Relationship between algal cover and water chemistry in rockpools

ABSTARCT Intertidal rockpool is one of the harshest environment in marine ecosystem. Most of the organisms living in it has to have adaptions to survive in harsh conditions, especially algal. A research was done to see if abiotic factors such as temperature, dissolved oxygen, temperature and pH value could have a significant correlation with total percentage of algal cover. Initial hypothesis was dissolved oxygen and pH value are correlated to total algal cover. Each pool sample’s water chemistry were measured and tested for 2 day period. The correlation between dissolved oxygen and algal cover is weak, proving that dissolved oxygen is not …show more content…
It is regarded as the most ecological part of the marine system (Olabarria et al, 2012). Rocky shore has three zone; low, mid and high with variety of communities living on each intertidal matrix (Vanschoenwinkel, 2007). High intertidal zone has rockpools and go to several months without being replenished from the seawater (McAllen & Taylor, 2001). Intertidal rockpool have a relative stable environment where that has few changes in terms of physical conditions when the water reaches low tide (Kemp, 2009). Both McAllen & Taylor (2001) and Berschick et al (1987) stated that rockpools undergoes many extreme physic-chemical conditions and few organisms are able to live in rockpools. These abiotic factors have a significant influence in community dynamics and population (Therriault, 2002). Thus, it has large abundance of specialized taxa living in rockpools, such as algae (Murase, …show more content…
