As Australia officially enters winter, UniSA ecologists are urging coastal communities to embrace all that the season brings, including the sometimes-unwelcome deposits of brown seaweed that can accumulate on the southern shores.
While tidal seaweed (or sea wrack) may seem unsightly – especially at beach-side tourist destinations – new research from the University of South Australia shows that it plays a vital role for many migratory seabirds and should be protected.
In the first study of its kind, UniSA researchers show that beach-cast seaweed provides shelter, and a range of microclimates, in addition to food, that ensure the survival of many shore-bird species.
Specifically, sea wrack acts like a reverse-cycle air conditioner creating cooler conditions when the weather is hot and warmer conditions when it is cold, helping seabirds regulate their body temperatures.
