Based on the Stable Ecotype Model, evolution leads to the divergence of ecologically distinct populations (e.g., with different niches and/or behaviors) of ecologically interchangeable membership. In this study, pyrosequencing was used to provide deep sequence coverage of Synechococcus psaA genes (encoding a photosystem I reaction center protein subunit) and transcripts over a large number of habitat types in the Mushroom Spring microbial mat. Putative ecological species (putative ecotypes), which were predicted by an evolutionary simulation based on the Stable Ecotype Model (Ecotype Simulation), exhibited distinct distributions relative to temperature-defined positions in the effluent channel and vertical position in the upper …

Herbert W. Conn: Formative Decades Of Microbiology And Evolutionary Biology, Frederick M. Cohan, Alexa Boesel
Frederick M. Cohan
Herbert W. Conn (1859–1917) made outstanding contributions to both microbiology and evolutionary biology, reflecting his intellectual command of several biological disciplines. Conn endeavored to make the unseen world of microbes familiar, real, and consequential to members of the general public. He presciently considered the role of bacteria in our own bodies, describing them as being both harmful and beneficial to our health. He also contributed to our understanding of the concept of species, how they originate, and what those ideas might mean in terms of bacterial speciation. In Conn’s spirit, microbial ecologists studying speciation eschew the “species” taxa of bacterial …

Identification of closely related, ecologically distinct populations of bacteria would benefit microbiologists working in many fields including systematics, epidemiology and biotechnology. Several laboratories have recently developed algorithms aimed at demarcating such ‘ecotypes’. We examine the ability of four of these algorithms to correctly identify ecotypes from sequence data. We tested the algorithms on synthetic sequences, with known history and habitat associations, generated under the stable ecotype model and on data from Bacillus strains isolated from Death Valley where previous work has confirmed the existence of multiple ecotypes. We found that one of the algorithms (ecotype simulation) performs significantly better than …
