CHICAGO (Reuters) - Ships entering the Great Lakes should be made to kill all the creatures that hitch a ride in their ballast tanks, environmental groups said on Tuesday, challenging as too lax a proposed government standard to combat invasive species.
Marine risk from skeleton fighting shrimpNew Zealand Herald | 07 Feb 2012
A crustacean branded a 'skeletal alien invader' could be threatening New Zealand's marine biodiversity, marine scientists say. The National Institute of Water and Atmospheric Research (NIWA) has issued a warning about the spread of skeleton shrimps called Caprella mutica in New Zealand waters.
Ship sounds causing dirty hullsNew Zealand Herald | 03 Feb 2012
Barnacles, mussels and other sea creatures which cling to ships' hulls - costing the shipping industry millions of dollars each year - are attracted by the underwater sounds the vessels generate, research has found.

Motutapu: Precious wildlife on city doorstepNew Zealand Herald | 04 Jan 2012
Motutapu's precious pest-free status was shattered when a stoat was discovered on bordering island Rangitoto after swimming an incredible 3km across the Hauraki Gulf. One male stoat, while not as dangerous as a fecund female, can kill 100 birds in a month, or wipe out an entire population of saddlebacks.
EBRD backs marine bio-safety initiativeebrd.com | 31 Oct 2011
An innovative programme to protect marine biodiversity, backed by the European Bank for Reconstruction and Development, is about to enter a new phase. The project aims to tackle one of the greatest threats to the health of the worlds oceans – the global spread of invasive species and pathogens in the ballast tanks of international cargo vessels.
King crabs threaten seafloor life near AntarcticaScienceDaily.com | 09 Sep 2011
Scientists speculate that the long absence of crushing predators has allowed the evolution of a unique Antarctic seafloor fauna with little resistance to predatory crabs. A recent study indicates that one species of king crab has moved 120 km across the continental shelf in West Antarctica and established a large, reproductive population in the Palmer Deep along the west Antarctic Peninsula.
Climate change sees giant crabs invade the AntarcticThe Independent UK | 07 Sep 2011

Lionfish Spotted in Flower Garden Banks National Marine SanctuaryNOAA's National Ocean Service | 24 Aug 2011
Several juvenile lionfish, normally native to the Indo-Pacific, were spotted recently in NOAA's Flower Garden Banks National Marine Sanctuary, located 70 to 115 miles off the coasts of Texas and Louisiana in the Gulf of Mexico. This is the first instance of lionfish in the sanctuary since the species spread to U.S. East Coast waters in 2000.
Destructive Chinese snail found in Argentine watersfishupdate.com | 10 Aug 2011
A snail from China, which eats mainly mussels, oysters and clams, may cause the collapse of several national fisheries in Argentina, it is feared, as it did in Asia a number of years ago.
Identical virus, host populations can prevail for centuries, WHOI researcher reportsEurekAlert | 22 Jul 2011
(Woods Hole Oceanographic Institution) A Woods Hole Oceanographic Institution scientist, analyzing ancient plankton DNA signatures in sediments of the Black Sea, has found for the first time that the same genetic populations of a virus and its algal host can persist and coexist for centuries. The findings have implications for the ecological significance of viruses in shaping algae ecosystems in the ocean, and perhaps fresh water as well.
Study shows small-scale fisheries' impact on marine lifeScienceDaily.com | 20 Jul 2011
Small-scale fisheries could pose a more serious threat to marine life than previously thought. Research shows that tens of thousands of turtles from across the Pacific are being captured through the activities of small-scale fisheries.
Sea urchins cannot control invasive seaweedsScienceDaily.com | 14 Jul 2011
Exotic marine species, including giant seaweeds, are spreading fast, with harmful effects on native species, and are increasingly affecting the biodiversity of the Mediterranean seabed. Some native species, such as sea urchins (Paracentrotus lividus), can fight off this invasion, but only during its early stages, or when seaweed densities are very low.
Voyage to eradicate rats and save birdsThe Independent UK | 26 Jun 2011
