The high loss rate of forest ecosystem by deforestation in the Trans-Mexican Volcanic Belt is one of the principal ecological problems of central Mexico, even in natural protected areas. We compiled a checklist and determined β-diversity indexes of amphibians and reptiles of the highly disturbed protected area, La Malinche National Park (LMNP) in Mexico, to determine the principal habitats for herpetofaunal conservation. After our extensive eight-year field sampling, we documented 28 species (nine amphibians and 19 reptiles), representing 11 families and 18 genera; four of these species are new records for LMNP. Of the species, 89% are endemic to Mexico. The IUCN Red List considers 22 species as Least Concern, one as Near Threatened, and four as Vulnerable. Meanwhile, the Environmental Viability Scores categorize three species as low vulnerability, 15 as medium, and 10 as high. According to the Mexican list of protected species, eight species are under Special Protection and nine are considered Vulnerable. The dissimilarity index between habitat types (βsør) in both groups is high, principally due to the environmental gradient generated by the altitudinal range. and Pine forest are high diversity areas for amphibians and reptiles, respectively, and must be considered for special protection. LMNP hosts more than 60% of the herpetofauna of Tlaxcala and is the principal "conservation island" for this state. Therefore, based on the percentage of state species represented, endemism and the current social and ecological problems, additional efforts that involve the local communities to protect the biodiversity of this National Park are necessary.
跨墨西哥火山带森林砍伐导致的森林生态系统高损失率是墨西哥中部的主要生态问题之一，即使在自然保护区也是如此。我们编制了一份清单，并确定了墨西哥受高度干扰的保护区马林切国家公园（LMNP）两栖动物和爬行动物的β多样性指数，以确定保护两栖爬行动物的主要栖息地。经过为期八年的广泛实地采样，我们记录了28个物种（9种两栖动物和19种爬行动物），代表11个科和18个属；其中4个物种是LMNP的新记录。这些物种中，89%是墨西哥特有的。世界自然保护联盟红色名录将22个物种列为无危，1个列为近危，4个列为易危。同时，环境生存能力得分将3个物种归类为低脆弱性，15个为中等，10个为高。根据墨西哥受保护物种清单，8个物种受到特别保护，9个被视为易危。两组栖息地类型之间的相异指数（βsør）很高，主要是由于海拔范围产生的环境梯度。阔叶林和松林分别是两栖动物和爬行动物的高多样性区域，必须予以特别保护。LMNP拥有特拉斯卡拉州60%以上的两栖爬行动物，是该州主要的“保护岛”。因此，基于该州物种所占比例、特有性以及当前的社会和生态问题，有必要做出更多努力，让当地社区参与保护这个国家公园的生物多样性。
