Diatom Flora of the New Jersey Coastal Wetlands
(Trenton, N.J. : Department of Environmental Protection, 2019-08-21) Desianti, Nina; Potapova, Marina
In 2012-2017 the New Jersey Department of Environmental Protection sponsored several research projects aimed at evaluating the potential use of diatoms for monitoring present and inferring past environmental conditions in New Jersey coastal wetlands. The goal of this report is to document the most common diatom taxa from studied wetlands, with high-resolution light and electron microscopy images. The images of 499 taxa found in the sub-, inter- and supratidal habitats and in sediment core samples are presented. Genera with the most species are Navicula (148), Fallacia (34), Nitzschia (21), and Parlibellus (16). Some taxa could not be identified to species level and are listed under provisional names. Voucher slides are deposited in the Diatom Herbarium of the Academy of Natural Sciences of Drexel University.

Pilot project: Evaluation of DNA-based metabarcoding of microeukaryotic assemblages for water-quality monitoring in New Jersey rivers and streams: Final Report
(Trenton, N.J. : Department of Environmental Protection, Division of Science and Research, 2019-01-23) Potapova, Marina; Minerovic, Alison
The goal of this pilot project was to explore the DNA metabarcoding approach to biological assessment of New Jersey wadeable streams. We used methodology previously recommended to characterize the whole eukaryotic community by Illumina Mi-Seq sequencing of the V9 fragment of 18S rDNA gene following the Earth Microbiome Project protocol. In order to compare the outcome of molecular characterization of stream biofilms community with traditional microscopy-based assessment, we also enumerated diatoms in the same samples. To evaluate the response of biofilm communities to impairment we sampled 14 sites along a disturbance gradient. To estimate variability of the results obtained by both methods, we analyzed three field replicate samples per sampling site and two lab replicates per sample, which were two separate DNA extractions.
