Effect of hydro-climate variation on biofilm dynamics and its impact in intertidal environments (2022)
Journal Article
Bastianon, E., Hope, J. A., Dorrell, R. M., & Parsons, D. R. (2022). Effect of hydro-climate variation on biofilm dynamics and its impact in intertidal environments. Earth surface dynamics European Geosciences Union, 10(6), 1115-1140. https://doi.org/10.5194/esurf-10-1115-2022

Shallow tidal environments are very productive ecosystems but are sensitive to environmental changes and sea level rise. Bio-morphodynamic control of these environments is therefore a crucial consideration; however, the effect of small-scale biologic...
