International scientific team criticizes adoption of ‘novel ecosystems’ by policymakers

This picture features a classic novel ecosystem. The ground cover is cogon grass, a highly invasive Asian grass that is one of the South’s worst and fastest-growing weed problems. The trees in this forest are most native loblolly pine. The picture was taken recently on the flood plain of the Pascagoula River in Mississippi. Credit: [...]

Project serves up big data to guide managing America’s coastal waters

Project serves up big data to guide managing America’s coastal waters

When it comes to understanding America’s coastal fisheries, anecdotes are gripping — stories of a choking algae bloom, or a bay’s struggle with commercial development. But when it comes to taking action, there’s no beating big data. In this week’s edition of Estuaries and Coasts, a Michigan State University doctoral student joins with others to [...]

Viruses take down massive algal blooms, with big implications for climate

This is a location map. Black rectangle delineates the area shown in Figures 1B and 2. (B) Map of surface chlorophyll from June 22, 2012 (day 174), emphasizing the phytoplankton patch as a distinct area of high chlorophyll concentration. Thick black lines mark the main attracting Lagrangian coherent structures from calculation of finite-size Lyapunov exponents. [...]

Ibuprofen posing potential threat to fish, researchers say

Ibuprofen posing potential threat to fish, researchers say

Research led by the University of York suggests that many rivers contain levels of ibuprofen that could be adversely affecting fish health. Using a new modelling approach, the researchers estimated the levels of 12 pharmaceutical compounds in rivers across the UK. They found that while most of the compounds were likely to cause only a [...]

Porci mistreti radioactivi, la aproape 3 decenii de la dezastrul nuclear de la Cernobal

Porci mistreti radioactivi, la aproape 3 decenii de la dezastrul nuclear de la Cernobal

  Dupa aproape trei decenii de la dezastrul nuclear de la Cernobal, unul din trei porci mistreti din Germania este prea radioactiv pentru a putea fi mancat de catre oameni, potrivit unor studii. Oficialii din Saxonia (un land situat in estul Germaniei) au testat 752 de porci mistreti incepand cu 2012 si au gasit 297 [...]
