1896 Faxonius rusticus Habitat Alteration Anecdotal N/A Anecdotal observations attribute the introduction of F. rusticus to the declines in macrophytes in much of northern Wisconsin lakes, which is thought to have had a trophic cascade amoung the food web, in which now fish populations are reduced. 25542
1898 Faxonius rusticus Habitat Alteration Experimental Laboratory Faxonius rusticus reduces macrophyte diversity through selective macrophyte destruction, which futher changes the local environment richness and ecological assemblage. 14834
1899 Faxonius rusticus Habitat Alteration Observational Field The presence of F. rusticus has been show to result in a lower species richness, abundace, and within-site distribution of native crayfish in some areas of its introduced range. 30926
1900 Faxonius rusticus Habitat Alteration Experimental Laboratory Crayfish in general are considered to be ecosystem engineers, as they have a wide variety of indirect effects on ecosystems through disturbances. Faxonius rusticus creates turbidity in its environment that results in an increase of harmful algae blooms by changing the water chemistry. 31205
1903 Faxonius rusticus Habitat Alteration Experimental Laboratory The consumption of periphyton by the rusty crayfish outside its native range has been shown to create a trophic cascade that impacts many trophic levels, organisms, and ecological interactions. 14607
7713 Faxonius rusticus Habitat Alteration Anecdotal N/A crayfish diminish habitat complexity through vegetation reduction, re-suspension of sediment, and bioturbation 42165
9438 Faxonius rusticus Habitat Alteration Experimental Field Crayfish, in general, are considered ecosystem engineers that influence ecosystems through disturbances. Results of a field experiment in Maryland suggest crayfish influence the detritus processing regime and distribution of fine particulate matter in headwater streams. Clifford Hollow Branch of Tuscarora Creek, Maryland 25545
9439 Faxonius rusticus Habitat Alteration Anecdotal N/A Crayfish in general are considered to be ecosystem engineers, as they have a wide variety of indirect effects on ecosystems through disturbances, such as bioturbation. 17653
9440 Faxonius rusticus Habitat Alteration Experimental Laboratory Crayfish in general are considered to be ecosystem engineers, as they have a wide variety of indirect effects on ecosystems through disturbances. Results of an experimental stream study suggest crayfish behavior significantly influences sand and gravel erosion. 27346
9441 Faxonius rusticus Habitat Alteration Experimental Field Crayfish in general are considered to be ecosystem engineers, as they have a wide variety of indirect effects on ecosystems through disturbances, such as bioturbation. Results of a 50 day experiment suggest crayfish alter bank structure through the removal of fine sediment. New Zealand 27349
9442 Faxonius rusticus Habitat Alteration Experimental Field Crayfish in general are considered to be ecosystem engineers, as they have a wide variety of indirect effects on ecosystems through disturbances. A field experiment in Canada found that crayfish, through an engineering role, alter detritus decomposition rates, reduce the abundance of particulate organic matter, and diminish leaf pack diversity. East Creek, BC, Canada 27351
