Distinct migratory and non-migratory ecotypes of an endemic New Zealand eleotrid (Gobiomorphus cotidianus) – implications for incipient speciation in island freshwater fish species

Table 2 Morphotypes in each sample site.

Site	N _M	Type 1	Type 2	Type 3	Stat.

LT = Lake Tarawera, UT = upstream Tarawera, DT = downstream Tarawera, RR = Rangitaiki River, KR = Kaituna River. N_M = Number of individuals per sample site included in meristic analyses. Type 1, 2 and 3 = proportion of the respective morphotype (Figure 2) in sample site. Stat. = Significant differences in morphotype compositions between sample sites, shared letters indicate no significant difference at P < 0.05.
