Detailed explanation-1: -The factors influencing kelp forest stability are diverse: kelp harvesting; grazing by fishes, sea urchins, and crustaceans; plant competition; storms; El Niño events; sedimentation; and pollution.
Detailed explanation-2: -Numerous studies have shown that low salinity can initiate stress responses in a range of other kelp species, including impacting photosynthesis (Diehl et al., 2020), growth (Mansilla et al., 2014) and survival (Peteiro and Sánchez, 2012).
Detailed explanation-3: -Temperature at the kelp site ranged from 12.29-21.67°C, while salinity ranged from 32.91-33.65 PSU over this same period.
Detailed explanation-4: -Kelp forest distribution, structure and productivity are influenced by abiotic (e.g., temperature, light, substrata, sedimentation, nutrients, water motion, and salinity) and biotic (e.g., grazing, competition, and disease) factors (Dayton, 1985; Bekkby et al., 2014; Smale, 2020).
