Strafbarkeit des Bannbruchs
(2013)
Der vorliegende 3. Band der „Schriften zum deutschen und russischen Strafrecht“ enthält die Vorträge, die an dem „Internationalen rechtsvergleichenden Runden Tisch zu aktuellen Themen des deutschen und russischen Strafrechts“, der am 18. Dezember 2012 an der Juristischen Fakultät der Universität Potsdam stattgefunden hat, gehalten wurden. Die Beiträge der Wissenschaftler und Praktiker aus Russland und Deutschland decken ein breites Spektrum an Themen ab, die in beiden Ländern von Interesse sind. In den Band aufgenommen wurden zudem der Festvortrag von Prof. Dr. Rarog zum Tag der Juristischen Fakultät der Universität Potsdam am 20. Juni 2012, ein Beitrag von Prof. Dr. Matskevich sowie ein weiterer Aufsatz von Prof. Dr. Rarog und Dr. Nagaeva. Die Publikation der Beiträge in deutscher und russischer Sprache ermöglicht den Lesern in beiden Ländern die Lektüre in der jeweiligen Muttersprache.
In the context of ecological risk assessment of chemicals, individual-based population models hold great potential to increase the ecological realism of current regulatory risk assessment procedures. However, developing and parameterizing such models is time-consuming and often ad hoc. Using standardized, tested submodels of individual organisms would make individual-based modelling more efficient and coherent. In this thesis, I explored whether Dynamic Energy Budget (DEB) theory is suitable for being used as a standard submodel in individual-based models, both for ecological risk assessment and theoretical population ecology. First, I developed a generic implementation of DEB theory in an individual-based modeling (IBM) context: DEB-IBM. Using the DEB-IBM framework I tested the ability of the DEB theory to predict population-level dynamics from the properties of individuals. We used Daphnia magna as a model species, where data at the individual level was available to parameterize the model, and population-level predictions were compared against independent data from controlled population experiments. We found that DEB theory successfully predicted population growth rates and peak densities of experimental Daphnia populations in multiple experimental settings, but failed to capture the decline phase, when the available food per Daphnia was low. Further assumptions on food-dependent mortality of juveniles were needed to capture the population dynamics after the initial population peak. The resulting model then predicted, without further calibration, characteristic switches between small- and large-amplitude cycles, which have been observed for Daphnia. We conclude that cross-level tests help detecting gaps in current individual-level theories and ultimately will lead to theory development and the establishment of a generic basis for individual-based models and ecology. In addition to theoretical explorations, we tested the potential of DEB theory combined with IBMs to extrapolate effects of chemical stress from the individual to population level. For this we used information at the individual level on the effect of 3,4-dichloroanailine on Daphnia. The individual data suggested direct effects on reproduction but no significant effects on growth. Assuming such direct effects on reproduction, the model was able to accurately predict the population response to increasing concentrations of 3,4-dichloroaniline. We conclude that DEB theory combined with IBMs holds great potential for standardized ecological risk assessment based on ecological models.
