Daphnia populations often show rapid microevolutionary adaptation to environmental changes. Here, we investigated the possibility that microevolution of Daphnia populations could be driven by natural sestonic Protease Inhibition (PI). We hypothesized that PI changes seasonally, which might lead to concomitant changes in tolerance to PI in a co-occurring(More)
Determining genetic variation at the DNA level within and between natural populations is important for understanding the role of natural selection on phenotypic traits, but many techniques of screening for genetic variation are either cost intensive, not sensitive enough or too labour- and time-consuming. Here, we demonstrate high-resolution melting(More)
It is known that cyanobacteria negatively affect herbivores due to their production of toxins such as protease inhibitors. In the present study we investigated potential interspecific differences between two major herbivores, Daphnia magna and Daphnia pulex, in terms of their tolerance to cyanobacteria with protease inhibitors. Seven clones each of D. magna(More)
Protease inhibitors of primary producers are a major food quality constraint for herbivores. In nutrient-rich freshwater ecosystems, the interaction between primary producers and herbivores is mainly represented by Daphnia and cyanobacteria. Protease inhibitors have been found in many cyanobacterial blooms. These inhibitors have been shown (both in vitro(More)
Traffic systems of major cities have reached a high level of sophistication, yet, we think their heterogeneity difficult. Ever-new mobility concepts occur, such as car or ride sharing. It is our opinion that a holistic consideration of all available concepts may provide significant benefits. In this paper we present such consideration in the form of an open(More)
Computer systems are becoming more and more ubiquitous. Many of to-day's application areas do not fit for monolithic approaches, but for distributed intelligent systems. The multi-agent paradigm is an appropriate and therefore popular approach for building these systems. To interpret messages and provided services the agents need a common ontology.(More)
