A possible signature of non-uniform Be-\alpha relationships for the
  Galaxy
  Most of the previous studies on beryllium abundances in metal-poor stars have
taken different Galactic populations as a whole when investigating the
production and evolution of Be. In this Letter, we report on the detection of
systematic differences in [\alpha/H]-A(Be) relationships between the low- and
high-\alpha\ stars which were identified by previous works. We remind that one
should be more careful in investigating the Galactic evolution of Be with a
sample comprising different Galactic populations, because such a mixed sample
may lead to inaccurate Be-Fe/Be-O relationships.
