Before revision:  The increase of the absolute density of nests observed in that area over the monitored period of time leads to an increase of repulsion among neighbouring nests. Central to our approach is the use of well-established ideas from universal spatial structures, which suggest to employ a family of interpolating distributions with only one free parameter that parametrises the repulsionand that correlates well with the concepts from population ecology.
After revision:  The increase of the absolute density of nests observed in that area over the monitored period of time , thereby proving an unexpected yet simple model for density-dependent spacing of predator territories. A similar effect is obtained for next-to-nearest neighbours, albeit with weaker repulsion, indicating a short-range interaction. Our results show that random matrix theory might be useful in the context of population ecology.
