The aim of this work is to examine the environmental
dependence of stellar velocity dispersion in local
galaxies. In studies that likely suffer from the radial selection
effect, one has a preference for the use of volumelimited
samples. Two volume-limited samples with different
redshift and luminosity ranges were constructed from
the Main galaxy data of the Sloan Digital Sky Survey Data
Release 10 (SDSS DR10). Considering some drawbacks of
volume-limited samples, the apparent magnitude-limited
Main galaxy sample was also applied. Statistical analyses
in these different galaxy samples can reach the same conclusion:
galaxies with large stellar velocity dispersions exist
preferentially in high density regimes, while galaxies
with small stellar velocity dispersions are located preferentially
in low density regions, which is inconsistent with
that obtained at intermediate redshifts.
