Abstract
There is an urgent need to devise a
comprehensive and ecologically relevant in
situ biomonitoring method for assessing
environmental health. 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
presented 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 a one-way
ANOVA test and the Tukey multiple test.
The results of this project showed that the
levels of fluctuating asymmetry in different
leg segments of Grapsus albolineatus at Pa-
Dor-Tze were significant higher than those of
Grapsus albolineatus at Wai-Mo-San and
Red-Ben between 1998 and 1999. However,
the level of fluctuating asymmetry in
different leg segments of Grapsus
albolineatus at Pa-Dor-Tze were reduced and
became the same levels of those of Grapsus
albolineatus at Wai-Mo-San and Red-Ben in
2000
