Microbes, with their vast metabolic capabilities and great adaptability, occupy almost every conceivable ecological niche on Earth – thus, could they survive in the oligotrophic (i.e., nutrient poor) deionized (DI) water that we use for experiments? Observations...

Bacteria surface charge derives its meaning from the cell’s environment; thus, there is no specific surface charge. Determining the surface charge of bacteria in its native environment requires measuring the proxy variable, zeta potential, using cells obtained...

Studies documenting Human-Induced Rapid Evolutionary Change (HIREC) routinely compare contemporary allele or morph frequency distributions with historical baselines. All too often, this involves the re-sampling of a population that was sampled at a single time...

Local (within-sample/alpha) diversity is often implicated as a cause of success or failure of a microbial community. However, the relationships between diversity and emergent properties of a community, such as its stability, productivity, or invasibility, are much...
