In the city, rabbits build more densely
European wild rabbits (Oryctolagus cuniculus) not only achieve high population densities in the city, their burrows are also built more densely and on a smaller external scale. That is something researchers in the Goethe University's Task Force on Ecology and Evolution have discovered in their study on wild rabbit populations in and around Frankfurt. As they report in the advance version of the Journal of Zoology, small burrow structures with fewer entrances and exits predominate in Frankfurt's inner city. These structures are inhabited by few animals - often only pairs or single wild rabbits. In contrast to this, the structural systems in the rural environs of Frankfurt are substantially larger and are also inhabited by larger social rabbit groups.
