“…Founder effects and genetic drift are clearly influential on genetic differentiation of neutral genes, and this has been documented for several fish populations (Merritt et al, 1977;Jorde, 1995;Carvalho et al, 1996;Fox et al, 1997). However, these mechanisms will also influence fitness-related genes, and weaken the efficiency of selection in the populations with frequent drift episodes (Kirkpatrick, 1996).…”

Among eight populations of grayling Thymallus thymallus that shared common ancestors 8-28 generations earlier, mean egg mortality ranged between 1·2 and 59·8%; mortality during yolk sac absorption was low (0·0-8·0%) and mean survival to swim-up was high (90-97%), with two exceptions (20% and 50%). Survival probabilities differed significantly among populations, even after statistically adjusting for size at swim-up and water depth, water velocity, gravel size and temperature. Development time from fertilization to first observed swim-up was significantly different among populations, ranging between 27 to 40 days, or 264 to 280 degree-days. Mean specific growth rates during the first external feeding period varied between 1·2 and 2·0% day 1 among populations. Population-specific growth rates were independent of temperature. Rates of divergence were of the same order as in other salmonid studies showing rapid evolution. The phenotypic differences may be due partly to genetic differentiation among the populations. 2000 The Fisheries Society of the British Isles

The interspecies homology of dace supernatant (A2,AB,B2) and mitochondrial (C2) malate dehydrogenase isozymes has been established through cell fractionation and tissue distribution studies. Isolated supernatant malate dehydrogenase (s-MDH) isozymes show significant differences in Michaelis constants for oxaloacetate and in pH optima. Shifts in s-MDH isozyme pH optima with temperature may result in immediate compensation for increase in ectotherm body pH with decrease in temperature, but duplicate s-MDH isozymes are probably maintained through selection for tissue specific regulation of metabolism.
