Figures & data
Fig. 1. Sea surface temperature and number of recruits, reproductive and non reproductive individuals per square metre for S. polyschides populations from (A) North Portugal and (B) Brittany, France. * indicates a lack of data for that month, due to storms precluding fieldwork.
Fig. 2. Growth rate through time for sporophytes from Portugal (left) and France (right) at the different culture temperatures. There is no 20°C point at day 18 in the Portuguese set due to 100% mortality.
Fig. 3. Number of days needed, from the time of induced zoospore release, for a sporophyte big enough to be observed in the field (5 cm) to develop, for the populations from North Portugal (Pt) and Brittany, France (Fr) at the four temperatures where sporophytes were formed. Significant differences were found between all temperatures. No data for the Portuguese set at 20°C are displayed due to 100% mortality.
