Biogeoscientists show evidence of 90 billion tons of microbial organisms -- expressed in terms of carbon mass -- living in the deep biosphere. This tonnage corresponds to about one-tenth of the amount of carbon stored globally in tropical rainforests. Archaea were found to make up at least 87 percent of organisms that colonize the deep biosphere. This finding is in stark contrast to previous reports, which suggest that Bacteria dominate the subseafloor ecosystem. View the full article

Unknown schooling fish ID
Achilles Tang replied to xnsdvd's topic in New to the Marine Aquaria Hobby
Looks like some kind of wrasse. -
ANY form of wave/current-making pump aimed DIRECTLY at a coral will cause it stress, even some SPS. 'Pratas' would be perfectly fine as long as you don't do the above to it. Your concern should be if there is too much hard debris flying around the tank that could pierce the soft tissue of corals, directly or indirectly eg. caused the coral to topple onto LR/another coral or vice versa.

Saharan dust storms help sustain life over extensive regions of the North Atlantic Ocean. Scientists mapped the distribution of nutrients including phosphorous and nitrogen and investigated how organisms such as phytoplankton are sustained in areas with low nutrient levels. They found that plants are able to grow in these regions because they are able to take advantage of iron minerals in Saharan dust storms. View the full article

University of Alberta scientists contend they have the answer to mass extinction of animals and plants 93 million years ago. The answer, research has uncovered, has been found at the bottom of the sea floor where lava fountains erupted, altering the chemistry of the sea and possibly of the atmosphere. View the full article

It's a long way from the dull hums of the amorous midshipman fish to the strains of a Puccini aria -- or, alas, even to the simplest Celine Dion melody. But the neural circuitry that led to the human love song -- not to mention birdsongs, frog thrums and mating calls of all manner of vertebrates -- was likely laid down hundreds of millions of years ago with the hums and grunts of the homely piscine.

Antarctic worms, sea spiders, urchins and other marine creatures living in near-shore shallow habitats are regularly pounded by icebergs. New data suggests this environment along the Antarctic Peninsula is going to get hit more frequently. This is due to an increase in the number of icebergs scouring the seabed as a result of shrinking winter sea ice, according to a study in the journal Science. View the full article

Many species must move to new areas to survive climate change. Often, this seems impossible. Species stranded on mountain tops in southern Europe that are becoming too hot for them, for instance, are unlikely to be able to reach northern Europe unaided. So should humans step in to help? The journal Science reports that conservation scientists are calling for new conservation tactics, such as assisted migration, in the face of the growing threat of climate change.

The invasion of predatory lionfish in the Caribbean region poses yet another major threat there to coral reef ecosystems -- a new study has found that within a short period after the entry of lionfish into an area, the survival of other reef fishes is slashed by about 80 percent.

Sight and hearing are the most important senses for birds -- this is at least the received wisdom. By studying bird DNA, however, researchers have now provided genetic evidence that many bird species have a well-developed sense of smell. View the full article

They should ban damselfishes too in this case... they bite hard!

Not much is known about the world's largest living turtle, the leatherback. So-called for its tough, oily skin and lack of a hard shell, the behavior and habitats of this critically endangered turtle have remained a mystery. Marine biologists have just completed the largest study to date on leatherback turtles, unveiling the turtles' behavior, in doing so, providing methods that could be used to protect them.

Re-seeding programs on over 50 reefs are securing the survival of the giant clam for at least another generation. The clams, the world's largest bivalve mollusks and the star of lurid but mostly imaginary literary and cinematic depictions of trapped divers, can live for over a century. They have been known to exceed 1.4 meters in length and weigh in at over 260 kilograms. View the full article
