Historical temperature reconstructions at high altitudes are still insufficient in southwestern China, which is considered one of the most sensitive areas to climate change in the world. Here we developed a tree ring-width chronology of Faxon fir Abies fargesii var. faxoniana at the upper timber line on Zhegu Mountain, Miyaluo Scenic Area, western Sichuan, China. The climate-tree growth relationship analysis indicated temperature as the dominant regulator on radial tree growth in this region. The reconstruction of aggregated maximum temperature (TMX) of autumn and winter for the period 1856-2016 was achieved with a linear regression model that accounted for 43.6% of the actual variability in the common time series (1954-2016). The reconstruction identified 4 warm periods and 3 cold periods. Similarities of warm and cold periods with previously published reconstructions from nearby sites indicated the reliability of our reconstruction. The significant positive correlation between TMX reconstruction and the Asian-Pacific Oscillation index and the Atlantic Multi-decadal Oscillation index suggested a linkage between large-scale climate circulations and the thermal variability at a multi-decadal scale on the western Sichuan Plateau. We also found that solar activity exerted a strong influence on decadal temperature variability in this region. The cold periods were matched well with historical large volcanic eruptions. Our results strengthen the historical climatic information in southwestern China and contribute to further understanding the regional thermal variability as well as its driving mechanism.

The diversity of the ‘Pselaphodes complex’ of genera from Asia remains fragmentally documented. Herein we describe fifteen new species of the genus Labomimus Sharp from China: L. assingi sp. nov. and L. dilatatus sp. nov. from Shaanxi, L. longnan sp. nov. and L. minshanus sp. nov. from Gansu, L. chouwenii sp. nov. from Taiwan, L. yue sp. nov. from Guangdong, L. howaichuni sp. nov. from Hong Kong, L. jinfomontis sp. nov. from Chongqing, L. niger sp. nov. from Sichuan, L. maolan sp. nov. from Guizhou, L. corpulentus sp. nov., L. dulongensis sp. nov., and L. wuchaoi sp. nov. from Yunnan, and L. medogensis sp. nov. and L. qiujianyuae sp. nov. from Xizang. A little known species, L. torticornis (Champion), originally described from Assam, northeastern India, is newly recorded in Yunnan, southwestern China. Illustrations of the habitus and major diagnostic characters of all treated species are provided. A checklist and a distributional map of world species are given.

Barriers And Challenges

Abstract Background With the development of digital media, online activities are increasingly becoming part of the daily life of older adults. Widowed older adults generally would face changes in social interactions and activities due to widowhood; thus, the importance of online participation may be more prominent in this population. However, a detailed evidence on the experiences of online social participation among widowed older adults is relatively sparse. This study aimed to explore widowed older adults’ perceptions regarding online social participation in southwestern China. Methods This study adopted a qualitative approach. Semi-structured, in-depth individual interviews were conducted with 19 widowed older adults between September–December 2020. Thematic analysis was applied to analyse the data. Results Two major themes, “benefits” and “barriers” were identified from the original data analysis. Subcategories concerning the theme “benefits” were “benefit perception (convenience, flexible time, supplementation)”, “health promotion”, “emotional comfort”, and “social connection”. Subcategories of “barriers” were “worries: personal economic loss”, “concerns: security of digital device”, “troubles: the diversity of online social participation”, and “difficulties: using digital media”. Conclusions Social participation of widowed older adults in southwestern China has begun to be integrated into the digital world; however, it remains at an early stage with the simple purpose of engagement. The older adults may face many challenges for online social participation. Although there are barriers and challenges in online social participation, widowed older adults can reap its benefits, which can be used as an important measure to facilitate a fulfilling life and successful ageing. There is no doubt that online social participation will become a trend within the foreseeable future. Family, friends and health care professionals should pay more attention to the needs of online social participation in widowed older adults and provide adequate support for them to achieve a meaningful life.
