Fig. 3. Temperature-dependent protein synthesis capacities in lysates prepared from white muscle (A,C) and gills (B,D) of P. brachycephalum (A,B) and Z. viviparus (C,D) acclimated to various temperatures. Closed circles: control P. brachycephalum maintained at 0°C; open circles: warm-acclimated P. brachycephalum (5°C); closed squares: control Z. viviparus maintained at 10°C; open squares: cold-acclimated Z. viviparus (5°C). Values are means ± S.E.M. (control and warm-acclimated P. brachycephalum N=5; control Z. viviparus N=3; cold-acclimated Z. viviparus N=4).
