Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2015, Vol 7, Issue 1
Abstract
This study was carried out in September, 2013 to August, 2014 in mangrove forest of Likupang waters. It was aimed to know the p[opulation density of Telescopium telescopium, habitat preference and influencing environmental physico-chemical factors. The study used survey method, and the study sites consisted of 2 stations, submerged and dry areas. The former was set 5 points each of which was placed 5 quadrats of 1×1m2 for organism sampling. The latter was put 3 transect lines each of which was placed 5 quadrats of 1×1 m2. Results found that the highest T. telescopium density occurred in the dry area with an average of 41.83m2 and the lowest in the submerged area with an average of 10.58 m2. The habitat preference was higher in the dry area than the submerged area based on the population density. Environmental physico-chemical factors affecting T. telescopium density in both areas were nitrate, phosphate, ammonia, pH, temperature, and salinity.
