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.

The study was conducted during two years in two sites. Pollinators (hoverflies and wild bees - including bumblebees and solitary bees) were surveyed with visual observations for 60s twice a week while the plot was in bloom. Leaf-dwelling arthropods (predators, parasitic wasps and herbivores) were collected using vacuum sampling (30s in a 1m by 1m quadrat) of the plots with open flowers. As below-ground organisms, nematodes (predators, herbivores and decomposers) were sampled at the end of each survey season taking a composite sample consisting on three samples per plot (2cm diameter, 15cm depth). All data were summed on the plot level per site and year. For the plant traits, floral area and plant cover surveys were recorded weekly in a 1m by 1m quadrat, within 2 days of sampling pollinators and leaf-dwelling arthropods. The timing of peak bloom for each plant species was defined as the average week number between the two consecutive weeks with the highest number of open floral units. The life cycles of the plant species were classified as annual or perennial (perennial and biennial).

Stenberg Mattias Jonsson Ola Lundin Maria Viketoft The data presents results from a complete randomized block design greenhouse factorial pot experiment with eight treatments and ten replicates per treatment (n = 80) with one potato plant (S. tuberosum, ‘Fontane’) per 5 L pot, at Wageningen University, Netherlands, between February and April 2022. The experiment consisted of three factors, ‘Strip-cropping legacy’ (with two levels), ‘AMF inoculation’ (with two levels) and ‘Herbivore’ (with two levels). The greenhouse was organized in ten spatial blocks and each of the eight treatments was present in each block. In each pot we measured Aphid population growth, AMF root colonization, potato biomass, potato tuber yield, N & P in leaves, and potato plant metabolites using LC-MS untargeted methods.

Riggi Karen Kloth Roland Mumm Ric de Vos To meet climate targets, expanding Populus spp. tree cultivation is proposed as a potential biomass feedstock, especially on agricultural land that does not come into conflict with food production. However, the majority of all biomass potential assessments typically overlook landowner/farmers' perspectives, risking a gap between theoretical potentials and realisation. The dataset was designed to: i) Assess farmers' willingness to cultivate hybrid aspen and poplar ii) Based on (i), estimate the potential for expanding hybrid aspen and poplar tree cultivations over the next decade (2021-2030) iii) Compare the estimate developed in (ii), with previous studies For more details, please refer to the Swedish version.

Here, cleaned and filtered data from the survey is presented. The dataset and the project are thoroughly described in the article "A national-scale dataset of arable plant abundance from citizen science surveys of Swedish field margins" (Note that this article is a data description, and not a study). Collection method: Volunteers from the Swedish Botanical Society surveyed a 100*1 m transect, along the ploughed part of the field margin. All plants in the transect were noted and their abundance estimated. Fields from all of Sweden were surveyed. Data cleaning: The data have been checked and errors corrected in communication with the surveyors. In the cases where uncertainties remained, the sites have been removed in this cleaned and filtered version of the dataset. The excel file consists of two tabs. The first tab provides important information on the proper usage of the data. The second tabs contains the data. The data file consists of 24 columns and 7364 rows. Note that all coordinates are given according to WGS84.

Petter Axelsson Daniel Lussetti F. Merlin Franco Confocal microscopy, electron microscopy and atomic force microscopy images of Arabidopsis thaliana roots, both in wild plants and mutant plants or plants under chemical treatment. The images show cell division phenotypes in pericycle cells, mainly stained with the specific cellulose dye calcofluor white. These results are part of an investigation that seeks to dissect the molecular bases that regulate the regeneration response in Arabidopsis roots after mechanical damage. Mechanical damage by herbivory or abiotic stress is common in nature in plants. Faced with this, plants have developed a rapid regeneration response that allows replacing damaged cells with new cells. In this study we demonstrate that the composition of the cell wall is important to optimize the regeneration response. Particularly, pectin plays a key role in cell-cell adhesion and cell proliferation after wounding. The microscopy images are provided as TIFF files along with metadata tables. The atomic force microscopy data also includes force maps created in JPK NanoWizard.

Plants are treated with biocontrol agents including Pythium oligandrum (a lab strain) and Bacillus amyloliquefaciens (Serenade®). The aim of the study was to investigate how three wild Solanum species are affected by the potato pathogen A. solani and the tested biocontrol organisms. This information is important for our understanding of disease epidemiology and how wild crop relatives can influence intergrated plant management (IPM).

The digitized maps are provided as spatial polygon features (GeoJSON). The original distribution maps are based on an extensive data collection including obtaining spatial information from regional floras and herbarium records, as well as expert opinions. Data was collected by Eric Hultén from around 1935 to 1970 and contain all known records of the species. The collection dates of the herbarium specimens and the dates of the published records will have ranged from the 18th century to 1970. A detailed description of how the original atlas was compiled as well as the method used to georeference and digitize the distribution maps can be found in Arnell et al. (2025a). R scripts and functions to perform the different pats of the digitalization process can be found in the R package 'HultenRangeMaps' (https://github.com/ArnellM/HultenRangeMaps.git). To aid spatial analyses, the package also provides a function to match the digitized distribution maps to the Swedish 10×10 km National grid (or any other grid stored as a polygon spatial feature). Citation: When using the digitized distribution maps , please cite both this dataset (Arnell et al. 2025b) and the accompanying data paper (Arnell et al. 2025a). Resolution and extent: The original maps have an effective resolution of 16×16 km and cover Scandinavia and Finland as well as parts of the Baltic countries, Germany and Russia. Data format: 1909 digitized distribution maps, GeoJSON files Data files: 1909 digitized distribution maps NOTE: The file names of the distribution map files are a combination of the the current accepted scientific name of the species and the original atlas map number (e.g. Lycopodium alpinum_0001.geojson). The current scientific names of the species in the dataset are retrieved from the Swedish Taxonomic Database, Dyntaxa (SLU Artdatabanken 2022). In Dyntaxa, hybrid species are denoted by the symbol ×. To facilitate file handling the symbol × has been replaced by the letter x in the database file names. Included in the database is an R script that allows users to change the letter x in the file names back to the symbol ×. Documentation files: README.txt HultenMetadata.csv - table containing details on the updated scientific nomenclature and manual edits of the digitized distribution maps fixFileNames.R - change the letter x in file names back to the symbol × References: Arnell, M., Auffret, A.

Auffret Kristoffer Hylander The data of epiphytic plants is collected from one central tree located in a 10 x 20 m plot. The tree was climbed and species searched for both along the bole and in the crown. The identity of the central tree could be found in the “event” folder in the excel file. Then the full plot of 10 x 20 m was inventoried for additional species of bryophytes and woody plants of >5 cm and for vascular epiphytes up to around 2 meters on other threes and shrubs. Thus all species of woody species and bryophytes were included but only epiphytic vascular plants. The plots were in three categories: forest, plantation of Eucalyptus or Cupressus and finally homegarden with coffee under shade trees.Kristoffer Hylander collected all specimens. Voucher specimens can be found at the National herbarium in Addis Ababa.
