Skill progression demonstrated by users in the Scratch animation environment

Creator:: Scaffidi, Christopher and Chambers, Christopher
Abstract:: The Scratch environment exemplifies a tool+community approach to teaching elementary programming skills, as it includes a website where users can publish, discuss, and organize animations that are programs. To explore this environment’s effectiveness for helping people to develop programming skills, we performed a quantitative analysis of 250 randomly-selected users’ data,...

Potential effects of sea-level rise on plant productivity: species-specific responses in northeast Pacific tidal marshes

Creator:: Janousek, Christopher
Abstract:: Coastal wetland plants are adapted to varying degrees of inundation. However, functional relationships between inundation and productivity are poorly characterized for most species. Determining species-specific tolerances to inundation is necessary to evaluate sea-level rise (SLR) effects on future marsh plant community composition, quantify organic matter inputs to marsh accretion, and...

Deoxyribonucleotides as Genetic and Metabolic Regulators

Creator:: Mathews, Christopher K.
Abstract:: For more than 35 years we have known that the accuracy of DNA replication is controlled in large part by the relative concentrations of the four canonical deoxyribonucleoside 5'-triphosphates (dNTPs) at the replisome. Since this field was last reviewed, about eight years ago, there has been increased understanding of the...

Durable resistance: A key to sustainable management of pathogens and pests

Creator:: Mundt, Christopher C.
Abstract:: This review briefly addresses what has been learned about resistance durability in recent years, as well as the questions that still remain. Molecular analyses of major gene interactions have potential to contribute to both breeding for resistance and improved understanding of virulence impacts on pathogen fitness. Though the molecular basis...

Polycyclic aromatic hydrocarbons as skin carcinogens: Comparison of benzo[a]pyrene, dibenzo[def,p]chrysene and three environmental mixtures in the FVB/N mouse

Creator:: Siddens, Lisbeth K., Larkin, Andrew, Krueger, Sharon K., Bradfield, Christopher A., Waters, Katrina M., Tilton, Susan C., Pereira, Cliff B., Lohr, Christiane V., Arlt, Volker M., Phillips, David H., Williams, David E., and Baird, William M.
Abstract:: The polycyclic aromatic hydrocarbon (PAH), benzo[a]pyrene (BaP), was compared to dibenzo[def,p]chrysene (DBC) and combinations of three environmental PAH mixtures (coal tar, diesel particulate and cigarette smoke condensate) using a two stage, FVB/N mouse skin tumor model. DBC (4 nmol) was most potent, reaching 100% tumor incidence with a shorter latency...

Development of a New USDA Plant Hardiness Zone Map for the United States

Creator:: Daly, Christopher, Widrlechner, Mark P., Halbleib, Michael D., Smith, Joseph I., and Gibson, Wayne P.
Abstract:: In many regions of the world, the extremes of winter cold are a major determinant of the geographic distribution of perennial plant species and of their successful cultivation. In the United States, the U.S. Department of Agriculture (USDA) Plant Hardiness Zone Map (PHZM) is the primary reference for defining geospatial...

Growth, survival, and habitat use of naturally reared and hatchery steelhead fry in streams: effects of an enriched hatchery rearing environment

Creator:: Tatara, Christopher P., Riley, Stephen C., and Scheurer, Julie A.
Abstract:: After hatchery-reared salmonids are released into the wild, their survival and performance are frequently lower than those of wild conspecifics. Additionally, negative effects of hatchery fish on wild fish are cited as factors affecting the recovery of salmonid populations. Alternative hatchery rearing environments and release practices have been proposed to...

Geostrophic Velocity Measurement Techniques for the Meridional Overturning Circulation and Meridional Heat Transport in the South Atlantic

Creator:: Perez, Renellys C., Garzoli, Silvia L., Meinen, Christopher S., and Matano, Ricardo P.
Abstract:: Two ocean general circulation models are used to test the ability of geostrophic velocity measurement systems to observe the meridional overturning circulation (MOC) and meridional heat transport (MHT) in the South Atlantic. Model sampling experiments are conducted at five latitudes (between 15° and 34.5°S) spanning the range of extratropical current...

Horticultural Applications of a Newly Revised USDA Plant Hardiness Zone Map

Creator:: Widrlechner, Mark P., Daly, Christopher, Keller, Markus, and Kaplan, Kim
Abstract:: The accurate prediction of winter injury caused by low-temperature events is a key component of the effective cultivation of woody and herbaceous perennial plants. A common method employed to visualize geographic patterns in the severity of low-temperature events is to map a climatological variable that closely correlates with plant survival....

Docosahexaenoic acid attenuates Western diet-induced hepatic fibrosis in Ldlr(-/-) mice by targeting the TGFβ-Smad3 pathway

Creator:: Lytle, Kelli A., Depner, Christopher M., Wong, Carmen P., and Jump, Donald B.
Abstract:: DHA (22:6,ω3), but not EPA (20:5,ω3), attenuates Western diet (WD)-induced hepatic fibrosis in a Ldlr[superscript −/−] mouse model of nonalcoholic steatohepatitis. We examined the molecular basis for the differential effect of dietary EPA and DHA on WD-induced hepatic fibrosis. DHA was more effective than EPA at preventing WD-induced effects on...
