| Impact Description | 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. |
