Human activities are causing a global proliferation of cyanobacterial harmful algal blooms (CHABs), yet we have limited understanding how these events affect freshwater bacterial communities. Using weekly data from western Lake Erie in 2014, investigated the community varied over space and time, whether bloom affected non-cyanobacterial (nc-bacterial) diversity composition. Cyanobacterial composition fluctuated dynamically during bloom, but was dominated by Microcystis Synechococcus OTUs....
The bacterial phylum Verrucomicrobia was formally described two decades ago and originally believed to be a minor member of many ecosystems; however, it is now recognized as ubiquitous abundant in both soil aquatic systems. Nevertheless, knowledge the drivers its relative abundance within-phylum habitat preferences remains sparse, especially lake Here, we documented distribution 12 inland lakes Southeastern Michigan, Laurentian Great Lake (Lake Michigan), freshwater estuary, which span...
Hydrogen peroxide (H2O2) has been suggested to influence cyanobacterial community structure and toxicity. However, no study investigated H2O2 concentrations in freshwaters relative blooms when sources sinks of may be highly variable. For example, photochemical production from chromophoric dissolved organic matter (CDOM) vary over the course bloom with changing CDOM UV light water column, while microbial change biomass composition. To assess relationships between harmful algal dominated by...
Oligotyping is a computational method used to increase the resolution of marker gene microbiome studies. Although oligotyping can distinguish highly similar sequence variants, resulting units are not necessarily phylogenetically and ecologically informative due limitations selected gene. In this perspective, we examine how data interpreted in recent literature, illustrate some method's constraints with case study harmful bloom-forming cyanobacterium Microcystis. We identified three...
Abstract The relationship between animals and their gut flora is simultaneously one of the most common complex symbioses on Earth. Despite its ubiquity, our understanding this invisible but often critical still in infancy. We employed adult Neotropical butterflies as a study system to ask three questions: First, how does microbial community composition vary across host individuals, species dietary guilds? Second, do microbiota compare food communities? Finally, are functionally adapted...
Blooms of the potentially toxic cyanobacterium Microcystis are increasing worldwide. In Laurentian Great Lakes they pose major socioeconomic, ecological, and human health threats, particularly in western Lake Erie. However, interpretation "omics" data is constrained by highly variable genome small number reference sequences from strains isolated Lakes. To address this, we sequenced two isolates Erie (Microcystis aeruginosa LE3 M. wesenbergii LE013-01) one upstream St. Clair (M. cf LSC13-02),...
In the oligotrophic oceans, key autotrophs depend on "helper" bacteria to reduce oxidative stress from hydrogen peroxide (H2O2) in extracellular environment. H2O2 is also a ubiquitous stressor freshwaters, but effects of and their interactions with are less well understood freshwaters. Naturally occurring freshwater systems proposed impact proportion microcystin-producing (toxic) non-microcystin-producing (nontoxic) Microcystis blooms, which influences toxin concentrations human health...
Relative abundance profiles of bacterial populations measured by sequencing DNA or RNA marker genes can widely differ. These differences, made apparent when calculating ribosomal RNA:DNA ratios, have been interpreted as variable activities populations. However, inconsistent correlations between ratios and metabolic activity growth rates led to a more conservative interpretation this metric the cellular protein synthesis potential (PSP). Little is known, particularly in freshwater systems,...

Abstract Often coauthored by university‐ and school‐based educators, preservice teachers, youths, this department column considers how literacies are best developed through context‐crossing partnerships among university, school, community constituents.
The mathematician Paul Halmos once wrote that although mathematics consists of many things—such as theorems, axioms, and definitions—the heart problems (1980). Indeed, in classrooms around the world, teachers students dedicate a substantial portion their time to presenting solving problems. These often require application previously presented procedures enable readily identify method needed solve them.

Mechanical computing has seen resurgent interest recently owing to the potential embed sensing and computation into new classes of programmable metamaterials. To realize this, however, one must push signals from part a device another, do so in way that can be reset robustly. We investigate propagation bistable mechanical cascade uphill energy. By identifying penetration length for perturbations, we show propagate finite distances map out parameters this occur. Experiments on soft elastomers...
