Figure 4. Proportion of behavioral allocation of competing C. sapidus and C. maenas during interspecific interactions when the C. sapidus individual was either unexposed or boat noise-exposed.

The behavioral allocation proportion of dominant, neutral, and submissive behaviors are shown for the C. sapidus/C. maenas interaction. The C. sapidus individuals (upper two panels) in the interaction were either unexposed to noise or exposed to boat noise, while the C. maenas were all unexposed (lower two panels). The proportion of behavioral allocation is depicted for: (A) unexposed C. sapidus in competition with unexposed C. maenas (N = 34); (B) boat noise-exposed C. sapidus in competition with unexposed C. maenas (N = 23); (C) unexposed C. maenas in competition with unexposed C. sapidus (N = 34); and (D) unexposed C. maenas in competition with boat noise-exposed C. sapidus (N = 23).
