Abstract

Over parts of the rocky north shore of Penang Island, West Malaysia, and Pulau Tikus, a small island one mile offshore from Penang, coral communities (Gorgonacea, Alcyonacea, Scleractinia) may be found in the turbid inshore waters. These corals are bathed by the waters of the Muda River system on the mainland and by the waters fluxing through extensive mangal along the mainland and around Penang Island. The diverse components of the coral community are truly intertidal being exposed during spring low tides throughout the year. It appears as though the gorgonians of the coral community are unusual in their diversity and intertidal distributions. So, too, does it appear, are the ovulid gastropods associated with the gorgonians. I will, both orally and visually, described the Penang-Pulau Tikus intertidal coral community, elaborate on the gorgonians and their associated ovulid snails, and discuss the stresses placed upon the complex by man.

Abstract

Biscayne Bay is a shallow subtropical estuary, 225 square miles of water, at the edge of the tropics, located within Dade County, one of the fastest growing counties in the U.S.A. The fragility of this seagrass and mangrove dominated estuary has been demonstrated by repeated destruction of these ecosystems by mans activities, such as dredging, filling, drainage, sewerage, thermal pollution, and others. At the southern end, the U.S. Department of the Interior has recently established the Biscayne Monument, a preserve area where fairly rigit restrictions for mans use of the biota are enforced. At the northern end, intense land development since 1910 along with establishment for artificial islands and causeways, bulkheading, sewerage outfall and other pollutants has altered the ecology greatly. Approximately 1.5 million people inhabit this area. Multiple authorities for regulating use in the bay and its shoreline exist ranging from county to Federal. Many problems of overlapping jurisdiction and enforcement occur. Two symposia to bring together the knowledge of processes occurring m the bay and to delineate a policy for managing the bay were held in March 1976 resulting in the Volume, Biscayne Bay: Past, Present, and Future. Aspects of the ecology of this bay and of the management problems and goals will be discussed.

Abstract

The check-list of the fish collected during the CORINDON expeditions (COR. II: 20 sampling stations in the Makassar Strait; COR. IV: 7 stations in Piru and Ambon Bay in the Moluccas) 2) is composed out of 110 species. Most of them are coming from depths between 250 m and 600 m; a dozen of species were found at less deep stations; two Apodes, of which one is the very rare Promyllantor, were collected at a 1000 m depth.

Abstract

Experiment on Holothuria atra provided evidence that asexual reproduction by fission was possible to be stimulated at laboratory. The success of the experiment was determined based on the high survival of stimulated individuals that grew into intact. After being tightened, induced individuals divided into anterior- and posteriorend individuals. During regenerating into intact individuals, the body weight decreased to relatively minimum weight. Developing of new tentacles in posterior-end individuals and anal aperture in anterior-end individuals required 7-8 weeks after fission. These indicators may lead to anatomical recovery which may be a sign of feeding necessity.

Abstract

Monthly larval release by the coral Pocillopora damicornis at Panjang Island, Central Java was investigated. Corals were collected from windward and leeward and maintained in outdoor, flow-trough system to quantify nightly release of larvae. Larval release of the coral occurs every month throughout the year, and its planulation increased during dry monsoon. Monthly planulation occurs from new moon to full moon and possesses in different pattern between single and paired colonies. Planulation in paired colonies occurred in single peak and more synchronized in each colony however single colonies planulated in double peaks and less synchronized in each colony. This study confirmed that planulation period of P. damicornis at Panjang Island over a range of lunar phases with shorter periods of peak release which predominantly controlling by tidal range rather than lunar cycle.

Abstract

Brantas River basin and Madura Strait in East Java Indonesia, are subject to heavily change in land use and land cover, and Brantas River Basin is a very important densely populated area in East Java, Indonesia for agriculture, industry as well as for settlement. The aim of the research is to elucidate the fate of transformation of bio-elements (organic carbon, Nitrogen (N), Phosphorus (P), and Silicate (Si)) and its seasonal variability. The contrast river discharge combined with tide generates the distinctive mixing zone during rainy and dry season. Dissolved Inorganic Nitrogen (DIN) and Dissolved Inorganic Phosphorus (DIP) concentrations in the river are high and decrease to the very low value seaward. N:P ratio has seasonal variation due to large discrepancy of DIN and DIP supply from land to the sea. Dissolved Inorganic Silicate (DSi) in river and estuaries is extremely higher than the average in the world (> 150 mM). Chlorophyll-a (Chl-a) in dry season in the coastal water is higher than the rainy season. Due to high Total Suspended Matter (TSM), the primary production is limited by the light in the coastal water.

Abstract

Temperature observations across the sill of Ambon Bay in August 1982 and a model suggest that during the upwelling season of the south east monsoon tidal upwelling on the flood tide can suck thermocline water up the outer slope of the sill from a depth of 50 to 80 m. The water enters over the 10 m sill and replaces the bottom water in the inner part of Ambon Bay.

Abstract

Nitzschia navis-varingica is recognized as the major ASP toxin producer other than Pseudo-nitzschia species. Surveys on the distribution and the toxin production of this diatom has been conducted in a few countries in eastern Asia and expanded to Thailand. Eighteen isolates from Thailand showed the positive result for the ASP toxin production is DA and IB, although the ratio of IB was much lower than those of the isolates from southern countries including Okinawa, Japan, the Philippines and Vietnam.

Abstract

Sponges are one of the most diverse benthos in the coral reef ecosystem. They have many morphological characters that are specific to species, and their existence is influenced by environmental conditions. The aims of this study are to observe the relationship between morphological and species diversity of sponges in coral reef ecosystem in the Lembeh Strait and investigate the most influential environmental factor on sponge diversity. The study was carried out between April and May 2013 at nine study sites. The methods used were belt transect and line intersect transect (LIT) installed parallel to the coastline at approximately 5-meter depth. Our study supports a positive correlation between the morphological diversity and species diversity of sponges. Many of the morphological growth types were specific to sites that have particular characteristics. The percentage of the live coral cover is not a critical factor for sponge diversity in the strait. Instead, dead coral with algae as a benthic category has a significant positive correlation with the morphological and species diversity of sponges. Conversely, rubble as a substrate type has a strong tendency to affect sponge diversity negatively. To conclude, it is important to maintain healthy reefs in order to sustain benthic communities that are valuable to ecological functions and societies. Keywords:sponges, diversity, coral reefs, Lembeh Strait

Abstract

The diversity and community structure of macroalgae at Koh Taen, Haad Khanom-Mu Koh Tale Tai, marine National Park, Nakhon Si Thammarat Province, Thailand were investigated from 1st- 5th October 2005 (preliminary survey). Out of a total of 41 species: 15 species each of green and red algae, 9 species of brown algae and 2 species of blue green algae were found. In the area, subsequently four sites were established for monitoring. Quadrat sampling was employed to assess the abundance of macroalgae. In total sixty quadrats were monitored each month from October 2005 to April 2007. We report the variations of diversity and abundance of macroalgae among sites and seasons and speculate about what might cause such variations.
