Periphyton biomass spatial patterns and species abundances

Images of periphyton's biomass colonization in artificial substrata. The experiment was described in [1] but these images were not analyzed in the paper and not included in the data uploaded to dryad [2]. The original hypothesis was that the growth of microalgae in artificial substrata have a two dimensional multifractal structure. I include measurements of environmental variables and nutrients not analyzed in the paper. We used this software: https://github.com/lsaravia/tiff2biom https://github.com/lsaravia/mfsba References 1.
