    Commercial capture fisheries produce huge quantities of offal, as well as undersized and unwanted catch in the form of discards. Declines in global catches and legislation to ban discarding will significantly reduce discards, ...
  • Birds Reveal their Personality when Singing 

    Garamszegi, László Zsolt; Eens, Marcel; Török, János; Tregenza, Tom (Public Library of Science, 2008-07-09)
    Background Individual differences in social behaviour may have consequences for mate choice and sexual signalling, because partners should develop preferences for personalities that maximize reproductive output. Here ...
