Water Rate Hike due to Inasive Mussels

Southern California's largest water supplier is set to raise rates to offset higher electrical bills, protect endangered fish and pay for cleanup associated with an invasive mussel. Board members of the Los Angeles-based Metropolitan Water District are expected to approve what amounts to a 14.3 percent increase for its water in March, officials said.

New report on AIS threat to global marine biodiversity

Some 84 per cent of the world's marine ecosystems have been infected by invasive species - and this number could be even higher due to under-reporting, according to a new study from the Nature Conservancy. Although invasive species are widely recognized as a major threat to marine biodiversity, there has been no quantitative global assessment of their impacts and routes of introduction. The report gives initial results from the first such global assessment. Drawing from over 350 databases and other sources, it synthesizes information on 329 marine invasive species, including their distribution, impacts on biodiversity, and introduction pathways. Initial analyses show that only 16% of marine ecoregions have no reported marine invasions, and even that figure may be inflated due to under-reporting. International shipping, followed by aquaculture, represent the major means of introduction. The geographically referenced and publicly available database provides a framework that can be used to highlight the invasive taxa that are most threatening, as well as to prioritize the invasion pathways that pose the greatest threat.
