Mean body size of female and male Mesocyclops edax at three temperatures from Douglas Lake, Michigan ( ) and Lake Thonotosassa, Florida (- -). Numbers and vertical lines refer to number of individuals and one standard error, respectively. Michigan locale, but FT females and males were larger than FF females and males, respectively (Table IV). Female and male body sizes were the only traits in this study that exhibited a significant genotype-environment interaction, as examined by two-way ANOVA (F2 139 , P < .001 for females; = , P < .001 for males) (Table V) and response curves (Fig. 2). Males were significantly smaller at 15°C than at 25°C in both MD (t(53 df) = , P < .001) and FT (t'( 115 df) = , P < .001) populations. Clutch size. FT individuals had larger clutch sizes than MD individuals at 15, 25, and 30°C (Fig. 3). Only one MD female of generation one produced a clutch at 15°C. This clutch had 19 eggs, which is typical for this population at all temperatures in the TABLE V ANOVA of adult body (nm) size in two populations (Douglas and Thonotosassa) o/Mesocyclops edax in three environments (15, 25 and 30°C) Females Source Source Population 1 2343000 <.001 Environment 2 3937000 <.001 Population X environment 2 1344000 <.001 Error 189 133000 Total 194 Males Population Environment Population X environment Error Total 1 2 2 135 140 220000 613000 680000 45000 <.05 <.001 <.001.
