Characterization and discrimination of tundra plant leaves by Attenuated Total Reflection Fourier transform infrared spectroscopy
No full textAttenuated total reflection Fourier transform infrared (ATR-FTIR) spectroscopy is a powerful tool for investigating the biochemical fingerprint of plants, but its applicability to tundra plant leaves has yet to be addressed. The present study aimed to apply ATR-FTIR measurement to characterize tundra plant leaves and to discriminate these among plant species with different growth forms. The ATR-FTIR spectra in the fingerprint region (1800–800 cm–1) of live and dead leaves from 14 tundra plant species of shrubs, forbs, graminoids, and mosses showed a variability in overall appearance among plant species and a degree of similarity between live and dead leaves of the same plant species. Four highest peaks were found at 1637–1575 cm–1, 1452–1406 cm–1, 1325–1313 cm–1, and 1058–1022 cm–1 in these spectra and are attributed to chemical features of lignin, cellulose, and/or oxalate. Principal component analyses showed that leaves of Oxyria digyna and other forbs had distinctive spectral characteristics attributable to the content of oxalate and other putative compounds and that contents of lignin relative to cellulose were generally greater in shrubs than in graminoids and mosses. These results demonstrated that ATR-FTIR spectroscopy is useful for future applications in polar biology and ecology, for example the description of functional traits of arctic plants and decomposition processes by microbes.journal articl
Cross-cultural visual anthropology: Beyond repatriation, exploring indigenous and non-indigenous exchanges
No full textCollaboration is critical concept in Arctic anthropology, in which indigenous people participate not just as research subjects but as collaborative partners in advancing scientific knowledge. The trans-disciplinary approach develops new conceptual, theoretical, and methodological innovations that transcend discipline-specific boundaries. Such innovations facilitate engagement between indigenous and non-indigenous stakeholders in addressing real-world challenges. This paper documents several Siberian ethnography exhibitions organized by the authors and evaluates their anthropological and social significance. Historically, anthropological discourse has championed using visual materials as tools for cultural interventions aimed at societal transformation. Building upon this foundation, this study explores the challenges of both the Russian Arctic and Asian contexts. The article guides the readers to reconsider conventional anthropological perspectives and methods of collaborating both with the indigenous and non-indigenous partners. By outlining the authors experiences in involving local stakeholders across different countries in these exhibitions, they illuminate the impact of the exhibitions on diverse cultural contexts. As cross-cultural visual anthropology endeavors, the exhibits redefine the meaning of ethnographical snapshots as scientific knowledge and go beyond repatriating indigenous cultures or sharing research outcomes with the broader society. The cross-cultural exhibition is becoming a novel research modality and a tool for fostering social interactions.journal articl
