We inferred variation in autumn phenology and dormancy progression from freeze hardiness tests conducted on >5000 seedlings, of which >900 seedlings from 24 populations were genotyped using genotyping-by-sequencing (GBS). Our main goal was to evaluate adaptive responses in Scots pine at phenotype and genotype levels. Evaluation of cold hardiness along environmental and geographical gradients would contribute to an understanding of the performance of these gradients for predicting freeze damage levels. The genotype data allow evaluation of genetic variance across landscapes and thus shed light on the degree of genetic-environmental association and the recolonization history of Scots pine in Scandinavia.

The sites were located in the south (S), northeast (NE) and northwest (NW) parts of Sweden. At the studies sites, forest had been harvested and mechanical soil preparation had been performed the same year as planting. Seedlings of Scots pine, Norway spruce and silver birch were planted in June 2019 at the NW site and June 2020 at the NE and S sites. At each site seedlings of the different species were planted in both in one-species and mixed plots, one plot treated with arginine-phosphate and on with untreated seedlings for each species composition. Survival- and growth inventory of was performed in august-september 2020 at the NW site and in 2021 at the NE and S sites, following two growing seasons in field. The data consists of survival, height and stem base diameter measurements from the inventories. The variables are described in detail in the documentation file. Three data files are included, one for each site which were all analyzed separately: a. effects_APtreatment_data_S_second_season.csv (1132 rows × 11 columns) b. effects_APtreatment_data_NE_second_season.csv (1987 rows × 10 columns) c. effects_APtreatment_data_NW_second_season.csv (1093 rows × 9 columns) Also, the commented R script Code_manuscript_SND.R is included for reproduction purposes. It should be unpacked in the same directory as the data files. The PDF files in output_plots.zip are the plots generated from the script, and Code_manuscript_SND.log.txt contains log generated by the shell command: Rscript Code_manuscript_SND.R > Code_manuscript_SND.log.txt Tue, 18 Oct 2022 09:18:39 GMT https://researchdata.se/en/catalogue/dataset/2022-163-1 https://researchdata.se/en/catalogue/dataset/2022-163-1 Swedish University of Agricultural Sciences Bodil Häggström In this study, we sampled 54 Scots pine populations from the Norwegian coast over the Arctic Circle to western Russia covering 47.3 longitudes or more than 1/8th of the earth’s circumference, which represents the most comprehensive coverage of Northern Europe to date.

The genotype data allow evaluation of genetic variance across landscapes and thus shed light on the degree of genetic-environmental association and the recolonization history of Scots pine in Scandinavia. Environmental variables for each population was extracted based on their latitude and longitude at origin from 68 different high resolution environmental grids. These variables were then used for phenotype- and genotype-environment association analyses. A description of all variables can be found in Table S2 in “Document S1. Supplemental methods, Supplemental Figures 1–4, and Supplemental Tables 1–6.”, available from doi.org/10.1016/j.xplc.2020.100139 Fri, 29 Jan 2021 07:50:20 GMT https://researchdata.se/en/catalogue/dataset/2020-208-4 https://researchdata.se/en/catalogue/dataset/2020-208-4 Umeå University David Hall The aim of the data collection was to examine differences in biodiversity between two different age classes of production forest stands. Surveys were conducted between 2016-2017 in forty managed production forest stands in southern Sweden. Stands are dominated by two different tree species: Scots pine and Norway spruce and belong to two different age classes: 55 (+/- 5) and 80 (+/- 5) year old. In total ten stands of each category (tree species and age class) were surveyed. There are four separate data sets for species: birds, bryophytes, epiphytic lichens and vascular plants. Species data consists of presence/absence data for the different stands. There is also one data set with stand structures. The five different data sets can be connected using a stand ID that can be found in all of the files. Data consists of information about 26 bird species, 84 bryophyte species, 57 lichen species and 102 vascular plant species. Files consist of 5 separate matrices with 40 rows that are stored in .csv format (comma delimited). Data set 'bird.csv' has 40 rows and 29 columns. Data set 'bryophyte.csv' has 40 rows and 87 columns. Data set 'epilichen.csv' has 40 rows and 60 columns. Data set 'vascularpl.csv' has 40 rows and 105 columns. Data set 'stand_structures.csv' has 40 rows and 7 columns. All data sets have a column "stand", which consist of stand IDs which can be used to connect the different data sets with each other. Information about tree species and stand age class is also provided in the data. For bird species common English names are used. Scientific names are used for vascular plants (Dyntaxa 2019), bryophytes (Hallingbäck 2006) och lichens (Santesson's Checklist of Fennoscandian Lichen-forming and Lichenicolous Fungi 2020). Data was collected during summer of 2016 (birds, bryophytes, vascular plants and forest structure data) and during summer of 2017 (lichen data and forest structure data). Data consist of information from fourty stands. In each stand, 10 plots of 100m2 were used for inventoring bryophytes and vascular plants and 10 trees were surveyed for epiphytic lichens (including branches, up to two metres). Birds were surveyed in four plots per stand within a radius of 40 meters. In the data sets, absence-presence data for the whole stand is shown (i.e. when pooling all plots/trees together). Forest structures were measured within a radius of 10-15 meters in 10 plots per stand, except for dead wood, which was measured in 100 m2 plots. The data set 'stand_structures' shows hectare values based on the average from the plots. Column name explaination: 'stand' = stand-ID, 'tree' = tree species, 'age' = stand age, 'basal_area' = basal area, 'stem_density' = stem densities (stems > 4 cm diameter) and 'wood' = dead wood in m3 (snags, lying wood). The column 'canopy_cover' shows the average canopy cover calculated from 10 hemispherical photos per stand. Stands were selected based on site index (SI 24-29 for Norway spruce) from forest owner management plans. Only stands on till soil with rhyolite or granite bedrock were selected for the study.

Plant communities were surveyed in severely burnt even-aged pine stands that varied in time since clearcutting (0-123 years) before the wildfire occurred. Data includes at the plot-level (50x50cm quadrats): vascular and moss species frequency, total cover, dead wood, and canopy openness. At the stand-level: means for all species, community weighted trait means (trait data from databases), and distance to the fire perimeter. Two files are archived. (1) post_fire_vegetation_TSC_plotlevel_data.csv contains all raw data from each surveyed vegetation plot, (2) post_fire_vegetation_TSC_standlevel_trait_sp_data.csv contains averaged species abundance data and community weighted trait means at the stand level.

The study include 11 trial locations between latitudes 61.1 and 67.1 in the boreal forest of northern Sweden where forest had been harvested and mechanical soil preparation had been performed in 2017 either by mounding or disc-trenching. Scots pine seedlings were planted in May and June 2018. At each site seedlings were planted in three different planting positions, including seedlings treated with arginine-phosphate and untreated seedlings for each planting position. Survival- and growth inventory was performed in August and September 2019 following two growing seasons. The data consists of survival and leader shoot length measurements of Scots pine (Pinus sylvestris) from inventory after two seasons in field at 11 sites across middle and north Sweden as well as site location coordinates, date of planting and inventory along with site environment variables. The variables are described in detail in the documentation file. Data from SMHI has been used, see documentation file. Two data files are included: a. effects_position_APtreatment_data_leader_length.csv b. effects_position_APtreatment_data_survival.csv Field inventory was performed in the end of the second growing season during August-September 2019. All seedlings that had any green needles were registered as living, seedlings with no green needles and missing seedlings were registered as dead. Leader shoot length was measured from the base of the top branches to the top of the terminal bud. Every second alive and undamaged seedling was measured with random start at first or second seedling for each row. At sites where many seedlings were damaged or dead in any of the planting position-and treatment combinations, all remaining undamaged seedlings were measured from that combination.
