Microbial population biology

Microbial population biology is the application of the principles of population biology to microorganisms.

Distinguishing from other biological disciplines

Microbial population biology, in practice, is the application of population ecology and population genetics toward understanding the ecology and evolution of bacteria, archaebacteria, microscopic fungi (such as yeasts), additional microscopic eukaryotes (e.g., "protozoa" and algae), and viruses.

Microbial population biology also encompasses the evolution and ecology of community interactions (community ecology) between microorganisms, including microbial coevolution and predator-prey interactions. In addition, microbial population biology considers microbial interactions with more macroscopic organisms (e.g., host-parasite interactions), though strictly this should be more from the perspective of the microscopic rather than the macroscopic organism. A good deal of microbial population biology may be described also as microbial evolutionary ecology. On the other hand, typically microbial population biologists (unlike microbial ecologists) are less concerned with questions of the role of microorganisms in ecosystem ecology, which is the study of nutrient cycling and energy movement between biotic as well as abiotic components of ecosystems.

Microbial population biology can include aspects of molecular evolution or phylogenetics. Strictly, however, these emphases should be employed toward understanding issues of microbial evolution and ecology rather than as a means of understanding more universal truths applicable to both microscopic and macroscopic organisms. The microorganisms in such endeavors consequently should be recognized as organisms rather than simply as molecular or evolutionary reductionist model systems. Thus, the study of RNA in vitro evolution is not microbial population biology and nor is the in silico generation of phylogenies of otherwise non-microbial sequences, even if aspects of either may in some (especially unintentional) manner be analogous to evolution in actual microbial populations.

Microbial population biology can (and often does) involve the testing of more-general ecological and evolutionary hypotheses. Again, it is important to retain some emphasis on the microbe since at some point this "question-driven" microbial population biology becomes instead population biology using microorganisms. Because the point of departure of these potentially disparate emphases can be somewhat arbitrary, there exist vague and not universally accepted delimits around what the discipline of microbial population biology does and does not constitute.

Microbial Population Biology Gordon conference

A Microbial Population Biology Gordon Research Conference is held every odd year, to date in New England (and usually in New Hampshire). The 2007 conference web page introduces the meetings as:

Microbial Population Biology covers a diverse range of cutting edge issues in the microbial sciences and beyond. Firmly founded in evolutionary biology and with a strongly integrative approach, past meetings have covered topics ranging from the dynamics and genetics of adaptation to the evolution of mutation rate, community ecology, evolutionary genomics, altruism, and epidemiology.

This meeting is never dull: some of the most significant and contentious issues in biology have been thrashed out here.

A history of the meeting can be found here.

The next Microbial Population Biology Gordon conference is scheduled for 2011. Information on past (and future) meetings is summarized as follows:

gollark: There are probably some jobs which work significantly better if you can physically talk to people. Although this is just a communication software problem, in many ways.
gollark: Presumably, if this was actually as productive (for normal people doing moderately boring jobs), offices would just work that way to mildly improve morale.
gollark: Alternatively, install hidden cameras in the classroom so you can monitor it at any time without leaving the comfort of your desk.
gollark: Or just refused to elaborate and remained there anyway.
gollark: You could just have explained that you were interested in concrete or something.
