Biologists have presented the first evidence that areas closed to all fishing are helping to sustain valuable Australian fisheries. The scientists applied a forensic DNA profiling approach to track the dispersal pathways of fish larvae throughout a network of marine reserves on Australia's Great Barrier Reef.

Most people are fascinated by the colorful and exotic coral reefs, which form habitats with probably the largest biodiversity. But human civilization is the top danger to these fragile ecosystems through climate change, oxygen depletion and ocean acidification. Industrialization, deforestation and intensive farming in coastal areas are changing dramatically the conditions for life in the oceans. Now scientists have investigated how and why the corals die when exposed to sedimentation. According to their findings, oxygen depletion, together with an acidification of the environment, creates a chain reaction that leads to coral death.

As the popularity of marine aquariums rises, so does the demand for wildlife inhabiting them. Most aquarium fish are harvested from their natural habitats -- primarily coral reefs -- and imported into the United States by the millions annually.

Groupers, a family of fishes often found in coral reefs and prized for their quality of flesh, are facing critical threats to their survival. Scientists report that 20 species are at risk of extinction if current overfishing trends continue, and an additional 22 species are near "threatened" status.

Jobs, livelihoods and ecotourism industries can benefit from having a diverse supply of weed-eating fish on the world's coral reefs, marine researchers say. Despite their small size, relative to the sharks, whales, and turtles that often get more attention, herbivorous fish play a vital role in maintaining the health of coral reefs, which support the livelihoods of 500 million people worldwide, say researchers.

Scientists predict ocean temperatures will rise in the equatorial Pacific by the end of the century, wreaking havoc on coral reef ecosystems. But a new study shows that climate change could cause ocean currents to operate in a way that mitigates warming near a handful of islands right on the equator.

Scientists have predicted that ocean temperatures will rise in the equatorial Pacific by the end of the century, wreaking havoc on coral reef ecosystems. But a new study shows that climate change could cause ocean currents to operate in a surprising way and mitigate the warming near a handful of islands right on the equator. As a result these Pacific islands may become isolated refuges for corals and fish.
