“…However, we do not observe this pattern in tag recovery. Lamare & Mladenov (2000) observed a 37% tag recovery rate after 1 yr and a 30% recovery rate after 4 yr at a mid-fjord site. Dispersion studies of Evechinus chloroticus confirm that although movement rates can vary with food availability, there is no evidence for consistent directional movement of adults (Andrew & Stocker 1986).…”

“…1 mo (Dix 1970a, Walker 1984, Lamare & Barker 1999. Following settlement, juveniles grow at a rate of 10 to 15 mm yr -1 , becoming reproductively mature at a size of approximately 30 to 50 mm test diameter (Dix 1970b, Lamare & Mladenov 2000. Larval dispersal is high in most populations and is reflected in the lack of genetic differentiation in E. chloroticus along the New Zealand coast.…”

“…For the effectiveness of the best model RMS should be lowest, R 2 and Adjusted R 2 should be highest, expected value of Mallow's C p statistic should be equal to the number of parameters in the model and asymptotic correlation coefficients should be high (absolute value higher than 0.95); then there will be no suspicions about the precision of the parameters in each model (Gage and Tyler, 1985;Cellario and Fenaux, 1990;Neter et al, 1990;Draper and Smith, 1998;Lamare and Mladenov, 2000).…”

This study aimed to determine the growth of 26 Akkeci (White goat = Saanen × Kilis (Bı) crossbreed) female kids by measuring their body weight, withers height, body length, heart girth depth, heart girth width, heart girth circumference, leg circumference and volume index in two-week intervals from birth to 500 days of age and by using different growth models (Monomolecular, Gompertz, Weibull and Richards). An approximate volume index was calculated by multiplying the values of heart girth depth, body length and heart girth width. The best one among these models was determined in respect of RMS (square root of Residual Means Squares which is calculated from the Square Root of Error Mean Square in ANOVA), R 2 %, Adjusted R 2 %, Mallow's C p statistic, and asymptotic correlation coefficients criteria. As a result, it was determined that Weibull growth model (which is not concerned with Weibull statistical distribution but is related to parameters of Weibull distribution) was suitable for the above-mentioned material and studied traits.

“…These problems can be alleviated by the use of a permanent internal shell marker, as long as the protocol used can be shown not to affect the growth measurement. Recent studies have suggested that the non-toxic calcium marker calcein may be such a suitable marker (Medeirosbergen and Ebert 1995;Stewart 1996;Moran 2000;Lamare and Mladenov 2000).…”

Growth in the limpet Nacella concinna from contrasting sites in Antarctica

et al. 2004

Annual shell growth was determined by mark and recapture in the limpet Nacella concinna (Strebel 1908) at two contrasting sites in Antarctica. At Signy Island, 60°S, growth was moderately fast, comparable with some limpets in more temperate areas. The fluorescent calcium marker calcein was used to validate the results from the mark/recapture study, and fine-scale growth increments showed that shell growth was seasonal. Further south at Rothera Point, 67°S, mean annual growth over a 3-year period was significantly slower than at Signy, and in 1 year was the slowest yet reported for a limpet. Comparison with an earlier mark/ recapture study at Arthur Harbour, Palmer Station (64°S) revealed a cline of decreasing growth performance with increasing latitude along the Antarctic Peninsula. It is not clear whether the slower annual growth rate at higher latitude was caused by physiological constraints, a reduced length of growing season, or a combination of both. Limpets show a global cline in growth performance, which decreases towards higher latitudes.
