Write 9 pages thesis on the topic effect of ocean acidification upon ability to genetically adapt in nereis species. Polychaete worms have the ability to modify and alter their metabolic rates so as to enable them to cope up with waters in high carbon dioxide (CO2) which is poisonous and able to kill other closely-related species. The study explores the robustness of some marine species such as polychaete worms as well as their resilience of marine biodiversity in case atmospheric carbon dioxide continues to cause much ocean acidification. The following sensitive and tolerant species of polychaete worms that live underwater in places of elevated carbon dioxide (pCO2) were studied: Nereis succinea, Nereis diversicolor, Nereis virens, Platyneire sdemerilli and Nereis sonata. These worms were collected from different areas. Some samples were from the Ischia region, a place with low pH value due to CO2 vents. These individuals were exposed to low pH value environments for a short time and long-term durations. The control group was set in a normal pH environment. The responses of the worms were monitored and it was found out that the worms were physiologically and genetically adapted to living in extremely acidic conditions whereas others were able to adjust their metabolic rates for survival.
