Aquatic invasive species (AIS) are of concern in North America due to their devastating impacts on ecosystems and economies. The Great Lakes region is particularly vulnerable AIS introduction establishment with at least 184 nonindigenous reported this from a large number taxa including viruses, bacteria, diatoms, protozoa, arthropods, mollusks, fish, plants. Representative these groups were explored, describing the features natural history current efforts prevention control. Specifically,...
Community-based microbial source tracking (MST) utilizes high-throughput DNA sequencing to profile and compare the communities in different fecal sources environmental samples. SourceTracker, a program that compares library of OTUs from (i.e., sources) those samples sinks) order determine contamination, is an emerging tool for community-based MST studies. In this study, we investigated ability SourceTracker known contamination spiked, situ mesocosms containing contributors. We also evaluated...
In methanogenic habitats, volatile fatty acids (VFA), such as propionate and butyrate, are major intermediates in organic matter degradation. VFA further metabolized to H(2), acetate CO(2) by syntrophic acid-degrading bacteria (SFAB) association with archaea. Despite their indispensable role degradation, little is known about SFAB abundance environmental distribution. To facilitate ecological studies, we developed four novel genus-specific quantitative PCR (qPCR) assays, primer sets...
The trajectories of nanoscale particles through microscale environments record useful information about both the and environments. Optical microscopes provide efficient access to this measurements light in far field from nanoparticles. Such necessarily involve trade-offs tracking capabilities. This article presents a measurement framework, based on theory, that facilitates more systematic understanding such rationally design systems for diverse applications. framework includes degrees...
Anaerobic treatment is a sustainable and economical technology for waste stabilization production of methane as renewable energy. However, the process under-utilized due to operational challenges. Organic overload or toxicants can stress microbial community that performs degradation, resulting in system failure. In addition, not all methanogenic communities are equally capable consistent, maximum biogas production. Opinion varies which parameters should be used monitor fitness digester...
Colibactin is a recently characterized pro-carcinogenic genotoxin produced by
Sea lamprey (SL; Petromyzon marinus), one of the oldest living vertebrates, have a complex metamorphic life cycle. Following hatching, SL transition into microphagous, sediment burrowing larval stage, and after 2-10+ years, larvae undergo dramatic metamorphosis, transforming parasitic juveniles that feed on blood bodily fluids fishes; adult cease feeding, spawn, die. Since gut microbiota are critical for overall health all animals, we examined associated with SLs in each history stage. We...
Methanogens are a diverse group of archaea that play critical role in the global carbon cycle. The lack appropriate molecular tools to simultaneously quantify numerous methanogenic taxa, however, has largely limited our ability study these communities wide variety habitats, such as anaerobic digesters (ADs). In this study, 34 probe-based quantitative PCR (qPCR) assays were designed target all known genera within archaeal phylum Euryarchaeota. These qPCR adapted high-throughput microfluidic...
We introduce an implementation of magnetophoresis to measure the absolute magnetization ferromagnetic nanorods dispersed in fluids, by analyzing velocity single under applied magnetic field gradient. A microfluidic guideway prevents aggregation nanorods, isolates them, and confines their motion for analysis. use a three-dimensional imaging system precisely track nanorod particle-surface proximity. test effect on gradient application, finding that it guides magnetophoresis, but imposes...
Abstract Host-associated microbiota play a critical role in host fitness by providing nutrition, enhancing digestion capabilities, and protection from pathogens. Here, we investigated the effects of two environmental stressors, temperature, salinity, on associated with zebra mussels (ZMs), highly invasive bivalve North America. To examine this detail, lake-collected ZMs were acclimated to laboratory conditions, subjected temperature salinity stress conditions. The impact these stressors...
Bacterial communities that inhabit the surface of aquatic plants are thought to play a critical role in relation host fitness and function. However, little is known about their structure dynamics comparison with those bacterioplankton. In this study, we performed comprehensive spatial temporal characterization epibacterial associated Eurasian watermilfoil (EWM; Myriophyllum spicatum), an invasive macrophyte, which has established itself thousands lakes across North America. EWM samples were...
