    • Density dependence in demography and dispersal generates fluctuating invasion speeds 

      Sullivan, Lauren L.; Li, Bingtuan; Miller, Tom E. X.; Neubert, Michael G.; Shaw, Allison K. (2017-04)
      Mitigating the spread of invasive species remains difficult—substantial variability in invasion speed is increasingly well-documented, but the sources of this variability are poorly understood. We report a mechanism for ...
    • Fire increases invasive spread of Molinia caerulea mainly through changes in demographic parameters 

      Jacquemyn, Hans; Brys, Rein; Neubert, Michael G. (Ecological Society of America, 2005-12)
      We investigated the effects of fire on population growth rate and invasive spread of the perennial tussock grass Molinia caerulea. During the last decades, this species has invaded heathland communities in Western Europe, ...
    • Sex differences and Allee effects shape the dynamics of sex-structured invasions 

      Shaw, Allison K.; Kokko, Hanna; Neubert, Michael G. (2017-02)
      The rate at which a population grows and spreads can depend on individual behaviour and interactions with others. In many species with two sexes, males and females differ in key life history traits (e.g. growth, survival, ...
    • Sex-biased dispersal and the speed of two-sex invasions 

      Miller, Tom E. X.; Shaw, Allison K.; Inouye, Brian D.; Neubert, Michael G. (University of Chicago, 2011-04-07)
      Population models that combine demography and dispersal are important tools for forecasting the spatial spread of biological invasions. Current models describe the dynamics of only one sex (typically females). Such models ...
