This project investigates the biodiversity of Mexico, the country with the greatest number of amphibians and reptiles in the world. A collaboration is proposed between the University of Texas at Arlington and the Universidad Nacional Autonoma de Mexico. Participants will conduct a comprehensive survey of the amphibians, reptiles, and the parasite fauna associated with these classes. The investigators will focus their efforts on northern Mexico from the Transverse Volcanic Cordillera to the US border. Mexico is of particular biogeographical interest because it includes the transition zone between the two great faunal regions of the Western Hemisphere, the Neartic and Neotropical. It is estimated that more than 200 species of amphibians and reptiles unknown to science remain to be discovered in Mexico, and the parasites in general are extremely poorly known. The urgency for this project is more acute than for other tropical countries, for several reasons. First, human population density in Mexico has now reached the point where the last vestiges of forests are disappearing in many areas, and these forests are recognized for their extremely high biodiversity and levels of endemism. Second, the diversity of amphibians and reptiles in Mexico is higher than any other country in the world, regardless of size or location. Finally, dramatic population declines have been identified in both amphibians and reptiles; some species have already been lost and others will follow soon. The materials collected (specimens, tissue samples, digital images, recordings) during this survey will be valuable aids to persons working in many diverse disciplines of research, including systematics, ecology, and conservation.

该项目调查墨西哥的生物多样性，该国是世界上两栖动物和爬行动物数量最多的国家。德克萨斯大学阿灵顿分校和墨西哥国立自治大学拟开展合作。 参与者将对两栖动物、爬行动物以及与这些类别相关的寄生虫动物群进行全面调查。 调查人员将重点关注墨西哥北部从横向火山山脉到美国边境的地区。 墨西哥具有特殊的生物地理意义，因为它包括西半球近地和新热带两大动物区之间的过渡带。 据估计，墨西哥仍有超过 200 种科学未知的两栖动物和爬行动物有待发现，而一般来说，人们对寄生虫知之甚少。 由于多种原因，该项目的紧迫性比其他热带国家更为紧迫。 首先，墨西哥的人口密度现已达到许多地区最后的森林正在消失的程度，而这些森林因其极高的生物多样性和特有程度而受到认可。 其次，墨西哥两栖动物和爬行动物的多样性高于世界上任何其他国家，无论大小或位置如何。 最后，两栖动物和爬行动物的数量急剧下降。有些物种已经消失，其他物种很快就会消失。本次调查期间收集的材料（标本、组织样本、数字图像、录音）将为从事许多不同学科研究（包括系统学、生态学和保护学）的人们提供宝贵的帮助。
