Microbial commiunity pieplot on phylum level: All samples. "others" represent the bacterial phyla with abundances of less than 0.01%.
Changes in the microbial community associated with environmental impacts can lead to opportunistic infections, coral disease and death. Diversity analysis and community comparison were performed on 23 collected soft Coral specimens from South China See surrounding Hainan Province (China) based on Illumina MiSeq sequencing. The results showed that P...

... (14.13%), Bacteroidetes (9.58%) and Acinetobacteria (8.29%) (Figure 3). After cluster analysis of each specimen, the abundance of symbiotic Proteobacteria was found to be the highest in the genus Sinularia from Dazhou Island. ...
Bacterial communities in cold-desert habitats play an important ecological role. However, the variation in bacterial diversity and community composition of the cold-desert ecosystem in Qinghai–Tibet Plateau remains unknown. To fill this scientific gape, Illumina MiSeq sequencing was performed on 15 soil samples collected from different cold-desert...
It is well concluded that microbial composition and diversity of coral species can be affected under temperature alterations. However, the interaction of environmental accumulation of corals and temperature stress on symbiotic Symbiodiniaceae and bacterial communities are rarely studied. In this study, two groups of soft coral Sarcophyton trocheliophorum were cultured under constant (26 °C) and inconstant (22 °C to 26 °C) temperature conditions for 30 days as control treatments. After that, water was cooled rapidly to decrease to 20 °C in 24 h. The results of diversity analysis showed that symbiotic Symbiodiniaceae and bacterial communities had a significant difference between the two accumulated groups. The principal coordinate analyses confirmed that symbiotic Symbiodiniaceae and bacterial communities of both control treatments were clustered into two groups. Our results evidenced that rapid cooling stress could not change symbiotic Symbiodiniaceae and bacterial communities’ composition. On the other hand, cooling stress could alter only bacterial communities in constant group. In conclusion, our study represents a clear relationship between environmental accumulation and the impact of short-term cooling stress in which microbial composition structure can be affected by early adaptation conditions.
