inversely density-dependent natal dispersal in brown bears ursus arctos. | there is considerable controversy in the literature about the presence of density dependence in dispersal. in this study, we exploit a data series from a long-term study (>18 years) on radio-marked brown bears (ursus arctos l.) in two study areas in scandinavia to investigate how individual-based densities influence the probability of natal dispersal and natal dispersal distances. cumulatively, 32% and 46% of the females and 81% and 92% of the males dispersed before reaching 5 years of age in th ... | 2006 | 16489458 |
predicting the potential demographic impact of predators on their prey: a comparative analysis of two carnivore-ungulate systems in scandinavia. | 1. understanding the role of predation in shaping the dynamics of animal communities is a fundamental issue in ecological research. nevertheless, the complex nature of predator-prey interactions often prevents researchers from modelling them explicitly. 2. by using periodic leslie-usher matrices and a simulation approach together with parameters obtained from long-term field projects, we reconstructed the underlying mechanisms of predator-prey demographic interactions and compared the dynamics o ... | 2011 | 22077484 |
