Oxygen Isotopes as a Key Proxy of Equatorial Pacific SST Variability in a Multiparametric Tree‐Ring Approach in the Low‐Latitude Andes

open access: yesPaleoceanography and Paleoclimatology, Volume 40, Issue 9, September 2025.
Abstract Sea surface temperature (SST) variability in the equatorial Pacific plays a crucial role in shaping global climate patterns. As El Niño–Southern Oscillation (ENSO)‐related extremes intensify, understanding SST fluctuations and their connection to ENSO becomes increasingly important.

Provenance Variation in Functional Traits of European Forest Trees: Meta‐Analysis Reveals Effects of Taxa and Age Despite Critical Research Gaps

open access: yesEcology and Evolution, Volume 15, Issue 8, August 2025.
This meta‐analysis on intraspecific variation in European trees studied the frequency of provenance variation, provenance–environment interaction, clinal variation along the climate of origin or transfer distance. While identifying trait group specific patterns of variation, research gaps have been identified in terms of age and geographical ...

Sub‐Seasonal Tree‐Ring Reconstructions for More Comprehensive Climate Records in U.S. West Coast Watersheds

open access: yesGeophysical Research Letters, 2021
Tree‐ring records of preinstrumental hydroclimate, which contribute needed context for understanding recent drought and flood events, typically provide one value per year that represents the entire year or one particular season.

Reduced Temperature Sensitivity of Maximum Latewood Density Formation in High-Elevation Corsican Pines under Recent Warming

open access: yesAtmosphere, 2021
Maximum latewood density (MXD) measurements from long-lived Black pines (Pinus nigra spp. laricio) growing at the upper treeline in Corsica are one of the few archives to reconstruct southern European summer temperatures at annual resolution back into ...

Dendrochronology of sessile oak (Quercus petraea) on the transition between the sub-Mediterranean and temperate Continental climatic zones in Slovenia

open access: yesLes, 2018
A local tree-ring chronology of sessile oak (Qercus petraea) was constructed for the site Klanec pri Kozini (KLA), Slovenia (45.59° N, 13.92° E, 450 m a.s.l.) located on the Karst edge on the transition from the sub-Mediterranean climatic to temperate ...

June–July Temperature Reconstruction of Kashmir Valley from Tree Rings of Himalayan Pindrow Fir

open access: yesAtmosphere, 2021
The Himalaya is one of the major mountain ecosystems that is most likely to be impacted by climate change. The main drawback in understanding climate change in the remote Himalayan ecosystems is the lack of long-term instrumental climate records ...

Spring-Summer Temperatures Since AD 1780 Reconstructed from Stable Oxygen Isotope Ratios in White Spruce Tree-Rings from the Mackenzie Delta, Northwestern Canada [PDF]

open access: yes, 2013
High-latitude delta(exp 18)O archives deriving from meteoric water (e.g., tree-rings and ice-cores) can provide valuable information on past temperature variability, but stationarity of temperature signals in these archives depends on the stability of ...

A Proxy System Modeling Approach to Combining Tree‐Ring and Sediment‐Based Paleotempestological Records

open access: yesPaleoceanography and Paleoclimatology, Volume 39, Issue 9, September 2024.
Abstract The short and biased observational record of tropical cyclones (TCs) limits scientific understanding of how these destructive storms respond to climate forcing. Paleohurricane records use natural archives (tree rings, coarse‐grained sediment) to reconstruct TC properties (frequency and intensity of rainfall, wind) over the past few hundreds to

Influence of climatic conditions on growth rings of Salix uva-ursi Pursh from the southeastern shore of Hudson Bay, Subarctic Canada

open access: yesArctic, Antarctic, and Alpine Research, 2020
Over the past decades, warmer air temperature and spatiotemporal changes in the amount and patterns of precipitation have been observed at high latitudes.
