Gametogenesis of gametophytes (Spitsbergen 2011, 2015; 5°C clonal culture, n = 5) was induced at 5°C and sporophytes reared for 6 months. Sporophytes were distributed to three treatment groups. A 17-day heat wave (from 5°C to 20°C and back) followed by a 1-day priming trigger at 21.5°C (HWT); 17 days at 10°C and a 1-day priming trigger (T); a control remaining at 10°C throughout (C). All groups were subjected to a 7-day heat stress treatment at 20°C, 21.5°C, 23°C, and 25°C, where we measured Fv/Fm, percentage of healthy area and survival. All laboratory experiments were carried out at the Alfred Wegener Institute in Bremerhaven, from January to July 2024.
