    FORAMINIFERAL DISTRIBUTION AND ASSOCIATION PATTERNS IN THE MANGROVE SEDIMENTS OF KAPAR AND MATANG, WEST PENINSULAR MALAYSIA
    (Journal of Sustainability Science and Management, 2014) BEHARA SATYANARAYANA; MOHD-LOKMAN HUSAIN; RAZARUDIN IBRAHIM; SULONG IBRAHIM; FARID DAHDOUH-GUEBAS
    Twenty-eight foraminiferal species (15 families and 24 genera) were identifed from the mangrove surface sediment samples at Kapar and Matang on the West coast of Peninsular Malaysia. The calcareous forms, particularly Ammonia beccarii and Buccella frigida, were found to be the characteristic of Kapar sediments, whereas agglutinated species like Arenoparrella mexicana and Haplophragmoides wilberti dominated the Matang environment. Based on faunal abundance (roottransformed data), three species’ groupings were distinguished from the Kapar and Matang samples. Group-1 (with two sub-groups) dominated by Ammotium fragile, A. salsum, Miliammina fusca and Reophax moniliformis was found to be representative of Kapar, whereas Group-2 dominated by A. mexicana and H. wilberti was found to be representative of Matang. Group-3 was eventually separated from the Kapar (i.e. Group-1) due to the presence of A. beccarii and B. frigida which prefer nearshore/seaward areas with high salinity. Canonical Correspondence Analysis (CCA) indicated that (relatively) high salinity (30‰), pH (8), and sandy texture (70%) with low total organic carbon (TOC) (10%), characteristic of Kapar sediments, supported the distribution of A. fragile, A. salsum, M. fusca, R. moniliformis, A. beccarii and B. frigida, while a high composition of clay (31%) and TOC (30%) supported A. mexicana and H. wilberti (Matang) species. Overall, the distribution of foraminiferal species was locally governed by two different environmental settings prevailing at Kapar and Matang.

    TYPE AND ABUNDANCE OF MARINE DEBRIS AT SELECTED PUBLIC BEACHES IN SARAWAK, EAST MALAYSIA, DURING THE NORTHEAST MONSOON
    (Journal of Sustainability Science and Management, 2014) JULYUS-MELVIN MOBILIK; TECK-YEE LING; MOHD-LOKMAN HUSAIN; RUHANA HASSAN
    Different forms of debris pollute the marine environment. Due to lack of knowledge and awareness among the public on the negative impacts of marine debris, coastal areas such as beaches have been polluted and contaminated with waste. Existing knowledge on marine debris in Malaysia, especially in the state of Sarawak are limited. Therefore, a study was conducted at four beaches in Sarawak to document the types and abundance of marine debris. Marine debris items were collected and categorized during beach surveys at Pandan (Lundu), Pasir Pandak (Santubong), Temasyah (Bintulu) and Tg. Lobang (Miri) in October 2012. Plastic category was the most numerous (90.70%), followed by wood, rubber, glass, metal and cloth contributing 3.53%, 2.20%, 1.78%, 1.58% and 0.21%, respectively. Pasir Pandak beach received the highest quantities of debris (1,120 items/km or 44.1 kg/km). For sources of debris, 23.99% items collected were objects that were directly associated with marine sources. Items associated with terrestrial and common sources were 11.67% and 64.34% respectively. Out of the 21 objects identifed as marine source debris, 86.91% comprised of ropes, oil bottles, packaging and cigarette lighters which were present in all study sites. Five highest number of items found in all the study sites for the terrestrial source debris were wrappers, shopping bags, cardboard cartons, aluminium cans and cloths which contributed a total of 97.98%. Clear and coloured plastic bottles represented 46.15% of the total objects in the common source debris. A total of 730 item/km of debris at 42 kg/km was collected from this study. The high number of plastic-based items contributed from the terrestrial and common sources indicates that continued efforts need to be made to reduce marine debris on those beaches.
