Bridging the 39Ar–14C Groundwater Dating Gap: A Dual‐Permeability Transport Perspective Based on Numerical Modeling and Field Data

open access: yesWater Resources Research, Volume 61, Issue 12, December 2025.
Abstract Groundwater dating studies rely on environmental tracers to estimate residence times, but most available reliable tracers cover either short (days to decades; e.g., 222Rn, 3H/3He, 85Kr) or extended timescales (millennia to millions of years; e.g., 4He, 36Cl, 81Kr). This leaves a critical gap in age information for intermediate residence times (

Dendroclimatic Investigations of Pinus Sylvestris L. on Keretsky Archipelago Islands, the White Sea [PDF]

open access: yesЖурнал Сибирского федерального университета: Серия Биология, 2011
The radial growth dynamics of Pinus sylvestris from different habitats of Keretsky archipelago, the White Sea, was analyzed. Two tree-ring chronologies for dry pine forest and the third one for swamp habitat were built.

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 ...

Biomass production of tropical trees across space and time: The shifting roles of diameter growth and wood density

open access: yesJournal of Ecology, Volume 113, Issue 11, Page 3141-3158, November 2025.
Diameter growth is an important and good indicator of forest carbon production. However, size‐related changes in wood density, which are usually neglected, are critical for accurate short‐ and long‐term carbon assessments, especially in tropical humid sites.

Tree-Ring Chronology of Pedunculate Oak (Quercus robur) and its Potential for Development of Dendrochronological Research in Croatia

open access: yesDrvna Industrija, 2014
We present the local tree-ring chronology of pedunculate oak (Qercus robur) from Kobiljak near Zagreb, Croatia (16º09’ E, 45º49’ N, 140 m a.s.l.). The chronology is based on 17 trees and is 127 years long and covers the period of 1883-2009.

Streamflow Reconstructions Using Tree-Ring-Based Paleo Proxies for the Sava River Basin (Slovenia)

open access: yesHydrology, 2023
The Sava River Basin (SRB) extends across six countries (Slovenia, Croatia, Bosnia and Herzegovina, Serbia, Albania, and Montenegro) and is a major tributary of the Danube River (DR).

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.

Three centuries of Myanmar monsoon climate variability inferred from teak tree rings [PDF]

open access: yes, 2011
Asian monsoon extremes critically impact much of the globe's population. Key gaps in our understanding of monsoon climate remain due to sparse coverage of paleoclimatic information, despite intensified recent efforts.
