Consequences of an Allee Effect in the Invasion of a Pacific Estuary by Spartina alterniflora

Results from both a spatially explicit stochastic simulation model and a spatially implicit deterministic model show that a weak Allee effect can slow the spread of an invasive plant, Spartina alterniflora, in a Pacific Coast estuary. The mean rate of spread with the Allee effect is ~19%; removing t...
