Relationships between kelp productivity (g FW ind−1 day−1) and mean in situ temperature for Ecklonia radiata from Western Australia. Panel (a) shows the relationship between productivity and temperature for all individuals (n = 375) sampled and reflects kelp productivity likely to be achieved under a traditional restoration scenario where individuals are randomly selected from the population for use in restoration efforts. Panel (b) shows the relationship for the top 10% most productive individuals at each sampling location, which represents a productivity-informed restoration scenario where highly productivity individuals are strategically selected for use in restoration efforts. Panel (c) shows the relationship for individuals sampled at the species warm-range edge (i.e. Jurien Bay) and represents a traditional assisted adaptation scenario given that heritable genetic traits linked to selection for temperature tolerance are known to occur in these individuals. Panel (d) shows the relationship for the top 10% most productive individuals sampled at the warm-range edge, which represents a productivity-informed assisted adaptation scenario where highly productive individuals that also have heritable genetic traits linked to temperature tolerance can be selected for use in assisted adaptation efforts. Dashed lines around model fits represent 95% confidence intervals. Grey data in panels (b), (c) and (d) were excluded when fitting these relationships.
