Boots M., A. White, A. Best, and R. Bowers. 2014. How specificity and epidemiology drive the coevolution of static trait diversity in hosts and parasites. Evolution. doi: 10.1111/evo.12393

We examine theoretically how epidemiological feedbacks and the characteristics of the interaction between host types and parasites strains determine the coevolution of host–parasite diversity.

When challenged with flatulogenic diet, patients’ microbiota developed instability in composition, exhibiting variations in the main phyla and reduction of microbial diversity, whereas healthy subjects’ microbiota were stable. Taxa from Bacteroides fragilis or Bilophila wadsworthia correlated with number of gas evacuations or volume of gas evacuated, respectively.

“I’ve developed a data scraper that gathers information on student dissertations, such as page length, year and month of graduation, major, and primary advisor.”

“I hate the phrase next-generation sequencing (NGS) with a passion. Here’s why …” [Plus addendum.]
