Gram+ Actinbacteria, forms mycelium and dessication resistant spores - Thomas Sharpton

High amoung of horizontal DNA exchange. - Thomas Sharpton

Introducing everything is everywhere, habitat filtering, and dispersal limitation and regional diversification hypotheses - Thomas Sharpton

Isolated 924 strains from 15 sites across the US. 4 soil variables (pH, moisture, temperature, soil order) , rpoB gene analysis - Thomas Sharpton

Using tool called AdaptML. from the Alm lab: http://almlab.mit.edu/ALM... - Thomas Sharpton

Regional populations differ in the representation of various strains - Thomas Sharpton

Therefore, everything is NOT everywhere - Thomas Sharpton

Phylogenetic clustering of various sites indicates habitat filtering or dispersal limitation and regional diversification - Thomas Sharpton

Genetic differentiation is positively associated with geographic distance, number of shared sequences between sites decay with distance. This suggests that habitat filtering is not valid. - Thomas Sharpton

Using haplotype analyses to evaluate the expansion of strains throughout the US and understand their biogeography - Thomas Sharpton

Hypothesizes that glacial retreat influenced the ecological evolution of soil bacteria, enabling their rapid expansion - Thomas Sharpton

// I went to a microbial ecology talk just a couple of years ago where the presenter very hesitantly suggested that everything might not be everywhere, as if it were a heresy... - Ruchira S. Datta

@Ruchira - Funny how things change (quickly). This conference may not have killed baas-becking, but certainly raises doubt about that hypothesis - Thomas Sharpton
