“…In this case, micro-drilling or scratching of calcium carbonate developed above/beneath rock art can be dated, thus offering not a direct age for rock art manufacture (as in the case of radiocarbon dating) but a limit ante quem (speleothem covering rock art) or post quem (rock are above speleothem) for its production. Samples of speleothems with paint in between were taken from caves for uranium-series dating on rock art from Europe [131][132][133] and Asia [111,134,135]. Carbonates are more stable than oxalates and Useries dating results are more reliable than other dating systems.…”

Rock art is a widespread cultural heritage, representing an immovable element of the material culture created on natural rocky supports. Paintings and petroglyphs can be found within caves and rock shelters or in open-air contexts and for that reason they are not isolated from the processes acting at the Earth surface. Consequently, rock art represents a sort of ecosystem because it is part of the complex and multidirectional interplay between the host rock, pigments, environmental parameters, and microbial communities. Such complexity results in several processes affecting rock art; some of them contribute to its destruction, others to its preservation. To understand the effects of such processes an interdisciplinary scientific approach is needed. In this contribution, we discuss the many processes acting at the rock interface—where rock art is present—and the multifaceted possibilities of scientific investigations—non-invasive or invasive—offered by the STEM disciplines. Finally, we suggest a sustainable approach to investigating rock art allowing to understand its production as well as its preservation and eventually suggest strategies to mitigate the risks threatening its stability.

“…230 Th/U dating work of five powdered subsamples for BJ7, weighing around 100 mg, were processed at the School of Geography, Nanjing Normal University. We used procedures for U/Th chemical separations and measurements as in [26]. Firstly, calcite powders were weighed and dissolved in 7N HNO 3 , mixed with a known quantity of in-home spike.…”

“…The data of uranium isotopes (including 233 U, 234 U, 235 U, 236 U and 238 U) were obtained on Faraday cups and thorium isotopes were measured on Faraday cups ( 232 Th) and secondary electron multiplier (including 229 Th and 230 Th). All the acquired data were processed using MATLAB software (version R2019b) as described in [26]. All the speleothem ages are in stratigraphic order with 2σ analytical errors (Table S1).…”

Multidecadal Monsoon Variations during the Early Last Deglaciation Revealed by Speleothem Record from Southwestern China

The Asian monsoon (AM) has direct and profound effects on the livelihoods of residents in South Asia and East Asia. Modern observations have shown multi-decadal alternations of flood and drought periods in these regions, likely influenced by climatic processes such as the Atlantic Multidecadal Oscillation and the Pacific Decadal Oscillation. However, our understanding of the multi-decadal variability of the AM under different climatic conditions remains uncertain. In this study, we collected an annually laminated and 780-mm stalagmite (sample number: BJ7) from Binjia (BJ) Cave in southwestern China, which is deeply influenced by the Asian monsoon system. Based on this sample, we established 6-year resolution and multi-proxy records for the Asian summer monsoon (ASM) variabilities during the early last termination, spanning from 18.2 to 16.1 ka BP. Measurements of five pairs of uranium and thorium solutions for 230Th dating were conducted using a multi-collector inductively coupled plasma mass spectrometer (MC-ICP- MS), and 374 pairs of stable isotope (δ18O and δ13C) analyses were run on a Kiel Carbonate Device connected with Finnigan MAT-253 at Nanjing Normal University. The chronology for this sample was established by annual layer counting anchored with 230Th dating results. Our BJ7 δ18O record replicates well with other Chinese δ18O records on the general trend, all of which are superimposed by frequent multidecadal-scale fluctuations at approximately 60 years periodicity. Inspection of the 60-year band in BJ7 δ18O and δ13C records and results of the cross-wavelet analysis indicate coherent changes in the ASM and biomass production/karst processes during most of the studied period. In addition, the 60-year band of BJ7 and NGRIP δ18O records are consistent, implying the impacts of the high-latitude North Atlantic or Atlantic Multidecadal Oscillation on the ASM. Our study suggests that the 60-year variability should be an intrinsic feature of the climate system regardless of glacial or interglacial backgrounds.

“…Consequently, many plants in these habitats have evolved physical or chemical defences, including thorns, tannins, polyphenols, alkaloids or cardenolides to deter herbivores (Charles‐Dominique et al ., 2016; Wigley et al ., 2019). Historical evidence, including early Holocene rock painting, suggests that the Jinsha River valley was once occupied by large herbivores such as deer, wild goats, bison, and wild cattle (Wu et al ., 2022). The presence of the open canopy and herbaceous layers allowed the survival of these large herbivores, and the area is currently used for grazing domestic livestock (Wang & Wang, 2003).…”

Aristolochia mimics stink bugs to repel vertebrate herbivores via TRPA1 activation

Summary Mimicry is the phenomenon in which one species (the mimic) closely resembles another (the model), enhancing its own fitness by deceiving a third party into interacting with it as if it were the model. In plants, mimicry is used primarily to gain fitness by withholding rewards from mutualists or deterring herbivores cost‐effectively. While extensive work has been documented on putative defence mimicry, limited investigation has been conducted in the field of chemical mimicry. In this study, we used field experiments, chemical analyses, behavioural assays, and electrophysiology, to test the hypothesis that the birthwort Aristolochia delavayi employs chemical mimicry by releasing leaf scent that closely resembles stink bug defensive compounds and repels vertebrate herbivores. We show that A. delavayi leaf scent is chemically and functionally similar to the generalized defensive volatiles of stink bugs and that the scent effectively deters vertebrate herbivores, likely through the activation of TRPA1 channels via (E)‐2‐alkenal compounds. This study provides an unequivocal example of chemical mimicry in plants, revealing intricate dynamics between plants and vertebrate herbivores. Our study underscores the potency of chemical volatiles in countering vertebrate herbivory, urging further research to uncover their potentially underestimated importance.
