Article Synopsis
- Researchers investigated how to revive dormant dinoflagellate cysts buried for about 150 years using melatonin and gibberellic acid, substances commonly used to kickstart seed growth.
- The study successfully revived 11 dinoflagellate taxa from century-old sediments, extending the known viability of these cysts beyond 100 years.
- It was found that while lower concentrations of the biostimulants promoted germination, higher doses inhibited it, indicating that careful dosing is crucial for effective revival of these ancient organisms.
Kelp ecosystems form widespread underwater forests playing a major role in structuring the biodiversity at a regional scale. Some seaweeds such as Laminaria digitata are also economically important, being exploited for their alginate and iodine content. Although some studies have shown that kelp ecosystems are regressing and that multiple causes are likely to be at the origin of the disappearance of certain populations, the extent to which global climate change may play a role remains speculative.
