TL;DR: It is shown that 16S rRNA sequences of >99 % identity can represent functionally distinct microorganisms, rendering OTU clustering problematic when the goal is an accurate analysis of organism distribution, and recommended to minimize the number of PCR cycles in DNA library preparation and apply strict postsequencing QC filters to reduce the most prevalent artifacts.

TL;DR: Based upon the microbial community composition and the isotopic signature of methane associated with the Cook Inlet basin site, a simplified reaction network beginning with the breakdown of coal macromolecules, followed by fermentation and methylotrophic and acetoclastic methane production is proposed.

TL;DR: The results imply that phytoplankton provided poor food web support for higher trophic levels, probably contributing to the long-term decline in fish abundance in the brackish to freshwater region of the San Francisco Estuary.

TL;DR: Corteva Agriscience, USA Department of Soil and Crop Sciences, Colorado State University, USA c Department of Agronomy and Horticulture, University of Nebraska and University of Missouri as discussed by the authors.

TL;DR: Analysis of genetic genetic diversity of microbialites living in different types of environments throughout Mexico showed that microbialite communities were very diverse and showed geographic variation in composition, as well as an environmental effect related to pH and conductivity, which together explained 33% of the genetic variation.
