North Atlantic right whale habitat in the lower Bay of Fundy and on the SW Scotian Shelf during 1999–2001

Creator:: Baumgartner, Mark F., Cole, Tim V. N., Clapham, Phillip J., and Mate, Bruce R.
Abstract:: Simultaneous visual and oceanographic surveys were conducted in the lower Bay of Fundy and in Roseway Basin of the SW Scotian Shelf during the summers of 1999 to 2001 to investigate the physical and biological oceanographic factors associated with North Atlantic right whale occurrence. Sightings of right whales were recorded...

Minimizing Crop Damage Through Understanding Relationships Between Pyrethrum Phenology and Ray Blight Disease Severity

Creator:: Pethybridge, Sarah J., Gent, David H., Groom, Tim, and Hay, Frank S.
Abstract:: The most damaging foliar disease of pyrethrum in Australia is ray blight caused by Stagonosporopsis tanaceti. The probability of growers incurring economic losses caused by this disease has been substantially reduced by the implementation of a prophylactically applied spring fungicide program. This has been traditionally initiated when 50% of the...

Bird community responses to cattle stocking rates in a Pacific Northwest bunchgrass prairie

Creator:: Johnson, Tracey N., Kennedy, Patricia L., DelCurto, Tim, and Taylor, Robert V.
Abstract:: In 2006–2010, effects of four different cattle stocking rates (0, 14.4, 28.8, and 43.2 animal unit months) were compared, representing 0%, 20%, 32%, and 46% utilization of vegetation by domestic livestock, on vegetation structure (as indexed by visual obstruction), and songbird population and apparent nest density, community composition, and diversity...

Structure of offshore flow

Creator:: Vickers, Dean, Mahrt, L., Sun, Jielun, and Crawford, Tim
Abstract:: The horizontal and vertical structure of the mean flow and turbulent fluxes are examined using aircraft observations taken near a barrier island on the east coast of the United States during offshore flow periods. The spatial structure is strongly influenced by the surface roughness and surface temperature discontinuities at the...

Stocking Rate and Fuels Reduction Effects on Beef Cattle Diet Composition and Quality

Creator:: Clark, Abe, DelCurto, Tim, Vavra, Martin, and Dick, Brian L.
Abstract:: An experiment was conducted to evaluate the influence of forest fuels reduction on diet quality, botanical composition, relative preference, and foraging efficiency of beef cattle grazing at different stocking rates. A split plot factorial design was used, with whole plots (3 ha) being fuel reduced or no treatment (control), and...

The effects of venting and decompression on Yellow Tang (Zebrasoma flavescens) in the marine ornamental aquarium fish trade

Creator:: Munday, Emily S., Tissot, Brian N., Heidel, Jerry R., and Miller-Morgan, Tim
Abstract:: Each year, over 45 countries export 30 million fish from coral reefs as part of the global marine ornamental aquarium trade. This catch volume is partly influenced by collection methods that cause mortality. Barotrauma in fish resulting from forced ascent from depth can contribute to post-collection mortality. However, implementing decompression...

Trends in Caspian Tern Nesting and Diet in San Francisco Bay: Conservation Implications for Terns and Salmonids

Creator:: Collis, Ken, Roby, Daniel D., Larson, Keith W., Adrean, Lindsay J., Nelson, S. Kim, Evans, Allen F., Hostetter, Nathan, Battaglia, Dan, Lyons, Donald E., Marcella, Tim, and Patterson, Allison
Abstract:: Colony size, nesting ecology and diet of Caspian Terns (Hydroprogne caspia) were investigated in the San Francisco Bay area (SFBA) during 2003-2009 to assess the potential for conservation of the tern breeding population and possible negative effects of predation on survival of juvenile salmonids (Oncorhynchus spp.). Numbers of breeding Caspian...

High‐resolution measurements of dissolved organic carbon in the Arctic Ocean by in situ fiber‐optic spectrometry

Creator:: Guay, Christopher K., Klinkhammer, Gary P., Falkner, Kelly, Benner, Ronald, Coble, Paula G., Whiteledge, Terry E., Black, Brenda, Bussell, F. Joseph, and Wagner, Tim A.
Abstract:: Here we report results from an extensive survey of dissolved organic carbon (DOC) in the Arctic Ocean, which was achieved by means of a high-resolution, in situ UV fluorometer deployed on a nuclear submarine. Based on a strong linear correlation observed between fluorescence (320 nm excitation, 420 nm emission) and...

Magmatism in the Bransfield Basin: Rifting of the South Shetland Arc?

Creator:: Fretzdorff, Susanne, Worthington, Tim J., Haase, Karsten M., Hekinian, Roger, Franz, Leander, Keller, Randall A., and Stoffers, Peter
Abstract:: Bransfield Basin is an actively extending marginal basin separating the inactive South Shetland arc from the northern Antarctic Peninsula. Rift-related volcanism is widespread throughout the central Bransfield Basin, but the wider eastern Bransfield Basin was previously unsampled. Lavas recovered from the eastern subbasin form three distinct groups: (1) Bransfield Group...

Potential limitations of NRC in predicting energetic requirements of beef females within western U.S. grazing systems

Creator:: Petersen, M. K., Mueller, C. J., Mulliniks, J. T., Roberts, A. J., DelCurto, Tim, and Waterman, R. C.
Abstract:: Assessment of beef cow energy balance and efficiency in grazing-extensive rangelands has occurred on a nominal basis over short time intervals and has not accounted for the complexity of metabolic and digestive responses; behavioral adaptations to climatic, terrain, and vegetation variables; and documentation of the effects of nutrient form and...
