Studying the attention of “artificial intelligence + education” in ethnic areas is of great significance for China for promoting the integrated development of new educational modes and modern technology in the western region. Guizhou province is an area inhabited by ethnic minorities, located in the heart of Southwest China. The development of its intelligent education has strong enlightenment for the whole country and the region. Therefore, this paper selects the Baidu Index of “artificial intelligence (AI) + education” in Guizhou province from 2013 to 2020, analyzes the spatial–temporal characteristics of its network attention by using the elastic coefficient method, and builds the ARIMA model on this basis to predict future development. The results show that the public’s attention to “AI + education” differs significantly in time and space. Then, according to the prediction results, this paper puts forward relevant suggestions for the country to promote the sustainable development of education in western ethnic areas.

Nowadays, the global fish consumption continues to rise along with the continuous growth of the population, which has led to the dilemma of overfishing of fishery resources. Especially high-value fish that are overfished are often replaced by other fish. Therefore, the accurate identification of fish products in the market is a problem worthy of attention. In this study, full-DNA barcoding (FDB) and mini-DNA barcoding (MDB) used to detect the fraud of fish products in Guiyang, Guizhou province in China. The molecular identification results showed that 39 of the 191 samples were not consistent with the labels. The mislabelling of fish products for fresh, frozen, cooked and canned were 11.70%, 20.00%, 34.09% and 50.00%, respectively. The average kimura 2 parameter distances of MDB within species and genera were 0.27% and 5.41%, respectively; while average distances of FDB were 0.17% within species and 6.17% within genera. In this study, commercial fraud is noticeable, most of the high-priced fish were replaced of low-priced fish with a similar feature. Our study indicated that DNA barcoding is a valid tool for the identification of fish products and that it allows an idea of conservation and monitoring efforts, while confirming the MDB as a reliable tool for fish products.

Some new information of A. reflexus Uéno, 2006 is provided, including the male genital characteristics as well as a new locality. Two new species are described and illustrated from southwestern Guizhou Province, southwest China: A. xiongda n. sp. (Guizhou: Anlong: Fengyan Dong), A. dudou n. sp. (Guizhou: Xingyi: Xiaozi Dong). A key to all Aspidaphaenops species is also provided.

Two new species of Lohmanniidae, Papillacarus (Papillacarus) retinervius sp. nov. from soil in Hainan Province, South China and Papillacarus (Papillacarus) mammilatus sp. nov. from moss and soil in Guizhou Province, Southwest China are described and illustrated. Papillacarus (P.) retinervius sp. nov. is most similar to Papillacarus (P.) polygonatus (Ermilov & Anichkin, 2011), however, it can be distinguished from the latter by the following characterstics: 20–21 pairs of additional neotrichal setae, setae d2, e2, h1, p1 shorter, as long as d1, epimeral setal formula 10-8-4-3. Papillacarus (P.) mammilatus sp. nov. is most similar to Papillacarus (P.) angulatus (Wallwork, 1962), however, it can be distinguished from the latter by the following characterstics: transverse bands S3 complete, eight pairs of subcapitular setae, epimeral setal formula 10-6-3-4.

New Distribution

A new fern species, Polystichum alluvium, a member of P. subg. Haplopolystichum (Dryopteridaceae), is described from Guizhou Province in Southwest China. Polystichum alluvium is similar to P. lanceolatum in having small habit and subcoriaceous pinnae, but the former has oblanceolate laminae with basal pinnae strongly contracted toward lamina base, deltoid-ovate and sessile pinnae, and very short spinules on acroscopic pinna margins or no spinules, while the latter has lanceolate laminae with basal pinnae not contracted toward lamina base, oblong and petiolate pinnae, and long spinules on acroscopic pinna margins. Polystichum alluvium was found from the alluvial bottom of a karst cave at an elevation of 1410 m with humid and shady conditions and is currently known from one population with ca. 50 plants in western Guizhou. It is classified as Critically Endangered (CR) following IUCN Red List criteria. We also expanded the distribution of P. leveillei to southern-central Guizhou based on our new collections.
