      Riesgo, Ana; Taboada, Sergi; Pérez-Portela, Rocío; Melis, Paolo; Xavier, Joana R.; Blasco, Gema; Lopez-Legentil, Susanna (Peer reviewed; Journal article, 2019-01-16)
      Background: Knowledge about the distribution of the genetic variation of marine species is fundamental to address species conservation and management strategies, especially in scenarios with mass mortalities. In the ...
    • Glass sponge grounds on the Scotian Shelf and their associated biodiversity 

      Hawkes, Nickolas James; Korabik, Michelle; Beazley, Lindsay; Rapp, Hans Tore; Xavier, Joana R.; Kenchington, Ellen (Peer reviewed; Journal article, 2019)
      Emerald Basin on the Scotian Shelf off Nova Scotia, Canada, is home to a globally unique population of the glass sponge Vazella pourtalesi. Through the analysis of both in situ photographs and trawl catch data from annual ...
