↑ = increased expression relative to control; ↓ = decreased expression to control; - = no change from control; n.d. = not determined

DOM = dominant; SUB = subordinate (subgrouping not specified or identified); NRS = non-responsive subordinate; SRS = stress = responsive subordinate; OM = Omega grouping (Melhorn et al, [16]).
