Health Of Marine Ecosystems Associated With Health Of Manatees
2012-10-03 12:40:10

April Flowers for redOrbit.com - Your Universe Online A team of scientists, led by George Mason University, have conducted a long-term study of manatees which may be a benchmark in determining health threats to marine mammals. The study, which ran over ten years in Belize, examined the behavioral ecology, life history and health of manatees in an area relatively undisturbed by humans. “Manatees are the proverbial ℠canaries in the mineshaft,´ as they serve as indicators...

Ocean Warming Is Shrinking Fish Size
2012-10-01 09:33:57

Brett Smith for redOrbit.com - Your Universe Online New research by a team of North American scientists indicates that warmer water may cause shrinkage in average fish size and populations of fish stocks. "We were surprised to see such a large decrease in fish size," said William Cheung, a professor at the University of British Columbia and lead author of a report on the team´s research that was published in the journal Nature Climate Change. "Marine fish are generally known to...

Clues Captured For Sustainability Of Fish Populations
2012-09-28 10:33:22

Thanks to studies of a fish that gives birth to live young and is not fished commercially, scientists at UC Santa Barbara have discovered that food availability is a critical limiting factor in the health of fish populations. The scientists were able to attach numbers to this idea, based on 16 years of data. They discovered that the availability of enough food can drive up to a 10-fold increase in the per capita birthrate of fish. And, with adequate food, the young are up to 10 times more...

Coral Hotspots Found In Deepwater Canyons
2012-09-28 04:33:26

Alan McStravick for redOrbit.com - Your Universe Online When most people think of coral reefs, they are transported to temperate waters in a tropical locale. To even locate a coral ecosystem in the cold waters of the mid and north Atlantic would be a difficult endeavor. Or, at least, one would have thought. A recent exploration of the continental shelf and slope of the Northeastern United States has revealed coral hotspots. These are areas that have an abundance of sea life existing in...

Coral Algae Overgrowth Endangers Whole Ecosystems
2012-09-20 11:55:50

April Flowers for redOrbit.com - Your Universe Online Overfishing and nitrate pollution can destroy coral reefs by allowing an overgrowth of algae that brings with it unwanted pathogens, chokes off oxygen and disrupts helpful bacteria. These are the findings of a new study out of the Oregon State University, published recently in PLoS One. Large algal species, or "macroalgae," are big enough to essentially smother corals. These macralgae grow at accelerated rates when sewage waste...

Coral Reefs Will Suffer If Climate Change Goes Unchecked
2012-09-17 12:17:18

Brett Smith for redOrbit.com - Your Universe Online Time may be running out for the world´s coral reefs which could be severely victimized by rising global temperatures and carbon dioxide levels, according to a new report in Nature Climate Change. "Our findings show that under current assumptions regarding thermal sensitivity, coral reefs might no longer be prominent coastal ecosystems if global mean temperatures actually exceed 2 degrees Celsius (3.6 Fahrenheit) above the...

First-time Analysis Provided Of 3 Distinct Contributions Of Forage Fish Worldwide
2012-09-10 11:43:12

Study led by scientists from the Institute for Ocean Conservation Science at Stony Brook University will enable trade-offs to be evaluated in forage fishery and coastal management A just-published study provides a first-time analysis of the value of forage fish, which are small, schooling species such as sardines, herring, and anchovies. Three kinds of contributions of forage fish were estimated: as direct catch, as food for other commercially important fish, and as an important link in...

April Flowers for redOrbit.com - Your Universe Online How can sea otters change the world? A new study, led by the University of California, Santa Cruz, suggests that a thriving population of sea otters will keep the sea urchins in check, which will in turn allow kelp forests to prosper.  Spreading kelp forests can absorb as much as 12 times the amount of CO2 from the atmosphere than if it were subject to sea urchin ravaging. "It is significant because it shows that animals can...

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...

This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
