| Description: | Quantitative expressions are presented describing the effects of temperature and food concentration on the mean body weight of copepodite stages of <i>Pseudocalanus</i> spp. The calculations were made on the basis of experimental data from the literature for three geographically separate populations of <i>Pseudocalanus</i> from Puget Sound (Washington, USA), from the southern North Sea and the Baltic Sea. Relationships were obtained between the coefficient of daily exponential growth of body weight of <i>Pseudocalanus</i> sp. from Puget Sound and temperature in the 8-15.5<sup>o</sup>C range and food concentrations from 10 mgC m<sup>-3</sup> to excess, as well as for <i>Pseudocalanus elongatus</i> from the southern North Sea at high food concentrations and in the 4-15<sup>o</sup>C temperature range. Also computed was the mean body weight for stages CII to CV of <i>P. elongatus</i> from the southern Baltic Sea at 5<sup>o</sup>C. The empirical models presented here can be used with good precision in mathematical models of pelagic communities. The results presented here indicate that <i>Pseudocalanus</i> sp. from Puget Sound (a species resembling <i>Pseudocalanus minutus</i>) is similar to <i>P. elongatus</i> from the southern North Sea and the English Channel with respect to growth parameters in the studied range of temperatures for excess food. <i>P. elongatus</i> collected in the Baltic Sea (Gulf of Gdańsk) differs from <i>P. elongatus</i> from the southern North Sea. |
