Space-based lidar measurements of global ocean carbon stocks

Creator:: Behrenfeld, Michael J., Hu, Yongxiang, Hostetler, Chris A., Dall’Olmo, Giorgio, Rodier, Sharon D., Hair, John W., and Trepte, Charles R.
Abstract:: Global ocean phytoplankton biomass (C-phyto) and total particulate organic carbon (POC) stocks have largely been characterized from space using passive ocean color measurements. A space-based light detection and ranging (lidar) system can provide valuable complementary observations for C-phyto and POC assessments, with benefits including day-night sampling, observations through absorbing aerosols...

Progress report II: Restoring prairies: A synthesis of studies on vegetation and invasive species in support of effective management (Year two)

Creator:: Clark, Deborah Louise, 1950- and Wilson, Mark V.
Abstract:: Willamette Valley wetland and upland prairies are some of the most endangered ecosystems in the United States, and provide habitat for many federally listed species. Because these are dynamic systems, subject to ecological succession and invasion by aggressive non-native species, prairies require active management to maintain management goals. This is...

Gramene database in 2010: updates and extensions

Creator:: Youens-Clark, Ken, Buckler, Ed, Casstevens, Terry, Chen, Charles, DeClerck, Genevieve, Derwent, Paul, Dharmawardhana, Palitha, Jaiswal, Pankaj, Kersey, Paul, Karthikeyan, A. S., Lu, Jerry, McCouch, Susan R., Ren, Liya, Spooner, William, Stein, Joshua C., Thomason, Jim, Wei, Sharon, and Ware, Doreen
Abstract:: Now in its 10th year, the Gramene database (http://www.gramene.org) has grown from its primary focus on rice, the first fully-sequenced grass genome, to become a resource for major model and crop plants including Arabidopsis, Brachypodium, maize, sorghum, poplar and grape in addition to several species of rice. Gramene began with...

Latent homology and convergent regulatory evolution underlies the repeated emergence of yeasts

Creator:: Nagy, László G., Ohm, Robin A., Kovács, Gábor M., Floudas, Dimitrios, Riley, Robert, Gácser, Attila, Sipiczki, Mátyás, Davis, John M., Doty, Sharon L., de Hoog, G Sybren, Lang, B. Franz, Spatafora, Joseph W., Martin, Francis M., Grigoriev, Igor V., and Hibbett, David S.
Abstract:: Convergent evolution is common throughout the tree of life, but the molecular mechanisms causing similar phenotypes to appear repeatedly are obscure. Yeasts have arisen in multiple fungal clades, but the genetic causes and consequences of their evolutionary origins are unknown. Here we show that the potential to develop yeast forms...

Yield responses of invasive grasses to carbon doses

Creator:: Brunson, Jessi L.
Abstract:: The sagebrush steppe ecosystem of the northern Great Basin is severely degraded and continues to decline due in large part to the invasive, non-native annual grasses Bromus tectorum L. (cheatgrass) and Taeniatherum caput-medusae (L.) Nevski (medusahead). Restoration of invasive-dominated areas is difficult, but can be enhanced by adding a carbon...

Distribution of Phytophthora rubi and Pratylenchus penetrans in Pacific Northwest Red Raspberry (Rubus idaeus) Fields

Creator:: Kroese, Duncan R.
Abstract:: The Pacific Northwest produces over 95% of the nation’s processed red raspberries, valued at over $65 million. Two of the major soilborne pathogens effecting the production of raspberry in this region are the oomycete Phytophthora rubi, which causes root rot in red raspberry plants, and the plant-parasitic nematode Pratylenchus penetrans,...

Development of Quantitative PCR Assays to Aid in Root-knot Nematode (Meloidogyne spp.) Diagnostics and Resistance Breeding Efforts in the Pacific Northwest

Creator:: Soule, Michelle L.
Abstract:: In the Pacific Northwest (PNW), the two most common root-knot nematodes are Meloidogyne hapla and Meloidogyne chitwoodi. These nematodes can infect a wide variety of crops and can cause significant losses. Currently, it is common for the field of nematology to use labor-intensive microscopy to identify plant-parasitic nematodes based on...

Biological Soil Crusts of the Great Basin : An Examination of their Distribution, Recovery from Disturbance and Restoration

Creator:: Condon, Lea A.
Abstract:: We are at risk of losing the sagebrush steppe in the floristic Great Basin to the invasion of Bromus tectorum L., cheatgrass. The floristic Great Basin includes the Central Basin and Range, the Northern Basin and Range, and the Snake River Plain. The Great Basin receives most of its precipitation...

The disease cycle of side rot of pear, caused by Phialophora malorum

Creator:: Sugar, David
Abstract:: Potential sources of inoculum of Phialophora malorum were investigated. P. malorum was found to be a soil-borne fungus whose role as a postharvest pathogen of pear is dependent upon passive dispersal with infested soil. P. malorum survived in soil under a wide range of conditions, with greatest survival in cool,...

Insights into Novel Non-Fumigant Nematicides: Physiological and Cellular Responses of Meloidogyne Incognita and Other Plant-Parasitic Nematodes

Creator:: Wram, Catherine L.
Abstract:: Plant-parasitic nematodes (PPN) pose a severe threat to crop production with the economic losses due to nematode parasitism in excessive of US$ 80 billion each year. Meloidogyne incognita, a globally distributed pest with a diverse host range, contributes significantly to this economic loss. The most reliable way to manage PPN...
