U.S.-Mexico Cooperative Research: Enumeration of the Flora of the Mixteca Region of Oaxaca and Puebla, Mexico

9416309 Panero 该美洲计划奖将资助密歇根州立大学植物标本馆的 Jose Panero 博士和 Drs. 9416309 Panero 之间的研究合作。墨西哥国立自治大学的 Patricia Davila 和 Jose L. Villasenor 对瓦哈卡州和普埃布拉州的 Mixteca Alta 地区进行了植物学探索，编制了该地区所有维管植物的清单。 该项目是密歇根州立大学植物标本馆和墨西哥国家植物标本馆之间持续合作的一部分，旨在出版瓦哈卡州及邻近地区的植物志。 瓦哈卡地区已分为十个研究区域，一次集中关注一个特定的亚植物群。 目前的研究将作为整个瓦哈卡植物志项目的试点项目。 它将包括植物区系的计数，以及实施数据库系统来生成样本数据库，该数据库将准确描述瓦哈卡州的植物区系多样性和分布。 随着项目的成熟，关系数据库系统的其他几个组件也将被开发。 作为为瓦哈卡州准备地图集项目的一部分，此时还将检查该地区主要植被组合的组成和分布。 墨西哥南部的瓦哈卡州拥有该国最丰富的植物群。 尽管物种多样性高且特有程度高，但该州的植物区系从未被系统地清查过，也从未收集过该州所有地区的植物区系。 充分记录和描述该植物区系对于了解北美植物区系主要部分的演化非常重要。 由于该地区承受着越来越大的人类压力，因此有必要在本土植物群进一步消失之前记录其植物群组成。因此，该项目最初的收集工作将旨在在植物群最受灭绝威胁的地区收集尽可能多的标本。 ***

9416309 Panero This Americas Program award will fund a research collaboration between Dr. Jose Panero, Michigan State University Herbarium and Drs. Patricia Davila and Jose L. Villasenor, Universidad Nacional Autonoma de Mexico, for a botanical exploration of the Mixteca Alta region of Oaxaca and Puebla, leading to an inventory of all vascular plants of the region. This project is part of an ongoing collaboration between the Michigan State University Herbarium and the National Herbarium of Mexico to publish the Flora of Oaxaca and adjacent regions. The Oaxaca area has been divided into ten study regions to concentrate attention on one particular sub-flora at a time. The present research will serve as a pilot project for the entire Flora of Oaxaca project. It will include enumeration of the flora, and implementation of a database system to generate a specimen database that will produce an accurate account of the floristic diversity and distribution in the State of Oaxaca. As the project matures, several other components of the relational database system will be developed. The composition and distribution of the major vegetation assemblages in the region will also be examined at this time as part of a project to prepare a chorological atlas for the state of Oaxaca. The southern Mexican state of Oaxaca harbors the richest flora in that country. In spite of the high species diversity and high level of endemism, the flora of the state has never been systematically inventoried, nor all of its areas collected. Adequately documenting and describing this flora is important in understanding the evolution of a major portion of North America flora. Because the area is under increasing human pressure, there is a need to document its floristic composition before further disappearance of the native flora. Therefore, the initial collecting efforts of this project will be directed at gathering as many specimens as possible in an area where the flo ra is most threatened by extinction. ***
