Fig. 1. Pectoral muscle enzyme activities (µmol min1
g1 lean muscle mass) versus percent body fat in
semipalmated sandpipers refueling in the Bay of Fundy. CS, citrate synthase
(N=38 animals); CPT, carnitine palmitoyl transferase (N=39);
HOAD, 3-hydroxyacyl dehydrogenase (N=37); LDH, lactate dehydrogenase
(N=39). Lines were fitted by linear regression (CS:
y=455.93+3.56x; HOAD: y=72.29+0.79x).
*P<0.05; NS, not significant.
