Figure 4. Impact of thermal-stress anomalies on Scytothalia transplants experiencing low and high thermal-stress anomalies.

Thallus condition was initially healthy under low stress anomalies (that is, a). Under high stress anomalies thallus deterioration began with brown spotting and other putative disease symptoms (that is, b) before developing into high epibiont cover (c). Note that receptacles remaining in the high-stress anomaly photos are heavily fouled and non-reproductive (c).
