Summary of seasonal T₀ values for studied biomarkers in each locality.

LP (min); VvL (μm3/μm3); SvL (μm2/μm3); S/VL (μm2/μm3); NvL (1/μm3); VvNL (μm3/μm3); VvBAS (μm3/μm3); MET (μm); MLR (μm); MLR/MET (μm/μm); CTD ratio; TAOC (Teq μmol); PK (U/g prot); PEPCK (U/g prot); COX (U/g prot); HK (U/g prot); GP (U/g prot); GI; PSSF (%); and POA (%). Background levels: LP>20 [23–25,35,49–51]; VvL(fall,summer)<0.002 and VvL(spring)<0.0005 [22–25,35,50,51]; SvL<0.009 [22–25,35,50,51]; S/VL>4 [22–25,35,50,51]; NvL(winter)<0.004 and NvL(summer)<0.002 [22–25,35,50,51]; VvNL(spring, summer)<0.005 and VvNL(fall)<0.1 [51,52]; VvBAS<0.12 [26,35,51]; MLR/MET(fall, summer)<1.2 and MLR/MET(spring)<0.6 [26,35,51]. Different letters (a, b, c) indicate significant differences between seasons in mussels from each locality. Characters in bold indicate significant differences between localities for a given season after either Man Whitney’s U-test or Student’s t-test (p<0.05) (or χ2 for PSSF and POA). UDL: Under detection limit; PSSF: prevalence (%) of small sized mature follicles; POA: prevalence (%) of oocyte atresia.
