Postzygotic Isolation Evolves before Prezygotic Isolation between Fresh and Saltwater Populations of the Rainwater Killifish, Lucania parva
Table 4
Analyses of L. goodei and L. parva survival in two fresh water chemistries (KH3 and KH8). Results of generalized linear model for (a) proportion of eggs hatched, (b) proportion of fry that survived to 14 days after hatch, (c) total survival (proportion of eggs that survived to 14 days after hatch). Statistically significant values are indicated in bold. Number of families per water treatment: IR KH3 = 6, KH8 = 6; Hybrid KH3 = 13, KH8 = 14; Pecos KH3 = 6, KH8 = 5; L. goodei KH3 = 5, KH8 = 7; total = 62. Number of eggs per water treatment: IR KH3 = 79, KH8 = 78; Hybrid KH3 = 94, KH8 = 86; Pecos KH3 = 68, KH8 = 60; L. goodei KH3 = 50, KH8 = 31. Number of fry per water treatment: IR KH3 = 21, KH8 = 21; Hybrid KH3 = 14, KH8 = 7; Pecos KH3 = 31, KH8 = 16; L. goodei KH3 = 45, KH8 = 13.
