Abstract
Extensive phenotypic plasticity can allow populations to persist in changing environments. Maternal effects represent one important but often neglected source of phenotypic plasticity. Mothers and offspring of 2 high- (northern Norway and central Sweden) and 2 low- (northern and southern Spain) latitude yellow dung fly Scathophaga stercoraria (Diptera: Scathophagidae) populations were exposed to cold (12 degrees C) and warm (18 degrees C) temperatures and to short (8 h light: 16 h dark) and long (16 h light: 8 h dark) photoperiods in a fully blocked, split-brood common garden design of 8 treatment combinations. We also considered the role of energy content and s...
