| Summary: | A study on the taxonomy and some ecological aspects of
meiobenthic harpacticoid copepods found in coastal water of Peninsular
Malaysia was conducted from June 1996 to August 1999. The taxonomic
study was carried out using specimens collected from Langkawi Island,
Pangkor Island, Port Dickson, Tanjung Balau, Tanjung Piai and Redang
Island. A total of 40 species, representing 29 genera from 16 families of
harpacticoid copepods were identified. All the 40 species were unrecorded
species in Malaysian coast. For all species, description, illustration and
taxonomic notes were give The study on some ecological aspects of meiobenthic harpacticoid
copepods was carried out along Port Dickson coast. Samples were obtained
from the established transects perpendicular to the sea using a transparent
hand corer with the inner diameter of3.57 cm.
Harpacticoid copepods were the second dominant group of
meiobenthos found in the studied areas. They contributed between 15% to
60% to total meiobenthos found in the sediment. The density and diversity
distribution of meiobenthic harpacticoid copepods along the shore was
correlated significantly (p<0.05) with certain environmental factors,
namely salinity, dissolved oxygen, percentage of silt, clay and sand, water
content, ground water level, depth of brown layer and sorting type of
sediment. The vertical and horizontal zonation was correlated with the
concentration of chlorophyll a in the sediment. The horizontal zonation
was also correlated with the percentage of clay. The different set of
environmental factors that found to correlate with the meiobenthic
harpacticoid copepod distribution in the different studied areas indicated
that different beaches might have their own environmental factors that
governed the distribution. |
