- W2015138833 abstract "Evidence from other species of sea urchins indicated that the growth rings found in the skeletal plates of Paracentrotus lividus (Lamarck) were probably formed annually, and could therefore be used as a means of determining age. In this species, annual formation of the rings has been proved by the similarity of growth curves derived from ring counts and size-frequency analyses; there is a good agreement between the annual increments predicted from these growth curves and those observed in experimental populations. Determinations of the cycles of ring deposition and reproduction gave results which were consistent with this interpretation. Similarities in the growth curves did not always extend to the mean values determined for each ring-class and the equivalent size-frequency groups, and the size-frequency distributions of single ring-classes were found to be much wider than those of the equivalent groups determined by sizefrequency analysis. This is attributed to a wide variation in the season of ring deposition in different individuals, and this limits the accuracy of ring count ageing to about ± one year. There were no significant differences between the reproductive cycles of male and female urchins; the gonad indices rose to peak values in late winter and late summer. Gonad condition was very variable within each population sample. The animals grew to a mean diameter of 35–50 mm in about four years, after which growth rates slowed down, and it is probable that most of the urchins died of senescence after 6–9 years." @default.
