  • a Relative biovolumes are given as percentages, and the number in parentheses is the standard error.

  • b White mat 1 and white mat 2 were separated by 4 m, and white mat 2 and white mat 3 were separated by 5 m.

  • c This value is most likely overestimated due to relatively weak filament signal intensity and high background.
