Marine species with ranges that span the Indo-Australian Archipelago (IAA) exhibit a range of phylogeographical patterns, most of which are interpreted in the context of vicariance between Indian and Pacific Ocean populations during Pliocene and Pleistocene low sea-level stands. However, patterns often vary among ecologically similar taxa, sometimes even within genera. This study compares phylo...

The patchy distribution of rocky intertidal communities in the tropical eastern PaciWc (TEP) may impose severe constraints on the genetic connectivity among populations of marine invertebrates associated with this habitat. In this study, we analyzed a portion of the mitochondrial cytochrome c oxidase subunit I (COI) gene in two sympatric species of marine snails, Nerita scabricosta and Nerita f...

Recent research has identified marine molluscs as an excellent source of omega-3 long-chain polyunsaturated fatty acids (lcPUFAs), based on their potential for endogenous synthesis of lcPUFAs. In this study we generated a representative list of fatty acyl desaturase (Fad) and elongation of very long-chain fatty acid (Elovl) genes from major orders of Phylum Mollusca, through the interrogation o...

Climatic cycles have frequently been hypothesised to influence the phylogeography of temperate marine organisms through such factors as hydrological changes and landbridge formation at glacial maxima. However, it is rarely considered whether observed phylogeographic patterns are predominantly influenced by most recent cycle or those that preceded it. Whether high genetic divergences within inte...

This study aimed to examine the usefulness of locally found gastropod snail, Nerita lineata as suitable biomonitor for metal pollution. The accumulation and elimination of chromium (Cr) and lead (Pb) was examined by exposing N. Lineata to different concentrations of Pb (1-4ppm) and Cr (12-15 ppm) under controlled laboratory conditions. The experiments were allowed for four days of accumulation ...
