1 OEB 192 – 08.10.08

2 How follow diversification? MLST for Streptococcus pneumoniae (Fraser et al., 2007) (Feil, 2003)

3 Population genetic structure from MLST modest HGT high HGT (Feil, 2004)

4 MLSA in taxonomy: Burkholderia (Fraser et al., 2007)

5 Single rule may not always apply (Nesbø et al., 2006)

6 “Everything is everywhere – the environment selects.” (Baas-Becking, 1934) Microbial biogeography

7 Non-random distributions of free-living taxa (Hughes Martiny et al., 2006)

8 Biogeography: Sulfolobus (Whitaker et al., 2003)

9 Microbes in a host w/ biogeography: Helicobacter pylori (Falush et al.,2003)

10 Speciation through time
