Marine biologist Dimitri Deheyn recently made an interesting discovery at the Scripps Institution of Oceanography. He found that a protein in intertidal anemones not only boosts their fluorescent output but also provides them with an antioxidant property. This unique protein, called AnthoYFP, allows these anemones to thrive in their ever-changing environment between high and low tide.
Anemones are incredibly resilient creatures that have evolved specialized adaptations to survive in the intertidal zone. Scientists believe that this newly identified protein could be crucial for their survival in the face of increasing stressors due to climate change. By enhancing their ability to handle stress, these anemones have a better chance of passing on their genes to the next generation.
The study, led by biologist Nathaniel Clarke and marine biologist Dimitri Deheyn, focused on three species of anemones along the California coast. They discovered that the AnthoYFP protein not only makes the anemones fluoresce a brilliant green under UV light but also provides them with a unique color morph that is visible under white light. This protein’s dual function of enhancing fluorescence and acting as an antioxidant is a groundbreaking finding in the field of marine biology.
Beyond the intertidal zone, researchers believe that this protein could have broader applications in helping other invertebrates cope with cellular stress. By genetically engineering this protein into other cnidarian species like corals, scientists hope to increase the resilience of these organisms in the face of climate-induced challenges such as rising temperatures, severe storms, and ocean acidity.
The implications of this discovery are significant, especially as coastal ecosystems continue to change due to climate change. Anemones with the AnthoYFP protein could be better equipped to handle incremental stressors like extreme waves, heat, and rising sea levels. This protein could play a crucial role in ensuring the survival of these creatures in the face of environmental challenges.
Citizen scientists like Jami Feldman and Laura Simonato are actively contributing to the study of intertidal ecosystems by documenting species like the sunburst anemone. By sharing their observations on platforms like iNaturalist and social media, these enthusiasts are helping researchers understand habitat shifts and species range expansions that may be influenced by climate change.
As the climate continues to change, the role of citizen scientists in monitoring and documenting intertidal species becomes increasingly important. By raising awareness and encouraging more people to explore and appreciate these ecosystems, individuals like Feldman and Simonato hope to create a brighter and more resilient future for marine life.
