Population genetic analysis of Bromus tectorum (Poaceae) indicates recent range expansion may be facilitated by specialist genotypes.

American journal of botany - 1 Mar 2012

Merrill Keith R, Meyer Susan E, Coleman Craig E

Abstract excerpt

PREMISE OF THE STUDY: The mechanisms for range expansion in invasive species depend on how genetic variation is structured in the introduced range. This study examined neutral genetic variation in the invasive annual grass Bromus tectorum in the Intermountain Western United States. Patterns of microsatellite (SSR) genotype distribution in this highly inbreeding species were used to make inferences about the roles...
