Data from: Microgeographic variation in early fitness traits of Pinus sylvestris from contrasting soils
<p>Seedling phenotypic data from two Iberian <em>Pinus sylvestris</em><em> </em>provenances from contrasting soils (calcareous vs. siliceous) grown in a 3-year greenhouse experiment on both types of natural local substrate. Each line in the file corresponds to a different seedling.

Within and between population comparisons suggest independently acting selection maintaining parallel clines in Scots pine (Pinus sylvestris)
<p>Parallel clines in traits related to adaptation in a species can be due to independent selection on a pair of traits, or due to selection in one trait resulting in a parallel cline in a correlated trait. To distinguish between the mechanisms giving rise to parallel adaptive population divergence of multiple traits along an environmental gradient we need to study variation, correlations, and selective forces within individual populations along the gradient. In many tree species, budset timing forms a latitudinal cline, and parallel clinal variation is also found in other seedling traits, such as first year height and fall frost injury. In this study, we set up a common garden experiment with open pollinated progeny from natural populations of Scots pine (<em>Pinus sylvestris</em>), with one large sample from single population (500 families) and smaller samples from across a latitudinal gradient. Budset timing, first year height and induced fall frost injury were first measured in a greenhouse. The seedlings were then planted in the field, where survival and height were measured at the age of nine years as fitness proxies. We compared between and within population variation and genetic correlations of these three seedling traits, and estimated selection gradients at the family level in our main population, taking into account the potential effects of seed weight. Between population genetic correlations between seedling traits were high (0.76-0.95). Within population genetic correlations in the main population were lower (0.14-0.35), as in other populations (0.10-0.39). Within population, extensive adaptive variation persists in the seedling traits, in line with rather weak selection gradients, yet maintaining the clines. Although our sampling does not cover the whole cline equally, the results suggest that the individual clines in these traits are maintained by largely independently acting selection, which results in fewer constraints in adaptation under changing climate.</p>

Changes in the intensity of heartwood formation in Scots pine (Pinus sylvestris L.) ontogenesis
<p>An essential stage in woody plant ontogeny (heartwood (HW) formation) determines tree resistance to weather conditions, wood quality (moisture, colour, resistance to biodegradation), and regulates the proportion of functionally active sapwood (SW) in the total trunk biomass. In this study, the patterns of HW formation depending on tree age and cambial age within the same tree were studied in the North-West of Russia in Scots pine in a lingonberry pine forest. It is shown that HW either repeats the trunk profile or shows a maximum proportion on average at the height of 1.5 m. Models using the square root transformation and logarithm transformation have been proposed to predict the number of annual rings in HW depending on the cambial age. Multiple regression is proposed to predict the radial width in HW. Validation of the developed models on random trees gave a good result. HW formation begins at the age of 17–18 years and continues at the rate of 0.3 rings per year for 20–30-year-old trees, 0.4–0.5 rings per year for 70–80-year-old trees, and about 0.7 rings per year for 180-year-old trees. The lifespan of xylem parenchyma cells ranged from 10–15 years in 20-year-old trees to 70 years in 180-year-old trees. At the age of the previous felling (70–80 years) the HW area in the trunk biomass is about 20%, and in 180-year-old pine forests, it increases to 50%. These data can be used to assess the role of old-growth forests in carbon sequestration.</p>
Data from: Location, but not defensive genotype, determines ectomycorrhizal community composition in Scots pine (Pinus sylvestris L.) seedlings
<p class="western"><span><span><span>1. For successful colonisation of host roots, ectomycorrhizal (EM) fungi must overcome host defence systems, and <span>defensive phenotypes have previously been shown to affect the community composition of EM fungi associated with hosts</span>. Secondary metabolites, such as terpenes, form a core part of these defence systems, but it is not yet understood whether variation in these constitutive defences can result in variation in colonisation of hosts by specific fungal species.</span></span></span></p> <p class="western"><span>2. We planted seedlings from twelve maternal families of Scots pine (<i>Pinus sylvestris</i>) of known terpene genotype reciprocally in the field in each of six sites. After three months we characterised the mycorrhizal fungal community of each seedling using a combination of morphological categorisation and molecular barcoding, and assessed the terpene chemodiversity for a subset of the seedlings. We examined whether parental genotype or terpene chemodiversity affected the diversity or composition of a seedling's mycorrhizal community.</span></p> <p class="western"><span><span><span><span>3. While we found that terpene chemodiversity was highly heritable, w</span>e found no evidence that parental defensive genotypeor defensive phenoytpeaffected associations with EM fungi. Instead, we found that the location of seedlings, both <span>within and between sites</span>, was the only determinant of the diversity and makeup of EM communities.</span></span></span></p> <p class="western"><span><span><span>4. These results suggest that <span>while EM community composition varies within Scotland at both large and small scales</span>, variation in constitutive defensive compounds does not determine the EM communities of closely cohabiting pine seedlings. Patchy distributions of EM fungi at small scales may render any genetic variation in associations with different species unrealisable in field conditions. <span>The case for selection on traits mediating associations with specific fungal species may thus be overstated, at least in seedlings.</span></span></span></span></p>
