Oral or poster: Poster

A 2-dimensional predator-prey model with five parameters is
investigated, adapted from the Volterra-Lotka system by a
non-monotonic response function. A description of the various
domains of structural stability and their bifurcations is given. The
bifurcation structure is reduced to four organising centres of
codimension 3. Research is initiated on time-periodic perturbations
by several examples of strange attractors.
