Environmental and genetic data on 1926 Galium verum ramets sampled in 35 landscapes in NW-Europe

This Figshare data-file contains three files which are linked via unique identifiers to reconstruct all the data needed to investigate the impact of green infrastructure on the functional connectivity in the grassland perennial Galium verum in fragmented semi-natural grassland landscapes in 35 landscapes spread across Sweden, Germany and Belgium. RawMicrosatelliteData.txt Genotyped microsatellite data for 9 markers for 1926 sampled individual ramets from the plant species Galium verum, collected across 35 landscapes in Sweden, Germany and Belgium. The dataset is formatted along the Spagedi-software requirements which was used to calculate the genetic diversity metrics. IndividualDescriptor.xlsx Environmental descriptors of 1926 individual ramets of the plant species Galium verum sampled across 35 landscapes in Sweden, Germany and Belgium. Via their unique ID (Ind), they can be linked to their associated genotype and their geographic position as available in RawMicrosatelliteData.txt. The environmental desciptors describe in which country, landscape or element (focal patch [1], stepping stone [4] or linear feature [2 and 3]) the individual was sampled. <br> Landscape_Composition.csv Environmental descriptors including landscape and focal genetic diversity metrics for 35 landscapes across Sweden, Germany and Belgium in which the grassland perennial plant species Galium verum was sampled.<br> Besides the descriptor "Landscape" making it possible to link these descriptors to the individual ramets in RawMicrosatelliteData.txt and IndividualDescriptor.xlsx, environmental descriptors include structural and inferred functional connectivity and various components which make up the green infrastructure, i.e. amount of semi-natural grassland habitat [ha], amount of road infrastructure [m] and the amount of forest or arable cover [ha]. Further landscape information is provided by the descriptors on "Landscape occupancy of Galium verum" and "Restored", informing on the abundance of Galium verum in the landscape surrounding each focal semi-natural grassland patch [0-1] and whether the focal semi-natural grassland patch has been restored [0/1], respectively. <br> Genetic diversity metrics for sampled Galium verum populations include allelic richness, rarified allelic richness and gametic heterozygosity (calculated using Spagedi-software), both for the focal semi-natural grassland central in each landscape as well as for the entire landscape, i.e. the focal patch + its surrounding landscape (r = 1600 m). <br> <br>
