| spatial genetic structure of northern pike (esox lucius) in the baltic sea. | the genetic relationships among 337 northern pike (esox lucius) collected from the coastal zone of the central baltic region and the finnish islands of aland were analysed using five microsatellite loci. spatial structure was delineated using both traditional f-statistics and individually based approaches including spatial autocorrelation analysis. our results indicate that the observed genotypic distribution is incompatible with that of a single, panmictic population. isolation by distance appe ... | 2005 | 15910318 |
