Developmental stability via Fluctuating Asymmetry in the shell shape of Gafrarium tumidum (Tumid Venus Clam) found in Panguil bay
Abstract
Fluctuating asymmetry is the extent at which an organism departs from the ideal symmetry. It increases as the environmental stress increases and thus referred to as a tool for measuring developmental stability and environment quality. The purpose of the study is to demonstrate the use of fluctuating asymmetry as a tool for monitoring developmental stability of Gafrarium tumidum (Tumid venus clam) and environment. This study determined the developmental stability of G. tumidum via fluctuating asymmetry collected from two coastal areas around Panguil Bay. Thirteen anatomical landmarks were used and were subjected to Procrustes superimposition and Principal Component Analysis (PCA) using “Symmetry and Asymmetry in Geometric Data” (SAGE) program. Procrustes ANOVA result showed no significant evidence of fluctuating asymmetry on both populations. But yield significant result for directional asymmetry, ‘sides’ interaction which suggests that observed variation in populations examined is of genetic origin and not due to environmental stress. It also suggests that populations in the area have the ability to buffer stress. Thus, G. tumidum is relatively developmentally stable and the environment that it inhabits is fairly tolerable. Hence, relatively fit for cultivation to maximize yield for food production.
