post hoc test - (May/03/2010 )

Hi,
Can anyone explain me why there are many tests (Duncan, Tukey, Bonferroni etc.,) for Post hoc analysis??? Which one is most suitable for biological research?
I could find Duncan's post hoc in majority of research articles, while few were used Tukey's...?

They each are derived a little differently, some are more conservative than others. Usually, it's personal preference.
