Sampling sites are located in the alvar grasslands of Öland, Sweden, from south to north: Albrunna (AB) 56° 19′ N/16° 25′ E, Penåsa (PE) 56° 26′ N/16° 27′ E, Gösslunda (GL) 56° 29′ N/16° 30′ E, Bårby alvar (BY) 56° 31′ N/16° 29′ E and Torrör (TR) 56° 34′ N/16° 34′ E. Microhabitat categories are 1 (low pH, moist), 2 (low pH, dry), 6 (high pH, dry) and 7 (high pH, moist). PGIC electromorph phenotypes were scored as in Prentice et al. [17], [18].
