| Impact Description | Contest experiments between the yabby (Cherax destructor), signal crayfish (Pacifastacus leniusculus), and marbled crayfish (Procambarus virginalis) suggest the signal crayfish is the most aggressive and competitively dominant of the three species. The yabby was more aggressive and won more contests than the marbled crayfish, indicating a high probability of competitive dominance in areas where they co-occur. |
