A web-based tool for assessing the condition of benthic diatom assemblages in streams and rivers of the conterminous United States Open
Benthic diatom assemblages are known to be indicative of water quality but have yet to be widely adopted in biological assessments in the United States due to several limitations. Our goal was to address some of these limitations by develo…

<i>Diatoms.org</i>: supporting taxonomists, connecting communities Open
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 …

Taxonomy and nomenclature of some members within the Obtusae section of Nitzschia Hassall (Bacillariophyceae) including descriptions of two new species Open
Light and scanning electron microscope observations are made on some members of the section Obtusae in the genus Nitzschia (Bacillariales, Bacillariophyceae).We use type and other material derived from both the National Water Quality Asses…

Studies on type material from Kützing’s diatom collection IV: The basionym, author and type of Tetracyclus rupestre Open
While describing the species Tetracyclus hinziae I. Bishop & Spaulding (2015, p. 200), it was noticed that the basionym and type specimens of the similar species Tetracyclus rupestre was unclear. This short note addresses those concerns.

Resources and Practices to Improve Diatom Data Quality Open
Environmental programs in the United States face technical challenges that inhibit the ability to use diatoms in water quality monitoring and assessment projects. Specifically, inconsistent taxonomy can obscure diatom responses to environm…

The peacock in the room: confronting the hidden curriculum of androcentrism and gender bias in undergraduate biology education. Open
This dissertation exposes one manifestation of the hidden curriculum of gender bias in the biological academe and explores the impacts of implicit essentialist perspectives on biology curricula and student understanding of an important evo…

Nutrients and warming interact to force mountain lakes into unprecedented ecological states Open
While deposition of reactive nitrogen (N) in the twentieth century has been strongly linked to changes in diatom assemblages in high-elevation lakes, pronounced and contemporaneous changes in other algal groups suggest additional drivers. …

Reduction of taxonomic bias in diatom species data Open
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…

Diatom enumeration method influences biological assessments of southeastern USA streams Open
Current fixed-count enumeration methods for benthic diatoms are likely inadequate for most research and monitoring objectives. These methods underestimate taxa richness and may fail to detect losses of species caused by human impacts. Cons…

Enhancing Percolation in Phosphatic Clay Using Diatoms under Laboratory Conditions Open
Clay settling areas are large impoundments brought about by phosphate mining with water-holding capacity that renders it very poor for agriculture and crop production. This study aims to enhance water percolation in phosphatic clay using p…

Environmental DNA reveals the structure of phytoplankton assemblages along a 2900-km transect in the Mississippi River Open
The environmental health of aquatic ecosystems is critical to society, yet traditional assessments of water quality have limited utility for some bodies of water such as large rivers. Sequencing of environmental DNA (eDNA) has the potentia…

Proteogenomic analyses indicate bacterial methylotrophy and archaeal heterotrophy are prevalent below the grass root zone Open
Annually, half of all plant-derived carbon is added to soil where it is microbially respired to CO 2 . However, understanding of the microbiology of this process is limited because most culture-independent methods cannot link metabolic pro…
