Iberian lynx distribution is currently restricted to the south of the Iberian Peninsula. Nevertheless, there is evidence of the presence of several small groups in the peninsular centre that have been forgotten by management and conservation actions. In this research, we gathered evidences of Iberian lynx presence along 21 transects located in the southwest of the Madrid province. In these transects lynx DNA was identified in 47 scats, which scientifically proves the presence of the species in that location. Using these locations (presence-only data) we built a maximum entropy model (MaxEnt) to estimate the suitability of the study area for the species. Our results show the existence of an almost continuous area that is approximately 744 km2 that is suitable for the Iberian lynx. Seventy-eight percent of this area is within the Natura 2000 network and, therefore, it falls under regulations to preserve and restore habitat types, flora and fauna. This study shows the suitability of this territory has for the Iberian lynx.

使用MaxEnt算法评估伊比利亚中部半岛潜在伊比利亚天猫座种群的栖息地适宜性

目前,伊比利亚的分布仅限于伊比利亚半岛的南部。但是,有证据表明,半岛中心地区存在着一些被管理和保护行动遗忘的小团体。在这项研究中,我们收集了位于马德里省西南部21个样带的伊比利亚山猫的证据。在这些样带中,发现了47只粪便中的lynx DNA,科学证明了该位置存在该物种。使用这些位置(仅存在数据),我们建立了最大熵模型(MaxEnt)来估计研究区域对物种的适合性。我们的结果表明存在大约744 km 2的几乎连续的区域适用于伊比利亚。该地区的百分之七十八在Natura 2000网络中,因此,它属于保护和恢复栖息地类型,动植物的法规。这项研究表明,该地区对伊比利亚山猫的适宜性。
