Abstract
The development of a population of Eudiaptomus vulgaris (Schmeil, 1896) in the Meeuwenven, a shallow acid guanotrofic moorland pool, has been described during one year. The population hibernates as copepodite 5 stages, adults and, to a small extent as naupliar stages N1, N2 and N3 (which could not develop further at low temperatures in autumn). In spring the population development starts at temperatures above 10°C and shows 3 or 4 pulses a year. An attempt has been made to explain seasonal changes in the size of adult males and females and in the sex ratio.
In order to establish the duration of the various development stages, the animals have been cultured at different temperatures under illumination with 2000 Lux at a daylength of 14 hours. An adequate quantity of food from the natural habitat was available.
Total egg development and total naupliar and copepodite development have been compared with the results of other workers, especially with those from Eckstein (1964), who studied Eudiaptomus vulgaris in the deep Schluchsee. The duration curves do not differ markedly with those of Eckstein and are strongly temperature dependent.
The relation between the development times of the various stages with temperature can be generally expressed as parabolic regressions of the type D = a + b1T + b2T2, the C5 and adult stages being the only exception at higher temperatures. Comparison of the relative duration of the stages at different temperatures did show that younger stages can take a larger share of the total development time at lower temperatures, stage N6 being the most temperature-sensitive.
