This allows interrogation of the genome content of bacterial strains from a variety of sources, environments and disease states, and the identification of genetic markers that may explain how different strains are adapted to their respective niches or disease capability.
The results are consistent with the idea that listeners perceptually separate sound sources from reverberation, constrained by the likelihood of source-environment pairings.
For populations under the combined antibiotic phage treatment, we considered two types of source environments: 0.1 KB and the phage-treatment environment.
One practical advantage of genecology studies is the ability to evaluate a large number of populations from a wide range of source environments in one or a few easily accessible common gardens.
Besides the number of sources, the environment and the type of signals also play a major role in our synthesis method.
While these findings are consistent with a role of source country environment, they could plausibly result either from the effect of culture or social capital.
To distinguish between the two, we turn to the distinction discussed earlier that culture represents an impact of source country environment on beliefs or preferences, and social capital represents an impact on productivity or wages.
Natural selection is suggested when populations differ in putative adaptive traits, those differences are correlated with characteristics of the source environments, and the relationship between a trait and an environmental character is logical for growth, survival, or reproduction.
This is consistent with the sample source environment of human saliva, which has a high possibility of containing human DNA.
But in Australia, O'Brien said people could be exposed to the bacteria through a variety of sources in the environment, for example the soil.
