Correlation Analysis of Adult Female, Egg and Hatchling Sizes in the Loggerhead Turtle, Caretta Caretta (L.), Nesting at Kiawah Island, South Carolina, USA
Abstract:Measurements of adult female, egg, and hatchling sizes were obtained for the loggerhead turtle, Caretta caretta, nesting at Kiawah Island, South Carolina, U.S.A., during the summers of 1982 and 1983. A 12 variable data matrix was analyzed to assess the degree of correlation between the different life history stages of this species. Total egg volume shows a higher correlation with mother size than clutch or egg size, suggesting that total egg volume is a good measure of reproductive allocation. Evidence is given for egg size optimization due to a “trade-off” between clutch size and hatchling size. Methods of determining hatch success are compared and the relation between incubation time and hatch success discussed.
