Ulva intestinalis is amongst the first multicellular algae to appear on substrata that have been cleared following a disturbance, e.g. Isle of Man historical wildlife records 1995 to 1999.

Royal Botanic Garden Edinburgh Herbarium (E). Fife Nature Records Centre, 2018. & Marsland, A., 1976. Epibionts like Ulva can also exert increased drag on snails living in high flow conditions, causing them to invest more energy in foot muscles and less in growth (Wahl 1996).
