New Guinea. Taxon sampling for New Caledonian forms was nearly complete. We find that the endemic skink genera occurring on New Caledonia, New Zealand and Lord Howe Island, which make up the Gondwanan continental block Tasmantis, form a monophyletic group. Within this group New Zealand and New Zealand + Lord Howe Island form monophyletic clades. These clades are nested within …

Endonuclease-Independent Insertion Provides An Alternative Pathway For L1 Retrotransposition In The Human Genome, Shurjo K. Sen, Charles T. Huang, Kyudong Han, Mark A. Batzer

Faculty Publications

LINE-1 elements (L1s) are a family of highly successful retrotransposons comprising ∼ 17% of the human genome, the majority of which have inserted through an endonuclease-dependent mechanism termed target-primed reverse transcription. Recent in vitro analyses suggest that in the absence of non-homologous end joining proteins, L1 elements may utilize an alternative, endonuclease-independent pathway for insertion. However, it remains unknown whether this pathway operates in vivo or in cell lines where all DNA repair mechanisms are functional. Here, we have analyzed the human genome to demonstrate that this alternative pathway for L1 insertion has been active in recent human evolution and …

A Small-Scale 3d Imaging Platform For Algorithm Performance Evaluation, Steven A. James

Theses and Dissertations

In recent years, world events have expedited the need for the design and application of rapidly deployable airborne surveillance systems in urban environments. Fast and effective use of the surveillance images requires accurate modeling of the terrain being surveyed. The process of accurately modeling buildings, landmarks, or other items of interest on the surface of the earth, within a short lead time, has proven to be a challenging task. One approach of high importance for countering this challenge and accurately reconstructing 3D objects is through the employment of airborne 3D image acquisition platforms. While developments in this arena have significantly …
