Genome Size Scaling Through Phenotype Space, Charles A. Knight, Jeremy M. Beaulieu
Genome Size Scaling Through Phenotype Space, Charles A. Knight, Jeremy M. Beaulieu
Biological Sciences
Background and Aims Early observations that genome size was positively correlated with cell size formed the basis of hypothesized consequences of genome size variation at higher phenotypic scales. This scaling was supported by several studies showing a positive relationship between genome size and seed mass, and various metrics of growth and leaf morphology. However, many of these studies were undertaken with limited species sets, and often performed within a single genus. Here we seek to generalize the relationship between genome size and the phenotype by examining eight phenotypic traits using large cross-species comparisons involving diverse assemblages of angiosperm and gymnosperm …
Maternal Effects Of Carotenoid Consumption In Guppies (Poecilia Reticulata), Gregory F. Grether, Gita R. Kolluru, K. Lin, M. A. Quiroz, G. Robertson, A. J. Snyder
Maternal Effects Of Carotenoid Consumption In Guppies (Poecilia Reticulata), Gregory F. Grether, Gita R. Kolluru, K. Lin, M. A. Quiroz, G. Robertson, A. J. Snyder
Biological Sciences
1. Carotenoids transferred from mother to offspring may enhance the quality of the offspring. Whether such maternal effects occur in guppies (Poecilia reticulata) has an important bearing on mate preference evolution.
2. By raising female guppies from birth on different dietary carotenoid levels, we examined the pattern of carotenoid allocation to maternal tissue (skin) vs. eggs. Skin carotenoid content was only weakly affected by carotenoid intake while egg carotenoid content was strongly affected.
3. We then tested for effects of maternal carotenoid intake on several measures of offspring quality, including size and condition at birth, juvenile growth rate, …
Language And Responsibility: The Possibilities And Problems Of Poetic Thinking For Environmental Philosophy, Eleanor D. Helms
Language And Responsibility: The Possibilities And Problems Of Poetic Thinking For Environmental Philosophy, Eleanor D. Helms
Philosophy
There is a sense in which poetry can re-inscribe humans in their natural surroundings, but language—even poetic language—is also always problematic. In conversation with and in response to recent works by David Abram, I will delineate at least two ways in which poetic language separates and distinguishes humans from nature. I also argue for the importance of what is implicit or invisible (as opposed to tangible and sensuous). Language is a mode of human responsibility for the world, not just a sign or result of being part of it.

Conjugated Linoleic Acids Alter Body Composition Differently According To Physiological Age In Moulard Ducks, Jeffrey Allen Fesler, Daniel G. Peterson
Conjugated Linoleic Acids Alter Body Composition Differently According To Physiological Age In Moulard Ducks, Jeffrey Allen Fesler, Daniel G. Peterson
Animal Science
Recent developments in the field of lipid biology have shown conjugated linoleic acids (CLA) to have remarkable yet inconsistent metabolic effects in mice, rats, hamsters, chickens, cows, and humans. In particular, effects on lipogenesis vary with tissue, physiological state, and specie. In this study, sub-adult (7 wk) and adult (11 wk) moulard ducks were grouped by age and fed a standard corn-soy based diet supplemented with either 5% soybean oil (control) or 5% CLA isomer mixture (30% 9c,11t, 30% 10t,12c; CLA). Animals were harvested after 3 wk or 6 wk for assessment of body composition including liver, adipose, viscera, and …

The Protracted Holocene Extinction Of California's Flightless Sea Duck (Chendytes Lawi) And Its Implications For The Pleistocene Overkill Hypothesis, Terry L. Jones, Judith F. Porcasi, J. M. Erlandson, H. Dallas, Jr., T. A. Wake, R. Schwaderer
The Protracted Holocene Extinction Of California's Flightless Sea Duck (Chendytes Lawi) And Its Implications For The Pleistocene Overkill Hypothesis, Terry L. Jones, Judith F. Porcasi, J. M. Erlandson, H. Dallas, Jr., T. A. Wake, R. Schwaderer
Social Sciences
Bones of the flightless sea duck (Chendytes lawi) from 14 archaeological sites along the California coast indicate that humans hunted the species for at least 8,000 years before it was driven to extinction. Direct 14C dates on Chendytes bones show that the duck was exploited on the southern California islands as early as ≈ 11,150-10,280 calendar years B.P., and on the mainland by at least 8,500 calendar years B.P. The youngest direct date of 2,720-2,350 calendar years B.P., combined with the absence of Chendytes bones from hundreds of late Holocene sites, suggests that the species was extinct …

Moderate Zinc Restriction Affects Intestinal Health And Immune Function In Lipopolysaccharide-Challenged Mice, Daniel G. Peterson, Angus G. Scrimgeour, James P. Mcclung, Elizabeth A. Koutsos
Moderate Zinc Restriction Affects Intestinal Health And Immune Function In Lipopolysaccharide-Challenged Mice, Daniel G. Peterson, Angus G. Scrimgeour, James P. Mcclung, Elizabeth A. Koutsos
Animal Science
Zinc (Zn) is an essential nutrient that affects immune function, especially within the digestive system, although the underlying mechanisms are not well understood. This study examined the effects of short-term moderate Zn restriction on intestinal health and immune function in lipopolysaccharide (LPS)-challenged mice through plasma cytokine profiling and histological evaluation of intestinal tissue sections. Adult male mice were fed with a Zn-adequate (40 ppm) or a Zn-marginal (4 ppm) diet for 4 weeks, and then a bacterial challenge was simulated by intraperitoneal injection of LPS (10 μg/g body weight [BW]) or saline (control). BW was recorded weekly, and feed intake …
Effects Of Short-Term Exercise And Energy Surplus On Hormones Related To Regulation Of Energy Balance, Todd A. Hagobian, Carrie G. Sharoff, Barry Braun
Effects Of Short-Term Exercise And Energy Surplus On Hormones Related To Regulation Of Energy Balance, Todd A. Hagobian, Carrie G. Sharoff, Barry Braun
Kinesiology and Public Health
Energy surplus raises circulating concentrations of leptin and insulin while lowering plasma ghrelin. Exercise has the opposite effects. The purpose of this study was to determine whether exercise counters the hormonal effects of energy surplus independent of changes in energy balance. To do that, we assessed plasma concentrations of leptin, insulin, and ghrelin at baseline, after overfeeding, and after overfeeding plus exercise. Baseline (B) leptin and insulin concentrations and ghrelin area under the curve were measured during an oral glucose challenge in 9 healthy, active subjects (6 male, 3 female) after 2 days in energy balance without exercise. Measurements were …

Rfid Research And Testing For Packages Of Apparel, Consumer Goods And Fresh Produce In The Retail Distribution Environment, S. P. Singh, M. Mccartney, Jay Singh, R. Clarke
Industrial Technology and Packaging
Radio frequency identification (RFID) is a term used for any device that can be sensed at a distance by radio frequencies with few problems of obstruction. The origins of the term lie in the invention of tags that reflect or retransmit a radiofrequency signal. According to a recent article by Forrester Research, the minimal ‘Slap and Ship’ approach to RFID compliance will cost an individual company between $2 million and $20 million. Because retailers like Wal-Mart plan to share with their suppliers all the RFID-generated data points (from when a case/pallet enters their distribution centre until it leaves their stockroom), …

A Sentence Completion Task To Familiarize Students With Word Problem Structures, Jose A. Montelongo, Roberta Herter
A Sentence Completion Task To Familiarize Students With Word Problem Structures, Jose A. Montelongo, Roberta Herter
Library Scholarship
Marshall (1995) provided a classification scheme for arithmetic word problems. The most frequent types of word problems are the change, group, compare, restate, and vary situations. Change situations tell a story in which there is a change in a measurable quantity of a particular thing. Group word problems ask the solver to use combine members of the same classification before performing a mathematical calculation upon these. Compare situations require a student to complete mathematical calculations upon two or more things and to contrast their quantities for a conclusion. Restate word problems include both a relational statement between two or more …
