U.S.-Argentina Cooperative Science Program: Biodiversity and Ecology of Chrysophyta in the Parana River Region (Argentina)

9301833西弗美国-阿根廷合作科学奖将支持康涅狄格学院的彼得·西弗和阿根廷布宜诺斯艾利斯大学的玛丽亚·维格纳的合作。该项目旨在研究巴拉那河水系中藻类植物金藻的生物多样性和生态需求。金藻，特别是有鳞片的物种，是水生生物最重要的指示生物之一。它们在亚热带水域的生物多样性知之甚少。该项目是一项大规模研究的初始阶段，将描述河流三角洲地区物种的组成和沿环境梯度的分布。植物区系将与其他亚热带、热带、温带和北极地区进行比较，以了解该藻类群的空间分布。不为科学所知的生物将被识别和描述。美国和阿根廷双方都将受益于开发一个数据库，用于古水文学推断工作，旨在了解人类干扰对水生资源的影响。***

9301833 Siver This U.S.-Argentina Cooperative Science award will support the collaboration of Peter Siver of Connecticut College and Maria Vigna of the University of Buenos Aires, Argentina. The project aims to examine the biodiversity and ecological requirements of the algal flora Chrysophyta in the Parana River system. The Chrysophyta, especially the scale-bearing species, represent one of the most important bioindicator groups of aquatic organisms. Their biodiversity in subtropical waters is poorly understood. This project, an initial phase of a large-scale study, will describe the composition and distribution of species along environmental gradients for the river's deltaic region. The flora will be compared to other subtropical, tropical, temperate, and arctic regions in order to understand the spatial distribution of this algal group. Organisms not known to science will be identified and described. Both the U.S. and the Argentine sides will benefit from development of a database for use in paleolimnological inference work aimed at understanding the effects of human disturbances on aquatic resources. ***
