Lack of Long-term Acclimation in Antarctic Encrusting Species Suggests Vulnerability to Warming
Marine encrusting communities play vital roles in benthic ecosystems and have major economic implications with regards to biofouling. However, their ability to persist under projected warming scenarios remains poorly understood and is difficult to study under realistic conditions. Here, using heated...
