The Future of Oregon's Agricultural Land

Creator:: Brekken, Christy Anderson, Gwin, Lauren, Horst, Megan, McAdams, Nellie, Martin, Sheila, and Stephenson, Garry
Abstract:: Sixty-four percent of Oregon's farmland is expected to change hands in the next 20 years, yet many Oregon farmers are unprepared for succession. Simultaneously, beginning farmers are finding it harder to start farmers because of dramatically increasing land prices. These distinct but interwined challenges are addressed in a new research...

An evaluation of orange and clear traps with pear ester to monitor codling moth (Lepidoptera: Tortricidae) in apple orchards, Evaluación de trampas naranjas y transparentes con éster de pera para monitorear la polilla de la manzana (Lepidoptera: Tortricidae) en huertos de manzano

Creator:: Barros-Parada, Wilson, Knight, Alan L., Basoalto, Esteban, and Fuentes-Contreras, Eduardo
Abstract:: Studies were conducted to evaluate the use of several trap-lure combinations to improve the monitoring of codling moth, Cydia pomonella (L.) (Lepidoptera: Tortricidae), in apple, Malus domestica Bordk. The treatments involved the use of clear, orange, and white traps baited with one or more of the following attractants: the major...

Complete genome sequence of Nitrosomonas sp. Is79, an ammonia oxidizing bacterium adapted to low ammonium concentrations

Creator:: Bollmann, Annette, Sedlacek, Christopher J., Norton, Jeanette, Laanbroek, Hendrikus J., Suwa, Yuichi, Stein, Lisa Y., Klotz, Martin G., Arp, Daniel J., Sayavedra-Soto, Luis, Lu, Megan, Bruce, David, Detter, Chris, Tapia, Roxanne, Han, James, Woyke, Tanja, Pitluck, Sam, Pennacchio, Len, Nolan, Matt, Land, Miriam L., Huntemann, Marcel, Deshpande, Shweta, Han, Cliff, Chen, Amy, Kyrpides, Nikos, Movromatis, Konstantinos, Markowitz, Victor, Szeto, Ernest, Ivonova, Natalia, Mikhailova, Natalia, Pagani, Ioanna, Pati, Amrita, Peters, Lin, Ovchinnikova, Galina, Goodwin, Lynne A., and Lucas, Susan M.
Abstract:: Nitrosomonas sp. Is79 is a chemolithoautotrophic ammonia-oxidizing bacterium that belongs to the family Nitrosomonadaceae within the phylum Proteobacteria. Ammonia oxidation is the first step of nitrification, an important process in the global nitrogen cycle ultimately resulting in the production of nitrate. Nitrosomonas sp. Is79 is an ammonia oxidizer of high...

Responsible Aquaculture in 2050: Valuing Local Conditions and Human Innovations Will Be Key to Success

Creator:: Diana, James S., Egna, Hillary S., Chopin, Thierry, Peterson, Mark S., Cao, Ling, Pomeroy, Robert, Verdegem, Marc, Slack, William T., Bondad-Reantaso, Melba G., and Cabello, Felipe
Abstract:: As aquaculture production expands, we must avoid mistakes made during increasing intensification of agriculture. Understanding environmental impacts and measures to mitigate them is important for designing responsible aquaculture production systems. There are four realistic goals that can make future aquaculture operations more sustainable and productive: (I) improvement of management practices...

Genome Sequence of Nitrosomonas sp. Strain AL212, an Ammonia-Oxidizing Bacterium Sensitive to High Levels of Ammonia

Creator:: Yuichi, Suwa, Norton, Jeanette M., Bollmann, Annette, Klotz, Martin G., Stein, Lisa Y., Laanbroek, Hendrikus J., Arp, Daniel J., Goodwin, Lynne A., Chertkov, Olga, Held, Brittany, Bruce, David, Detter, J. Chris, Detter, Janine C., Tapia, Roxanne, and Han, Cliff S.
Abstract:: Nitrosomonas sp. strain AL212 is an obligate chemolithotrophic ammonia-oxidizing bacterium (AOB) that was originally isolated in 1997 by Yuichi Suwa and colleagues. This organism belongs to Nitrosomonas cluster 6A, which is characterized by sensitivity to high ammonia concentrations, higher substrate affinity (lower K[subscript m]), and lower maximum growth rates than...

Landscape-Scale Rehabilitation of Medusahead (Taeniatherum caput-medusae)- Dominated Sagebrush Steppe

Creator:: Sheley, Roger L., Vasquez, Edward A., Chamberlain, Anna-Marie, and Smith, Brenda S.
Abstract:: Producers facing infestations of invasive annual grasses regularly voice the need for practical revegetation strategies that can be applied across broad landscapes. Our objective was to determine the potential for scaling up the single-entry approach for revegetating medusahead-infested rangeland to broader, more heterogeneous landscape-scale revegetation of winter annual grass–infested rangeland....

Developmental Time, Longevity, and Lifetime Fertility of Three Introduced Parasitoids of the Mealybug Paracoccus marginatus (Hemiptera: Pseudococcidae)

Creator:: Amarasekare, Kaushalya G., Mannion, Catharine M., and Epsky, Nancy D.
Abstract:: Developmental time, longevity, and lifetime fertility of three previously introduced parasitoids (Acerophagus papayae Noyes and Schauff, Anagyrus loecki Noyes and Menezes, and Pseudleptomastix mexicana Noyes and Schauff) (Hymenoptera: Encyrtidae) of the mealybug Paracoccus marginatus Williams and Granara de Willink (Hemiptera: Pseudococcidae) were studied in the laboratory to understand the outcome...

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...

A survey of scale insects (Sternorryncha: Coccoidea) occurring on table grapes in South Africa

Creator:: Walton, Vaughn M., Krüger, Kerstin, Saccaggi, Davina L., and Millar, Ian M.
Abstract:: Increasing international trade and tourism have led to an increase in the introduction of exotic pests that pose a considerable economic threat to the agro-ecosystems of importing countries. Scale insects (Sternorryncha: Coccoidea) may be contaminants of export consignments from the South African deciduous fruit industry to the European Union, Israel,...

Integrating precipitation, grazing, past effects and interactions in long-term vegetation change

Creator:: Morris, Christo, Badik, Kevin J., Morris, Lesley R., and Weltz, Mark A.
Abstract:: Determining the causes of vegetation change in arid and semi-arid environments can be difficult and may involve multiple factors, including disturbance, inter-annual climatic variation, soils, effects from years past and interactions between these factors. Theoretical models describing vegetation change in these systems have generally focused on a single aspect as...
