(UNITED KINGDOM, 8/25/2016)
New research exploring the impact of rising temperatures coupled with the presence of tritium on marine mussels (Mytilusgalloprovincialis) concluded that increased sea temperatures could dramatically enhance and accelerate radiation-induced DNA effects in marine invertebrates.
The study, led by Plymouth University in conjunction with the Centre for Environment, Fisheries and Aquaculture Science (Cefas), demonstrated that at radiation dose rates considerably below the recommended international guidelines, induced DNA strand breaks appeared earlier at higher temperature compared to lower temperature.
The research revealed that at 15 ºC, DNA damage was only significantly elevated after seven days in contrast to 25 °C where a similar response was observed after three days.
Scientists involved say this suggests an acceleration of radiation-in...
Commercial disasters declared for nine West Coast fisheries United Nations
The Commerce Secretariat determined that nine salmon and crab fisheries in Alaska, California and Washington experienced commercial failures, which will enable fishing communities to seek disaster relief assistance from Congress.
ICES identifies 'substantial' species distribution shifts Denmark
A total of 16 out of 21 species examined by experts of the Workshop on Fish Distribution Shifts in response to a request from the EC have shown changes in their distributions across the northeast Atlantic since 1985, with hake and mackerel shifting the most.
