Summary: Two new species of Antrodia, A. aridula and A. variispora, were discovered in western China. Phylogenetic analysis based on a six-gene dataset showed that these two species form independent lineages within the Antrodia clade and have distinct morphological characteristics from other known Antrodia species. A. aridula is characterized by angular to irregular pores of 2-3 mm and oblong ellipsoid to cylindrical basidiospores measuring 9-12 x 4.2-5.3 μm, while A. variispora has sinuous or dentate pores of 1-1.5 mm and oblong ellipsoid, fusiform, pyriform, or cylindrical basidiospores measuring 11.5-16 x 4.5-5.5 μm, and they grow on different types of wood.

Summary: This study assessed the predatory and nematocidal activities of the fungus Arthrobotrys musiformis against the parasite Haemonchus contortus. Liquid culture filtrates of the fungus were found to have high predatory and nematocidal activities, with a larval reduction of 71.54% and a high nematocidal activity in Czapek-Dox broth. The mycochemical profile analysis identified alkaloids and saponins in both media, and coumarins only in Czapek-Dox broth.

Summary: This study utilized leaves as island models to assess microbial biodiversity, revealing significant microbial SAR in deciduous trees but not in evergreen trees. There were no significant differences in microbial diversity at the alpha diversity level, but significant differences were observed in beta diversity. Consistent historical background may mask microbial SAR, highlighting the importance of intensive sampling and consistent historical background for understanding microbial SAR.

Summary: This study investigated the effect of mesenchymal stem cells (MSCs) and tanshinone IIA on Alzheimer's disease (AD) and oxidative stress. The results showed that the injection of MSCs (tanshinone IIA) into the hippocampus improved learning and memory deficits, reduced neuronal injury, suppressed oxidative stress, and attenuated Aβ accumulation and Tau hyperphosphorylation in AD rats. The transplantation of MSCs (tanshinone IIA) may be a potential therapeutic approach for AD by inhibiting oxidative stress.

Summary: High voltage cable is crucial for power transmission, and polypropylene is commonly used as the insulation material due to its excellent heat resistance, insulation, and environmental friendliness. The insulation material needs to withstand pulsed and DC rated voltages, which can cause distortion of the electric field and accumulation of space charge. It is necessary to regulate the electric field in order to suppress degradation phenomena. This work introduces the theory and method of regulating the DC electric field of polypropylene insulation for high voltage cable, presents the main direction of electric field regulation, and discusses the application prospect of polypropylene cable insulation.

Summary: Dispersal is a key process in determining biodiversity. The passive sampling hypothesis suggests that larger habitats receive more species from the species pool, resulting in higher species richness compared to smaller habitats. This study used a designed experiment to test the passive sampling hypothesis and found that larger filter paper received more colonists, confirming the species-area relationship. Dispersal shaped biodiversity patterns by increasing species richness, especially of rare species, and promoting species replacement between habitats.

Summary: The existence of biogeography for microorganisms is a hot topic in ecology, and researchers are using better distinction methods to reveal potential hidden patterns. In this study, a group of soil nematode-trapping fungi were analyzed to gain insight into the geographic distribution of microorganisms. The results showed a cosmopolitan tendency for this group, with only a few widespread species and non-random heterogeneous distributions for the others. The study highlights the need for further research on factors influencing microbial distribution.

Summary: Traditional zooarchaeological and archaeobotanical methods rely on morphological identification of remains, but sedimentary ancient DNA (sedaDNA) offers a new approach by sequencing ancient DNA. In this study, sedaDNA shotgun metagenomics was applied on archaeological deposits, showing consistent results with traditional methods for crops and domestic animals, and detecting additional species and microorganisms. The combined approaches revealed diversified food resources at the site, laying the foundation for broader applications of sedaDNA in faunal and floral reconstruction.

Summary: During the investigation of nematode-trapping fungi in Yunnan Province, two new Arthrobotrys species were identified based on morphology and multigene phylogenetic analysis. Arthrobotrys gongshanensis is characterized by conidiophores producing short denticles near the apex, bearing a single conidium on each denticle, and obovoid to fusiform, 1-4-septate conidia. Arthrobotrys luzhangensis is characterized by its obovoid to fusiform, 1-4-septate macroconidia, and clavate or obovoid, aseptate microconidia. These two new species both capture nematodes using adhesive networks. The taxonomic positions of these species within Arthrobotrys were confirmed by multigene phylogenetic analysis.

Summary: This study investigates the biogeographical patterns of Arthrobotrys oligospora, the most widespread globally distributed nematode-trapping fungi (NTF), in Yunnan Province, China. The results show that A. oligospora is randomly distributed throughout Yunnan Province at the population level, while at the genetic level, it diverges into five major evolutionary clades with a low degree of gene flow between them. The distribution of these clades is highly consistent with the watersheds distribution, suggesting that watersheds play a key role in the biogeographic distribution patterns of A. oligospora.

Summary: In this study, a new method for the identification of dormant microorganisms based on high-throughput sequencing technology called Revived Amplicon sequence variants (ASV) Monitoring (RAM) was proposed. It was found that RAM was able to better identify dormant microorganisms compared to the currently used gene function prediction (GFP) method. The results from both methods showed a four-stage distribution pattern over a 60-day period, indicating significant differences in the community structure of dormant microorganisms.
