Latest Kelp forest Stories
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.
Northeastern University ecologist David Kimbro claims to have watched a lot of TV growing up, particularly The Brady Bunch. “You could kind of get a flavor for how an episode was going to turn out based on how Jan or Peter were faring—you know, the middle kids,” said Kimbro, an assistant professor in the Department of Marine and Environmental Sciences.
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.
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.
Predation by otters keeps urchin populations in check, allowing kelp –– a favorite food of urchins –– to flourish.
A thriving population of sea otters will keep sea urchins in check, which will allow kelp forests to prosper and allow them to absorb 12 times the amount of CO2 than if they were subject to sea urchin ravaging.
Coral reefs and seashores largely look the way they do because large fish and urchins eat most of the seaweed that might otherwise cover them, but a major new study has found that the greatest impact of all comes from an unexpected quarter – small marine snails.
Marine scientists discover wave disturbance, nutrient levels affect California giant kelp growth.
Scientists at UC Santa Barbara have developed new methods for studying how environmental factors and climate affect giant kelp forest ecosystems at unprecedented spatial and temporal scales.
A new analysis of the extinction of woolly mammoths and other large mammals more than 10,000 years ago suggests that they may have fallen victim to the same type of "trophic cascade" of ecosystem disruption that scientists say is being caused today by the global decline of predators such as wolves, cougars, and sharks.
The Bocaccio (Sebastes paucispinis) is a member of the Sebastidae rockfish family. Other names regarding this species include the Salmon Grouper, Grouper, Tom Cod referring to juveniles, and Slimy. In Greek, sebastes means “magnificent” and paucispinis is Latin for “few spines”. These fish can be found from Stepovak Bay, Alaska to central Baja California, but is mostly abundant from Oregon to the northern part of Baja California. They have been seen from a variety of depths from...
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...
The Horn Shark (Heterodontus francisci) is a species of bullhead shark that ranges from central California to the Gulf of California, Mexico, and possibly Ecuador and Peru. Its habitat includes rocky reefs, kelp beds, sand flats, crevices, and caverns at depths from 7 to 490 feet. It is mostly nocturnal and is rather sluggish in the daytime. The adult can reach a length of 4 feet and weigh about 22 pounds. It is brown with black spots. If harassed it may bite. It has poisonous spines on...
The sea otter (Enhydra lutris) is a large otter native to the North Pacific, from northern Japan and Kamchatka east across the Aleutian Islands south to California. The heaviest of the otters, sea otters are the only species within the genus Enhydra. They were hunted extensively for their luxurious fur. Its estimated that a half million to a million otters were killed over time. The population is thought to have been 150,000 to 300,000 historically before the years of the great hunt....
- In Roman antiquity, the return of a person who had been banished, or taken prisoner by an enemy, to his old condition and former privileges.
- In international law, that right by virtue of which persons and things taken by an enemy in war are restored to their former status when coming again under the power of the nation to which they belonged.
