POPULATION DYNAMICS OF THE LYNX (LYNX LYNX) IN THE BIALOWIEZA PRIMEVAL FOREST REVISITED:A STATISTICAL ANALYSIS OF DENSITY-DEPENDENT MIGRATION
Journal Title: ELECTRONIC JOURNAL OF POLISH AGRICULTURAL UNIVERSITIES - Year 2008, Vol 11, Issue 4
Abstract
This paper applies a two-patch model to the population dynamics of the lynx which lives in the Bialowieza Primeval Forest (BPF) that extends along the Poland–Belarus border, and discusses the implications of the results obtained. In the estimation process, we performed a unit root test to avoid spurious correlation, and subsequently, we estimated the parameter values for the model. We obtained a relatively high instantaneous growth rate. The ecological parameter values in Poland were higher than those in Belarus, suggesting that the policy applied in Poland is more conservative than the one applied in Belarus. Finally, we conclude the paper by suggesting that the conservation of the BPF and the extension of the reserve area are crucial for the wildlife in the region.
