Healthy coral reefs of Madagascar resisting damage from climate change

...ence and 17 others noted for the first time in the waters off Madagascar. These findings, combined with results of a similar survey in 2002 along northwest Madagascar's coast, increased to 829 the total number of fish species in Malagasy waters. The two Rapid Assessment Program (RAP) expeditions also recor...

How satellite tracking revealed the migratory mysteries of endangered Atlantic loggerhead turtles

...were incidentally caught by fisherman scouring the waters for other species such as tuna and swordfish. Of these, tens of thousands are thought to die as a result. 37% of this fishing effort was in the Atlantic and a major hotspot for fishing is found off West Africa, the region where the Cape Verdean turtl...

Drug discovery team to explore newly discovered deep-sea reefs

From May 22-26, the team will be working at sites on the Bahamas side of the Straits of Florida, about 10 miles from Bimini. From May 27-...

Researchers discover which organs in Antarctic fish produce antifreeze

...chers also studied a variety of fishes from Arctic waters that have liver expression of AFGPs, and found that all of them also express antifreeze in the pancreas. The findings, they wrote, bring a new perspective to teleost freeze-avoidance physiology and "reveals that the long-held paradigm of hepatic-bas...

Arctic coring expedition continues to yield new clues

ACEX, only the second scientific expedition to be conducted by the Integrated Ocean Drilling Program (established 2003), recovered 339 meters of subseafloor sediment samples. "Building a picture of ancient climatic events is a...

While scientists cannot yet fully predict how much marine calcification rates will change in the future, the report warns that the more critical questio...

A giant among minnows: Giant danio can keep growing

...nts of home aquariums. They are native to the warm waters around India and some other areas of southern Asia. Although both are small, the danio is a giant among minnows, growing to a maximum of six inches. The zebrafish, in contrast, grows to about two inches. The zebrafish has been a staple of genetic r...

From hot springs to rice farms, scientists reveal new insights into the secret lives of archaea

...olds the world temperature record for surviving in waters of 113 C or 235 F, well above the boiling point. ''However, in the early '90s, it was discovered that non-extremophilic archaea were ubiquitous and abundant in the marine environment, but it was unclear exactly how these organisms were making a li...

Fishy cooperation

Prey can escape from the grouper by hiding in a crevice and from the moray eel by leaving the reef, but prey has nowhere to go if hunted by a combination of these two predators. The article offers a description and accompanying vide...

Tiny Tampa Bay fish key to evolution of immune system

... hardier than the version found in people. The bay waters are a microbial soup teeming with microorganisms, yet the worm-like bottom-feeder is remarkably adept at standing up to the bacterial, viral and chemical threats in its environment. Understanding how it does so could lead to improved biodefense and b...

NASA satellite data helps assess the health of Florida's coral reef

... reef health. Bleaching events typically peak when waters reach their warmest levels, usually in late summer and early fall. Phenomena like El Niño have also been linked to declines in reef health. During the strong El Niño of 1998, about 30 percent of coral off the Florida Keys died after a single mass ble...

And the interlayer surface area is huge (greater than 100 square meters per gram of clay ?bigger than a football field)...
