Warming by 1C drives species and assemblage level responses in Antarctic's marine shallows

2017-09-13

Ashton et al. describe population to assemblage level responses to the most realistic in situ warming of marine life to date, implemented in Antarctica. These include surprising increases in growth rate with a 1C rise in sea temperature and domination of the benthic community by a pioneer species that dramatically altered community structure.

Invasive isopods in the Salish Sea

2015-01-29

A recent publication on the global introduction of the Asian isopod Ianiropsis serricaudis was a by-product of a study we funded to evaluate the impact of invasive tunicates in the Salish Sea (Cordell et al., 2012). The publication shows that this invasive isopod is often associated with other invasive species and is well-established in communities of fouling organisms throughout the Northern Hemisphere.

Invasive Species Threaten Ecosystems in the Arctic

2014-06-06

Melting sea ice has opened routes in the Arctic — the Northwest Passage and the Northern Sea Route — making a quicker path from one side of the world to the other, increasing the threat of invasive species coming to the Arctic.

Marine Invasive Species get Bioblitzed in Ketchikan

2014-03-15

Non-native marine species are showing up along the Alaska coastline. While their numbers are small compared to California, where more than 200 marine invasive species are listed, there is reason for concern. So researchers who track the newcomers have enlisted volunteer reinforcements - the people who live along the coast to participate in a marine invasive species bioblitz.

ANB Harbor Replacement Moves Forward

2014-01-06

ANB Harbor is being decommissioned and rebuilt. In what may be the first time an invasive species has been considered in a decommission plan, the material from ANB harbor will be barged down to Seattle and disposed of on land. The wood will be taken to a landfill. The steel piling will be recycled. And officials hope the process will prevent the harbor’s invasive stow-aways from hitching a ride to any other Alaskan ports.

Bioblitz is an intensive survey in which trained volunteers head out en masse to catalog species in a specific area. On September 28, volunteers in Ketchikan, Alaska, joined staff from the Smithsonian Environmental Research Center (SERC), San Francisco State and the University of Alaska to search for invasive marine species along Ketchikan’s waterfront in an marine invasive species bioblitz.

Alien Invaders: invasive tunicates and shellfish aquaculture

2013-04-04

Several years ago, Washington State began tracking and eradicating invasive tunicates. Teams of scuba divers used ice scrapers and even blow- torches to remove tunicates at low tide, and divers removed a ton of them from just two marinas. SeaDoc supported Jeff Cordell and colleagues at the University of Washington to collect and analyze data on the impact of these tunicate species. Refreshingly, the research found little evidence that the three tunicate species of most concern are damaging our local ecosystem and our valuable shellfish industry. That’s great news for our local shellfish.
