Research Progress on Ecological Effects and Mechanism of Ocean Acidifi-cation on Algae
Presently,ocean acidification(OA)is escalating at an unprecedented pace,posing a considerable threat to the chemical equilibrium of seawater.This acceleration has the potential to disrupt the marine ecological environ-ment significantly,affecting various organisms.Among these,algae,the primary producers in the ocean,contribute 95％of productivity and play a vital role in material and energy cycling.The increasing acidity in the ocean could alter algae productivity,subsequently impacting material and energy transfer through the marine food web.Such changes may initiate a cascade effect in the food chain,leading to irreversible damage to the entire marine ecosys-tem.Additionally,algae's heightened sensitivity to environmental changes makes them valuable as"indicator or-ganisms"for monitoring water quality.Therefore,assessing the ecological impact of ocean acidification on algae is crucial for ecological research.This review aims to outline the effects of ocean acidification on the physiological and biochemical processes of algae over recent years.This includes aspects such as photosynthesis,inorganic car-bon fixation,growth,calcification,reproduction,as well as metabolic components and microstructure.The review also explores how ocean acidification influences the molecular regulation mechanisms of algae,considering its combined effects with environmental factors and marine pollutants.Furthermore,the article analyzes the limitations of current algae research on ocean acidification and proposes solutions and strategies to address this pressing issue.
