Karnal bunt of wheat is one interesting and important example of complexity in invasive potential.
We have modeled the likely impact of an Allee effect, or reduced per capita reproductive success at low populations,
for this pathogen (Garrett and Bowden 2002). We have recently developed a new turning point analysis of empirical data demonstrating the
Allee effect in this system, which provides a general approach for analysis of Allee effects in microbes
that can span wide ranges of population sizes.
