Information on population characteristics of Paraechinusis is valuable for ensuring long term survival of populations, however, studies are currently lacking. Here we investigate the population dynamics of Ethiopian hedgehogs based on a capture-mark-recapture study in Qatar by fitting Jolly-Seber and Cormack-Jolly-Seber models. Over the 19 months of the study, we estimate a mean population of 60 hedgehogs, giving a density of 7 hedgehogs per km² in our 8.5 km² search area. The monthly abundance of hedgehogs decreased over the study and although survival was constant over the study period, with a mean monthly rate of 75%, there was a decline in the number of new entrants over time. We also studied these parameters over one year, excluding winter, and found that monthly estimates of juvenile and subadult survival decreased over time. We surmise that survival of juveniles may be a factor in the decrease in abundance and there may be implications for the persistence of this population, with anthropogenic influenced resources playing an important role. We caught between 91.3% and 100% of the estimated population at this site, indicating that our capture methodology was efficient. We conclude that the methodology used here is transferrable to other hedgehog species.

卡塔尔人口自由分布的埃塞俄比亚刺猬，Paraechinus aethiopicus的特征和人口统计学。

关于副神经支原体的种群特征的信息对于确保种群的长期生存是有价值的，但是，目前尚缺乏研究。在这里，我们根据卡塔尔的捕获标记捕获研究，通过拟合Jolly-Seber和Cormack-Jolly-Seber模型，调查了埃塞俄比亚刺猬的种群动态。在研究的19个月中，我们估计平均有60只刺猬，在我们8.5 km ^2中的密度为每km ² 7只刺猬搜索区域。在研究中，刺猬的每月丰度下降，尽管在研究期间生存率是恒定的，平均每月率为​​75％，但随着时间的推移，新进入者的数量有所下降。我们还研究了这些参数超过一年的时间（不包括冬季），并发现随着时间的推移，每月的青少年和亚成人生存率估计值下降。我们推测，少年的生存可能是数量减少的一个因素，并且可能对该种群的持久性产生影响，其中人为影响的资源起着重要的作用。我们在该站点捕获了估计人口的91.3％至100％，这表明我们的捕获方法是有效的。我们得出的结论是，这里使用的方法可以转移到其他刺猬物种。
