使用种群生存力分析研究了狂犬病疫苗接种前后红狐狐种群的增长情况。我使用主要基于狩猎袋和道路的已发表研究中的年龄分布和生殖参数构建了生命表来评估死亡率。杀死。基于这些死亡率估计和繁殖估计的模型显示，在狂犬病疫苗接种后，狐狸种群的增长率立即暂时增加。狂犬病根除后不到十年，增长率再次下降。与这些模型一样，袋子统计数据和繁殖巢穴绘图也证实，种群数量可能在 20 世纪 90 年代末稳定在较高水平。对于德国东部貉 Nyctereutes procyonoides 种群，该模型显示出与狂犬病疫苗接种后不久的狐狸种群类似的高增长率。讨论了取决于参数确定性的模型估计的有效性。
Red Fox Vulpes vulpes population growth before and after rabies vaccination was investigated using population viability analysis. I constructed life tables to assess mortality rates using age distribution and reproductive parameters from published studies mainly based on hunting bags and road. kills. Models based on these mortality estimates together with estimates of reproduction revealed temporarily increasing growth rates in fox populations immediately after rabies vaccination. Less than ten years after rabies eradication growth rates had decreased again. Like these models bag statistics and mapping of breeding dens also confirm that populations probably stabilized at a higher level in the end of the 1990s. For the eastern German Raccoon dog Nyctereutes procyonoides populations the model shows high growth rates like in a fox population shortly after rabies vaccination. The validity of model estimates depending on the certainty of parameters is discussed.
