Though strongly overlapping phage ecology, phage environmental microbiology considers especially the impact of environments on phages, the impact of phages on environments, and the prevalence as well as diversity of phages in those environments.     Links en.wikipedia.org/wiki/Environmental_microbiology phage.atwiki.com 2007-12-11T13:49:52+09:00 http://phage.atwiki.com/page/Bacteriophage%20evolutionary%20biology  Phage evolutionary biology studies how and why the genotypes found within phage populations change over time.   The study of phage evolutionary biology can be differentiated into a variety distinct approaches... How are phages related? Where did phages come from and how do their genomes evolve? Mechanisms of evolution (deviations from Hardy-Weinbert equilibrium) Phage evolutionary ecology   We can also consider the phage experimental evolution as a discipline which can address especially the last three approaches as listed above.     Links en.citizendium.org/wiki/Bacteriophage_experimental_evolution phage.org   Internal hierarchy phage.atwiki.com bacteriophage evolutionary biology 2007-12-02T19:31:47+09:00 http://phage.atwiki.com/page/Bacteriophage%20ecology     Links en.wikipedia.org/wiki/Bacteriophage_ecology phage.org phage.atwiki.com 2007-12-02T19:26:23+09:00 http://phage.atwiki.com/page/FrontPage Wiki is a type of websites.
