Microsatellite analysis to estimate realized dispersal distance in Phragmites australis

摘要: An understanding of the mean and maximum dispersal distances target species subsequent scaling management efforts to distance can be key in slowing, containing, or eradicating invasive species. However, is often difficult measure. Patterns genetic relatedness interpreted understand realized distances, which then applied management. We analyzed patterns microsatellite using Mantel correlograms used them estimate for wetland grass, Phragmites australis. found that declined quickly with increasing distance, decreasing level subestuary by 100 m nearly zero 500 m. interpret this indicate most <100 m very little extends beyond This suggests P. australis may need consider from stands up 500 m an area being managed, perhaps at scale whole subestuaries. Results study demonstrate analysis develop landscape-scale approaches
