Ceratozamia miqueliana is a cycad (Zamiaceae) species endemic to southeastern Mexico. It is currently listed on the International Union for Conservation of Nature (IUCN) Red List as “Critically Endangered” and under Mexican law as “Endangered”. The objective was to complement the evaluation of C. miqueliana based on criterion B of the IUCN, and the method proposed by the Mexican Norm. This information is in turn reinforced with the potential distribution model. We collected data from different herbaria and field visits and obtained the EOO and AOO using GIS and the GeoCat portal, the distribution of the species was modeled using the Maxent program. According to the IUCN guidelines (Geographic distribution, Criterion B) and Mexican law, the species could be considered Endangered and Subject to Special Protection, respectively. The comparison of AOO and EOO obtained by GIS and the GeoCat portal show that both methodologies used coincide in assigning the same categories based on geographic criteria. The integration of the potential distribution helps to identify the environmental factors that influence its habitat, in addition to identifying the ideal sites for its conservation. Is necessary to carry out evaluations of microendemic species such as Ceratozamia miqueliana from different approaches (populations, geographic aspects and habitat evaluation) to obtain more precise results. C. miqueliana must be protected by national and international laws.

评价 Ceratozamia Miqueliana (Zamiaceae) 保护状况的不同标准

Ceratozamia miqueliana 是一种原产于墨西哥东南部的苏铁(Zamiaceae)物种。它目前在国际自然保护联盟 (IUCN) 红色名录中列为“极度濒危”,在墨西哥法律中列为“濒危”。目的是补充基于 IUCN 标准 B 和墨西哥规范提出的方法对 C. miqueliana 的评估。这些信息反过来又通过潜在分布模型得到加强。我们收集了来自不同标本馆和实地考察的数据,并使用 GIS 和 GeoCat 门户获得了 EOO 和 AOO,使用 Maxent 程序对物种的分布进行了建模。根据 IUCN 指南(地理分布,标准 B)和墨西哥法律,该物种可分别被视为濒危物种和受特殊保护。通过 GIS 和 GeoCat 门户获得的 AOO 和 EOO 的比较表明,所使用的两种方法在根据地理标准分配相同类别方面是一致的。潜在分布的整合有助于确定影响其栖息地的环境因素,以及确定其保护的理想地点。有必要从不同的方法(种群、地理方面和栖息地评估)对微型地方性物种(如 Ceratozamia miqueliana)进行评估,以获得更精确的结果。C. miqueliana 必须受到国家和国际法律的保护。潜在分布的整合有助于确定影响其栖息地的环境因素,以及确定其保护的理想地点。有必要从不同的方法(种群、地理方面和栖息地评估)对微型地方性物种(如 Ceratozamia miqueliana)进行评估,以获得更精确的结果。C. miqueliana 必须受到国家和国际法律的保护。潜在分布的整合有助于确定影响其栖息地的环境因素,以及确定其保护的理想地点。有必要从不同的方法(种群、地理方面和栖息地评估)对微型地方性物种(如 Ceratozamia miqueliana)进行评估,以获得更精确的结果。C. miqueliana 必须受到国家和国际法律的保护。
