Experimental
|
Field
|
Periphyton productivity showed a 4 to 7 fold increase in enclosures where Faxonius rusticus were present, likely due to the indirect effect of reduced macroinvertebrate grazer densities and the direct effect of the reduction of non-photosynthetic portions of the periphyton matrix.

Observational
|
Field
|
Faxonius rusticus promotes periphyton productivity and algal blooms in invaded areas. The algal blooms are likely the result of the crayfish being a much less efficient grazer than the macroinvertebrates it replaces.

Faxonius rusticus have an indirect positive effect on periphyton through the reduction of snail abundance. The resulting algal blooms in invaded areas are likely the result of F. rusticus being a much less efficient grazer than the macroinvertebrates it replaces.
