The pterosaur collection at the natural history museum is of great historical importance. Most of the material is figured or cited, and several specimens are types or casts of types. Pterosaurs from UK localities are well represented, but foreign material is also present as original specimens and as high quality casts. The entire collection has been recorded in a database and curatorial improvements have been made, which has improved physical and virtual access to the collection. Although many of the specimens were collected as long ago as the early 1800s, they are still useful today. A full list of natural history museum pterosaur specimens is published, for the first time since 1888.

The Hakka people, a branch of the Han ethnic group with their own language, culture, and customs, are one of the largest immigrant groups worldwide, primarily distributed in southern China. Bobai, a county with the largest Hakka population globally, has a thriving weaving industry that is one of the local pillar industries. This study aimed to systematically analyze the plant source, product function, and development model of Bobai Hakka weaving. The study recorded 33 plant species for weaving, which belonged to 17 families and 27 genera. The weaving plants were mainly bamboo, rattan, herbs, and wood, with herbs being the most commonly used(15 species, 45.5%). Most weaving plants were obtained locally(16 species, 48.5%) and from wild sources(13 species, 39.4%). Stems were the most commonly used plant parts(66.7%) in local weaving, followed by leaf sheaths, inflorescence stems, leaves, stem bark, leaf rachis, and female bracts. Additionally, wastes from crops such as wheat, rice, bananas, and corn, as well as invasive water hyacinths, were widely used as weaving materials by the local Hakka people. The products 'functions ranged from household appliances, cultural and entertainment products, furniture, to production tools, reflecting a range of conventional cultural connotations. The study found that the Bobai Hakka weaving industry had integrated modern elements and additional use value to expand its market appeal. With the participation of the government, enterprises, and farmers, the Bobai weaving industry has formed a development model of “ intangible cultural heritage+industry+poverty alleviation ”, which has become a successful case of poverty alleviation and rural revitalization.

Background: The Luchuan pig is an indigenous breed from Luchuan County, China, with cultural and genetic significance. However, traditional knowledge and conservation status have not been systematically documented. Methods: Using ethnobiological methods, we surveyed 72 Luchuan pig farmers in 7 townships during 2021-2023. Semi-structured interviews and participant observation were conducted to document traditional knowledge and management practices. Results: The locals reported 51 plant species used as pig feed, with 30 wild species. Growth-stage-specific feeding and seasonal adjustment practices were documented. We recorded 62 ethnoveterinary plant uses, mainly for treating pigs ' heat stress and skin conditions. Luchuan pigs play central roles in local Hakka customs, rituals, and cuisine. Additionally, the new ecological farming models minimize the environmental impacts to the local community. However, there are still some challenges remained for conserving and promoting Luchuan pigs. Conclusions: The Luchuan Hakka people possess rich traditional knowledge and management experience in raising Luchuan pigs. Our study provides extensive documentation of traditional knowledge and recommends integrating cultural and genetic aspects for sustaining this biocultural heritage. Findings can inform initiatives supporting local breed conservation globally.

Odorrana lipuensis occurs in an entirely dark karst cave in Lipu County, guangxi Zhuang Autonomous Region, China. This paper discusses the ecological habits of the type locality of O. lipuensis, including the cave environment, daily activity rhythm, annual activity pattern, food, and predators. The results show that the life cycle of O. lipuensis is completed entirely in dark caves; cave temperature fluctuates around 19 ℃; there is no hibernation phenomenon, and it is active throughout the year. The daily activity rhythm does not differ between day and night, and breeding seasons range from March to June. Given the limited distribution range and small population size of O. lipuensis, it is recommended for inclusion in the national second-class protection animal list.
