Responses to heterospecific chemical cues may arise by one of two non-exclusive mechanisms (Mitchell et al., 2012; Schoeppner and Relyea, 2009): (1) individuals may possess an innate recognition of alarm cues common to closely related species (the ‘phylogenetic relatedness hypothesis’) and/or (2) individuals may acquire recognition of relevant alarm cues through experience (the ‘ecological coexistence … temperature, salinity, hypoxia), comparatively long breeding seasons and high fecundity.
