  • Detection and Quantification of an Ecologically Important Marine Pathogen, Paramoeba invadens 

    Buchwald, Robyn
    A pathogenic amoeba, Paramoeba invadens, causes re-current mass mortalities of sea urchins (Strongylocentrotus droebachiensis) in coastal Nova Scotia, with major ecological consequences for the structure of the rocky ...
  • Modelling phase shifts in a rocky subtidal ecosystem 

    Lauzon-Guay, Jean-Sebastien; Scheibling, Robert Eric; Barbeau, Myriam A. (Inter-Research, Nordbuente 23 Oldendorf/Luhe 21385 Germany, [], [URL:], 2008-03)
