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

Paleoceanography 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.

Changing climate response in near-treeline bristlecone pine with elevation and aspect

Environmental Research Letters, 2014
In the White Mountains of California, eight bristlecone pine ( Pinus longaeva ) tree-ring width chronologies were developed from trees at upper treeline and just below upper treeline along North- and South-facing elevational transects from treeline to ...

Changes in climate-growth relationships and IADF formation over time of pine species (Pinus halepensis, P. pinaster and P. sylvestris) in Mediterranean environments

Forest Systems, 2015
Background: The Mediterranean basin has experienced an increase in the mean annual temperature, a decrease in the mean annual precipitation, and an increase in the frequency of severe drought periods during the second half of the 20th century.

Quantifying uncertainty in isotope dendroclimatology

The Holocene, 2013
To maximise the potential of the tree-ring isotopic signal for palaeoclimate research it is essential to understand and characterise the natural variability between individual trees. This study explores the nature of inter-tree isotopic variability and evaluates the implications for developing robust palaeoclimate reconstructions. We confirm levels of

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

Ecology 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 ...

Fine-scale modeling of bristlecone pine treeline position in the Great Basin, USA

Environmental Research Letters, 2017
Great Basin bristlecone pine ( Pinus longaeva ) and foxtail pine ( Pinus balfouriana ) are valuable paleoclimate resources due to their longevity and climatic sensitivity of their annually-resolved rings.

Monthly High‐Resolution Historical Climate Data for North America Since 1901

International Journal of Climatology, Volume 45, Issue 3, 15 March 2025.
The maximal use of station records and raster‐level optimization ensure robust interpolated monthly climate anomalies since 1901. These anomalies are integrated into ClimateNA to generate scale‐free monthly climate variables for any specific location in North America.

Dendroclimatological reconstructions in South America: A review

Palaeogeography, Palaeoclimatology, Palaeoecology, 2009
Abstract Recent years have seen a consolidation and expansion of tree-ring sample collection across South America. Most collections are concentrated in the temperate forests along the eastern and western slopes of the Southern Andes (32°S to 55°S).

Spruce up your climate analysis: Dendroclimatology of Picea engelmannii and Picea pungens

Ecosphere, Volume 15, Issue 11, November 2024.
Abstract Warming and more variable climates threaten to upend historical tree ranges, climatic sensitivity, and vigor. In western North America, the species Picea engelmannii var. engelmannii Parry ex Engelmann (Engelmann spruce) and Picea pungens Engelmann (Colorado blue spruce) are widespread spruce that act as foundational species in their montane ...

Dendrochronological Potential of Drought-Sensitive Tree Stands in Armenia for the Hydroclimate Reconstruction of the Lesser Caucasus

Atmosphere, 2021
Existing high-resolution reconstructions of hydroclimate variability in the Caucasus are lacking tree-ring data from Armenian Plateau, the most continental part of the region.
