An absolutely dated mid-Holocene English yew chronology offers new opportunities for archaeological and palaeoenvironmental research
Research on Holocene climate variability and human history greatly benefits from annually resolved and absolutely dated tree-ring chronologies. The quality and quantity of such records, however, decline back in time, with little tree-ring evidence available for the Early and Middle Holocene. Here, we present a tree-ring width (TRW) chronology from 100 subfossil yews ( Taxus baccata L.) excavated from peat-rich soils in the Fenland region of easte…
Tree-ring stable isotopes in cellulose and lignin methoxy groups reveal different age-related behaviour
Tree-ring stable isotopes (TRSI) have the unique ability to capture inter-annual to multi-millennial climate trends and extremes if the appropriate data and methods are combined. However, there is still an ongoing debate about age-related biases in TRSI measurements that potentially affect the fidelity of their chronologies and subsequent climate reconstructions. Here, we investigate carbon and oxygen TRSI measurements in cellulose (δ13Ccell and …
Dissolved and gaseous nitrogen losses in forests controlled by soil nutrient stoichiometry
Global chronic nitrogen (N) deposition to forests can alleviate ecosystem N limitation, with potentially wide ranging consequences for biodiversity, carbon sequestration, soil and surface water quality, and greenhouse gas emissions. However, the ability to predict these consequences requires improved quantification of hard-to-measure N fluxes, particularly N gas loss and soil N retention. Here we combine a unique set of long-term catchment N budg…
A millennium-long ‘Blue Ring’ chronology from the Spanish Pyrenees reveals severe ephemeral summer cooling after volcanic eruptions
‘ Blue Rings’ (BRs) are distinct wood anatomical anomalies recently discovered in several tree species from different sites. While it is evident that they are associated with a cooling-induced lack of cell wall lignification, BRs have yet to be evaluated systematically in paleoclimate studies. Here, we present a continuous wood anatomical assessment of 31 living and relict pine samples from a high-elevation site in the central Spanish Pyrenees th…
