Dynamics of omnivorous crayfish in freshwater ecosystems
In this thesis I examine the dynamics of crayfish in streams and lakes. I have studied the influence of abiotic and biotic factors on abundance, growth, trophic position, niche breadth, and recruitment of crayfish, by conducting field studies, an outdoor channel experiment and timeseries analysis. Overall, the results show that abundance of crayfish is mostly affected by the abundance of predatory
