9432 Faxonius rusticus Environmental Water Quality 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. Ontonagon River, Michigan 14621
9433 Faxonius rusticus Environmental Water Quality 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. 25564
9434 Faxonius rusticus Environmental Water Quality Experimental Field Periphyton productivity showed an increase when F. rusticus is present, 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. Plum Lake, Vilas County, Wisconsin 14607
9435 Faxonius rusticus Environmental Water Quality Experimental Laboratory 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. 22839
9436 Faxonius rusticus Environmental Water Quality Experimental Laboratory Faxonius rusticus creates turbidity in its environment that results in an increase of harmful algae blooms by changing the water chemistry. 31205
9437 Faxonius rusticus Environmental Water Quality Observational Field Szydlowski et al (2022) found a weak, positive association between Faxonius rusticus abundance and water clarity. They hypothesize that lake clarity increases if F. rusticus causes declines in small fishes that lead to population growth and decreases in phytoplankton through a trophic cascade. Vilas County, Wisconsin 39998
