“…All around the world canopy‐forming kelp and fucoid species are being impacted by warming waters (e.g. Australia: Phillips & Blackshaw, , Smale & Wernberg, , Japan: Tanaka, Taino, Haraguchi, Prendergast, & Hiraoka, , Mediterranean: Thibaut, Blanfune, Boudouresque, & Verlaque, ) and further massive changes to the distribution and composition of coastal seaweed communities are expected (Martinez et al, ; Wilson, Skinner, & Lotze, ). Along the Atlantic coast of South America, warming of western boundary currents and their extensions such as the Brazilian current (+1.93°C per century between 1950 and 2008) have been associated with greater poleward penetration of warm water (Wu et al, ).…”
