Vessel characterization and ring-width of a multipurpose agroforestry tree species (Garcinia kola.(Heckel)) and its relationship with climate in Nigeria
Radial growth and wood anatomical variables of G. kola have a direct relationship with climate. Rainforest regions are more suitable and could be recommended for stakeholders for conservation action plans.

Open AccessTree-ring-based seasonal temperature reconstructions and ecological implications of recent warming on oak forest health in the Zagros Mountains, Iran
Abrupt changes in temperature have especially strong impacts on fragile ecosystems located in semi-arid regions. In this study, we analyzed tree-ring widths (TRW) of Mediterranean cypress (Cupressus sempervirens ...

Tropical tree growth driven by dry-season climate variability
Interannual variability in the global land carbon sink is strongly related to variations in tropical temperature and rainfall. This association suggests an important role for moisture-driven fluctuations in tr...

Ethiopian Church Forests as Monitoring Towers in Reconstructing Climate Change and Its Impacts and to Make Evidence-Based Climate-Smart Restoration Efforts
Climate change has become one of the biggest threats to nature and society, due to extreme weather events including floods, droughts, and increased frequency and intensity of dry spells. This has been causing ...

Oxygen isotopes in tree rings of Cedrela odorata L. as an indicator of hydroclimate variations in a seasonally dry tropical forest in northeastern Brazil
We present the first δ18O chronology of a tropical dry forest tree species in Brazil. Our results showed a strong relationship of δ18O with inter-annual variation of moisture conditions during the growing season.

Unexpected climate variability inferred from a 380-year tree-ring earlywood oxygen isotope record in the Karakoram, Northern Pakistan
To provide a long-term context for understanding the “Karakoram Anomaly” in recent glacier studies, we originally aimed to develop an annually resolved multi-century winter–spring precipitation record using tr...

High aboveground carbon stock of African tropical montane forests
Tropical forests store 40–50 per cent of terrestrial vegetation carbon1. However, spatial variations in aboveground live tree biomass carbon (AGC) stocks remain poorly understood, in particular in tropical montan...

Monsoon precipitation variations in Myanmar since AD 1770: linkage to tropical ocean‐atmospheric circulations
To understand inter-annual to decadal summer monsoon precipitation variations in Myanmar, we developed new tree-ring chronologies of Tectona grandis (teak) from three sampling sites in north-central Myanmar where...

Trends in tree growth and intrinsic water-use efficiency in the tropics under elevated CO2 and climate change
Increasing water-use efficiency, due to rising atmospheric CO2, did not stimulate radial growth in tropical trees, probably because negative impacts of changing climate on tree growth have overridden the small po...
