  • Quantifying Microstegium vimineum Seed Movement by Non-Riparian Water Dispersal Using an Ultraviolet-Marking Based Recapture Method 

    Tekiela, Daniel R.; Barney, Jacob N. (PLOS, 2013-09-12)
    Microstegium vimineum is a shade tolerant annual C4 invasive grass in the Eastern US, which has been shown to negatively impact species diversity and succession in hardwood forests. To date, empirical studies have shown ...
  • Wind-driven spume droplet production and the transport of Pseudomonas syringae from aquatic environments 

    Pietsch, Renee B.; Grothe, Hinrich; Hanlon, Regina; Powers, Craig W.; Jung, Sunghwan; Ross, Shane D.; Schmale, David G. (PeerJ, 2018-09-26)
    Natural aquatic environments such as oceans, lakes, and rivers are home to a tremendous diversity of microorganisms. Some may cross the air-water interface within droplets and become airborne, with the potential to impact ...
  • Coordinated Sampling of Microorganisms Over Freshwater and Saltwater Environments Using an Unmanned Surface Vehicle (USV) and a Small Unmanned Aircraft System (sUAS) 

    Powers, Craig W.; Hanlon, Regina; Grothe, Hinrich; Prussin, Aaron J. II; Marr, Linsey C.; Schmale, David G. III (Frontiers, 2018-08-15)
    Biological aerosols (bioaerosols) are ubiquitous in terrestrial and aquatic environments and may influence cloud formation and precipitation processes. Little is known about the aerosolization and transport of bioaerosols ...
  • Multi-Phase US Spread and Habitat Switching of a Post-Columbian Invasive, Sorghum halepense 

    Sezen, U. Uzay; Barney, Jacob N.; Atwater, Daniel Z.; Pederson, Gary A.; Pederson, Jeffrey F.; Chandler, J. Mike; Cox, T. Stan; Cox, Sheila; Dotray, Peter; Kopec, David; Smith, Steven E.; Schroeder, Jill; Wright, Steven D.; Jiao, Yuannian; Kong, Wenqian; Goff, Valorie; Auckland, Susan; Rainville, Lisa K.; Pierce, Gary J.; Lemke, Cornelia; Compton, Rosana; Phillips, Christine; Kerr, Alexandra; Mettler, Matthew; Paterson, Andrew H. (PLOS, 2016-10-18)
    Johnsongrass (Sorghum halepense) is a striking example of a post-Columbian founder event. This natural experiment within ecological time-scales provides a unique opportunity for understanding patterns of continent-wide ...
  • Weed Management in 2050: Perspectives on the Future of Weed Science 

    Westwood, James H.; Charudattan, Raghavan; Duke, Stephen O.; Fennimore, Steven A.; Marrone, Pam; Slaughter, David C.; Swanton, Clarence; Zollinger, Richard (Weed Science Society of America, 2018-02-21)
    The discipline of weed science is at a critical juncture. Decades of efficient chemical weed control have led to a rise in the number of herbicide-resistant weed populations, with few new herbicides with unique modes of ...

  • Comparative genomics of Pseudomonas syringae pathovar tomato reveals novel chemotaxis pathways associated with motility and plant pathogenicity 

    Clarke, Christopher R.; Hayes, Byron W.; Runde, Brendan J.; Markel, Eric; Swingle, Bryan M.; Vinatzer, Boris A. (PeerJ, 2016-10-25)
    The majority of bacterial foliar plant pathogens must invade the apoplast of host plants through points of ingress, such as stomata or wounds, to replicate to high population density and cause disease. How pathogens navigate ...
  • Modification of the Mycotoxin Deoxynivalenol Using Microorganisms Isolated from Environmental Samples 

    Wilson, NM; McMaster, N; Gantulga, D; Soyars, C; McCormick, SP; Knott, K; Senger, RS; Schmale, DG (MDPI, 2017-04-01)
    The trichothecene mycotoxin deoxynivalenol (DON) is a common contaminant of wheat, barley, and maize. New strategies are needed to reduce or eliminate DON in feed and food products. Microorganisms from plant and soil samples ...
  • Herbicide injury induces DNA methylome alterations in Arabidopsis 

    Kim, G; Clarke, CR; Larose, H; Tran, HT; Haak, DC; Zhang, L; Askew, S; Barney, J; Westwood, JH (Peerj Inc, 2017-07-20)
    The emergence of herbicide-resistant weeds is a major threat facing modern agriculture. Over 470 weedy-plant populations have developed resistance to herbicides. Traditional evolutionary mechanisms are not always sufficient ...
  • Climatic niche shifts are common in introduced plants 

    Atwater, Daniel Z.; Ervine, Carissa; Barney, Jacob N. (Nature, 2017-12-04)
    Our understanding of how climate influences species distributions and our ability to assess the risk of introduced species depend on the assumption that species’ climatic niches remain stable across space and time. While ...
