These days, only four species of Sirenian, more commonly known as the seacow, manatee or dugong exist in a given world region. Smithsonian scientists, however, have been studying fossil records of the ancient mammals and have discovered evidence that this hasn´t always been the case. According to these fossil records, which date back 50 million years ago, multiple species of seacow once existed together. The research also suggests the environment these seacows resided within, as well as...

Mediterranean seagrass meadows contain genetically identical clones up to 15 kilometers apart, suggesting that these organisms must be thousands to tens of thousands of years old, as reported in the Feb. 1 issue of the online journal PLoS ONE. The seagrass, Posidonia oceanica, reproduces asexually, which can result in single organisms that are very large and very old. To investigate the P. oceanica meadow, the researchers, led by Sophie Arnaud-Haond of the French Research Institute for...

Diminishing nature's carbon storage Australian scientists have reconstructed the past six thousand years in estuary sedimentation records to look for changes in plant and algae abundance. Their findings, published in Global Change Biology, show an increase in microalgae relative to seagrass in the past 60 years. This shift could diminish the ability of estuaries, which are natural global carbon sinks, to mitigate climate change. According to Dr. Peter Macreadie, University of...

The world's coastal marine ecosystems are being overlooked, both in terms of their ecological importance and their potential as a rallying point for conservation. Writing in Aquatic Conservation: Marine and Freshwater Ecosystems Project Seahorse Director Dr. Amanda Vincent argues that increased protections are needed for the first 10 metres of depth of the world's oceans, where the richest diversity of marine habitats and animal life can be found and where most ocean-related human activity...

A team of 21 researchers from 11 nations, including professor Robert "JJ" Orth of the Virginia Institute of Marine Science, has completed the first-ever study of the risk of extinction for individual seagrass species around the world. The 4-year study, requested by the International Union for the Conservation of Nature (IUCN), shows that 10 of the 72 known seagrass species (14%) are at an elevated risk of extinction, while 3 species qualify as endangered. The authors caution that loss of...

As part of the ongoing Natural Resource Damage Assessment (NRDA) that has followed the Deepwater BP oil spill, federal and state partners have reached an agreement with BP to begin a new effort to restore submerged aquatic vegetation that was damaged by response vessels and activities. Emergency restoration projects like this one are intended to reduce or prevent ongoing or potential injuries to natural resources resulting from the spill and related response activities. NOAA will lead the...

MOBILE, Ala., Jan. 24, 2011 /PRNewswire/ -- On January 22-23, 2011, nearly 550 volunteers from Alabama and beyond donned boots and gloves and donated their time to place 16,000 bags of oyster shells along the shore - the first step to building 100 miles of oyster reef over the next three to five years in Mobile, AL. The oyster reef building project marks the first in a series of habitat restoration projects aimed at restoring Alabama's Gulf coast, an effort led by the 100-1000: Restore...

Results of a five-year monitoring effort to repair seagrass damaged in a boat grounding incident suggest that restoration techniques such as replanting seagrass can speed recovery time. The finding is included in a new report released Dec. 16 by NOAA's Office of National Marine Sanctuaries. The National Marine Sanctuaries Conservation Series report, "N-Control Seagrass Restoration Monitoring Report Monitoring Events 2003-2008," presents results of efforts to repair a nearly 1,000-square-foot...

A major new study that sounds a conservation alarm for the world's vertebrate species notes that the world's seagrass species are faring somewhat better, says a University of New Hampshire researcher who was a coauthor of the study. Fred Short, UNH research professor of natural resources and director of the worldwide program SeagrassNet, was among the 174 scientists who contributed to "The Impact of Conservation on the Status of the World's Vertebrates," released online this week in the...

The Slender sea star (Astropecten spinulosus), is a species of starfish in the Astropectinidae family. It is found only in the Mediterranean Sea, spending much of its life on sandy, muddy or gravelly seabed in areas very rich in algae from 3.5 to 165 feet deep. Its favorite seabed meadows are Mediterranean Tapeweed (Posidonia oceanica) and Little Neptune Grass (Cymodocea nodosa). The common name Sea Star is a generic term given to other members of this genus as well. This sea star spends...

The Rusty Carpetshark (Parascyllium ferrugineum) is a species of fish in the family Parascylliidae. It is found off the southern coast of Australia, between latitudes 31° S and 41° S. They are typically found in water at depths between 15 and 500 feet. It occurs on beds of algae on reefs or seagrass, and also hides in rocky caves and ledges during the day. The Carpetshark grows to about 31.5 inches long. The mouth is in front of the eyes. It is gray-brown in color with an unclear...
