Influence of environment and mineralogy on euendolithic microboring patterns
Field experiments at Little Ambergris Cay reveal that euendolithic microorganisms preferentially bore carbonate substrates based on mineralogy, sea water saturation and trace metal content. Results highlight night‐time dissolution activity and mineralogical preferences, shedding light on the ecological and evolutionary drivers of bioerosion and their ...
