Patterns of vertical distribution and migration of zooplankton at Ocean Station “P”

Creator:: Marlowe, Christopher J. and Miller, Charles B.
Abstract:: Stratified bongo net samples taken at depths between 0 and 500 m at Ocean Station “P” in the subarctic Pacific in early July 1971 have been analyzed to determine the vertical structure of the zooplankton community. Distributions for 99 categories of animals have been grouped by factor analysis into five...

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...

Variability in the Southerly Flow into the Eastern Pacific ITCZ

Creator:: de Szoeke, Simon P. and Bretherton, Christopher S.
Abstract:: During boreal summer and fall, there is a strong southerly boundary layer flow across the equator into the east Pacific intertropical convergence zone (ITCZ). The modulation of this flow on synoptic to seasonal time scales is studied using an index of meridional pressure difference between the equator and the ITCZ...

EPIC 95°W Observations of the Eastern Pacific Atmospheric Boundary Layer from the Cold Tongue to the ITCZ

Creator:: de Szoeke, Simon P. and Bretherton, Christopher S.
Abstract:: The atmospheric boundary layer (ABL) along 95°W in the eastern equatorial Pacific during boreal autumn is described using data from the East Pacific Investigation of Climate (EPIC) 2001, with an emphasis on the evolution of the thermodynamic ABL properties from the cold tongue to the cold-advection region north of the...

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...
