Abstract

Geographical names and the entities they represent act as a fundamental cornerstone across numerous disciplines. However, inconsistent geographical names and arbitrarily defined regional geographical scales are common, hindering cross-disciplinary communication and synthesis. The Pan-Tibetan Highlands, comprising the Tibetan Plateau, Himalaya, Hengduan Mountains and Mountains of Central Asia, is a case in point. To rectify these inconsistencies of terminology, we employed a multi-disciplinary approach to standardize the nomenclature of the Tibetan Plateau and the three adjacent mountain regions, defining their spatial extent using historical and contemporary perspectives. A literature meta-analysis indicated that ‘Tibetan Plateau’, ‘Himalaya’ and ‘Hengduan Mountains’ are the most suitable names for these regions in terms of both priority (earliest use) and popularity, whereas ‘Mountains of Central Asia’ emerges as appropriate for the mountain chains to the west of the Tibetan Plateau. The new term ‘Pan-Tibetan Highlands’ is proposed to replace the less precise and arguably misleading ‘High Mountain Asia’ for these regions collectively. Additionally, new geographical boundaries, applicable back through time, are proposed for each region, based on geological and geomorphological features. Using these new boundaries, the Pan-Tibetan Highlands area is 3.95 × 106 km2 with a mean elevation of 3,824 m, while the Tibetan Plateau is smaller (1.82 × 106 km2) and higher (4,465 m) than commonly assumed. Across the Pan-Tibetan Highlands, the proportion of protected areas is be far below the proposed 30% anticipated in the post-2020 Global Biodiversity Framework target with only a few exceptions. Additionally, the Hengduan Mountains showed the highest vascular plant species richness and endemism, followed by the Himalaya, Mountains of Central Asia and Tibetan Plateau. The obvious conservation gap in the Pan-Tibetan Highlands calls for urgent research-based optimization of conservation network. Our approach benefits quantitative spatial analysis by providing well-defined geographical scales for various fields, aiding cross-disciplinary comparisons and synthesis.

Abstract

In 1958, Chun and Kuang described Cathaya Chun & Kuang as a new genus of Pinaceae. They included one fossil species, C. loehri (Engelh. & Kink.) Chun & Kuang and two extant species, C. argyrophylla Chun & Kuang and C. nanchuanensis Chun & Kuang. Under Art. 40.1 of the Shenzhen Code, they did not validly publish Cathaya because they did not designate a type species for the generic name. Four years later (Chun and Kuang 1962), they again published on Cathaya (in Chinese) where they cited the 1958 publication and included one species C. argyrophylla (with C. nanchuanensis in synonymy) under Cathaya. According to Art. 40.3, they validated both the generic name Cathaya and C. argyrophylla in 1962. Further examination of the type collection and botanical history of the discovery of C. argyrophylla revealed that the type collection Guang-Fu-Lin-Qu Exped. 00198 consists of 11 duplicates in the South China Institute of Botany (IBSC) and 9 duplicates in other herbaria (GAC, IBK, PE, SZ) and that the intended type specimen (IBSC0000004) consists of two gatherings: the bark, reproductive shoot and seed cones collected in 1955, whereas pollen-bearing cones were collected in 1956. We thus lectotypify the name C. argyrophylla with the specimen Guang-Fu-Lin-Qu Exped. 00198 (IBSC0000004 excl. pollen-bearing cones). [ABSTRACT FROM AUTHOR]
