US-Austria Cooperative Research: Leafy Spurges (Euphorbia) of Austria

印第安纳大学布鲁明顿分校的Paul G.Mahlberg博士和奥地利维也纳大学植物园的F.Ehrendorfer博士提出的关于“奥地利的树叶植物”的建议，是由美国国家科学基金会和奥地利FWF根据美国-奥地利合作科学计划共同批准的。调查人员将对奥地利本土的斯普兰进行形态、化学和细胞学特征的分析。马哈伯格博士将获得有关奥地利各地的豆科植物分类群的大量数据，而埃伦多费尔博士将能够将这些关于乳管组成的数据整合到他对豆科植物的细胞分类学研究中。马哈伯格博士希望确定奥地利野牛与美国野牛的分类亲缘关系，作为有效拟议的生物防治计划的先决条件，以控制这种杂草，目前这种杂草正在给养牛业造成重大经济损失，这样就可以针对已知的宿主类群引入特定的捕食者。

This proposal on "Leafy Spurges (Euphorbia) of Austria" between Dr. Paul G. Mahlberg of Indiana University Bloomington and Dr. F. Ehrendorfer of the Botanical Garden, University of Austria, Vienna, is jointly approved by NSF and the FWF of Austria under the US- Austria Cooperative Science Program. The investigators will analyze the native spurges of Austria for morphological, chemical, and cytological characters. Dr. Mahlberg will derive extensive data on the taxa of the spurges throughout Austria, while Dr. Ehrendorfer will be able to integrate these data on laticifer composition into his cytotaxonomic studies of the spurges. Dr. Mahlberg hopes to determine the taxonomic affinities of Austrian spurges with those in the US as a prerequisite for an effective proposed biocontrol program to control this weed, now causing significant economic losses in the cattle industry, so that specific predators can be introduced for known populations of host taxa.
