Shallow water coral reefs are found in tropical areas, between the Tropics of Cancer and Capricorn to a maximum of about 50–75 m depth, in environments with suitable temperatures, salinity, light, nutrients, sediment, hydrodynamics, and seawater carbonate chemistry. Coral reefs are estimated to cover from 284,300 km2 (Spalding et al. 2001) to about 920,000 km2 when associated habitats are included in calculations (Costanza et al. 1997), with 91% of this area in the Indo-Pacific. The Red Sea, which is considered part of the Indo-Pacific region, contains the most biologically diverse reef communities outside of the Southeast Asia coral...

In the comment on Bruckner (2009; Mar Ecol Prog Ser 397:319–332), Santangelo & Bramanti (2010; Mar Ecol Prog Ser 418:295–297) suggest that the available data for Corallium rubrum populations cannot be used to make conclusions about population trends for the species throughout the Mediterranean. Their main concerns relate to (1) different methodologies used to sample populations; (2) insufficient population information from deep water; and (3) limited data on sampling area and density of colonies. While I recognize many of the limitations of the data, the conclusions in Bruckner (2009) were based on multiple datasets, including population demography and reproductive...

Farasan Islands Habitat Mapping in Saudi Arabia Using CASI and QuickBird Imagery
Map products derived from remote sensing technology increase our understanding and ability to manage tropical marine environments. The enhanced mapping capabilities of hyperspectral sensors are well understood; yet technology uptake, particularly for large scale tasks, has been slow. The study presented represents one of the largest hyperspectral projects to date, and paves the way towards increased use of this technology. Hyperspectral CASI-550 imagery and multispectral QuickBird imagery, was acquired over 3,168 km2 of the Farasan Islands. In addition to the typical image processing steps, inopportune water condensation in the CASI sensors lens necessitated further processing to remove an across-track artifact....

How U.S. Ocean Policy and Market Power Can Reform the Coral Reef Wildlife Trade
As the world’s largest importer of marine ornamental species for the aquaria, curio, home de´ cor, and jewelry industries, the United States has an opportunity to leverage its considerable market power to promote more sustainable trade and reduce the effects of ornamental trade stress on coral reefs worldwide. Evidence indicates that collection of some coral reef animals for these trades has caused virtual elimination of local populations, major changes in age structure, and promotion of collection practices that destroy reef habitats. Management and enforcement of collection activities in major source countries such as Indonesia and the Philippines remain weak....

Terrestrial and Marine Ecology of Marie-Louise, Amirantes, Seychelles
The Amirantes group, Seychelles, comprises 24 islands and islets lying between 5o and 6o south of the equator on the Amirantes Bank, western Indian Ocean. The islands were discovered by the Portuguese navigator Vasco da Gama on his second voyage to India in 1502, soon after acceding to the rank of Admiral, and the islands were subsequently named Ilhas do Almirante or Admiral’s Islands (Lionnet, 1970). The group extends over a distance of 138 km, from African Banks in the north to Desnoeufs in the south. Marie-Louise lies at the southern end of the Amirantes group at 6o10′S, 53o08′E, approximately 13 km from Desnoeufs and 280 km south-west of the granitic island of Mahé (Wilson, 1983)....
