6622 Procambarus virginalis Competition Observational Field Procambarus virginalis pose a threat to indigenous crayfish species in Madagascar due to competition for food, habitat, and crayfish plague transmission. Madagascar 31149
6623 Procambarus virginalis Competition Observational Field Current data suggests that the Procambarus virginalis is a fast-growing species that exhibits r-selected life history traits like early maturation, an extended breeding period, and high fecundity, giving it a competitive advantage over other species. Germany 31142
7163 Procambarus virginalis Competition Anecdotal N/A Procambarus virginalis can form populations capable of self-reproduction in the presence of only one individual competing with native species in the Ukraine. Ukraine 42144
7165 Procambarus virginalis Competition Observational Field Procambarus virginalis in Madagascar waters threaten the extinction of seven endemic species of crustaceans. Madagascar, Africa 42144
9277 Procambarus virginalis Competition Experimental Laboratory Results of a competition experiment suggests that marbled crayfish Procambarus virginalis dominates in interactions with red swamp crayfish P. clarkii. Marbled crayfish won significantly more fights and established dominance more frequently in both mature and premature trials. 39235
9278 Procambarus virginalis Competition Anecdotal N/A Results of a dynamic energy budget model suggest that marbled crayfish is a superior competitor when considering metabolism and ontogeny. Models show that marbled crayfish has a clear potential to be a better competitor than Astacus astacus, Austropotamobius torrentium, and Pacifastacus leniusculus. 40058
9279 Procambarus virginalis Competition Observational Field Analysis of three co-existing crayfish populations suggests that the marbled crayfish (Procambarus virginalis) and spinycheek crayfish (Faxonius limosus) trophic niches overlap, indicative of competition. Results also indicate likely competition for food with the red swamp crayfish (P. clarkii). River Danube, Hungary 40079
9280 Procambarus virginalis Competition Experimental Laboratory Experimental studies were conducted to examine agonistic interactions between signal crayfish (Pacifastacus leniusculus), common yabby (Cherax destructor), and marbled crayfish (Procambarus virginalis). The marbled crayfish was the least aggressive and least successful in agonistic interactions. However, other factors such as growth rate and reproductive potential may alter competitive interactions in favor of marbled crayfish. 41109
9281 Procambarus virginalis Competition Anecdotal N/A Environmental niche and species distribution modeling suggest a high degree of niche overlap and high risk of co-occurence between the marbled crayfish (Procambarus virginalis) and freshwater crab species in Southeast Asia. Southeast Asia 41131
9282 Procambarus virginalis Competition Experimental Laboratory Marbled crayfish has shown competitive dominance over calico crayfish (Faxonius immunis) in experimental lab studies. When no shelter was available, marbled crayfish won significantly more fights. With available shelter, marbled crayfish dominance was 100% for female and 54.5% for male calico crayfish. 41961
9285 Procambarus virginalis Competition Experimental Laboratory Competition experiments suggest that marbled crayfish (Procambarus virginalis) are more aggressive and more active competitors than spinycheek crayfish (Faxonius limosus). 41965
9286 Procambarus virginalis Competition Experimental Laboratory Marbled crayfish (Procambarus virginalis) and round goby (Neogobius melanostomus) are expected to compete for shelter in areas where they co-occur. Competition is expected to be strongest during the daylight hours. 41972
