Yet the “socio-ecological system” concept can be interpreted in many different ways. A characterization of the diverse practices in socio-ecological research could facilitate dialogue between researchers about the possible conceptual and ethical approaches. In this study, we investigated if a detailed analysis of scientific articles would reveal the nature and course of a socio-ecological research network, and the research angle of its members. The example we used was the Rhône River Long-Term Socio-Ecological Research (LTSER) platform in France. We combined a multivariate analysis of a reading grid of publications by Rhône River LTSER researchers and a textual analysis of the scientific narratives. The publications were from a 10-year period and corresponded to those used in a recent international comparative analysis of LTSER platforms. The analysis revealed that the research was dominated by a biophysical approach, with a progressive increase in social aspects. The emergence of a transdisciplinary approach, co-constructed with operational partners, was also shown. The research conducted by the Rhône River LTSER was grounded in the context of managing a river with strong anthropic influences and interests, and the scientific approach aimed to provide knowledge for guiding decisions. Little referencfte was made in the publications to socio-ecological conceptual frameworks. Beyond the example of this LTSER platform, we identified indicators for describing the degree of inter- and transdisciplinarity and the different perceptions of socio-ecological systems. The narrative analysis revealed the angle of the research approach; this method could be used in future studies for a comparison of the diverse approaches of multiple research groups.</p></div>","PeriodicalId":56021,"journal":{"name":"Anthropocene","volume":"45 ","pages":"Article 100412"},"PeriodicalIF":3.6,"publicationDate":"2023-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2213305423000450/pdfft?md5=fa0c278c36e4f0af3937e8bf4f7547c9&pid=1-s2.0-S2213305423000450-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135708002","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Studies have shown that multivariable agroclimatic indices can enhance climatic impact assessment on crop production. This study uses multivariable agroclimatic indices to assess how climate change may impact crop production in western Canada by the end of the 21st century. We use convection-permitting regional climate simulations for the current (CTL) and future climate under the Representative Concentration Pathway 8.5 scenario (RCP8.5) scenario based on the pseudo-global warming (PGW) approach to assess the impact of the climate on growing season indices. CTL and PGW are bias-corrected to the Global Environmental Multiscale (GEM) Canadian Precipitation Analysis (CaPA) (GEM-CaPA) dataset using the multivariate quantile mapping method. Our study analyses Effective Precipitation (Pe), Temperature Humidity Index (THI), and Precipitation Intensity Index (PII) at seasonal and sub-seasonal scales as they apply to cool-season crops. The CTL simulation shows a good performance in reproducing the spatial patterns and the temporal variability of the selected indices in western Canada. Results show that precipitation (Effective Precipitation) will decrease by over 60 mm (40 mm), rainy days will decrease by up to 10 days, and precipitation intensities will increase across western Canada. Warming will lead to THI unit increases of about 3.5 (&gt;5) in the prairies (northeastern parts of western Canada in June).

The present study was conducted in the Ladakh region of India to evaluate the socio-cultural values of the ecosystem services provided by the mountainous region.

It was observed that the respondents identified provisioning and cultural services easily compared to regulating and supporting services. Among services, fresh water and grazing services were valued 5-rating score on a Likert scale of 1–5 by more than 90% of respondents. Likewise, 80% of respondents have a 5-rating score for water retention and regulation, water purification, aesthetic and recreation and ecotourism services. A similar result was observed when the priority of ecosystem services for villagers was discussed through focus group discussions. All respondents viewed freshwater, grazing, and aesthetic services as priority ecosystem services, whereas recreation and ecotourism were prioritised in four villages, water retention and regulation, and water purification in two villages. Using bivariate correlation, the study of interactions among ecosystem services (between services of the same category) demonstrated strong positive to moderate negative correlations. Similarly, the results of the Kruskal-Wallis test indicate that socio-economic factors, including gender, income, and education, have a notable impact (p &lt; 0.05) on most of the services. This suggests that respondents' socio-economic backgrounds influence the values assigned to the services.

The predominant explanations are climate change, hunting by modern humans (<em>Homo sapiens</em>), or a combination of both. To evaluate the evidence for each hypothesis, statistical models were constructed to test the predictive power of prehistoric human and hominin presence and migration on megafauna extinction severity and on extinction bias toward larger species.
