Hydraulic redistribution by two semi-arid shrub species: Implications for Sahelian agro-ecosystems

Creator:: Kizito, F., Dragila, M. I., Sene, M., Brooks, J. R., Meinzer, Frederick C., Diedhiou, I., Diouf, M., Lufafa, A., Dick, R. P., Selker, J., and Cuenca, R.
Abstract:: Hydraulic redistribution is the process of passive water movement from deeper moist soil to shallower dry soil layers using plant roots as conduits. Results from this study indicate that this phenomenon exists among two shrub species (Guiera senegalensis and Piliostigma reticulatum) that co-exist with annual food crops in Sahelian agro-ecosystems....

Water uptake in biochars: The roles of porosity and hydrophobicity

Creator:: Gray, Myles, Johnson, Mark G., Dragila, Maria I., and Kleber, Markus
Abstract:: We assessed the effects of porosity and hydrophobicity on water uptake by biochars. Biochars were produced from two feedstocks (hazelnut shells and Douglas fir chips) at three production temperatures (370°C, 500°C, and 620°C). To distinguish the effects of porosity from the effects of hydrophobicity, we compared uptake of water to...

The “Fast Fish” Campaign in Japan and Consumers’ Consciousness of Marine Environmental Preservation

Creator:: Oishi, Taro, Tatefuku, I., and Mochizuki, M.
Abstract:: The “Fast Fish” campaign is a policy promoted by the Ministry of Agriculture, Forestry and Fisheries in Japan. The term “Fast Fish” refers to fish products that are boneless and easy to prepare. Our study examined the campaign’s influence on consumer consciousness of marine environmental preservation in Japan, which is...

Multi-scale spatial controls of understory vegetation in Douglas-fir–western hemlock forests of western Oregon, USA

Creator:: Burton, Julia I., Ganio, Lisa M., and Puettmann, Klaus J.
Abstract:: Forest understory vegetation is influenced by broad-scale variation in climate, intermediate-scale variation in topography, disturbance and neighborhood interactions. However, little is known about how these multi-scale controls interact to influence observed spatial patterns. We examined relationships between the aggregated cover of understory plant species (%C[subscript U]) and multi-scale controls using...

Population Dynamics of the Beet Leafhopper in Northeastern Oregon and Incidence of the Beet Leafhopper-Transmitted Virescence Agent Phytoplasma

Creator:: Crosslin, J. M., Rondon, Silvia I., and Hamm, P. B.
Abstract:: Beet leafhoppers were collected weekly on yellow sticky traps placed at 36 locations in Morrow and Umatilla Counties in northeastern Oregon in April through November 2007, 2008, and 2009. Insects were counted, collected, and a subset of the insects was tested for the presence of the beet leafhopper-transmitted virescence agent...

Observations of Internal Tides on the Oregon Continental Slope

Creator:: Martini, Kim I., Alford, Matthew H., Kunze, Eric, Kelly, Samuel M., and Nash, Jonathan D.
Abstract:: A complex superposition of locally forced and shoaling remotely generated semidiurnal internal tides occurs on the Oregon continental slope. Presented here are observations from a zonal line of five profiling moorings deployed across the continental slope from 500 to 3000 m, a 24-h expendable current profiler (XCP) survey, and five...
