Current efforts utilize either call–playback or autonomous recording devices, but the low detection probabilities for rails create challenges long-term systematic monitoring. Between 8 April 16 May 2022, we flew small aerial drone equipped with thermal camera six rail (Black Rail (...

The combination of PCR amplification of 16S rRNA genes with denaturing gradient gel electrophoresis (DGGE) analysis was used to reveal the compositions and dynamics of bacterial communities in a sewage treatment plant with two systems, i.e., an anoxic-anaerobic-aerobic system (inverted A20) and an anaerobic-anoxic-aerobic one (conventional A20) over a period from February to July 2009, during w...
