Fig. 8 in Morphological requirements in limulid and decapod gills: A case study in deducing the function of lamellipedian exopod lamellae

Fig. 8. Body−weight specific lamellar numbers and average single lamellar area in bi−logarithmic coefficients. A. Bi−logarithmic graph of total number of lamellae with respect to dry−body weight in Limulus polyphemus (close circle), Tachypleus rotundicauda (open circle), Callinectes sapidus (solid square) and Libinia dubia (open square). B. Results of allometric analysis shown in Fig. 5A. Sample size (N), correlation coefficient (r), reduced major axis of logW = αlogNL + logβ, and K = α – α / [(s)2 + (s)2]1/2 where s is the standard deviation of α. K is a statistic with the standard normal distribution used for 1 2 α1 α2 α discrimination of the differences of α significant or not. If K>1.96 or K <−1.96, the difference is significant. See also Fig. 7 for the abbreviations of W and NL. C. Bi−logarithmic graph of average area per lamella with respect to dry−body weight. Abbreviations as in Fig. 5A. D. Results of allometric analysis shown in Fig. 5C. Same abbreviations as in Fig. 5B. The data of two decapods are referred to Hughes (1983), which presented average, maximum and minimum specific dry−body weight and lamellar number among the examined samples as well as α and logβ of the allometric analysis with respect to their dry−body weight. Readers are referred to the results of T. rotundicauda as reference data, because too small numbers have been examined. This is to show the trend that the results of a species fall in a neighboring area to that of a taxonomically close species.
