A 422-Year Reconstruction of the Kaiken River Streamflow, Xinjiang, Northwest China

Atmosphere, 2020
Our understanding of Central Asian historical streamflow variability is still limited because of short instrumental hydrologcial records. Based on tree-ring cores collected from three sampling sites in Kaiken River basin near Tien Shan, a regional tree ...

Approaching a thermal tipping point in the Eurasian boreal forest at its southern margin

Communications Earth & Environment, 2023
Climate change is increasing the intensity and frequency of extreme heat events. Ecological responses to extreme heat will depend on vegetation physiology and thermal tolerance.

Critical temperatures controlling the phenology and radial growth of Pinus sylvestris var. Mongolica on the southern margin of a cold temperate coniferous forest

Ecological Indicators, 2021
Temperature plays a key role in phenology and growth of dominant tree species and hence in the structure and function of coniferous forests in cold temperate zones.

The annual rhythmic differentiation of Populus davidiana growth–climate response under a warming climate in The Greater Hinggan Mountains

Global Ecology and Conservation, 2021
The stability and balance of forest ecosystems have been seriously affected by climate change. Herein, we use dendrochronological methods to investigate the radial growth and climate response of pioneer tree species in the southern margin of cold ...

Seven centuries of reconstructed Brahmaputra River discharge demonstrate underestimated high discharge and flood hazard frequency

Nature Communications, 2020
This study investigates flood hazards of the Brahmaputra River, Bangladesh. Based on a tree ring reconstruction of seasonal river discharge, climate modelling, and historic documentation of flood events, the authors suggest flood hazard risk is ...

Reconstructed summertime (June–July) streamflow dating back to 1788 CE in the Kazakh Uplands as inferred from tree rings

Journal of Hydrology: Regional Studies, 2022
Study region: Ishim-Tobol River Basin, Northern Kazakhstan Study focus: In this study, an ensemble reconstruction of the June–July streamflow from the Ishim-Tobor River was carried out using random forest (RF), K-nearest neighbor (KNN) and multiple ...

Robust Tree-Ring Detection [PDF]

, 2007
The study of tree-rings is a common task in dendrology. Usually the rings deliver information about the age of the tree, historic climate conditions and forest densities. Many different techniques exist to perform the tree-ring detection, but they commonly are semi-automatic.

Sampling bias overestimates climate change impacts on forest growth in the southwestern United States

Nature Communications, 2018
Sampling strategies may bias tree-ring datasets to not accurately represent the regional response to climate change. Here, Klesse et al. use a new representative dataset to show that the International Tree-Ring Data Bank in the U.S.

Research Communication: An International Tree-Ring Isotope Data Bank—A Proposed Repository For Tree-Ring Isotopic Data

, 2009
The International Tree-Ring Data Bank (ITRDB) is an invaluable resource, providing access to a massive and growing cache of tree-ring data. Oxygen, carbon, nitrogen and hydrogen isotope treering studies, which have provided valuable climatic and ...

Annual streamflow of Jinghe River basin in northern slope of Tianshan Mountains recorded by tree-ring during 1615—2007

Shui kexue jinzhan, 2014
Tree-ring width from northern slopes of Tianshan Mountains is of great potential for hydroclimate reconstruction. Tree-ring width data of Picea schrenkiana from two sites which are located at Jinghe River basin were collected and developed into tree-ring
