Coastal Macroinvertebrate Study in Penang Island, Malaysia
No full textLand reclamation in Penang began two decades ago and is still rampant with large reclamation projects planned to be executed in the near future. The present study provides the first information on effects of land reclamation in Penang towards the coastal macroinvertebrates. This study assessed the abundance, diversity, and evenness of coastal invertebrates assumed to be the foremost affected when land is reclaimed. Three kinds of areas were focused on: reclaimed, unclaimed (adjacent to reclaimed), and undisturbed. A total of 53 species of macroinvertebrates from 10 classes (Gastropoda, Bivalvia, Polychaeta, Malacostraca, Maxillopoda, Echinoidea, Polyplacophora, Branchiopoda, Scaphopoda, and Holothuroidea) were sampled. Reclaimed areas were moderately rich in species averaging 11 species compared to 7 species in adjacent and 14 in undisturbed areas. Species richness was the highest in Teluk Aling (an undisturbed area) with 22 species, and was the lowest in Gurney Drive (an adjacent area) with 2 species. The average species diversity and evenness on reclaimed land was the lowest with values of 1.9974 and 0.5787, respectively. The diversity was higher by 5.07% in adjacent areas and by 22.92% in undisturbed areas compared to reclaimed areas. Species evenness was 29.75% higher in unreclaimed areas and 17.87% higher in undisturbed areas compared to reclaimed areas. Land reclamation reduces species diversity and evenness, and to a lesser extent, species richness
An optimizing delivery system for object-oriented software
No full textAn open-ended and flexible object-oriented language ideally requires its compiler to optimize code at the time of building complete application systems. Optimum code can be judged in terms of its size, which should be compact, and speed of execution, which should be fast. In addition, the turn-around time for recompilation should be as short as possible. Four strategies, based on graph analysis, have been developed which allow these objectives to be attained in a more consistent manner than with current compilers. The findings are being incorporated in BRUNEL, a new object-oriented language and programming environment, which aims to provide a higher degree of support for abstract design, while generating optimal code for applications. -from Author
The Diversity and Abundance of the Sea Stars (Echinodermata: Asteroidea)from Coral Reefs of the Central South China Sea
No full textThis research was conducted to determine the abundance and diversity status of the sea stars from the central South China Sea. An account is given of the species collected during The Research on the Seas and Islands of Malaysia (ROSES) Expedition 2004 from Archipelago of Beting Patinggi Ali to Pulau Layang-Layang, South China Sea. Fifteen reefs were surveyed in Malaysian waters. Surveys for sea star abundance and diversity were done using SCUBA diving and reef walks at low tide. High abundance and species richness was observed. In total, 6 families, 12 genera and 20 species of sea stars were recorded at the study sites. The most dominant family was Ophidiasteridae (12 species) and the most common genus was Linckia spp. (four species). Terumbu Siput (Erica Reef) exhibited the highest diversity of sea stars amongst all the reefs surveyed in this expedition. Ten colour patterns and variations of Culcita novaeguineae were observed and specific to each sampling location. Entire sea star species observed in this study was first time recorded in Central South China Sea. Most of the species (18 species) observed during this expedition have been recorded elsewhere in the Indo-Pacific, an indication of the successful larval dispersal along the waters of the South China Sea meanwhile two species are new in South China Sea records, namely Fromia sp. and Leiaster sp
