Figure 5. Changes in modeled dominant competitive behaviors of unexposed and noise-exposed blue crabs (C. sapidus) and paired unexposed green crabs (C. maenas).

Dominant behaviors were modeled using a Bayesian Linear Mixed Model to determine the effects of and submissive competitive interactions are shown for how unexposed (Control) and boat noise-exposed (Exposed) C. sapidus behaved against conspecific competitors or heterospecific competitor (C. maenas) crabs. (A) Overall dominant behaviors modeled by time spent: changes in modeled time spent (seconds) to overall dominant behaviors in the unexposed C. maenas paired with unexposed and boat noise-exposed C. sapidus are depicted in the upper two quadrants, and changes in modeled time spent (seconds) to overall dominant behaviors in the unexposed and boat noise-exposed C. sapidus paired with unexposed C. maenas are depicted in the lower two quadrants. (B) Overall food behaviors modeled by time spent. Depicted in the same manner as (A).
