Fourteen environmental variables were monitored at seven locations along the west coast of Barbados on a weekly basis over a one-year period, 1981 to 1982. The physicochemical and biological data indicate that an environmental gradient exists as a result of increased eutrophication of coastal waters. Growth rates (linear extension) of Montastrea an...

Baseline information on the distribution and abundance of Haliotis kamtschatkana was obtained throughout the Broken Group Islands (BGI) in shallow- (2-5 m) and deep-water (6-9 m) habitats. The study demonstrates that abundance of northern (pinto) abalone varied spatially throughout the area and with depth. The shallow habitats in the study area sup...

Seven fringing reef complexes were chosen along the leeward coast (west) of Barbados to study the effects of eutrophication processes upon the scleractinian coral assemblages. The structure of scleractinian coral communities was studied along an eutrophication gradient with a quantitative sampling method (line transect) in terms of species composit...

St. Martin’s Island is a small sedimentary island situated at the southernmost part of Bangladesh (20°37.6′ N and 92°19.3′ E). The island is surrounded by rocky reefs composed of Neogene bedrock consisting of moderately hard and soft sandstones and conglomerates belonging to the Tipam Sandstone (Islam in Bangladesh J Univ Sheffield Geol Soc 7:269–2...

Compared to the catastrophic impacts of various environmental disturbances and the subsequent recovery of scleractinian coral communities from these events, little is known about the early successional dynamics of coral communities following major volcanic eruptions. The 1988 volcanic eruption of Gunung Api, Banda Islands, Indonesia, provided a uni...
Article
St. Martin's Island (Bangladesh), a biodiversity hotspot in the northeastern Bay of Bengal, continues to be misunderstood by many scientists. There seems to be continued confusion surrounding the geologic history of St. Martin's Island and its intertidal and subtidal geomorphology. St. Martin's Island is a sedimentary continental island surrounded...

Thalassodendron ciliatum, Bangai archipelago, Indonesia This video taken in 1994 documents extensive beds of Thalassodendron ciliatum in the Bangai archipelago, Indonesia. Its thick rhizome allows this species of seagrass to colonize high energy environments on many high energy coral reefs. Extensive Thalassodendron beds form hotspots of productio...

In our 1994 Tropical Biodiversity paper we were the first to document and report that unlike the jellyfish- eating sea anemone (Entacmaea medusivora) in Palau that feeds on one species of jellyfish (Mastigias papua), the sea anemone found in Kakaban lagoon is not only much larger but that it also feeds on 2 other scyphozoans, namely Cassiopea ornat...

The geologic history of Pulau Kakaban, an uplifted atoll, was first described by the Dutch geologist P.H. Kuenen in 1933 based on his visit to the island during the Dutch-organized 1929-1930 Snellius-I Expedition in eastern Indonesia. We were fortunate to get the opportunity to be the first to study the aquatic ecology of the lagoon in 1993. Durin...

The Indonesian Archipelago is one of the richest marine biodiversity areas in the world. While the total biodiversity of any particular area is a function of a complex set of physical, chemical and biological interactions, as well as geological history, it will be useful here to discuss biodiversity at two levels, namely at the ecosystem level and...

Indonesia with a population of over 182 million people is the world's largest archipelagic state (KLH 1992). With over 17,500 islands (only 6,000 inhabited) and one of the longest coastlines in the world, Indonesia has jurisdiction over 5.8 million km2 of tropical seas within its Exclusive Economic Zone (Polunin 1983; KLH 1992; Sloan and Sugandhy 1...

Seagrasses have a wide distribution throughout the world's oceans, being absent only from the polar seas, although the genera Phyllospadix and Zostera are present as far north as the Bering Sea and as far south as the Tasman Sea. From the cold subpolar regions to the equator, seagrasses inhabit a variety of shallow-water coastal habitats where they...

The Indonesian Archipelago plays a key role in global biogeochemical cycles, and forms a barrier as well as a passage for pelagic organisms between the Pacific and Indian oceans (Brinton 1979; Schalk 1987). In addition to their significance in global ocean productivity, the archipelagic seas contain important biogeographical zones that are still po...

Guilcher (1988) used the term "bank reefs" to classify a number of reef types within a single group, of which the patch reefs were considered to be the smallest. We take a slightly different approach, and follow the classification system proposed by Hopley (1982, 1983) for the reefs of the Great Barrier Reef. Hopley's (1982) classification system i...

The offshore coral reefs of Indonesian Archipelago exhibit a high degree of geomorphological complexity. Reef types present range from the classical Darwinian barrier reefs and atolls, to a variety of shelf reefs (e.g., patch and barrier) and oceanic platform reefs. The vast majority of these reefs are found in the central and eastern parts of the...

Perhaps no geologic structure made by living organisms has fascinated coral reef scientists during the past 150 years as much as have the atolls, jewels of the oceans. Atolls are widely scattered throughout the tropical and subtropical Indo-Pacific, with a few in the tropical western Atlantic. Darwin (1842) provided the first detailed account of th...

Coral cays are generally referred to as low islands constructed entirely from the biogenic materials of the reef itself (Hopley 1982), and are a common physiographic and ecologic zone of many reefs throughout the archipelago (fig. 17.1) and fig. 17.2). The purely biogenic origin of coral cay sediments, from the underlying reef, and the absence of c...

The Indonesian Archipelago is one of the most complex marine domains on the planet.

Prior to 1911, very little was known about the nature or the general distribution of coral reefs within the Indonesian Archipelago. The earliest synthesis of information on the distribution and the type of coral reefs in the archipelago appeared in Darwin's 1842 monumental work on the structure and evolution of coral reefs, which also included the...

Even though scleractinian corals are the primary builders of present-day coral reefs, skeletal material of other groups, both plant and animal, is incorporated into the construction of the reef matrix. In fact, incorporation, cementation and consolidation of all these calcareous materials, including the corals, is a primary requirement of reef buil...

The Protozoa is a diverse assemblage of single-celled organisms found in most aquatic environments sustaining life. Foraminifera are shell-bearing (i.e., test) rhizopods (Order Foraminiferida), that are one of the most abundant groups of small marine and estuarine protozoa (Phleger 1960; Lee 1974; Bé 1977; Boersma 1978).

To gain an appreciation of the diverse nature of coral reef systems in the vast Indonesian archipelago, some understanding of basic coral taxonomy and biology is helpful. This is especially true for systems where one particular assemblage of organisms can be considered as the "ecological dominants". Reef-building corals (Scleractinia) are such a gr...

Like many other biological systems, coral reef communities are subjected to a variety of environmental disturbances of varying intensity, frequency and duration (Pearson 1981; Huston 1985; Karlson and Hurd 1993). The nature and magnitude of impacts associated with the various natural disturbances, therefore, also varies with the nature and intensit...
