A. [8pts] Briefly explain why members of the phyla Firmicutes and Actinobacteria increased in relative abundance in soils following a forest fire in Four Mile Canyon (see graph comparing burned and unburned soils, 4 weeks after the fire). Be sure and mention a trait (that is structures they produce or functions they carry out) of members of each phylum that help explain the data. B. [4.5pts] Name a genus from each phylum that you might expect to encounter in the burnt soils. 100 75 Percentage of community 50 Others Bacteroidetes Acidobacteria Betaproteobacteria Alphaproteobacteria Firmicutes Actinobacteria 25 0 Unburned Burned Briefly describe an experimental approach that would be more successful in culturing bacteria from a marine, freshwater OR soil environment in which it has previously been difficult to culture bacteria. In your answer, include (you may write your answers as a bulleted list): 1. The type of environment (soil, marine, river, lake). II. [6pts] Your hypothesis/prediction as to why the bacteria did not grow in culture in the lab previously. III. [6pts] Your experimental set-up: what would you do to try and grow previously uncultured bacteria. IV. [3pts] Your expected result: what do you expect to find at the end of the experiment.
