“…Hence, only a proper re-analysis of the shells used in the previous studies will show whether we are dealing with an increase of maximum lifespan with decreasing ambient temperature, as observed in other bivalve species (e.g. Lomovasky et al, 2008Lomovasky et al, , 2011, or with a distinct underestimation of individual age in the previous studies. Although the difference between our analysis and those previously reported may lead to the hypothesis of changes in growth rate, we believe that it is most likely due to deficiencies of the used techniques.…”

“…Las tasas de crecimiento, así como también el peso total del individuo, el peso de sus partes blandas, el peso de músculo y el peso de la góna-da varían estacional (Valero 2002;Lomovasky et al 2007) y latitudinalmente (Defeo y Gutiérrez 2003;Lomovasky et al 2008). Sin embargo, este patrón de crecimiento entre las diferentes partes del individuo no es completamente sincrónico (Lomovasky et al 2008).…”

Sin embargo, este patrón de crecimiento entre las diferentes partes del individuo no es completamente sincrónico (Lomovasky et al 2008). Para la UM B (ex Banco Reclutas, 39° S-39° 30' S; 55° 21' W-56°3 0' W) las tasas máximas de crecimiento de valva se registraron durante los meses de invierno, mientras que las tasas máximas de crecimiento en músculo fueron en primavera y en gónada en otoño hasta la transición de invierno (Valero 2002;Campodónico et al 2008;Lomovasky et al 2008).…”

“…Most growth studies of Z. patagonica were based on observations of external growth rings (Defeo and Gutiérrez, 2003;Gutiérrez and Defeo, 2005;Lasta et al, 2001;Waloszek and Waloszek, 1986). These results show substantial discrepancies on the estimates of maximum age when compared with estimations based on analysis of internal structures such as chondrophores and ligaments (Bizikov and Middleton, 2002;Lomovasky et al, 2007Lomovasky et al, , 2008. This discrepancy may in part be due to the poor readability of external rings as individuals get older (see Bizikov and Middleton, 2002;Lomovasky et al, 2007Lomovasky et al, , 2008.…”
