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

9416309帕内罗这个美洲项目奖将资助密歇根州立大学植物标本馆的何塞·帕内罗博士与墨西哥国立自治大学的帕特里夏·戴维拉博士和何塞·L·维拉塞诺博士之间的研究合作，对瓦哈卡和普埃布拉的Mixteca Alta地区进行植物学探索，从而对该地区的所有维管植物进行清查。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正在进行的合作的一部分，目的是出版瓦哈卡州和邻近地区的植物群。瓦哈卡地区已被划分为十个研究区域，以便每次只关注一个特定的亚植物区系。本研究将作为整个瓦哈卡植物区系项目的试点项目。它将包括植物区系的列举，以及建立一个数据库系统，以生成一个标本数据库，准确说明瓦哈卡州的植物区系多样性和分布。随着项目的成熟，还将开发关系数据库系统的其他几个组成部分。作为编制瓦哈卡州脉络地图集项目的一部分，目前还将审查该区域主要植被群落的组成和分布。墨西哥南部的瓦哈卡州拥有该国最丰富的植物。尽管有很高的物种多样性和高度的地方性，但该州的植物区系从未被系统地清点过，也没有收集过它的所有区域。充分记录和描述这一植物区系对于理解北美植物区系的主要部分的演化是重要的。由于该地区承受着越来越大的人类压力，在当地植物进一步消失之前，有必要记录其植物区系组成。因此，该项目的初步收集工作将致力于在生物灭绝威胁最大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. ***
