Scientists Analyze Costs And Benefits Of Rock Dissolving Practices
2013-01-22 12:14:08

Brett Smith for redOrbit.com - Your Universe Online Geoengineering is a controversial and illegal practice that attempts to mitigate the forces of climate change on a grand scale. Many see this attempt to alter global climate via artificial means as a ℠quick fix´ with potential long-term negative effects. However, despite the contentious nature of geoengineering, scientists from the Alfred Wegener Institute in Bremerhaven, Germany decided to analyze a ℠rock...

High-Tech Robotic Fish Glides Through Water With Great Ease
2013-01-17 12:54:52

Lee Rannals for redOrbit.com — Your Universe Online Scientists from the Michigan State University made a number of improvements on a high-tech robotic fish. The new fish, called Grace, was designed and built by Xiaobo Tan, an MSU associate professor of electrical and computer engineering, and his team. They equipped the new fish with an array of sensors, allowing it to travel autonomously through the water, as well as measure water temperature, quality and other pacts. These...

Tiny coral reef wrasses can swim as fast as some of the swiftest fish in the ocean — but using only half as much energy to do so, Australian scientists working on the Great Barrier Reef have found. By flapping their fins in a figure-eight pattern, bluelined wrasses can travel at high speeds while using 40 per cent less energy than tunas of the same size. “For a long time, people thought the best high-speed swimmers were the fishes cruising in open waters, like mackerel and...

2013-01-12 10:21:34

Jedidiah Becker for redOrbit.com — Your Universe Online This Sunday, The National Geographic Society will celebrate 125 years of intrepid exploration, pioneering science journalism and dazzling photography. If you´re like us, you can scarcely hear the name “National Geographic” without immediately calling to mind a vision of the magazine´s iconic yellow border framing some breathtaking image or hearing Elmer Bernstein´s rousing fanfare...

Snapshot Of Pupfish Evolution In Action
2013-01-10 15:28:17

University of California - Davis Chris Martin has bred more than 3,000 hybrid fish in his time as a graduate student in evolution and ecology at UC Davis, a pursuit that has helped him create one of the most comprehensive snapshots of natural selection in the wild and demonstrated a key prediction in evolutionary biology. "We can see a surprisingly complex snapshot of natural selection driving the evolution of new specialized species," said Martin, who with Professor Peter Wainwright...

Hawaiian waterfall-climbing fish use same muscles to climb and feed Going against the flow is always a challenge, but some waterfall-climbing fish have adapted to their extreme lifestyle by using the same set of muscles for both climbing and eating, according to research published January 4 in the open access journal PLOS ONE by Richard Blob and colleagues from Clemson University. The Nopili rock-climbing goby is known to inch its way up waterfalls as tall as 100 meters by using a...

Prey Density Is More Important Than Total For Sea Predators
2013-01-04 13:02:20

Brett Smith for redOrbit.com - Your Universe Online As ocean predators comb the waters in search of a food source, they often seek out dense groups of prey to maximize their hunting efforts, according to a new study in the open access journal PLOS ONE. A team of American and Canadian biologists began their study by trying to find out where three different Bering Sea predators — northern fur seals and two different sea birds, black-legged kittiwakes and thick-billed murres —...

Lee Rannals for redOrbit.com - Your Universe Online Scientists have discovered corals at Australia´s Great Barrier Reef at depths that were previously believed to be uninhabitable. A team of researchers with the University of Queensland's Seaview Survey has been working on a multi-year project to map out the Great Barrier Reef, and they recently announced that they have found corals in waters nearly as dark as night. The newly discovered corals sit at 410 feet below the surface at...

Fish Have Huge Nutrient Impacts On Marine Ecosystems
2012-12-12 09:33:47

University of Georgia Fish play a far more important role as contributors of nutrients to marine ecosystems than previously thought, according to researchers at the University of Georgia and Florida International University. In a pair of papers in the journal Ecology, they show that fish contribute more nutrients to their local ecosystems than any other source-enough to cause changes in the growth rates of the organisms at the base of the food web. Jacob Allgeier, a doctoral student in...

Crown Of Thorns Starfish, Acanthaster planci
2013-11-11 10:54:41

The crown-of-thorns starfish (Acanthaster planci) is a species of starfish that is classified within the Acanthasteridae family. This species has a large range that extends from the Red Sea to the African coasts in the east and from the Indian Ocean to the western coasts of Central America. It prefers a habitat in coral reefs, which can be harmed if population numbers are too high. Damage occurs when filamentous algae covers bare skeletons of coral and the starfish move in to feed, stripping...

Bluefish, Pomatomus saltatrix
2013-10-22 10:54:52

The Bluefish (Pomatomus saltatrix) is the only living species of the family Pomatomidae. It is a marine pelagic fish that can be found around the world in temperate and subtropical waters, except for the northern Pacific Ocean. Bluefish are known as tailor in Australia, shad on the east coast of South Africa, and elf on the west coast. Other common names regarding this fish are blue, chopper, and anchoa. It is a good eating and game fish. The bluefish is moderately proportioned with a...

Lampert's Sea Cucumber, Synaptula lamperti
2013-04-30 15:18:06

Synaptula lamperti is a species of sea cucumber that can be found in the waters of the Indo-Pacific. Its range includes the coastal waters of Papua New Guinea, the Philippines, Indonesia, and Micronesia. It does not have the tube feet, which are common to other species of sea cucumber, instead moving around by using a small grouping of pinnate feeding tentacles, which are always moving. It can also move by using the small, hook-like bones found along its body, attaching itself to the sea...

Mudflats
2013-04-19 21:07:34

Mudflats, or otherwise known as tidal flats, are coastal wetlands that form when mud is left behind by tides or rivers. They’re found in sheltered regions such as bayous, lagoons, estuaries, and bays. Mudflats might be seen geologically as exposed layers of bay mud, a result from the deposition of estuarine silts, marine animal detritus, and clays. The majority of the sediment in a mudflat is within the intertidal zone, therefore the flat is submerged and exposed about twice per day. In...

Kelp Forest
2013-04-19 19:29:03

Kelp forests are areas that are underwater with a high density of kelp. They’re recognized as one of the most dynamic and productive ecosystems on Earth. Smaller regions of anchored kelp are known as kelp beds. Kelp forests can be found worldwide throughout polar and temperate coastal oceans. In the year 2007, kelp forests were discovered in tropical waters near Ecuador as well. While they are physically formed by brown macroalgae of the order Laminariales, kelp forests offer a unique...
