The elevational distributions of bacterial communities in natural mountain forests, especially along large gradients, have been studied for many years. However, the distributional patterns that underlie variations soil small-scale gradients urban ecosystems are not yet well understood. Using Illumina MiSeq DNA sequencing, we surveyed at three elevations on Zijin Mountain Nanjing City: hilltop (...

We present JHK S observations of 22 intermediate-mass stars in the Scorpius-Centaurus OB association, obtained with the NAOS/CONICA system at the ESO Very Large Telescope. This survey was performed to determine the status of (sub)stellar candidate companions of Sco OB2 member stars of spectral type A and late-B. The distinction between companions and background stars is made on the basis of a c...
