Genetic differentiation (FST), difference in centroid location of stable isotope ratios of carbon and nitrogen (SI), and diet similarity (Diet) between fish from the two habitats. Stomach contents (%) were divided into profundal (Prof), littoral (Lit), and pelagic (Pel) prey items, and the most important prey group is in boldface.
Based on 16 neutral microsatellite loci. All comparisons were statistically significant (P < 0.05).
All comparisons were statistically significant (P ≤ 0.001).
Schoeners index based on stomach contents. Values >0.6 are generally interpreted as biologically significant similarities.
Mean number of gill rakers. All comparisons were statistically significant (P ≤ 0.01).
