This U.S.-Slovak Research on SCENEDESMUS Systematics is between Dr. Francis R. Trainor of the University of Connecticut and Dr. Frantisek Hindak of the Institute of Botany, Bratislava. The reseachers' work will focus on the phenotypic variability and plasticity of this well-known group of freshwater planktonic algae. Numerous recent laboratory studies of several species of SCENEDESMUS confirm that phenotypic plasticity is common within the genus; some species are far more plastic than others. In their efforts Drs. Trainor and Hindak will work with both light microscope (LM) and ultrastructural features (EM). First, they will complete analysis of the full range of plasticity in S. ARMATUS. They then intend to propose an amended species description with which one could identify the species in the field relying on an ecomorph or two. Studies with additional species (e.g., S. COMMUNIS, S. MAXIMUS. S. ABUNDANS, and S. OBLIQUUS) would follow. Simultaneously, they hope to confirm plasticity in EM features and hypothesize that they can place the individual wall ultrastructural features in an ordered sequence of development. Results will contribute to our knowledge of fundamental aspects of morphological plasticity in phytoplankton and are expected to advance the fields of algal systematics and freshwater ecology. This project in botany fulfills the program objectives of advancing science by enabling leading experts in the U.S. and Slovakia to combine complementary talents and pool research resources in areas of strong mutual interest and competence.

这个美国-斯洛伐克对SCENEDESMUS的研究 系统学是博士之间的弗朗西斯R。培训师 康涅狄格大学和Frantisek博士 布拉迪斯拉发植物研究所的Hindak说。 研究人员的工作将集中在表型 这种众所周知的 淡水浮游藻类的一个类群。 许多 最近的实验室研究的几种 SCENEDESMUS证实，表型可塑性是 在属内常见;有些种类远 塑料比其他的多。 在他们的努力博士。 Trainor和Hindak将使用两种光 光镜和超微结构特征 （EM）中指定的值。 首先，他们将完成对 S.阿玛塔斯。 他们 然后打算提出一个修正的物种 可以用来识别 依赖于生态形态或 两个. 其他物种的研究（例如，S. 科穆尼斯麦克斯。S. ABUNDANS和S. ObjectiveUS）将继续。 他们同时 希望确认电磁特征可塑性， 假设他们可以将个体 细胞壁超微结构特征 发展的顺序。 结果将有助于 我们对人类的基本知识 浮游植物的形态可塑性， 预计将推动藻类领域 系统学和淡水生态学。 这个植物学项目实现了 促进科学发展的目标 美国和斯洛伐克的顶尖专家 联合收割机互补人才，集中研究 共同感兴趣的领域的资源， 能力。
