is a well-known conifer pest that has contributed significantly to spruce forest disturbance in the Qinghai-Tibet Plateau and seriously threatens ecological balance of these areas. We report chromosome-level genome

Globally, forest decline and tree mortality are rising due to climate change. As one of the important afforestation trees in northeast China, Pinus sylvestris var. mongolica is suffering from accompanying pests. Certain fungi ophiostomatalean contribute pest outbreaks can be pathogenic pine trees. However, only a limited number associated with beetles infesting have been identified. In this study, 293 were isolated Acanthocinus griseus, Ips chinensis, Pissodes nitidus Heilongjiang Province,...

Ips (Curculionidae: Scolytinae) bark beetles (BBs) are ecologically and economically devastating coniferous pests in the Northern Hemisphere. Although microbial diversity associated with these has been well studied, mechanisms of community assembly functional roles key microbes remain poorly understood. This study investigates structures functions both intestinal non-intestinal environments five BBs using a metagenomic approach. The findings reveal similar compositions, though α-diversity...

Bark beetles and their associated fungi, which cause forest decline sometimes high mortality in large areas around the world, are of increasing concern terms health. Three Tomicus spp. (T.brevipilosus, T.minor T.yunnanensis) infect branches trunks Pinusyunnanensis P.kesiya Yunnan Province, south-western China. well known as vectors ophiostomatoid fungi co-occurrence could result serious ecological economic impact on local ecosystems. Nonetheless, knowledge about diversity, ecology, including...

Abstract Ips subelongatus is a major pest that infects larch plantations over large areas of northern and northeastern China. species are closely associated with ophiostomatoid fungi morphologically well-adapted for dispersal by beetles. These associations result in important threat coniferous forests worldwide. The aim this study was to characterize the communities I. infesting Larix sympatric Pinus sylvestris var. mongolica China forests. Morphological multilocus phylogenetic approaches...

We report the discovery of a fossil agaricoid homobasidiomycete from Dominican amber (ca 15-20 Ma). Aureofungus yaniguaensis appears to be member euagarics clade, but its precise taxonomic placement is obscure. This fourth known agaric and third amber.

Climate change has exacerbated outbreaks of forest pests worldwide. In recent years, bark beetles have caused significant damage to coniferous forests the Northern Hemisphere.

Pine wilt disease (PWD) is a devastating that occurs worldwide and affects conifers infested by the pine wood nematode (PWN, Bursaphelenchus xylophilus). PWD has caused serious economic ecological losses in China. The mechanism of outbreak complex, with associated fungi, specifically ophiostomatoid thought to play an essential role. However, few fungal associates have been accurately identified. In present study, we isolated fungi from bark beetles collected Pinus thunbergii on Laoshan...

The role of several virulent tree pathogens in host death has been overlooked because the aggressiveness their associated bark beetles. great spruce beetle (Dendroctonus micans) is a widely distributed that infests coniferous plants Eurasia; however, its fungi have poorly studied. Therefore, this study, we elucidated diversity ophiostomatoid with D. micans northeastern Qinghai-Tibet Plateau through field investigation, laboratory isolation, and culture analyses. A total 220 strains were...

Forest disturbance and recovery detection is vital for assessing ecosystem resilience service to further establish the sustainable development. Time series analyses of remote sensing data provide essential effective methods in such research. Some studies have incorporated spatial structural characteristics improve accuracy detecting forest abrupt disturbances, however, few them paid attention during dynamics. To more comprehensively detect explore effectiveness incorporating metrics dense...

As a severe invasive pest, red imported fire ant (Solenopsis invicta Buren) had important effects on ecosystem of its infected areas. Here, we surveyed impact S. populations two banana insect pests, skipper (Erion tatorus Evans) and stephanitis (Stephanitis typical Distant). The results showed that influences population E. depend weed coverage degree plantations. Comparing to the areas without invicta, was reduced by 39.2%, 41.4% 23.4% respectively, in high, moderate low plantations with...

Ophiostomatoid fungi are known for their associations with bark beetles, and some species important sources of tree diseases. Ceratocystiopsis is a genus the ophiostomatoid in order Ophiostomatales. The shortage DNA barcodes many this has resulted presence unnamed cryptic species. In study, subelongati sp. nov. associated Ips subelongatus infesting Pinus sylvestris var. mongolica Inner Mongolia, China, was identified described based on phylogenetic inference multi-gene sequences...

Species of the genus Foenobethylus Kieffer, 1913 are parasitoids wasps rarely collected and only found in Oriental region. In this study, based on both morphological molecular evidence, we describe three new species from China: F. robusta Li & Chen, sp. nov. , xinglongsensis Wang yunkaishanensis Chen Luo, An updated key to is provided. Additionally, phylogenetic relationships between other morphologically similar genera discussed analyses COI 28S genes.

Kalimeris integrifolia)的化学成分进行研究, 从其地上部分的乙醇提取物中 分离得到两个化合物, 应用 HR-ESIMS, 1D 和 2D NMR, IR, UV 等多种波谱技术确定了化合物的化学结构, 经鉴定分别 为 5,8-二羟基-2-(3-羟基-4,5-二甲氧苯基)-6,7-二甲氧基-4H-色烯-4-酮(1)和 5-羟基

Abstract Improving health of Chinese people has become national strategy according to the Healthy China 2030. Patient experience evaluation examines care service from perspective patients; it is important for improving quality. Applying artificial intelligence (AI) in patient an innovative approach assist continuous improvement quality service. A nursing platform based on data which empowered by AI technologies been established purpose surveillance and analysis care. It contains nearly 1300...
