A complete description of our studies on the population dynamics of Gyrinus marinus Gyll is given below. The study has been started in 1966 and is finished in 1987. From 1998 on the study is reopened in a modest way. I will also give actual information about the progress of the actual studies and observations. I'm inviting you to give your contributions to and comments on this study and to the theoretical discussion about population dynamics. Because the Gyrinus marinus is very suitable for studies on most important kinds of subjects in population dynamics it was possible that this studie could be done by nearly just one person, and with minimal costs. Nevertheless most of the important population dynamic subjects are considered in this study. I hope that this site will be a good starting point for further discussions on population dynamics. © Robbert van der Eijk | ||
