The genus navicula sensu stricto in the upper lerma basin, MÉxico. I
In order to characterize and analyze the distribution of species of the genus Navicula sensu stricto in the Lerma River and its tributaries, biannual samplings (wet and dry seasons) for the period 2003 to 2005 were made at eleven locations in the Upper Lerma basin, central-western Mexico. Twenty-one...
