This detachment could be promoted by environmental and biological phenomena, such as storms and grazers activity (e.g., Alves et al, 2001;García-Romero et al, 2023;Chebaane et al, 2023), and would explain the higher abundance of CCA on basalt, including Peyssonnelia sp., and the higher abundance of filamentous algae on concrete. Moreover, calcareous bio-concretions can also provide positive bio-protection effects, which may additionally protect the underlying substrate from deterioration (Coombes et al, 2017;Bone et al, 2022b;Lv et al, 2022).…”
