Priority effects can lead to underestimation of dispersal and invasion potential

Banks, Samuel; Waters, Jonathan; Fraser, Ceridwen


Molecular analyses are frequently used to assess biological gene flow and dispersal, yet recent data suggest that the operation of density-dependent priority effects often leads to underestimation of species movement patterns and associated invasive potential. Although individual movement is broadly considered to promote connectivity among populations, emerging genetic evidence on a range of scales indicates that it often fails to do so; instead, it can be a strategy that allows first...[Show more]
