Directional and stabilizing selection for developmental time and correlated response in reproductive fitness in Tribolium castaneum

Abstract: Directional and stabilizing selection for developmental time (DT) were done for seven generations in replicated lines of Tribolium castaneum. There were no significant differences between sexes or among replicates in means or coefficients of variation. For directional selection, there were significant responses in both directions, measured as deviation from control, viz. -0.35±0.15 day per generation for Fast (F) and 0.73±0.15 day for Slow (S). The unselected control (C) and the stabilizing selection (I) lines… Show more

“…Though rgs consistent with the operation of trade-offs have sometimes been found in other studies (e.g. Holloway et al, 1990; Rose & Charlesworth, 1981;Soliman, 1982), this is not always so (e.g. Stearns, 1983;Murphy eta!., 11983;Bell, 1984a,b;Holloway eta!., 1993b).…”

“…Numerous studies in T. castaneum show that experimental selection for almost any trait occurs within a few generations (e.g. Soliman 1982;Cardin & Minvielle 1986) while mutation can rapidly add substantial genetic variance (Enfield & Braskerud 1989). These studies are based on fewer than our 10 replicate lines, making it unlikely that our results only reflect random fluctuation (genetic drift).…”

“…Some have successfully demonstrated the predicted genetic structure (e.g. Simmons et a!., 1980;Rose & Charlesworth, 1981;Soliman, 1982;Luckinbill et a!., 1984;MØller et a!., 1989;Holloway et a!., 1990a), but at least as many studies have not (e.g. Giesel & Zettler, 1980;Giesel et a!., 1982;Murphy et a!., 1983;Stearns, 1983;Bell, 1984a,b).…”
