University of New South Wales The migration of tropical fish as a result of ocean warming poses a serious threat to the temperate areas they invade, because they overgraze on kelp forests and seagrass meadows, a new study concludes. The harmful impact of tropical fish is most evident in southern Japanese waters and the eastern Mediterranean, where there have been dramatic declines in kelps. There is also emerging evidence in Australia and the US that the spread of tropical fish...

Fukushima Radiation May Be Lurking In West Coast Kelp Forests

Brett Smith for redOrbit.com - Your Universe Online With radiation-tainted waters from the Fukushima nuclear disaster expected to wash up on American shores this year, California scientists are taking steps to monitor West Coast waters for radioactivity. According to a U-T San Diego report, researchers from San Diego State University will begin testing kelp beds off the coast of California for radiation levels. The San Diego scientists said hazardous radioisotopes cesium-134 and...

University of Adelaide marine biologists have found that reducing nutrient pollution in coastal marine environments should help protect kelp forests from the damaging effects of rising CO2. The researchers have found a combined effect on kelp forests from nutrient pollution and higher CO2, which could have a devastating impact on Australia's marine ecosystems. "When we manipulated CO2 and nutrient levels in an experimental marine ecosystem we found the effect of both of them together...

There´s a new seaweed in town, a brown, bulbous balloon befitting the nickname “sea potato.” Its New England debut was spotted by two University of New Hampshire plant biology graduate students; now researchers are keeping a close eye on the sea potato´s progress to determine whether there is cause for alarm. UNH graduate students Lindsay Green and Hannah Traggis discovered the rapid southern expansion of Colpomenia peregrina, also known as sea potato or oyster thief,...

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...

Scientists have for the first time determined the complete genome sequence of a brown alga and opened a new door to the understanding of multicellularity and photosynthesis. With the world's first complete sequencing of a brown algal genome, an international research team has made a big leap towards understanding the evolution of two key prerequisites for higher life on Earth - multicellularity and photosynthesis. As the internationally renowned science magazine "Nature" reported in its...

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...
