“…Little differentiation between Scottish and mainland European populations of Scots pine at neutral markers (Kinloch et al, 1986;Prus-Glowacki and Stephan, 1994;Provan et al, 1998), but divergence at quantitative traits for characters of adaptive importance (for example, phenology, growth and survival rates, Ennos et al, 1998;Worrell, 1992;Hurme et al, 1997) suggests that selection is driving adaptive differentiation in both geographical regions. As they differ significantly in climatic, edaphic and biotic conditions, it is possible that observed nucleotide and/or haplotype differentiation at dhn2 and dhn7 and some differences in the allele-frequency spectrum at dhy2PP, abaR, a3iP2 and chcs may be due to selection.…”

High genetic diversity at the extreme range edge: nucleotide variation at nuclear loci in Scots pine (Pinus sylvestris L.) in Scotland

Nucleotide polymorphism at 12 nuclear loci was studied in Scots pine populations across an environmental gradient in Scotland, to evaluate the impacts of demographic history and selection on genetic diversity. At eight loci, diversity patterns were compared between Scottish and continental European populations. At these loci, a similar level of diversity (y sil ¼ B0.01) was found in Scottish vs mainland European populations, contrary to expectations for recent colonization, however, less rapid decay of linkage disequilibrium was observed in the former (r ¼ 0.0086 ± 0.0009, r ¼ 0.0245 ± 0.0022, respectively). Scottish populations also showed a deficit of rare nucleotide variants (multi-locus Tajima's D ¼ 0.316 vs D ¼ À0.379) and differed significantly from mainland populations in allelic frequency and/or haplotype structure at several loci. Within Scotland, western populations showed slightly reduced nucleotide diversity (p tot ¼ 0.0068) compared with those from the south and east (0.0079 and 0.0083, respectively) and about three times higher recombination to diversity ratio (r/y ¼ 0.71 vs 0.15 and 0.18, respectively). By comparison with results from coalescent simulations, the observed allelic frequency spectrum in the western populations was compatible with a relatively recent bottleneck (0.00175 Â 4N e generations) that reduced the population to about 2% of the present size. However, heterogeneity in the allelic frequency distribution among geographical regions in Scotland suggests that subsequent admixture of populations with different demographic histories may also have played a role.

“…At the same time different species adapt differently to the same ecological variations. According to previous work, genetic variation among the Scots Pine populations in Scotland is very small [24]. On average, 2% of total isozyme variation in Scotland is accounted for by differences among populations [25].…”

“…on Speyside [38]. These forests are created the most westerly borders of Scots pine in Europe [24] and are considered genetically distinctive from the European population, potentially due to local adaptation subsequent to recolonisation since the last glacial period 10,000 years ago [25]. Generally, researchers have divided Scots pine into two, northern populations and southern populations.…”

Present day populations have been found to contain significant genetic variation [24]. For instance pines in the oceanic climatic regions have thick branches and flexible or bendy trunks.…”

Local adaptation is a key consideration for forestry related activities, particularly when seed is transferred from one seed zone to another for afforestation. Locally adapted trees may show differences in growth when planted in sites other than their origin. Scots pine is one of the most valuable commercial timber trees with higher rate of growth. Although growth differences have been noted in the past, the extent to which Scottish Scots pines are locally adapted at the population level has remained unclear. In this dissertation, some aspects of local adaptation in pine are discussed and previous work is reviewed (essay review) and then (research paper) an experimental trial is presented in which genetic differences among populations and families from the Scottish Scots pine distribution are tested using growth as a measure of performance. Differences are related to climatic variables from the sites of origin of the seed. Finally, the role of provenance/progeny trials or common garden tests in researching local adaptation is also discussed.
