Interplay between environmental and organismic contingencies in the shaping the caviomorph AOB. We suggest that the opposite patterns of AOB heterogeneities found in capybaras (caudal-biased) and Octodon degus (rostrally biased) may reflect contextual differences in their habitat (humid vs. arid), their scent-marking strategies (non-volatiles vs. volatiles) and/or the social context in which semiochemical communication occurs (intra-males vs. male–female).
