Here, we simultaneously study the phase-space distribution and the main characteristics of Virgo's galaxies, particularly its most abundant galaxy population - the early-type dwarfs - to understand their environmental transformation histories. Aside from known correlations with morphological types - like the larger average clustercentric distance of late-type galaxies - we find an intriguing behavior of early types with magnitudes -17 >= M_r >= -18. They show a large velocity spread and an ","authors_text":"Christoph Engler, Joachim Janz, John S.
