Planktonic chlorophyceans of a Brazilian subtropical river: taxonomy and ecological aspects

Abstract

Abstract Given the extreme importance of understanding biodiversity in the contemporary context, this study performed a taxonomic survey of planktonic green algae from a subtropical river in Paraná state, broadening knowledge of the group’s geographic distribution and the environmental conditions related to its occurrence. Monthly samplings of phytoplanktonic material were carried out from February 2015 to January 2016, resulting in the identification of 26 taxa belonging to the classes Chlorophyceae and Trebouxiophyceae, distributed among 16 genera and six taxonomic families. Among the taxa identified, seven are new citations for Paraná.
