Duncanopsammia axifuga (Scleractinia: Dendrophylliidae) is reported for the first time from Indonesia. A population was found in 5-m deep, murky water on a sediment-rich, inshore reef at Bird’s Head Peninsula, West Papua. Some corals were attached to dead coral and others were loose fragments living on sediment. One attached specimen was observed t...

Indonesia’s coral reefs have been severely damaged by global and local stressors, and a range of active restoration techniques are now being used in attempts to rebuild degraded reefs. However, it is difficult to summarise Indonesia’s restoration efforts as a whole due to a lack of consistent reporting. Here, we first discuss Indonesia's legal poli...

Broad-scale studies and regional comparisons of Indonesia’s coral reefs are critical given the relative lack of information about these large, diverse, and threatened ecosystems. Most studies on reef benthic composition and distribution have largely focused on rather short transects spanning relatively small areas. Here, we quantify the shallow lar...

As oceans continue to warm under climate change, understanding the differential growth responses of corals is increasingly important. Scleractinian corals exhibit a broad range of life-history strategies, yet few studies have explored interspecific variation in long-term growth rates under a changing climate. Here we studied growth records of two c...

Studies on the growth response of corals to changing climate have largely focused on long-lived corals with relatively distinct density bands such as massive Porites corals. Little is known about the climatic response of other more abundant growth forms, such as branching Acropora corals, largely because of the absence of a clear annual density ban...

Under projections of global climate change and other stressors, significant changes in the ecology, structure and function of coral reefs are predicted. Current management strategies tend to look to the past to set goals, focusing on halting declines and restoring baseline conditions. Here we explore a complementary approach to decision making that...

M. boschmai. This revision of Indonesian Millepora species is based on the morphology of museum specimens and photographed specimens in the field. Based on the use of pore characters and overall skeleton growth forms, which are normally used for the classification of Millepora, the present study concludes that six of seven Indo-Pacific species appe...

Between 1.5 and 2 million people worldwide are believed to keep marine aquaria. The trade which supplies this hobby with live marine animals is a global multi-million dollar industry, worth an estimated US$200-330 million annually, and operating throughout the tropics. Ornamental marine species (corals, other invertebrates and fish) are collected a...
