      Miller, Corwin; Kong, Jiayi; Tran, Truc T.; Arias, Cesar A.; Saxer, Gerda; Shamoo, Yousif (2013)
      With increasing numbers of hospital-acquired antibiotic resistant infections each year and staggering health care costs, there is a clear need for new antimicrobial agents, as well as novel strategies to extend their ...
    • Amino Acid Repeats Cause Extraordinary Coding Sequence Variation in the Social Amoeba Dictyostelium discoideum 

      Scala, Clea; Tian, Xiangjun; Mehdiabadi, Natasha J.; Smith, Margaret H.; Saxer, Gerda; Stephens, Katie; Buzombo, Prince; Strassmann, Joan E.; Queller, David C. (2012-09)
      Protein sequences are normally the most conserved elements of genomes owing to purifying selection to maintain their functions. We document an extraordinary amount of within-species protein sequence variation in the model ...
    • Balancing anti-herbivore benefits and anti-pollinator costs of defensive mutualists 

      Ohm, Johanna R.; Miller, Tom E.X. (2014)
      Quantifying costs and benefits of ostensibly mutualistic interactions is an important step toward understanding their evolutionary trajectories. In food-for-protection interactions between ants and extrafloral nectar ...
    • Chinese Tallow Trees (Triadica sebifera) from the Invasive Range Outperform Those from the Native Range with an Active Soil Community or Phosphorus Fertilization 

      Zhang, Ling; Zhang, Yaojun; Wang, Hong; Zou, Jianwen; Siemann, Evan (2013)
      Two mechanisms that have been proposed to explain success of invasive plants are unusual biotic interactions, such as enemy release or enhanced mutualisms, and increased resource availability. However, while these mechanisms ...

      Lu, Xinmin; Siemann, Evan; He, Minyan; Wei, Hui; Shao, Xu; Ding, Jianqing (2015)
      Climate change may shift interactions of invasive plants, herbivorous insects and native plants, potentially affecting biological control efficacy and non-target effects on native species. Here, we show how climate warming ...
    • Consequences of sex-selective harvesting and harvest refuges in experimental meta-populations 

      Snyder, Kate T.; Freidenfelds, Nicole A.; Miller, Tom E.X. (2013)
      Harvesting for food or sport is often non-random with respect to demographic state, such as size or life stage. The population- level consequences of such selective harvesting depend upon which states are harvested and how ...
    • Conspecific Plasticity and Invasion: Invasive Populations of Chinese Tallow (Triadica sebifera)ᅠHave Performance Advantage over Native Populations Only in Low Soil Salinity 

      Chen, Leiyi; Tiu, Candice J.; Peng, Shaolin; Siemann, Evan (2013)
      Global climate change may increase biological invasions in part because invasive species may have greater phenotypic plasticity than native species. This may be especially important for abiotic stresses such as salt ...

    • Individual and combined effects of two types of phenological shifts on predator–prey interactions 

      Rasmussen, Nick L.; Rudolf, Volker H.W. (2016)
