Kelps are highly productive seaweeds predominantly found in wave-exposed environments. Physical and biological processes such as sand abrasion, whiplash and grazing can wound kelp tissue, potentially weakening its ability to withstand wave forces. Despite the ecological importance of kelp tissue loss, few studies have quantified wounding patterns in kelps or how wounding might affect the biomechanical properties of kelps. We quantified the prevalence of wounds on 360 Ecklonia radiata kelps collected across 3 different reef lines (levels of wave exposure) in April (autumn), June (early winter), August (winter) and October (early spring) (i.e. before, during and after peak wave activity). …
