Identification of an altitudinal migration pattern of Abies pinsapo in the Baetic Mountains through the presence of its life stages
<p>This data set is used to explore the altitudinal shift of <em>Abies pinsapo</em> Boiss. in the Baetic System. We analysed the potential distribution of the realised and reproductive niches of <em>A. pinsapo</em> populations in the Ronda Mountains (Southern Spain) by using species distribution models (SDMs) for two life stages within the current populations. The realised and reproductive niches of <em>A. pinsapo</em> are different to one another, which may indicate a displacement in its altitudinal distribution.</p>

Data from: Effects of tree architecture on pollen dispersal and mating patterns in Abies pinsapo Boiss. (Pinaceae)
Plant architecture is crucial to pollination and mating in wind pollinated species. We investigate the effect of crown architecture on pollen dispersal, mating system and offspring quality, combining phenotypic and genotypic analyses in a low-density population of the endangered species Abies pinsapo. A total of 598 embryos from three relative crown height levels (bottom, middle, top) in five mother plants were genotyped using eleven nuclear microsatellite markers (nSSRs). Paternity analysis and mating system models were used to infer mating and pollen dispersal parameters. In addition, seeds were weighed (N = 16,110) and germinated (N = 736), and seedling vigour was measured to assess inbreeding depression. Overall, A. pinsapo shows a fat-tailed dispersal kernel, with an average pollen dispersal distance of 113–227 m, an immigration rate of 0.84–26.92%, and a number of effective pollen donors ranging between 3.5 and 11.9. We found an effect of tree height and relative crown height levels on mating parameters. A higher proportion of seeds with embryo (about 50%) and a higher rate of self-fertilization (about 60%) were found at the bottom level in comparison to the top level. Seed weight and seedling vigour are positively related. Nevertheless, no differences were found in seed weight or in seedling-related variables such as weight and length of aerial and subterranean parts among the different relative crown height levels, suggesting that seeds from the more strongly inbred bottom level are not affected by inbreeding depression. The different relative crown height levels also present a similar effective pollen dispersal distance and number of effective pollen donors, indicating vertical isotropy for outcross pollen. Our results thus suggest that self-pollen may compensate for the shortage of outcross pollen in low density populations.
