Forest ecosystems are strongly impacted by extreme climate, and the age effects of radial growth under drought can provide profound understanding of the adaptation strategy of a tree species to climate change. Schrenk spruce (Picea schrenkiana Fisch. & C.A. Mey) trees of three age groups (young, middle-aged, and old) were collected to establish the tree-ring width chronologies in the eastern Tianshan Mountains of northwestern China. Meanwhile, we analyzed and compared the response and resistance disparities of radial growth to drought in trees of different age groups. The results showed that (1) drought stress caused by increasing temperatures was the main factor limiting the radial growth of Schrenk spruce, (2) the old and young trees were more susceptible to drought stress than the middle-aged trees, as suggested by the responses of Schrenk spruce trees and based on the SPEI (standardized precipitation evapotranspiration index), and (3) the difference of the resistance indexes (resistance, recovery, resilience, and relative resilience) of three age groups to drought supported that the resistance values were in the order middle age > young age > old age, but the recovery, resilience, and relative resilience values were in the order old age > young age > middle age. These results will provide a basis for the ecological restoration and scientific management of dominant coniferous tree species of different age groups in the sub-alpine forest ecosystems of the arid regions under climate change scenarios.

Images Of The Future

Abstract Background Adolescents' images of the future emerge from knowledge built on experiences of the past and present and their age-related developmental tasks. Images of the future direct adolescents' decision-making, choices, and behavior. The images of the future can act as a mirror of our times, reflecting the political values and ethos of society. The aim of this study was to examine the fears for the future among Finnish adolescents in the era of climate change. Methods Data from a nationwide survey on the health and health behavior of 12-, 14-, 16-, and 18-year-olds (n = 3520, the response rate 37 %) in 2019 in Finland. An open-ended question on fears for the future was employed as a final question on the survey. The data was analyzed first by inductive content analysis and then by statistical methods. Altogether 7829 fears were reported. These were constructed into 12 main categories. Results Fears for the social relationships and loneliness were the most common (35 %). Fears related to death (33 %), physical health and wellbeing (25 %), life management and success (19 %) and working life (17 %) were next common. Only 9 % of the adolescents reported climate and the environment related fears. In age group comparisons, 12-14-year-olds reported more global and social fears, while 16-18-year-olds reported more personal fears, such as study, working life and relationships. The most common fears among boys and girls were similar in all age groups. Conclusions The most common fears among Finnish adolescents are related to personal life and less to global issues. Against our hypothesis, climate and environmental related fears were not among the top fears, even these topics are figured prominently in media and other research has also reported high proportions of climate change related fears among adolescents. The inconsistencies might be explained by the differences in the research methodologies: whether open-ended questions or structured questions are used. Key messages Most common fears for the future are related to personal issues like relationships, health and work. Fears for climate change were not among the most common ones when open-ended questions were used.
