Coral Reef Fish Connections Are Much More Complex
2012-09-04 04:00:27

April Flowers for redOrbit.com - Your Universe Online Ocean scientists have known for a long time that juvenile coral reef fishes use coastal seagrass and mangrove habitats as nurseries, before they move into the coral reefs as adults. According to a study published in Proceedings of the National Academy of Sciences, the fishes' movements, and the connections between different tropical habitats, are much more complex than previously realized. Despite several studies that have...

Lee Rannals for redOrbit.com — Your Universe Online [ Watch the Video ] Simulations have helped scientists answer some lingering questions regarding the evolution of fish group formation. Researchers reported in the journal Science that they have found evidence that collective motion in animal groups like schools of fish can evolve as a finely tuned defense against attack from predators. Iain Couzin, an assistant professor of ecology and evolutionary biology at Princeton who...

Marine Protection Gets Local Boost In Fiji
2012-08-22 12:14:26

A new study by researchers from the Global Change Institute at the University of Queensland, the ARC Centre of Excellence for Coral Reef Studies at James Cook University, and the Wildlife Conservation Society has found that locally managed marine protected areas within Fiji are playing an increasingly important role in the nation's strategy to protect inshore habitats. The study estimates that by 2020, locally managed marine protected areas within the Fiji Locally Managed Marine Area...

Life in the world´s oceans faces far greater change and risk of large-scale extinctions than at any previous time in human history, a team of the world´s leading marine scientists has warned. The researchers from Australia, the US, Canada, Germany, Panama, Norway and the UK have compared events which drove massive extinctions of sea life in the past with what is observed to be taking place in the seas and oceans globally today. Three of the five largest extinctions of the past...

Unless Drastic Protection Policies Are Put In Place Marine Species Are At Risk
2012-08-21 13:56:55

redOrbit Staff & Wire Reports - Your Universe Online If the levels of carbon dioxide continue to increase many marine species will be harmed or won't survive It is doubtful that the current protection policies and management practices will be enough to save them. If various marine species are to survive, unconventional, non-passive methods to conserve marine ecosystems need to be considered. A group of scientists led by University of California, Santa Cruz researcher and...

Improving Water Quality May Help Save Coral Reefs
2012-08-20 16:58:26

redOrbit Staff & Wire Reports - Your Universe Online It has been found that an unevenness of nutrients in reef waters can increase the bleaching vulnerability of reef corals according to Research from the University of Southampton and the National Oceanography Centre, Southampton. Numerous polyps jointly forming a layer of living tissue that cover the calcareous skeletons make up the corals. Single-celled algae called zooxanthellae, which live within the coral polyps, is what they...

Atlantic Ocean Gets Hit With Invasive Brittle Star Species

redOrbit Staff & Wire Reports - Your Universe Online The appearance and ecology of Atlantic coral reef habitats could be altered by yellow brittle star A study co-written by Dr. Gordon Hendler of the Natural History Museum of Los Angeles County (NHM) about an invasive species of brittle star, Ophiothela mirabilis, has been published online in Coral Reefs, the Journal of the International Society for Reef Studies. Growing populations have established themselves at distant points in...

In the long term, the industry will benefit from measures taken to prevent overfishing, such as the license buyback scheme. This scheme will have broad ranging implications for industry revenue. It may reduce the number of establishments given the paucity of licenses, but it also may allow larger catches with fewer operators, increasing economies of scale and possibly make those companies that remain more profitable. For these reasons, industry research firm IBISWorld has added a report on...

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...
