1925 Faxonius rusticus Genetic Observational Field Faxonius rusticus hydridizes with Faxonius propinquus in its native range, produce offspring and changing the genetic makeup of the native species, which is ecologically different from F. rusticus; male F. rusticus also outcompete native males for native mates. 13217
1926 Faxonius rusticus Genetic Observational Field Faxonius rusticus displaces Faxonius propinquus in its native range through hybridization. Genetic hybridization has been observed in locations spanning most of the eastern shoreline of Lake Michigan, with F. rusticus males able to outcompete F. propinquus males for F. propinquus females. Hybrids are competitively superior and ultimately excludes genetically pure F. propinquus faster than F. rusticus could directly. 23025
9427 Faxonius rusticus Genetic Experimental Laboratory Faxonius rusticus can hybridize with F. propinquus. 27353
9428 Faxonius rusticus Genetic Observational Field In a 1980 study, over 25% of the crayfish individuals collected from several northern Wisconsin lakes showed characteristics of hybridization between Faxonius rusticus and F. propinquus. Vilas County, Wisconsin 25541
9429 Faxonius rusticus Genetic Anecdotal N/A Faxonius rusticus can hybridize with F. propinquus. 14628
9430 Faxonius rusticus Genetic Observational Field Faxonius rusticus can hybridize with F. propinquus. About 25% of the crayfish collected from lakes in northern Wisconsin showed genetic evidence of hybridization between F. rusticus and F. propinquus. This results in competitive superiority of the hybrids and ultimately excludes genetically pure F. propinquus faster than F. rusticus could directly. Midwest Region, US 14758
9431 Faxonius rusticus Genetic Observational Field Genetic analysis of crayfish in Pennsylvania provide evidence for hybridization between Faxonius rusticus and F. obscurus. Juniata River system, Pennsylvania, USA 40025
