“…The collected samples were stored in PBS buffer. (4) Soil Samples: Soil samples were collected using the quincunx sampling method at various spaces ( Xiao et al, 2023 ), including the entrance of the poultry slaughterhouse, the slaughter workshop, and the pre-slaughter caged area. Each sample weighed 5–10 g. (5) Sludge Samples: Sludge samples were collected at the four corners of the sewage discharge pool, with approximately 10 mL of sewage collected per sample.…”

Microviridae is a family of phages with circular ssDNA genomes and they are widely found in various environments and organisms. In this study, virome techniques were employed to explore potential members of Microviridae in a poultry slaughterhouse, leading to the identification of 98 novel and complete microvirus genomes. Using a similarity clustering network classification approach, these viruses were found to belong to at least 6 new subfamilies within Microviridae and 3 higher-level taxonomic units. Genome size, GC content and genome structure of these new taxa showed evident regularities, validating the rationality of our classification method. Our method can divide microviruses into about 45 additional detailed clusters, which may serve as a new standard for classifying Microviridae members. Furthermore, by addressing the scarcity of host information for microviruses, the current study significantly broadened their host range and discovered over 20 possible new hosts, including important pathogenic bacteria such as Helicobacter pylori and Vibrio cholerae, as well as different taxa demonstrated different host specificities. The findings of this study effectively expand the diversity of the Microviridae family, providing new insights for their classification and identification. Additionally, it offers a novel perspective for monitoring and controlling pathogenic microorganisms in poultry slaughterhouse environments.

Analysis of their genomes found that the genome size, GC content and genomic structure of these new taxa showed obvious regularities, validating the rationality of our classification method. Compared with the 19 families classified by previous researchers for microviruses dataset, our method can divide microviruses into about 45 more detailed clusters, which may serve as a new standard for classifying Microviridae members. Furthermore, addressing the scarcity of host information for microviruses, this study significantly broadened their host range and discovered over 20 possible new hosts, including important pathogenic bacteria such as Helicobacter pylori and Vibrio cholerae, as well as different taxa demonstrated distinct host specificity. The findings of this study effectively expand the diversity of the Microviridae, providing new insights for their classification and identification. Additionally, it offers a fresh perspective for monitoring and controlling pathogenic microorganisms in poultry slaughterhouse environments.

To study the effect of ecological function restoration in degraded natural forests in Xiaoxinganling, Heilongjiang Province, China, we set up 90 plots of degraded natural forests of different types and ages in the Xinqing Group Branch of Yichun Forestry Industry Group in Xiaoxinganling, Heilongjiang Province, China. Moreover, 43 evaluation indexes, including litter characteristics, species diversity, soil physical properties, soil chemical properties, and canopy structural parameters, were selected to determine the effect of ecological function restoration in the degraded natural forests in the study area. Principal component analysis (PCA) was used to comprehensively evaluate the ecological function of the degraded forests. The results of the study showed that, based on the forest type scores, mixed coniferous and broadleaf forests, mixed coniferous forests, and broadleaf forests had higher scores, while the scores of pure Betula platyphylla forests, pure Larix gmelinii forests, and the three low-quality forests were lower. This showed that the ecological restoration effect for mixed forests in the Xinqing Group Branch of Yichun Sengyong Group of Xinjiangqing Group, Xiaoxinganling, Heilongjiang Province, China, was better than that for pure forests and low-quality forests. Based on forest age, the scores of near-mature forests and mature forests were generally higher than those of young forests and over-mature forests, indicating that the ecological restoration effect for near-mature forests and mature forests in Xinqing Group Branch of Yichun Forestry Industry Group in Xiaoxinganling, Heilongjiang Province, China, was better than that for young forests and over-mature forests. These evaluation results can provide a theoretical basis for subsequent research on the ecological restoration effect in degraded natural forests in Xiaoxinganling, Heilongjiang Province, China.
