Invasive Species (Page 2)
What is an invasive species (and why you should care)?NOAA's National Ocean Service | 29 Feb 2012Did you know that Feb. 27 through March 3 is National Invasive Species Awareness Week? Invasive species are a big problem in the U.S. and around the world. We've put together a handy resource to help you learn more about aquatic invasive species.
Invasive Species Marine risk from skeleton fighting shrimpNew Zealand Herald | 07 Feb 2012A 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.
Pacific Ocean | Invasive Species Ship sounds causing dirty hullsNew Zealand Herald | 03 Feb 2012Barnacles, 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.
Invasive Species | Sea Transport Motutapu: Precious wildlife on city doorstepNew Zealand Herald | 04 Jan 2012Motutapu'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.
Pacific Ocean | Invasive Species | Seabirds EBRD backs marine bio-safety initiativeebrd.com | 31 Oct 2011An 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.
Biodiversity | Invasive Species King crabs threaten seafloor life near AntarcticaScienceDaily.com | 09 Sep 2011Scientists 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.
Southern Ocean | Climate Change | Invasive Species 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.
Invasive Species | Research Sea urchins cannot control invasive seaweedsScienceDaily.com | 14 Jul 2011Exotic 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.
