Ian W Bishop, Ph.D.
Ian Bishop is a research ecologist at the USGS Southwest Biological Science Center’s Grand Canyon Monitoring and Research Center. His current work is focused on modeling river metabolism and diatom community dynamics in the Glen Canyon tailwater.
Ian’s broader research interests center on diatom ecology and biodiversity, in both freshwater and marine ecosystems. He has expertise in morphological and genomic approaches and applies both to explore how important diatom communities at the base of sensitive and valued food webs respond to rapid environmental change.

Diatoms.org: Supporting taxonomists, connecting communities
Consistent identification of diatoms is a prerequisite for studying their ecology, biogeography, and successful application as environmental indicators. However, taxonomic consistency among observers has been difficult to achieve because taxonomic information is scattered across numerous literature sources, presenting challenges to the diatomist. Firstly, literature is often inaccessible...

Reduction of taxonomic bias in diatom species data
Inconsistency in taxonomic identification and analyst bias impede the effective use of diatom data in regional and national stream and lake surveys. In this study, we evaluated the effect of existing protocols and a revised protocol on the precision of diatom species counts. The revised protocol adjusts four elements of sample preparation, taxon identification and enumeration, and...

Taxonomic harmonization may reveal a stronger association between diatom assemblages and total phosphorus in large datasets
Diatom data have been collected in large-scale biological assessments in the United States, such as the U.S. Environmental Protection Agency’s National Rivers and Streams Assessment (NRSA). However, the effectiveness of diatoms as indicators may suffer if inconsistent taxon identifications across different analysts obscure the relationships between assemblage composition and...

A diatom voucher flora from selected southeast rivers (USA)
This flora is intended to serve as an image voucher for samples analyzed for the U.S. Geological Survey Southeast Stream Quality Assessment (SESQA). The SESQA study included measurement of watershed and water quality parameters to determine the factors that have the greatest potential to alter biotic condition. Algal samples were collected at 108 sites in 2014, from streams representing...
