We investigated the gene flow of the common marine diatom, Skeletonema marinoi , in Scandinavian waters and tested the null hypothesis of panmixia. Sediment samples were collected from the Danish Straits, Kattegat and Skagerrak. Individual strains were established from germinated resting stages. A total of 350 individuals were genotyped by eight microsatellite markers. Conventional F- statistics showed significant differentiation between the samples. We therefore investigated whether the genetic structure could be explained using genetic models based on isolation by distance (IBD) or by oceanographic connectivity. Patterns of oceanographic circulation are seasonally dependent and therefore we estimated how well local oceanographic connectivity explains gene flow month by month. We found no significant relationship between genetic differentiation and geographical distance. Instead, the genetic structure of this dominant marine primary producer is best explained by local oceanographic connectivity promoting gene flow in a primarily south to north direction throughout the year. Oceanographic data were consistent with the significant F ST values between several pairs of samples. Because even a small amount of genetic exchange prevents the accumulation of genetic differences in F -statistics, we hypothesize that local retention at each sample site, possibly as resting stages, is an important component in explaining the observed genetic structure.

A study of the genetic structure and differentiation of eight populations of Pinus sylvestris L. on the Russian Plain showed that the populations of PsI and PsII (D=0.066) are located at the smallest genetic distance, and between the populations of PsI and PsIV (D=0.308) at the greatest genetic distance. On the dendrogram, the studied populations formed four clusters: PsI and PsII; PsIII and PsIV; PsV and PsVI; PsVII and PsVIII. Analysis of the genetic structure of eight populations of P. sylvestris showed that the expected proportion of heterozygous genotypes (HT) for the total sample was 0.320, the expected proportion of heterozygous genotypes in a single population for all loci (HS) was 0.170, therefore, the population subdivision (GST) was high and amounted to 0.468. The studied populations are highly differentiated, since the interpopulation component accounts for 46.8% of the genetic diversity. In all studied populations, the indicator h has values less than 0.3. An analysis of the fraction of rare alleles showed that the genetic structure is less balanced in the populations PsIII (h=0.254) and PsIV (h=0.273). The most balanced genetic structure in the populations of PsVII (h=0.112) and PsVIII (h=0.127). Data on the genetic structure and differentiation of the common pine populations should be taken into account when developing recommendations for preserving their gene pools.
