Breeding biology, mating system and population dynamics of the Lesser Spotted Woodepcker (Picoides minor) : combining empirical and model investigations
… dynamics. In the field studies I collected basic demographic data of reproductive success and mortality. Moreover, breeding biology and behaviour were investigated in detail. My results showed a significant decrease of the reproductive success with later timing of breeding, caused by deterioration …

Stochastic dynamics in spatially extended physical and biological systems
… nature in spatially extended systems: (1) a noise induced mechanism for the emergence of biological homochirality in early life self-replicators, (2) the amplification effect of nonnormality on stochastic Turing patterns in reaction diffusion systems, and (3) the velocity statistics of edge …

Spatial-temporal patterns in evolutionary ecology and fluid turbulence
… behavior of the stochastic dynamics from demographic noise without any additional and more biologically detailed assumptions. (2) Second, we address the question of the role of selection in evolution and its relationship with phenotypic fluctuations. Phenotypic fluctuations have been …

Diversity and evolution of ecosystems: From genomes to the biosphere
… thus acts as a parasite. We have found that the demographic noise due to the discreteness of element copy numbers leads to noisy oscillations on the evolutionary time scale, in a similar way to that resulting in the predator-prey quasi-cycles in ecology. By viewing these DNA elements as predators …
