Developmental instability is a simple, inexpensive and sensitive approach for identify and monitoring stressed ecosystem. In this study, a developmental instability approach was applied to identify stressed coastal area in northern Taiwan. A study site is located at Pa-Dor-Tze which is near a landfill site and the other study site is located at Wai-Mo-San which is north of the Keelung port. A reference site is located a Red-Ben which is 4 km south of PA-Dor-Tze. A marine crab, Grapsus albolineatus, which commonly present in all sites was chosen for measuring fluctuating asymmetry as indicators of developmental instability. Salinity, dissolved oxygen, conductivity, COD, pH and temperature were measured in all sites and there were no significant difference in seawater among three sites. Limb segment lengths, carapace lengths and carapace widths were measured twice for each crab. Then, the difference between right and left limb segment lengths among three sites were compared by using Krustal-Wallis ANOVA test and Tukey post hoc test . Results of this study indicated that there were significant differences in the body sizes of Grapsus albolineatus collected from three sites. The level of fluctuating asymmetry in second and third walking legs were significant different between Pa-Dor-Tze and Wai-Mo-San site. Overall, there is an increase of fluctuating asymmetry for leg segments of crabs from Pa-Dor-Tze site compared to the other two sites. |
