This review presents the state-of-the-art of benthic soft-bodied algae as biondicators of
stream and river water quality, with emphasis on bioassessments set by the legislation (eg …

Algae have a long history of use in indicating ecological condition of streams and lakes.
Various algae-based indicators have been developed and used in stream and lake water …

Predictive biological indices have transformed the bioassessment landscape by allowing
universal indices to be applicable across diverse environments. The successful …

The diatom genus Planothidium from streams and rivers in California was studied by
applying the most current species designations. Twenty Planothidium taxa were identified in …

A key challenge in managing flow alteration is determining the severity and pattern of
alteration associated with the degradation of biological communities. Understanding these …

The nucleotide sequences (18S and rbc L) of the freshwater diatom strain UTEX FD23 were
revisited and its morphology studied for the first time. This strain is maintained at the UTEX …

Assessments of the ecological health of algal assemblages in streams typically focus on
measures of their local diversity and classify individuals by morphotaxonomy. Such …

Light and scanning electron microscopic observations of three new species of freshwater
gomphonemoid diatoms are presented from mountain streams in California: Gomphonema …

Planothidium sheathii sp. nov., a new species from rivers in California, USA, is described
based on light and scanning electron microscopy. P. sheathii has broadly lanceolate to …

ABSTRACT The Los Angeles region contains a number of heavily altered watersheds,
resulting in the degradation of both water and habitat quality along numerous streams …
