September, 2004 - A rare reef fish called the humphead wrasse should be guarded from overfishing, experts have claimed.
The WWF and the IUCN-World Conservation Union are set to ask an international trade watchdog to include the fish on its list of protected species.
The Convention on International Trade in Endangered Species (Cites) will have its biennial meeting in October to review the vulnerability of several species.
Conservationists hope the humphead wrasse ... [More]

February, 2002 - Sharks have long been demonised. Many people regard them as malicious man-eaters and believe the best shark is a dead shark.
So why would the death of large, solitary animal warrant cause for concern?
Simple. The mako shark pictured above was the victim of illegal fishing in one of the most important coral seas in the world.

Species All But Disappeared from Gulf of Mexico in 50 Years, by John Nielsen
All Things Considered, July 8, 2004 · Common wisdom holds that a glimpse of the oceanic whitetip shark is a rare one. Researchers say the shark, which lives in tropical water like the Gulf of Mexico, has never been very abundant.
But, as NPR's John Nielsen reports, a new study tells a very different story. As recently as 50 years ago, the whitetip may have once outnumbered all the other big fi... [More]

Christian-right views are swaying politicians and threatening the environment, by Glenn Scherer, 27 Oct 2004
Abortion. Same-sex marriage. Stem-cell research.
U.S. legislators backed by the Christian right vote against these issues with near-perfect consistency. That probably doesn't surprise you, but this might: Those same legislators are equally united and unswerving in their opposition to environmental protection.

By Susan Milius, August 25th, 2004 - Sportfishing isn't just a tiny, harmless nibble on saltwater-fish populations, according to a new analysis of federal data.
For species flagged for special concern in U.S. waters, sportfishing accounts for 23 percent of the harvest, says Felicia Coleman of Florida State University in Tallahassee. The percentage is even higher for certain regions. In the Gulf of Mexico, recreation takes 64 percent of the catch for troubled fish stocks, Coleman and h... [More]

27 July, 2002 - The discovery of two dead seals on a Lincolnshire beach has sparked fears of a fresh outbreak of a fatal virus in UK waters.
Some 18,000 seals in northern Europe died of the highly infectious phocine distemper virus (PDV) in 1988.
The virus returned to Denmark in May 2002 and has so far killed 2,000 seals in Denmark, Sweden and the Netherlands.
Wildlife experts say it is only a matter of time before the disease return to British shores.

Marine Biology News :: ScienceDaily
Satellite tracking of threatened loggerhead sea turtles has revealed two previously unknown feeding "hotspots" in the Gulf of Mexico that are providing important habitat for at least three separate populations of the turtles.
Around 250 million years ago, most life on Earth was wiped out in an extinction known as the "Great Dying." Geologists have learned that the end came slowly from thousands of centuries of volcanic activity.
Scientists have advanced a method that allowed them to single out a marine microorganism and map its genome even though the organism made up less than 10 percent of a water sample teeming with many millions of individuals from dozens of identifiable groups of microbes.
Around the world coral reefs are facing threats brought by climate change and dramatic shifts in sea temperatures. While warming has been the primary focus for scientists and ocean policy managers, cold can also cause significant damage. Scientists have shown that cool temperatures can inflict more damage in the short term, but heat is more destructive in the long run.
Evidence is lacking that populations of jellyfish and similar gelatinous plankton are surging in numbers globally and will likely dominate the seas in coming decades. Rather, increasing scientific and media interest as well as the lack of good baseline data seem to explain the widespread perception of an increase.
Blooms, or proliferation, of jellyfish have shown a substantial, visible impact on coastal populations -- clogged nets for fishermen, stinging waters for tourists, even choked intake lines for power plants -- and recent media reports have created a perception that the world's oceans are experiencing increases in jellyfish due to human activities such as global warming and overharvesting of fish. Now, a new study questions claims that jellyfish are increasing worldwide and suggests claims are not supported with any hard evidence or scientific analyses to date.
A global study has questioned claims that jellyfish are increasing worldwide. Blooms, or proliferation, of jellyfish have shown a substantial, visible impact on coastal populations -- clogged nets for fishermen, stinging waters for tourists, even choked intake lines for power plants -- and recent media reports have created a perception that the world's oceans are experiencing increases in jellyfish due to human activities such as global warming and overharvesting of fish. Now, a new global and collaborative study questions claims that jellyfish are increasing worldwide and suggests claims are not supported with any hard evidence or scientific analyses to date.
Humpback whales on both sides of the southern Indian Ocean are singing different tunes, unusual since humpbacks in the same ocean basin usually all sing very similar songs.
Killer whales are the top marine predator. The increase in hunting territories available to killer whales in the Arctic due to climate change and melting sea ice could seriously affect the marine ecosystem balance. New research has combined scientific observations with Canadian Inuit traditional knowledge to determine killer whale behavior and diet in the Arctic.
Over dinner on R.V. Calypso while anchored on the lee side of Glover's Reef in Belize, Jacques Cousteau told Phil Dustan that he suspected humans were having a negative impact on coral reefs. Dustan -- a young ocean ecologist who had worked in the lush coral reefs of the Caribbean and Sinai Peninsula -- found this difficult to believe. It was December 1974. But Cousteau was right. During the following three-plus decades, Dustan, an ocean ecologist and biology professor at the University of Charleston in South Carolina, has witnessed widespread coral reef degradation and bleaching from up close.
Fish biologists conducted one of the first studies of deep-sea fish sounds in more than 50 years, 2,237 feet under the Atlantic. With recording technology more affordable, fish sounds can be studied to test the idea that fish communicate with sound, especially those in the dark of the deep ocean.
Discoveries made in some underwater caves by researchers in the Bahamas could provide clues about how ocean life formed on Earth millions of years ago, and perhaps give hints of what types of marine life could be found on distant planets and moons.
If you were a blind, cannibalistic sea slug, living among others just like you, nearly every encounter with another creature would require a simple cost/benefit calculation: Should I eat that -- or flee? In a new study, researchers report that these responses are linked to a simple circuit in the brain of the sea slug Pleurobranchaea.
Each year around 20,000 people are infected by nematodes of the genus Anisakis and suffer from illnesses ranging from gastrointestinal diseases to serious allergic reactions as a result. For the first time, parasitologists have gathered data on the occurrence of the parasitic worm and have modeled the worldwide distribution of individual species in the ocean. The resulting maps not only enable statements to be made on the occurrence and migration behavior of certain hosts of the parasites, such as Baleen or toothed whales, but also provide conclusions on the risk of human infection.
The mating habits of marine turtles may help to protect them against the effects of climate change. The study shows how the mating patterns of a population of endangered green turtles may be helping them deal with the fact that global warming is leading to a disproportionate number of females being born.
Microbiologists have found that the microbes that thrive on hot fluid methane and sulfur spewed by active hydrothermal vents are supplanted, once the vents go cold, by microbes that feed on the solid iron and sulfur that make up the vents themselves.
The fate of the world's great whale species commands global attention as a result of heated debate between pro and anti-whaling advocates, but the fate of smaller marine mammals is less understood, specifically because the deliberate and accidental catching and killing of dolphins, porpoises, manatees, and other warm-blooded aquatic species are rarely studied or monitored.
Lessons from tens of millions of years ago are pointing to new ways to save and protect today's coral reefs and their myriad of beautiful and many-hued fishes at a time of huge change in the Earth's systems. Today's complex relationship between fishes and corals developed relatively recently in geological terms -- and is a major factor in shielding reef species from extinction, say experts.
Recent carbon dioxide emissions have pushed the level of seawater acidity far above the range of the natural variability that existed for thousands of years, affecting the calcification rates of shell-forming organism.
Rising human carbon dioxide emissions may be affecting the brains and central nervous system of sea fishes with serious consequences for their survival, an international scientific team has found. Carbon dioxide concentrations predicted to occur in the ocean by the end of this century will interfere with fishes' ability to hear, smell, turn and evade predators, says a professor.
