LT = Lake Tarawera, UT = upstream Tarawera, DT = downstream Tarawera, RR = Rangitaiki River, KR = Kaituna River. N_M = Samples included in meristic analyses, N_O = Samples included in otolith analyses, %_ND = Percentage of non-diadromous fish, N_R = Female samples included in reproduction-type comparisons, %_S = Percentage of summer spawning females, Stat. = Significant differences (P < 0.05) in spawning type composition, shared letters indicate no significant difference at P < 0.05. N_G = Samples included in genetic analyses, %_P = Percentage polymorphic fragments (from 732 total fragments), H_SW = Shannon-Wiener Diversity index.
