Physico-chemical Analysis and Morphometric Variability Within and Between Populations of Pitar frizzelli in Panguil Bay, Philippines

Abstract:

The study was conducted to determine variation within and between populations of a marine bivalve, Pitar frizzelli, based on fourteen significant biological characters of the shell by descriptive statistics, analysis of variance (ANOVA) and Tukey’s post hoc test. The results revealed that there is significant difference within and between populations which may be phenotypical plasticity in response to different environmental and/or ecological conditions existing in the three areas. The physico-chemical parameters which included sediment salinity, pH, temperature and type of substrate, showed significant relationship with the morphological characters.
