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

9416309 帕内罗 这个美洲计划奖将资助密歇根州立大学植物标本室的何塞·帕内罗博士和帕特里夏·达维拉博士和何塞·L·帕内罗博士之间的研究合作。 Villasenor，墨西哥国立自治大学，对瓦哈卡和普埃布拉的Mixteca阿尔塔地区进行植物学探索，并对该地区的所有维管植物进行了编目。 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，以出版瓦哈卡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，集中注意力在一个特定的亚植物群的时间。 本研究将作为整个瓦哈卡植物群项目的试点项目。 它将包括植物群的统计，以及建立一个数据库系统，以建立一个标本数据库，准确地说明瓦哈卡州的植物多样性和分布情况。 随着项目的成熟，将开发关系数据库系统的其他几个组成部分。 作为编制瓦哈卡州地理分布图项目的一部分，目前还将对该区域主要植被组合的组成和分布进行审查。 墨西哥南部的瓦哈卡州拥有该国最丰富的植物群。 尽管物种多样性和特有性很高，但该州的植物群从未被系统地编目，也没有收集所有地区。 准确地记录和描述这一植物群对于理解北美植物群的主要部分的进化是重要的。 由于该地区受到越来越大的人类压力，有必要在本地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致力于在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. ***
