“…The study area is in a first-cut native forest in the municipality of Óbidos, state of Pará, Amazon Biome in Brazil. In light of the different rainfall regimes in the Amazon Basin between the tributaries of the left and right banks due to the influence of the displacements of the Intertropical Convergence Zone (ITCZ) and the South Atlantic Convergence Zone (SACZ), respectively [19].…”

“…Santos et al (2020) created a chronology of the tree ring width of C. odorata in the eastern Amazon Basin, covering the years from 1786 to 2016, using dendrochronological techniques [18]. Based on the analysis of the growth rings and the use of oxygen isotopes, Pagotto et al (2021) suggested that this species can serve as an indicator of hydroclimatic variations [19]. Menezes et al (2022) studied the growth rings of C. odorata in a seasonally dry tropical forest in Brazil and identified a positive correlation with precipitation and a negative correlation with mean air temperature [20].…”

Half of the Amazon Forest, which has a marked seasonality in rainfall, is susceptible to intense droughts caused by positive phases of the El Niño-Southern Oscillation (ENSO). Cedrela odorata L., sensitive to climate variations, emerges as a promising candidate for studies on how trees respond to climate change. Given the demand for its wood and the imperative for its protection in the Amazon Biome, applying the principles of environmental sustainability becomes crucial. This study characterizes local climatic variables near the Amazon River and assesses their impact, as well as the effect of ENSO, on the radial growth of Cedrela odorata using Pearson correlation analyses. Ring synchronization followed the standard methodology in dendrochronology, confirming common growth patterns and the formation of growth rings in C. odorata. Significant correlations with growth were noted concerning local climate, with negative associations for maximum and average temperatures and evapotranspiration, and a positive correlation with relative air humidity. ENSO exhibited a significant negative correlation with growth rings, indicating reduced growth during El Niño events. The species is notably sensitive to water availability, particularly at the onset of the growth period. The study concludes that the growth of C. odorata in the Óbidos-PA microregion responds to climate change.

“…For example, wood density was measured by the method of X-ray densitometry (de Souza et al 2021). Mass spectrometry of δ 13 C and δ 18 O stable isotopes enabled extrapolation of stomatal conductance and transpiration when studying past event records in trees in the context of constantly changing climate (Mölder et al 2011; Pagotto et al 2021). Applying the method of thermogravimetry allowed us to establish that the in uence of the growing season climate conditions on the proportions of the main polymeric components of early and latewood tracheid walls differs between B. tortuosa and Larix sibirica (Siberian larch) (Tyutkova et al 2021).…”

Woody vegetation growth conditions have marked effects on hemicellulose, cellulose and lignin formation. In this study, we analyzed the climatic responses of these major cell wall polymers in Betula tortuosa. We studied 35 annual rings of B. tortuosa trees growing in the alpine forest-tundra of Kuznetsk Ala Tau using Fourier-transform infrared (FTIR) spectroscopy and pyrolysis gas chromatography mass spectrometry (Py-GC/MS). Our analysis of the correlation of the resulting spectra and Py-GC/MS values with mean air temperature and precipitation showed that the polymeric composition of B. tortuosa was mainly determined by June-August climate. The major factor limiting the development of the "unique" cell wall polymer composition of B. tortuosa found in alpine forest-tundra of Kuznetsk Ala Tau was a de cit of heat. At the end of the growing season, precipitation had largely a negative impact on polymer formation in B. tortuosa cell walls. We believe that combining FTIR spectroscopy and Py-GC/MS is an effective approach to quantifying the consequences of current climate trends for Siberian forest ecosystems.

“…Ice core, speleothem, and lake sediment δ 18 O records in the tropical Andes have been successfully utilised to report past hydroclimate variability at centennial to multi-millennial time scales [16][17][18] . Tree-ring δ 18 O records have demonstrated potential to assess annual-resolution hydroclimate changes for the last 40-200 years in tropical South America [19][20][21][22][23][24][25][26] . However, multi-century climate reconstructions based on tree-ring δ 18 O chronologies have not yet been developed for the Altiplano, a high-elevation plateau located in the southern tropical Andes.…”

Tropical South American climate is influenced by the South American Summer Monsoon and the El Niño Southern Oscillation. However, assessing natural hydroclimate variability in the region is hindered by the scarcity of long-term instrumental records. Here we present a tree-ring δ18O-based precipitation reconstruction for the South American Altiplano for 1700–2013 C.E., derived from Polylepis tarapacana tree rings. This record explains 56% of December–March instrumental precipitation variability in the Altiplano. The tree-ring δ18O chronology shows interannual (2–5 years) and decadal (~11 years) oscillations that are remarkably consistent with periodicities observed in Altiplano precipitation, central tropical Pacific sea surface temperatures, southern-tropical Andean ice core δ18O and tropical Pacific coral δ18O archives. These results demonstrate the value of annual-resolution tree-ring δ18O records to capture hydroclimate teleconnections and generate robust tropical climate reconstructions. This work contributes to a better understanding of global oxygen-isotope patterns, as well as atmospheric and oceanic processes across the tropics.
