Invasion genetics of a freshwater mussel (Dreissena rostriformis bugensis) in eastern Europe: High gene flow and multiple introductions

Article Abstract:

Six published microsatellite markers are used to survey populations throughout eastern Europe and a range is introduced to identify relationships among potential source populations and introduced ones. Evidence of considerable gene flow among populations is observed and it is found that high gene flow, due to multiple invasions, has facilitated establishment of quagga mussel Dreissena rostriformis bugensis populations in the Volga river system.

Interspecific hybridization among Hieracium species in New Zealand: evidence from flow cytometry

Article Abstract:

Hieracium pilosella was accidentally introduced to New Zealand about 100 years ago, and since then it has become an aggressive weed, and an unexpected degree of genetic and genome variation has been detected. Data indicate the emergence of sexual hybrids that provide further opportunity for gene flow among taxa in this complex.

Effect of gene flow on spatial genetic structure in the riparian canopy tree Cercidiphyllum japonicum revealed by microsatellite analysis

Article Abstract:

The effect of gene flow on spatial genetic structure in Cercidiphyllum japonicum was explored through genetic analysis at different spatial scales. Both within and among population genetic structure supported the results indicating extensive gene flow in Cercidiphyllum japonicum.
