The Population Structure and Distribution of Sand Dollar across Intertidal Zone at PandanBeach, Lundu and Trombol, Telaga Air Sarawak

A study on the distribution and population structure of sand dollars across intertidal zone was conducted at Pandan Beach, Lundu (January, 2014) and Trombol, Telaga Air (October, 2013), Sarawak. This study aims to determine the distribution and population structure of sand dollars across intertidal...

description A study on the distribution and population structure of sand dollars across intertidal zone was conducted at Pandan Beach, Lundu (January, 2014) and Trombol, Telaga Air (October, 2013), Sarawak. This study aims to determine the distribution and population structure of sand dollars across intertidal zone; and to compare the presence of these organisms in two different areas, with the pore water parameters and sediment type. Sand dollar specimens were collected along line transects within quadrats. Simultaneously, sediment and selected parameter of pore water (pH, salinity, temperature) were recorded. Two species were found at both study areas namely Arachnoides placenta and Echinodiscus tenuissimus. Results indicate that there were significant difference (One Way ANOVA and Linear regression, p < 0.05) of density and test diameter of adult and juvenile sand dollars across intertidal zone at Trombol only. Furthermore at Lundu, significant negative correlation was showed between sediment (silt and clay) and density of juvenile sand dollars. At Trombol, positive significant correlation was showed between salinity and density of juvenile sand dollars. Thus, further study can be carried out to determine why certain parameters influence more on the juvenile rather than the adult sand dollars.
