Appendix C.(Table C1). Table showing Tetrix subulata source populations in the southeast of Sweden that were used for constructing experimental founder groups. Table shows coordinates for sites, biotopes, number of propagules from each source, average number of hatched nymphs per clutch in the lab (mean ± SD (N)), and date of release of propagules to enclosures. Ålem is an abandoned farm field nearby a clear-cut. Bredsättra is a small, intensively grazed pasture with a man made pond on the island of Öland in the Baltic Sea. Flyvägen is a burnt clear-cut (spruce). Hägern is a grassland, uncultivated and ungrazed, nearby a burnt clear-cut (spruce and pine). Jordtorpsåsen is an extensively grazed area with alkaline fens on Öland.
