Mental health is a crucial aspect of overall wellbeing, and anxiety and depression among graduate students have become grave concerns. This study aimed to determine whether listening to music can help graduate students to reduce their depression levels. For the experiment, 1,007 participants were selected from several universities in Guangxi, of which 56 completed the experiment. The participants were divided into a music group (n = 28) that listened to music of their choice for 30 min per week for 13 weeks and a non-music group (n = 28) that did not. After music intervention, the depression levels of the music group participants were significantly lower than that of the non-music group participants. This indicates that music has a significant effect on the depression levels of graduate students and that music could serve as an effective intervention to alleviate their depression.

Suspended solids (SS) resulting from sediment resuspension (SR) can impact ecosystems through direct and indirect effects on freshwater organisms and their interactions. This study was conducted to determine whether the SS can affect the interaction between filter-feeding fish (Aristichthys nobilis) and zooplankton using a mesocosm experiment with sediments from Lake Taihu, a large shallow lake in China. SR using pump was divided into three intensities: strong, weak and no SR representing different concentrations of SS. Zooplankton abundance was significantly higher in the no-fish treatments than in the fish treatments under all three SR conditions. SR intensity had significantly negative effect on zooplankton abundance. There were interactions between fish and SR intensity on abundances of copepod, rotifer, total zooplankton and dominant zooplankton species except cladoceran abundance. The results indicate that SS had a lesser effect on zooplankton predation by filter-feeding fish, which suggests that zooplankton communities in shallow lakes can be affected by the filter-feeding fish even under high level of SS condition.
